“Clocks are a problem for me, I keep designing them but I never seem to finish building my designs. I’m not really sure why. Maybe it’s because I limit myself to using only TTL logic, or that my …
“This project was inspired by my dad’s university digital systems project from the late 1970’s. I found the writeup and schematic and decided to try and re-create it. You can see the results of the breadboard reproduction and …
“Currently there is a lot of interest in bringing vintage nixie tubes to life. Lot’s of nixie tube clock kits are available on the market. There appeared to be even a lively trade on old stock of russian nixie …
“A TTL/CMOS based clock that displays the time along a 60 LED bargraph. I like clocks. I like LEDs. I like mucking around with circuits. I want to make a clock that displays the time along an LED bargraph …
“Hi there! I am Shivansh, a student at IIIT-Hyderabad. I am here with my first instructable which is a game inspired from Google Chrome’s Dinosaur Jump game. The game is simple: Jump across incoming obstacles in order to …
“This project is an RGB Electronic Die that generates the codes from 1 to 6 through 7 RGB LEDs as outputs for showing the mentioned numbers while the inputs are the codes generated by a 7490 counter fixed to count …

“This project is the last project of the trilogy of binary counters before beginning to work with my Binary Clock. They are Green Binary Counter, 2-Digit Binary Counter, 4-Digit Yellow Binary Counter, this project. In the present project, I’ll …
“I have built a binary counter without using decoder. The diodes do the magic while the materials are: 1-7490 counter, 4-1N914 diodes, 1-555 timer, 2-4.7Kohm, 1-100uF capacitor, and 4-5mm LED’s.”
