Just wanted to say thanks to everyone on this thread, especially HurryUpPinball for the how-to videos and AUKraut for making the GI relay so simple.

I made one set of these for my High Speed restoration and still have all parts needed for a second set. Everything required for 2 sets was less than $100. It took me about 2 hours to make them.

That said, if anyone reading this thread is wondering if they would be able to make these, the answer is yes! Seriously, don’t pay for the PinStadium ones. It’s great that they came up with the concept, but $300 a set is absolutely criminal. I used to have a MBr with a set of the real ones that were purchased by a previous owner. This set I just made is basically identical.

I’m certainly no electronics wizard and if I can do it, you can too!!

Thanks!

Here are the relays I bought:

Correct, J1 is the trigger. I just picked a nearby GI lamp and connected the black alligator clip to the ground and the red to the other. Most important thing is to make sure it’s a GI lamp.

You bet! Getting these lights to switch on/off with the playfield GI was what held me back from making them long ago. AUKraut came up with the simple relay design and it works perfect!

You’re videos were great, I played them on my iPad while building the rails and everything worked perfectly!

Here’s a question for anyone that’s using a relay:

I didn’t want the relay just laying in the bottom of the cab unprotected so I put it inside this small electrical box. What are you guys doing with yours?

For my next one I’m thinking about sealing the relay in heat shrink after I wire it up. Anyone think that could cause a problem or have any other ideas?

Gotcha, good thinking! I’ll be doing that on the next one. I’ll probably also re-do this one. The heat shrink gives it a cleaner look.
