Re: [Ann] US based Avalon ASIC chips and assembly: 3,733 remaining

That wall wart you linked to puts out 12 V, which is fine for a K16(iirc), but the RPi needs 5 V. An LM7805 or similar would do the job.

7805 is from the 70s, you would be better off with 2 wall warts than wasting 7V @ 500ma of heat from a 7805. Consider a simple USB cigarette lighter converter from ebay. or http://www.ebay.com/itm/DC-Converter-Buck-Step-down-Module-12V-convert-to-5V-3A-USB-Car-power-adapter-/171061990530
