Kevin Lau shared: “Ginbo. This is the prototype for my environmental sensor device idea.The data will be uploaded to internet by the communication with mobile phone.Imagining you can access the data(data will be designed as a visual character)from the device you follow. Like you can know where is raining at this moment. The LED matrix is set as an output. It can be a data display or emotion express. I put it on the top of umbrella because of thinking umbrella is a good partner to go as well as explain my thinking about design hugs technologies.” (read more)

Nicholas Seward shared: “Wally is growing up fast. Too bad I won’t be at home for the next two weeks. I am going to throw some steppers on him and put him through some first moves as soon as I get back.” (read more)


Pete Weller shared: “Well here it is. I did my best not quite done.” (read more)


Heather Solvers shared: “Mod Melts: I’ve been excited for this “resin-like” material since first hearing about in January. I thought, I could make wee robot parts, hearts, hands, etc. The material just doesn’t seem to work with thick molds. I think the company only wants you to use their molds which are ultra thin and your finale product will be ‘rustic’. More crafty less artsy. It takes an entire stick to make one wee robot face brooch. Still love the mold making stuff ComposiMold but the melts are done for now. I think, I meant to only hand sculpt each one of my robots. Still this experiment in molding and casting has ended a lot better than my last attempt years ago which ruined a kitchen corner and ended in tears.” (read more)


Mano Biletsky shared: “Solved! Overlapping objects in processing…. I made this gui interface and had problems (many others do too) with dropdown lists being overlapped by buttons or other objects.” (for the solution, read here!)


phenoptix shared: “Any Ingressers on here? Files on thingiverse to make your own key fobs. We cut some of these for Daniel Gray to take to an Ingress meeting. They went down a storm so we’ve put them in our store for now and made the files available for everyone to use. ” (read more)

Jaidyn Edwards shared: “This is for all those Arduino people out there, who I’m sure, do the same stupid things I do. 🙂 Hope you enjoy.” (read more)


Kurtis Kopf shared: “Update on the Arduino Mega shield for rocketry: I have one all assembled and working, sans the gyroscope. I think I fried the first one I tried to mount… overcooked at 300C when the recommended soldering temp is 250C… whoops. Ordered some lower temp solder and will attempt to remount a replacement soon. Code and board design are here!” (read more)

Sandro Perini shared: “MPU-6050 Accelerometer test” (read more)


Jude Pullen shared: “Hello, I just created a new Design Modeling project which demonstrates basic electronic hacking skills with Industrial Design prototyping skills. I call it the ‘Ergo Mouse’, and really appreciate seeing what you might come up with, should you be inspired…” (read more)

Bruno Pedro shared a video from Mini Maker Faire Barcelona. (read more)

james wolf shared: “I figured out how to get my DIY Headtracking setup to work with the Google Streetview API, so when I look left it looks left. Its like real-world virtual reality. When I look from one side of the screen to the other I do a full 180 degree sweep. If I need to turn more then that I can turn just my body by hitting the left or right arrows (keyboard)” (read more)

Nikolaus Gradwohl shared: “Today I finished the interface module for my raspberry pi based retro car radio. The module interfaces the buttons, the variable resistor and a RGB-led using an ATMega 328p running an arduino firmware. This is my day 30 project for 30daysOfCreativity but I think I will need to extend my 30 days a bit so I can finish this project :-)” (read more)


Jeremy Cook shared: “Finally able to stand on its own! Now if it can be made to walk…” (read more)


Jay Doscher shared: “Almost done with the #raspberrypi solar project. I need to button it up and fabricate the solar panel mount. The howto should be ready by next week!” (read more)

Andrew Festa shared: “In the process of making a quadrocopter, and am working on designing and building the frame right now. So far, I have the basic frame made out of wood, but plan on having the final be out of carbon fiber. Does anyone know if I can spray the plywood of the frame I have with spray enamel to make it so that I can use what I have as a mold for the carbon fiber?” (read more)


jon sanford shared: “The tree that used to shade in the summer is not thriving because of the drought. so the design flaw is revealed . It has been impossible to work in there this summer.” (read more)


Pascal König shared his Arduino Jukebox Prototype. (read more: content is in German)


Sam Harrison shared: “Don’t worry, this foam board prototype isn’t supposed to function. I designed it purely for aesthetics to see how it looks and how the actual Acrylic version will fit together. This foam board is around 3mm so it makes a perfect prototype if you’re past the wood stage but not quite at the acrylic stage yet. When looking at the motor housing I noticed the brackets didnt quite align with the body which pushed the top wheel out much further than I had wanted (mis-calculation on my part). I’ll probably alter this design a fair amount before moving on to acrylic just smooth some corners and strengthen the whole body. Keep checking in my acrylic model will be ready soon.” (read more)


Steve Anderson shared: “A pleasingly dangerous lamp. (Cold cathode tube from the scanner I found the lens in before – will find something to do with it one day.)” (read more)

Community Projects from the Adafruit Blog


Scott Alan McClurg shared: “This picture was created using my father’s Raspberry Pi – and his pedal power. I created the image file and took the photos. He built the Pi, the LED rig, the bicycle mount, and did all the pedaling. He got tired, I got bitten by a swarm of mosquitoes, but I think the results were worth it.” (read more)


Erik Russell shared: “I have been excited about playing around with a Raspberry PI and I had some free time so I purchased a unit. I bought a Raspberry PI model B along with some accessories from Adafruit Industries. Adafruit tests the accessories with the Raspberry PI so it eliminates the hunting for compatible accessories. My intent for the NAS was to create a low cost / low power device to store a backup of digital pictures.” (read more)

Charles Mangin shared: “This is a quick demonstration of how to connect a Raspberry Pi to the built-in keyboard of a vintage Apple II (the Apple //c) with the help of the RetroConnector Shield. The RetroConnector is a shield for the PJRC Teensy++ Arduino clone that acts as a USB HID device, translating keystrokes on the //c keyboard into something a modern computer (PC, Mac, Raspberry Pi) can understand.” (read more)


PiQContinuum shared: “Ever since I first heard about the project, I was very excited to buy and play around with a Raspberry Pi. I wanted to come up with a fun project utilizing the Raspberry. I decided to set it up as a server on the Internet and see how many years I could keep it running without a reboot. For me, setting up a server with uptimes running for years is no trick. I decided to spice it up and run it using 100% solar power that I generate at my house, with no connection to the grid (not even for backup).”(read more)

Devon shared: “This post is many months in the making and I am very proud of the thing’s I’ve done here, and very thankful to all of those (specifically at who have helped me along my way to getting this project up and running.” (read more)

ContractorWolf shared: “For my second real project for the Raspberry Pi I needed it to be something that took advantage of the recently released Raspberry Pi Camera Board. My idea was to make an extremely simple “point and shoot” camera. I wanted it to be able to run on batteries, connect over Wifi and have as much of the project inside of the original box as I could.” (read more)

Mike Cook shared: “A Lensman microscope is attached to a Raspberry Pi camera. This is what I found. The moving images from a drop of water show Frank & Herbert swimming about. The mites found in my box of bird seed are not so cute. All the other images are from mounted slides.” (read more)

Alex Eames shared: “the very much improved version 2 of the RasPiCamcorder. I originally built a quick and dirty free-standing camcorder two days after the Raspberry Pi camera was launched. I was in a hurry, as there was a Cambridge Jam two days later. Major novelty factor.” (read more)

Drew Fustini shared: “Linux Pro magazine’s steady hands Raspberry Pi game with Adafruit parts at Maker Faire KC” (read more)


SuperInfraMan shared his Box for Mini Arcade Joystick and limiting plates: both super handy! (read more)


Matthew Plummer-Fernandez shared a popular model from his Digital Natives collection to the 3D printing community at Thingiverse! “Popular 3D print from my Digital Natives collection that I’ve decided to give away to the 3D printing community to say thank you for all the support. The colours have been changed from the original. Feel free to print at different scales but tall works best, and explore colour.” (read more)


Artist Micah Ganske shared experiments with the plastic-specific one-coat Krylon Fusion spray paints and has been having good success coating a massive assembly of parts to make it look as if it was produced that way: “Krypton Fusion for Plastic adheres pretty well to PLA without sanding or priming! 3D printers go!” (read more)

sicksad shared: “I have been experimenting with using a computer controlled delta robot to draw long exposure light animations. By using a precisely controllable robot to draw each frame of the animation a level of precision is achieved which gives the animation a quality similar to that of CGI animations, while still maintaining natural lighting. The process of drawing a single frame can be seen in the following video. This would of course take place in a darkened room with a camera set to take a long exposure photograph pointing towards the base of the delta robot.” (read more)

Asier Arranz aka Lab-Man shared the first native game for Sony Smartwatch: “Two days ago I read that Sony had opened the SmartWatch to allow custom firmware, and what was my surprise when I read that my friend David Cuartielles (co-founder of Arduino) was behind the first hack to compile with Arduino suite! So I started to work to launch the first game “fairly” cool. It was still dark! I thought go to bed early, but it began to be addictive when I saw what I had in mind was becoming a reality in my wrist.” (read more)

Rosemary wants more Circuit Playground! Good news for her request: next episode is coming soon! (read more)


littleBits shared with us about the “pulse” bit: “The pulse Bit is like an electonic heartbeat. It sends out a stream of short ON signals, and you can make the speed of the pulses faster or slower using the included screwdriver. It’s great for making LEDs blink! We see and hear the effects of pulses everyday; for instance, that steady beat you hear playing in your favorite song or the steady blinking of a bike light is controlled by a pulse.” (read more)

Check out “Vi Hart takes on Stravinsky’s ‘The Owl and the Pussy Cat,’ in a musical animation.” A video our community deeply enjoyed. (read more)

Felix Rusu shared what Hack-a-day described as the definitive tutorial: “This is a walk-through for making cheap high quality SMD metal stencils at home, using commonly available materials.” (read more)


Community member djdc23 had some help on the Adafruit Forums sorting out the code for the construction of an Arduinio-based animatronic “Billy the Puppet” (from SAW) character! “It’s being made for a Halloween party I’m having in October.” (read more)

Jeremiah Warren shared: “I’ve always been fascinated by the time slice technique (also known as “bullet time”). Probably the most famous version of this comes from a scene in the first Matrix film where Neo dodges a series of bullets. To capture this look the filmmakers set up an array of cameras that fired off at high speeds in sequence. After a lot of work interpolating frames (creating frames between frames) using an in-house software program (now known as Twixtor), they were able to achieve the final effect.” (read more)

Eduardo shared: “This is my pong version. I built this using an Arduino, 2 x LED Matrix 8×8, max7219, a small speaker, and a potentiometer to control the bottom bar.” (read more)

Kevin in the Adafruit Forums shared: “Using the IOIO board and the Adafruit 16 channel PWM controller, I was able to control up to 16 servos over bluetooth from my laptop. The code will also work with some minor changes from and Android device. Take a look at the code and the video.” (read more)
