Please help me about my thesis.

Hello. I'm currently taking an Electronics course. I have a thesis. So here's my thesis idea.The purpose of my thesis is for children's safety. A child will have to wear a watch wherein it will send off signals continuously and when the receiver which is inside an extension receives the signals emitted from the child's watch it will trigger the outlet to switch off then the appliances plugged in that extension will be off. As for the extension I'm gonna put a relay circuit inside an extension wherein any appliances could be plugged in. My problem is what transmitter and receiver am I gonna use to trigger the circuit to switch off? Should I use Bluetooth? But it doesn't auto-connect as far as I know. Can I use Zigbee shield? Does it have transmitter and receiver? What microcontroller should I use? Please help me. :( Thanks in advance!

Thesis project engineering

Hello everyone, i'm in my fifth year industrial science, and next year I need to accomplish a thesis project. At the end of this year I need to find an interesting project, something that has to do with fysics, math, mechanics and electronics. of course its almost impossible to have a project that has to do with all of those subjects so you can leave some out. Has anyone some bright ideas? I've been looking but I have not found what I need yet.

Working on my Masters Thesis

Hello! I’m currently working on my Masters at Simon Fraser University, in the SIAT department. As part of my graduate research, I’m looking into the structure, content, and presentation of DIY tutorials. To do this, I’ve taken one very well-known DIY tutorial, and converted it into twelve unique formats. I’m hoping to have as many experienced DIY tutorial authors look though the modified tutorials I’ve made; then try imagining using them as formats for presenting projects they’ve made in the past, or are thinking of making in the future; and once that’s done, getting their feedback. If you’re interested in participating, I’ll give you access to the tutorials for a week, so you can look though them and get acquainted with each. At the end of the week, I will send you an online form with a couple of questions relating to your preferences, opinions, and overall thoughts of those tutorials. If you’re interested or have any questions please feel free to ask. Thank you very much! -Matthew

Advice for hydraulic master thesis.

Hello, I’m a civil engineering student and I’ve always had a special interest for electronics, sensors, and arduinos. I’m finishing my degree for which I have to develop a thesis. After some research and based on some articles, I proposed to my hydraulics Professor to monitor the solids transportation (at the bottom of a river) using a hydrophone. This idea consists on measuring the intensity/quantity of sediments (like rocks and muds) passing through a certain spot. These measurements are made using a hydrophone put underneath a seel plate – when the sediments pass beneath this plate they create impulses or frequencies, which will then be analyzed. What I would like to know is the best way to capture these frequencies through the hydrophone – mobile recorder, daw, arduino? I intend to connect the hydrophone to the computer, either through the arduino or through a sound plaque, but I’m afraid these solutions are more prone to the appearance of noise. The frequency range to analyze is between 10Hz and 30kHz. Will it be a good solution to connect the hydrophone to the arduino? Another issue in my mind is the handling of the data gathered – should I use excel, matlab or python? Thanks, Carlos Esteves

Physical Space Installation Game

Looking for people who are interested in helping out on the electrical engineering side and/or set design of a installation game. Various people in the industry (theme parks and video games) should stop by during the exhibition and credit will be provided. On the electrical side it would be helping out with networking of Arduino boards to run each "gag" and be linked into a show control. On the set design side - help with the set design of the piece, lighting, and construction. The installation will take 3 players and have them "break into" a vault with various high tech security (lasers, pressure sensors, computers needing to be hacked, etc). Other examples of this type of work would be "The Tomb" and "Operation Spy" by 5wits, La Fuga by Negone (in Spain), interactive haunted houses, and theme park attractions. Message me if you have any questions. Thanks!

WANTED-Pattern Testers for Thesis Project: Knit Lamp Post

Hi everyone, My name is Kim and I’m a senior at MIT.  This semester, I will be working toward completing my thesis project, and I could really use some help to do so.  I’m an avid knitter who has spent the last four years studying architecture, and I plan to bring my two passions together in the thesis which I am preparing.  In a nutshell, I will be designing lamp posts which will be completely self-sufficient.  They can exist off of the electrical grid of a city or town and will be constructed from knit fabric.  Thus, they can be constructed by a few members of a community, allowing them to take action to solve problems in their own neighborhoods rather than waiting for the government fix them.   My project is about community empowerment and giving the power of construction and repair to those who need it most.  If you’re at all interested in learning more about my project, you can message me or read more of my thesis proposal at the link which follows this post (I promise, it makes more sense than what I just typed out here).  I could really use some help in completing this project, though.  I need to find a few willing people or groups of people who would like to knit a lamp post for themselves or their communities.  I need people to test my pattern to see if it actually works.  If you’re interested, please e-mail me at kimennel [at] gmail [dot] com, or message me here.  If you want to help, I’ll be sending out a package to you with materials, knitting needles, and instructions in a couple of months.  It’ll be free of charge for you, and all I ask in return is a bit of feedback about the pattern and some photos of the construction process and final product.  So, if you want a free lamp post, please please please, let me know.  Thanks guys :) The link to my proposal is here: http://www.mennels.com/kimennel/Thesis%20Proposal.pdf

Maker Collaboration with Companies, in Prototyping Activities in Product Development | Survey, Thesis

I would greatly appreciate it if you could find the time to fill in my survey, here: https://forms.gle/YHHbEzEy9NGQVFJGAI'm studying my masters, in Design and Innovation, at The Technical University of Denmark. The thesis project is to develop a prototyping tool to help companies engage with the maker movement, in their prototyping activities. I'm trying to identify how makers can benefit companies in collaboration and vise versa. To put it bluntly, we know makers (and I include myself as a 'maker') are much better at producing low cost solutions to novel problems using limited resources, than most companies. I'm trying to make a tool which will help facilitate collaboration and co-design between product developers and makers, in a way that's mutually beneficial. The survey should only take 10-15 minutes maximum. I would also appreciate it if you could share it among your various maker communities and friends who call themselves makers! Many many thanks in advance.

Grad Thesis survey questions - Please send me your answers!!

Hello! I am a graduate student at Pratt institute in Brooklyn, NY. I am currently working on my masters thesis in Industrial Design. My subject so far is: Hacking, 'making' and craft as a form of recycling and reusing - product life extension by the user. Basically, I am interested in keeping potentially valuable materials out of the ever-growing rubbish pile. Instructables were part of the inspiration for this thesis, and I am wondering if you would take a couple minutes of your valuable time to answer these questions for me. The questions might be a bit cursory or vague so your answers can be the same - I am also interested in the differing levels of humor involved in the motivation, process and results of the hacker and their 'products'. I would really appreciate your input, and I want to thank you for your time in advance! Disclaimer: None of this information will be used for anything other than my written thesis and 15min oral presentation in April (Which you can view, let me know if you want to attend!) - but, please do not divulge any information you dont feel comfortable sharing with my thesis class - use a good false name if you like, (or I can make one up for you) but please be as accurate as you can with all questions. Thanks! So here are some questions! 1 - Who are you (name), and what do you 'do'? How do your friends describe you? (ie- day job, side projects, labor of love, for fun, etc) 2 - What do you carry with you at all times? (keys, phone, wallet, knife, etc) Anything you consider 'unusual'? 3 - Are you a 'gadget person', do you need to have the new thing (iPhone or other smartphone, Macbook Air/EEEpc, etc)? What and when was the last computer purchase? Mac, Win (XP or Vista?) or Linux/other? 4 - What was (were) the last modification(s) you did? (electronic, soft, other) 5 - Do you recycle? (Paper, plastic, etc) How do you dispose of old electronics? 6 - Do you ever take other peoples, or buy old electronics, to hack? What was the last you did that with? 7 - With the popularity of publications like MAKE, CRAFT, ReadyMade - and websites and blogs like Instructables; are we are witnessing a new craft movement? (please explain) 8 - Can you explain the history of this movement (if you feel it exists)? What is your favorite part of the increased popularity of making, hacking and modifying? What do you think is the future of this movement? (looking near or far) 9 - How do think this change will affect Industrial Design, and the design/concept of personal electronics, shoes, tableware, furniture, etc? 10 - Is there a device, object, service, product, etc that you dream about, wish existed, half-joke about with friends? Is there a problem you feel strongly about? Something you feel is overlooked? 11 - Can you recommend anyone, or any resources you feel could be really useful in thinking about this topic? Alright! You are done! Thank you so much for you indulgent participation, I appreciate it so much! -Crankola-

Can you insulate the primary coil of a Tesla coil?

Hello,    I am trying to build a tesla coil using a new design relating to a thesis paper I am working on. Due to spacial restraints my primary coil will be close to the secondary coil. I know I have seen others use insulated braided copper wire as their primary. I want to stay with 1/4" copper tubing if at all possible so I wanted to ask what affects it would have if I used heat shrink tubing on the copper tubing. I am aware the higher frequency voltage runs along the skin of the tubing since that is least resistive at that point. A for the power and caps I am using the following: three NSTs of which two are 15kv @ 30 miliamps and one 12kv @ 30 miliamps, 13 CD 2000VDC @ .15nf caps on each 15kv NST and 10 of the same caps on the 12kv NST. The spark gap is static for now.  I want to prevent arching as much as possible in the small space. Any advice is greatly appreciated. Some of the information relating to the thesis paper I cannot release due to a serious concern of being scooped before publication.  Thank you. :)

Archaeology Student needs help with 3D scanning and printing

Hi Guys and Girls, first time posting like this so i hope this is in the right place, and if it is i can get some help. I'm currently studying Applied Archaeology, in the Institute of Technology Sligo, in Ireland, I'm in my fourth and final year and as part of this I have to research and write a thesis. The topic I am planning on doing involves 3D scanning, and if everything goes to plan, it will turn out great, and is something no one has done before in Irish archaeology, Ok so here’s the thing. It is still early days, I haven’t even decided on the title or gotten a chance to experiment with the scanner, and I am relatively new to 3D imaging and all that it involves. But as part of the overall concept of my thesis I would like to haves some of these scans print using as many of the various different methods of 3D printing as I can. This is so I can compare and analysis there suitability. This is where I hit a wall and I hope someone can help. There aren’t many companies that do 3D printing in Ireland and those that do usually deal with medium to large company’s and thus are way out of my price range. Edit: 21.09.2011 Ok after a doing a boat load more reserch I have been able to pick three methods of 3D printing I would like to use: 1. Fused Deposition Modeling using the, RepRap and MakerBot. 2. Laminated Object Manufacturing. 3. Stereolithography. If any of you out there have an interest in Archaeology and can offer advice on 3D scanning, image editing, has access to a 3D printer or are lucky enough to own one of these machines, and are willing to help me out I would be extremely grateful. I am more than willing to contribute what I can to the cost of raw material, cover the postage to Ireland and of course give massive amounts of praise and acknowledgement to all those that have helped, when I’m writing my thesis. Many Thanks Michael Michaelfeeney01@gmail.com

Monitoring a baby with an Arduino and some sensors. Ideas?

Hi dear lads and gals, I'm working on my Electrical Engineering bachelors thesis and it evolved into something that I couldn't have foreseen. I'm trying to build a baby monitoring package that would involve 3 major things; Baby's -Temperature changes -Breathings -Positions in the crib (in or out) and all these should be controlled through a mobile app. I have a couple of challenges. First of all there can't be wires all around the place to detect these changes and I'm not quite lost about how the package would be. I've experimented on a waterproof ds18b20 temperature sensor (got the temperature saved on a web server) and a flex sensor (thought of planting it under the crib) so far. For the breathings I thought of using a microphone but didn't really get my hands around that. What better sensor there are that would simplify the process? What should this package consist of?

Multiple Circuits to one power source

I am working on finalizing a circuit bent sculpture I've done for my undergrad thesis. I have three circuit bent items, each with it's own battery source within the sculpture. Here is my dilemma: normally I plug in the batteries when I show it to someone, then promptly take them out, but for my gallery show, the sculpture will be turned on for an extended period of time each day, in my absence. What I would like to do is connect all circuits to one battery source or AC power. After that I can add a switch so that the gallery attendant can turn in on/off as needed. I am looking for any tips on how to do this. As of now, one runs on a 4-AA pack, one on a 2-AA pack, and the last on a 9-volt. Adding these together I am getting 18V(?) and I have an old laptop adaptor that has an output of 18.5 volts. I have a video of the piece functioning if anyone is interested. Thanks for your help (in advance).

Upcoming contest for teachers

Remember how there's a new channel for explicitly educational content? That's not all we're doing for teachers. We will also be running a contest specifically for educators*, so fire up those school-provided laptops and start thinking about some awesome projects you might be able to share with the Instructables community. If you'd like to win a MacBook Air, a class set of Instructables pro memberships, and other unnamed secret prizes, you just need to enter an academic Instructable or guide. We'd love to have anything academic, from elementary school art projects like construction paper masks to a university-level electrophoresis demonstration.  In this contest, we will also be accepting guides for the first time along with the usual step-by-step, photo, and video fare. Curate a collection of teaching projects by subject, age level, or some other unifying trait. (Kind of like https://www.instructables.com/id/Made-in-Your-Mind-Instructables-The-Childrens-/) Hold off on posting until... Contest starts December 4th.  *Just because you don't have a .edu email address doesn't mean you won't have something to contribute. If you can teach something (factoring, researching a thesis, throwing a pot, or modifying shutter speeds for low-light situations, whatever), we want you to share it.

Controlling anaerobic digesters with arduino

Hi I am new on the Arduino scene and I am trying to build eight anaerobic digester tanks to conduct experiments for my thesis in engineering. The setup will look as follows: -Arduino mega -Arduino motor shield R3 -Two motor stirring the digester at different RPMs. Motors will run at 12 V and around 0.5-1 A. -The motor shield will use the wall jack as power supply via an AC-DC adapter. -Biogas volume measuring device (tipping sensor) -Aquaria air pump to supply Hydrogen Sulphite consuming bacteria with oxygen. This will be controlled with a relay and the volume measuring device. -The pump will use the wall jack as power supply -Temperature sensors DS18B20. -Immersion heater controlled by the temperature sensor and a relay. The digester is supposed to be kept at 37°. Everything will be logged but I haven’t decided if I will connect a Ethernet shield or if I should log on a SD card. I think that I can manage to build it but I have some questions (a lot) but will just post some and post more later. The experiments will run for 4-6 months how will the Arduino, shield and relays handle being on for that long? Do I need something with higher quality? (It would suck to burn down the university) Any spontaneous thoughts that I should know or that could help me?

The vehicle has a Wild Thumper arduino board, Dension WIRC with 2 camcorders and a wifi stick, 2 LED's, a servo motor and 2 DSMP420 motors with a power of 41W. Thanks to my thesis, I started to have interest for arduino. And so I bought a lot of arduino products like the arduino UNO. And thanks to the opensource of arduino I learned a lot of arduino and tryed a lot of projects. So that’s why I'm also putting my project online. It isn't finished because I still have some problems with the charging of the battery's. I use 10x1.2V battery's with 4.5 Ah in series. And the Wild Thumper stops too soon charging. But I'm working on that. :D It's controlled with the WIRC app that connects with the Dension through wifi, which sends signals to the Wild Thumper. These signals controls the motor's and the LED's. The servo motor is directly connected to the Dension. The vehicle will later be used by the Company Cofely to ride in ducts and inspect cables or even take something with the gripper in unreachable places. We are doing a competition with our project. So could you please like this page https://www.facebook.com/wattsup.nl and vote for our project http://woobox.com/8uv6bi/vote/for/2991407. Make sure that the checkbox is green! :D Thank you very much You can follow us on fb www.facebook.com/Inspectiewagen

Small Home/ Small Apartment Work Bench

Hello!  I am a senior industrial design student and I am currently working on my senior thesis, which is to design a workbench or work station for DIY people who live in small apartments or small homes with no dedicated rooms to build in. I am looking for ideas/experiences/input from DIY people who have experienced this issue. If you have any ideas or thoughts on this type of work bench design please post them here. More importantly please answer the interview questions I have posted below. The more information I can collect from potential users of this type of workbench, the better all-around design I can come up with for the final product. I am really looking forward to hearing for everyone. Thank you for you help! 1. When you need to build or make something in your home, in what space do you build/make? (Living room, bedroom, office, outside, etc.) 2. What type of surface do you build on? (Worktable, desk, kitchen table, etc.) 3. What types of projects do you build or make? (Home improvement, decoration, storage, furniture, etc.) 4. What tools do you own? 5. Which of those tools are most useful in your builds? 6. How do you store your tools? 7. What issues do you encounter trying to build in your small space? 8. Are there any specific ideas you have that would make your building/make experience better in your small space?

Open Call : DIY Collab Teams

I'm working on my MFA for Design & Tech at Parsons in New York, and my thesis is on DIY collaboration teams. I propose a set of open source knowledge collaborations. The benefit will show when our innovations make it to the products we use daily. I envision the forum section as a discussion area, with the instruction set side being more of a workspace. I will also create a wiki to act as a collection of the innovations / knowledge gained from these projects. Why is this interesting? This community has a ton of potential, with users that have specialized skills in almost any industrial field. We already modify or create things as we see necessary, and teach each other what we learned in the process. I believe that if we could collaborate on focused topics there is no limit to the innovation we could produce. It doesn't make sense for product users to be left out of the design process. This is not a new idea, some of the best innovations and discoveries were made by users, not corporations. One of the benefits is that nobody would own the rights to any portion of the project, so it leaves open the possibility for further innovation from interested parties. The main theme here is interest; innovation comes from a community like ours where people are actually interested in what they do. The focus of my research is about the nature of participation within these mini-communities, however you probably know that I will not be able to just sit aside and observe. So within the next week I will be jumping in on a topic that I can contribute to. As for other topics that are proposed, I am more than happy to do whatever I can to help, and I will hook up with the teams to observe the collaborations. Anyone interested, and if so, what topic would you like to collaborate on?

Toyota Will Offer a Plug-In Hybrid by 2010

If you make it, they will come. Or something.CalCars, the California Cars Initiative, has not only been campaigning for plug-in hybrid vehicles, they were the first to build a plug-in Toyota Prius. CalCars longstanding, and really quite simple, thesis is that plug-in hybrids can achieve 100+ MPG using today's technology:We promote plug-in hybrids (PHEVs). PHEVs are like regular hybrids but with larger batteries and the ability to re-charge from a standard outlet (mostly at night). They're the best of both worlds: local travel is electric, and you always have a gas-tank backup. More details here.Toyota seems to have finally received the message, now pledging to offer a plug-in hybrid by 2010: Toyota Will Offer a Plug-In Hybrid by 2010 (NYT). From the article:DETROIT -- The Toyota Motor Corporation, which leads the world's automakers in sales of hybrid-electric vehicles, announced Sunday night that it would build its first plug-in hybrid by 2010.The move puts Toyota in direct competition with General Motors, which has announced plans to sell its own plug-in hybrid vehicle, the Chevrolet Volt, sometime around 2010.Katsuaki Watanabe, the president of Toyota, announced the company's plans at the Detroit auto show as part of a series of environmental steps.Mr. Watanabe said Toyota, best known for its Prius hybrid car, would develop a fleet of plug-in hybrids that run on lithium-ion batteries, instead of the nickel-metal hydride batteries that power the Prius and other Toyota models.Plug-in hybrids differ from the current hybrid vehicles in that they can be recharged externally, from an ordinary power outlet. In a conventional hybrid the battery is recharged from power generated by its wheels.Mr. Watanabe said the lithium-ion fleet would be made available first to Toyota's commercial customers around the world, like government agencies and corporations, including some in the United States. He did not say when they would be available to consumers.Another case of hackers' solutions becoming mainstream? Definitely!

Toy-Story 3 lots-o huggin bear conspiracy.

So i finally watched Toy Story3.(which happens to be epic) But I happend to relate lots-o huggin bear to adolf hitler....Why?you might be wondering. Well here's my list of thing that support my thesis. Also this is sorta crazy..maybe im just over thinking this but it does all make sense. 1-The biggest indicator is the line "Things were fine until lots-o came along. and he made a pyramid and put him self at the top of it!" which is what hitler did in the 1930's by making germany a dictatorship. 2-Another thing i noticed is how:Big baby,the rock moster,and the bug. Were alot like the SS by doing lots-o's bidding no matter what. 3-SPOILER-Near the end of the movie when they get past the trash grinding thing. And lots-o was gonna hit the stop button. He didn't and the toys he didn't like(woody,buzz,etc.) were going to end up in the trash incinerator. Which made me think of the mass burnings of jew's during the holocaust just because hitler didn't like them. 4-I also related to quote by pricklepants(the clown)"Sunnyside is a place of ruin and despair, ruled by an evil bear who smells of strawberries!" To how the concentration are usually described in history books/storys. Also i related how the evil toys(hitler,SS)lived well in the butterfly room.versus how poor the good toys(jew's) were treated awfully in the catepillar room. And how they showed the kids doing all sorts of crazy things to buzz and the gang. Well thats all i have now but i plan on writing some stuff down the next time i watch it. So expect more...also i know this is a very far out there conspiracy but if you've seen the movie then perhaps you'll agree.

Religion/Theology Topic (I couldn't think of a good name)

I've had this idea for a couple months now, and I thought I should share it with you guys. I have been interested in science for as long as I can remember (at the expense of my social life), and have always been an atheist. It has always made sense to me, and theism (opposite of atheism, the a is important!) never really has, other than the basic human will to believe in something that keeps order in the universe.But this forum post is not about debating between atheism and theism. Many of us on Instructables excercise our knowledge of the world, and our will to spread it to others. I have partaken in this as well, posting my fill of comments trying to explain why atheism makes sense. But I have recently ceased to do this, and not just because arguing becomes very tiresome, very quickly.Probably the greatest reason why most people believe in a god (or gods) is because it gives them hope; someone to look up to for wisdom and strength in times of need, and a justification for being humble and small in the big wide world. Everyone knows hope is important. I'm not the most hopeful person. Being an atheist does not help this. This is why I have stopped my "atheist trolling". If everyone were like me, spending endless hours of my life just thinking, and coming to conclusions that I should not have come to until I am old. and going insane, and disconnecting from society, the world would not be a very pleasant place. It probably would not be very good if everyone were theists either.I guess I should just say what I've meant to say throughout this whole thing: ignorance is bliss. Many theists are very happy and content with life because of religion. So after this whole post, here is my thesis which I wrote down after going (obviously) off track about halfway through writing this post. God dammit, I need a word limit.I do not bother people about atheism any more because it gives people hope and keeps people sane, which keeps the world in order.

Google Celebrates 57 Years of a Great Invention

Google's new picture depicts a barcode saying "Google" to celebrate 57 years of the bar code. For a brief history from Wikipedia about the barcode;"In 1932 business student Wallace Flint of Harvard Business School wrote a thesis promoting an "automated grocery store" using punch cards, which customers would hand to a clerk, who would load them into a reader, causing flow racks to deliver the desired products, after which an itemized bill would automatically be produced. In spite of its promise, punch card systems were expensive, and the country was in the midst of the Great Depression, and the idea was never implemented.In 1948 Bernard Silver (1924 - 1962), a graduate student at Drexel Institute of Technology in Philadelphia, overheard the president of a local food chain asking one of the deans to research a system to automatically read product information during checkout. Silver told his friends Norman Joseph Woodland (1921-?) and Jordin Johanson about the request, and the three started working on a variety of systems. Their first working system used ultraviolet ink, but this proved to fade and was fairly expensive.Convinced that the system was workable with further development, Woodland quit his position at Drexel, moved into his father's apartment in Florida, and continued working on the system. His next inspiration came from Morse code, and he formed his first barcode from sand on the beach when "I just extended the dots and dashes downwards and made narrow lines and wide lines out of them." To read them, he adapted technology from optical soundtracks in movies, using a 500-watt light bulb shining through the paper onto an RCA935 photomultiplier tube (from a movie projector) on the far side. He later decided that the system would work better if it were printed as a circle instead of a line, allowing it to be scanned in any direction.On 20 October 1949 they filed a patent application for "Classifying Apparatus and Method", in which they described both the linear and bullseye printing patterns, as well as the mechanical and electronic systems needed to read the code. The patent was issued on 7 October 1952 as US Patent 2,612,994. In 1951 Woodland and Johanson moved to IBM and continually tried to interest IBM in developing the system. The company eventually commissioned a report on the idea, which concluded that it was both feasible and interesting, but that processing the resulting information would require equipment that was some time off in the future.In 1952 Philco purchased their patent, and then sold it to RCA the same year. In 1962 Silver died in a car accident."Full story about Google's choice of picture here here.

I want to make an object which can register button presses and sent the time being pressed to a webplatform

I am a master student in Belgium doing Communication and Multimedia Design (Interaction)For my master thesis I am trying to find a method of supporting children whose parents go through a divorce. I am trying to do this by making a physical object (cube for now) and combining it with a digital (web)interface.The main goal is to have the physical compact and portable object (a cube with buttons for now) being used by the kid and he/she being able to press a button related to a situation or emotion they may encounter (read: portable diary). So wherever he/she is, they can use the object to express what they encounter (a button related to self image, a button related to denial, ...). This input then goes to a digital platform where parents and/or a psychiatrist can look at when and what the child went through and use that info to know which problems they are and start a conversation about it in a way that the child does not have to be upfront about it.I got most of my theory figured out and went to psychologists myself to see what these processes are, the next step is to now start making a prototype. This is where I have my difficulties and hope to find some help in this great creative community. I have a bit of experience with Arduino and have access to a lab with lasercutters, 3D printing, ...So the main technical questions are as follows:Which material can I use to make a compact enduring cube?What can I use to register button presses?How can I make this object so it can be turned on and off (so buttons don't accidentaly get pressed)?What kind of buttons can I use/make?How can I integrate a indicator light for it being on or off?How can I send the data collected?How can I collect and organise the data on the digital (web)platform?And how can I make this all compact so it fits in a cube of about 6 by 6 cm?I know I may be asking a lot and I don't expect you to answer everything or do it all for me, of course I will keep doing whatever I can while this post is here. But any input/feedback is welcome here, since I just started doing this first prototype, many options and suggestions can still be implemented so if you have any knowledge of what I try to make (for example sending data over long distances OR other suggestions on what object is could be) FEEL FREE TO LET ME KNOW :DThank you in advance! I hope to hear anything at all :D

Design Changes on Instructables

As you've noticed, we've been making some design changes to Instructables.  We're trying to accomplish a number of things including making it easier to find content you're interested in, creating more compelling products for advertisers, and supporting and growing what we've already built.  Here, I'll share the details around some specific design changes. One of my big goals for 2010 is to increase our direct visitors.  A direct visitor might type our URL into their browser, click on a link in a newsletter, come to the site from one of their bookmarks, or search for a phrase that includes "Instructables".  Other types of visitors include searchers, who come to the site from phrases such as "sweet potato fries" but aren't specifically trying to reach Instructables.com, and visitors from blogs or news portals.  My thesis is that more and more brand advertisers will want to reach our true community, and not people who are just passing by.  A pretty good proxy for our true community is direct visitors, and we've already seen the savviest advertisers try to reach only that community by advertising exclusively on our homepage (the recent Apple campaigns, for example).  To grow our business and ensure that Instructables thrives, it's important that we have great opportunities for advertisers, and a stronger community means more great Instructables and more intelligent people seeing and commenting on your Instructables. To this end, we've been working to increase the likelihood that someone will go deeper into our content, and remember to come back in the future.  Said another way, we want that sweet potato fries Google search to introduce someone to Instructables, and then have them think, "wow this site is amazing, I'll bookmark it, sign up for the newsletter, come back, etc..."  Some of the most dramatic changes are on the homepage and channel homepages.   On the homepage, we've removed the intro text from the links to Instructables.  By making the homepage less cluttered with words, I was hoping to increase the number of people clicking on an Instructable.  Also, I felt that the beginning of the intro text didn't contribute much to my understanding of the Instructable, and often it was no more than a repetition of the title (and at worse a note about how it was someone's first...).  Removing text to increase engagement might seem counter-intuitive, but with too much going on, visitors sometimes just leave rather than decide what to click on.  So far, clicks from the homepage are flat or slightly up, so this change hasn't had a negative effect on deepening visits, and may over time move us in a positive direction.  On the channel homepages, we've drastically changed the layout to be more blog-like.  My theory here was to give people a format they were more familiar with from elsewhere on the web, and results have been dramatic.  The exit-rates (the percentage of visitors that leave Instructables from a particular page) on our channel homepages have been cut in half.  For example, the exit-rate on the home channel homepage has dropped from 12% to 4.5%.  This is really good!  To me, this indicates that on the channel homepages we're giving visitors more compelling content, and they are more likely to dig into that content. In support of our efforts to deepen visits, we've been doing similar smaller changes all over the site. Most of these are based on our traffic and click analysis, and if my theories are wrong, we change back or try something else.  One particular change that has generated concern is the removal of the Answers link from the header.  This has nothing to do with our support of Answers in general -- it's based on data.  That link was almost completely unused.  Coming again from the perspective of making a slightly cleaner look, we removed it.  As the link wasn't generating any clicks, traffic to Answers has been unaffected.  In fact, as we're highlighting specific answers on the channel homepages, traffic to the Answers section is actually up 7% since we removed the link:  from Feb. 1 - 18 answers did an average of 11.1 K pageviews per day; from Feb. 19 - 28 it's done 11.9 K pageviews per day.  Perhaps that's noise in the data, but removing the link certainly hasn't been the end of answers, and the trend since the change is positive. So, we do rearrange the furniture from time to time, but it's never without reason.  We're always trying to make Instructables better.  We've messed up in the past, and we'll surely mess up in the future; but I think this is good, because if we're not reaching and striving a little bit beyond our comfort zone, we're not learning and improving.
