There have been some past rumblings on the internet about a capacitor being installed backwards in Apple’s Macintosh LC III . The LC III was a “pizza box” Mac model produced from early 1993 to early 1994, mainly targeted at the education market. It also manifested as various consumer Performa models: the 450, 460…
A guide to the operating principles, techniques and technology in lidar systems for self driving cars.
I was studying the silicon die of the Pentium processor and noticed some puzzling structures where signal lines were connected to the silico...
A 192-channel phased array microphone, with FPGA data acquisition and beamforming/visualization on the GPU. Phased arrays allow for applications not possible with traditional directional microphones, as the directionality can be changed instantly, after the recording is made, or even be focused at hundreds of…
A magazine on a floppy from 1986.
AlphaQubit is an AI-based decoder that identifies quantum computing errors with state-of-the-art accuracy.
The other day I saw the launch of Apple Vision Pro, the whole thing was very interesting, but one thing that caught my attention was the finger input. It seems very intuitive, by using the finger pinching as sort of like a cursor or mouse input. I figured I want to try it out, so I took it upon myself to create it.
Llama 3.1 405B on Cerebras is by far the fastest frontier model in the world – 12x faster than GPT-4o and 18x faster than Claude 3.5 Sonnet.

Today marks two years since I first set up an e-ink display in my mom’s apartment to help her live on her own with amnesia.
DeepComputing is excited to announce the launch of an exclusive early access program for the DC-ROMA RISC-V Mainboard, specifically designed for industry and business customers. This limited-edition initiative gives early adopters hands-on experience with premium, modular RISC-V development hardware, while their…
Last summer I got into cycling. I've long been a standing desk-er, and going out for long zone 2 rides and wondering what to think about made me wonder: could I work at a desk while I cycle?
I tried everything but couldn’t turn this Raspberry Pi 5 into the World’s Fastest Pi 5. Unfortunately, we can’t quite claim that title.
I had to pause some of my work getting a current-gen AMD graphics card running on the Pi 5 and testing a 192-core AmpereOne server to quickly post on the M4's efficiency. I expected M4 to be better than M1/M2 (I haven't personally tested M3), and I hoped it would at least match the previous total-system-power…
How we bypassed Apple's regulatory restrictions, built a Faraday cage and enabled georestricted features on the Airpods Pro 2 for our grandparents.

Our first generalist policy, π0, a prototype model that combines large-scale multi-task and multi-robot data collection with a new network architecture to enable the most capable and dexterous generalist robot policy to date.
Have you ever wished for a 500 Hz, millimeter-precise linear position sensing system? Well you're in luck --- all you need is some circuit board, a basic microcontroller, and a wee bit of maths!
Learn how WSPR (weak signal propagation reporter) technology is a fascinating facet of the Ham radio hobby in this easy-to-follow article.
A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually…

While everyone was waiting on news for the successor of the Nintendo Switch, Nintendo released the Alarmo. A small plastic alarm clock that ...
Apple today unveiled the new MacBook Pro, powered by the M4 family of chips: M4, M4 Pro, and M4 Max.
TLDR: If your job is to write code all day or stare at Excel spreadsheets, buy an 8K TV instead of a multi-monitor setup. You can even use the same TV for 4K 120 Hz gaming or watching movies as a bonus!
Apple today unveiled the all-new Mac mini powered by the M4 and new M4 Pro chips, and redesigned around Apple silicon so it’s even smaller.
Apple today announced the new iMac, featuring the powerful M4 chip and Apple Intelligence, in its stunning, ultra-thin design.
