@amuletofyendor Fantastic! Inspiring me to give a prod at mine again.

[Robert Liesenfeld @AK6L]

Finally working version of Conway's Game of Life in durexforth on the C64. Unfortunately, it's unbearably slow.

@amuletofyendor I didn’t return to it after that post, I’d honestly sort of forgotten about it 🙂 I strongly suspect the neighbor lookup function needs to be done in assembly for it to be fast. How about you, did you give it a go?

[Robert Liesenfeld @AK6L]

@K9SWX That was my first transmit-capable radio too! I was excited about LEO sats and the dual VFO seemed perfect.

@particlesbbs Never mind, apparently it’s all over https://t.co/E5pa7kRioh and I’m just a dumb-dumb. 😁

[Robert Liesenfeld @AK6L]

@particlesbbs I miss, or all things, PC World magazine, which doesn’t appear to have been archived anywhere. I had a subscription for years, like 1992 to 96.

@scott_r_harris Just roll it over a few times, I’m sure it’ll be fine… as long as no one ever plugs a toaster into that circuit…

[Robert Liesenfeld @AK6L]

@TubeTimeUS Could it be MIDI packets?

[Robert Liesenfeld @AK6L]

@2111brainjar @ChartreuseK Favorite book of its kind, hands down. I loved reading this every time I visited my grandparents as a kid. Hugely influential. The art is fantastic too.

@alangarf I’m American so I think I’m required to encourage you to install the largest motor possible… 😁

And is this “emotionally fulfilling side project you said you’d finish by new years” in the room with us right now?

[Robert Liesenfeld @AK6L]

This is really cool!

Finally released: The GB Interceptor.

An open source rp2040-based adapter that goes between your (unmodified) Game Boy and the game cartridge to record or stream your gameplay via USB.

@K0FFY_Radio @w8lid I just fought off a bout of something, wasn’t fun but at least it was over quickly. Hope you recover as rapidly, @w8lid , I want to see your next industrial maintenance horror show! 😁

[Robert Liesenfeld @AK6L]

@4jawjan If it’s sketchy but it works, it’s not sketchy 😁

[Robert Liesenfeld @AK6L]

Lol, the product photo for this TI 99/4A.

@alangarf Very nice, what is that, over four thousand miles per watt? And on 10m no less!

[Robert Liesenfeld @AK6L]

@atomicthumbs @ChartreuseK I always thought that was a clever design but it also seemed flimsy. Probably frustrating to use at anything but egregious acceleration too.

[Robert Liesenfeld @AK6L]

@AA7EE Wow he makes beautiful boards! Thanks for the link, I must have missed this blog post the first time around.

[Robert Liesenfeld @AK6L]

KiCad users: has anyone done single-sided board layouts intended for Manhattan construction? Thinking I can just assign possibly-inappropriate surface mount footprints, or custom ones obviously, but wondering if anyone has other tips.

[Robert Liesenfeld @AK6L]

@imabug @AA7EE You should check out @alangarf’s tweets, he’s built a whole transceiver up from CNC milled boards. It looks like a great method but the spindle on my mill isn’t really fast enough for the drilling, hence my focus on surface mount, or Limerick/Muppet construction.

[Robert Liesenfeld @AK6L]

@N1FIY Thanks Brian, I’ll post here how it turns out!
