If anyone has any alternatives then please say before I go and buy one of these
Looks good to me. Are you going to use this just for external +5vdc devices, or are you also wishing to power your Arduino board at the same time? Wiring +5vdc directly to an Arduino's 5vdc pin can be tricky when you then plug in the USB link as you are then tying in two different +5vdc sources together and that can lead to problems as they are usually not at exactly the same voltage.LeftyLefty
Have you gained a second name somewhere?
Must have been typing from both sides of my brain.
Just a word of caution. The problem with a supply that can provide a lot of current is that it is very unforgiving of short circuits. Things tend to melt rather than just trip the over current protection. This includes tracks on PCBs vaporising. This is much more difficult to repair.
And here's a little reminder - this offer still stands since I have a big pile of various models in my garage right now: I'll send you one free plus the cost of shipping.http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1254460064
If you short one of these babies out, you'll make heater elements out of your wires, if for only a moment. So be sure to put a light-weight fuse on there or at least be very careful. I accidentally shorted mine out on the 12V line and effectively arc-welded a paper clip to the pin of a 50W halogen bulb. It was rather startling.
Can you stick up a few photos?
You got any small ones? Fanless ones? Ones that don't weigh a tonne?
