Exploring a discarded cable box I found at the landfill. When I'm done, I'll give to a friend who recycles electronics.
This is an old Z80 based computer that I built many years ago when I was in high school. It's somewhat battered and in need of repairs - but since it's been floating around for 20+ years, I think it's doing ok!
It was designed by a small electronics company here in Melbourne, Australia called Talking Electronics
I was a big Heathkit fan. Other kits included GR-680 Color TV (tube type), GR2502 Color TV, H-89 Computer, IO-103 O'scope, and AR-15 Stereo Receiver (which I still have and use).
A bulk pack of 2500(50 values X 50pcs) 1% 1/4W resistors. They were from Hong Kong, Other than getting 2 sets of 33k and possibly missing another value in it's place. Their quality is good and they were cheap.

Один из наиболее массовых советских процессоров. Оказалось, что вопреки распространенному убеждению, он не является послойной копией Intel 8080/8080A (некоторые блоки похожи, но разводка и расположение контактных площадок существенно отличается). Самые тонкие линии — 6µm.

Soldered up the prototype board for the picaxe 08m chips I bought. Managed to get the axepad program to connect and upload program to the picaxe chip, though no visible output yet.

All soldering and wiring done.
Definitely not the best soldering I've ever done. Seems I need the practice…
Less than the smart phone. The PC it was purchased in November 2015. Because it was half price at the time sale of Amazon, impulse buying without any purpose. When you try to use to try while you are out to repair the main PC, Web, of course, to the movie is seen, in use as a sub-PC because Nikon NX-D was also moving.
The HD44780 controller is a very common little chip that acts as the brains behind little character-based displays. These displays are every, every, everywhere - the gas station down the street from my house has them in the gas pumps and the cash registers, our new printer/scanner uses one, and I'd bet my eyeteeth that the little glowy displays in modern pay phones are driven by a very similar chip. Srsly. If you spend some time out and about in a well-settled part of any developed nation these days, you're bound to encounter several of them. There may well be some in your home, especially if you're a gadget freak.
I think the HD44780 is mid-eighties tech. They're not as flexible and fancy as graphic LCD controllers, but most applications don't need much. The HD44780 and its clones usually come with the English alphabet built in, as well as punctuation, numbers, and the Japanese katakana syllabary. There are also a few umlauted letters, Greek letters, and symbols - even an ñ! Scroll down a bit on this page to see the whole gang.
Code for using these displays is very easy to find on microcontroller hobbyist sites, but I wrote my own - as a software guy, I consider that the fun part. This picture shows a display I recently bought on eBay for about $11. It has an odd greenish-yellow backlight, which accounts for the lemon-lime background color. The display area is about 1x3 inches. I've just managed to get my interface code for it working - I've been using these for years, but with a different fambly of microcontrollers, and have just now gotten around to writing the code for the AVR MCUs. Now that I have it going, what can I not achieve?
The text extends a greeting to the almost-absurdly-beloved Japanese cartoon character Totoro, whose name is one of the few katakana words I know. (I highly recommend the movie My Neighbor Totoro. If you haven't seen it, check it out - it's beautiful, beautiful work and one of the sweetest films I've ever seen.)
カワイイ!

Sadly revision one of the case has a few small issues: the side panels aren't actually long enough to interlock, so there are gaps in the corner, and the tabs at the top of the front and back panels overlapped and got cut in, so there are no tabs there. Everything else works nicely, though!
