Two For The Price Of One: BornHack 2024 And 2025 Badges

August 1, 2025 by No comments

BornHack is a week-long summer hacker camp in a forest on the Danish island of Fyn, that consistently delivers a very pleasant experience for those prepared to make the journey. This year’s version was the tenth iteration of the camp and it finished a week ago, and having returned exhausted and dried my camping gear after a Biblical rainstorm on the last day, it’s time to take a look at the badges. In case you are surprised by the plural, indeed, this event had not one badge but two. Last year’s badge suffered some logistical issues and arrived too late for the camp, so as a special treat it was there alongside the 2025 badge for holders of BornHack 2024 tickets. So without further ado, it’s time to open the pack for Hackaday and see what fun awaits us. Continue reading “Two For The Price Of One: BornHack 2024 And 2025 Badges” →

Hackaday Podcast Ep 331: Clever Machine Tools, Storing Data In Birds, And The Ultimate Cyberdeck

August 1, 2025 by 5 Comments

Another week, another Hackaday podcast, and for this one Elliot is joined by Jenny List, fresh from the BornHack hacker camp in Denmark.

There’s a definite metal working flavour to this week’s picks, with new and exciting CNC techniques and a selective electroplater that can transfer bitmaps to metal. But worry not, there’s plenty more to tease the ear, with one of the nicest cyberdecks we’ve ever seen, and a bird that can store images in its song.

Standout quick hacks are a synth that makes sounds from Ethernet packets, and the revelation that the original PlayStation is now old enough to need replacement motherboards. Finally we take a closer look at the huge effort that goes in to monitoring America’s high voltage power infrastructure, and some concerning privacy news from the UK. Have a listen!

And/or download your own freshly-baked MP3, full of unadulterated hacky goodness.

A Proper Computer For A Dollar?

August 1, 2025 by 29 Comments

When a tipster came to us with the line “One dollar BASIC computer”, it intrigued us enough to have a good look at [Stan6314]’s TinyBasRV computer. It’s a small PCB that forms a computer running BASIC. Not simply a microcontroller with a serial header, this machine is a fully functioning BASIC desktop computer that takes a PS/2 keyboard and a VGA monitor. Would that cheap price stand up?

The board uses a CH32 microcontroller, a RISC-V part that’s certainly very cheap indeed and pretty powerful, paired with an I2C memory chip for storage. The software is TinyBASIC. There’s some GPIO expandability and an I2C bus, and it’s claimed it can run in headless mode for a BASIC program to control things.

We haven’t added up all the parts in the BoM to check, but even if it’s not a one dollar computer it must come pretty close. We can see it could make a fun project for anyone. It’s certainly not the only small BASIC board out there, it’s got some competition.

Thanks [Metan] for the tip.

When Online Safety Means Surrendering Your ID, What Can You Do?

July 31, 2025 by 92 Comments

A universal feature of traveling Europe as a Hackaday scribe is that when you sit in a hackerspace in another country and proclaim how nice a place it all is, the denizens will respond pessimistically with how dreadful their country really is. My stock response is to say “Hold my beer” and recount the antics of British politicians, but the truth is, the grass is always greener on the other side.

There’s one thing here in dear old Blighty that has me especially concerned at the moment though, and perhaps it’s time to talk about it here. The Online Safety Act has just come into force and is the UK government’s attempt to deal with what they perceive as the nasties on the Internet, and while some of its aspirations may be honourable, its effects are turning out to be a little chilling.

As might be expected, the Act requires providers to ensure their services are free of illegal material, and it creates some new offences surrounding sharing images without consent, and online stalking. Where the concern lies for me is in the requirement for age verification to ensure kids don’t see anything the government things they shouldn’t, which is being enforced through online ID verification. There are many reasons why this is of concern, but I’ll name the three at the top of my list.

Farewell Shunsaku Tamiya: The Man Who Gave Us The Best Things To Build

July 31, 2025 by 34 Comments

In the formative experiences of most Hackaday readers there will almost certainly be a number of common threads, for example the ownership of a particular game console, or being inspired into engineering curiosity by the same TV shows. A home computer of a TV show may mark you as coming from a particular generation, but there are some touchstones which cross the decades.

Of those, we are guessing that few readers will not at some point have either built, owned, or lusted after a Tamiya model kit at some point over the last many decades, so it’s with some sadness that we note the passing of Mr. Tamiya himself, Shunsaku Tamiya, who has died at the age of 90.

A Dual-Screen Cyberdeck To Rule Them All

July 30, 2025 by 13 Comments

We like cyberdecks here at Hackaday, and in our time we’ve brought you some pretty amazing builds. But perhaps now we’ve seen the ultimate of the genre, a cyberdeck so perfect in its execution that this will be the machine of choice in the dystopian future, leaving all the others as mere contenders. It comes courtesy of [Sector 07], and it’s a machine to be proud of.

As with many cyberdecks, it uses the Raspberry Pi as its powerhouse. There are a couple of nice touchscreens and a decent keyboard, plus the usual ports and some nice programmable controls. These are none of them out of the ordinary for a cyberdeck, but what really shines with this one is the attention to detail in the mechanical design. Those touchscreens rotate on ball bearings, the hinges are just right, the connections to the Pi have quick release mechanisms, and custom PCBs and ribbon cables make distributing those GPIOs a snap.

On top of all that the aesthetics are on point; this is the machine you want to take into the abandoned mining base with you. Best of all it’s all available from the linked GitHub repository, and you can marvel as we did at the video below the break.

If you hunger for more cyberdecks, this one has some very stiff competition.

The Power-Free Tag Emulator

July 27, 2025 by 12 Comments

Most of you know how an NFC tag works. The reader creates an RF field that has enough energy to power the electronics in the tag; when the tag wakes up, two-way communication ensues. We’re accustomed to blank tags that can be reprogrammed, and devices like the Flipper Zero that can emulate a tag. In between those two is [MCUer]’s power-free tag emulator, a board which uses NFC receiver hardware to power a small microcontroller that can run emulation code.

The microcontroller in question is the low-power CW32L010 from Wuhan Xinyuan Semiconductor, a Chinese part with an ARM Cortex M0+ on board. Unfortunately, that’s where the interesting news ends, because all we can glean from the GitHub repository is a PCB layout. Not even a circuit diagram, which we hope is an unintended omission rather than deliberate. It does, however, lend itself to the fostering of ideas, because if this designer can’t furnish a schematic, then perhaps you can. It’s not difficult to make an NFC receiver, so perhaps you can hook one up to a microcontroller and be the one who shares the circuit.
