The other day, I found a satellite navigation system in the street, complete with in-car recharger. Sheer merionesian curiosity forced me to switch it on and try it out. Nothing happened, because it was flat out of juice.
I did not have a suitable 12V power supply at work, but fortunately the charger ends in a standard mini-USB connector (like the one on a digital camera) and I was able to charge it from my computer.
Now, this thing belongs to somebody. I shouldn’t just keep it, even though it’s a Tom Tom One and eminently hackable (it’s running Linux underneath). So what am I going to do with it?
