Bidirectional Speed Control for DC Motors
This is a very simple bidirectional speed control of a small DC brushed motor. The project is built using power OPAMP TCA0372 which can drive a load up to 1A. Connecting a small DC motor and trimmer pot will control the motor forward/reverse operation along with speed control. A...

Juergen’s 100 MHz 65F02 Microprocessor is designed to work as an Accelerator for 6502 And 65C02 Computers
The 8-bit, 2 MHz 6502 microprocessor of MOS Technology, now CSG, had gained widespread use on classic computers of the late 1970s and early 1990s, like the Apple II plus, games consoles, and chess computers, though the games consoles and chess computers were mostly CMOS 65C02-based. The...
