The mid-spring ice storm has taken its toll… my long-standing Butternut HF9V is no more.

Fortunately, I have some spare antennas (Buddipole, and some wire antenna if need be), but I shall replace this antenna. I was happy with the HF9V for almost 10 years.
[edit]
Looking at it today, it appears the 15m bit is broken, but that’s only a wire, so fixing that is trivial. The bend on the pole there is actually in the counterpoise kit, which is much cheaper to replace than the entire cost of the antenna, though still $400. Ugh.

Sunday night I was up late. I wasn’t sleeping and decided to log into GMail to do some clean-up. This is a regular task for me – I go in, empty the bin, delete old mails, sort the inbox into categories, etc. I’ve been doing this for years, usually from the same computer at home […]

I started this project as an attempt to teach myself about how computers worked. As such comments, useful links, or anything else related would be appreciated. Prior to this my experience in electronics was mostly microcontroller based. The computer is perpetually half done (it could be more it could be less, I only design the logic for the chunk I’m working on) but currently consists of about 300 transistors. I’m pretty sure that the computer follows ‘Harvard architecture’ (corrections welcome) as the RAM and ROM are strictly segregated. 4 bit is used loosely data width is 4 bits but instruction width is 8 bits as some instructions include 4 bit values. some stats: RAM: 16 nybbles (dictated by address register width) ROM: 16 bytes (dictated by program counter width) clock speed: more than one (the computer is currently not clocked as much of the sequential logic has yet to be built)
