100 Miguel Castillo Google Tutorial on How to control your water consumption with an

Miguel Castillo shared: “Tutorial: on How to control your water consumption with an Arduino a RaspberryPI and a flowmeter. This easy tutorial (step by step to DIY) helps you to control the water used in your garden watering. To do this, we use Arduino and Raspberry Pi to get the best of both. All the source code is included.” (read more)

Jaidyn Edwards shared: “The first part in a multi part video series where I show you how to make your own robot!” (read more)

Miguel Castillo shared: “How to make an internet Stuffed Toy with Raspberry Pi and Carriots: A few months back we had a developer contest @Carriots to build an IOT Stuffed toy. As an example we build a Domokun that was able to:

  • Tweet
  • Talk (with Text To Speech)
  • Download video from Dropbox and play it on a video screen (placed at the mouth of the Domokun)

Here is the tutorial to DIY (with all steps, source code and schemas). You can use this example to build a toy of the future for a kid of your family! The video was done by our team of engineers to promote the challenge. You can build all the components in Adafruit for less than 150$ Enjoy it!” (read more)

Alexis Wiasmitinow shared an EveryCook update: “We finally made it! After many hardware troubles and software bugs it works! see: EveryCook digital cooking success…” (read more)

Paolo Galeone shared: “This is the alpha version of a 16 bit synthesizer that some day will be completed. It works with a PIC32 (on board PIC 32 Pinguino OTG, designed without pinguino language [the same of Arduino] but in C with the MIPS toolchain patched by pinguino team [] to work with gcc interrupt attribute). It use the ADC module, and the timer1 that works with the secondary oscillator.” (read more)

100 Sven Haiges Google The 555 timer ic finally works Second try and i am a bit

Sven Haiges shared: “The 555 timer ic finally works. Second try, and i am a bit frustrated as all these cables and resistors are quite easybto get wrong. Little bang for the tons of cables. Doing this to get a more fundamental understanding of electronics. Is that worth it or should i just concentrate on Arduinos, Beaglebones, etc and do all logic in code?” (read more)

Michael Overstreet shared: “DARwIn-OP climbing a Ladder!!! The programming of the robot was done by the Autonomous Agents Lab, University of Manitoba.” (read more)

Thomas Edwards shared: “I’ve got some inverse kinematics going on the robot arm – you can see me drive it in kind of a circle. More calibration is required though!” (read more)

Ryan Williams shared: “So I posted my first Instructable; it’s a different method of DIY PCB etching. Take a look and let me know what you think!” (read more)


Martin Atkins shared: “Continuing my little notifier/clock project I posted about last week, today I made a cardboard prototype of the enclosure to check the dimensions. Eventually I plan to get this cut out of acrylic but I don’t have access to a laser cutter myself so I use the cutting service from +Pololu Robotics and Electronics . I’ve been bitten before by not prototyping my design before submitting it; in one project (the “Radiant Mural” I posted a video of some months ago) I accidentally lost a millimeter on a repeated part while making my design file and it added up to 24mm lost over the full width of the product, which required some hackery to work around once I got the parts…. My previous post showing my breadboard prototype is here.” (read more)


Ian Henehan shared: “All the staves have been scarfed together. Today I got to glue up the ‘ladder’ with the sides and blocking for the mast.” (read more)

Jari Komppa shared: “SoLoud, my free (zlib/libpng licensed) audio/sound effect playing library now includes a speech synth. That’s the biggest news, but I’ve also torn through my TODO list quite a bit. Still a lot to do, though.” (read more)

Gert Galjoen

Gert Galjoen shared: “Extruder Optical Filament Control Retract Load Feed , Exercise. Setup for this try out: arduino nano 3 + finger mouse + SPI display “open jumper 12864″. The sensor has 1200 DPI (theoreticaly). For a distance of 10.00 mm I get a value somewhere around 220 steps….” (read more)
