In which I investigate whether I can connect an Arduino Ethernet shield to my Veroboarduino. Not as easy as I first thought it would be!

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.
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.
Really annoying.
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/
