So the Raspberry Pi has been around for 10 years… everyone’s favourite credit-card-sized computer does just about everything
I read an online post about creating an “MC400 emulator”. That got me thinking about the ROM, and the 28F010 flash chips that realise it…
A summary of all the things that are right with my 1991 Psion MC400 laptop, “online” via an attached Raspberry Pi 3B+ and wifi…
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 😦
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!
Controlling my 1990s Technics tape deck from a 1990s PDA – Psion Series 3a remote control via NodeMCU
Using Raspberry Pi GPIO to read the contents of an old 5V CMOS ROM
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”
