Got myself a new little gizmo for R2 today. It’s a small 75Mhz RC frequency scanner that I’ve dubbed “droid caller”. It allows me to make sure the frequency I’m using isn’t already taken. It was only $10, and I think it’s worth the investment.

I’ve taken Artoo to a couple of events now where there’s been a bunch of different bots running around. Most have been well organized with a check-out system for frequencies, but at one I did get a few glitches which I suspect was a conflict with another RC unit.

I’m hoping this device may save me some time troubleshooting problems in the field.
