Make your own skittle sorter

OK I know this has been done before with arduinos.  But this time all the “parts” you can print out instead of having to cobble them together from god knows where.  Its a cool build and has alot of thought … Continue reading

Print out your own camera slide

Pretty nice camera slide that is all printed out except for the screws and bars.  I like the adjustable feet for it. http://www.3ders.org/articles/20150908-make-a-3d-printed-camera-slider.html

Nice write-up on upgrading a Chinese 3020 CNC

Good write-up on how to upgrade an $800 CNC from China to be more modern and robust.  My 2 cents, I think I would spend the money on a shapeoko instead. http://www.instructables.com/id/3020-CNC-Arduino-GRBL-CNC-Shield-V3/

Redneck windmill project

This is one interesting windmill build.  Has the standard PVC blades and cover for the motor you see in other builds, but I found it interesting the an old saw blade was used for a hub.  I guess it works … Continue reading

A $15 RPi

Finally, a Raspberry Pi cheaper than an arduino.  This is the Orange Pi, which includes a few extras over a standard Pi (IR reciever for example).  But for $15 (30 if you want one with build in SSD and WiFi).  … Continue reading

Upgrading an old alarm system with an arduino

It looks like the author reverse engineered a few bits on an older alarm system to give it some more modern features. http://hackaday.com/2015/09/05/upgrading-your-alarm-system-with-an-arduino/

Building an underwater robot

The frame for the robot is pretty basic PVC stuff.  The interesting part is how the author waterproofs the motors (from standard DC motors to waterproof ones). http://www.instructables.com/id/Build-an-Underwater-robot/

Another CD-ROM to Mini CNC build

This is a nice build and cheaper than some of the other ones I have seen.  The author uses a smaller Arduino, and L293D chips to keep costs down.  Of course he ups the costs with other stuff. http://www.instructables.com/id/Mini-CNC-Plotter-Arduino-Based/
