Hello,

I’m creating a BoM for a youth group project. We’re planning on building the Electromagnetic Ring Accelerator from Hyperspace Pirate. He’s provided the 3d print files, but not the finer details on wire gauge, enamel wire gauge and ball size. I also want to confirm the photoresistor. Are there different photoresistors with with different sensitivities or ranges?

I’ve included the wip of the BoM.

    I’m guessing you watched the first video, the one with a single coil, which, as you said, doesn’t specify those details. However, on a later video ( https://www.youtube.com/watch?v=uNbL3tRZeMQ ), where he makes some improvements to the whole circuit, there are some details mentioned in the description, such as

    Input voltage: 24V

    Number of coils: 4

    Wire Gauge: 24AWG

    Coil Current: 13A

    Coil ID: 1.1"

    Coil OD: 1.4"

    Coil Length: 0.5"

    Coil turns: 200

    The final outer diameter is ~2" due to the addition of steel wire to create a magnetic flux guide or “shell”.

    FET Type: IRLZ44N

    On time: ~8 ms at max. speed

    Energy input per pulse: 2.6J

    Ball mass: 65 grams

    Ball kinetic energy: ~0.52J
