Just building up the kits, there is quite a few parts.....

How to build - I did a quick pdf:
construction instructions.pdf

I've adjusted the output of each voltage regulator board to 5v.
I've flashed the latest firmware to each of the EP32s MPU boards, and tested each one. V2.05
I've tested each LCD display and adjusted the brightness.

8 Kits all ready to ship.

Kits - £60 GBP plus £20 International tracked/signed postage. So total £80 GBP.

I also have one fully built tester - GBP £100 + £20 Shipping = £120. (I can possibly find time to build one or two more out of the kits)

I have been through my messages and the replies on this thread, and taken requests in order:

On the list so far:

Anyone above, please message me with your email address and I will send a paypal request for payment.
(Would appreciate a friends/family payment to reduce paypal fees, if you are happy to do that please?).

If you no longer require, please let us know and I will offer to the next people:

Waiting list:

Many thanks to all who have expressed interest.

Most of the items have now been despatched. I had a question about how to test the tester, if you are building from the kit:

Once you have built the kit, and have checked everything is soldered up and placed correctly:
1. First do a bare test with no Lamp driver board connected. On Powerup the LCD should display the welcome screen and direct you through the tests.
2. Test a known working lamp driver board.
3. Then move on to testing unknown boards.

Check any lamp driver board for any obvious faults before testing, e.g. cracked header solder joints, broken header pins , dirty header pins, broken traces, missing or damaged SCR's, etc. Poor header connections to the testers LED display boards can result in incorrect test results. As you all know, headers should really be re-pinned !!

Be aware that a lamp driver board that has a short on the 5v to earth - will short out the power generated from the tester, so just watch out for that - symptoms are the tester hanging up or rebooting, the voltage regulator board components getting warm! Fix the shorted board before re-testing.

Any questions or issues, I am here to support.

Quoted from AlanJ:

Ok folks, I've had two requests for these testers in the last few days (thank you I do appreciate it!). So, I will consider another run of 10 units, assuming we can get a bit more commitment? Anyone else in for one?
Fully built & tested and working, £100 GBP + Shipping £20 International Tracked and Signed.
Kit format - all parts provided, firmware flashed to the ESP32s board (you just need to solder & crimp a few wires), £60 GBP + + Shipping £20 International Tracked and Signed.
Alternative delivery: Economy Delivery (not tracked, so at your risk) £8.

I would be up for a kit.

Still awaiting new parts, there is a bit of a delay in getting them.

Talking about Bally / Stern test kit - I am just designing myself this:

pasted_image (resized).png

It is an 8 X 6 switch board, so I can test a Bally or Stern MPU switch matrix without having to plug it into the cabinet or playfield. i.e. can test on the bench.

Each switch is a latching switch, so can simulate switches that should be closed most of the time, e.g. the ball trough switches on multi ball games, such as centaur, fathom, Fireball II etc.

I have put a LED under each switch so that the led indicates if the switch is closed or not.

This means the board needs power to drive the LEDs, so it has a 5v power header at the top as well as a header for the rows and columns.

I have a also designed a very handy MPU J4 intercept board:
This allows us to grab 5v power for the leds, and more importantly also allows us to access the "column 5" switch strobe data line which is inconveniently on J4, rather than J2 with all the other switch rows and cols.

I also stuck a 12v output on the top as I have a use for that in other projects. (e.g. to derive an additional 5V power source without overloading the SDB existing 5v supply).

I'll get some extras produced, if anyone can make use of these.
