Mentra Brings Open Smart Glasses OS With Cross-Compat

There are a few very different pathways to building a product, and we gotta applaud the developers taking care to take the open-source path. Today’s highlight is [Mentra], who is releasing an open-source smart glasses OS for their own and others’ devices, letting you develop your smart glasses ideas just once, a single codebase applicable for multiple models.

Currently, the compatibility list covers four models, two of them Mentra’s (Live and Mach 1), one from Vuzix (Z100), and one from Even Realities (G1) — some display-only, and some recording-only. The app store already has a few apps that cover the basics,...

Condensing Diesel Heater Hack Is Dripping With Efficiency

https://invidious.privacyredirect.com/watch?v=rjgOsJmnqYc

Not a huge percentage of our readers probably get their heat from diesel fuel, but it’s not uncommon in remote areas where other fuels are hard to come-by. If you’re in one of those areas, this latest hack from [Hangin with the Hursts] could save you some change, or keep you  ̶2̶0̶%̶ ̶c̶o̶o̶l̶e̶r̶  25% warmer on the same fuel burn.

It’s bog simple: he takes his off-the-shelf hydronic diesel heater, which is already 71% efficient according to a previous test, and hooks its exhaust to a heat exchanger. Now, you don’t want to restrict the exhaust on one of these units,...

Get Statistical About Your Pet With This Cat Tracking Dashboard

Cats can be wonderful companions, but they can also be aloof and boring to hang out with. If you want to get a little more out of the relationship, consider obsessively tracking your cat’s basic statistics with this display from [Matthew Sylvester].

The build is based around the Seeedstudio ReTerminal E1001/E1002 devices—basically an e-paper display with a programmable ESP32-S3 built right in. It’s upon this display that you will see all kinds of feline statistics being logged and graphed. The data itself comes from smart litterboxes, with [Matthew] figuring out how to grab data on weight and litterbox usage via APIs....

Jetson Thor industrial PC pairs 25GbE networking with optional GMSL2 camera support

FORECR has introduced the DSBOX-THRMAX, an industrial box PC based on NVIDIA’s Jetson Thor (T5000) module, targeting robotics, autonomous machines, and edge deployments that require high compute density, real-time processing, and multi-sensor support. The platform is based on the NVIDIA Jetson T5000 module, which is specified to deliver up to 2070 TFLOPS of AI performance […]

User Serviceable Parts

Al and I were talking on the podcast about the Home Assistant home automation hub software. In particular, about how devilishly well designed it is for extensibility. It’s designed to be added on to, and that makes all of the difference.
That doesn’t mean that it’s trivial to add your own wacky control or sensor elements to the system, but that it’s relatively straightforward, and that it accommodates you. If your use case isn’t already covered, there is probably good documentation available to help guide you in the right direction, and that’s all a hacker really needs. As evidence for why...

CIX releases P1 CPU TRM and developer guides for GPU, AI accelerator, OS and firmware/BIOS

CIX has finally released the technical reference manual (TRM) for the P1 (CD8180/CD8160) Arm Cortex-A720/A520 SoC, along with developer guides for the GPU (Arm Immortalis G720 and NVIDIA/AMD discrete graphics cards), the AI accelerator, as well as OS (Android, Linux, and Windows) and firmware (BIOS) installation and development. A slow (but steady?) progress There was a lot of excitement when the Radxa Orion O6 mini-ITX motherboard was introduced in December 2024, as we were told the CIX P1 12-core Armv9 processor would offer performance similar to Apple M1 SoC and Qualcomm 8cx Gen3 platform, at an affordable price ($199 and...

CM0 - a new Raspberry Pi you can't buy

CM0 - a new Raspberry Pi you can't buy

This little postage stamp is actually a full Raspberry Pi Zero 2, complete with eMMC storage and WiFi.

But you can't get one. Well, not unless you buy the CM0NANO development board from EDAtec, or you live in China.

This little guy doesn't have an HDMI port, Ethernet, or even USB. It's a special version of the 'Compute Module' line of boards. Little Raspberry Pi 'System on Modules' (SoMs), they're called.

Compute Modules are entire Linux computers about the size of a regular...

Diptyx E-Reader – An open-source, ESP32-powered, dual-screen e-book reader (Crowdfunding)

There are plenty of e-book readers on the market, but the Diptyx E-Reader feels more like a proper book since it features two e-paper displays that can be folded or opened thanks to a custom-made plastic enclosure. While it’s powered by an ESP32-S3 wireless module with a PCB antenna, both WiFi and Bluetooth are disabled in the firmware, and instead, users can load EPUB files through the reader’s USB Type-C port. The combination of an automatic standby mode (using deep sleep) and e-ink displays enables the dual-screen device to run for weeks on a single charge. Two buttons are used...

Renesas RA6W1/RA6W2 Cortex-M33 wireless MCUs offer dual-band Wi-Fi 6, BLE, Matter, 15-year availability

Renesas has added the RA6W1 (Wi-Fi 6) and the RA6W2 (Wi-Fi 6 + BLE) MCUs to its high-performance RA6 family, adding dual-band Wi-Fi 6 and Bluetooth LE, as well as Matter connectivity to the series. Both models feature a 160 MHz Arm Cortex-M33 core, dual-band Wi-Fi 6 with WPA3 security, on-chip PA/LNA/RF switch, and a full TCP/IP stack for fast connectivity. They integrate up to 704 KB SRAM, 256 KB ROM, and support eMMC/SD, O-QSPI, and QSPI for external flash and/or PSRAM. The series also includes generic peripherals like SPI, I²C, I²S/PDM, SDIO, 12-bit ADCs, PWM timers, and up to...

Иногда компьютеры ошибаются. Воспроизводим тот самый баг на $475 000 000

Приветствую всех!

Знаю: тема багов, которые изменили мир, избита уже настолько, что на ней не осталось живого места. Но сейчас мы не будем просто говорить о самых выдающихся таких случаях. Сейчас мы затронем лишь один из них: ту самую ошибку в процессоре Pentium. И не просто поговорим обо всём этом, а ещё и продемонстрируем её на реальной машине.

Итак, сегодня мы разберёмся, что же это был за баг в данном теперь уже ретро-процессоре. Узнаем, как он проявлялся, как его воспроизвести и, конечно же, увидим вживую, как всё это работало.
