This simple counter is built based on PIC16F84A and SAB6456 IC. The SAB6456 is a prescaler for UHF/VHF tuners. It can be switched to divide-by-64 or divide-by-256 by the mode-control (MC) pin. The circuit has an input frequency range of 70 MHz to 1 GHz, has high input sensitivity and good harmonic suppression.

With RS232 quickly being replaced by USB, the nightmare of incorrectly wired appliances and forgotten baud rates will be a thing of the past. Unfortunately RS232 will still be with us for a long time to come and as it becomes used less frequently the exact parity and baud rates for devices can easily be [...]
The purpose of this project is to build a device that can keeps track of the score and which team is serving. Mounted on the edge of the ping-pong table, the device speaks to you – scores and service are announced verbally. They are also displayed on the LCD.
The ping-pong score keeper is built using [...]
If you want to build simple function generator then this circuit is for you. This function generator is built based on IC XR-2206. It can be used to generate Square, TTL, Sine and Triangle waveforms. The frequency range is from 1Hz to 1Mhz and adjustable via VR3. User can change output voltage using VR2.
