2 PCBs glued together, iCE40 devboard from Olimex and an old FireWire (IEEE1394) PCIe card with on-board PCIe->PCI bridge, wired together with a ton of little enameled copper wires on the left side there's a Raspberry Pi Zero W, wired to the SPI flash ROM for FPGA programming

@mntmn @whitequark and maybe don't do what I did and do this on a PCB instead :)
The ASM1083 chips are available and you don't have to sacrifice an old firewire card (like I did here).
IIRC this is also feeding 5V I/O into the 3.3V I/Os on the ICE40, but it didn't really seem to mind that.
