A summary of all the things that are right with my 1991 Psion MC400 laptop, “online” via an attached Raspberry Pi 3B+ and wifi…
As of July 2021 Linux has been around for 30 years. For almost all of that time I’ve been installing Linux on just about anything I possibly can….
Getting the 1990s era Psion MC400 laptop online via an attached Raspberry Pi and some custom shortened Psion serial-USB cables… Tweets, Emails, BBC News & screenshots! All in glorious monochrome and at 19200 baud 🙂
Some patterns…. the beauty in repetitive patterns, in nature and in art.
NASA has ambitions to build a comms infrastructure on the moon using 4G LTE technology…
Connecting my retro-laptop to the internet via 2 x RS232 serial connections to a Raspberry Pi… and defeated (for now) by lack of hardware flow-control signals 😦
Was 1981 pop music’s greatest ever year? There’s no doubt for me – it absolutely was! Débuts from several of the decade’s biggest names, Eurovision Winners and a novelty No.1, 1981 had it all.
About my Love of bags – this one a dot-com era superstar from 2000/2001. Internet enabled fashion? Oh yes! SKIM.COM a y2k style bubble ready to burst 🙂
My homage to Doug Rocket’s art installation at Place “MY LAPTOPS 1991-2005”. It’s well Mexico.
Some older GPS receivers can’t compute dates properly thanks to the original GPS system employing an epoch with 10-bit week number… a new epoch starts every 1024 weeks!
Why vinyl is more than the sum of its parts. “Record Store Day” 2021 and queuing for 2 hours to buy a black plastic disc. Independent record shops and teenage memories…
Connecting 30-year old computers to the internet in 2021… for the LOLs. Revisiting RS232, null-modems and the like, all at 19200 baud.

Controlling my 1990s Technics tape deck from a 1990s PDA – Psion Series 3a remote control via NodeMCU
Retro computing. Getting 1990s era computers connected to modern stuff….
Back in the early 1990s I was a serious Psion-a-holic. If there was such a thing as “Psionaholics Anonymous” I would’ve been there. My first machine was the ground-breaking Series 3 and I was instantly hooked. After that I owned a Series 3a, Siena, Series 5 and later a Revo. These machines had soul. IContinue reading “MCMF – MF4 dialling for the Psion MC400”
“Electronics & Music Maker” (E&MM) was a magazine aimed at home/hobby music makers that started in the early 1980s and was produced as an offshoot of the mighty Maplin electronic component distribution empire. The idea was that it would promote more sales and engagement with Maplin’s component business through projects & DIY features based aroundContinue reading ““Electronics & Music Maker” – archiving a demo cassette from 1982″
Reviving some 1990s era tech …
I was saddened to learn of the passing of Lou Ottens, a Dutch Engineer credited with inventing the humble cassette tape format whilst working at Philips in the 1960s. Crucially Philips had the foresight to licence the format and it quickly became the de-facto standard for consumer audio recording. It made me reflect on justContinue reading “A Life-long Love Affair with “Compact Cassette””
Bought an old Hi-Fi from eBay – seller listed it as “used” (meaning it works OK but might have some cosmetic damage). Turns out it was faulty. D’oh.

Defeating SCMS copy-control restrictions in digital minidisc-to-minidisc copies using the infamous Elektor copybit killer from 1998
Creating a remote control for a 1990s tape-deck using raspberry pi, python, node-red and some relays. Features minimal hardware hacking of the tape deck itself… 😉
I discovered this tiny oscilloscope kit the other week. It’s a DSO138 by JYE Tech – £30 from Amazon(UK) or less than £20 if you can wait for delivery from China 🙂It took me less than 2 hours to build and worked first time! I’ve still got some soldering skills lol. It comes in twoContinue reading “Tiny Oscilloscope kit based on STM32F103 ARM microcontroller”

Hi, and welcome to Zed Starr’s compendium of techno-bizzle. Sometimes a bit retro, or getting retro stuff to do things in “modern life”; featuring Raspberry Pi, Linux, GNSS, analogue audio/Hi-Fi, Psion computers and with an overall electronics flavour. And no, I’m not sure what exactly “techno-bizzle” is either… Enjoy!
