One thing I've have to have to make this project stand out is a good lunar surface. My current plan is to wet the landing surface with water, sprinkle on some grout, let it set for 30 minutes, remove any excess, then repeat until it looks reasonable. I think this may work....
A slight mod to the suface testing. Now spray the surface with adhesive, sprinkle on some grout, spray again, repeat. Also trying to insert a few random rocks into the mix. I think this is better and getting very close to the effect I'm looking for.
The PCB arrived from JCLPCB. Arduino Nano and sound card from Adafruit also now here. It's a simple circuit -- just a couple of motor controllers and some voltage convertors which could have been easily done with a perf-board, but I think having a real PCB makes everything look more professional.
After some thought, I've decided to print the base and tower. I figure I can always go back to the orginal plan of constructing it out of wood if it doesn't work out. It will just take some time. PLA with a fill density of 5% seems to be strong enough. With a little filler and sanding it should look good. Nothing is glued yet.
