In November last year — I started building a DIY security alarm system, using a Raspberry Pi as the controller. My plan was to make a self-sustained system, using proper alarm hardware — like PIR sensors and sirens. Integration with Home Assistant would be an add-on, not a requirement. I wanted the system to be as…
Over at MacRumors, Hartley Charlton pointed out something that hadn’t crossed my mind: Historically, Apple released at least one new Mac model every year in the fourth quarter that runs between October and December, starting in 2001 with the launch of the iBook G3. This means that there has been a new Mac toward the…
A generous member of the wider curl community stepped up and donated an unused Mac mini m1 model to me to be used for curl development. Today it arrived at my home. An 8C CPU/16GB/1TB/8C GPU/1GbE model as per the sticker on the box. The m1 mac mini, still wrapped in plastic. Apple is not … Continue reading An m1 for…
But there’s only one slot, you say? It’s all a matter of using a clever part to adapt a pass-through.
In 2022 a consortium of companies ran an international competition, called the ZPrize, to advance the state of the art in “zero-knowledge” cryptography. We d...
Wi-Fi networking provides us with 2 bands for the operation of wireless LAN networks: the 2.4Ghz band and the 5GHz band. The 2.4GHz band has...
I've stumbled across a technique for drawing holograms directly upon a plastic plate by hand. It sounds impossible, but I've been sitting on the livingroom sofa making holographic images of floating polyhedra, words, 3D starfields, opaque objects, etc. No laser, no isolation table, no darkroom, no expensive film…
Bodging a rotary dial into a mechanical keyboard
For decades, we've asked ourselves "Can it run Doom?". Now we can finally make the ultimate punchline: "Can Doom run it?"

I present to you: The GB Interceptor. It is an adapter that goes between an unmodified Game Boy and the cartridge and offers a video stream of the game via USB. Click the image to see the video on youtube.com. The video above should give you a good overview of what it does, how it works and what its limitations are…
As I mentioned in my last post, I spent a good chunk of my spare time over the past 6 months working on a project I’ve been thinking about for over a decade. I bought a Chumby 8 in 2011. It’s an 8″ touchscreen device powered by the Marvell PXA166 processor. It is essentially a souped-up digital picture frame with…
“ Secure Element ” (SE) chips have traditionally taken a very closed-source, NDA-heavy approach. Thus, it piqued my interest when an early-stage SE chip startup, Cramium (still in stealth mode), approached me to advise on open source strategy. This blog post explains my reasoning for agreeing to advise Cramium, and…
The tandem solar cell converts 32.5% of the incident solar radiation into electrical energy. This value is now officially certified and included in the NREL chart.
Any ‘computer’ is made up of hundreds of separate computers plugged together, any of which can be hacked. I list some of these parts.
One of the more common arguments you hear in contemporary computer security circles is about hardware trust and embedded controllers. Technologies like Intel ME, the ARM Secure Element, TPMs, etc, remind us that the architecture of the modern computer is complex and not entirely under our control. A typical modern…
Yes, you read that right... for $8 you can run linux on a RISC-V computer. And not just a stripped down kernel without an MMU. No, t...
This post is going yet another part in the DIY camera projects which have been doing since quite some time. In this post I will showi...
Additionally, Exegin Technologies has demoed how Z-Wave Source Code can be ported to third-party silicon, opening members to develop on any chip provider of their choice. Beaverton, OR – December […]
Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonised economy.
An expensive and unreliable way to record low quality videos!

This technical guide details how you can create your own orthorectified (aka satellite view/bird mode) imagery, point clouds and 3D models of streets with nothing but a 360 degree camera mounted on bicycle helmet, and the open source photogrammetry software OpenDroneMap.
Creating the PiRS232 and playing with the Pi over serial has been leading towards an idea - I wanted to create a small, battery powered device, a sidecar that I could carry with my Psion and use as portable Linux terminal. I also managed to turn it into an Internet...
Could VR-powered humanoid robots be the future of heavy construction? Over the years we’ve seen a number of major corporations try their hands at marrying VR technology and robotics, from VR convenience store employees and a remote-controlled bomb squad bot to a rather unsettling headset that uses a robotic arm to…
Meter is currently tracking an issue that is affecting M1/M2 Macbooks and leading to slow internet connection, drops in Zoom calls, and entirely losing a Wi-Fi connection.
Christmas is coming again, and generally that means christmas trees and everything in it: lights, streamers, and ofcourse baubles. The holiday is all very jolly and everything, so I decided it was lacking some doom... errm, I mean Doom. So I 3d-printed a small Christmas bauble modeled on an IBM PC, stuffed it with the…
