My mate kindly donated his old broken TomTom Go 300 from which I was hoping to steal the GPS chip and antenna for use in my Arduino projects. I opened it up and found the GPS unit, it was labeled Cirocomm G100/300 580...

After my semi successful prototype of my remote control car speedometer project using a reed switch, I'm back with version 2, this time using a hall effect sensor.

I love my Arduino development board and have done some interesting experiments with it, and now I am at the stage of wanting to make some of my circuits a bit more independent and permanent...

I've recently acquired a laser pen, and of course, instantly dismantled it! I bypassed the push button and soldered on a couple of wines replacing the batteries, allowing it to be powered and controlled by the Arduino.

As mentioned in an earlier post, I suggested the motor driver IC would be preferable over four transistors and lots of wire due to it's small and neat package! However I have just realised something that may sway me in the other direction...

My motor driver IC (L293D) arrived the other day, and before I put it to real use I thought I would just have a quick go at driving two motors at once...

My mates mouse stopped working the other day, so I thought I would have a go at fixing it, assuming it was probably a damaged cable as is usually the case. After checking the continuity of the cable we decided this wasn't the problem. So I had the mouse apart and started poking around looking for bad connections or damaged components, and discovered something pretty weird.

The next thing I wanted to try doing with my Aruino was driving some motors. I have got loads of old CD/DVD drives that I don't use any more and thought this would be an ideal source of motors.

For my next project, and this is one I have been wanting to do for while, I will be makeing a speedometer for my remote control car.

So, I have not long had my Arduino development board, my first project was to try and get it to log data to an SD card. This will be essential for a few future projects I have in mind. The internal EEPROM is only 512bytes, so not particularly useful for logging large amounts of data.

In anticipation of my Arduino development board arriving, I decided I will definitely need a decent power supply. I have loads of old adapters laying around from phones, routers and other old devices, but these are usually quite low voltage and current. I wanted something with a bit more juice, something with some nice high voltages that could really pack a load!
