Coil Right There: 2 Circuits Running a Third Room Still for Growth

Hook

Hey folks, Papa Bale here. Got two circuits running on this wheel and there’s still a third room for some growth. The coil right there on the bottom is what my meter is hooked to so we can watch the surges. Come see what actually happens on the bench.

Watch this experiment

I fire the whole thing at 4.5 V then crank to 9.2 V. You see the cap bank LEDs light, the wheel spin up fast, and the meter on that bottom coil jump to 61 V AC before settling around 20 V. Two different coil sets, one siphoning BEMF into the cap bank, the other still waiting to be yoked.

What you'll learn

You’ll see exactly which gauges are paired, how many coil slots are active, what the power supply reads under load, and why I think the 32 gauge coil picks up a stronger imprint. All straight from what happened today, no fluff.

From the bench

Power supply set to 9.2 volts, pulling 420 milliamps with both circuits running. Cap bank lights are getting brighter, rotor is moving really fast. Meter hooked to the black coil on the bottom catches 61 V spikes that level out near 20 V. I had to glue the magnets because at speed they start to push forward. Everything is a little flip-flopped on the breadboard but it works.

How it works / what we changed

Two separate circuits share the same wheel with four magnets. One circuit uses a 20 gauge coil with its 30 gauge trigger plus a 24 and 28 gauge pair in series. The second uses a 20 gauge and 30 gauge with a 26 and 32 gauge set. I’m taking BEMF off one set and shoving it into the cap bank that has AC caps on one side and DC on the other. The plan is to eventually yoke the second set or add the remaining coils for more torque.

20 gauge coil

The 20 gauge coil is the main drive coil on both circuits. One is paired with its 30 gauge trigger and the other sits with a 26/32 gauge set. It’s the thick wire that carries the main current and leaves gaps that finer wire can fill for pickup.

30 gauge coil

I use 30 gauge as the trigger coil for the 20 gauge drive on both sides. One 30 gauge trigger is on the first breadboard half, the other is paired with the second 20 gauge. It fires the transistor and stays thin so it switches cleanly.

32 gauge coil

The 32 gauge coil is paired with the 26 gauge on the second circuit. I say it works better because there’s more surface area to catch the magnetic imprint from the passing magnets. You can fit 15–20 wraps of 32 gauge in the gap of one 20 gauge strand so you get more turns and higher meter readings even if the raw energy isn’t necessarily bigger.

Coil slots

There are eight coil slots on this wheel. Not all the coil slots are hooked up yet. Right now only four positions are active—two circuits, each with a drive and trigger pair. The plan is to maybe hook the other four in one single circuit so they fire together on the off beats and give more torque and spin.

Builder checklist

• Wheel with eight coil slots, four magnets
• 20 gauge drive coils (2)
• 30 gauge trigger coils (2)
• 24/28 gauge series pair and 26/32 gauge pair
• Breadboard with two separate circuit halves
• Power supply able to run multiple devices
• Cap bank with AC and DC caps
• Meter hooked to bottom black coil for AC spike reading
• Glue gun ready for magnet security

Troubleshooting

If the magnets start pushing forward at speed, glue them down. When the cap bank caps blow from too many amps, replace them; I’m not putting blown ones back in. If the circuits feel flip-flopped just keep testing connections until the wheel spins smooth. Frequency changes when you start siphoning harder, that’s normal.

Safety

Keep amps reasonable so you don’t blow the DC caps. The cap bank lets some DC through the AC side but high amps still cause damage. Wear eye protection in case anything flies off at speed. I cut power quick when I had to reach over the spinning wheel.

FAQ

Why does the 32 gauge give a higher reading? More turns fit in the gaps of the 20 gauge so the magnetic imprint is stronger on the finer wire.

How many coil slots are actually used? Only four out of eight right now; the rest are empty for future expansion.

What voltage and current are you seeing? 9.2 volts and 420 milliamps with both circuits running and the cap bank charging.

Are you really getting free energy? I’m siphoning BEMF into a cap bank and watching the meter; it’s real surges but I’m still learning what it can actually run.
