Small Constant Voltage or Constant Current Low-power DC Supply

John, that is a slick little board for chuff generate power supply; any idea of these being offered for sale?  You make trains fun! Falcon

I'm thinking I might make the PCB available or perhaps a kit to assemble.  I don't see selling enough to tool up and get this produced, for a board like this, that would be several hundred, and the tooling charges are around $300.  I'd have to sell a ton of them to recoup that investment.   If someone buys the Chuff-Generator, I could probably build them a board for a few bucks to power it.  Of course, with the Super-Chuffer, you already have power, no need for this board.

You need an index of all your goodies John.

I want a reserve copy of your first big grouping in a catalog if you ever go that route.

Besides simplicity, what's the advantage of half-wave rectification?  Is it useful to have outside rail the DC ground?

For TMCC, most of the signals are referenced to frame ground.  That makes it necessary for me to power stuff like the Super-Chuffer and my Chuff-Generator with a DC supply that has a common AC and DC ground.  For this simple low power supply, that seemed to be the obvious choice, and one of it's first uses was to power the Chuff-Generator in a stand-alone configuration.

I have other board designs that have a jumper for half-wave and full-wave for better performance when you don't need a common ground.

Pity the board isn't available.  I'm liberating an old MTH PCC from the horror that is LocoSound, and something like this would be perfect for running the 3v lights they put in for some indeterminate reason...

Mitch, anything's available for the right price.   I just haven't produced these in quantity as I don't see the market for a volume production run. 

How much is "the right price"? 

Mitch

Send me an email with how many you need.

Done and done!
