Something that I never knew until now. I’ll have to investigate further. Texas Instruments’ Gordon Teal Demonstrated Silicon transistor’s superiority at high temperature in 1954 https://www.facebook.com/reel/4383015895310864/?mibextid=9drbnH&s=yWDuG2&fs=e

Asianometry tells about the Regency TR-1 using a matched pair of 2N185 Texas Instruments germanium transistors. After 2:20 time
2026-03-30 Varactor, Varicap, Tuning diode
I think of a varactor as a dynamically varying capacitor: as the AC applied to it changes, the capacitance changes – so if this varactor is in a circuit with tuned circuits for input, output and idler, it can double or triple the input at the output. I needed to double the 121.5 MHz emergency

2025-11-26 How Many Books Could EUV Photolithography Put On A Chip??
The $200 million EUV photolithography machine from ASML takes about 18 seconds to expose a wafer. It can put an incredible amount of information on the chips. You’ve got to see this – I found that number of books difficult to believe!! It’s mind blowing!! 🤯🤯🤯 They said all the Harry Potter books, all the

2025-10-06 Schematic Of On-Off Touch Switch, Latching
This circuit uses four BJTs – 3 NPN and 1 PNP high current to drive the load. It has two touch pads, one for On and one for Off. I don’t see any information about the power supply voltage or load current. Some maximum voltage and current should be given for the circuit as shown.

2025-08-26 MOSFET Tester Is Not So Good
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

2025-08-10 Night Light Wastes Power Shunting Current From LEDs
This is the comment I left in Big Clive’s channel video. “I think this shunting current away from the LEDs is deceptive and fraudulent. They should be required to tell this in the instructions. In the US there are regulations governing vampire devices such as the AC adapters and their efficiency levels. Since they’re on
