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.
Introducing Robostral Navigate: 8B model achieving 76.6% on R2R-CE with just a single RGB camera. No depth sensors, LiDAR, or multiple cameras needed.
Putting iroh on a bare ESP32 to build a temperature-driven smart fan you can check on from anywhere.
The challenges around porting Linux to an old videogame console by Atari
Welcome to LTT Labs - your go-to destination for all things tech. Explore comprehensive test results, insightful commentary, and the latest analysis in hardware.
Starting summer 2026, in preparation for upcoming changes in European battery regulations coming into effect in mid-February 2027, selected Nintendo products in Europe will begin to be replaced on a rolling basis by revisions that contain a user-r
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...
Capacitor vendors don't want you to know this! Save money on capacitors by spending more on other components
We've seen the strong reaction from the community over the idea that we've stopped developing the Flipper Zero firmware. We want to address this and let you know that we've heard all your feedback and have decided to rethink our approach to maintaining the project and engaging with the community.
Adventures in programming, hardware, DSP, and chiptune
How we served GLM5.2 on AMD MI355X at 2626 tok/s/node and 213 tok/s single stream at over 2x lower cost than Blackwell.
Small personal devices are multiplying whether we build them or not. The real opening is the software that runs on them, and who gets to write it.
I’m starting a new build-in-public project: oomwoo, an open-source robot vacuum you build yourself. Raspberry Pi, ROS 2, 2D LiDAR, Home Assistant, 3D printed, local-first — and open from the first commit.
Isaac 1 is a mobile robot for the home — designed and assembled in San Francisco. Five colorways, private by design, and capable of far more than folding.
Equations governing dynamics and control of a multirotor UAV
Software is now a commodity thanks to Claude Code. So the next step is obviously hardware. I spent the last 6 months on building a hardware startup, which was fucking hard.
Tracing one vector-add kernel from nvcc all the way down to the warps that execute it.
We traded the physical boundaries of dedicated rooms for the convenience of our always-on digital lives -- but recently I've been building those walls back up.
Back in the late 1970’s and early 1980’s Sandia National Laboratory (in Albuquerque NM USA) began building the capacity to design, fab, and test IC’s at scale (packaging was handled by Fairchild and Allied Signal). Why would a National Laboratory need the capacity to do this? To provide components that were not…
When I started using computers, we had a Sinclair ZX Spectrum at home and a nano-reseau of Thomson MO5 s at elementary school. I distinctly remember how unpleasant it was to type with them. These must have been the worst keyboards I ever used [1] . Ever since, I have paid close attention to the keyboards I use. Here…
The Space Shuttle's five 1 general-purpose computers played a critical role in each flight: controlling the engines, monitoring thousands o...
Building a custom octocopter from scratch with an RL controller that sustains flight through motor failures. Follow the build log.
I built a 10-inch mini rack from aluminium extrusions and I had a lot of fun doing it. I want to share my build in this post.
Ignoring EFF’s warnings about the dangers and impossibility of implementing a new mandate for 3D print surveillance software, the California State Assembly has signed off on legislation to do just that. In the process, legislators amended the bill to make it even more confusing, while failing to address the risks to…
Hiking with Wallace, my 6" f/2.8 corrected dobsonian.
