I have an old computer power supply that has been removed from its computer so I can use it to power up my Grinch boards. I have been told that when you plug the power supply into a 240v outlet I need to bridge a couple of wires coming out of the 5v side to trick the power supply into thinking a computer is connectrd to it so the 5v leads can be used. Can someone tell me how to do that?
I hope that make sense.

Cheers, Terry

the simple way to do it is to use one of these adapters

i have a couple of boards left out of the first home etch run, but we are going to coop a production version of this based on interest.

this link gives you the pinouts if you wish to do it yourself

Thanks Phil

My electrical skills are very limited so I will show this info to my son who is an electrician and I am sure he will be able to sort it out for me.
Can you supply me with more info on your boards please (price, picture etc) If my son thinks I should go that way it is good to know I can get it from you.

Cheers, Terry

sorry you couldn't get to see the picture, here's one I made earlier :)

That is the Home Etch Board.
The BOM can be found here
http://xlcbom.incanberra.biz/pdetail.php?id=5&name=ATXPAv2

pricing to get it professionally made.

Assuming 50 boards the cost will be $6.50 US per board, if we get 100 the price drops to $3.75 per board.
Double Sided with component overlay and solder mask.

Plus shipping to you.

We currently have interest at 38 boards so we are close to getting it cooped.
