Time

Did anyone can slove this ????? You are going to make an item that's about time. You are free to interpret the term of time as you please. Examples may be special moments, repetitions, everyday events, or major events. Think about what expression the item should have. You can use shapes, colors, moving parts, technologies, humor, and the like. You can use the materials and techniques you want.

Electr'Ocarina of Time

Hi there! Okay so here i am with this idea i've been tackle with for weeks. Hold tight it's a long presentation. Brief Basically, i would like to make en electronic version of the Ocarina of time from Zelda. I would like to keep it really simple at least for the first step. So it will look like a proper ocarina but instead of holes there will be 6 arcade buttons ( Red, Green and 4 yellow as a reminder of the N64 gamepad buttons). Each button is assigned a note wich will be played while blowing through a microphone. The sound will be a synthesized sinewave that would be played thanks to a speaker. Will be great also if the device could work on a USB chargeable battery. I Have been doing researches on how to make it for a while now, though could'nt find exactly what i was looking for and not sure how to fit different parts together to make a worrkable fork. So i believe i have two options. As you may guess i am fairly new to electronics, programming and electronic music (Lol i read that all the times). To be as clear as possible i am gonna put some schemes of how i picture myself the electronic but i really don't know how it's supposed to be managed, i mean i know there will be some resistors, capacitors or whatever between the "function blocks" i draw but i have absolutely no clue of what should actually really appear. Option 1 - Analog So i made this stylophone few months ago : https://www.instructables.com/id/A-Stylophone/ It is based on a 555 timer (i also saw some mini synths based on this component). It felt to me as a good starting point. Volume would be controlled through the mic instead of a pot and i would get rid of the pitch pot and all the unecessary notes. But i would like it to sound more fluty and so i found this tuto on how to make a sinewave but don't know how to use it in this project (or even if possible) : http://www.learningaboutelectronics.com/Articles/Sine-wave-generator-circuit-with-a-555-timer.php Regarding the microphone part I've also seen this insctrutable but the synth seemed to me way over what i planed to do in terms of sound synthesis ability : https://www.instructables.com/id/Arduino-Flute-Synth/ Option 2 - Digital So comes option 2 wich consist in using an arduino to synthesize the wave that would play if microphone is HIGH and if button 1 is High key 1 would be played etc. The scheme I provided seem definitely wrong to me but that's a first shot anyway. About sound synthesis with arduino i found this library i havent gone through the tutorial yet but it seem a little bit picky. http://sensorium.github.io/Mozzi/ So as you see i am kinda lost and a little clarification would be awesomely nice. I am actually working in a fablab and i would like to develop this project to be used as a workshop. Im pretty sure lots of old grown up kids would love to get a little ocarina. There are some other options i would like to implement (regarding what happend if you press several buttons or none) but well first things first. Hope you like the Idea, hope you can help. Love, Starsheeps and Electro-cupcakes! Adrien

Storage Space for Parts

I'm sure me and Skunkbait aren't the only ones who have kept car or motorcycle parts in odd places.I hear my dad kept a motocycle in his living room for years, because the place didn't have a secure garage. For a little while, if you wanted to sit while watching TV, you had to sit on the bike or the floor, because there was no other furniture. Plus, it's just priceless to be able to ride out your front door.I know some folks who keep spare electical bits like turn signals and partial wiring harnesses laying around the house. Hanging on doorknobs. Apparently, bachelors, those aren't just for hanging underwear anymore.There have been a few times that the chainsaw and lawnmower had to live in the house so a visiting motorcycle could live in our shed.Generally, whenever I get a new part or tool home, it has to spend some time just sitting around while I try to figure out what the best way is to use it. Or just figure out why it looked like a good idea to buy another timing light.I've been known to hang particularly sexy motorcycle parts on the wall. I spent a lot of time trying to get a 10-120 speedometer from a Volvo to work as a clock one time. That didn't work, but it did make a good paperweight.Where have you kept parts, and why?

Delay for a timed switch?

Hi, I wont explain my purposes(maybe in an instructible if i get a good answer) but I need a simple(as in, requiring very few parts) schematic for a 555 timer. I need a setup where i have a battery, connected to a switch(the kind that you push, and it closes the circuit, then you push again, and it opens the circuit. I forget what its called) that goes to a 555 set to delay for 10 seconds. After the 10 seconds is up, it allows the electricity to go through. Anyone understand? If needed, I can upload a pic of what I need.

My time as an AiR

When I got the invitation to be an Artist in Residence, my wife's first reaction was hilarity, since I have the drawing skills of an orangutan. Getting here, and being here, has been a really big deal.  This site has been a big part of my life for several years, and it has been a real pleasure to share space with some of the most intelligent and creative people I have ever encountered.  I have seen genuine art being created, and wonderfully subversive acts being committed. Being in such an environment was, in equal parts, intimidating and exhilarating.  Although I have a long list of projects to try, I was sometimes spoiled for choice because of the freedom to create as I pleased. Projects I have created in my time here have been; Duct tape boomerang Paper bag kite Coffee stapler Cardboard conch Sculpted head Small-scale wave power generator (mentioned in the newsletter - woot!) Laser-cut penny maze Rock, Paper, Scissors board game Robot face stencil This is a shorter list than I would have liked (boy, you should see the length of my "to do" list!), but the downside of being given the freedom to create is the lack of enforced deadlines.  That is a failing on my part, and not a failing of the AIR system. On the up side, I have been involved in a lot more of the running and planning of the site than I thought I would.  I have judged contests, taken part in planning meetings, got involved in longer-term projects on the site, and helped de-bug the new AiR process (bring your bank details!).  The phrase dates me, but I grok the site a lot more now.  I've also seen the planned projects of the next guy, and they are awesome! I also got the chance to run a site Challenge to launch the new Birding Channel.  This was, I've got to say, disappointing - given the amount of publicity I managed to get for the challenge amongst the birding community, I had hoped for a lot more entries.  I guess that there are not many folk who are both Maker and Birder? I also got the opportunity to help out in other folks' projects, and to learn new skills, both traditional and modern (laser cutters are awesome!), from folk like Noah, Matt, Kelsey, and got a far clearer image of how hard, and how fun, it is to keep this site running. San Francisco is a great, mad, weird city, and I love it, but the most surreal day was being the witness to the wedding of an ex-pupil, who came over to the US to get married and have the honeymoon all at once.  I first met this person when they were nine, and now they're married... (I feel old again). It's hard, in a piece like this, to avoid rambling, so I'll stop now, except for one final point: This past month genuinely ranks as one of my top Life Experiences.  That may sound like an exaggeration, but if you know me, you know how important this site has been to me over the years.  Eric, if I ever get the chance to do it again, I will have your arm off at the elbow! And, you know, I think the rest of my family will as well ...

Dragon Samurai chapter 2

Hi! I decided I would post every chapter I do instead of just the first so here's the second chapter! Enjoy! Chapter 2 The traveller After eating some delicious noodles we decided to go to my house. I expected my mother would shout at me because I hadn’t made my bed, but when I got home there was a very different response. My mother looked very frightened. Suddenly my father walked in. He too was a samurai. He was dressed in samurai’s armour and had a katana and a wakizashi (Samurai sword and dagger) which were placed in their sheaths. He only wore the armour in an emergency and in times of war and the expression on his face told me that there was bad news. “Pack your bags, Ryu,” he said. “It’s time for you to go to the dojo.” “What?” I asked in disbelief. “Go and pack your bags,” he repeated. “Hiroshi, you must also get ready. Go home to your father who is waiting for you.” “Yes, sir,” he replied. Hiroshi never questioned my father’s decisions. “Father?” I started. “Do not question me, Ryu. Now go and get ready.” Hiroshi ran out the door and I went to my room and opened my cupboard. Inside were all my kimonos and my bokken (wooden sword). I grabbed my favourite ones and came back to where my father was waiting. I didn’t have time to say goodbye to any of my friends. We walked outside where my father’s horse stood ready. “Hello, Diamond,” I said. He whinnied when he saw me and put his head under my arms so that I could pat him. I scratched his ears while my father prepared the saddle. We named him Diamond because of the diamond shaped mark on his forehead. The white stallion was very rare and my father was lucky to have found him. I still remember the first time we met Diamond. My father and I were travelling on a large dirt road when it started to rain. The road quickly turned to mud so we took shelter under some trees. Hearing a sad whinny, I looked around and found a white stallion lying in the mud. I turned my father’s gaze to the horse and we walked over to it. It was only half awake and had a huge cut in its side. We brought it back to our stables and healed its wounds. It became fond of us so we decided to keep him. He was easily the fastest horse in the city. Back to the present, we set out on the road to the dojo. As we left the city I could see almost everything from the palace down to the pier. The gardens at the top of the hill were full of flowers and shrubs. It was bordered on two sides by a thick hedge. The pagoda was in the middle for people to visit. I realized that I had never actually visited the garden. There were many things I hadn’t visited in the last fourteen years. I would miss the beach with its crystal clear waters and sandy shores. I’d miss the constant movement of the waves. I’d miss my mother and younger sister. I’d especially miss all the friends I had. Leaving Hiroshi would hurt dearly. As we travelled I helped Diamond’s tail to flick away the flies. Diamond galloped so swiftly that it was comfortable riding him. The white stallion sped past villages and mountains until we arrived at a forest. The entrance to the forest was shrouded in mist and there was complete silence. Entering cautiously we heard a weak yelp. My father stopped and stared in the direction of the sound. I dismounted and walked toward the faint voice. My father told me to take my bokken. He always thought that curiosity was a great teacher. I got closer and heard a twitch. Behind a small bush a girl was lying unconscious. She looked about my age- fourteen or fifteen, maybe? She had a deep cut in here wrist that seemed to be from sometime of weapon. She had a large bump on her head which must have left her unconscious. The thing that really surprised me was her hair. It was the colour of gold. I called my father over to see. He stared at the girl and then picked her up. “The healers from the dojo will be able to heal her wounds,” he said. “Put her on your lap and make sure she does not fall of the horse.” I laid her on the horse and put my bokken between me and the saddle holding the girl in place. We continued our journey through the woods without another word. Halfway through the forest the girl started to wake up. She had crystal blue eyes that stared straight at me. “Danger,” she said before drifting back into unconsciousness. I had a bad feeling about this.

It's fine until it says restart my computer, after it does it it boots up like the driver didn't do anything. I'm using a realtek driver, I've both tried installing it off of the cd that comes with my computer and downloading the driver straight off of their site. I NEED SOUND!!!!

masynmachien's time as an AIR

I had the honour and pleasure of spending the month of July 2013 as an Artist in Residence at Instructables HQ. An unforgettable experience! I feel like I cannot even begin to describe it, so forgive me for keeping it simple. The most tangible amazing thing is the unbelievable workshop, a true makers heaven! I mainly worked on the laser cutters and the 3D printers myself, but these are just a part of the new workshop set up at Pier 9. There’s also the experimental kitchen, the sowing corner, the electronics lab, the high-end CNC machines, a complete wood shop and a full blown metal shop. More importantly however was working among the people behind Instructables. To experience up close how they work very hard to make Instructables not only the biggest and best Show-and-Tell buy also the best “maker medium” ever. Having just moved to the new facilities at Pier 9, there was a lot of extra work to get the workshop accessible and operational, but they moved mountains to get us Artists in Residence onto the machines and making things. Working alongside three other Artists in Residence was also unique chance. Usually, when I’m surrounded by makers, most of them aren’t older than 12. But even as each of us had his inner kid very much alive, having some serious making going on around you is very inspiring (as some of my Instructables will show). I also very much appreciate how my daughter Tika was warmly received when see joined me at Instructables HQ. One month was far too short to spend with the people at Instructables HQ.  I was constantly torn between on the one hand getting to know the people better and on the other hand leaving them continue there hard work and trying to make as much things as possible myself. And to make it even harder there were the lures of the magnificent city of San Francisco and of the Bay Area. My conclusion is clear: I want to come back! But then, being a month away from home is not easy either. Tika joined me during the second half of my stay, which was great, but I missed my wife and youngest daughter. Back home in Belgium I’m first taking some rest, spending time with family and friends, working on some due home improvements and preparing some kids workshops. Writing up the Instructables on the projects I did will take some time. They will be published over the coming months. After all, I have about 15 new projects to document. The thread through my AIR was a laser cut (advent) calendar. A series of toy/gift assembly kits designed to be laser cut out of one acrylic sheet and to be wrapped into a cardboard package opening separately on each kit. The only parts added to the laser cut parts are some elastic bands, screws and nuts. The idea is to have a calendar that is easily made in several copies, with designs accommodating for thickness variations in the acrylic sheet and a concept of cutting and wrapping it all with little handwork. I managed to design, cut and test 13 different toys/gifts. I consider it the first chapter of a full advent calendar. I will make an Instructable on each of the 13 and put them in a collection, together with an Instructable on the calendar concept. The eye catcher of my stay was an iPhone/iPad (or Android) controlled RC Blimp with video feedback. For this I used the plug-and-play Dension WIRC system. This system leading to rather heavy build (200g) comparted to my other blimp projects, I decided upon using a large spherical balloon. From this (and from watching Doctor Who) sprung the idea to make it into a large eye. I named it ‘In the blimp of an eye”. The project that was the most of a learning experience was designing and 3D printing nested dolls. Deviating from the classic Russian dolls, I learned how to design these in 123D Design, how to calculate sizes and experienced the possibilities and limitations of different 3D printing techniques. I hope you will enjoy reading the resulting Instructables, just as I enjoyed doing these projects at Instructables HQ. I want to thank once more the people at Instructables and Autodesk for this wonderful opportunity. Thank you, thank you, thank you! Yvon Masyn aka masynmachien

Where to find power knob for Lakewood model 101 box fan

Laser Driver with Limited Parts?

I have been working on a laser engraver for some time now, and have just recently gotten the laser parts.  I need to make a laser power supply, which I currently have a 5-volt fixed regulator which turns 15v 380ma into (obviously) 5v with roughly 400ma (value on label is not completely accurate).  I know that diodes will drop ~.6-volts, which I have a line of about 7 of them for testing, giving me 2-volts with the same current.  The problem I'm having is, I put proper resistors into the circuit to give 200ma to the diode, but every time I attach the laser to test the current it always reads 17ma on my volt meter.  Why is this?  How am I able to build a proper laser driver with limited parts (limited to a large supply of resistors and mixed caps, no adjustable regulator)?

"Oh, you must have too much time on your hands"

After showing off something that I've worked on or made there will be someone, usually anonymous on the internet, who will say, "This guy clearly has too much time on his hands."Yet these same people will gladly spend hours on blogs or on digg making comments. If there was ever a worthless way to throw away your voice online, commenting on digg is one of the best. Or maybe youtube. There's no point to that for anyone.For me it's a matter of priorities. I don't watch TV and only occasionally watch movies. I think that for many people it's possible to get free time. The hard part is deciding which way to use it. People are clearly willing to spend it on distractions. It was recently announced that the average WoW player spends 17 hours a week online. And according to the A.C. Nielsen Co. the average TV viewer watches 28 hours a week. That's a lot of building time.So when someone says that I have a lot of time on my hands I can just laugh and know that I'm putting my time where I want to. It helps that I don't have kids, I know, but there are many others in the same situation as myself who work hard on keeping up on their cultural knowledge and that's about it.Time to make something new.

Need Help Identifying Part

Guess what I acquired :) It sings and vacuums and is a robot :P Roomba! It's a first gen (I think), but it was cheaper than a new battery - and it came with a new (in box) battery :PThe problem came when I went to charge it. At first I thought it was fully charged - and the battery acted like it was (1 hour+ of runtime on carpet). But now, it won't charge.Skip ahead some time.I've narrowed it down to this component (see image). When I spray it with canned air liquid - the charger comes back to life. Not to mention, it looks scorched.I'm fairly certain it's a tantalum capacitor. Except, the PCB marks it as "F1" while other tantcaps are "C#" designated. Can anyone confirm/identify?Oh -- it's currently charging with the charge cct in the refrigerator. I'm using a Kill-o-watt to see if it overheats (current drops off) :P I'll be modifying the case with a cooling fan once I've replaced the component :)I've got to say though -- it's really fun to watch is honestly pretty effective and getting stuff out of our "clean" floor :P

I was looking at a camera slider and this motor for a time lapse slider: http://www.amazon.com/gp/product/B00436ULLA/ref=ox_sc_act_title_6?ie=UTF8&smid;=AUUK2J4ODEV5F I read somewhere online that someone used a rotisserie motor and hooked it up to a camera slider for a time lapse of about 40 minutes, but if I wanted to make the motor move even slower for a longer time lapse, can I hook up a potentiometer somewhere in the rotisserie motor? If so, what type of potentiometer should I get? Would this work: http://www.amazon.com/Parts-Express-10K-Ohm-Potentiometer/dp/B0002KRE20/ref=sr_1_1?s=industrial&ie;=UTF8&qid;=1355018144&sr;=1-1&keywords;=potentiometer

The worst time of my life

If three years ago somebody had told me that I would be at Maker Faire, using my cyborg arms, watching Arc Attack playing the “Doctor Who” theme, and meeting Adam Savage from “Mythbusters”, I would have said that person is crazy or is mocking me. But I was there. With Instructables. It was awesome when Adam Savage, in the middle of his conference, yelled to me “Hey man! Nice borg!!”. “OH MY GOD!” I thought, “ADAM SAVAGE FROM THE MYTHBUSTERS TOLD ME I MADE A NICE BORG!!” But, beyond Adam Savage, the giant robots, the fire and electricity shows, the beautiful steampunk women, the good energy, the delicious food and the pictures with Daleks; the most beautiful, shocking, awesome and magical moment of the Maker Faire 2013 was when I had just arrived at the Autodesk booth. I saw the giant map of DIYers from around the world, and I realized my picture and profile were representing Colombia and I was one of the three leading makers of South America. I was paralyzed remembering all this journey, from being a complete loser without a future to that point in time and space when I felt absolutely happy, calm, and at peace with myself. It was worth it to keep fighting, just for that sublime moment. I felt like a Rock Star. Not because I was, but because Instructables and Autodesk made me feel like one. ……………………………………… When people ask me “Why do you love Instructables?” my answers are always the same: because the site is awesome, has amazing projects and great contests with cool prizes; because Instructables is the only one who has supported my DIY activities, especially in my country (Colombia) where science and technology aren’t priorities, and so on. But I never gave the complete answer. And now, after these fantastic five months as Artist in Residence, I want to tell the truth: I love Instructables because they were with me in the worst time of my life. ……………………………………… In 2009, I lost my job as Security Analyst in an important Colombian company. I thought I could subsist thanks to my junk projects and creating my own business, but almost nobody was interested on buying recycled crafts (besides, I wasn’t as good then as I am today.) And the only interested people wanted my works for free. It was not enough for a living, so after a few months I started looking for a job. Due to its economic situation, Colombia has high rates of unemployment and it’s very hard to find a job, and there’s no government subsidy for unemployed workers (sorry Colombia! One day, I will talk about all your beautiful and fantastic things, because you have a lot. But not today). Besides, when you are a former military officer the only civilian jobs you can apply for are in security because nobody thinks you can be creative; and if you are, nobody takes you seriously. Every two weeks I had an interview. Every interview ended with just another “we will call you.” It’s time to confess something to the world: at the same time, I was diagnosed with mild Borderline Personality Disorder and depression. It’s not something that “SHAZAM! You are nuts!”. No. I knew from years ago there was something wrong about me, but just in that moment I found out what I have. Just in case you ask: no, this condition doesn’t make me a bad employee, and I’m very competent in my work. No, I’m not some kind of evil psycho. Just a little bit creepy sometimes, but I always try my best to be a good person. And no, I’m not trying to look like a “dark and bizarre, Tim Burton style” character just because I want to look interesting. It may work for an artist or a teenager, but not for somebody trying to get a job in the security business or a stable relationship. I didn’t have any health insurance; I didn’t have money for any treatment and, in case I could afford it, there is a social stigma about persons with some kind of mental disorder, and no company would be interested in hiring a security manager with that kind of problem. So, I had to keep it to myself. I didn’t even tell it to my family. And my girlfriend broke up with me. So, my life was “complete.” I was without a job, love and almost without my sanity. Almost all of my “friends” were gone. I was drowning in debts. I didn’t have money even for basic things. I had to return to my mother’s house. I lost every goal, every dream, and every hope. The situation was so desperate that I seriously thought about giving up. But only two things stopped me from doing that. One was Carolina, the only friend I had in that moment. The other thing was Instructables. ……………………………………… I found the site several months after because I was looking for simple robots ideas. Then, I saw Instructables has contests, and I entered my first project (the “SPD Exoskeleton”) for the 2009 Halloween Contest. A lot of people made awesome comments about my project, and I received my first prize: the “Photojojo!” book and a Robot T-Shirt. “What? I just post pictures of my project on an internet site and they give me free stuff? Interesting!” Then, I made another project, the “Valentine’s RoboGrinch”. I was a finalist in the 2010 Valentine’s Day Contest. People around the world commented about my ideas, and my projects started to become popular being featured in other sites and blogs around the planet. When I got the First Prize on the Dead Computer Contest, I gave to my mother the netbook I won. It was the only present I could afford to give her in a long time. In my darkest moments, when I thought about giving up, I remembered I had some project on Instructables I didn’t finish or publish, and then I keep fighting just one or two days more, because I didn’t want to leave it uncompleted. When I finished it, I endured one week more, just for knowing if it was successful in a contest. Sometimes I won. Sometimes I lost. When I could get some money, I used it for buying tools or materials for the projects, instead of food or paying debts. Because I started to think that every project, every idea I was making, every instructable I was writing, was my little legacy to humanity. Probably one day I will die, but at least in some part of the Internet, it would be a proof that I made something good, something that could be appreciated by anybody, and my life was not in vain. And I started to win more contests. It felt good, because I thought “I’m a loser, but this loser is kicking butts!” With so many fantastic authors, the competition got tougher, so I had to improve my skills (and my English. Instructables was the only opportunity I had to improve and practice this language.) I became very good at making stuff with plastic trash and limited resources! Besides, without knowing anything about me and my personal situation, even without being on the same country, the Instructables staff and community were (and are) very special and kind with me. They always made me feel respected and loved. Instructables was the only escape I had from my reality. This site has thousands of users and still they had the time to talk to me, to care for me, to make me feel like part of a bunch of friends! They were the only people that didn’t see me or treat me like a loser or somebody who needed to be pitied. They were the only ones that made me feel I wasn’t completely alone on this planet. All of this situation lasted one year and two months. Instructables kept me fighting almost all of that time. ……………………………………… Finally, in September of 2010, I got a job. It wasn’t the best (honestly, it was horrible!), but at least I was working. Four months later, I got a better job as security manager of a business center, enough to start paying debts. On October 2010, I went to the Colombian equivalent of Comic-Con, using the Cyborg suit I built for the Instructables’ Dead Computer Contest. Thanks to this, a beautiful woman found me out of the crowd, because she loves robots. She became my biggest fan and we shared a big love. I never thought I could find a love like that. She was the girlfriend I got thanks to Instructables! She was the inspiration of my “Cyborg Heart in a Can”. And I gave it to her. And then Instructables interviewed me as Featured Author. I would be the first Colombian to be a Featured Author! That was awesome! In total, I have won twelve Instructables contests and two challenges. Thanks to Instructables, people of all the world know about my cyborgs and my Roboplanters. (The funny thing is I’m still feeling like the black sheep of the family!) ……………………………………… It was 2012. After one and a half year of relationship, my girlfriend and I broke up, for good (our respective problems were stronger than our love.) Besides, I was stuck at work and I couldn’t study something art or robotics related because the restrictive schedule of my job. So, the depression was returning… I was lying on the couch watching “Doctor Who” when a phrase get stuck in my mind: “All of time and space. Everywhere and anywhere. Every star that ever was. Where do you want to start?” And then I realized that nothing was tying me to Colombia and I could apply to the Instructables Artist in Residence Program. I wanted to know, at least for a few months, how it was to be in the most awesome company in this world. So I quit my job, I sold most of my belongings, I packed my Dremel, my trench coat and my sonic screwdriver, I said goodbye to my family and I traveled to San Francisco on February 27th of 2013. I didn’t come for the “American Dream”. I came for the “Instructables Dream”! ……………………………………… What can I say? How can I describe the most fantastic experience of my life, using just a few words? How can I summarize five months of happiness, learnings, DIY and good energy, when every day was an amazing adventure? I felt, after 35 years of life, I finally arrived in the place I belong. I met the faces behind the site I love and admire. You know who they are (sorry for breaking the magic but, please! Update the Instructables Team page! A lot of awesome people are not there!) I’m trying to not mention specific persons, because I shared awesome experiences with each one of you. Every one of you taught me something, every one of you made me feel appreciated, every one of you does a fantastic job keeping this site working. And I want nobody feels excluded of this post (Sherry always fights for sending out prizes on time, silently. Why nobody says “Thanks Sherry?”) Because Instructables is more than servers and computers and projects and internet. Instructables is the people. From the beginning, Instructables and the Autodesk Consumer Group made me feel like one of the team, like part of something bigger than myself. The Pizza Thursdays, the Marvelous Mondays, the Build Days, the Design Nights, became magical events for me. But it wasn’t only Instructables and Autodesk. This beautiful city of San Francisco taught me real lessons about tolerance, respect and being yourself. It doesn’t matter if you are radically different to the other people. Just be a nice person, do your job and respect the others, and everyone will respect you. I had never touched a CAD software, because I didn’t see any possible use for it in my life. And I thought it was something so complicated that only engineers and designers could use that kind of program. But then I went from 0 to 123D Design! I learned the basics in just two days and I fell in love with this awesome program, and it’s free! (But, seriously guys, try to fix that problem with the crashes. Everyone in the lab knew that when I screamed, it was because the program had a crash and I hadn’t saved the progress). And later, I learned how to use a 3D printer, a machine beyond my wildest dreams! I remember the infinite sadness the first time I went to the amazing Pier 9 (new installations of Instructables and the Autodesk Consumer Group) and thought I could never try that fantastic technology; and the happiness when Noah told me I could stay two months more! You have all the best freaking hi-tech tools in this freaking world, and you don’t need to be a NASA scientist or a millionaire to use them! This place is waiting for people of all the world, to come with their ideas! (It doesn’t matter how crazy they are). 3D printers, laser cutters, a water jet, a bunch of expensive machines I still don’t know the names of, an awesome test kitchen, metal and wood shops, even a sewing area! And all available for the DIY community! But, more than being on Pier 9 because the fantastic machines, I loved to stay here because Instructables.  My life has good things and bad things, successes and failures. But being part of Instructables and sharing moments with all of you has been the most memorable experience of my whole existence! ……………………………………… I want to say something to my dear friends of Instructables and Autodesk: if one day, for some inexplicable reason, you feel like your work is meaningless, you don’t like it’s Monday or simply you forgot what this is all about, just remember something: you will never know exactly how many lives Instructables has touched: how many persons found their true calling thanks to the projects, and how many persons found a hobby that makes their life happier. How many couples fell in love thanks to the delicious recipes and romantic crafts, and how many parents shared precious moments with their sons building something. But now you will always know, at least, Instructables and Autodesk saved one life. My life! ……………………………………… I wish to finish my post with some “Doctor Who” quote. I love “Doctor Who”, because is all about being awesome and optimistic and keep smiling even in the worst situations or despite you are feeling absolutely sad and alone. And the series has a lot of badass and beautiful quotes! But now, when I have to start packing my bags, when I have to return to my hometown where I have to pretend I’m a “normal” person and try to get a “normal” job again, when I have to say goodbye to my coworkers (that are at the same time most of the only real friends I have had in my life), and to the greatest organization I have had the honor of being part (where for first time in life I felt truly appreciated, respected and loved, and happy because it was Monday and I could go to work in a company that is making of this world a better place); there’s one, and only one phrase that I got stuck on my head; the last words of David Tennant as the Tenth Doctor when, standing alone after saying goodbye to his loved ones (and to the most awesome time of his life), his final moment comes: “I don’t want to go.” Mario Caicedo Langer Former Artist in Residence.

Sunday mentoring session was the best time I've had in a LONG time.....

I had wanted to post this yesterday,  and I had it ALL written out but just before I wanted to hit enter, I had to back space to fix a misspelling and the whole browser backed up and wiped it ALL out. *sigh* Anyways, this past Sunday, after meeting, my wife and I were invited to stay and do some things with the children and the parents of that particular household. This is the family with the Asperger's child of 8 that built the Scorpion model/puzzle with me (see instructable for details on that build). I had sooo much planned, but we didn't get to half of it.  Which is ok, more to do another day.  I fixed her robot (last time the ground wire had broken off the motor, this time it was the red wire) by soldering the loose wire back on.  The battery compartment was broken too, so the one end of the "box" that joined the positive and negative terminals of the two batteries, was completely off. Thankfully, I had brought my hot glue gun. A more permanant fix would need to be done later if this didn't hold.  Anyway, I demonstrated the Magus effect to her, first showing her a ball rolling off a flat piece of cardboard, then asked her what she expected the paper tube to do when I rolled IT off the plane. She wasn't sure but after a bit of prodding she said it would act like the ball, only slower.  When she saw the tube roll of and reverse direction she had to see it again (to make sure I hadn't done something TO the tube :-)   THEN she just HAD to show the rest of the family   :-) The hardest part was explaing the effect to an 8 year old.  She is smart, but not very advanced language-wise. So I had to keep it fairly simple. STILL the experience was great. When I made a "voice box" out of a drinking straw and a balloon, though, she was tickled pink. She just HAD to have one, despite the great difficulty in operating it. I promised to think more on how to make it easier to use by the next session.  All in all, my head was spinning, and I was giddy all the way through Monday from the encounter.  I do think I missed my calling in life....

Leaving China and Taking a Part With Me.

My time was short, it seems my time is always short. Groggily I was pulled from bed the day after the Maker Faire. Spending the night at Eric's place was so wonderful, it was my first nights sleep since leaving America a few days earlier. We loaded Eric Pans car with gear and headed out to pick up a 3D printer. 3D printing technology is booming in the states, nearly every hackerspace in America has a Makerbot and design firms have Shapeways to turn to to get their rapid prototyping. But elsewhere in the world these things are still fresh! Sharing tools is something I love to do because you never know where people's creativity will take them. You never can know all the problems in the world, but all the people know all their problems! One of my missions then is to share low cost and open technologies to people I think can make awesome use of them! The night before after the Shenzhen Maker Faire all the Makers were invited to a gathering. Beer, frogs on skewers and peanuts were all provided free of charge. We ate, drank, wheeled and dealed. Wiess Tech is a filament company in Shenzhen and they have started noticing that more and more of their customers were 3D printers. Especially DIY 3D printers. So they've begun to make Makerbot replicas with some modifications. And there I was - I wanted a 3D printer to bring with me to Beirut and they wanted… Well, I wasn't sure. The language barrier between us was strong. Somehow Eric and I convinced them that it would be a good idea to give me a machine, and perhaps I'd pay them back when I got to the states. At this point I was at $244 dollars and dropping and I couldn't even afford the incredible hackerspace price the company was offering of $500 dollars! They agreed, and that's how I found myself rushing off to their head quarters the next morning before catching my ship. But first. We must go to Seeed Studio to buy a cup of coffee from the robotic tweeting (QQ) coffee machine in their break room. Hahaha! We headed out to Wiess Tech and on the way there we drive by construction zone after construction zone. Aparently Shenzhen didn't exist 30 years ago, and now you can still see the signs of a rapid expansion. Everything here is growing at an incredible pace, and apparently even maker culture. We arrive at Wiess HQ, which is housed in a 30 story complex decked out with multiple confusing entrances, cafeterias and dual elevators for the odd and even numbered floors. After spending a bit of time wondering how to get to floor 22 and circling the building, we found ourselves face to face with a small crew of about 8people. A few people managing papers, a secretary, some of the marketing team, and one guy sitting at a table putting together Wiess Tech versions of the thingimatic. After speaking with them we find that they also sell a machines based around the Reprap project, one of the earliest open 3D printing projects and have in the works a few models of their own designs. I'm excited to see how Weiss Tech bootstraps itself off of open sourced designs and starts producing their own versions! I hope to see a whole new generation of better, faster and cheaper machines that stay open! Go Weiss Tech! Heading out to take a 3D panorama from their deck Eric rushes and tells me that my ship leaves in 20 mins and that the time is now. After an awkward moment or two talking about paypal and me giving them advice on staying open we undo all their packing (too bulky) throw the machine into my luggage and run. In the car Eric and I discuss the future of Chinese makers. It really seems this is just the start of something much larger. It's an exciting time, his company is building great products, more Chinese companies are looking at open source technologies and more people are calling themselves makers. Perhaps it's through Maker culture China will be able to become more than the King of manufacturing, but also participate in producing quality designs and solving serious problems. Leaving China, the baggage handlers on the ferry were rough handling Adriana, my 3D printer, and it really cut deep. But as I watched Shenzhen bay slowly recede, I knew the next time i came back, again, everything would again be different. This is the pace of China and yet it seems softened by the fog falling over the rolling green hills. +Bilal Ghalib

The Ice King's Crown

It's my take on the Ice King's crown. For the "gold" part, I first tried gluing plastic paint buckets together, but they were too thin. I ended up covering the outside of one bucket in Bondo and then cutting in the peaks with a jeweler's saw. For the jewels, I cut a positive mold for each one out of a scrap of cutting board, then pressed them into clay to make a negative mold. Then I mixed up some casting resin and red dye and cast the jewels. They were epoxied onto the crown before I locked them in with Bondo bezels. If I were to do it again, I would use a more acute conic shape and make the peaks taller. I might also use fiberglass-reinforced Bondo and try a different gold paint. If I'm real adventurous I'll cast the thing out of scrap aluminum.

Timed control board for a reversible motor

Hello, In need to connect a control board to a reversible motor so that the motor would rotate in one direction for "x" seconds and then automatically switch and rotate for "y" seconds in a reverse direction. I got the following parts in hand: - reversible motor - https://www.amazon.com/gp/product/B01N687NGU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc;=1 - control board - https://www.amazon.com/gp/product/B01HB1X75U/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc;=1 - DC adapter - https://www.amazon.com/gp/product/B00S1GRFYY/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc;=1 Control board works and is going through the proper cycle as indicated in description however the motor only rotates in one direction and never switches. Realizing this this something that I am doing wrong with wiring, so hoping for an advice from someone who knows better in terms of how to set it up correctly and which jumpers or anything need to present so that it works and where things should be wired into. I am also attaching an image with descriptions for connectors that I received from the company. Thank you in advance for your advice.

I use TigerDirect for computer parts

. I've had good luck ordering computer parts from TigerDirect.com. Wide selection and reasonable prices. I've been using them for 5-6 years now.. Sales support can be spotty; sometimes you get a salesperson that will lean over backwards to make sure you get what you need and other times they seem to be apathetic. Luckily, the former prevails.. I've only had to make one return and it went without a hitch.. The web site has an excellent search. When you search for, say, "monitor" the results page will have links to different size ranges and price ranges, allowing one to easily drill down to the right product.. . Disclaimer: My only connection to TigerDirect is as a satisfied customer.

Time-Lapse shows the beauty of the galaxy we live in.

I recently purchased a Canon EOS DSLR.This video made it painfully obvious what I need to be doing with it!This gorgeous video is a compilation of shots taken with a Canon EOS-5D every 20 seconds over about nine hours at a star party in Fort Davis, Texas. It's a humbling sight.The Canon was equipped with a fisheye lens (an EF 15mm f/2.8 lens) and powered with an external battery to capture all that goodness. The more interesting part is the replacement anti-alias filter the photographer, William Castleman, used: The Canon's stock AA filter blocks out certain red wavelengths to achieve a "more desirable" skin tone, but if it's replaced with a filter that lets those wavelengths in, you've got yourself a camera capable of shooting a galaxy, as seen here, even if we can't see it with the naked eye.Its also great to know about the filter, I am off to google more into that now!Check it out on VimeoVia Gizmodo

Octopart - search engine for electronic parts

Two weeks ago I met with Andres and Sam of Octopart. Andres had literally dropped out of graduate school the day before to join Sam full-time building their search engine for electronic parts. You enter the part number, or simply its title or use, and Octopart returns the best matched specific components, their prices and availability from several suppliers, and links to the relevant catalog pages. I wish this had existed back in 1998. At the time, I was in charge of building the power controller for a web-controlled, wireless robot with a live video feed as part of the ultimate class in MIT's undergraduate mechanical engineering program, 2.009 Product Design. What is now a relatively easy task, was really kicking my butt then. After two painstakingly hand-built MOSFET H-bridges driven by charge pumps had exploded in my face, I was at my wits ends. I knew there had to be a better solution, but could not find it anywhere. At one stage, I even sat down with the Digikey catalog, and started reading through all of the components in the sections I thought might have something relevant. Pop "h-bridge" into Octopart and the fourth result is my favorite chip (and what eventually saved my skin in 2.009), the LMD18200. Hey look, the cheapest price with the highest availability is at Digikey, I think I'll get it there...Octopart is pretty cool as is, and I'm sure there will soon be lots more distributors. What's even more exciting, in my opinion, is the concept of Octopart searching through a webpage, determining what specific parts are mentioned, and generating a personalized shopping cart with the cheapest and most readily available parts. When we spoke, Andres and Sam said it might be a few months until they were ready to release at all - it would seem quiting grad school has been good to Octopart, so I'm sure cool new additions are right around the corner.

My apologies all.....

 Hey, just wanted to apologize for my not being around much of late.   My Mom has had to have 2 glaucoma and and 2 cataract surgeries and all the prep and followup appointments etc.  all have taken a bit of a toll on me, and definitely on my free time. I WILL be getting back to the forums as soon as things are more "level" and less hectic....meanwhile, I have a few ideas for some projects if I can get some hardware cheap at a few garage sales before the season closes.  I am still gathering a few parts for my "vintage" radio projects I have planned for later too.

Suggestions for another part of the heliostat is needed!

Https://www.instructables.com/id/HELIOSTAT/First of all thank you especially forgesmith for your help. Now is the time for the replacement for the rubber bands (to split the distance) in the plan. Any ideas? My twin spools that retract like a tape measure can work. Also 2 "geared" wires with a gearwheel in the middle would work. The centre of the reflector be joined to a piece that passes through the gearwheel.(I will draw it later!) Anyways, hope to get some answers. Thank you BrianThe part of the question below has been answered!Basically i have to attach the reflector so that it can swivel round the mounting.The way old farm tractor 3 point linkages worked on the back would be perfect. The side arms have a little ball in them and you put a shaft on the attached plough or whatever through a hole in the ball and fasened it with a clip. Imagine the reflector in place of the side arm and you have a perfect attachment BUT there is probably a modern urban alternative. Can you think of one?I am in no big rush myself because I have a big work project to complete but suggestions would be awesome for the near future.Thank you Brian White

1st time robot. Too ambitious?

Hello All, I have recently started an ambitious project. There will certainly be much learning along the way.  But it is too ambitious? The goal is to build a bot that can be controlled remotely, to aid in the detection, marking, and ultimate removal of unexploded ordinance in Cambodia (in this first application).  Though I have never built a robot of any type, I am quickly learning the basics, but would like ultimate beginner advice if anyone had any.  If anyone would like details on the project, PM me.  It's really a lot for a forum post... If there are any Veterans or military buffs out there, I could really use other first hand accounts of experiencing UEO. Through generous donation and aquisition, I have come cross an electric wheelchair, and many parts needed for a former "Battle-Bot".  Battle-bot turns peace-maker.  I love it!  The motors are Bosche, 24V and ~750watts.  Included were DC motor (high amp) speed controls, and 2x 12v 26A sealed lead-acid batteries.  Very very excited to really dig in.  I lack a quality track or model of a good track to use for traction, etc.  Anyone know of any good and sturdy RC tank tracks I could look at for design or actual construction? Though I began to construct my own track out of sheet metal and various materials available (it actually turned out kinda ok), I don't intend on reinventing the wheel, as it were.  3" took me almost 2 hours. Will also be incorporating a ~3'-4' rotating and articulating arm.  Trying to keep its weight to under ~30lbs.  The wheelchair frame is very strong and moddable, Ws thinking of using a lazy susan type bearing, but I'm not sure I could find one rated for that weight for an affordable price.  Any suggestions? Thanks for checking this out.  Again, if you want more details, I'm happy to share my plans.  Just PM me. This is being designed 100% open-source, and 100% documented with a video and written journal in order to be easily duplicated.   Constructive criticism is NOT personal criticism! Huck
