Adding a battery buffered realtime clock to the Beaglebone Black provides accurate time when no Internet is available. I used an Epson RX8025NB module, and connected it to I2C bus 1. Under Ubuntu 14.04 LTS a set of rtc drivers already exists, and enabling the clock was a simple command. The biggest work was to enable I2C bus 1… Continue reading »


Weihnachts-Geschenktipp: Ein Beaglebone Black ist das perfekte Geschenk in 2014. Endlich massentauglich, wurde beim Raspberry Pi Konkurenten in der dritten Version (Revision C) der interne Datenspeicher auf 4 GB hochgesetzt, eine 1GHz CPU macht Dampf, und es wird das vielseitige Debian Wheezy Linux als Betriebssystem ausgeliefert.

Drawn and rendered in Cinema 4D.


The C-Control system is a modular microcomputer system developed by Germany’s electronics giant CONRAD. A base CPU unit together with plug & play hardware extension modules provide a rapid development for various application scenarios. The displayed 4-port relais module allows to switch four loads of up to 2A and 25V from low-power 5V microchip pins.… Continue reading »
