Car alarm remote control repurposing

A while ago, I got hold of a car alarm unit and its two remote control fobs. When i hooked it up to 12V I realized that it didn’t  work, not responding to any of the commands from the two fobs even though their batteries were OK. Naturally, I opened up the unit to start harvesting parts and noticed the RF module within (the one that sticks out perpendicularly) and I figured it shouldn’t be too hard to use the module with an Arduino.

Robot A.I. idea for non neural network approach.

In this Blog I am simply gethering my thoughs in preperation for a long term project. Hopefully some programming Guru's will post some good ideas. Maybe it will inspire someone else. I am just one nueron in the huge brain of humanity.

Personal History
When I was 12, I taught myself to program in GW basic on an IBM clone that ran at 8MHz with monochrome, text only graphics and a 5¼inch floppy disk drive. At that time I wanted to write an artificial inteligence.

3.3 Volts to 5 Volts the easy way.

It doesn't get more simple than this...

The above circuit worked to let a 5 Volt servo work on a 3.3 Volt signal. This DOES NOT convert power so connect the servo power connections to 5 Volts and ground. This only converts the low power signals (before this my servo wouldn't move!)

Now, the resistor is 1000 ohms or 1 K (brown, black, red). Wattage isn't citical. The diodes are 1N914 or 1N4148 any good silicon (Switching) diode should work.

Helping a special friend with his first robot,

I am helping with my friends first robot! He primaily wanted tractor treads and an Arduino "because he heard they were good" ( I didn't disagree with him. :-)

We decided on an inexpensive kit was a good starting point and then it can be expanded later.

Our choice was the BrutusBot and electronics package (looks like I get to solder 2 boards, lucky me...). It was fairly cheap.

He seems good in the programming and mechanical areas, he isn't so good with the electronics part (he does fine with some guidance).

My 'little' robot bee lacks the power of flight but makes up for that with its 350 volt stinger! I built this little bug bot one day out of a few switches, two … Read more

Super Basic

Hey guys, I am a Product Design Engineering student at Glasgow University / Glasgow School of Art, and we just got our project brief for this semester. In groups we have to make a multi-purpose vehicle that competes in a series of challenges, in a sort of 'Vehicle Olympics'. So, the challenges are:

1) Hill climb - 20m track up a steep hill. Simple time trial.

2) Tug of War - Vehicles will be tied back to back, on a Vaseline-covered area. First robot to get further, or out the ring wins

Add-ons to the "bristlebot"

Have any of you added something cool to your bristlebots to make them do something cool (like obstacle avoidance, remote control, etc.)?
