Grinn ReneSOM-V2H is a tiny LGA SoM based on Renesas RZ/V2H processor for vision AI applications

Polish embedded systems company Grinn has recently introduced ReneSOM-V2H, a tiny vision AI SoM built around the Renesas RZ/V2H vision AI processor. Measuring just 42.6 x 37 mm, Grinn claims it is the world’s smallest module based on this specific Renesas MPU, and targets space-constrained Edge AI applications such as smart cameras, robotics, and industrial automation. The RZ/V2H SoC features a heterogeneous architecture with 4x Cortex-A55 cores, 2x Cortex-R8 cores, and 1x Cortex-M33 core, along with a DRP-AI3 accelerator with up to 8 TOPS. It supports LPDDR4 memory and eMMC storage, along with various connectivity options, including PCIe Gen3 (4-lane),...

Using a Solid-State Elastocaloric Cooler to Freeze Water

Elastocaloric materials are a class of materials that exhibit a big change in temperature when exposed to mechanical stress. This could potentially make them useful as solid-state replacement for both vapor-compression refrigeration systems and Peltier coolers.

So far one issue has been that reaching freezing temperatures was impossible, but a recently demonstrated solution (online PDF via IEEE Spectrum) using NiTi-based shape-memory alloys addressed that issue with a final temperature of -12°C achieved within 15 minutes from room temperature.

In the paper by [Guoan Zhou] et al. the cascade cooler is described, with eight...

Running Video Through A Guitar Effects Pedal

https://invidious.privacyredirect.com/watch?v=WG0KVxWWH18

Guitar pedals are designed to take in a sound signal, do fun stuff to it, and then spit it out to your amplifier where it hopefully impresses other people. However, [Liam Taylor] decided to see what would happen if you fed video through a guitar pedal instead. 

The device under test is a Boss ME-50 multi-effects unit. It’s capable of serving up a wide range of effects, from delay to chorus to reverb, along with compression and distortion and a smattering of others. [Liam] hooked up the composite video output from an old Sony camcorder from the 2000s to a 3.5...

Checking out the actual AMD Ryzen SoC used on CHUWI CoreBook Air Plus 16 laptop

I’ve just completed the review of the CHUWI CoreBook Air Plus 16, a laptop based on an AMD Ryzen 5 6600H SoC. All software testing on Windows 11 Pro and Ubuntu 25.10 confirmed that the laptop was based on an AMD Ryzen 5 6600H SoC, but I was asked to confirm that the actual CPU on the motherboard was indeed the advertised chip, for reasons I’ll explain below. Let’s do that right now. I had already done a teardown of the laptop, but since the AMD Ryzen processor was covered by copper pipes for cooling, I could not read the...

Trying a Vibe-Coded Operating System

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

If you were to read the README of the Vib-OS project on GitHub, you’d see it advertised as a Unix-like OS that was written from scratch, runs on ARM64 and x86_64, and comes with a full GUI, networking and even full Doom game support. Unfortunately, what you are seeing there isn’t the beginnings of a new promising OS that might go toe to toe with the likes of Linux or Haiku, but rather a vibe-coded confabulation. Trying to actually use the OS as [tirimid] recently did sends you down a vibe-coded rabbit hole of broken code, more bugs than you can...

Raspberry Pi CM5 industrial computer features RS485/RS232/CAN Bus/DIO interfaces, dual Ethernet, optional 4G/5G cellular module

Waveshare IPCBOX-CM5 is an industrial-grade mini computer built around the Raspberry Pi CM5, featuring RS485, RS232, CAN Bus, and DI/DO terminal blocks, dual Ethernet, an M.2 socket for NVMe SSDs or AI accelerators, and a wide 7V to 36V DC power input. The system is compatible with all CM5 variants and integrates GbE and 2.5GbE ports, a 4K-capable HDMI video output, multiple USB 3.2/2.0 ports, and an M.2 B-Key slot plus a Nano-SIM card slot for 4G LTE/5G cellular modules. Other features include microSD card support for Raspberry Pi CM5 Lite models, a PWM fan header, a buzzer, an audio...

Embossing Precision Ball Joints for a Micromanipulator

https://invidious.privacyredirect.com/watch?v=NM2KXvRGmpg

[Diffraction Limited] has been working on a largely 3D-printed micropositioner for some time now, and previously reached a resolution of about 50 nanometers. There was still room for improvement, though, and his latest iteration improves the linkage arms by embossing tiny ball joints into them.

The micro-manipulator, which we’ve covered before, uses three sets of parallel rod linkages to move a platform. Each end of each rod rotates on a ball joint. In the previous iteration, the parallel rods were made out of hollow brass tubing with internal chamfers on the ends. The small area of contact between the ball and...

NanoPi NEO3 Plus – A tiny Rockchip RK3528A headless SBC with Gigabit Ethernet, USB 3.0 port, GPIO header

FriendlyELEC NanoPi NEO3 Plus is an ultra-compact headless SBC powered by a Rockchip RK3528A SoC paired with 1GB RAM, whose main interfaces are a Gigabit Ethernet jack, a USB 3.2 port, and a 26-pin GPIO header. I can still remember using its predecessor, the NanoPi NEO3, based on a Rockchip RK3328, which I reviewed with Armbian in 2020. The new model is similar, with a quad-core Cortex-A53 SoC but clocked at 2.0 GHz instead of 1.5 GHz, and offered with a black metal case instead of a white plastic case. The OS can still be booted from a microSD card,...
