Cheers Steve for the warning. I'm an Electrical Tech, limited rego and very safety conscious. Had enough scares in my early days to keep me cautious.
I've been using a modified 400 watt PC Power Supply to drive my gear. Delivers about 10 Amps at 5 V, 5 Amps at 12V, very smooth and quite small for it's output. Simple resistor mod to trick the PS into thinking it's got a load connected and away she goes.
I'm a great believer in using already available resources.
What diversion ? It's all good
