TuxCon2025 is May 10-11 and you are welcome to join. This is free to participate Open Source Hardware and Software conference in Plovdiv, Bulgaria. This year we have guest lector from @seeedstudio Violet Su , the very first retro computer IMKO-1 will be present by Anton Orush https://olimex.wordpress.com/2025/04/16/tuxcon-2025-the-open-source-hardware-and-software-conference-in-plovdiv-is-on-may-10-11th/ #oshw #tuxcon #imko-1 #pravetz82 #retro #computer #free #event #foss
The frob is a reverse engineered #Apple 2 development board for the #Atari VCS 2600

Oh this looks like a very cool #oshw device, hadn't heard of it before

Superb to see the @DoESLiverpool community on a roll of @oshwassociation open hardware certifications 
The last three UK OSHWA certifications are from three different members of the community:
https://certification.oshwa.org/uk000072 was Spoonbot by #STEAMEngineers @huffeec and @Snoof
https://certification.oshwa.org/uk000073 is @MCQN_Ltd's My Bike's Got LED
And https://certification.oshwa.org/uk000074 is the Mathpad by Magne Lauritzen
Ashtf's #OSHW EinkPDA has some really nice looking updates, glad to see this project continue to progress

Today some more OSHW work: an unreasonably large Raspberry Pi hat.
This is part of the Open Weed Locator project, which does open-source/low-cost green-on-brown and green-on-green weed detection, suitable for retrofit to existing broadacre spray systems. It allows the Pi to control 16x 2A outputs driving solenoids (or anything else) and it's designed to be robust, self-documenting and repairable in the field.
Still a few checks to do but looking good for an initial prototype order over the weekend.

OK, so we've got a pretty robust #OSHW ecosystem around producing #3D printers...
And there's lots of #grbl pen plotters and such...
But is there anybody working on open source paper printers? I guess I'm not terribly concerned about what technology a given example implements (i.e. direct impact, laser/toner, inkjet, thermal, whatever) but I'm mostly curious whether the space for this is just so saturated for so long with commodity printers that nobody's exploring this. I'm not even certain what problem might be solved by such a thing.
I guess on some level, the printed page is likely to *always* be the most-robust medium for #archives of knowledge and information, and also one of the most accessible, generally. Being able to produce printed pages from digital sources is so important that I guess I'm skeeved out that this seems to be mostly limited to appliances produced without the same benefits we see in OSHW.
openheart is an #opensource and cheap multi-mod powered by a #raspberrypi pico for the #Sega #Genesis #MegaDrive that adds region switching, TMSS bypass and overclocking.
There's something of a @DoESLiverpool takeover of the @oshwassociation Show and Tell this month - I'm going to be on talking about @MCQN_Ltd's My Bike's Got LED boards and @huffeec and @Snoof will be repping their company STEAM Engineers too!
Tune in at 5pm GMT https://www.youtube.com/watch?v=LwPf12toLq4
Catching up on the @oshwassociation show and tell sessions to remind myself of the format before I'm on it on Thursday, and it was lovely to hear about @ivor's IvorTRK
Just released a preview video for my current project: a DIY open hardware TFT display mod for the classic Game Boy (DMG01). I built it using the new RP2350B, so the release will have to wait until Raspberry Pi officially launches the controller chip. I’ll post an update when the project is ready for the public.

The Open Source Hardware Linux SOM module iMX8MP-SOM-4GB now have Armbian / Debian12 Linux image https://olimex.wordpress.com/2025/03/13/the-open-source-hardware-imx8mp-som-now-have-armbian-based-linux-image/ #imx8mp #armbian #linux #oshw
Keeping with the 15khz theme. Here’s a tester. I made a few years ago. Just plug it in, power the monitor up, and press the little button. Within 3 seconds you’ll know if the monitor is compatible.
And a fully free design as well: https://github.com/planeturban/15khzvgatester
As initially announced, this project is of course 100% #OpenHardware 
and is licensed under the terms of the CERN-OHL-S v2 or later.
The #KiCAD source files for the "relays array" board are already available from https://github.com/a-wai/amp-switcher , the rest will follow as soon as I implement it

AmigaBlueKick - do you want to have a kickstart ROM selector in your #Commodore #Amiga 500/600/2000, but don't want to drill holes in your case for a switch? Check out this Bluetooth enabled one.
The Flow Battery Research Collective (FBRC) are building an open source battery. Technology writer Koen Vervloesem did a nice write-up about their #FOSDEM talk in the Energy devroom. FBRC works on redox flow batteries which are better suited for long-term, stationary storage and less hazardous than Li-ion batteries. FBRC plan to democratize flow battery technology by developing an open source flow battery, starting with a development kit.
A good way for people to keep control is to go open source. Think about it for your next creation.
