I am really excited about space probe Dawn's arrival at Ceres on March 6th! Ceres is a dwarf planet in the asteroid belt between Mars and Jupiter. Like many other people I've been eagerly anticipating this part of the Dawn mission for a few years. After a long trip via Vesta, NASA will get higher resolution images of the surface of Ceres from Dawn in the coming weeks.

"Ceres is almost a complete mystery to us," said Christopher Russell, principal investigator for the Dawn mission, based at the University of California, Los Angeles. "Ceres, unlike Vesta, has no meteorites linked to it to help reveal its secrets. All we can predict with confidence is that we will be surprised." via NASA

We live in an age where there are new and exciting things to learn about every day, but this event really stands out for me. What wonders await us on this new world?

Here is a bit of code I wrote recently for the Gameboy Advance platform. It lets you use the device's buttons to toggle GPIO pins.

Recently I ressurrected LooperAdvance, a bit of 10 year old code for making music with a Gameboy Advance. I am hacking in synchronisation so that I can sync up the loops with Pure Data running on a Raspberry Pi.

The Gameboy Advance has a pretty robust little 4-bit GPIO rated at 3.3v that could be neat for controlling some projects now that you can get them quite cheaply second hand. There are also wireless adapters available that will instantly give you 4 bits of output by remote control.
