Thomas the tank engine. TTTE.


Recommended Posts

I've just done something very stupid.

I used the words Thomas and pinball in the same sentence in front of my three year old son.

I might have to start selling some projects and just work on the AA and now Thomas pins.

The Thomas one will be just an Arduino running a Hankin/Homepin solenoid board.

Edit: As is usual in my projects this idea has changed.

It'll be very simple and built on an old Orbit1 or Top Score playfield.

I might have some cheap cocktail cabs for sale soon and I might just check the boards in the Phantom and sell them and the cabinet too.😉

Cheers Trev

I've rebuilt my old discoloured Orbit1 playfield with Gottlieb Pop Bumpers, Data East Slingshots (from the spare Phantom of the opera playfield) and a few Hankin bits. After the playfield was assembled I checked the power supply I bought for the AA pin (on hold for a while) to see if it would fire the solenoids ok. I just wired it to a coil with a push button in the positive line.

That worked fine so I mounted the psu, an Arduino Mega and two 4 way Mosfet boards to the underside of the playfield and started to wire it up. Once the solenoids were wired in I moved on to the switches. I still have the +5v (common) line to add to one side and the flipper wiring to do and the start button. One wire from each switch goes to a digital pin on the Arduino and a pulldown resistor and the other wire on each switch is looped together and goes to +5v.

Flipper switches will switch the +5v going directly to the mosfet board so won't need to be heavy duty and I can use a low power relay operated by the Arduino to turn the flippers off while it's in attract mode. All the lighting will be handled by one string of addressable leds driven by one pin on the Arduino. (I love that idea)

Yes it's in a Getaway HS2 cab.

Day three.

I knew that hole was there for a reason. Hmmm. Smoke machine maybe.😉

I've ordered 1.8" high blue 7 segment led displays for the scoring and balls in play displays.

What a great project, Trev. Will you have it ready to bring to Pinfest so Christopher can show off his skills? :)

I hope so if I can get it to work properly and if there's room. I've got a bit of programming to do but it's going to be a simple game.

Whats the mofset driver boards your using Trev? What input voltage do they need?

They take a 5v signal from the Arduino and will drive 24 to 28v for the Gottlieb and Hankin coils I'm using. They are IR540 mosfets and can supposedly drive up to 100VDC at 33A or so the Ebay ad says.😉

I will be changing the common line on the switches to gnd as the Arduino Mega has internal pull up resistors but doesn't have pull downs which I'd need to use the +5v as a return line.

just get an old working EM with crap playfield and put some Thomas decals down for a playfield and on the plastics, couple of Thomas toys and be done with it lol

Is this what you mean @jason1?

Day 4.

I mounted the flipper switches, glued the chimney together, bolted it to the back box, mounted the relay board, wired up the rest of the playfield switches and fitted plugs to the switch cables. f5fbcdf8fba31a5ce05a350cb0e3bdd3.jpg186ecf5e1ea930e59d63a310cc738591.jpg20675e0dfd8962e22cbd04ee96e8c7d1.jpg

I still need to wire the flippers which will have +5v going from the psu to the relay board through normally open contacts to a common on both flipper switches with a second wire from each flipper going directly to the inputs on the mosfet board.

I've found a 5v 15A PC power supply for all the 5v supplies.

I'll need another relay to operate the topper lights 03d91a2ee15dbd91a244b74d438fd215.jpg

and two for the toy trains on the playfield.😉1b1cc3f5faeb216154b222e58f1c4a45.jpg

I might need another relay.

Those small units cant handle much work... they are usually only capable of pumping out smoke for 10 seconds, then it will stop for like 2 minutes.... you'd need at least a 1500W unit if you want it to work every single time you tell it to pump out smoke, or if you want it to blow out smoke continuously.
