“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 …
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.
Using Raspberry Pi GPIO to read the contents of an old 5V CMOS ROM
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”
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”
