Controlling my 1990s Technics tape deck from a 1990s PDA – Psion Series 3a remote control
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”
I recently bought a new turntable, the Audio-Technica AT-LP120XUSB. I wanted direct drive, decent quality (to match my ageing & damaged hearing!) and USB built in so I could hook up recording/streaming devices. I found an eBay listing for less than RRP and had a 20% off eBay voucher too so it was a no-brainer…Continue reading “Replacing white LED stylus target light on Audio-Technica AT-LP120X”
Creating a temperature monitoring dashboard in Grafana to display temps from sensors all around the house. Running on Raspberry Pis and using the venerable DS18B20 one-wire sensor.
Just dug this out of storage – some electronics I made in the late 80s/early 90s. Most of it is old/scrap components – only the 555 and the MC14526 counter/divider actually do anything – flashing the LEDs long the edge. I can remember making it at work during quiet times as a side project, IContinue reading “Flashing LEDs with a 555 timer – and not a lot else”
