Woohoo! My DiyIrTower PCBs have arrived!
("Do-it-yourself infrared serial communication tower (compatible with LEGO IR serial tower)")

I created a GitHub project for the #Turbokit replica for the #Generalmusic #S2. It is not a project for the faint of heart, however, at it will require to modify the original boards of the #synth. It is still pretty much an ongoing project: https://github.com/DarwinNE/GEM_turbokit #openhardware #electronics #diy
Which case actually makes sense for a LilyGO T-Beam SUPREME in real field use?
I compared designs, materials, print costs, and durability (PLA vs nylon vs resin), plus SD-card access. Includes a side-by-side video (7' 49") comparison.

Next up a DIY hotplate soldering reflow station, where the hot bit is just a PCB with a big wibbly copper trace all across its surface - and where the power comes from a USB Type-C Power Delivery input negotiating up to a whopping 100W.

Then an upgrade to the PicoRAM Ultimate project, which now delivers a whopping 4kB of RAM for compatible vintage single-board computers. What RAM shortage?

Open Source Hardware is the most important for humanity development. There was a project called OLPC https://en.wikipedia.org/wiki/One_Laptop_per_Child this concept should be merged with edge computing and ubiquitous computing to give a sort of platform. #opensourcehardware #openhardware
It is not only about social media corporations. The fact that large hardware and software companies control the very basic functioning of our digital world, like processors, and no one is caring about making technology independent, like chemistry IUPAC standards or ISO standards (or SI of physical units) is shocking. #openhardware
I am experimenting with a somewhat interactive list of #opensource tools for #openhardware #oshw https://beta.mid-size.org/ I appreciate feedback here or via mail
Coming back to OSHW atomic clocks. After thinking for a while. I think the cheapest option is to build a 87 Rb vapor cell coherent population trapping clock. I.e. one that shines a laser onto a vapor cell, which is modulated with half the hyperfine splitting.
The only special part needed would be the vapor cell, which can be had for 1k€ at Thorlabs (and others). Laser diodes are fairly easy to get, though need to be selected for modulation bandwidth.

What's an #OpenHardware sound level meter (for noise decibels)?
PineTime from Infinitime to WaspOS
I uploaded from WaspOS binary the bootloader and now I can't connect with my mobile anymore to the pinetime 🙄
I was once connected with my computer but disconnected, now I can't connect it anymore 🙄
I know it's not your OS, but do you have any trick @JF ?

Only three articles in today's #Hackster round-up, the last of the week.
First, a presentation from @fosdem by @olimex unveiling the Olimex-HoT, Home-of-Things - a low-cost single-board computer designed to serve as the heart of a smart home installation, using #OpenWRT to create a server that can run in just 128MB of RAM (and 128MB of storage) - now there's a fix for the AI-bubble's memory hunger!
We tested the waters with a no-logo faceplate… turns out people really like it 👀
It’s now a popular option for our RGB Word Clock Kit:

PicoIDE is an open source device that lets you use a microSD card reader with old-school computers instead of an IDE hard drive, CD-ROM, or floppy disk drive. There's also a Deluxe model with an OLED display and WiFi support. Crowdfunding now for $69 - $110. https://www.cnx-software.com/2026/02/02/picoide-an-open-source-hardware-ide-atapi-drive-emulator-for-vintage-computers/ #PicoIDE #OpenHardware #Crowdfunding
Finally, a 3D-printable exercise machine that turns your efforts into electricity for a phone or battery bank. Designed to be backpack-portable, too, so you can get a sweat on anywhere you like!

For the #sustainability crowd, a work-in-progress open-source solar micro-inverter - designed to be easily understand and reproduced locally for deployment in 230/240VAC regions.

Then a neat project to build a seven-segment clock out of nothing but a crystal and a bunch of discrete CMOS logic chips - schematic available if you want your own!
