A remote controller is something I’ve been wanting/meaning to build for quite some time now. Like years. I just never really had anything that required one. Now the Wall-E project is at the point where a remote would come in rather handy. So I guess it’s time I get something done.
The original, back-in-the-day idea was to use infrared, but they’ve since made this 2.4GHz thing easily available and I now have a handful of el cheapo knockoff NRF24L01+ modules. So Wall-E gets one, and the remote will get another (leaving me two more to play with). I’m going to use my knockoff Arduino Mega to run the thing. I’ll throw the SeeedStudio touchscreen and protoshield on it, and probably a couple of pots and switches and buttons. I’ve been hanging on to old r/c parts for ever, including the remote for my old Sabre helicopter which is busted and hanging from the garage ceiling, so it will at least donate it’s joystick(?) and battery pack parts. I think I may try to hack up the top portion of the remote to hold the Arduino and screen bits. If that fails I guess I’ll have to make a custom housing out of something. That 1/8″ fiber board worked pretty well for the power supply (also visible in this picture, as well as the old calculator that prompted the PS build) so I may go that route if necessary.
Well, this is a pic of the second one. The first one worked okay with minor drill work so I figured to just do the second one the same way. These are just axle embiggeners for the Wall-E project.
The bottom one is what connected the single motor to the treads, the top one is the 3D printed one that’ll allow two separate motors to drive the robot. The flattened-circle hole that was supposed to slip over the motor shaft was a bit too small, but grabbing it with pliers and drilling opened it up enough to jam it in place.
I have printed out a few things from Thingiverse already. There are a few helper bits on the Printrbot, and I finally got a case for my Bus Pirate, as well as a snazzy NES looking case for kiddo’s Raspberry Pi. This is the first time I ventured into making my own though. It is so friggin awesome to be able to draw a part and have it in my hands twenty minutes later. Now I need to work on my grasp of CAD software…
