Hardware TeamCity Notifier

Nowadays usual PC is overloaded by different kind of notifications. Emails, instant messages, notifications from various applications disturb you continuously during working hours. Therefore it is very easy to miss an important message from the continuous integration system that yours commit has provoked some automated tests failure and it may have blocked work of other developers.

My solution was to make a hardware monitor, which should stay on some central place in the office, so that everyone can see the status of automated tests and whom to poke. As the device had to be quite cheap, and I didn't want to spend much time on making custom PCB, I decided to use Arduino platform.

Hardware:

• Arduino Nano Compatible 2$
• Mini ENC28J60 Webserver module Ethernet Shield board for Arduino Nano 6$
• Stepper Motor 28BYJ-48 + Drive Test Module Board ULN2003 5 Line 4 Phase 1.5$
• 74HC238 - 3 to 8 Line Decoder x 2 1$
• Reed switch 0.1$
• Resistor 1K x 16 0.1$
• Red Led 5mm x 8 1$
• Green Led 5mm x 8 1$
• Sanhe Enclosure 18-34 188x133x57 5$

Software:

• Arduino Software (IDE)
• EtherCard is a driver for the ENC28J60 chip
