Raspberry Pi

I was looking to add GPS to my Raspberry Pi (specifically the Clockwork uConsole) and found this USB GPS Receiver with 2m Extension Cable on the PiHut website.

The unit has a USB interface, a 2 meter long cable, and the GPS receiver itself is magnetic and so can attach to lots of different surfaces. Plus, since it was sold on the PiHut website I was quite confident that it would be easy to get working with the Raspberry Pi. As it happens, it was easy to get working, I just needed to install a couple of extra tools to make sure it was producing the correct data.

In this article we'll look at what happens when you plug in the GPS receiver, and then look at a couple of packages you can use to verify that the GPS receiver is working correctly. This assumes that you are running the latest version of Raspberry Pi OS.

I was doing some research into the Raspberry Pi a while ago and I happened to come across a neat little enclosure for the Raspberry Pi Compute Module 4 (CM4) called the uConsole.

The CM4 is essentially a normal Raspberry Pi 4, but it comes without the normal USB/HDMI interfaces that the Pi 4 comes with. This means that in order to use the CM4 you need to plug it into a separate PCB, which then provides the interfaces needed to attach monitors and peripherals.

This is where the ClockworkPi uConsole comes in. The uConsole (or micro console) is an enclosure for the CM4 that features a built in screen and keyboard, a track ball, small speakers, a battery pack, and an optional mobile network card.

After installing the RTL-SDR on my Clockwork uConsole (running a Raspberry Pi CM4) I was looking for something to try out the device to see what it could do. The GNU Radio Companion is still a bit baffling at the moment so I was searching for something with a lower barrier to entry.

One thing that caught my eye was a project on GitHub called dump1090. This is a "Mode S" decoder that uses the RTL-SDR to decode transponder information from Aircraft. Whilst the package is quite old now, it is still being minimally maintained. The dependencies are quite small and so it tends to compiles quite nicely without too many additional packages or issues, event on the limited hardware of the CM4.

I was scrolling through The Pi Hut website recently and my eye was drawn by a case for the Raspberry Pi Computer Module 4 (CM4) that looked like a modified Nintendo Gameboy. I had bought a CM4 for another project, but as that project wouldn't be delivered for a few months I was looking for something useful to do with the CM4 in the meantime.

The GPi Case 2 from Retroflag is a case that accepts the Raspberry Pi Compute Module 4 (CM4) and is used as an emulation station. Using the right software, it is possible to add files to the system that allow you to play games from a variety of different platforms. If you go for the WiFi CM4 you can also connect Bluetooth controllers to the unit and even use WiFi to transfer files.
