    it was a three steps forward, six steps back weekend for the layout.

    On my bench I now have five very sorry looking turnout motors. Used 12v dc instead of the 16v ac power supply and had pretty much instant smoke. IMG_4481.jpg

    Oh No you let the magical smoke out. The smoke is what makes them work.

    Here is my latest workbench project. It is a multiple voltage power unit.
    I started with this.

    These are all the peripherals, that I snipped off inside the case. It is hard to believe that all of these were connected to the motherboard and passed through the rear of case with the 24pin pig tail that you see.

    This or something similar is what I am shooting for. It will have terminals for 3.3v, 5v, and 12v. I have found a kit that has an adjustable range from 1.?v to 10.? volts. Not sure which way I will go..

    This power supply came out of my oooold Dell desktop.

    Be well

    MK,

    thanks, it is not too late and I had looked at both of those. For time and to save chasing parts I may go with the 1st one or another one I saw that has adjustable terminal.

    You might have to use a resistor between the 5v and ground, I've built two of these, one on my layout and the other under my workbench. The layout didn't like the resistor and shut down however the benchtop power supply needed one.

    Looking at the min amp specs on the side of yours, I would hazard a guess that you will need one. Just be careful where you mount it, they get damn hot.

    If I'm reading that right, you mean that the resistor gets hot. If that is the case, be sure to look at the voltage/amperage specifications for your resistors. It might be better to oversize it and buy a higher wattage resistor that is designed to dissipate heat. I've played with 120 volt one Ohm resistors. For one Ohm, they're still as large as your index finger and can be even bigger if they have fins to help shed heat. Obviously, something like this wouldn't need *that*, but you get the idea.

    Does anyone know the voltage spec range for the atlas twin solenoid switch machines? I have an old power supply that I used when I was a ham operator, I have to dig it out to check the voltage ratings but 13.8 wouldnt suprise me at all --- I would like to get them running temporarilly till I can get my servo controllers and mounts built

    Pastor John,

    Yes, I plan on a resistor. the build that I am following used an 8 ohm 50 watt finned piece. He said "you can use smaller", but if this is good for him it is good for me.

    Be well,
    Carl

    Currently what's on my workbench is a bunch of junk.
    One of my swappable industries that fits on the end of the peninsula that is "Port Eureka".
    Each industry is built on a 1.5" thick sheet of foam.

    The above is a truck to rail transfer station for various recyclable fluid waste products.
    [​IMG]
    Lots and lots of junked cars with a REM crane with magnet to load them.
    [​IMG]
    Here's the other end. The Quonset hut is a printed paper model and the auto crusher is scratch built.
    [​IMG]
    More junked cars from various manufactures.
    And yes, I painted them all.

    Well my workbench once again has non trains on it :(. What makes it worse this time is my truck is getting a new transmission and transfer case so I can’t put my new goodies in it. So here is a bit of showing off, for the goodies my S10 gets when it gets home next week.

    And last but not least, the double din installation kit that will make my new radio fit the truck

    I got speakers too, but no pics.
