Simulating a Pinball Backglass [PAID GIG]

I would love to be able to take the time and learn Arduino platform and build exactly what I need, but alas, only so many hours in a day. Hopefully a skilled member of the community would like to help, for pay of course.


I have a 1979 back glass and cabinet for a Gottlieb Incredible Hulk pinball machine All the original wiring, bulbs and boards are still inside. My original intent was just to power it up, decapitated, and use it as wall art and add a switch. Unfortunately, the score displays are probably blown and when it was decapitated someone just snipped the harness that leads to the playfield. Probably wouldn't light without the full circuit.

I found this while researching how I might light it. Seems legit and would cover the purposes of just lighting the glass. However, I want the score displays to light too. Doing some more research led me here.

What I'd like to do:

Make a random LED bulb string similar to the AIRFIELD with (x40 individual bulbs)
x4 six digit (blue or white) seven segment displays (random numbers)
x1 four digit (matching) seven segment displays (random numbers)
Toggle switch power source running to 110VAC

All parts would be purchased obviously, let's talk rates.

This is my first post here, but I thought I would chime in.

We have a community of hardware engineers who offer services geared towards helping other hardware developers. We charge $60/hr. Engineers have experience from 3M, Samsung, NASA, and more.

Shoot me a message if you're available.

I think an Arduino and a series of 5 MAX7219s would fit the bill hardware wise, drive up to 64 LEDs from 1, and the 28 digits from 4 more (8 digits each). All LEDs & displays are common cathode type.
All could run from a 5V switching regulator wallwart.

You don't say what size digits, any digits that are single LED/segment would work. If you want larger digits with 2-3-4 LEDs/segment that need say 12V, then a different driver solution is needed.
I have a board with arduino function and 12 shift registers that can control 12 higher voltage displays; it is arduino based and can be daisy chained:

This Nike fuel band display uses 2 boards to drive 100 12V LEDs:

My rate is also $60/hr and I have completed many Arduino projects for folks here in the forum.
You can see more of my board designs here.

Thank you both for responding. I realized after reading CrossRoads response I need to provide a little more detail. I still need to fabricate the backer that will hold the board and measure space for cutouts for bulbs and displays. I will make a schematic tonight, with measurement so you can see how much wire you'd need, and voltage based on the size of the number displays.

I'm all about this project and really, really want to get this done. I will post the schematics back public but also will message you both since rates are the same and just want to talk directly about it, once the schematic is done.

THANKS FOR GETTING BACK TO ME GUYS! :smiley: :smiley: :smiley: :smiley: :smiley: :smiley:

Happy to help and looking forward to the Schematics :slight_smile:

Alright, here is my rough schematic sketch of size and placement.

Ok, I'm thinking a control board like this, and 4 remoted large digit boards.
Control board as pictured is 4.65 x 3.3".

Can remote the small digits too.
Ribbon cable to connect them all.
LEDs with 2 wires plug into breakout area to place where needed.

Adjust sizes as needed when digits are selected, examples:
