Assembling the rest of the axis sensor circuits for my joystick project today. Tiny surface mount components call for solder paste, a heat plate, and dark drum and bass

My head hurts.
I just realized that you can build filters for radio out of knotted wire. And you can directionally and phase-tune elements that way too. Like... part of me knew that, had seen that when building radios before - that you don't actually need a core material (other than air or fr4 or whatever) for inductance and reactance to happen. That you can etch filters just by shaping copper in circuit boards - and you can also build complex capacitors with just multi-layer circuit boards. And like... yagi and j-pole and phased array and hoop antennas do work quite well.

But then I was playing with tying some rope, found a pretty knot and started thinking about chirality of knots tied in-place on multiple strands. And somehow ended up here. Thinking about uhf and microwave band tuning stuff, but built big enough for hf problems.

My mind it wanders. too boldly by far.

This project is moving from #theWorkshop to #theFoundry the deeper I get into it. :neofox_laugh_sweat:

Don't wanna jinx it yet, so all I'm gonna say is that the #CollapseOS #PocketViewer ROM writer is finally picking up steam. :neofox_owo:

Nothing like trying to build a machine monitor from scratch to make me appreciate #WozMon even more. I think I finally have a hex nibble parser (haven't tested it, yolo) and a byte parser, so parsing an address should be easy... right? Well, not if you've never written a parser in assembly before and want to avoid using the stack.
So, yeah #65cha02 is a bit stuck right now. Might put it on hold tbh, I want to have something ready for Árok this summer. Last time I said I'd have something running on the PocketViewer, so I'd better hold myself to that promise.

Ayy, after a lot of debugging, my ring buffer copying code for #mos6502 works!!!
I only made like 8 embarrassing mistakes in the process, but hey, #assembly is hard. And fun!
So, #65cha02 is back on track. Now to incorporate the ring buffer code into a machine monitor...

Found an assembler for #65cha02 written in Go that I can just embed directly. :neofox_owo:

...but now I have to modify the disassembler endpoint to produce the assembler's syntax :oh_no:

There is a combined dis/asm (+emul but not gonna use that) library as well (written in Go), maybe that's the way to go... but I like the simplicity of the other one... maybe I'll just fork the disassembler part? :flan_shrug:

#65cha02 is becoming usable in read-only mode. :eyes_fast:
Hex, disasm, mono, and gray views are Good Enough.
Assembly is tricky. I'll probably have to customize an existing one.
I think I can set up a closed beta Soon (TM).

#Pinecil stopped charging through USB-C and based on what I've read by others, it's a known hardware issue. Honestly the number of hardware issues with #Pine64 products is making me heavily reconsider ever buying from them again. :sadlinux:
I think the Pinecil is still under EU warranty, so I'll try getting it replaced, but maybe the hassle is not worth it and I should just buy something more reliable.
Sucks, because I like open and affordable hardware.

Great video by #BenEater on the #MOS6502 machine monitor.
I'm working on some low-level #PocketViewer stuff in #theFoundry , so I found it especially useful. Probably won't go to this level of optimization though, at least not for the first implementation.

Noob #reverseEngineering milestone: reversed an optimized memcmp and figured out that the decompilation in #Ghidra was wrong and that it's returning the result in ZF and then fixed the decompilation by editing the signature. UwU

I just opened my self hosted instance of #SearXNG to public access: search.falai.se.

"SearXNG is a free internet metasearch engine which aggregates results from more than 70 search services. Users are neither tracked nor profiled."

It's still experimental and not fully optimized (e.g. TLS grade is E), but perfectly functional. Listing on searx.space is on its way.

Feel free to use it!

Repurposing widely available hardware to do something it wasn't meant to do is extremely my jam. :tealheart: :permacomputing:

Weird #permacomputing / #lowTech display thought:
couldn't a DIY etch-a-sketch with stepper motors be a slow but possibly good enough display device?
It seems like multiple people have built it as a toy project.
It's kind of like e-ink, except much cheaper.

Is there a collection of "self hosted" #demoscene productions? Like, prods developed on the target device as much as possible, without heavy reliance on emulators.

This #eGPU Thinkpad setup is really neato. Slightly cursed, but also, damn, I could use this to get modern Blender running on my Thinkpad.
