I tried to grab one, but my Portable is being a bit finicky. I'll snap one when I figure out why it's not booting.

Since I didn't learn my lesson about my terrible design skills while trying to build a universal laptop power adapter, I recently ordered one of @Androda's Portable VGA adapters and thought, "I probably should cover this up before I damage it and short out something important". So I build a...

Appreciate it. I may need to look into PrusaSlicer (I use Cura just because it's what I learned on and I have my printer settings the way I like them). I used Stamping in MeshMixer to add the voltages, but I'm guessing PrusaSlicer would be a much easier, cleaner process. Here's the finished...

OK, I put together my own versions of these. One using the buck converter you specified, and two using this boost converter to get 16v and 24v versions: https://www.amazon.com/dp/B07BNHR4HW?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 I chose it because it matched the dimensions of the buck...

This is awesome. I've been exploring options for my vintage laptops and basically came to a similar solution to yours. I originally built a variable output device thinking one device for everything, but now I like the idea of USB-C with step-down / step up converters dedicated for each of the...

It does feel like the 24v to 20v may be too much of a gap. I think I may make a cable with the 12v trigger and a 24v booster inline. That will allow it to still be pretty discreet, but get me, hopefully, the stable 24v that will work best. I will still use interchangeable tips for the various...

OK, I went through a couple iterations and I think I got a good mix of sleekness and thermal handling. Waiting on my newest print to confirm, but with my earlier design, the buck/boost converter thermal protection would kick in and shut it down, which is not ideal when powering a laptop with no...

Ok, I got my new 3D printer and I need to do a bit of tweaking to get the print quality improved, but I was able to create a new box for the components and it’s a much better size. I’ll try to get the files posted up on Thingiverse with the full BoM when I have a bit of time. I also have a model...

My 3d printer is acting up, but I realized I have a plastic project box I never used and bought a panel mount USB-C port, cut some holes in the box, and put most of the stuff inside. The box is comically large for what I have inside, so I’ll address that when I make the printable box for...

I just had a co-worker give me his 512k (upgraded from 128k) and it had this on top. Here's a quick picture I took of the underside. I couldn't figure out what the floppy storage compartment was for, but thanks to this post I can confirm it does indeed fit 3.5" floppies very well.

OK, it's not an ideal solution, since it would be relatively easy to make a mistake and send too much power to the wrong laptop, but I was able to make a semi-universal laptop battery solution that works with most of my laptops. Basically, I start with a 20v USB-C trigger adapter (...

I've since upgraded the black AIO to a G4 from a Yikes machine, because that CPU is pin compatible with the G3 CPU in this machine. I figure if I was going to go away from stock, might as well make some more drastic changes. I have been thinking I may have missed an opportunity to match the...

Ah, in that case, I think our days of worrying about dust wrecking the fragile butterfly mechanisms in Apple keyboards are over. I've not heard anyone experiencing issues with dust rendering a keyboard unusable since the old butterfly keyboards that were phased out in 2019, I believe. The...

Yeah, that's fair. It does seem odd that you ordered online, chose a pickup location (so they knew how much tax was to be paid), paid an amount. Then, when you went to pick up they charged you just for the tax they could have charged you for with the order. I've never heard of that.

Interesting. I generally don't use my laptop when eating or drinking, but it sounds like you may have found a good solution.

Technically you would have had to claim it on your taxes if Apple had allowed you to pay a lower (or no) taxes when you picked it up. Unfortunately, what you tried to do, whether intentionally or not, was a small scale tax fraud. Probably good that Apple simply made sure you paid the correct...

I'm pretty sure the answer is to "don't do that". I believe the tolerances are so tight keyboard covers can cause issues. I've never done it so I can't say for or against, just the overwhelming message I've heard on reddit. What are you looking to get out of a keyboard cover?

Agreed that it's more about the effort and ability to create a longer lasting solution. My goal with the voltage adapter is that USBPD has voltage handshaking that these laptops aren't designed to do. Also, some of these power adapters have capabilities to restrict the amperage to not cause...

I just finished re-celling a few iBook G3 battery packs. While this will allow me to use them without being plugged in, and it certainly maximizes the portable nature of these machines, I had a couple thoughts: 1. I do have concerns about the safety of home built packs. I read up on it, bought...
