Hi all kind of a newbie question here so please be patient with me. I've got several mods I want to install on my machine (Dredd) but I had a bad experience previously using alligator clips and I would prefer to use the two pin Molex style instead. I've been looking for something to power them all and I came upon This combination, would this be a good solution? If not, could anyone suggest something better? Thanks in advance

User "Dumbass" here on pinside offers a made-to-order Williams WPC External Power Supply Board

https://pinside.com/pinball/forum/topic/dumbass-test-and-reproduction-pcbs/page/4#post-5911232

Uses a standard 12v power supply brick as input and outputs 12v and 5v as standard WPC style headers

Takes the mod power draw off the WPC boards completely'

Hello, I'm going to closely follow this topic as it interests me a lot. I make my pinball toppers with USB-C connection, and I'd like to know the best way to connect them directly to pinball machines. Thank you for creating this topic; I didn't know how to ask.

Quoted from SUPERsolenoid:

using alligator clips

Yeah, that's just a bad idea. The auxillary board someone else linked is probably the best option, but I've always found an appropriate place to tap into, and soldered wires rather than trying to use alligator clips.

Thanks so much for replying. I'm feeling a little bit thick as I can't seem to understand how a 2pin Molex connector would interface with that board you referenced? Please enlighten me, thanks again man

Anyone have any more wisdom to share on this matter?

What are you actually asking? I've I were not selling mods, and I already have a desired power supply (5V,12V or 48V), I'd just strip some wires and screw them directly in the terminal where you can screw in wires. On the mod side, you can just solder them in and tape off the solder joint so it doesn't make contact with some other metal parts.

If you want each one to be plug and play you can have as many wires as you want connected to a jumper that goes to the power supply. Can crimp off or just solder directly to the power of your mods. Diagram below is one lead wire screwed into the screw. A solder joint making 3 more leads. 1 lead is crimped, one nothing on it and the other soldered directly to the mods power.

Here are some crimps and you can get 2.54mm housing for them also.
