    The man takes apart a pc power supply for HO scale power needs.
    &$^%&^ GENIUS! I always used a 6 bay power strip, with a ton of random ac to dc adapters for the various bridges, lights etc.
    By making a secondary board with some resistors, relays and switches, I can have my power needs in one place.
    Im gonna start thinking out the box more.
    Well Done

      Hi Mike, Ron told me that you model your layout with Kato, I had asked him if he would caulk or hot glue to mount Kato track, he thought hot glue but suggested I ask you.
      I’m about ready to secure my Kato down so I thought you might give me some advice on the best way or your way how to do this, like under it or along the sides???
      Not sure if you have any tutorials on your channel (I’ve never seen it but I’ll sure plan on it if you do), thanks for any help that you might be able to give me in this matter. Ron J.

That computer died last year after 14 years of service. I kept all of the components that are still usable and now I will use one of the power supplies after we move to a new house later this year and I build a new layout.

    The circuit board, itself has labels for the specs of the different components on the board. They are marked next to each component, though the info is limited and can be difficult to read, it can still be of some help. Power supplies from old or crashed game consoles can also work well for electronic projects. I’m converting a power supply from my crashed XBOX 360 and attempting to convert a first generation Xbox power supply as well.

The video that I have been using for inspiration is by the great Joe Desmond and his Central Jersey Conrail in N Scale - 'Installing ATX power supplies on the Sayrehurst Secondary'. However, what I am considering purchasing is an ATX Power Supply Breakout board (available from Amazon and other places), which seems to make it so easy - just plug in the power supply sockets and the breakout board supplies all the screw terminals, all labelled for the various voltages. Just need to do some more research on these...otherwise your method will be the way I will go!

      I build power distribution for the US Navy and Disney Theme Parks. For this application GKEEMARS wire connectors are better than WAGO. WAGO has their application here as well but the GKEEMARS are in line couplers and splitters which improve the wiring ergonomics or routing flow. They are also much less cost than WAGO. I use both. It eliminates the crimp on spade connections, the foolish slot screws that can vibrate loose and leaver nut technology allows for different gauges of wire to be clamped independently. You can also write on them to know what their purpose is. They also provide easy patch ability if altering your layout.

    You are able to get +5v, -5v, +12v, -12v and 24v all from a computer power supply as well as the possibility of a few other voltages. The 24v power is obtained by connecting directly across both 12v connectors. One of the much older AT power supplies also gives the same voltages but through a different connection with two wire bundles on an AT power supply.

  • @yuryschkatula9026
    @yuryschkatula9026 Месяц назад

    Be careful just "connecting all wires of the same color", not every power supply would tolerate this (however, most of the old ones would do). Reason behind is simple: sometimes, you would find a schematic with several electrically separate circuits for, let say, 12 volts: so you have wire group "A" with 12.1 volts for instance, and wire group B with 12.2 volts just because they are two not-the-same electrical blocks inside the same metal box. Once you bond together both "A" and "B" wire groups, you short-circuit the potential of extra 0.1 volt. Yeah, this is a small one, however it would be dissipated somehow due the Ohm law etc., causing extra heat around and shortening the lifetime of your power source.
