HeyMeco··on Proxmox Virtual Environment now available for 64-bit ARM (ARM64)
Much anticipated and finally available. I guess thank you Nvidia and regular installation on top of Debian Trixie works too so we should see support for SBCs and similar soon even though that would never be officially supported by them
HeyMeco··on Show HN: Modern Serial Console for macOS based on libghostty written in Swift
This is the result of me being not happy with cli based serial consoles like tio, screen etc. When I debug many SBCs with different baud rates I just want a simple modern interface with a drop down menu for baudrate (accepts custom higher ones too). There is already a MacOS app that comes close to this but costs $39 and doesn’t have a modern terminal like ghostty behind it. This is free, will continue to improve and open source.
HeyMeco··on Windows on Arm developer preview Nvidia driver works with regular GPUs
According to the dev who shared the screenshot of his RTX4060 ti running on a Radxa Orion O6 (Arm SystemReady) board they only needed to add the PCIe ID to the driver .inf file and it started to work.

The developer preview is intended for RTX Spark

HeyMeco··on MecoScribe: FOSS Local Audio Transcription for macOS with Speaker Detection
Yet another local transcription tool but this uses Parakeet V3 (with FluidAudio / Apple CoreML under the hood) instead of Whispr and allows for easy diarization (speaker detection) and quality control of the result through an HTML interface.

This tool is a result of me realising there are no real options for interview transcriptions with speaker detection that can be used in an university study evaluation context where you do not upload the data into a someone’s else’s cloud with questionable privacy policies.

Feature summary:

- Diarized transcription — identifies speakers and assigns words to each speaker

- Plain-text output with timestamps and speaker labels

- Interactive HTML with: Color-coded speaker segments Word-level highlighting synced to playback - Click any word or segment to seek in the audio

- Rename speakers

- Built-in audio player (with playback speed selection)

HeyMeco··on Tell HN: Installing Cursor on iOS irreversibly changes your privacy settings
Yeah fell into the same trap. Super annoying

They’re independent

HeyMeco··on Neptune: Direct3D Virtualization for QEMU
Interesting takeaway:

"Was it faster than doing it solo? Probably yes, on the order of 3–5× for the work captured in these transcripts, with the speedup concentrated in:

Mass refactor / rename work (10× or more — Claude can rename a function and update 200 call sites in minutes). Code review breadth (subagent fan-out reads more files per hour than any human can). Performance analysis writeups (the “table of metrics + paragraph of prose” format is something Claude is genuinely good at and is tedious for humans)."

HeyMeco··on Plex's price hikes prove I was right to switch to Jellyfin
Jellyfin is so much ahead when it comes to hardware acceleration on different platforms that it is actually sad to see how Plex has not made any improvements in years
HeyMeco··on New IKEA Matter over Thread bulbs can be switched to Zigbee by powercycling 12x
So today I found out the cheapest E27 smart bulb that is 1500lm bright and >90cri is actually an Ikea Kajplats Matter over Thread bulb that costs 9.99€

And it has one trick up its sleeve:

▶ If you turn it off and on 12x times it switches to a zigbee mode so I was able to integrate it into my existing HomeAssistant setup even easier

HeyMeco··on Rescuing old printers with an in-browser Linux VM bridged to WebUSB over USB/IP
ML-1740 is supported by the driver available here: https://www.bchemnet.com/suldr/index.html Works on my arm64 sbc as a cups printer for another samsung printer
HeyMeco··on Arm AGI CPU

HeyMeco··on ARM AGI CPU: Specs and SKUs
They actually said it’s coming in 2027 and ARM-AGI-3 is marked as future https://xcancel.com/mecoscorner/status/2036510613350785418
HeyMeco··on ARM AGI CPU: Specs and SKUs
It really is a choice for Arm to use their 2023 based mobile X4 cores instead of their current C1 Ultras for this. Hopefully they step up quickly
HeyMeco··on ARM AGI CPU: Specs and SKUs
I wonder what the people at Ampere are thinking right now

This is my condensed version for the SBCwiki documentation focused on the key facts without all the unnecessary marketing around it
HeyMeco··on Fast regex search: indexing text for agent tools
Instant Grep 13ms vs 16.8s ripgrep seems very useful
HeyMeco··on Arduino Ventuno Q First Look: Benchmarks, Specs and Mainline Linux
What we knew so far about the Arduino Ventuno Q:

- CPU: Octa-core with 4x A78 and 4x A55 - GPU: Adreno A623 - NPU: 40 TOPS dense Int8 - Wifi 6 (2.4/5/6GHz) & 2.5GbE LAN - 3x MIPI cameras at once

What is new:

- GeekBench 6: On Par with QCS6490 used in Radxa Dragon Q6A which starts at $70

- 6x faster than Arduino Uno Q

- 1/2 the performance of IQ9 series (all big core)

- Supports AV1 decoding and H265 / H264 encoding

- Further elaborated in the article

HeyMeco··on GeekBench 6.6 adds Vulkan on Arm GPU benchmarking on Linux
In the past you had to run the benchmark via an x86 translation layer like Fex / Box64 to get the Vulkan GPU benchmark. This was not reliable and led to crashes on some platforms. Thankfully we can run it native now
HeyMeco··on A legit 4k 100% P3 Portable OLED Monitor for under 250€ Review
I stumbled upon the VChance SU13 (here the SU13TO for the touch enabled variant) which advertises 100% P3, 4K resolution and a maximum brightness of 500 nits and this AliExpress find got me intrigued.

In the review I take a deep dive into calibrating this monitor and figuring out if it can keep its promise (spoiler it can but you have to know how).

HeyMeco··on State of Embedded: Q4 2025 Overview
First of all thank you everybody for reading and commenting! I want to address some of the comments I got regarding the article:

- xyz vendor is not covered: For this there is a simple answer, I don't have the hardware so I can't make a fair judgement when reporting about it. I don't want to be another reporter of basic benchmark scores & 1080P Youtube playback but actually show off the hardware capabilties with the right software. Hopefully this will be possible with more in the future as this project grows

- This is only one sector of the space why don't you have micro controllers or x86: While I want to cover all aspects of the space I am not an embedded engineer. I started during covid with the goal to replace my X86 homelab server with an ARM one to save power and got deeper into the rabbit hole until I ended up maintaining some boards and doing some Debian/Ubuntu based bring ups in my freetime. This led to me wanting to have one place to share my findings along the way and document things that might leave one stranded in the world of Yocto/U-Boot/Linux Kernel/Device-Trees/etc. and I created sbcwiki.com, not only for me to share my findings but for others to contribute with simple markdown files to the GitHub repo too.

HeyMeco··on State of Embedded: Q4 2025 Overview
In this format I go deep down the Mailing lists, news articles and more to summarise what exciting hardware has been published and software has been merged into Linux. Also breaking down rumours and developer conferences about future SoC‘s. Hope you all find it useful!
