In which we burn an arduino boot loader onto the ATMega, and then upload our own programs.

It was suggested to me that I should publish the actual circuit diagram of this project, together with a parts list. Here it is!

Note: this was going to be one post but it’s ballooned into a huge thing so this is one of several which will be posted over the next few days. Stay tuned!
So you’ve got a nice Arduino board for experimentation and you’ve built a circuit on a breadboard which you’d like to make permanent.
It’s expensive (and overkill) to use a new arduino each time you build a new circuit you want to keep. Here’s how you can easily build an arduino-compatible board, from complete scratch, for a few pounds/dollars/euros so you can keep your real arduino for experimenting with…

The whole point about Linux, surely, is that it gives freedom back to the user.
So what’s with Ubuntu? I got used to the buttons suddenly going on the other side of the window bar in 10.04, but this whole Unity thing now has just pushed me a bit too far.
If you’ve got a Garmin Edge 605 or 705 and you’ve just gone for a ride, if you remembered to press “start” on your GPS at the beginning, your Edge will have recorded your route. You can find the files in the Garmin/History folder on your device when you connect it to your computer. Annoyingly, though, they’re saved in TCX format, which is a Garmin specific format. These files were difficult to import into the route planner: you needed to go through all kinds of hoops to convert it to a GPX of the right type so you could import it and see your ride on your computer. Now, however, with the latest release of the Route Planner, you can import TCX files natively. Just select File / Import from the menu!
My Epson Perfection 1640SU scanner recently started behaving slightly less than perfectly… I had a pronounced light vertical line appearing down the length of each scanned image.
Really annoying.
Here’s how I diagnosed and fixed it…
