Hi there, I have an idea in mind but not the necessary skills. It would be nice if someone would be willing to help. my project requires a good knowledge of arduino and accelerometers. So if anyone is interested then pm me. I just need the schematic and the code. Please pm me so that we can negotiate. thanks.

I just got an ipod touch for christmas, and I'm going to be making an accessory for it that's like a laptop, and I'll call it an iTop or something like that. Anyways It's a tiny bit bigger than the ipod touch, the ipod touch will fold up and be the screen, here what the features of the bottom part will be (The ipod plugs in via the dock connector. High quality audio output Video output mini usb for easy syncing a speaker with an amp and a lion battery to power it a little lion charger a switch to wheather you want output audio or from the speaker I/O ports* *There will be a picmicro in it, and I'm going to make it so that if you output different frequencies (maybe some programmer could helpme) the pic will do different things. I posted on make a while ago how cool it would be to have an open source ipod, and this is the closest you can get. There might be anywhere from 4 to 20 I/O ports, and it'll be controlled by the ipod. Can any of you think of anything else to add before I buy stuff?

I just recently joined Instructables, and I'm looking for cheap (not necessarily simple) projects that involve mechanics or making anything out of easily found materials. Something like LostRite's hidden blade or this Mechanical Hand. I'm in high school and don't yet have a job, so many of the projects i find are out of my budget. Thanks for any of your suggestions!

A friend of mine is in the metals class at my school and he asked me for some ideas (since they can make whatever the want on this last project) on what his final project should be. He's thinking something like a trebuchet or something else that launches projectiles and causes pain (or just fun). It would be awesome if some of you had any ideas or instructables for his project. If you do, please tell me!

It sure would be nice to have a summary form for each project on the first page detailing the category, a description of the project, a difficulty level rating, estimated cost, estimated time, etc. There's tons of cool projects on here but if they're too difficult or too complicated I don't want to spend the time to discover that on my own. Would be nice to know right from the get go. Also, it would be useful for searching to find easier and/or less expensive projects if desired. Additionally, users who complete the project could also put feedback in some type of survey to capture costs, time spent, difficulty, etc. Doing this would add a great deal of consistency to the instructable projects and I think would add a lot of value to this site! Peace, ~Will

Whenever I have Microsoft Project open to read mpp document, it brings the whole system operation to a crawl. Forget about using a browser whenever that program is open; it slows everything down. Any suggestions as to what causes this?

Has anyone ever gotten outside funding for a project you were building? I have an idea for a device to make our local greenway trail safer but my investment in it would be at least a couple hundred dollars. I'm looking for ideas to gather outside funding for the project because it will benefit everyone who uses those trails. Because i am an individual and not an organization, my chances of getting grant money (even a mere $200) are slim.

What is one to do if they start a collaboration and someone else steals it out from under them and publishes it as their own Instructable? The Colaboration system is too flawed and I will never consider working on projects publicly again. They should be hidden from view of all but members of the collaboration itself. I had a project titled USB UPS and opened it for collaboration. A user (neelandan) saw it, copied the idea, threw together amateurish circuits and published the parts to it as his own. I had planned on publishing a very professional step-by-step for a usable project. Now the idea is moot since it's already been published.

Hi, I just want to inform you about a new project, which bring a tiny microcontroller board for your home automatication, to you. It is called "USBeDuino". What is USBeDuino? basically it is a microcontroller board with 3 shields, which, when combined make a very great platform for home automatication. Features: Processor: Attiny85 2 x 3A PWM Output sink channel 3 x Analog input channel 1 onboard poti 2 onboard Buttons Input Voltage 5-24V Small size The idea behind the board: Sometimes you need only projects with very less pins, such as light controlling or pump controll (in the garden). Then you dont want to use a full arduino, with a power or a relay shield... then you can use the USbeDuino! https://www.indiegogo.com/projects/usbeduino-project-all-or-nothing#home Please tell me, what do you think about this project? Does it have potential?

I notice that you are presenting more projects in French and Spanish. I think this is a very good objective. But, I am a uni-lingual person (English). I have tried to get Google to translate these projects, which can be a hassle, but all the images and their references are lost. Is there a simple way to get the PDF translated (or have access to an English version) I'm not suggesting that the original version be dropped, as translations can have errors! but can an English version be available or a procedure that I could do to get it translated with the image and graphic content intact?

Hi! Im gonna try out this project, Telescope , as I know nothing about optic or lens function maybe someone could just let me know if I should go for a Tele-Auto 6.3/400 mm or a Sigma 70-300 mm F4-5,6 DL Macro Super. I asked the creator but as time runs out for me I hope this gives a faster response =) Thanks

Does anyone have a Drawer Project? I have a space under the kitchen sink. The dimension is 15cm x 51cm x 52 cm. This space should be used for a dishwasher. I have seen some drawer projects using wood glue, but I would like to use screws instead of glue. This drawer will be used for cutlery, so it is good to have some divisions for fork, spoon, big knifes etc. As the whole kithcne furniture is white, the drawer shall be white for sure. I would like some tips such as track instalation, handle installation, bottom installation, finishing etc I intend to use my new Dremel to make it. Thank you!

I've seen many high altitude balloon projects and many rocketry projects on the web. These seem to be pretty established hobbies. The I got to wondering if anyone out there had ever heard of any amateur rockoon projects? If you haven't heard of a rockoon, it is a combination of the word "rocket" and "balloon". The concept is that a balloon is used to tow a rocket to a high altitude and then lauched. When I've searched around, most of the references I find are to the use of rockoons by Van Allen (of radiation belt fame)in the course of his research back in the 1950's. The only thing close to anything like an amateur attempt that I found on the web was by a group called JP Aerospace back in the 90's. I'm not necessarily contemplating any such project myself, I just find it a fascinating possiblity. And like the many amateur high altitude balloon lauches and high power rocketry, it is amazing what people put together. I wonder if it would be feasible for a high altitude balloon plus high powered model rocket to ever technically reach the internationally recognized altitude of ~100km considered "outer space". I know that both high altitude balloons and high powered rocketry have their own FAA (or equivalent agency) approval hoops to jump through. Perhaps they just wouldn't allow it, or it would be so much red tape that no one attempts it. Even a low altitude rockoon, of a small ~3ft diameter weather balloon towing a standard model rocket would be an interesting project, for the technical challenge of pulling it off successfully. Anyway, if anyone has ever heard of amateur rockoon attempts or your own musings on the topic, I'd be interested in hearing about it!

Well, I am bored, so I thought I would give an outline of my planned projects I have planned so far. They are in the order I plan upon doing them, and I am going to attempt to give a rough estimate of how long it will take me. First up there is a dragon. It leans towards the European side, if a little flatter than what is considered "normal". I have most of him complete, and he should be completed by next Monday. (He is completed and you can find him here I can't say anything about this project at the moment, as it is a gift for another instructables member. The project itself will take two or three weeks and be posted at the beginning of June. (This project is done, but can not be posted yet) Next I have a triforce from the Legend of Zelda franchise planned. It will be three dimensial, and I hope to make it able to stand up on its own. It will take a week, maybe two. (Completed and can be found here) Most likely to be the last project started in May, I want to make a jumping mouse from the movie Coraline. The key word there is want. I may not be able to follow through on it. It all depends if I can find a way to do all of the small pieces well, and if I can find a yarn color that I like. These are all projects that I want to do, but do not have a date or an order to do them in. The last project could be placed down here, but I know I will spend at least a day figuring out if I can do it or not at the end of May. Finishing up a simple, but tedious project I have started a good while ago. I may just take it with me when I go places and work it when I am going places. I don't know. It needs to get done though. The project, by the way, is crocheting with thread around a headphone cord. Very tedious. In case you missed it, I have a thing for dragons, and I also want an oriental dragon. So that will happen at some point. For yet another dragon, I have a little one that I cartoon sometimes that I would like to make a version of. I m not sure if I really want to make, but at the same time I do. I also want another hat. I have several hats already, but there is a really cute one I saw that I want to make. I want to make another pokemon. Maybe a Skrelp or a Dralage or perhaps a life size Joltik. One other note is, I am a student and final exams are approaching rapidly. It is entirely and likely possible that the projects will be delayed slightly due to extra study time. June Update: The next project is going to be a Skrelp from the Pokemon franchise. It has not been started but it is slotted to. I have recently purchased a jig, so I will be playing with it a lot. I may just be copying other's designs, but a few of my own my slip through as well. I have tentative plans to recreate Kyube from Madoka Magica. I have several papercraft projects spinning around in my head. Mostly drawing out templates to recreate some of my favorite characters. I am unsure if I will post them on instructables, as I am unsure as how I would manage it. If any one has any suggestions, I would love to here them. I have an instructable planned on how to do negative word art, and one working with zentangles as well. It will be a while before either happens, as I want more practice first.

I'm REALLY bored at work at the moment and need a personal project to distract me. The problem with past projects is I often run into problems or lose interest and they fall by the wayside. I was thinking that if the project was a collaboration I'd be more motivated and could call on people with better skills than me. Anyways I'll propose a few projects, and let me know if you are interested. Or if you've got an idea, post it up. I'd love to do something robotics related, but m programming skills aren't great. I can use "wrapper" environments, like Matlab and Arduino, but raw C++ isn't a strong point. I've got access to all the CAD stuff that would ever be needed, Pro/E, Solidworks, AutoCAD, ANSYS, Strand7. I've got some skills in and access to composite manufacturing, like carbon fibre and glass but no vacuum baggin facilities anymore. My first project idea is a bargraph type watch - kind of like the awesome binary watches here, but the time increments on a bargraph. I think only one bargraph to show the minutes would be necessary - you pretty much know the hour most of the time, and you could work it out using the minutes if it's around the hour. A ten segment display would give resolution of 6 minutes - good enough for most purposes. I could do the hardware layout and manufacturing for this project, but I don't think I could do the programming. how about a homemade SMS device? not the most practical when mobile phones are so small and cheap and would be WAY more fully featured, but I think it would be cool to have a homemade device that could at least send SMSs. Open source, single sided PCB, would be awesome. obviosuly as small as possible but maybe aim for something the size of a blackberry of treo? Not stylish maybe but maximum hacker cred thumb keyboard ---> microcontroller ---> cellular module&LCD GPS based car locator - I know this functionality exists in modern cars but certainly not my 1994 feroza - a box that sits in your car that SMSs you GPS coordinates if your car alarm is activated. I've been looking for this for ages in a commercial product but the prices are outrageous. Other more outlandish projects are a CNC machine and single sided, through-hole, no (or very little) programming MP3 player Any ideas?

Here is what I got going; I want to use a 9v battery to power a led for a project on one of my guitars. I'm not sure what kind of resistor I would need. On hand I have a 33ohm and 1m resistors. The led is a 5mm cylinder with an inward cone on top. The led ranges from red, blue, yellow, and green in different patterns. It came from a light up snow flake and the original power source are 3 LR44 button batteries. I'm not sure what rating the led is, since I didn't see anything on the packaging. The schematic is just the same as the original setup minus the 9v(LR44s) and the switch(little slider). Thanks in advance for the help!

Hey everyone I was hoping someone could help me with a project that I'm working on. I'm relatively inexperienced with electronics so this might just be a simple solution, but here it goes. I have a 4.8V, .9A power source and I would like to connect the power source, a toggle switch, a LED, and a USB port in series. A pretty simple idea. I don't know too much about LEDs, but I do know that you have to use a resistor with it. And I've heard that the LED and resistor have to have a voltage drop equal to the voltage of the power source. My main question is this though: how can I use the LED along with the USB port? Will there be enough voltage left for the USB after the LED is lit? Thanks for any advice!

I recently started playing a game called Warframe and in this game, they have little "sentinels" that you can make to help shoot enemies. I decided I wanted to build my favorite which is basically a cube that is equipped with a mini-gun, the Dethcube. The only problem is, I can't seem to come up with any ideas on how to make it hover above my shoulder. Anybody got any ideas on how I could make it float?

Using an Arduino UNO, an MP3 shield(and 2 speakers) and a breadboard, can I have 10 white LED's, a potentiometer to control brightness, a potentiometer to control flashing of the LED's, a stepper motor or a servo, 2 buttons for the motor(left right), and finally 3 buttons(play, stop, skip) for the mp3 plus a volume knob. Is this possible, or will I need more that one Arduino? Speakers: Input interface: 3.5mm Stereo Jack Input sensitivity: 650mV ± 50mV Degree of distortion: ≤ 5% Speaker impedance: 4ohm Frequency range: 85Hz ~ 20kHz SNR ≥ 80 dB Output power: 3W * 2 Rated voltage: DC 5V /1000mA

I am looking to create an array of LED's attached to switches. There will be 14 LED's in total. 3 green LED's attached to a single 2-way switch, 8 red LED's attached in pairs to 4 3-way switches, and 3 white LED's attached to 3 more 2-way switches (3 seperate 1 switch:1 LED set ups. Nothing wierd or fancy there). I'd like it all to run off a single power source, light powered would be best, but if that turns out to be too complicated I'll settle for battery powered. My questions are: What kind of power source will I need to use? How is the best way to wire it? and What sort of equipment will I need (resistors, capacitors, etc)?

Hello all, thought id share my progress of my 97' VW Golf mk3 VR6 2.8 to create some discussion and VAG banter. I brought her completly standard and wanted to build a real sleeper for road use and track use that is fast, practical for everyday use and safe for the family. When I got her back in 2009 she was a standard vr6 nothing really special just a well looked after example Firstly I gave her a good clean inside and out along with a service.......and by clean i mean really cleaning, shampoo the carpet, treat the leather, clean out the heater units, remove and shampoo the roof lining, polish and resin the paint, de greese and steam clean the engine bay to name some of the bits ive done. The result was a very clean base "template" Once all was clean and I could see areas for imporvement I began the work, replacing all the bushes, front and rear lower arms, brake lines, discs, calipers, exhaust were the easy steps When it came to the engine itself I did not want to mess about with it too much just improve the BHP and general running of the car as 174bhp from a 2.8 VR6 is shocking. So removed the engine and re conditioned the gearbox and clutch. While this was out I thought it best to also do the pull chain not a big job but much easier with everything out, once back in I still was not finished.... After giving the engine a full service with new plugs, leads, coil pack, oil change, rocker cover, inlet manifold, seals, upgraded air filter I decided to get the car chipped to see what BHP could be pulled out of her. Happy to say with all that work she was running on the first dyno 192bhp a massive improvement from standard 174bhp and all that from just replacing and upgrading some standard old parts with more expensive performance parts. Once the Chip was installed and the guys at the tuning store had done their works she was happily chucking out 216.4BHP With that I was more than happy and the work put in over the 6month period really showed. I then decided to have all but bumpers colour coded and did a few minor tweeks to the exterious to make her a clean standard example... I will add a full list of specs and work done soon, enjoy the pics feedback welcome
