CinePi Project Promises Open Source Movie Making

November 20, 2023 by Tom Nardi 19 Comments

Today, there’s open source options for pretty much anything mainstream, but that doesn’t mean there aren’t still some niches out there that could benefit from the libre treatment. The CinePi project is a perfect example — before today we didn’t even know that an open hardware and software cinema-quality camera was out there. But now that we do, we can’t wait to see what the community does with it.

Inside the 3D printed enclosure of the CinePi, there’s a Raspberry Pi 4 with HQ camera module, a four-inch touch screen, a Zero2Go power supply with four 18650 cells, and a Notcua fan to keep it all cool. The design intentionally favors modules that are easy to source from the usual online sources. You’ll need to be handy with a soldering iron to follow along with the beautifully photographed assembly guide, but there’s nothing that needs to be custom fabricated to complete the build.

The software was clearly developed with the user experience in mind, and in the video below, you can see how its touch interface makes it easy to change settings on the fly. While an amateur auteur might need to enlist the assistance of their geeky friend to build the CinePi, it doesn’t look like they’ll need them around to help operate it.

Of course, the big question with a project like this: what does the video actually look like? Well the technical answer is that, in terms of raw performance, the CinePi is able to capture 3840 x 2160 CinemaDNG video to an external device such as a NVME SSD or a CFExpress Card at 25 frames per second. But what that actually looks like is going to depend on what kind of post-processing you do to it. For the more practical answer, check out the short film TIMEKEEPER which was shot partially on a CinePi.

If this all looks a bit high-tech for your liking, don’t worry. You could always 3D print yourself a 35 mm movie camera instead.

2023 Halloween Hackfest: This Year’s Spooky Winners

November 20, 2023 by Tom Nardi 1 Comment

With the zombies, ghouls, and ghosts now safely returned to their crypts until next October, it’s time to unveil this year’s winners for the 2023 Halloween Hackfest.

For this contest, sponsors DigiKey and Arduino challenged the community to come up with their best creations for what’s arguably the most hacker-friendly of holidays. Pretty much everything was fair game, from costumes to decorations. The top three winners will get $150 credit from DigiKey and some treats from Arduino — just don’t try to eat them.

That Time NASA Built A Tiny Tank To Pop Shuttle Tires

November 17, 2023 by Tom Nardi 64 Comments

The Space Shuttle has often been called the most complex pieces of machinery ever built, an underhanded compliment if there ever was one. But it’s a claim not strictly limited to the final spacecraft. With a project as far ahead of the technological curve as the Shuttle was in the 1970s, nearly every component and system of the legendary spaceplane required extensive research and development to realize.

A case in point is that the speed and mass of the Shuttle at touchdown required tires that could survive forces far beyond that of a normal airplane. Pumped up to an incredible 350 psi, the space agency estimated each tire had the explosive potential of two and one-half sticks of dynamite. So while testing landing gear upgrades in the 1990s, they cobbled together an RC tank that could “defuse” a damaged tire remotely by drilling holes into it and letting off the pressure.

A Look At All The Badge Hacks Of Supercon 2023

November 15, 2023 by Tom Nardi 6 Comments

For those of you who’ve had the opportunity to join us in Pasadena for Supercon, you’ll know it’s a wild ride from start to finish. Singling out a single moment as our favorite is pretty much impossible, but certainly the Sunday Badge Hacking Ceremony has to rank up there. It’s the culmination of ~78 hours of intense hardware and software hacking, and that’s not even counting the pre-show work that attendees often put into their creations. Every year, without fail, this community manages to pull off badge hacks that are beyond anything we could have imagined — and we’re the ones who made the thing in the first place.

Unfortunately, in the mad rush, we’ve never had a chance to actually photograph the hacked badges and share them with the Hackaday readers. This year, at the urging of some of the badge hackers themselves, we were able to throw together a suitable overhead light at the last minute and actually snapped shots of each badge after it was presented to the audience.

The resulting images, sorted by badge hacking category, are below. While some proved difficult to photograph, especially with an impromptu setup, we’re happy to at least have a complete record of this year’s creations. Hopefully we’ll be able to improve on our technique for 2024 and beyond. If yours shows up, or if you’d like to share your appreciation, sound off in the comments below!

JawnCon 0x0: A Strong Start With A Bright Future

November 13, 2023 by Tom Nardi 9 Comments

Last month, I had the pleasure witnessing a birth. No, not of a child. What I’m talking about is something far rarer, though arguably, just as loud and danger fraught — the birth of a new hacker convention.

The very first JawnCon took place on October 19th and 20th at Arcadia University, just outside of Philadelphia. If you’re in the Northeast US and suddenly find yourself surprised to learn that a hacker con managed to slip under your radar, don’t be. The organizers, who previously helped launch the WOPR Summit back in 2019, wisely decided to keep the scale of this first outing in check. Just a single track of talks, a chill out room, and 130 or like-minded individuals.

Although, even if they’d hatched a more ambitious plan, it’s hard to imagine they’d have had enough time to pull it off. Due to various circumstances, JawnCon had to come together at a breakneck pace, with less than 100 days separating the con’s inception and kickoff. That an event such as this could not only be organized so quickly, but go off without a hitch, is a testament to the incredible folks behind the scenes.

As for what a Jawn is…well, that might take a bit more explaining. It’s regional slang that’s perhaps best described as a universal noun in that it can be used to refer to basically anything or anyone. Think “smurf” or “da kine”. According to organizer Russell Handorf, the all-encompassing nature of the word describes not only his personal ethos but the spirit of the event. Rather than focusing too closely on any one aspect of hacking, JawnCon set out to explore a diverse array of tech topics from both the new and old schools. It would be an event where you could listen to a talk on payphone remote management, try your hand at lock picking, and learn about the latest in anti-drone technology, all under the same roof.

To that end, the team did an incredible job. Everyone I spoke to, young or old, newbie or vet, had a fantastic time. What’s more, as revealed in the Closing Remarks, the con actually managed to stay in the black — no mean feat for a first attempt. With a little luck, it seems like JawnCon is well on its way to becoming one of the Northeast’s can’t-miss hacker events. Continue reading “JawnCon 0x0: A Strong Start With A Bright Future” →

Hackaday Prize 2023: Ending 10 Years On A High Note

November 7, 2023 by Tom Nardi 18 Comments

It’s a fact of life — all good things must eventually come to an end. The trick is not to focus so much on the chapter that’s closing, but look ahead to what comes next. This is precisely how the Hackaday Prize ended its incredible ten-year run on Saturday during Supercon.

This final year of the competition saw some of the most impressive entries we’ve ever had, leaving us with five exceptionally promising winners. These projects exemplify the qualities that the Hackaday Prize was designed to seek out and amplify and make a perfect capstone for this grand experiment in philanthropic hacking.

Random Number Generator Is A Blast From The Past

November 2, 2023 by Tom Nardi 16 Comments

Hackers love random numbers, or more accurately, the pursuit of them. It turns out that computers are so good at following our exacting instructions that they are largely incapable of doing anything that would fit the strict definition of randomness — which has lead to some elaborate methods of generating the unexpected.

Admittedly, the SB42 Random Number Generator built by [Simon Boak] isn’t exactly something you’d be using for cryptography. The method used to generate the digits, a pair of 555 timers sending pulses through linear-feedback shift registers, would at best be considered pseudo-random. Plus the only way of getting the digits out of the machine is by extracting them from the Nixie tubes with your Mark I Eyeballs. But it absolutely excels at the secondary reason many hackers like to build their own randomness rigs — it looks awesome.

Externally, it absolutely nails the look of a piece of vintage DIY year. Down to the classic white-on-black label tape. But open up the hood, and you’re treated to a real rarity these days: wirewrap construction. In an era where you can get PCBs made and shipped to your door for literally pennies, [Simon] is out there keeping the old ways alive. It doesn’t just look the part either. Unlike most modern projects we see, there isn’t a multi-core microcontroller behind the scenes doing all the work, it’s logic gates all the way down.

This isn’t the first random-ish number generator that we’ve seen use shift registers. But if you’re looking for something that might actually pass some randomness checks, and don’t mind working with something a bit spicy, you could check out some of the previous devices we’ve covered that used radioactive decay as an entropy source.
