Slow Progress

Posted 2011.06.19 20.36 in Computers/Internet/Technology

I’ve been working now and then on my Next Project. It’s slow going but there is progress happening.

This weekend I added a power supply (boring) and a radiation sensor (interesting). The radiation sensor is basically a geiger-muller tube detector. Instead of making audible tick sounds, I modified it to flash a blue LED whenevever it detects ionizing radiation. The counts are tabulated by the MCP’s microcontroller and available as a cumulative counts per day or current counts per minute.

What else can it do?

  • It is a remote display and remote control for my Thermostat.
  • It controls the lights in my aquariums.
  • It monitors the temperature in my aquariums.
  • It controls my Game of Life display.
  • It monitors and displays outdoor weather conditions.
  • It notifies me of activity on my home file server.
  • And now it monitors ionizing radiation.
  • It allows me access to all of this information and all of these controls both in-person and via network.

So I can monitor and control any of this stuff from my iPhone, iPad, at home or at the office, or anywhere.

The main board is an Arduino Mega. It’s using an Ethernet shield and an XBee shield. The radiation sensor is next to the Arduino. The display is a ks0108 glcd. More geeky goodness will be coming next week.
