This file type includes high-resolution graphics and schematics when applicable. A solar-powered, daytime-only lamp without a battery for energy storage may seem to be a marginally useful device, but ...

For a nixie-ish kind of project with ZM1050's I need a power supply of around 150V, 20mA. The twist is that is that the polarity must be negative with respect to common ground. And of course, I wanted ...

Abstract: The paper presents different methods of using MC34063 and muA78S40 monolithic switching regulator subsystems to construct dual switching power supplies with step-down and step-up converters.

ABSTRACT: This paper presents a high-precision stabilized power supply boost circuit design. First, the MC34063ADG chip was selected to convert the voltage to +15 V to meet the input voltage ...

Update 21-August-2024: I learned that the IRQ line on the 65C22 wasn't connected, so I fixed that. See the section at the bottom for details, or just fab with the latest files and don't worry about it ...

MC34063 pinout diagram has been shown in the below image. On the left side the internal circuit of MC34063 is shown, and on the other side the pinout diagram is shown. Also, despite these features, it ...

Intel 8080 processor was released in April 1974, Motorola 6802 in 1976, and people in their late 40’s, 50’s or older may have experimented with those more than 40 years. People may still have those at ...

Project by Noel A. Rios. Complete schematics and full source code are available. Here is an 8051-series flash microcontroller programmer which can program the AT89C2051, AT89C4051, AT89C51, AT89C52, ...
