Let's Make Robots!
Analog, Serial, Motor Control, Audio, Video, Xbee, Bluetooth, PWM... Everything!
Chris was nice enough to send me a little project of his called the 444AVXB. Why the weird name? Well, because it does EVERYTHING. 4: amps of motor driver power (2 … Read more
Okay this is just a concept at this point, but If it generates enough interest i'll begin finishing the design. I want to take the Sanguino, Arduinos Middle child … Read more
I've noticed alot of posts lately have been about faulty power supplies, mainly because they are utilizing a 9V battery in their circuit. 9V batteries are intended … Read more

MCP73213 Dual Cell LiPo Charger Recommendations

What are some things you would like in the upcoming dual cell LiPo Charger? Right now, the charger will feature:
1 amp and 500 milliamp selectable charge rate
Charge Indicator
Charge control
USB input or Wago screw terminal/JST connector/ Header?

Anything else?

MintyProbe, the Altoid can logic probe

Inspired by Andersen and CTC, I am putting together a Logic Probe Kit consisting of:
     MintyProbe, a tiny 3.5"x2.25"x.75" Logic probe with 2x16 LCD Screen able to:
                Detect High, Low, Floating Inputs
                Signal Pulse Length
                Voltage readout (5V and Under)

MotorCityRobots.com

Myself and a local member of a hackerspace in Detroit recently started a new website devoted to robotics in Detroit. Right now the site is brand new, with really no content. So what I'm asking you to do is to sign up on the site, create a couple posts, etc just to generate some content. I'm not asking you to leave LMR, just check the site out (whats there anyways) and if you're proficient at drupal send me a PM, so you can help out the site too! Thanks.

Zekk, you make me cringe. Here's your graphic.

Here. Connect the 9V output to the Propeller/5V regulator, and the 6V output to power the servos. Use the ground on the 4aa pack for both supplies, both the servo supply and the 5V regulator.

Free Motor Controllers!

I am currently designing some very budget friendly Motor drivers, and to test the design out, I am giving away 10 free drivers! Each driver is a single or possibly dual (5 single and 5 dual) transistor based design, and cost per board is very, very low. If you would like one of these free driver boards, please post in the forum below. No restrictions! Each board ships with a application note so you know how to use it.

A few specs:

Max Voltage: 30V

Max Amperage: 0.6A
