Caramba, que ideia ótima em utilizar as bolas como parte do circuito. Assim diminui os casos de manutenção, fora que fica mais limpo o visual. Vou adotar em meu projeto. Parabéns pela ideia!!
David Ribeiro that was carved out of 3/4" acrylic sheet. I think I have a video here somewhere of my homemade CNC machine cutting a wooden version of one. my idea was to find a good way to create a pop bumper without buying actual assemblies. this one triggers a TIP120 transistor to fire the coil when the ball completes the circuit between aluminum post and base.
Very crafty!! I´m creating a whole pinball machine from scratch and I was having problems designing the bumper. Your idea is simple and works very well. I'll create a prototype using your concept and let you know. Thank you for the information! =)
David Ribeiro very cool. I want to do that too. I actually started designing a larger play field test bed that will keep sending the ball back in play. It will have three removable areas that would hold some kind of feature that interact with the ball.
I am not sure why they use cup leaf switches in commercial games. I guess in games like TZ where there is a non-conducting ceramic ball, or those with plastic balls to change game dynamics, this design won't work. Perhaps there is something in electrical standards preventing this kind of design, not sure. I do like the idea
Pop bumper test 2: ruclips.net/video/VeOXLYzelEM/видео.html Not too bad. I want more pop though. The coils are 26-3000. I stripped down some wire which drop the resistance to 26 ohms or so. I'm thinking I want around 10 ohms. My circuit will withstand 20 amps at bursts. I have a 2 amp fuse in line and its not blown yet. After the power is where I like it, I'm going to make a few more and create a larger test jig. Next one will be flat. This one is 1/8" lower in the center so balls well end up there.
Tommy Steve the wood is oak, the clear part is acrylic sheet machined on my CNC. The disc in the center in the wood is aluminum, the post is aluminum, the sleeve is plastic. The aluminum post is threaded to steel plunger that goes inside the coil mounted below. The ball closes the gate on a tip120 transistor to charge the coil with 50volts.

I have a feeling this is going to blow up at any moment, if not, why am i here?
I am curious if a long term test will show degradation in conductivity due to dust, corrosion etc.
May I ask what are you using as a flange? (the plastic conic part on top that pushes the ball)?
Thank you for the demonstration!

But want the curent flowing through the shaft slowly corode it? Will the oxidation prevent a good contact later?
@@davidribeiro so, hows the progress?
Awsome

It's perpetual motion!

Where did you get it?
Tommy Steve I made it.
