Cisco Purses Cubed!
summary
Twelve discounted pixel purses become a single working LED cube by reclaiming 12 purses for their hub75 panels and 48 AA cells and by repurposing obsolescent Cisco FPGA boards bought on eBay. Design uses KiCad/JLCPCB PCBs, an FPGA driver and a soft RISC‑V core to feed the panels, and mechanical legs nailed to precise hole locations. Assembly involves about 60 screws and UV glue to prevent shorts, and the cube boots and displays graphics in the demo.
