RC car telemetry

telemetry

Meghan Desai and Yiling Li built this radio controlled car telemetry system for their “Designing with microcontrollers” class. They had looked at several other RC projects and decided it would save a lot of trouble if they didn’t attempt to work with the car’s on-board microcontroller. They built separate boards to house the four IR sensing pairs, temperature sensors, accelerometer, and an Atmel Mega32. All of the collected data is transmitted at 433MHz. On the receiving end is another Mega32 that processes the data and formats it for display on a TV. They’ve done an excellent job documenting their project.

If you have to do a design project this semester, we’d love to see it. Just get some free hosting from Blogger and post your project. I’m using Blogger as an example since they don’t crash and burn when we link to them.

    I’ve got an old tamiya tt-01 sitting around that could be chopped up for a more high end version. The accelerometer could be used by itself just for analysing the cars performance.

    Personally, I found the completely DIY video out on the reciever to be the more interesting end of this one.

    Some TV hacking info I dug up:

    Very interesting, what kind of information does it report back?
