Parallel vs serial. What’s better?

Buying vinyl records at estate sales and flea markets is fun, but sometimes they are very dusty. So I bought this simple but clever device today: two acrylic discs + two rubber gaskets that can be put around the… https://t.co/41E4k8vCNc

As we’re celebrating 50 years of Apollo Moon landing, I’ve got a special present. This is a printout of one of programs Apollo computer was running, P63, “The lunar landing, braking phase”. And it was printed on IBM… https://t.co/sJ1ufgib3H

Picked up this clock at a flea market today. It may seem to be in a rough shape cosmetically, but all of that seems to be fixable. The clock light is not working, one inner knob is missing, and there seem to be a… https://t.co/ESzwG0roYw

Couldn’t pass by this double LP the other day: this is the original Star Wars soundtrack, released in 1977. A couple of interesting facts:

1. This is the only release by 20th Century Records, a child label of 20th… https://t.co/2B4cXZVP7O

Litronix 2290, introduced in 1975, is a recent addition to my small collection of calculators. It required no fixing other than cleaning of the battery contacts from a leaked battery. A cotton swab with a drop of… https://t.co/2QM5SUSY7A

Drove 40 minutes one way today in the hope to snatch this baby. Unfortunately, the asking price was too high for what you can expect at an estate sale. So given I already have one terminal, I decided to pass on this… https://t.co/EDjex2vQI8

Had a chance to see some old tech while traveling: here’s a few vintage terminals and typewriters onboard U.S.S. Missouri.

Finally found some time to repair and clean my Panasonic RX-F9 boombox. The problem was that both wires were ripped off the cassette motor (feels like someone did this intentionally) and one of the belts went off… https://t.co/NJRkh9UlPV

My linear turntable in action. Looks great with the warm caramel wood color of the TV credenza.

Bought today a soundtrack to the original “2001: Space Odyssey” film by Stanley Kubrick (1968). Mostly because of the vinyl album art, but it is interesting to listen as well!

Doing the first mechanical test to check if everything fits together, that cables are long enough, and that there’s enough gap between the shell and the CD disc.

Here’s another small AM-FM clock radio that I bought a few months ago at a flea market. It was manufactured in late 1970s, and while it’s not particularly rare or collectible, I think it still looks pretty cool. It… https://t.co/BIazER3PhZ

Today I was making a switch for the CD player I’m building. The metronome, which shell I’m using, had this multi-position level on the side to control the bell. I couldn’t reuse it as is, but I needed to do… https://t.co/OTvhVvNi9x

Cleaned up the clock today. This is a Panasonic RC-1091 clock radio, in a beautiful peach color. Works great, and has a sweep silent movement.

Also, while cleaning, made a few bonus pictures of it without the… https://t.co/e7GB9mE0NY

A guiding light of my linear turntable.

As we’ve got a heat wave here for several days now, I find it even more enjoyable to wait till the night comes down and temperatures become more bearable, and listen to some… https://t.co/E5x6fOHLhP

This is a replacement battery cover for Sony PS-F9 turntable. Here I followed the same process of 3D-printing, filing+sanding, priming and painting the part. Turntable has a hard-to match color: light pearl gray… https://t.co/ueKIJX0CiU

Today’s visit to a flea market resulted in me buying a Sony TA-AX390 amp/equalizer, and two shelf speakers, Bose 201 Series II, manufactured in 1984, in a perfect cosmetic condition. When displaying the speakers, the… https://t.co/NRrrxY163p

The final finishing of the CD player faceplate. I chose a glossy black paint, which makes all smallest surface imperfections and dust visible, and since I paint outdoors, it’s really challenging to avoid any dust… https://t.co/bXNcilZile

Of course it sounds better with a tube preamp! (Or so I’d like to think). But these two devices look organically next to each other, that’s for sure.
