Back after a long time, motor moving

Well, I disappared for a long time there.  I moved to Austin and started a new job :)  Oh, and I had to learn to solder to get the motor drive set up with the breadboard pins.  My girl got me a gret Edsyn soldering setup and a solarbot light following mouse to practice on and now I'm all solderiffic :)

butler bot

 i have this idea for a butler bot. inspired by Norrislabs (BDS) beverage delivery system http://norrislabs.com/.  it will have 1 propeller board it will handle motion, the sensors and a slave for bat lvl temp snsor and controlling the peltier units. it wil have 2 window up/down motors with a h-bridge for each. it will be powered by 2 12v bats for the motion and a 7.2 bat for the prop boards and speakers. the whole thing should be about 4 ft tall.the fridge should hold 3 sodas depending on the size.

The Robot Builder's R-duino

June 24th, 2011.

I've been asked if I can make a board similar with the Robot Builder's Shield that also has the microcontroller on board and is compatible with regular Arduino shields. Not an easy task to do if I want to keep it with through hole components, but it's a challenge.

So I have designed a first prototype of the Robot Builder's Arduino R-duino. Features:

Home made ROV for shallow waters
Update 11/9-2011 So I finally got a chance to take the ROV out for a test. I knew that there was a buoyancy issue as it floats to high in the water. So I took along … Read more

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
