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
I hadn't watched the second video yet. Thank you.
