Its always fun learning something new. Ever since we got a 2.4 GHz RC system a few years ago, I wanted to understand how these things actually work. How do they send data over the air? What components are used?
Well, in the last months we finally got around digging into it. And it turned out that it is a rather simple affair. So we built our own RC receivers.
The HobbyKing HKR3000 and XR3100 receivers along with two different versions of compatible, home-brew receivers.
It has been a while since be blogged about our Light controller. In the meantime we have equipped more than ten cars with our custom electronics.
In this post we describe the changes we did along the way to the electronics and the firmware.
Can you spot the problem with the throttle trigger in the following picture?
If you look carefully, you can see that the throttle trigger on the right transmitter is slightly depressed towards the grip. This is due to a fault in the mechanism that returns the throttle trigger to the centre when you release it.
Fortunately it is not difficult to fix this issue.
