Using a Stirling Engine to power an arduino

I was just looking at one of these engines too on ebay.  I was thinking more for using sunlight, but this is still pretty neat. Ethanol-Powered Arduinos

Use a sawzall to shake cans of paint

Interesting build.  The author basically took a sawzall that wasn’t working out for him and made a paint shaker out of it with an arduino to control it.  The write up is pretty good.  And if you have a broken … Continue reading

Need an opensource electronics project, check first

Its like a cross between instructables and thingiverse for electronics.  Mostly mod’s to things like arduinos and RPis for electronics. sample

Adjustable Wire Foam Cutter with an Arduino

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.

Cool clock with an arduino and a Neopixel strip

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).

Neat small robot arm (littelarm 2c)

This arm is small enough that it should be printable on most hobby 3D printers.  Could be a cool project to do with kids.

Simple Stepper Driver

Basically this is a nice write-up on a simple stepper driver with an arduino nano and a EasyDriver board.  Easydrivers are a nice stepper motor controller, but….they are a bit pricy
