The first Pentium processors Intel shipped used a single 5 Volt power supply and came in a "Socket 4" PGA package with a 2.54mm square pin spacing. This means it fits in a protoboard and is compatible with the 5V logic commonly used in homebrew projects.
In a way, the Socket 4 Pentium is the upper limit for homebrew with standard methods. Starting with the Socket 5 revision of the Pentium, the packages had staggered pins and required 3 Volt power supplies. Bus speeds also quickly exceeded what is feasible on a protoboard. Competing processors at the time were already fine-pitch QFP packages and 3V. Anything else of that era or newer will require a custom PCB.
So because it is the apex of protoboard homebrew (as well as completely absurd) here is a Pentium CPU in wirewrap sockets, freerunning at 25MHz.
The CPU is rated for 66MHz, but at that speed draws over 3 Amps of current. If I've calculated correctly, that would be enough to exceed the current carrying capacity of the wiring I've used.
I just love how ridiculous it looks, taking up most of the board space, and with that heatsink and fan.
So I drew Logan’s design the same night I posted Roman’s and then I just like... didn’t post it? Originally I was just gonna post it the next day after work, but I kinda forgot to
Anyways here it is. As is, Logan’s is pretty basic but it works cause I don’t think he’d want something super flashy.
One thing I’d like to note though is that actual blue goldstone is very sparkly, so despite the fact that you can’t see it in the drawing, I’m givin our boy some glamour. Hope you like the design, next will probably be Janus’ or Remus’
“Alice asked the Cheshire Cat, who was sitting in a tree, “What road do I take?” The cat asked, “Where do you want to go?” “I don’t know,” Alice answered. “Then,” said the cat, “it really doesn’t matter, does it?”
“If you don’t know where you want to go, then it doesn’t matter which path you take.”
FAT citrine facets, boulder opal smile, and rhodochrosite nose in sterling silvers, copper, and titanium for a wonderful friend and supporter of my artwork. We started this project back in 2018? 2019? I don’t remember when exactly, but it took FOREVER to find the right stones to accompany the boulder opal start for the design and then covid prevented us from meeting up at the annual gem and mineral show in my city in 2020. I can’t believe its finally finished 😌
It's been two years now since I started my first foray into wire-wrap prototyping. My 68030 build, the state-of-my-art from 2019 has spent most of the last two years sitting in a box.
I had gotten it running BASIC at a quarter of the speed I had hoped for, and if the wind blew just right sometimes I could even get it to use the 68882 for maths. It worked, but only just. Too unstable for any further work. I had big plans for it, but could not continue without addressing its problems.
Well, finally, I have new progress. I ordered a PCB of the main board — exactly as it was laid out for the wire-wrap prototype.
My hope is that a proper board will help with the noise issues I was having with the wire-wrap board.
A couple hours soldering, and it was ready to move all the parts over from the prototype. Since it was made from the same schematic, and was indeed the same file I referenced for wiring the prototype, it should be that easy.
Fingers crossed it works at least as well as the prototype.
So I kinda got distracted from my Sanders Sides jewelry
My mom showed me some pictures of some awesome spider earrings and I remembered that I had a roughly ear sized spider statue thing in my room, and I just ran with it. I didn’t make the statue itself, just the web and the dangly bit at the bottom
I’m justifying this as it possibly being a prototype ish thing for Virgil’s ear cuff, his is probably gonna be more low key and definitely more Hot Topic inspired, but I really like the idea of a spider themed thing for him
Anyways, pictures are under the cut in case anyone here has arachnophobia
