A hardware mod not for the faint of heart, but one that gives the C.H.I.P. some legendary button control – documented at the NextThing Co. blog & bbs, with full repository of notes available here at GitHub.
The purpose of this project is to create a mainboard that acts as an adapter between C.H.I.P. and the PSP. It shall have the same form factor as the original PSP mainboard and connect easy to the existing flex connectors, e.g. the buttons and the display. It shall also carry the DC/DC converter circuit to power the display backlight and accomplish the conversion of the display signals. It shall also provide the required software and firmware files for chip to use the PSP hardware.
