I rebuilt the base and electrode mounts of the maglev ES motor, to match the new pencil-less armature. I am also working on an Arduino sketch for pulse motor control, and here I decided…
To complement the earlier video on inductance measurement by resonating tank, I’ll now show a slightly different method used by the Arduino inductance meter. The Arduino uses a bit of external circuitry to “strike”…
Here’s another SNOT update. This time I’ve cobbled together an Arduino data collection system. The Arduino monitors the gate signal from the SNOT controller circuit by the use of the pulseIn() function on pin…
Here’s the latest project, an optically-controlled magnetic levitator using the Arduino. The OSEPP Uno clone runs a sketch which senses the position and velocity of the levitated object, and sends a switching signal to…
The Copper-screen Grid is now electrically connected. I broke the system down and installed another feedthrough in the plastic base. For the feeds I am drilling and tapping a hole in the top plate,…

Based somewhat on a Jeanna’s Light or Lidmotor’s similar circuits, this is a lot smaller inverter than the one from the other day. It fits around the base of the 120V 2W Lights of…
One of the many Akula circuits, under construction. Testing the “output” stage which consists of one of the six inverters in the 4069 and the mosfet it is driving. I’m using the FG to…
When running, the inverter has no effect on the string of 15 series connected LED’s. See previous experiments about the ‘Pigeon Loft’ method of powering for a description of how the LED’s are being…
This is a two transistor inverter circuit for ‘Phyllis’ my plant battery. The circuit uses a small high voltage inverter transformer to raise the plant battery voltage high enough to light two LEDs. I…
