=== Photo Sensitive Board ===
It is possible to sensitise your own board by getting a coper clad board, cleaning and coating it with photo-resist and allowing it to cure.  However it's vastly easier just to buy some.
See [[Pcb_etching_instructions#Results_people_found_with_materials.2Fcompounds]] for a list of known good materials.
You may want to try:
* [http://www.rapidonline.com/tools-equipment/photoetch-pcb-29445 Photoetch PCB (Rapid)]
* [http://www.megauk.com/pcb_laminates.php FPC 16] (various options there, FPC 16 seems to be the cheapest)
'''NOTE''' : the developer is from Mega Electronics, also sold through Rapid. It works well with photo PCB material from the same source. It does ''NOT'' work with Maplin photo material !
