2024-09-20 Simple 1 Digit Counter, IR Beam Break
This short uses a CD4026, a 7 segment display, 9V battery, some resistors, an IR LED and a CdS photocell or phototransistor. Break the IR beam and the display advances to the next digit. https://www.facebook.com/reel/525596709839365?mibextid=9drbnH
2024-05-16 Delta-Sigma Modulator Using 555 IC And Current Source
This circuit is used for converting an analog signal into a digital pulse stream. Such things as class D audio amplifiers, servo amplifiers, A to D converters, or sending an analog signal across a fiber optic link. The Schematic and explanation here in this webpage. https://lrak.net/wiki/555_Delta-Sigma_Modulator.html The output signal is shown as audio modulated onto

2024-05-05 Tesla’s New Dojo AI Super-chip Will Be 40 Times More Powerful
A 5 min. YouTube video. Sam the Electric Viking said that the supercomputer is now in New York. There will be a new AI data center (being built) in Gigafactory Texas.
2024-04-20 RCWL-0516 Microwave Doppler Motion Sensor Module Schematic KO4BB
The modules use both the RCWL-9616 and the BISS-0001 but it seems the schematics are all labeled BISS-0001. The parts values are different. He gives some good information about them. They operate at 3.5 and 3.98 GHz – the ones I have were advertised at 5 GHz. Also he shows his own version that uses a
