Lidmotor inspired 1.5V Perpendupetulum pulse motor charging a 9V battery!

Powered by a single Songle 3V hacked relay coil (about 20+ Ohms), this little pulse motor has also been running for many years. Found the Perpendupetulum pulse motor circuit on ‪@Lidmotor‬ Took me a while though to figure out I could use a small Nescafe lid on a rusty nail, with a tiny bit of butter between the nail tip and the center of the lid to minimize friction. Spinning at about .400rpm on a 1.2V NiMh AA battery. The AA drive battery lasts 3 to 4 days. Best I managed was 6 days!! Having experimented with Bedini circuits, I thought I'd add a charge battery to store some of the back emf. So I disconnected the 3mm green led leg from the +ve of the circuit, and added the -ve of the battery to the +.ve of the circuit, and the +ve of the battery to the free led leg. More of a trickle charge as the circuit uses so little (-10mW)!! The led still lights dimly with a 9V battery. Changed a few values from the original circuit over the course of time. Had to decide between torque, speed or economy.! eg a 3V 4700uF cap in place of the 2200uF, 2n3906, 2n3904, 1n5822 I swapped the two 100k resistors for two 100k pots which I tweaked (for easy starting) and then back to fixed resistors with the pot's values. I also replaced the 330R resistor for a pot as seen in the vid, to control the speed and thus the economy. The Nescafe lid has 6 round neo N35 magnets NN on the outside and 6 on the inside. After adding a further small rectangular magnet on the back of the coil (enveloped by BluTack!) the magic started!! Using only the long edge of the magnet, setup to attract the incoming lid magnet, and repel it after being pulsed. Incredible circuit that runs so well off an AA battery, right down to 0.7V! At 8pm on Tuesday 23rd April I replaced the AA battery I was using (and spare), with D size batteries (10000mAh Fujicell NiMH) that I had forgotton about for years, and that "couldn't" be charged, until using my Bedini Rene charging circuit!! Already spinning for 3+ days seemingly stationary at 1.27V!! The other D size battery is being charged and is at 1.404V, with the led nice and bright indicating a healthy charging current! Sunday 8pm 28 April - Drive battery at 1.269V and Charge battery at 1.390V. Thursday 8pm 16 May - Drive battery at 1.220V and Charge battery at 1.352V. As the Nescafe lid has slowed down a bit, I have changed over the batteries!! The charge battery might have been higher, if I had noticed it's dodgy connection earlier. I'm very pleased not having to charge my old AA's every 3 days!! Similar to the Perpendupetulum circuit is my Solar Pulse Motor but without capacitors. They seem to be distant cousins. They both use very little, and only one coil to detect and repel a passing lid magnet. One uses a 1.5V battery and the other a Solar Panel or battery between 9V and 30V. Cheers Roberto.
