So pretty! My IP-KVM prototypes are here!
Bizarre seeing it IRL after staring at it in KiCad so long.

Really exciting work done by my colleague Daniel on a "water-in-salt", all-iron flow battery electrolyte. He's trying to repeat and build on some work from the University of Utah. If this works, it will be an even better approach than zinc-iodide electrolytes for low-cost, open-source flow batteries!

Doing cutouts without dimensioned drawings (apparently a luxury feature) was surprisingly not that bad, but still kinda bad.
Protocase Designer is also struggling to display text while running under wine, which is mostly funny, but some text does need to go on there at some point.
In contrast, #FreeCAD is excellent now! Post-1.0, it has everything I need to be productive, is more responsive than OnShape, and it hasn't crashed yet, which is a pleasant upgrade. The new measurement tool is also exceptionally smooth!

The next rev of the Deimos DAQ is almost a believable assembly, plus or minus a few cutouts and silkscreen labels!
Exciting news! Our datalogger, specially designed for our small wind turbine, is working! For the prototype version, we opted for a through-hole component design, making hand soldering a breeze.
Check out these pictures of the populated PCB in action!

New quest: build a powerful mini-ITX or similar tiny form factor PC to use with #MODaudio
I need a good class compliant USB audio interface to pair. Then, I'll have a portable system to do anything with!
The SW that runs on the #MODdwarf can run on any machine. I've been waiting years for these to be back in stock. Now, after spending a small fortune on other digital equipment, I'm debating selling it all.

Companies often claim their proprietary technology "democratized" something. Technology cannot be democratic if regular people lack permission to see and edit copies of the source files.
#FreeSoftware and #OpenSourceHardware are to technology what democracy is to government.
So I can't find a single dang component to get raw TMDS signals into my MCU and I don't want to get decoded signals because I should (my users should) be able to hack on the decoder, dag gummit.
Every TMDS chip I've looked at is doing way more than I want. And getting a generic comparator/amplifier with the necessary specs seems to be silly expensive?
Might try finding a cheap dumb LVDS receiver that has particularly generous tolerances?

Zukunftsfähige Elektronik ist reparierbar. Um das Problem mit den Ersatzteilen zu lösen, gibt es eine praktische Möglichkeit:
#opensourcehardware!
Man veröffentlicht die Baupläne, sodass die Kundschaft Ersatzteile im 3D-Druck selbst herstellen können.
#teufelmynd macht es schonmal vor!
c't MagazinSeite 2: Baupläne veröffentlichtDer Lautsprecherhersteller Teufel hat die Baupläne für einen Lautsprecher unter eine Open-Source-Lizenz gestellt. Wir sprechen über Motivation und Hindernisse.
My speaker manufacturer of choice, Teufel, just released an Open Source Hardware speaker. Now do it with the apps, please!
teufel.deMYND | TeufelMYND ab 229,99 € (22.07.2025): Leistungsstarker Bluetooth-Speaker bei der die effiziente Verwendung von Materialien, Langlebigkeit, recycelte Werkstoffe sowie erstklassiger Sound im Fokus der Entwicklung standen. Jetzt entdecken
Open Source Hardware. In diesem Fall von Teufel.
Das ist ein Ansatz, den ich komplett unterstütze.
Hier gibts ein wirklich interessantes Interview mit den Entwicklern:

I think the #ItxLlama is an interesting project.
- Shure it's not what I'm looking into but for those that want to rock an #AGP Graphics Card this is propably the #ITX #Maindoard to go with!

Given that I want to target i486 with @OS1337 but don't want to deal with obsolete hardware that is dying of old age, I think it's more fitting to consider a sort-of mainboard to shove some 486SX-SOM with PC/104-Plus on and have the few necessities hooked up to it. Maybe even put it inside a THINN #Pizzabox-style #case?
It would also make a new "bridge" machine to interface old PCI & ISA hardware and allow connecting i.e. a #QuadFlop and roll with that...

Thoughts, @rasteri @polpo @TechTangents @lazygamereviews @foone ??
I finally decided to break out of Bambu’s increasingly-closed walled garden.
I’ve had the Bambu X1C for a couple of years already, and it is a really, really great 3D printer. There’s no question whatsoever that Bambu has transformed the 3D printing space for consumers, and has done so while also creating some very high-quality premium hardware.
I’ve been meaning to write about the various mods I’ve made over time, but at this point it’s a bit far down the line to go into each one in detail 
- riser with LED strip, remote controlled via a Raspberry Pi Pico with a simple MicroPython HTTP-to-RF API that can dim the strip
- IKEA SKADIS mounted on the side with tools
- boxes to hold desiccant beads in the AMS, and a hygrometer
- after-market high flow nozzle (obviously)
- Garolite plate
- third party nozzle wiper
- etc etc
The printer has been very reliable, and straightforward to maintain as well.
So why hack it? Well… I own it, I think it can be made better, and… because.
When the X1Plus Expander launched on Crowd Supply I went ahead and backed the project, as I was interested in ways I could potentially add extra sensors and a better camera; as well as finally being able to connect over a LAN socket rather than having to be on wifi (the studio network can be a bit flaky from time to time).
The X1Plus Expander depends on third-party firmware (X1Plus), which requires the printer itself to be jailbroken / rooted.
Long story short, I’ve finally done that.
I was extremely impressed with how smooth and clear the project contributors have made the process. I went through the official process with Bambu to switch my printer into the unsupported third party program, downgraded to a rootable version of the firmware, rooted it, then ran through the remote install process (via wifi from my Framework) to install the firmware. I’d already printed the case for the X1Plus Expander. Then it was simply a case of following the exciting and dramatic installation video.
I now have VNC access to drive the controls on the printer’s touchscreen remotely; SSH access; the ability to network mount storage; etc etc. Lots of options to explore here. I was even able to upgrade the firmware of components like the AMS from within the third party X1Plus firmware.
You’ll also spot the OpenSpool sitting off to the side in the image above. That’s another third-party addon that I’ve barely started to use, but it extends the ability for the printer to recognise RFID-tagged spools from Bambu themselves, to having it recognise “any” spool that I happen to tag and configure.
All of this is background tinkering and admin… apart from the case for the X1Plus Expander, I’ve not been using the printer itself quite so much lately, due to travels.
Open source (and open source hardware!) FTW!
