I’m planning the next version of my Arduino-RC transmitter interface cable. I’d like to add some shielding on the cable, and a ferrite too… I suspect the current cable is rather ‘noisy’, but I valued spiral cable over shielding. I hate tripping over trainer cable, especially while wearing video goggles and plotting the take over of the planet.

I’d also like to power the arduino from the transmitter battery, which should be relatively easy… The diecimila board uses a Low Drop Out regulator and will accept anything between 6 and 12 volts, while the Royal Evo transmitter’s battery is a 6-cell series battery, good for something between 7 and 8 volts.

According to this site‘s pinout and to my multimeter, there’s battery power available at the plug both in always-on and on-with-radio versions. Since the arduino boots faster than the radio, I think using the switched version would be best.

I bought two plugs the other day, so all I really need to make the second cable is good spiral shielded cable and some ferrites.
