George Barlow initially set out to develop a controller to be able to call up a voice preset, and then tweak from there. What he's done is essentially transformed the DX7 synth into an interactive sound designer's dream machine.
Purism makes premium phones, laptops, mini PCs and servers running free software on PureOS. Purism products respect people's privacy and freedom while protecting their security.
A fun project that I learned a lot from.
Whale songs were first noticed by accident, when analysts tracking Russian submarines at the height of the cold war heard cetacean interference instead. An engineer sent some recordings to Roger Payne, a biologist friend of his, who did something that proved pivotal: he played the hours-long recordings on his hi-fi at…
We demonstrate that layered spatial light modulators (SLMs), subject to fixed lateral displacements and refreshed at staggered intervals, can synthesize images with greater spatiotemporal resolution than that afforded by any single SLM used in their construction. Dubbed cascaded displays, such architectures enable…
An unexpected journey for AT&T with it's own low power processor
How Ouster OS1 sensors create 3D HD maps, demonstrated by scanning San Francisco's iconic Ferry Building.
In the excellent Discworld series the character Lord Vetinari has a clock in his waiting room which is designed to tick irregularly in order to make his visitor feel ill at ease. Inspired by a post featured on Hackaday I decided to build my own version of this clock with a simple and easy to make design.
I made a circuit-board business card that opens my website and lights an LED with power harvested from the phone tapping it.
We’re very happy to announce that the source code of the real-time operating system (RTOS) powering the Arduino 101 and Genuino 101 is now available for
Why head to the store when you could simply create your outfits right at home with the touch of a button? That’s the idea behind London-based startup
Explains features that make it easy to program in QED-Forth, including the interactive debugger, floating point mathematics, heap memory manager, arrays and matrices, structures, and the multitasking executive.
How does a vintage airspeed indicator work? CuriousMarc picked one up for a project, but it didn't have any documentation, so I reverse-en...

Today, Arm announced that the first silicon supporting the Morello prototype architecture, a research project led by Arm, Microsoft, University of Cambridge and others, is now available on a limited run of demonstration boards, which are being shipped from today to industry partners for testing. Morello is the first…
Scientists have discovered a group of materials which could pave the way for a new generation of high-efficiency lighting, solving a quandary which has inhibited the performance of display technology for decades. The development of energy saving concepts in display and lighting applications is a major focus of…
Yesterday, together with Holger 'zecke' Freyther, I co-presented at 33C3 about Dissectiong modern (3G/4G) cellular modems. This presentation covers some of our recent explorations into a specific type
Apple II disk controller cards are weird, there are a crazy number of different types , and many are rare and expensive. Can an FPGA-based solution save the day for retro collectors? You bet! Nearly all the existing disk controllers connect the same 8-bit bus to the same 19-pin disk interface, so a universal clone is…
It’s hard to see a child outside today without some kind of iDevice pumping high fidelity 192kbps stereo lossless audio into their shiny white headphones, but BACK IN MY DAY, the iPod hadn’t been invented yet. Pickings were slim. Walkmen were outdated, CD players were pricey and would skip if bumped around despite…
From January to July 2026, I have continued to work on my UK Class 800-inspired train simulator. There are a number of components in progress, but few newly completed: in lieu of posts about completed portions of the simulator, here’s a roundup of progress across the different hardware aspects of the project.

Do you want to get into tinkering and hacking Bluetooth LE devices? Up until now, doing so was very much a DIY process. You would h...
