A week in which I’m probably going to walk the dog more than write. Monday 2020/06/15 Fixed a few bugs in some visualisation code I’ve been toying with on and off for several years. It can actually show the three projections of a volumetric data file now. Win. Now to re-work it to it’s possible …

Poor Mickey
Sometimes when you’re looking around for something to scan in your new-ish CT scanner the answer just lands in your lap. I’ve been doing #xraymyadvent again this year, but thought I’d test out the new scanner with an item more in keeping with the scanner’s intended use. Searching around the lab I found no obvious …
De-capping ICs for fun and profit, but mostly fun.
Some time back, a friend @codfishcatfish was building a GPS disciplined oscillator for radio measurements. Part of the circuit uses a MAX232 device to interface the low voltage digital signals to a PC serial port. He found his cheap (from eBay) MAX232s got very hot and failed in use. It was obvious the devices were …

Interesting patterns
Doing a bit more snooping around the radio spectrum with the RTLSDR (My HackRF should be here tomorrow!) I spotted these patterns in the transmitted signals from DAB stations. I’m fairly sure these are not just moiré patterns. I expect they probably tell you something about the multiplexing of the signals in the transmission.

Today’s item is barely there, gossamer wings and a steel staple.
