Simple electronics videos

Hope these videos might be of help to somebody beginning electronics, schematics(electronic diagrams) will be coming soon for each video.

For the Turnigy TG9e servo used within the video below I used the following code to test it, using pulses with a picaxe 8M.

 

symbol i=b0

pause 100

main:

 

for i=0 to 100

pulsout 2,75

Walter: Virtual Control Panel

Just a quick update on what I've been working on. I am building a virtual control panel with Processing and the controlP5 libraries. The video is pretty self-explainatory, and understand what you are seeing is a work in progress as is the code attached. If you go through the code, you will quickly see a lot of stand-in values and lables that still need to be gone through, but never the less, the "system" is rock-solid. I think that's it...

Android phone as a controller

Hello there :)

I'm on the edge of purchasing an android phone. Looking at specifications around i thought: "Hey but this is the perfect controller for a robot!!" It has an incredible inventory of useful stuff: gps, compass for navigation, wifi, bluetooth and cellular for communication, huge screens for UI, speaker for talking, plenty of cpu, camera, easily programmable, and so on, all packed in a small package, all low power! And all for as less as $200! What do you want more ??

There's only a drawback: there's no simple way to phisically connect a device to peripherals :(

B5 progress

Whatup gays,

Calculon just wanted to drop a line and share his progess on his B5 (the Backyard Beverage Buddy BBot) project. He started his project last fall as his entry into the XMOS challenge. The idea is basically a cooler on wheels that rolls around Caluclon's backyard and offers beverages to people. That's still the general plan, but the scope has changed slightly.

B5 1.0 features the following:
