Some recent photographs from the Regent’s Canal as it passes though the QMUL campus.

Too Hardcore

I caught this Rosemary Beetle early today with the intention of CT scanning it for #CTguess & #xraystuffinmylab on Twitter, also because I’m genuinely interested in these beetles.

Consulting the literature, it seemed that nitrogen asphixiation & several hours in a freezer should painlessly euthanise the beetle, leaving it in good condition for scanning.

This little fellow, survived in 100% nitrogen for more than four hours at -10 C. It was still crawling around when I fished its testube from the freezer to scan it.

You’ve got to respect tenacity like that, so I let the beetle go free again. Too hardcore to kill.

Weather

I’ve been playing around with a homebrew weather station again, I dusted off the code I’d had running on a spare Raspberry Pi and added a few features to it. It’s now logging temperature, humidity and air pressure. I plan to add some more external sensors as soon as the parts arrive from eBay.

The graphs below are live data (for as long as I keep the station running)



The code will be on github shortly.
