This iconic digital clock from the 1970s now has a new life stylishly displaying YouTube statistics. It’s powered by a Raspberry Pi Zero and harnesses a simple Python script to retrieve Subscriber and View numbers for the Old Tech. New Spec. channel from the YouTube Data API, displaying the results on a Pimoroni Inky pHAT display.
The clock’s original alarm on/off switch now toggles the e-ink display between Views and Subscribers, and an inbuilt LED glows up the translucent red plastic around the display as it updates.
It’s a fun & practical addition to my office, sitting quietly on my desk speaker, and seeing the stats slowly increase helps keep me motivated to make more projects and videos. It also won First Prize in the recent Instructables Internet of Things Contest!
I bought this clock a year or two back, bundled with an old robot toy, and it was in daily use until it went pop recently – when it joined the ranks of broken Old Tech in the workshop awaiting conversion. The build was straightforward and involved a lot of precise measuring, as well as my favourite Raspberry Pi companion, Lego bricks!
I’m really pleased with the result and it’s a lovely looking little thing – nice coverage on the Hackster Blog too!
The PiNG Video Doorbell is powered by a Raspberry Pi and is retro-stylishly cased in a 1986 Intercom and an old Sony cassette player.
When the doorbell button is pressed the Pi makes a high-quality video call using Google Duo, which can be answered on a phone, tablet or computer, letting you see and speak to callers when you’re away from home (or at home but trapped under a cat). It works over WiFi and cellular, so you can even answer the door when you’re out pounding the streets.
It also sounds a standard wireless door chime inside the house as a fail-safe, in case the call can’t be taken.
The doorbell unit is fitted outside the house, with a companion base unit inside, connected with 6-core alarm cable. The base unit houses a Pi 3B+ and is housed in a stripped-out cassette player.
It works amazingly well and the Google Duo sound and video is smooth – I took a call from a delivery person while out walking yesterday lunchtime which was very exciting!
I started this project in early March and finished it at the Easter weekend, and it’s been an absolute barrel of fun, I’d highly recommend playing around with Google Duo on a Raspberry Pi! If you have a Pi and some bits lying around you can probably make something similar in a couple of hours.

The Raspberry Pi TV HAT arrived a week or so ago and we’ve had great fun setting it up and using it. It does a great job of streaming a digital TV signal around the house, and I use it daily.
For me though the critical thing was being able to easily stream TV to other Raspberry Pis – I have several converted vintage TVs (Like the Hitachi Pi and Casio Pi) and really wanted them to be able to display actual live TV broadcasts.
With a bit of Python I now have the 1982 TV Experience live on the Hitachi Pi! It uses a script to step through four separate VLC playlists (to match the four channels we had in 1982) using the TV’s original rotary tuning dial. The script is on GitHub and is really simple – you could also just use a push button.
I’ve covered my experiences (with some assistance from the cats) in the “New Spec Review” video below, and the write-up is live on Hackster and Instructables.
The next project is definitely going to be finding and adapting a nice vintage case for the TV server Pi – stay tuned for updates!
This is a great way to make practical use of an old or broken cassette player, securely wall-mounting your Google Home Mini into the bargain.
I had the Home Mini kicking around the workshop in its box for almost a year before getting round to building this, and now I use it literally every day. It’s especially handy when you’re up to your elbows in solder and components and need to change the music or podcast.
This is a sweet little Casio portable TV that I’ve converted into a handy CCTV monitor using a Raspberry Pi Zero W. It uses all of the original TV circuitry and the Pi is tucked away inside the battery cover. It’s ideal for keeping an eye on the cats or looking out for the postman!
It plays a video stream from a Pi Zero CCTV camera running MotionEye OS, but can equally play local files or any video stream using Omxplayer – it’s a great way to cheaply add a screen to a Pi project, as these old TVs can be powered from the same USB as the Pi and cost as little as £2 second hand.
The project is pretty straightforward and is fully documented on Instructables at…
The build is also covered step by step on YouTube:
It’s the first project I’ve covered from start to finish with a video and it was a ton of fun. The video’s a bit longer than I would have liked but is split into chapters and these are linked from each section of the build on Instructables and Hackster at the links above. Now that I have the video template working and the recording equipment (mostly) behaving itself I hope to publish videos more regularly!
The YouTube channel is finally ready for business, Subscribe now for your regular fix of #Retro meets @Raspberry_Pi!
I’m hoping to publish a regular monthly project video with Retro-Spectives and New Spec Reviews in between. The monthly video will cover all the stages of a project in detail so you’ll be able to follow along and give some of your Old Tech a New Spec!
