Nixie tubes are, of course, an elegant display method from a more civilized age, but actually powering and controlling them can be a challenge. This can mean a great project and learning opportunity, but if you’d rather just skip ahead to programming these amazing lights, then Marcin Saj’s IN-2 binary Nixie clock is definitely…
We recently obtained a clock that flew on a Soyuz space mission.1 The clock, manufactured in 1984, contains over 100 integrated circuits on ten circuit boards. Why is the clock so complicated? In this blog post, I examine the clock’s circuitry and explain why so many chips were needed. The clock also provides a…
On the hardware of the controller board LED Matrix, by taking advantage of the reconfigurability of the onboard FPGA, we can build a bivalent tool that is extremely useful to have on our work bench. If you’re looking for a tool for measuring frequency that is not the classic multimeter and, in the various…
Raspberry Pi enthusiasts searching for a quick project to keep them busy this weekend may be interested in the new Raspberry Pi Zero clock and temperature gauge which has been created by Hackster.io member Jeremiah Mattison. He has Kindly published everything you need including full instructions and code overall in the Hackster.io website allowing you to recreate…
Interesting project to take inspiration by, a word clock featuring Arduino to control the “minute words”! As I was making a word clock, based on another instructable ( http://www.instructables.com/id/My-Arduino-WordClock/ ), me and my sister were wondering whether a round design would be cool too. While searching the internet, I could not find a round word…
Let’s see how to use this shield along with Raspberry Pi, by means of a dedicated library. In the last installment we gave readers description of a new RTCC shield, based on the MCP79410 integrated circuit, by Microchip just after having presented the sketch for Arduino; now, as anticipated in the first installment,…
Let’s use a new Real Time Clock by Microchip, by making it available on a shield for two prototyping boards. First Installment. Many applications require an hourly information, that is locally obtained by means of circuits that are named RTCs (Real Time Clock) or RTCCs (Real Time Clock Calendar); among them are clock…
Great introduction video to the Micro Word Clock by Daniel Roja: A tiny replica of the famous Word Clock, using only an ATmega microcontroller, a DS1307 Real Time Clock and a few passive components to display the time on an 8×8 LED matrix. The letters have been printed onto a transparent sheet and glued over the…
[youtube id=”5H85RDA5HEw” width=”620″ height=”360″] Today we present a mod of Dotklok, the product that we presented few months ago , with new features such as reading ambient temperature and controlling display brightness based on the ambient light. The whole thing can be controlled remotely via a standard TV remote control. Open firmware and hardware have…
[youtube id=”5H85RDA5HEw” width=”620″ height=”360″] Andrew O’Malley, an amazingly creative maker, created this fanstastic Open Source Arduino-based clock that can display the time in many different ways: if not enough, one can also add his own personal animation. Andrew’s idea Compared to other clocks based on Arduino, this one has two distinctive features: a single…
