VeroBoardUino – Last Part – Burning a Bootloader and Uploading Programs
In which we burn an arduino boot loader onto the ATMega, and then upload our own programs.

VeroBoardUino – How to Build an Arduino-Compatible Board for Very Little Money
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…

Ubuntu Unity – The Last Straw!
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.
Route Planner: Import Recorded Rides Easily
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!
Fixing Vertical Lines on a Scanner
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.
Here’s how I diagnosed and fixed it…

New Marengo GPS Route Planner – Out Now!
After too long a gestation period, the new version of the Marengo GPS Route Planner is out. This web-based application allows cyclists (amongst other outdoors types) to plot a route on a map and then upload it to their GPS unit to enable it to guide them.
New features include direct upload from the application to a Garmin device (Windows / Mac only I’m afraid, owing to Garmin’s requirements), a full “undo” system, auto-routing between points, elevation details and charting and more.
The new version is right where the old one used to be: www.marengo-ltd.com/map2/
