Try Monox, an English company repped out of Canada ( at least in NA). It is reasonably priced, compared to Cititek (also out of England). You will find that most english cells are Electrolytic, and have faster updates. And most Japanese (like Figaro) are Sintered Tin Oxide, which has it's own positive aspects but also has a slower update. The demo kit from the Canadian for Monox is junk (it oscillates, a key flaw). I have a preamp board that goes on the back of the cell for a project that didn't go anywhere. If you want the Schematic, PCB, and BOM, I am sure we can make a deal, maybe in trade for something. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
