The latest version of Space Rock #4, sanded and with the circuit board and powerbank holder printed for inside. Also shown is a version of Space Rock #1 printed in sections at 280mm wide, and coated with XTC 3D as a test as this print has lots of flaws – not least because the filament snapped just before finishing printing the front section, so I had to do a patch repair. Interesting to see how smooth this sands down.
Two revised Space Rock circuit sketches. One (above) showing positions of magnets to be used as a closing mechanism. The other without a sensor, as I hope to use the RSSI data from X Bee to influence the sounds from the Space Rocks, meaning no additional sensor required.
Managed to get the XBees talking to each other, following these steps. The video shows two completely unconnnected Arduino circuits. The one on the right (coordinator) sends the reading from the potentiometer to fade the light on the board on the left (receiver).
