6 digit 7-segment counter "Angus 6"

February 24th 2016

 
Overview
 
This is a counter board based on the 4026 logic IC (counter / 7-segment driver)
 
A counter board featuring 6 20,3mm high 7-segment LED displays, and driven by 6 4026 logic ICs.
 
Details
 
There are six ICs in total driving the 6 20.3mm 7-segment LEDs, allowing for counts of 0 to 999,999. Daisy chain them together for billions of counts!
 
With a 5v supply, this board can count at up to 2.5MHz, with a higher supply voltage (larger resistors required) it is capable of 8MHz.
 
Usage Suggestions
 
Need to count something? an input? or an output? Then this board is for you!
 
Use the square wave output from a DS1307 realtime clock (or similar) to make a clock that only shows seconds elapsed - 1 million seconds is just over 11 days. Connect two boards together and count for 11 million days (over 31000 years!). Connect three for 31 billion years :)
 
Check out the schematic below to build a simple 1Hz driver add-on board.
 
Why not drive it from a 555, for example, using the 555 astable oscillator kit.
