I'm a PhD student from Adelaide, Australia (yes, we have a hackerspace,
though a small one) currently staying in Bath to work on TOPCAT, a
ionospheric observation payload to go on the UKube-1 cubesat.
I'm also heavily involved with Project Horus, a high-altitude ballooning
group that is now up to 15 launches - recovering every payload we send up.
I'm planning to visit London next weekend (13th/14th) and would very
much like to visit the hackerspace, and perhaps give a short talk on
Project Horus or TOPCAT - would anyone be interested?
