Very excited to have a project featured in the MagPi this month, it’s a vintage Hitachi television I converted last year. It displays digital TV from another Raspberry Pi running a TV HAT, and uses the original rotary tuning dial to change channels.
As you can see hard copies are available in shops as well as the pdf version online. It’s a great issue all round and I’ve already been inspired to grab some arcade joysticks and buttons to try out some of the tutorials.
The article covers my experiences using the TV Hat with a converted TV from the 1970s – the original TV build Instructable write-up is here and the more recent TV Hat version is here. The simple Python script used to change the channels is available on GitHub.
There’s also a YouTube video of the unboxing and setup of the TV Hat…
…and one that gives a bit more information about how the Hitachi Pi TV was converted.
I’ve always been fascinated by televisions, as evidenced by the photo they included of me unboxing my first TV, aged around 10.
This old Dell monitor has been given a new life as a portable Scratch / Development station for Raspberry Pi projects – it has an integrated Pi 3 A+, fixed breadboard and Lego tape on either side for holding components in place.
I put it together mainly to make it easier to dip in & out of Scratch projects with the kids – with the Pi and breadboard attached to the monitor it takes seconds to set up, and with the Lego tape either side the kids can build structures to hold LEDs and other components in place while building code.
It’s also really useful for me when I’m developing code for projects, having everything in one place makes it harder (but not impossible!) to get sidetracked by trailing wires and loose connections.
My favourite part though is the Pibow Coupe Tangerine case (hotglued to the monitor) – I bought it because it looks great, but on assembly I noticed it has all of the GPIO pin numbers on it – this makes coding so much easier. I had originally planned to print & stick a GPIO guide on one side of the monitor but this saves all of the squinting and pin-counting.
Around the back the leads are all neatly cable-tied in place, with the Pi connected to the ol’ Dell with an HDMI > DVI adaptor. For power a single trailing extension lead connects it to the mains, with a plug-through USB adaptor fixed behind the monitor powering the screen and providing 2x 2.1a USB supplies for the Pi and accessories.
It was great fun to put together, and the monitor only cost £5 at a charity shop, PAT tested with a fully tiltable base. It’s especially useful in the winter months when the workshop is icy cold but we still want to get hands-on with the Raspberry Pi.
With winter staring to really bite this week it’s getting harder to be creative in the workshop, it was down to 3 degrees in there yesterday evening, as you can see!
As soon as the weather warms up a bit (or I sort out the insulation/heating) I’ll be back to making regular projects and videos, the T-card planning board in my office is full of ideas for 2019 and I can’t wait to get cracking.
If you have any project/video ideas or suggestions let us know on the contact form, and stay tuned for updates!
A quick hack to bring some retro gaming cheer to a USB power bank!
I’m working on a Retropie project at the moment, and want the end result to be as portable as possible, so that only an HDMI cable is needed to connect it to a TV. I needed a power source with enough stamina to run the Pi through a gaming session, but without interfering with the analogue style and portability.
The solution – embed an unused 2500 mah power bank into an old gaming cassette box!
This Guji power bank came free with my phone and was the perfect solution – it’s almost exactly the same size as a cassette box.
A few trims with the Dremel and the box was easily modified to snugly hold the power bank, leaving a good air gap around it.
It’s a nice little solution and only took a few minutes, but the power bank is now much more tactile and will hopefully fit nicely with the finished project.
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.
So excited to receive my Raspberry Pi TV HAT in the post this week! I’ve converted several old TVs using the Pi recently, like the Casio Pi and the Hitachi Pi but there’s always been something missing – an actual digital TV signal.
With the launch of the TV HAT so many possibilities have opened up, from adding a TV tuner to an OSMC Kodi build to streaming digital TV across the home network to other devices.
I’ll be releasing a “New Spec Review” video once I’ve fully got to grips with it (Mostly done, I’m half-watching a live stream of Carry on Cabby on the other monitor as I type), and I’ll also be testing it with my existing TV conversions – and maybe even making a nice retro case to hold the TV Server Pi in style. Stay tuned for updates!
It’s always a special occasion when we have a project in the MagPi, even more so in this case to be surrounded by so many other inspiring builds – there’s absolutely tons of inspiration to be had from this issue.
You can download the .pdf version for free but I’d recommend nipping to WH Smith or Sainsburys to get the super-tactile foil-cover hard copy!
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!
