Full Version: Electric DIY
Friggin awesome. What do you reckon it cost you total?
$130.00
What about manufacturing kits (in small quantities of course)? I would imagine a few people here would like to have these available to them to hide the "big screen" when not in use.
hey barry,
i'm making an electrical screen too using a windshield wiper motor, but i'm having trouble finding the right transformer to convert my 120 VAC to 12 VDC. if you could let me know where you got yours from and what the output current from it is that would great.
Thanks.

Hi schultz1602
First I used an old, tired 2 amp power supply. I think this things original purpose was to supply 12v to bench test CB radios and automobile stereos.
In the first test I did not have the cloth on the pipe yet. I had the motor securely mounted in a vice. The other end of the pipe's mount was just hanging from a cord. The one end sort of loose allowed the pipe to swing freely, no binding at all. The no binding thing allowed a 2 amp power supply to work great! Once I got it all mounted in the ceiling as straight as I could get it and with all the cloth on I discovered that 2 amps is not enough... It would go around about 4 times and the power supply would cut out due to overload. It would cool and then turn another 4 times or so.
I was not real happy!
This little set back actually worked out better in the end.
I use a UPS to power my satellite receiver, receiver, HTPC, VHS and PACE STB. This is more as a protection from brown-outs not so I can listen to music if the power fails. So what I did was splice into the 12 +/- of ONE of the batteries in the UPS (if you use the positive from one battery and the negative from the other you will get 24 volts which is way too much). The single battey supplies more than enough energy to power the screen and because it is in the UPS it always has a full charge with no extra charger required! Since my UPS is always on I do not need a separate switch for 120 volts and one for 12volts. I just have the 12 volt up/down switch. Using the UPS will make it easier to eventually control the screen using my remote from the couch!
