UP/DOWN counter with memory using PIC16F88
Here is an up-down counter based on PIC16F88 and 7-segment display. The counter is using SMD components and features a RS-232 interface. This is a simple digital counter with a serial rs-232 and a 7 segment display, i started this project to count items on some shelfs, but it can be...

100MHZ Frequency Counter with PIC16F628A
This project shows how to build a very simple yet very useful tool that every DIY enthusiast should have in his lab: a 100MHz+ frequency counter. The schematic is fairly simple and straightforward and uses a PIC16F628A microcontroller for measuring frequency and a high speed...

The DigiRule – a digital ruler
Brad has designed a cool binary PCB ruler, The DigiRule: So I made the DigiRule! – The DigiRule is a 15cm (6″) ruler with which is marked in binary digits rather than decimal. It has a number of built in digital functions including: logic gates, flip flops, counters etc. The...
