Back in 2015, I had the idea for gpiozero — a Python library for Raspberry Pi, making programming GPIO devices simpler by abstraction: instead of thinking about pin channels, voltages, pull-up resistors and rising or falling edges, we think about buttons being pressed and released, sensors...
One day there will hopefully be a house on this land Over the last year, I admittedly haven’t used my Vision Pro a ton, but fairly recently I discovered a super handy use that it’s absolutely incredible at, provided you have the right tools. After years of apartment life my girlfriend and I have recently begun the…
TL;DR: DIY home automation is ezpz with nothing more than a stepper motor, an esp32, and a high tolerance for Jank. My rental apartment’s AC unit can only be controlled using these retro-looking analog knob-based controls, mounted right onto the unit. No separate wall-mounted thermostat, no remote…
A collection of Maroš Grego's works.
Plane radar is a neat little project that pulls nearby ADS-B traffic, plots each aircraft by distance and bearing, and shows the details directly on a cute little screen.
Changes proposed for ADB could kill an entire ecosystem of open-source power-user apps, mobile developer setups, and rootless privacy tools based on Shizuku.
i dissected some firmware for a Hanwha Wisenet XNP-9300RW and found that it had github admin tokens in it, also miltech is weird
This computer was so good and so far out there, we didn't know what we had.
The Fairphone 6 is an interesting target for mainline Linux and postmarketOS for a few reasons:
Designing the world's first open source Ethernet switch ASIC. An unmanaged cut-through 3-port 100Mbps switch fabbed on Global Foundries 180 nm.
This article was written by a human, for humans. Phantomdrive is now available from the Rootkit Labs shop. Many places don’t respect privacy …
I bought an NVIDIA DGX Spark! It's actually quite a competent general purpose computer while being super tiny and power efficient. It basically just has an ARM CPU, a decent NVIDIA GPU (with the same number of CUDA cores as the RTX 5070), 128 GB of unified memory, and a 4 TB SSD.
Hamming Codes ECC RAM corrects errors that occur in memory before it gets to the CPU. The most common form of ECC is the Hamming Code [1] which when it has R redundant bits can correct single bit e…
What Chip Weinberger learned building and selling 2500 Jamcorder MIDI recorders.
Coming to a Panther Lake notebook near you!
As of writing, the Zilog Z80 processor was officially launched 50 years ago, in July of 1976, less than 4 years after the last human had walked on the moon, decades closer to WWII than to the present day, roughly at a half way point between the Kennedy assassination and the fall of the Berlin wall, closer to the…
TL;DR: is your refrigerator running malware? If so, you better catch it!
My wife and I recently went on a 7 week holiday around Europe. Although we each took a massive backpack, we wanted to travel fairly lightly. I took a single universal power brick. This little unit was all I needed to charge my various gadgets. It has a hefty USB-C PD (Power Delivery) port for rapid charging of my…
KO | EN | Discussions on HN I still have a netbook I bought back in 2009. The ASUS Eee PC 1000HE has an Intel Atom N280 and 1GB of DDR2 RAM. The Atom N series was Intel’s line of cheap, low-performance CPUs for netbooks. The chip has 56KB of L1 cache and 512KB of L2 cache, and its clock speed is 1.6...
How wanting more is not always better
Decommissioned enterprise tesla GPUs are widely available and extremely cheap. In this post, I benchmark tesla GPUs to see if they are useful
About a couple months ago I purchased an Arduino Nano ESP32 dev board. I had this sudden itch and I wanted to play around with hardware. I don't really have much experience in this space, besides working on firmware for an IoT company over a decade ago, but I've written tons of software over the years. I was very…
The recent end-of-financial-year sales were rather interesting – I found myself spending a lot more time browsing AliExpress than I did Amazon or eBay this year which is something I wouldn…
In 1993, Jurassic Park came out and revolutionized the use of CGI in films [1] . To the public the experience was magic. But for some of the people in the movie industry, it was a rude awakening.
In our kitchen, the only device that displays the time is our oven! :D Looking at it was always a bit annoying.
The QuadRF (pictured above) a phased-array radio built around a Raspberry Pi 5 and an FPGA board with picosecond-level timing. It does advanced signal processing and beamforming. It can see WiFi through walls and track drones in flight. If the open source community can come up with something like this, just imagine…
You stumble on a weird robot chassis in an industrial warehouse. Its adorable, enormous and will likely be scrapped.
The challenges around porting Linux to an old videogame console by Atari
The Nintendo Entertainment System. Is it the platonic ideal of an 8-bit video game system? Well, only because it’s so prominent and successful– it’s actually...
