Just scored a deal on a Noblex panoramic camera, but the catch is that it's a fixer-upper with multiple electronic problems.
Top cover comes off easily enough. Top and bottom covers and camera back are plastic, but the chassis is a very stout metal casting.
Circuitry consists of off-the-shelf components and looks to be a MOSFET motor controller with 555 timer chip. I don't have the know-how or schematic to troubleshoot it more systematically, but I can simply replace all of the semiconductors if need be. I've got it semi-working now with the lens spinning as it should, but the speed is always the same, so there's more work to be done.
