DSO138 Oscilloscope Review, Test And Why You Should Not Buy It
Before you buy a DSO138 or DSO150 from ebay, amazon, wish or aliexpress, it is important to understand what you are getting. The specifications are very loosely written and what looks good on paper is useless in practical use. Here I test the DSO138 specified at 200 kHz, but in reality it is worthless above 20 kHz.

You have properly seen just as many gold refining videos on youtube as I have, dreamt of making a small fortune in homemade gold bars but always end up with a crushed dream when you realize just how much equipment, chemicals, protective gear and time that has to be invested in such a refinery.
Here I present you with a easy alternative that is exporting the scrap to a precious metal recovery company and get money straight into your bank account. No risks for your own health and safety from dangerous chemicals or machinery.

Discussion of Chinese 1800/2500W induction heaters: https://highvoltageforum.net/index.php?topic=530.0
Boxed version is powered by the "2200 Watt Server Power Supply For Induction Heating": https://www.youtube.com/watch?v=xRAlXCzsY3Q
This is a 1800 Watt Induction heater that I bought from ebay at 40 Euro, I avoided the cheapest seller for the simple reason that they all have bad reviews, so be sure to check that out before just buying the cheapest.
Pete who started the thread has a wide ranged knowledge of induction heaters. Check out Pete Stanaitis website: https://spaco.org/Blacksmithing/ZVSInductionHeater/ZVS1800Watt/1800-2500WattZVSInductionHeaterNotes.htm and his take on the 1800W IH: https://www.youtube.com/watch?v=S66Y-EZYhjo

Teardown of a AGFA ADC 5155 x-ray image scanner / digitizer. Also known as Computerized Radiography (CR) it fulfills the job of scanning a x-ray exposed image plate with a laser beam and extract each pixel illumination with a photo multiplier tube setup.
This particular unit has a very interesting computer that runs on VME framework developed for the Motorola 68000 series CPUs.

Over the years I have collected a great deal of salvaged #IGBT bricks from the different power #electronics I have taken apart. It have primarily kept 50+ Ampere rated bricks, single or half-bridge modules and 3 phase modules without builtin protection. It mostly comes from UPS, motor drives, welders or x-ray generators. #teardown
