Exercises in Geekdom

The Exercises in Geekdom mystery caches are a series of technical challenges aimed at cachers with a geeky nature at heart, whether you're a mathematician, computer scientist, or electronic engineer, you'll find something to tackle your grey matter.

There's puzzles involving programming (I code for a living), electronic games (I play games occasionally), some themed on my amateur radio background (I do have a licence), some themed on some of my life's experiences (childhood and adulthood).

If you get stuck, I'm happy to help you, but you'll need to tell me your workings.

And the most annoying... watch out for TedBot... that teddy must die.
