I'm looking for a power supply to run my latest gadget (laser display with green laser and 3 rotating slanted mirrors). At the moment it uses a rechargeable battery pack "borrowed" from an old R/C car but this doesn't last very long at all. It's ok for showing it off but for longer use (ie. at parties) it needs to be wall powered. I've done some testing and these are its stats:
Input Voltage: 5v
Max. Startup Current Draw: 4.7A
Normal Startup Current Draw: 0.3A
Max. Running Current Draw: 3.6A
Normal Running Current Draw: 2.5A
I know I could buy a big transformer and build a rectifier/smoothing/regulator circuit. What I'm trying to find is a company or individual that supplies the pre-built "wall-warts". I could probably find one with the right voltage around the house somewhere but the problem is the high current draw from them.
Any advice?
Thanks.
PS. Transformers - what's this "VA" rating I'm seeing all over the place?
