Raspberry Pi Files Paperwork With The London Stock Exchange

If you’re a regular visitor to the Raspberry Pi website and you have a sharp eye, you may have noticed during the last few days a new link has appeared in their footer. Labelled “Investor relations“, it holds links to the documents filed with the London Stock Exchange of their intention to float. In other words, it’s confirmation of their upcoming share offering.

It has been interesting to watch the growth of Raspberry Pi over the last twelve years, from cottage industry producing a thousand boards in China, to dominating the SBC market and launching their own successful silicon. Without either a crystal ball or a window into Eben Upton’s mind, we’re as unreliable as anyone else when it comes to divining their future path. But since we’re guessing that it will involve ever more complex silicon with a raspberry logo, it’s obvious that the float will give them the investment springboard they need.

For those of us who have been around for a long time this isn’t the first company in our corner of the technology world we’ve seen burn brightly. It’s not even the first from Cambridge. Appointing ourselves as pundits though, we’d say that Raspberry Pi’s path to this point has been surprisingly understated, based upon the strength of its products rather than hype, and while Eben is undoubtedly a well-known figure, not based upon a cult of personality. There is already a significant ecosystem around Raspberry Pi, we’d like to think that this move will only strengthen it. We may not be looking at the British Microsoft, but we don’t think we’re looking at another Sinclair either.

Raspberry Pi Narrates (And Tattles On) Your Cat, Nature Documentary Style

Detecting a cat with a raspberry pi and camera is one thing, but [Yoko Li]’s AI Raspberry Pi Cat Detection brings things entirely to another level by narrating your feline’s activities, nature documentary style.

The project is ostensibly aimed at tattling on the housecats by detecting forbidden behavior such as trespassing on the kitchen counter. But we daresay that’s overshadowed by the verbose image analysis, which describes the scene in its best David Attenborough impression.

This feline exemplifies both the beauty and the peaceful nature of its kind. No email will be sent as the cat is not on the kitchen counter.

Hard to believe that just a few years ago this cat detector tool was the bee’s knees in cat detection technology. Things have certainly come a long way. Interested? The GitHub repository has everything needed to roll your own and we highly recommend watching it in action in the video, embedded below.

How Does The Raspberry Pi Rack Up Against A Mini PC?

When the first Raspberry Pi came out back in 2012 it was groundbreaking because it offered a usable little Linux machine with the proud boast of a $25 dollar price tag. Sure it wasn’t the fastest kid on the block, but there was almost nothing at that price which could do what it did. Three leap years later though it’s surrounded by a host of competitors with similar hardware, and its top-end model now costs several times that original list price.

Meanwhile the cost of a “real” x86 computer such as those based upon the Intel N100 has dropped to the point at which it almost matches a fully tricked-out Pi with storage and peripherals, so does the Pi still hold its own? [CNX Software] has taken a look.

From the examples they use, in both cases the Intel machine is a little more expensive than the Pi, but comes with the advantage of all the peripherals, cooling, and storage coming built-in rather than add-ons. They rate the Pi as having the advantage on expandability as we’d expect, but the Intel giving a better bang for the buck in performance terms. From where we’re sitting the advantage of the Pi over most of its ARM competition has always been its good OS support, something which is probably exceeded by that on an x86 platform.

So, would you buy the Intel over the high-end Pi? Let us know in the comments.

A red 3D-printed Raspberry Pi-based document scanner

Raspberry Pi Scanner Digitizes On The Cheap

It’s pretty important in 2024 to be able digitize documents quickly and easily without necessarily having to stop by the local library or buy an all-in-one printer. While there are plenty of commercial solutions out there, [Caelestis Cosplay] has created a simple document scanner that takes documents, as [Caelestis Cosplay] puts it, from papers to pixels.

The build is probably what you’re expecting — it’s essentially a Raspberry Pi (in this case a 4B), a V2 Pi camera, and a handful of custom 3D-printed parts. [Caelestis Cosplay] says they had never designed anything for printing before, and we think it looks great. There’s also a buzzer to indicate that the scan is starting (one beep) or has completed (two beeps), a ‘ready’ indicator, and a ‘working’ indicator.

Everything you’d need to build your own is available over on Instructables, including document scanner and controller scripts. Be sure to check it out in action after the break, and see it quickly scan in a document and put it on a thumb drive.

Looking for a 3D scanner? Check out the OpenScan project.

The Next Evolution Of The Raspberry Pi Recovery Kit

At Hackaday, the projects we cover are generally a one-off sort of thing. Somebody makes something, they post it online, we share it with our audience — rinse and repeat. If a project really captures people’s imaginations, it might even inspire a copy or two, which is gratifying for everyone involved. But on the rarest of occasions, we run across a project like [Jay Doscher]’s Recovery Kit.

To say that the Recovery Kit was an inspiration to others would be putting it mildly. Revolutionary would be more like it, as it resulted in more “Pi-in-a-Pelican” builds than we could possibly count. So it’s only natural that [Jay] would return to the well and produce a second version of his heavy-duty cyberdeck.

Infotainment system playing back from USB. (Folkert van Heusden)

Create Virtual USB Sticks With A Raspberry Pi Zero

Playing back music files from USB sticks is a common feature these days, and is built-into the infotainment system in [Folkert van Heusden]’s Opel Astra. Unfortunately such USB playback features often come with a range of limitations on things like audio codecs, and in the case of [Folkert]’s car, a 1000 file limit. This had him looking at an alternative to lugging a lot of USB sticks around to avoid the horror of hearing the same songs within a week while commuting. The solution? Make a Raspberry Pi Zero into a virtual USB mass storage device using the Mass Storage Gadget (MSG) driver in the Linux kernel.

Picking USB storage as the ideal option here comes mostly from the age of the infotainment system, which lacks Bluetooth, and the audio input jack is rather crackly. Of course, having the Raspberry Pi Zero pretend to be a storage device via the MSG driver wouldn’t solve the file limit, but to get around this two Python scripts were written: one which creates images from a folder of music files, and another which randomly picks one of the available images from the Zero’s SD card and configures the MSG driver to use it.

As for the list of future improvements, there is mounting the RPi Zero’s SD card as read-only to deal with the power-off when the car is shut down, and the creating of images requires to be run as root due to the use of loopback devices. As a Proof-of-Concept it does seem to be on the right track.

It’s not just the older infotainment systems that get to have all the fun. If you’re lucky enough to have Linux running in the dashboard, you might be little more than a Bash script away from bending the system to your will.

FLOSS Weekly Episode 772: Raspberry Pi From The Man Himself

This week, Jonathan Bennett and Elliot Williams talk with Eben Upton about the Raspberry Pi! The conversation covers the new Pi 5, the upcoming CM5, the possible Pi500, and the Initial Public Offering (IPO) that may happen before too long. There’s also the PCIe port, the RP1, and the unexpected effects of using Broadcom chips. And then we ask the Billion Dollar question: What’s the money from an IPO going to fund? New hardware, software upgrades, better documentation? Nope, and the answer surprised us, too.
