Thanks for the reply captainshagnasty, but I'm trying to make it compatible with all PS2s. Since the voltage is regulated to 3.3v before going out through the controller port, this is the only way I can see of doing it. Thanks for the suggestion though. dz

I'm working on a small amatuer electronics project that involves connecting an optical joystick to a hacked playstation controller. A playstation controller uses a 3.3v source for it's circuit, which is provided from the controller port. The optical joystick I'm using needs 5v. I've thought about using a battery to step-up the voltage to 5v, but then I discovered charge-pump ICs that seem to do the same. Will this work? From what I've read -- again, I'm very new to electronics -- these switching charge-pumps are able to increase the voltage using a few capacitors at the cost of lowering the amperage. I'm not certain yet, but I believe the loss in amperage won't be a problem in this case. Here is the MAX682 IC I've been reading on that I think would do the trick: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1837 The problem is, it requires surface mounting on a PCB -- something I really don't have the knowledge/skills to accomplish yet. Is there any product out there that already provides a charge-pump IC and the necessary capacitors pre-mounted on a PCB? Dimension Engineering makes the AnyVolt Mini, but it's $28, and more designed for prototyping -- variable output, etc. I'm looking for something fixed. Thanks in advance to anyone that can help. dz
