Hi all,
After reading loads of forums and pages online, I have a better idea of my project, but still needing a bit of help !
I'd appreciate if you could "check" my set up and give me any advice, so here we go :
I am trying to build a DIY video projector, from a LED, a LCD, a fan and a couple lenses.
My LED is 30v,1A, my LCD is 12v,<3A and the fan is 12v,0.3A and I would like to power all this from a single power socket rather than having two different plugs.
SO I thought about having 2 transformers connected to the mains, a 30v 1.07A one for the LED, and a 12v 5A one for the fan+LCD. Both circuit would be in parallel and the fan/LCD in parallel. Each "sub-circuit" would have a switch so the fan could be left on after the light has been switched off.
The 30v and 12v transformers are here http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350390453297 and here http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=280521186928
Would this work ? Can the 2 transformers be connected in parallel safely ? Does the LED need a proper LED driver or could a resistor in series be enough to have constant current/voltage ?
Any advice would be very welcome !
Thanks,
Ronan
