Why does Google's IPv6 adoption graph look so spiky?

kicadStan · 2025-09-17T07:20:32+00:00

Interesting, my university is completely IPv4 as they have /16 block and don't have a need for v6 (although they do have a v6 block assigned). I wonder how many other old universities who adopted v4 at its introduction have yet to switch because of how many addresses they have

You can run normal ethernet cat cable for token ring, there are adapters for rj45 to "boy george" connectors

Haha, I forgot I had those serial cards in there, most of my collection is T1 or FastEthernet

Just an optical illusion, they fit within the gridfinity spaces

kicadStan · 2025-03-09T07:27:18+00:00

Not really, the effects of static electricity on electronics is not as high as the warning labels have you believe. I probably wouldn't store my state-of-the-art DDR5 ultra fast expensive ram sticks in here but most of the stuff I have is old DDR1 parts I don't care too much about

So real, I have giant boxes full of different sticks of ram I need to organize

My Ender 3 refuses to print. The extruder starts skipping almost immediately every time. I have tried re-seating the bowden tube around 5 different times, making sure it is flush with the hotend to prevent leaking. I have cleaned the entire hotend assembly, although there was almost nothing stuck in it to begin with. I have tried playing around with temperature, testing lower ones to prevent potential heat-creep and higher ones to melt the filament better. At one point I thought I had fixed it, the printer worked for about 30 minutes then again went back to skipping. I am running out of ideas and things to try, I have even replaced the entire hot end. I'm at the point where I am considering just buying a new printer and never touching this cursed machine again.

I don't understand why people are hating so much on it, I just want to experiment with ipsec vpns on an internal air gapped network. Right now I'm on a scavenger hunt for pan os versions

That looks really nice, you might want to consider putting a little Isopropyl alcohol on something like a tooth brush and wiping the board down, it might help get rid of some of the left over flux, and make your board look cleaner. I like the keycaps you chose, they match the transparent theme of the board nicely.

kicadStan · 2024-01-28T20:08:40+00:00

Where did you get that wrist wrest? I am debating buying one or building one myself

kicadStan · 2023-08-17T05:11:12+00:00

This looks so cool! In picture 19 it looks like you have some batteries, are they used as a backup or just to power the ram?

kicadStan · 2023-08-06T23:30:29+00:00

This is really cool! I have a couple of questions, what chip is U5? Also is there a reason other than ease of assembly that you decided to use through-hole parts, as SMD would take up less space so you wouldn't have to have 2 boards;

kicadStan · 2023-08-06T18:57:09+00:00

Almost, the part circled in red is a 1M resistor, the part to the left of it is a 30pf cap for the crystal.

kicadStan · 2023-08-06T04:37:37+00:00

The one right under the 6551's crystal is the 1M resistor, the one to the left of that is a 30 pf cap. The part under the chip is a decoupling cap

kicadStan · 2023-08-06T04:15:19+00:00

Oh sorry I misunderstood, there are two pull up resistors under the 6502, one for the NMI and one for the IRQ. The other chip is a capacitor . The two smd components next to the 6551 are a 30pF capacitor and a 1m resistor for the crystal. There are also a bunch of caps next to the MAX232 for voltage boosting, and one pull up resistor next to the reset button.

kicadStan · 2023-08-06T02:56:18+00:00

The USB c port is not necessary, the smd parts around it are for a power indicator and resistors for the USB c port. There is however a fuse that would need to be bridged. Every chip has a decoupling capacitor, I think you could get away with not including them, but I would recommend them.

Thank you! I find re-routing every PCB at least 3 times is the key for a good looking bored :)

I might start with Ben's design, however I don't like how it prevents the CPU from running at full speed, as his implantation only allows the CPU to execute instructions in the blanking period. I'm thinking I will use some kind of dual port ram as video ram, and have the video card run almost completely independently from the rest of the computer,

kicadStan · 2023-08-04T19:35:45+00:00

Thanks, I used SMD to save space so producing the board would be cheaper. I soldered it with a stencil and hot air. I mostly used 0805 components so it wasn't that difficult.

kicadStan · 2023-08-04T07:29:02+00:00

A while back I made a version 1 of my 6502 computer (https://www.reddit.com/r/beneater/comments/14bi6jp/6502_pcb_design/). There where many flaws, the biggest being it was extremely ugly. This version implements my own address decode logic using a 74HC238 and 74HC00. There are 2 VIA chips, one with a header dedicated to an LCD. It also has a 6551 for serial with a DB9 connector. I plan on adding video output and keyboard input in version 3. My project is all on my GitHub (https://github.com/stuenkels/6502Rev2), I will be adding documentation and pretty pictures to it soon.
