In retrocomputing circles, it’s often the case that the weirder and rarer the machine, the more likely it is to attract attention. And machines don’t get much weirder than the DEC Rainbow 100-B, sporting as it does both Z80 and 8088 microprocessors and usable as either a VT100 terminal or as a PC with either …

When working on projects with computation-intensive routines and (or) near real-time performance requirements, having a “lightning-fast” RAM is usually a good thing for developers. This is one of the reasons while STMicro included the Core Coupled Memory (CCM) RAM in a good number of its STM32 microcontroller series, and Dim Tass recently demonstrated how to use it, in a blog post …

A Binary Clock! I was recently looking at some binary clocks and I felt like Why not? I have everything to make one and I don’t have a clock in my room. So I decided to build one and here it is. Hope you Like it and maybe build your own. It’s a cool project …
I have toyed with the idea of building a clock for sometime and my sister had a big birthday coming up so I decided that this was a great opportunity to build a clock for her as a gift. My sister has a PhD in science and works as a science educator so I decided …
Some years ago, I came across Mignon and Meggy Jr RGB, and was intrigued enough to want to make something similar, but with a wider screen, more possibilities for experiment and play, and with few parts. I called it Armadino, after seeing an armadillo logo on the spine of a children story book and mixing it with the word …

Project and Instructable write-up done by Ian Lacy on behalf of the MIT Edgerton Center. In this project, I’ll show you how to build an Apollo 11 clock. The clock has each hour associated with a leg of the mission, and plays an associated audio clip at each hour. Every third hour, it also has a …
We went all ‘cord-cutter’ and ditched our Cable box and realized something was now missing in our family room…the oh so familiar LCD clock that was always present. I decided to get to work on a replacement and had some fun with it. If you’re like me you’ve ordered an Arduino kit here and there when the …

Today we are going to make a real time clock Arduino shield. Doing so will give you a simple way of adding … real time capability to your projects such as time, date, alarms and so on. We will use the inexpensive Maxim DS1307 real-time clock IC. First of all, we need create our circuit …
Introduction Time for another instalment in my highly-irregular series of irregular clock projects. In this we have “Clock Four” – a scrolling text clock. After examining some Freetronics Dot Matrix Displays in the stock, it occurred to me that it would be neat to display the time as it was spoken (or close to it) …

Miniature Atomic Clock (MAC – SA5X) Rubidium Oscillator, re-designed for improved stability and new features. The MAC-SA5X is designed for applications that require long-term atomic oscillator stability, but are constrained by size and low power requirements. Versatile Microchip’s next-generation MAC-SA5X miniaturized rubidium atomic clock produces a stable time and frequency reference that maintains a high degree …
