The work
on the bench.
Hardware, firmware and the unglamorous power electronics that keep devices alive. Filter by discipline or open a build for the full story.
Power Inductor Tester
Power electronics · Lab equipment
A bench instrument that pushes current through a power inductor and shows where the core gives up. The case is together; the measurement is still being closed.
Airsoft Gun Controller
Embedded
A secure ATMega328 controller for an automatic magazine loader with OLED interface and motor protection.
Constant current load
Power electronics · Lab equipment
An adjustable MOSFET load for testing a dual-rail supply. One op-amp, a shunt and a potentiometer hold the current still while the voltage moves.
ZVS driver
Power electronics
Two spare STE40NK90ZD MOSFETs, three 1 µF tank capacitors and a coil of 8 mm copper tube — an induction heater built from parts already on the bench, then given a soft start and an on/off switch.
DRSSTC I
Power electronics · High voltage
A first Tesla coil, and a first DRSSTC. Started in August 2019, four dead bridges later, then a new secondary and an NTC so it can sit on the mains without a variac.
CTU SSTC
Power electronics · High voltage
A tabletop SSTC for Czech Technical University. It has to live in an 80×30×30 cm shelf in PlasmaLab, with almost no air moving past it.
DRSSTC II
Power electronics · High voltage
The large coil that was wound first and finished second. About 2500 turns on a 100 cm pipe, a UD+ with pulse-skipping, and streamers past a metre once it was tuned for the outdoors.
DRSSTC III
Power electronics · High voltage
A long-pulse coil. Pulse-skipping, on-times up to 3 ms, and a copper topload after the first one started hitting the primary.
