Rotary Tuning with the Pi #TVHAT

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!

 

 

 

 

New Project: Retro-Fit a Google Home Mini

Bring some analogue style to your digital assistant by Retro-fitting it into an old cassette player or radio!

This simple and fun project only took an hour or so but brought a great-looking smart speaker to the wall of the workshop. I’ve covered the whole build from start to finish on YouTube…

… and the full build instructions are on Instructables and Hackster .

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.

New Project: Casio Pi CCTV Monitor

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…

…and on Hackster 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!
