RF Remote Prop-1 interface

Today, I finished creating the Prop-1 to RC controller interface circuit. The schematic, for ExpressSCH is available here.

It works like a charm, all simple transistor logic, no relays, no nothing. Now, with a simple 3 lines of code in the Prop-1 program I can remotely trigger a prop ~30 feet away.

One cool thing of note, I submitted the schematic to the support forum for the Prop-1. The head programmer / developer gave it his ok, and complimented me on part of the design.


More on the remote front

Well, I couldn’t stop at just the crow, and the flying ghoul. I found in my bins of stuff a screaming head I got from Target a few years ago. I never did set it out anywhere, but I took a look at it, and found it was indeed quite hackable. I dropped in the receiver board from another of the remote control cars. This time though, I had already used the Forward,and Reverse signals for other props, so had to do a little hacking to the receiver. Fortunately the chip in the car is capable of five separate actions, and the chipset is documented on the net, so I used one of the unused channels and linked it into the head. I then had to build a remote that had buttons for all five signals. I built that, finished the interfacing of the receiver and now have the ability to trigger the head from a remote. Tomorrow morning I’ll build a second transmitter for the Prop-1 to use to transmit.
