This is how I made my claw machine


Thank you all for all the views. Shortly I plan on uploading the blueprints and plans for my claw machine (seeing as how it is so popular and I have even seen some people flat out steal my design and idea for their own youtube videos anyway).

I would like to answer a few questions here that I have answered multiple times in the comments.

Q: How do you wire the cars to the joy stick?
A: I will be uploading the blueprints soon, but basically there is a (-) and a (+) for every electronically switch. I wired both the (-) and (+) going to the cars into both (-) and (+) on the switch. In other words it was the (- and +) of the car attached to the (-) of the joystick and the same wires attached to the (+) of the stick. That way when a direction was not being pressed the car movements canceled each other out and the cars stayed still.

Q: Do the cars need to be wierless or wired
A: You could use either. I bought cars that were wireless, however I ran into the problem of the cars not getting the same signal at the same time, which then lead to the cars becoming stuck and off track. So I converted them into wired cars with the exact same length of wire to make sure that they were getting the same signal at the exact same time.

Q: Why did you not make the claw close?
A: I chose not too because it was being displayed at an art show. The idea was that you could always try but never win.

Q: How can you make the claw close?
A: Attaching another car axle to the claw and installing springs to cause tension, thus giving some grabbing power to the claw and allowing it to pick items up.

Q: Can I make a REAL claw machine with this design?
A: Yes, you can, but you need one more componate, which is the controls to make it automaticly lower the claw, grab, relocate and turn off until another quarter is dropped into the slot. This can be done with a Rasberry Pi or other smaller programable chip.
Use this layout and program to board to allow the (+) to be activated when a quarter is dropped for 30 seconds. this will allow the user to more the claw. From there once the user pushes a button (also linked into the board), have it activate a sequence that will lower the claw, grab, and then relocate as if the time has ran out.

Q: Can you make another video of the machine?
A: No. Not because I dont want to, but because I cant. The machine was made for one day, and one day only. I built it at my house, tore it down and then relocated it piece by piece to the art show. After the show there was not enough time to disassemble it and transport it back, so I had to destroy it.
However, if you would like to make one yourself all the components are there and are easy to make. Trust me when I say you can spend less than $100 to make one. You could use light switches instead of a joystick for each direction (given that you would need two switches for each direction because of it requiring two connections to both positive and negative). Never the less, it can be done.
