Massage digital display circuit
The display circuit is utilized in a typical digital massager. At the heart of the control circuit is the microprocessor EM78156, which receives manual operation instructions. It triggers two transistors to supply voltage to the DC motor (A +, A-...
sap 1 simple as possible computer
An almost identical recreation of the SAP-1 Simple As Possible microprocessor, as published in "Digital Computer Electronics" by Albert Malvino and Jerald Brown. While the book is out of print, an eBook can be found relatively easily if one knows...
microprocessor Map processor to circuit diagram
How the processor produces 3 as the output. This question may be challenging to answer in simple terms. If so, a link to a book would be helpful.
The process by which a processor generates the output of the number 3...
Microprocessor RS-232 Reset
This circuit allows a remote microprocessor to be reset by a controlling host over a remote RS-232 or similar protocol serial line. With the use of a program loader on the remote host, a program may be downloaded and run....
Microprocessor power supply watchdog
The circuit monitors the input to the microprocessor's 5 V regulated supply for voltage drops and initiates a reset sequence before supply regulation is lost. In operation, the resistor-capacitor combination Rs and Cj forms a short time constant smoothing network...
HIP6302V Microprocessor CORE Voltage Regulator Multiphase Buck PWM Controller
The HIP6301V and HIP6302V control the microprocessor core voltage regulation by driving up to four synchronous-rectified buck channels in parallel. The multiphase buck converter architecture employs interleaved timing to increase ripple frequency and minimize input and output ripple currents. Reduced...
shutter
A microprocessor-controlled shutter control box for electrically driven shutters, such as the MELLES GRIOT 04 IES 003 and ILEX electric shutters. Older view camera lenses often feature shutters that may develop issues due to age or wear. While a clean,...
video turret
This document outlines the complete design for a microprocessor-controlled, environmentally sealed 8-inch video turret equipped with two cameras, offering remote or autofocus and zoom control. It features sun damage protection, 450-degree azimuth rotation, 9-speed scanning, point capability, multidrop network connection,...
Microprocessor-based home security system
A microprocessor-based home security system project. This advanced security system not only notifies the user but also alerts the police immediately. In the 8085 microprocessor-based home security system, control is exercised over a siren, telephone (via cradle and redial switches),...
