Arduino and Other Electronics Projects

Miscellaneous electronics and microcontroller projects:

Make and RadioShack's Drawdio:

Initial test of this 20x4 character screen.  Notice the Haiku

Small Screen Blues

Screens 20 by 4

Focus encoded messag

As haiku does

 First fully custom project.  Writing a 'guessing' game that uses a RadioShack RGB LED Strip, the screen, LEDs, and 6 buttons.  Already maxed out the memory of the little chip on the Uno R3.

 Moving my dev environment to Raspberry Pi.  The borrowed laptop I was using is going to be repurposed and will live in an inaccessible place.  Here is the Pi running the Arduino IDE.

 Used Google, and knowledge from a class at SYN Shop, the local Hackerspace, to remove and troubleshoot this module.  It is a Blower Motor Speed Controller from my car's AC.  I found out the transistor in it is bad, but replacing it would take more effort than it is worth.
