An elegant, stacking, Real Time Clock for Raspberry Pi

If you want to build a good Real Time Clock for your Raspberry here's the tutorial you were looking for! This is a revised and simplified version for Instructables made out of this article at my personal blog. Difference is mainly in the structure and my article is a bit more verbose. Why another "annoying" how to on building a Real Time Clock for the RPi? Because almost everywhere you find instructions tel ...

A Raspberry Pi Controlled Two Faced Clock

This instructable shows how to use a 'Simple but Strong Plastic Box', (http://www.instructables.com/id/A-Simple-but-Strong-Plastic-Box/) from my previous Instructable, to make a Two Faced Clock which uses a Raspberry Pi to control two stepper motors. I'll not explain how to make the box itself, but will show how to measure, mark and make the holes for the stepper motor drive shaft. At the end will be links ...

Analog Gauges Using I²C on the Raspberry Pi

I’ve been intending to try driving Switec X25.168 motors using the MCP23008 I²C I/O port expander chip from an Arduino, but it occurs to me that it might be more interesting to try this on a Rasberry Pi. If it works, it will demonstrate a simple and very inexpensive method for driving analog gauges from the Raspberry Pi without the need for high-current drivers. The MCP23008 provides 8 I/O lines controlled ...

Adding a Real Clock Time to your Raspberry PI

The Raspberry Pi doesn’t have  a little coin-battery-powered 'Real Time Clock'  (RTC) module, which keeps time even when the power is off, or the battery removed. To keep costs low and the size small, an RTC is not included with the Raspberry Pi. If  your Raspberry Pi is connected to the Internet via Ethernet or WiFi, the time/date will be automatically updated from the global ntp (nework time protocol) ser ...

Prototype and configure your own Real Time Clock module for the Raspberry Pi ( Open Source Hardware and Software Configuration)

To keep the price of the raspberry pi down the developers left out some of the essentials one of those is the real time clock. At the moment the raspberry pi gets it time over the Ethernet from updating the time automatically from the global ntp (nework time protocol) server, but this means that when the Ethernet is unplugged and the Raspberry Pi Powered Down the raspberry pi has no way to keep the time or ...

A combined MSF/DCF atomic clock receiver

For this to work you must obviously live in an area that can receive both signals. My circuit is based on two modules taken from two radio clocks bought at Lidl's supermarket. Originally both were for the DCF clock but by substituting the original 77.5kHz crystal with a 60kHz crystal, one of the modules was converted to MSF. Notice that both antennas are lined up in my photograph. This is because Anthorn an ...

Raspberry Pi water alarm system

Instructions for employing a Raspberry PI as a water alarm system Version 1.0, published in Jan 2015 The Raspberry Pi reads the status of one or two water sensor device(s) on one or two of its GPIO pins. When water is detected the Raspberry Pi emails out an alert to a recipient group and calls a phone number list via VoIP playing a stored wave file with a spoken alert phrase. If the running system hangs up ...
