All parts of the calculator body are printed from wooden PLA, all boards and blocks are soldered. What remains to be written is the firmware #riscv #ch32v003 including the display drivers (along with software backlight adjustment) and the keyboard driver, based halfway through @RueNahcMohr 's ideas.

Anyway, the fun part begins
Linus Åkessons new project is absolutely brilliant!
He's using the #RaspberryPi #pico 2 - in #RISCV mode no less - to create a VGA demo with generated graphics, PWM generated soundtrack and everything.
Check the video. And if you like it, there's a lot of detail on how he does it in the post.

@jbqueru like maybe the performance complexity somehow doesn't belong to a reliable RISC core... maybe we should have coprocessors again, with some sensible interface?
@jbqueru in light of all these extensions getting mixed it kinda looks like the elemental RISC idea has somehow evaporated from there, right?
I'm really confused by the world of #RISCV, it looks like the instruction set keeps changing and it's hard to know which machine supports which instruction set.
To put it simply: #Ubuntu is dropping support for RVA20, presumably to move to RVA22 instead. The problem is, the only RVA22 board I can seem to find (Milk-V Jupiter) isn't supported by Ubuntu.
The #EclipseFdn is hiring an HW Verification Engineer for its OpenHW Foundation. Working as a member of the Eclipse Research Team, the candidate will work to verify industrial-grade #opensource IPs based on #RISCV.

#wennIchZeitHätte würde ich ja gerne mal nen Haufen recht minimale #riscv cores 2-3 Dimensional anordnen & auf die Kanten schnelle Dual Port RAM packen ... In der Praxis vermutlich ne 2-D FPGA Matrix in die das sinnvoll rein synthetisiert ist. Also so ein bischen wie die #transputer... Ohne konkretes Ziel einfach um dann den Design Space zu erforschen.... Ok doch ein Design Ziel wäre das sich Software dafür aus ner dependently typed Sprache sinnvoll erzeugen lässt :) ... Wenn ich Zeit hätte.
Yay, finally all the pieces have come together and I have finally been able to compile Qt 6.9 and @kde Plasma development version (what is to be released as 6.4 in June) for my @bananapi BPI-F3, a RISC-V single-board (mini) computer. Plasma does start and run, but looks like QML/QtQuick applications (which includes the desktop itself) have rendering problems 
Qt Widget apps render/run just fine. Now to figure out where the problem is…
RISC-V as a #demoscene platform is becoming reality.
Here is Kaleidoscopico, a demo running on #raspberrypi Pico 2, presented at Revision Party last weekend.

I have the most important part of my RISC-V emulator done: I’ve picked a silly but apt name.
Speaking of #RISCV; watch this! https://www.youtube.com/watch?v=KhhLoVBpg48 A demo for the #raspberrypi #pico2 -- all video and sound generation is being done on the chip! #demoscene

Ethereum co-founder Vitalik Buterin has proposed replacing the Ethereum Virtual Machine with RISC-V, an open-source instruction set architecture, as the new foundation for Ethereum smart contracts.
