The average hobbyist should not rely on this tester because of the deficiencies listed below. Instead he or she should buy a transistor tester that can analyze the device and tell what the pin out is and polarity, N-channel or P-channel. Also it can tell if the device is a MOSFET or a regular power

Gallium nitride power electronics will replace silicon and will make laptop power adapters smaller than a golf ball and will save major amounts of electricity. GaN devices will waste a lot less power, which will enable power electronics equipment to be made smaller and more efficient. Quote: “”GaN-based power electronics, on the other hand, could

The gate driver circuit shown in the screenshot uses BC547s, which are limited to less than 200 mA current. Instead, if the two transistors were BC337 or PN2222A which can easily handle over 500 mA, they could charge and discharge the gate faster, and thus reduce the dissipation in the MOSFET.
I received an email from Peter, who has planned on building a SSTC, solid state Tesla Coil. Peter gave me permission to post this email discussion to my blog. I have redacted some information for privacy reasons. “From:”Peter Bergmann” Date:Wed, Mar 23, 2016 at 5:31 PM Subject:It´s alive!! Dear Watson, since I just can´t get

I’ve built and blogged a ring oscillator that works good for making LEDs look like marching lights on a marquee. I think I could get 9 LEDs, the circuit and a 9V battery into an Altoids tin, and it would look cool. I’d have to paint over the ‘Curiously..’ whatever on the outside, though. The
