Emergency Pump Control with 555

The 8 microcomputer data operates with an 8-bit parallel output, while also accommodating serial input for D-A converters. Typically, data must be entered in two groups and processed as a whole. The requirements for data latching involve 16 straight...

This document outlines modifications made to the RIG RX-2 receiver, enabling remote control via a computer using an RS-232 serial interface. The modifications consist of two components: additional hardware and a new firmware program for the PIC16C84 microcontroller. In...

This is a motor controller circuit that controls the speed and direction of series-wound motors. This circuit employs silicon controlled rectifiers (SCR). The motor controller circuit is designed to manage both the speed and direction of series-wound motors, which are...

The circuit can control up to 6 kW of heating with moderate gain using a 25-amp triac (SC260D). Feedback is provided by a negative temperature coefficient (NTC) thermistor, which is positioned near the environment being temperature controlled. The temperature...

High-frequency voltage-controlled oscillators (VCOs) are challenging to construct. Maxim has developed an integrated 1.2 GHz oscillator, the MAX2754. The center frequency is adjustable via the TUNE input, while a linear modulation input enables frequency modulation. This integrated circuit (IC)...

This is a license to use the files to manufacture up to 12 boards. If additional boards are required, please make contact. It is important to note that the order must specify the intent to produce 12 or fewer...
