Simple Power Loss Detector with SMS Notification
Jun 28th
After having a few un-expected power outages this year, it got me thinking about how I could easily (and cheaply) be alerted (preferably via SMS) should one occur. With a laptop running Linux, a little bit of Python and some easily obtainable hardware and software, I come up with a simple method of doing just that. Read on for the code and set-up instructions.

This may be old news to some of you but I thought it was interesting enough to warrant a blog post.
The Podcast site Hacker Public Radio has a rather interesting episode about the current and future plans for the development of Python. Hope it’s useful to someone.

Handy Link: Programing an AVR with a Bus Pirate
Jan 7th
The guys over at HintShop have published a tutorial on using a bus pirate as an In-Circuit Programmer to flash firmware to an AVR Microcontroller using SPI.
As if that wasn’t cool enough, they also include instructions showing how multiple Mircocontrollers can be flashed by one Bus Pirate on the same board, in their tutorial! Is there anything this little gadget can’t do?
Handy link: Arduino Ethernet Bumper Pack
Jan 7th
Georg Kaindl, over at gkaindl.com has developed a collection of libraries for the Arduino environment which allows developers to make use of the DHCP, DNS and Bonjour (Apple Computers’ implementation of Zeroconf) protocols in their network-enabled Arduino projects. Documentation for each individual library (including installation instructions) can be found on Georg’s site.
If anyone is using these libraries in their own projects already, then feel free to share you experiences in the comments section. I’d love to hear about some of the cool stuff other people have made with them.

Handy Link: bpython
Dec 31st
bpython is a Python interpreter interface on steroids! It’s main features are:
- Syntax Highlighting
- A save function (to save code you’ve entered to a file)
- Auto-intending (we all know how important correct indenting is when you’re writing python scripts!)
- Auto-Completion which displays suggestions for any built-in functions, helping you to get the syntax for a statement spot-on without having to dig through reference manuals. The auto-completion feature also helps with import declarations, showing you a list of available modules as you type.
Installation in Ubuntu is as painless as typing sudo apt-get install bpython Other packages are available for Debian, Fedora and OpenSUSE as well. You can also obtain the source code from here and compile it yourself if need be.
If you need any help with using bpython, then check out the project’s webpage. Hope this is useful to someone.
