In which we burn an arduino boot loader onto the ATMega, and then upload our own programs.
In which we add the crystal, finish wiring and insert the chip.
It was suggested to me that I should publish the actual circuit diagram of this project, together with a parts list. Here it is!
This is part two of a short series on how to build your own arduino-compatible board from scratch. You can find part one here: http://www.martyndavis.com/?p=105.
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!
Here’s how I diagnosed and fixed it…

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/
