I'd like to do this, but the instructions are a little sparse. There's no part number for the relay or the little bread board he uses, so I'm not sure what they are. Anyone done this and have more detailed instruction?

What Leon writes is right, I'v had a few theatre's with this behaviour.
Though the pinbits auto eddy boards seem to solve it often too.

It says that's for outlanes, but does not work on the trunk.
I figured out the answer to my original question though. I can zoom in on his picture in the article, and was able to pick the part number for the relay off the part. I ordered a 2 pack of the relay for 8 bucks all in on ebay. And then I ordered a small pack of bread boards, so I should be able to build this thing (actually, 2 of them) for 15 bucks all in. Which is awesome, it bugs me when the trunk gets weird.
Edit: I see you figured it out while I was typing. Good luck.
The relay is triggered off 12v, you can see it on the picture. It is a 24v relay that can handle 8A at 250v although this is way more than necessary for this setup. The board is just a standard breadboard. You can get them at Radio Shack if you still have one near you.
He connects the relay in parallel with the trunk motor. This way when the motor is running it energizes the relay. When the relays is energized it opens the contacts for the eddy board, which means no ball hits can be sensed.
Connect the relay's coil contacts to Pins 1 and 4 of J2 on the motor control PCB. This will allow the relay to energize when the trunk is moving.
Now hook up one lead of the eddy sensor wiring to the normally closed contacts of the relay. These contacts will be opened when the relay is energized by the motor so that it can't sense a ball. The wire you want to run to the NC contacts of the relay are Pin 2 on J1 of the eddy sensor PCB. You are basically running this wire into one NC pin on the relay and back out of the other NC pin and back to the eddy board.
The connectors on the breadboard just pass the power either to the relay, or directly through from one pin to the other.
I thought this one http://www.pinbits.com/index.php?main_page=product_info&products_id=375 but seems to be sold out.
But indeed Leon's bord will solve it 100%.

Here is a linkt to the datasheet of the relay:
http://www.datasheetarchive.com/dlmain/Datasheets-20/DSA-388631.pdf
As said, the relay is oversized - this one is not so expensive:
Important: Do not forget a flybackdiode over the relais coil!!!! It looks, as Leon forget this.
Very interested in this board fix. Let us know updates when you have them - would love to have one of these myself.

The idea is form Leon (RIP) - a really great guy form belgium.
I only made the new layout, to help EvanDickson, the thread starter.
But unfortunately there came no response.
Only thing, I can offer you, is to etch you a board and put all parts on it - if you want.
I thought about the design a bit and made a new design. I do not like the way, Leon fastens the new PCB to the trunk-opto-pcb with only 1 screw. In my new design, you use both upper srews of the trunk-opto-pcb. I alsi rearragned the connectors, so connecting the cables is more easy and fits better imho.
Unfortunately I do not have a TOM for testing.
But fotos say more than words.
Quoted from njgsx96:I would definitely be interested in this as my TOM has the same issue.
OK, no probelm for me, to make 1 or 2 boards.
But you could do me a favour. Please measure the length for the 2 new cables. As said, I do not have a TOM. In the following foto I need the length of the 2 yellow marked cables. Please take a wire and measure a comortable lenghth, not too long but also not too short.

Nice designs change - that would look very clean over the opto board. I would estimate the length of the wires as about 7 inches/18 cm each. I will send you a PM.
I would be interested too in this.
A set of extra cables with connectors so this is a plug and play set would be a huge bonus.
Greetings from Belgium.
I am interested in this fix as well, Someone just need to tell me when they are ready to ship.

Maybe someone can be more exact than me, but here goes. Distance between the two mounting screws, from center to center is 60 mm. 4.9 mm looks about right for the holes. Diameter of the nuts is 10 mm.
I would like to purchase one also from you ... the more plug & play ... the better for me! THANKS for doing these if you can.

I'm interested
I cannot for the life of me find a ruler with mm, and I know I have one. But using what I found, it looks to be 2.375 inches from center to center (60.3249999mm). I agree on the length of wire posted before. I think ~7" would be a good length.
I will keep looking for a better ruler (and one for the metric system too for you). hope to post later tonight if I find it.
Wauw, looks really great.
And love the tribute to Leon. I've met him in person a few times and was a really nice guy.
Quoted from DavidPinballWizz:And love the tribute to Leon. I've met him in person a few times and was a really nice guy.
+1 Nice to see tribute on the pcb! Did the same thing with the "Sys80 Universal Tester" board that I offered to the community. I'm sure he'd have been thrilled that his projects continue to inspire new ideas & boards!
I also like "THE ULTIMATE"
Hey, this thread really took off since I thought it was resolved. A specific board, that's awesome, German-Pinball. And I love that the required parts are labelled on the board! Any idea on the cost of the product?
Thanks,
Evan

As there are so many interests, I have decided, to finally let produce professional boards. But at first, I will etch this weekend the prototype and send it to "canea" for testing.
The more boards I let produce, the lower the costs for each pcb:
10 pieces / 12,00 USD/each
20 pieces / 6,00 USD/each
30 pieces / 5,50 USD/each
50 pieces / 3,60 USD/each
The rest are the molex connectors, the relay and 1m=42,5inches wire.
Depending on how much pcbs I let produce, I think, the price for ALL parts will be about 12-18 USD.
As far as I see, we now have 10 intersted people - 20 would be good, then the price for each pcb is the half compared to 10.
If I ship the spare board only, you should take yourself care about to get the parts with, but have extra shipping costs from the parts distributor or so. Best would be, I get all parts, so the set is complete and I ship as a DIY-project or complete assembeld, as desired.

PS.:
What is with the control-LEDs? Are these desired??
How thick are the wires, AWG20 ????
Quoted from zaza:Hold on a sec.
Am I correct that this PCB is connected to the exit of the BI-DIRECTIONAL motor control PCB A-16120 ?
If so, then I would suggest not to install D1, the L6203 would not like that.
LeonsRIPMMTB TEH fix.jpg
Thanks for the hint, I will check it!!!
Don't have problems with my ToM now, but if you all are telling me there is a common problem, then perhaps it's only a matter of time.
In that case, I'll take one just to keep as a spare, since ToM won't be leaving my lineup anytime in the foreseeable future..
Awesome, sign me up for one too, then. I'll keep the parts I have already ordered as spares.
Thanks,
Evan

@zaza:
You are absolute correct, it is connected to the BI-DIRECTIONAL pcb A-16120 and the L6203 would not like that
What do you think of the following solution, so we have an effective back emf protection for motor + relay-coil??
If Leon's modification worked without a diode, then the L6203 is likely protected against voltage spike.
In the L6203 datasheet there are 2 diodes per channel so it looks like it won't need external diodes.
Maybe someone with knowledge about electronic components can give a more decisive answer.

@zaza:
Thanks.
Yes, Leon´s mode worked without diodes, but we want the absolut perfect layout.
Your excerpt from the datasheet show the 2 inner diodes work as freewheel-diodes, so that there is protection against cross conduction.
But datasheet also says "Although the device is protected against cross conduction, current spikes can appear on the current sense pin due to charge/discharge phenomena in the intrinsic source drain capacitances".
So EXTERNAL freewheeling diodes would prevent current flow through Rsense and relocate power dissipation to "outside".
Same datasheet shows this with external diodes:
Here, they are also shown:
http://mech.vub.ac.be/teaching/info/mechatronica/finished_projects_2010/groep2/electro.html
I am a bit unsure now, but ihmo, these diodes are not absolutly necessary, but it doesn´t hurt to have them (we would have additional protection). And as we are in modern times in these days I would not use good old BYW-Diodes, but schottky diodes e.g. SB3100.
But we will see, when the prototype is etched, we can test with and witout diodes.
Quoted from Kiwipinhead:I will take one also
Me too ... So that's two for New Zealand. My TOM trunk stops all the time.
