Need an opensource electronics project, check codemade.io first

Posted on April 18, 2017 by robertwilkie

Its like a cross between instructables and thingiverse for electronics. Mostly mod’s to things like arduinos and RPis for electronics. http://lifehacker.com/codemade-is-a-big-collection-of-open-source-electronics-1789750030 sample https://www.codemade.io/search/camera

Adjustable Wire Foam Cutter with an Arduino

Posted on April 18, 2017 by robertwilkie

Interesting build, but couldn’t the author done the same thing with the POT being inline instead of using an arduino? I wonder if the author has other plans for this. https://www.instructables.com/id/Hot-Wire-Foam-Cutter-Arduino-PWM/

Build an arduino with a panel display built in

Posted on April 14, 2017 by robertwilkie

Nice build. Basically its a homemade arduino with a display on the other end. That way you can pop it onto a case and look pretty professional.

Cool clock with an arduino and a Neopixel strip

Posted on April 3, 2017 by robertwilkie

Pretty nice build, Only downside is if you buy NeoPixels from say Adafruit, its going to run you around $20 just for the LEDS (not including power supply, arduino…etc). https://www.instructables.com/id/Arduino-Colorful-Clock-Using-Neopixel-Strip/

Neat small robot arm (littelarm 2c)

Posted on March 30, 2017 by robertwilkie

This arm is small enough that it should be printable on most hobby 3D printers. Could be a cool project to do with kids. http://www.instructables.com/id/3D-Printed-Arduino-Robot-Arm-LittleArm-2C/?ALLSTEPS
