8000FPS Slow Motion Tesla Coil Spark Formation and Collapsing Hot Spots

Leave a Comment / Slowmotion, Tesla Coils / /

Slow motion Tesla Coil recordings of SSTC sparks. Recorded at 8000 frames per second and replayed at 15-30 frames per second. Notice the step leader, known from natural lightning strikes and the hot spots that might be forming from collapsing plasma channels. Join the discussion at High Voltage Forum about these high speed video recordings […]

TIG & Stick Welder, Migatronic Pilot 1800 Teardown

2 Comments / Teardown / /

A teardown of a Migatronic Pilot 1800, a combined TIG & stick welder. TIG is short for Tungsten Inert Gas and refers to the tip of the welding handle, which is made out of tungsten. A inert gas comes from the handle, to surround the tip and ensure no air is near the welding bath.

Where To Get “Free” TO-247 IGBTs and MOSFETs

Leave a Comment / Electronics / /

A look at a box of IGBTs and MOSFETs that I have salvaged from household electronics like microwave ovens, induction stoves, solar inverters, welding machines, car and battery charges and other common high power electronics with switching inverters. The TO-247 IGBTs can be used in a DRSSTC Tesla Coil using the free half- and full-bridge

Large Tesla Coil – Kaizer DRSSTC 3 – FULL POWER 19 kW!

Leave a Comment / Tesla Coils / /

We had a good session with the Large Tesla Coil. Trying out some different interrupters, targets and lighting around the coil, for filming. Darkness did however surprise us a bit and it was hard to adjust lighting and run the coil at once, so a bit noise filled videos. The future holds a collaboration with

Telemechanique Altivar 58, 10kW Motor Drive Teardown

2 Comments / Teardown / /

The ALTIVAR 58 (ATV58) family of adjustable frequency AC drive controllers is used for controlling three-phase asynchronous motors. This controller in from the range of: 1–75 hp (0.75–55 kW) constant torque (100 hp variable torque), 400/460 V, three-phase input. In this teardown, I am giving you an overview of how its built, non-destructively as the
