Don’t think flames coming out of this machine hasn’t crossed our minds

Need some LEDs for this? I take PayPal!
(Just for fun, everyone. Another forum asks for the worst rainbow puke LEDs ever seen on machines.)

Quoted from SickNate:I have been hesitant to make the playfield because I wasn't sure if my pop bumper design would work or not.
Well today I tested it and it works !!!!!
The design is 2" diameter pop bumpers instead of the normal 3". That way I can fit more in the same space.
When researching pop bumpers I thought they were over complicated with adjusting the spoon and all....
So I thought I'd take a stab at something that has been working perfectly for 50 years.
The ball is the switch. That is to say the ball closes the circuit that tells the machine when to activate the coil to bring the ring down.
The body of the pop bumper is polycarbonate .
From under the playfield I will light it with an RGB LED and hopefully the whole thing will glow whatever the LED is programmed.
Attached are some pics.
I cannot wait to cut the playfield now.[quoted image][quoted image][quoted image]
What voltages will you be using across the pop?

Quoted from SickNate:MD_Pinball_Dude,
I'm using Fast Pinball so 12v for switches.
I tested functionality with a fluke voltmeter set to continuity.
I put my leads from on the lower ring and the bottom of the "piston"
there was beep the instant the ball made contact with the rings.
The Fluke uses a 9v battery so 12v should work even better.
OK. I was just thinking way out into the future where you have had 1000s of plays on this machine and tens of thousands of pops. Where the ball touches the post and the base, there will be a very, very small voltage arc and over a very, very long time there might be a carbon (?) ring forming on these locations. You might want to add a diode across the two or a current limiting resistor if you find some weird things going on during testing.
Honestly, the pop setup looks damn near bullet-proof.

Quoted from epotech:No feedback on that router (either a rotary or linear encoder) and so it may be off and get worse as you progress the cut. Say it moves 1mm and so sends (say) 1000 pulses to the stepper, its trusting to luck that it actually does them. Make sure your router has some form of encoder.
And with at least 1100 counts per revolution on the tracking. (Electrical Engineer here)
