Gonzo Film Making With The Raspberry Pi

Gonzo journalism has been a hip thing since the 1970s or so, a way of covering a story in a compelling format with more subjectivity and less objectivity. The style has since been applied to all sorts of media, including film—and indeed, the makers of the Gonzo Pi.

The Gonzo Pi is a camera with an open source design, yes, but it’s also a lot more than that. It’s intended to be an entire platform for film-making, all in the one housing. Camera-wise, the design combines a Raspberry Pi with the requisite first-party High Quality Camera, and warps it up in a 3D printed housing. You can build it up with a viewfinder and whatever old-school C-mount or 8 mm film lenses you can lay your hands on.

Beyond that, there’s an editing platform baked in to the device. It’s not unlike the tools in so many social media apps these days. The idea of the Gonzo Pi is that rather than shooting a whole ton of footage and takes and poring over them in great detail later, instead, you run and gun with the device and edit as you go. You can shoot retakes as you need, and even dub in more audio as necessary as you compose your film on the hoof. It’s intended to change the way you make films by virtue of its unique compositional paradigm.

We’ve featured some neat homebrew cameras before, to be sure, but none that quite put the edit suite right in the box.

Raspberry Pi Hack Chat With Eben Upton

Join us on Wednesday, January 15 at noon Pacific for the Raspberry Pi Hack Chat with Eben Upton!

join-hack-chatThe Hack Chat has been on an extended hiatus, but we’re back for 2025 and coming strong out of the gate! We’ve been trying to get Raspberry Pi co-founder and CEO Eben Upton on the chat for a while, but there was that whole thing of taking the company public that probably distracted him a wee bit. That’s fine though, because we know he loves getting in the trenches with the hacker community and talking about the things we all love to talk about. It’s not often that you get a chance for a one-on-one like this, so make sure you join us with all your Pi-related questions.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, January 15 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.

LED Wall Clock Gets Raspberry Pi Pico Upgrade

When [Rodrigo Feliciano] realized that the reason his seven-segment LED wall clock wasn’t working was because the original TG1508D5V5 controller was fried, he had a decision to make. He could either chuck the whole thing, or put in the effort to reverse engineer how the displays were driven and replace the dead controller with something a bit more modern. Since you’re reading this post on Hackaday, we bet you can guess which route he decided to take.

If you happen to own the same model of clock as [Rodrigo], then you really lucked out. He’s done a fantastic job documenting how he swapped the original controller out for a Raspberry Pi Pico W, which not only let him bring the clock back to life, but let him add new capabilities such as automatic time setting via Network Time Protocol (NTP).

But even if you don’t have this particular clock there’s probably something you can learn from this project, as it’s a great example of practical reverse engineering. By loading a high-resolution image of the back of the PCB into KiCad, [Rodrigo] was able to place all the components into their correct positions and following traces to see what’s connected to what.

Pretty soon he not only had a 3D model of the clock’s PCB, but a schematic he could use to help wire in the Pi Pico. Admittedly this is a pretty straightforward PCB to try and reverse engineer, but hey, you have to start somewhere.

We had high hopes for KiCad’s image import feature when it was introduced, and it’s great to see real-world examples like this trickle in as more folks learn about it.

Hackaday Podcast Episode 301: Hacking NVMe Into Raspberry Pi, Lighting LEDs With Microwaves, And How To Keep Your Fingers

Twas the week before Christmas when Elliot and Dan sat down to unwrap a pre-holiday bundle of hacks. We kicked things off in a seasonally appropriate way with a PCB Christmas card that harvests power from your microwave or WiFi router, plus has the potential to be a spy tool. We learned how to grow big, beautiful crystals quickly, just in case you need some baubles for the tree or a nice pair of earrings. Speaking of last-minute gifts, perhaps you could build a packable dipole antenna, a very durable PCB motor, or a ridiculously bright Fibonacci simple add-on for your latest conference badge. We also looked into taking a shortcut to homebrew semiconductors via scanning electron microscopes, solved the mystery of early CD caddies, and discussed the sad state of table saw safety and the lamentable loss of fingers, or fractions thereof.

Old BBC Micro Gets Some Disk Help From A Raspberry Pi

[Peter Mount] had a simple problem. He’d treated himself to a retro purchase in the form of a BBC Master 128—a faster sequel to the BBC Micro Model B. The only problem was he needed a way to get software on to it. Cue a creative hack using a Raspberry Pi Zero W.

When [Peter] received the machine, it already had a GoTek floppy emulator, which pulled disk images off a USB drive. However, he wanted an easier and quicker way to get disk images to and from the machine for development purposes. Swapping the USB drive to and from another machine seemed too tedious.

Instead, he decided to swap in a Pi Zero W for this purpose, setting it up to emulate a flash drive by following instructions from MagPi Magazine. This would allow him to use the SCP tool to copy disk images over to the Pi Zero W via its WiFi connection. Basically, the Pi Zero W was acting as a wirelessly-updated storage device hooked up to the GoTek floppy emulator.

It’s a nifty way of doing things. [Peter] could have set about creating his own floppy emulator from scratch with wireless capability included. However, there was no need. He just needed a wirelessly-accessible USB drive, and the Pi Zero W was more than happy to act in that role.

The BBC Micro is a beloved machine of many in the British Isles, and it had rather an extended family. If you’ve pulled off your own nifty hack on this classic machine, be sure to hit us up on the tipsline!

Enabling NVMe On The Raspberry Pi 500 With A Handful Of Parts

With the recent teardown of the Raspberry Pi 500, there were immediately questions raised about the unpopulated M.2 pad and related traces hiding inside. As it turns out, with the right parts and a steady hand it only takes a bit of work before an NVMe drive can be used with the RP500, as [Jeff Geerling] obtained proof of. This contrasts with [Jeff]’s own attempt involving the soldering on of an M.2 slot, which saw the NVMe drive not getting any power.

The missing ingredients turned out to be four PCIe coupling capacitors on the top of the board, as well as a source of 3.3 V. In a pinch you can make it work with a bench power supply connected to the pads on the bottom, but using the bottom pads for the intended circuitry would be much neater.

This is what [Samuel Hedrick] pulled off with the same AP3441SHE-7B as is used on the Compute Module 5 IO board. The required BOM for this section which he provides is nothing excessive either, effectively just this one IC and required external parts to make it produce 3.3V.

With the added cost to the BOM being quite minimal, this raises many questions about why this feature (and the PoE+ feature) were left unpopulated on the PCB.

Raspberry Pi 500 And The Case Of The Missing M.2 Slot

Raspberry Pi just dropped the new Raspberry Pi 500, which like its predecessor puts the similarly named SBC into a keyboard. In a detailed review and teardown video, [Jeff Geerling] goes over all the details, and what there is to like and not like about this new product.

Most of the changes relative to the RP400 are as expected, with the change to the same BCM2712 SoC as on the Raspberry Pi 5, while doubling the RAM to 8 GB and of course you get the soft power button. As [Jeff] discovers with the teardown, the odd thing is that the RP500 PCB has the footprints for an M.2 slot, as seen on the above image, but none of the components are populated.

Naturally, [Jeff] ordered up some parts off Digikey to populate these footprints, but without luck. After asking Raspberry Pi, he was told that these footprints as well as those for a PoE feature are there for ‘flexibility to reuse the PCB in other contexts’. Sadly, it seems that these unpopulated parts of the board will have to remain just that, with no M.2 NVMe slot option built-in. With the price bump to $90 from the RP400’s $70 you’ll have to do your own math on whether the better SoC and more RAM is worth it.

In addition to the RP500 itself, [Jeff] also looks at the newly launched Raspberry Pi Monitor, a 15.6″ IPS display for $100. This unit comes with built-in speakers and VESA mount, but as [Jeff] notes in his review, using this VESA mount also means that you’re blocking all the ports, so you have to take the monitor off said VESA mount if you want to plug in or out any cables.
