Parker Dillmann of Longhorn Engineer reports he’s just finished the Rev0 of the Tommy Pinball System:

Just finished Rev0 of the Tommy Pinball System. I will be uploading the Eagle files after I can confirm the board works. It is a 4-Layer board so I will be using Seeedstudios new 4-layer prototyping service to order some boards. After I receive them I will allow some people to purchase at cost a fully assembled board for testing and code writing.

  1. Mmmm… It looks very sparse,

    Why is a 4 layer board required here? It seems like most of the logic is routed on a single layer so I suppose that there’s a ground layer and a power layer, but high current drains like the solenoids probably should have their vcc/v+ supplied at (or close by) their contacts anyways so a supply plane seems a bit unnecessary.

    I’m sure there’s a good reason, but with no schematics it’s a bit hard to tell.

    Maybe it really doesn’t matter if the PCB is $5 or $25 each in production costs if the rest of the parts for the complete unit costs 100x that.

      Good question Mats. You are pretty much correct. In production the 4 layer board is only a couple dollars more then the 2 layer board. A 2 layer board would be a couple square inches larger to (have to spread parts out more) which increases its cost.

      Plus routing a 4 layer board is just easier :)

      I will be uploading the schematic and layout (eagle files) after I verify that the board doesn’t catch fire.

        four layers also mean you will need a paid version of Eagle, but I guess it doesn’t make much of a difference since it is also too big for the free version

    I was interested in this project from a long history of involvement with Pinball machines, but I have the classic question – what is this, and what does it do? I’ve been to your website and looked through various pages; lots of discussion on the status of the project, but I’m none the wiser. Do you play pinball on it? Is it a controller for old pinball machines? Does it even have anything to do with pinball machines?

    I don’t mean to be a downer, but not being able to figure it out is a bummer.

    • Parker says:

      Understandable! There is very little info on my site about what it is (I need to fix that).

      The system is designed for people who what to build a custom pinball machine. You can also refit (reskin) an older game as well but you will have to rewire as the system only supports LED lights. Low cost (compared to competitors) is a goal as well so that some of the up and coming “boutique” pinball manufactures might like it.

      Personally I have been working on a pinball machine for awhile now and decided I wanted to standardized the hardware before I continued with the layout and artwork.
