Was about to post the same thing. My favorite quote β€œThe algorithm doesn’t care what you complain about. It cares what you watch.” He hits the nail on the head with this one… I’ll see myself out.

Pantone FTW 😁. Also might not be the color of the pigment could be translucency… or both…

Ah yeah I’ve had good luck with printing pad masks for larger pads but for tiny ones like this - the only thing I’ve gotten to work somewhat reliably is applying the solder mask to the whole board and then using a mask removal bit to carve it away. Took a lot fine tuning but came out ok.

I’m using a regular β€œopal” colored UV solder mask - pressed as thin as possible between a flat acrylic block and a layer of acetate before curing - and yeah you’ll notice the board design is a bit… creative to ensure this one is just one-sided so I didn’t have to deal with via rivets.

One other thought - is the plastic brittle? Or was it just seriously beat up? If it’s brittle I’d say it’s probably not worth trying to weld or bond it back together. If it’s not then it’s a totally valid direction to take and would ultimately be less work.

Oh noooo! Is the CRT still firmly mounted to the rear case? Good news is that the front is really just cosmetic so you don’t have to worry about using structural plastics if you do decide to redo it.

Modeling that front face would be a not-insignificant but totally worthwhile project. 🀘

CNCing my own PCBs in hard mode. Technically functional but emotionally concerning. Send help.

Totally this. Too much acetone can make a larger area warp, remove texture, etc. repair looks great!

Thanks for the share! And yeah def post pics. I’m also curious to know how brittle it is. If it’s not there are a few good options.

Interesting. You let riffraff like me into these things?

THE HALIKAN LIVES

youtu.be/3_XdQwZSrag

The Chaplet Halikan LA-30 is an interesting 80s laptop on its own but this one busting into 1000 pieces & being restored by PolyMatt takes it to another level. Let's dive into using the PC itself, its odd quirks, and its small but fascinating spot in history!

That’s actually hilarious. Now, if it’s real and not a funny joke from the developers, it’s still hilarious but in a laughing-at-you way and not a laughing-with-you way…

Same experience. It’s an 80s term but it was definitely used in the industry. But it actually WASN’T limited to 3.5” inch format…

Such an amazing product from yyzkevin.com. Can’t wait to try it on my ThinkPad 701C collection. If you’ve got a beloved vintage laptop this thing is a Swiss Army knife of gloriousness…

And while it’s tempting to change things up, I’ve decided to stay the course and keep my release schedule and cadence and focus on making the videos even better β€” and there are some awesome videos to come!

Well everyone it’s been an EPIC year. I’ve released 4 long form videos, got written up in PC Gamer, Engadget, techradar, hackaday, broke 100k subscribers and had over 36 years of watch time from 1.8 million views.

And it’s all thanks to you. I’m incredibly grateful for your support. πŸ™
