This is a real breakthrough at an unusual time! The Kramer-MC still boots from its ROM and can still write data to its screen RAM. And it does so via the originally intended DS8286 bus driver. This didn't always work because the system bus and internal data bus were still completely shorted. The previous owner didn't finish, even though the computer was prepared for CP/M.
It took a bit of courage to cut the eight data lines near the connector :D Now I think it's working as intended. The boot ROM is active first reset. A flip-flop is activated via pin 37 on the UA855D, which makes the ROM invisible at its /E pin. While the ROM is still active, the parallel RAM can still be written in parallel (shadowing). The data bus is protected by the DS8286. Implemented with a total of 3 TTL ICs (K555LA3, 74LS74, and 74LS138). Awesome.

Držák na kameru otestovaný a čeká na finální tisk a nalepení na helmu.
Nová powerbanka má zatím "jen" nástřel, čekám, až mi přijdou díly, abych si je mohl přeměřit a zakomponovat. Tentokrát jsem vybral 3,7V/4000mAh LiPo článek (14,8Wh) a 2A výstup, takže bych měl být schopný v případě upgradu uživit i žravější kameru, než 5V/500mA.
U téhle verze powerbanky chci víc dbát na voděodolnost a modularitu systému.

🎉 Oh joy, someone bought a DGX Spark and decided it's the perfect gadget for playing StarCraft II and "tinkering" with Darktable 😂. Because why not use a $10,000 supercomputer for running games from 20 years ago? 🚀👾

😆🤖 Murati's Thinking Machines releases a "groundbreaking" 975B parameter model, claiming you can "tinker" with it like a toddler with a toy! 🎉 Meanwhile, it struts around comparing itself to the likes of GPT and GLM as if it's the new Einstein of AI. 😂💡

My goal for 2026 is to manage my digital stuff more effectively on my own (self-hosting)! 😉

That’s why YunoHost is my current project—I’m researching it and narrowing down my options. 😁

I like and need to tinker with digital stuff every now and then—even if it sometimes causes stress and makes me tear my hair out. 😅

So far, @markus has taken care of managing my digital space, which works perfectly and without any issues. 👌

In the future, though, I want to get more involved myself again and learn a thing or two along the way, especially since I’ve been using Linux—specifically Mint (for work) and Arch (for gaming)—in my personal life for a few years now. 😊

Had a successful DIY Saturday—built a split-system air conditioner. It’s supposed to be a bit more effective because it eliminates the negative pressure in the room that otherwise draws warm air back in from outside.

So I did a silly thing ... Maybe it will work ...

My brain said: What if Tailnet device sharing but better

So I tried building something (currently very very bare prototype) that allows me to share subnet routers between Tailnets. In the end it was quite simple: Do manual route entries and like 2 subnet routers in a docker net. Will see if that works.

Now I must find a test subject :neocat_evil_3c:

25km on the #ebike this morning — first proper test of the second-hand motor and battery I fitted myself. Battery's only done ~35km all up on this charge and still pulling strong. Cheap parts, a bit of #tinkering, and a good #ride out of it. I'll take that. #cycling #DIY #BikeLife

Most students learn 3D printing from diagrams.
Ours experienced it.

Toothpaste + layered shapes = real understanding of additive manufacturing.

Simple idea. Powerful learning.

#HandsOnLearning #STEM #STEMLearning #wow3dlearning #tinkering #tinker #3dprinting #designthinking

What if you could teach 3D printing… using toothpaste?

Our Grade 8 students tried something super fun:
Layering toothpaste over black and white printed shapes to see how 3D objects are built with one layer at a time.

From flat to form, they experienced the magic of additive manufacturing with their own hands.

Learning by doing always wins.

Tak zatímco jsem obětoval jeden nafukovací balonek na ochranu elektroniky, dostal jsem prakticky magické soukromé oko bez deště 😄
Oproti loňsku jde o obrat, protože tehdy jsem dostal vždycky svůj osobní mrak na cestě do práce i z práce 😅
