What is the voltage on a AA battery? It would be around 1:30PM if you were using this voltmeter! A PICAXE 18M2 microcontroller is used to read an analog value, calculate what time it represents and then uses a stepper motor to spin the adjustment knob to have the clock show the voltage using the hour and minute hands. 🙂 Read more about the Analog Clock Voltmeter “The max
Thanks to David Powell from the Baltimore Hackerspace for sending in some details about the Lasershark which is a Laser Projector Project. It uses a LPC1343 – 32-bit ARM Cortex-M3 microcontroller to run the show, make sure you watch the video below to see this thing in action! “This board is intended to be a low cost open-source USB Showcard for folks who want to make their own 1

 A ATTiny24 is running the show here. This POV Wheel Display for a Longboard from ch00ftech looks like it took quite a bit of time to put together. Those tiny surface mount parts on the home made board must have taken a steady have to get right! There are more LEDs than microsontroller outputs but instead of using a serial to parallel chip to do the work the
If you have been listening to the latest episodes of The Amp Hour you have probably heard of Club Jameco.

If you decide to give it a try it looks like you will need to set aside a large amount
We have seen RoboBrrd before but very soon you may be able to purchase your very own RoboBrrd kit! Check out this Indiegogo. If you can please support RobotGrrl (Erin Kennedy) in her quest to have this kit become reality since I can see this platform helping all sorts of youngsters get excited about electronics and mechanics. You can pledge as little as $1 and you will still get the warm
