144 7-Segment Displays Combine To Form A Mighty Clock

What do you do with 144 7-segment displays? If you’re [Frugha] you put them all together to create an epic clock. Each display has 8 individual LEDs — 7 segments, and a decimal point. Put that all together, and you’ve got 1152 individual LEDs to control. This presented a problem, …read more

MNIST Clock Uses Famous Training Database

When training neural networks to recognise things, what you need is a big pile of training data. You then need a subsequent pile of testing data to verify that the network is working as you’d expect. In the field of handwriting recognition, the MNIST database is commonly used to train …read more

Foxie Clock Works In Two Ways

Nixie tubes are a hacker favorite for their warm glow and elegant, mid-century numerals. They’re also a pain to drive, demand high voltages, and aren’t exactly cheap and easy to come by. Never mind, for there are other ways to go – as [Alex Fox] demonstrates with the Foxie Clock. …read more

Nixie Clock Claims to be Simplest Design

[Engineer2you] built a nixie tube clock and claims it is the simplest design. We felt like that was a challenge. In this design, the tubes are set up as a matrix with optoisolators on each row and column. With 60 segments, the matrix allows you to control it all with …read more

74-Series Clock Gets A MEMS Heart

[Erik van Zijst] has had a long career as a programmer, but lacked an understanding of what was happening at a bare metal level. After building a few logic gates out of transistors to get a feel for electronics, he set out to build a working clock using 74-series logic. …read more
