What do I have here?????

Not sure that the videos came through.

Pretty sure those are stepdown AC to DC converters. There is a bridge rectifier, a good sized capacitor (to smooth the ripple), and an adjustable 317 regulator with a heat sink. The blue rectangular item will be an adjustable pot to set the regulated DC voltage.

You could certainly use that to power miller signs from an AC source. I would test it out by applying any AC voltage up to about 24 volts or so, and measure the DC output and set the pot to give you about 4.5 to 5 VDC. Have fun!

Thanks Rod. Memory is really not a strong suit, nor electronics. Just glad their are knowledgeable folk that I can turn to. I will test it out. Thanks again.

Thanks Rod....it did just as you suggested. 14 AC volts in and I dialed in down to 4.5 DC volts out. Maybe I can get these project signs done before the surgery on Tuesday.

Glad it worked as suspected Rick.

Nice videos by the way; and great detail work.
