38C3: Save Your Satellite with These Three Simple TricksBEESAT-1 is a 1U cubesat launched in 2009 by the Technical University of Berlin. Like all good satellites, it has redundant computers onboard, so when the first one failed in 2011, it just switched over to the second. And when the backup failed in 2013, well, the satellite was “dead” — or rather sending back all zeroes. Until [PistonMiner] took a look at it, that is.
Getting the job done required debugging the firmware remotely — like 700 km remotely. Because it was sending back all zeroes, but sending back valid zeroes, that meant there was something wrong either in the data collection or the assembly of the telemetry frames. A quick experiment confirmed that the assembly routine fired off very infrequently, which was a parameter that’s modifiable in SRAM. Setting a shorter assembly time lead to success: valid telemetry frame.
Then comes the job of patching the bird in flight. [PistonMiner] pulled the flash down, and cobbled together a model of the satellite to practice with in the lab. And that’s when they discovered that the satellite doesn’t support software upload to flash, but does allow writing parameter words. The hack was an abuse of the fact that the original code was written in C++. Intercepting the vtables let them run their own commands without the flash read and write conflicting.
Of course, nothing is that easy. Bugs upon bugs, combined with the short communication window, made it even more challenging. And then there was the bizarre bit with the camera firing off after every flash dump because of a missing break in a case statement. But the camera never worked anyway, because the firmware didn’t get finished before launch.
Challenge accepted: [PistonMiner] got it working, and after fifteen years in space, and ten years of being “dead”, BEESAT-1 was taking photos again. What caused the initial problem? NAND flash memory needs to be cleared to zeroes before it’s written, and a bug in the code lead to a long pause between the two, during which a watchdog timeout fired and the satellite reset, blanking the flash.
This talk is absolutely fantastic, but may be of limited practical use unless you have a long-dormant satellite to play around with. We can nearly guarantee that after watching this talk, you will wish that you did. If so, the Orbital Index can help you get started.

Release Your Inner Ansel Adams With The Shitty Camera ChallengeSocial media microblogging has brought us many annoying things, but some of the good things that have come to us through its seductive scrolling are those ad-hoc interest based communities which congregate around a hashtag. There’s one which has entranced me over the past few years which I’d like to share with you; the Shitty Camera Challenge. The premise is simple: take photographs with a shitty camera, and share them online. The promise meanwhile is to free photography from kit acquisition, and instead celebrate the cheap, the awful, the weird, and the wonderful in persuading these photographic nonentities to deliver beautiful pictures.
Where’s The Hack In Taking A Photo?
Of course, we can already hear you asking where the hack is in taking a photo. And you’d be right, because any fool can buy a disposable camera and press the shutter a few times. But from a hardware hacker perspective this exposes the true art of camera hacking, because not all shitty cameras can produce pictures without some work.
The #ShittyCameraChallenge has a list of cameras likely to be considered shitty enough, they include disposables, focus free cameras, instant cameras, and the cheap plastic cameras such as Lomo or Holga. But also on the list are models which use dead film formats, and less capable digital cameras. It’s a very subjective definition, and thus in our field everything from a Game Boy camera or a Raspberry Pi camera module to a home-made medium format camera could be considered shitty. Ans since even the ready-made shitty cameras are usually cheap and unloved second-hand, there’s a whole field of camera repair and hacking that opens up. Finally, here’s a photography competition that’s fairly and squarely on the bench of Hackaday readers.

A Whole World Of Shitty Awesomeness Awaits!
Having whetted your appetite, it’s time to think about the different routes into camera hacking. Perhaps the simplest is to take a camera designed for an obsolete film format, and make a cartridge or spool that takes a commonly available film instead. Perhaps resurrecting an entire home movie standard is a little massochistic, but Thingiverse is full of 3D-printable adapters for more everyday film. Or you could make your own, as I did for my 1960s Agfa Rapid snapshot camera.
If hacking film cartridges seems a little low-tech, a camera whether film or digital is a simple enough device mechanically that making your own is not out of the question. At its simplest a pinhole camera can be made from trash, but we think if you’re handy with a CAD package and a 3D printer you should be able to do something better. Don’t be afraid to combine self-made parts with those from manufactured cameras; when every second hand store has a pile of near-worthless old cameras for relative pennies it makes sense to borrow lenses or other parts from this boanaza. And finally, you don’t need to be a film lover to join the fun, if a Raspberry Pi or an ESP cam module floats your boat, you can have a go at the software side too. As a hint, take a look on AliExpress for a much wider range of camera modules and lenses than the ones supplied with either of these boards.
This Polaroid is a lot of camera for ten quid!
If I’m exhorting readers to have a go with a shitty camera then, perhaps I should lead by example. Past entries of mine have come from that Agfa Rapid cartridge I mentioned, but for their current outing I’ve gone for a mixture of new and old. The new isn’t a hack, I just like those toy cameras with the thermal printers, but the old one has been quite a project. Older consumer grade Polaroid pack film instant cameras are particularly unloved, so I’ve 3D-printed a new back for mine that takes a 120 roll film. It’s an ungainly camera to take to the streets with, but now I’ve finished all that 3D printing I hope I’ll get those elusive dreamy black and white landscapes on my poll of FomaPan 100.
If you want to try the #ShittyCameraChallenge, hack together a shitty camera and get shooting. Its current iteration lasts until the 1st of February, so you should have some time left to post your best results on Mastodon. Good luck!

“I’m hoping that one day the passion will come back” Fatboy Slim says he “just don’t seem to feel like” making music anymoreRetirement may not be on the cards for Fatboy Slim just yet, but you’d be hard pressed to find the 61-year-old DJ and producer putting on his music-making hat ever again.
The musician, real name Norman Cook, recently told The Sun’s Bizarre column that he’ll much rather focus his energies on DJing than release new music because “you can’t make music unless you’re absolutely passionate about it”.

“My last two singles just came out of a live show. They were both things that I made just to play on the side,” says Cook, who earlier this year released the single Bus Stop Please along with Daniel Steinberg.
“I had tunes that nobody else had in my set. And that kind of caught on with people when we worked out that we could clear the samples and release them. The thing is, you can’t make music unless you’re absolutely passionate about it and it drives you from the moment you wake up in the morning.”
“I just don’t seem to feel like that any more,” Cook admits. “I feel like that about DJing and about putting on things like this, but I’ve kind of lost my passion for making music.”
“For five years, I tried to beat myself up about it and go, ‘You should be doing this’. But then I thought, ‘Well, everybody likes my DJing and I enjoy that more, so I’ll do that.’”
“I’m hoping that one day the passion will come back,” he says.
Meanwhile, Fatboy Slim recently shared some DJing tips for the holidays, noting how it’s not so much about getting people dancing as much as it is about “unifying people”.
“The dance floor is like an organism, and when it’s all working together, it’s lovely, but sometimes you lose the dancefloor,” he said. “There’s sort of different pockets of people and they’re not really united. Or some people are dancing, some people aren’t, and it’s that feeling of bonding everybody together that you need to do, and recognition of a song that everybody likes is kind of that thing.”
“For me, if I really had to rescue a dance floor I’d play Right Here, Right Now or Praise You. They would be my get-out-of-jail records.”

Beam me Up: Simple Free-Space Optical CommunicationLet’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams. Forget expensive lasers or commercial-grade equipment; this video by [W1VLF] offers a simple and cheap entry point for anyone with a curiosity for DIY tech. Inspired by a video on weak signal sources for optical experiments, this project uses everyday components like a TV remote-control infrared LED and a photo diode. The goal is simply to establish optical communication across distances for under $10.
Click through the break to see more…
The heart of this setup is a basic pulse-width modulator driving the LED. Pair it with a photo diode for reception, and voilà—light beams become data carriers. Add a lens for focus, and you’ll instantly see the dramatic signal gain. LEDs from remote controls are surprisingly effective. For more precision, swap to narrow-beam LEDs or use filtered photo diodes to block ambient noise from sunlight or fluorescent lights. It’s delightfully simple yet endlessly tweakable.
[W1VLF]’s advice: start small, but don’t stop there—enthusiasts have built entire FSO networks to link rural areas! If you’re intrigued, [W1VLF] has more videos to explore. Want to dig deeper into the history of optical communications?  We’ve got that!  Once you advance, share your tips and thoughts in the comments below to help others get set up.

38C3: Xobs on Hardware DebuggersIf you just want to use a debugger for your microcontroller project, you buy some hardware device, download the relevant driver software, and fire up GDB. But if you want to make a hardware debugger yourself, you need to understand the various target chips’ debugging protocols, and then you’re deep in the weeds. But never fear, Sean [Xobs] Cross has been working on a hardware debugger and is here to share his learnings about the ARM, RISC-V, and JTAG debugging protocols with us.
He starts off with a list of everything you need the debugger hardware to be able to do: peek and poke memory, read and write to the CPU registers, and control the CPU’s execution state. With that simple list of goals, he then goes through how to do it for each of the target chip families. We especially liked [Xobs]’s treatment of the JTAG state machine, which looks pretty complicated on paper, but in the end, you only need to get it in and out of the shift-dr and shift-ir states.

This is a deep talk for sure, but if you’re ever in the throes of building a microcontroller programmer or debugger, it provides a much-appreciated roadmap to doing so.
And once you’ve got your hardware setup, maybe it’s time to dig into GDB? We’ve got you covered.
