We all know the Raspberry Pi Zero W is small, but Smeef’s Pi-Tac project is perhaps the best illustration of that fact that I have ever seen. The setup stuffs not only a Pi Zero W into a Tic Tac box, but also all of the supporting electronics needed to make it into a portable device. It could be …
The ANAVI Info uHAT is a mini OLED display complete with buttons and slots for sensors specifically designed for the Raspberry Pi. Providing a low-cost open source Raspberry Pi add-on board with a resolution of of 128 x 64 individual white OLED pixels. ANAVI Info uHAT works with any Raspberry Pi single board computer (SBC) with …
Personal head-up displays are a technology whose time ought by now to have come, but which notwithstanding attempts such as the Google Glass, have steadfastly refused to catch on. There’s an intriguing possibility in [Basel Saleh]’s CaptionIt project though, a head-up display that provides captions for everyday situations. The hardware is a tiny I²C OLED screen …
It’s said that good things come in small packages, which is hard to deny when we look at all the nifty projects out there that were built into an Altoids tin. Now, if that’s already true for the regular sized box, we can be doubly excited for anything crammed into their Smalls variety ones, which is what …

The developer and mastermind behind the Needle Nose Pliers blog is using a Raspberry Pi Pico to drive a custom audio spectrum analyzer. This project uses the Pico to process audio input and output a visualization of the sound it detects to a small OLED screen in real-time. This project is essentially the same sort of visual …

If you’ve been following my Instructables for a while then you’re probably aware that I like to do unnecessary things, like building a water-cooled Raspberry Pi cluster. This was a fun project but isn’t all that practical for everyday use. So in this Instructable, we’re going to be building a more practical water-cooled Raspberry Pi desktop …

It’s an interesting question: What does one do for a follow-up to building the world’s worst HDMI display? Simple — stick it in a cool steampunk-inspired case and call it a day. That seems to have been [mitxela]’s solution, and please don’t take our assessment as a knock on either the original build or this follow-up. [mitxela] himself expresses …

The cool thing about magnetic tape is that by varying the speed at which you play it back, you can vary the pitch of the output. [Issac] decided to take advantage of this, executing a fancy digitally-controlled pitch mod on his Tascam Porta 02 tape deck. The build uses a Raspberry Pi Pico, which employs PWM …
