Glasgow is probably the most useful tool I have access to aside from oscilloscopes and logic analyzers. So versatile and easy to adapt to the problem at hand.

Can confirm, got myself 10 boards and the shipping was 18 usd (to Sweden in my case). VAT is also added to the order, so there shouldn’t be any surprise extra charges when it arrives. Splitting with friends is the way to go.

Woop, placed my order. There are a few left. Excited for the BIO 🤘

Got tired of this project but I finished the important piece of the puzzle. Should I just publish my nasty code as is, or try to keep working on it?

kbeckmann.bsky.social @kbeckmann.bsky.social · 24/11/2025

Did a last minute tapeout because why not 😅 (resubmission/port of an older design). Ahh now I really want to finish some other asic projects I haven’t touched in a while. This winter will be fun.

kbeckmann.bsky.social @kbeckmann.bsky.social · 22/11/2025

Yeah this will be the journey to discover. I hope to start simple and take it step by step. I don’t have to be an ibm compatible pc from the start, maybe just run some instructions and see activity on the bus initially.

kbeckmann.bsky.social @kbeckmann.bsky.social · 22/11/2025

Yes but don’t expect too much :). Will take weeks and months to get anywhere. I also have a discord where I post more small updates on my projects. If you’re curious discord.com/invite/CGTjx...

Tbh I’d be happy to make it run a couple of instructions, talk a bit on the bus and see it come to life like a MCU. Being able to run the original doom or quake exe would be like a final goal but I realize that it’s tons of work to get there. And yes, learning is what it’s all about.

I’ve been trying to source Socket 7 ZIF sockets and found 2 US vendors that sell them for about $3.5 which is reasonable. Would be nice to find a EU vendor but so far no luck. Any EU suggestions? US: 1. www.peconnectors.com/sockets-pga-... 2. www.componentonline.com/product/425C...

For the FPGA, I'm thinking of ECP5 or Artix-7 or something like that. But I will need to interface with a ton of pins which can be a bit cumbersome. Need to think a bit about this. Then of course comes the gateware. But I'm thinking I should prioritise geting the "bringup platform" up.

180

kbeckmann.bsky.social @kbeckmann.bsky.social · 16/11/2025

First step is probably to find some Socket-7 sockets, make a proper PCB footprint and document the accurate pinout. This should be very doable. Then design a breakout board. Thinking of using IDE/PATA connectors. Fastest signals are 66 MHz so should be okay. Then pick a good FPGA and interface.

170

kbeckmann.bsky.social @kbeckmann.bsky.social · 16/11/2025

So I found an old Pentium (probably 133) which sparked an idea for a project. Stupid but fun? Doesn't matter! I want to build a breakout board that lets me bring up the CPU with an FPGA. Emulate the Northbridge, interface with some external RAM, implement PCI peripherals.

Yeah I’ve tried that but idk. I think I’ll try faster filters. I have a Eureka Mignon Perfetto for my espresso machine, and it produces a nice grind at coarse settings without too much fines. Maybe it’s just my pour-over technique that sucks 😅. Drawdown time is about 2 minutes for 300ml

[coffee nerd talk] I feel a bit like a failure - been dialing in a V60 brew with an 1Zpresso Q grinder and Hario filters but it keeps tasting a bit bitter no matter what I do. Gave up, brewed with a Moccamaster with standard Melitta filters and it tastes amazing. Hnggg. Should I try faster filters?

A photo of the KeebDeck Keyboard keypad and dome sheet. The dome sheet has many domes visible through the white plastic, and 8 black pieces of tape to cover where the backlight LEDs would be. The Keyboard has 69 keys with the usual PC layout, and a few extra ones color symbols and colors.

ECP5 is awesome and the open source toolchain combination yosys/nextpnr/trellis works really well. What kind of issues did you have and which board are you using?

Looks like a fun project! Sounds like there’s just some details left. Is this captured from hardware or some sort of software solution?

kbeckmann.bsky.social @kbeckmann.bsky.social · 17/08/2025

Found the root cause of the blurryness. Turns out that I had connected two of the color bits to pins that were tied to the i2c bus on the carrier board I am using, causing the signals to go all the way to the hdmi capture card and affecting the signal a lot.

Got my first capture from the top screen of the Nintendo DS Lite using a Raspberry Pi RP2350 microcontroller. Captured using PIO, outputting DVI-D using HSTX. There is still some work left to do, but it's getting there!

kbeckmann.bsky.social @kbeckmann.bsky.social · 10/08/2025

(Uhm, ignore the difference in the pattern number, it shows up on both 4 and 5. The point still stands; and I should’ve tested the code on the unit with a connected top screen first and not just rely on an emulator)

150

kbeckmann.bsky.social @kbeckmann.bsky.social · 10/08/2025

Was getting weird traces that didn’t match the expected output from my homebrew test code. Hardware vs emulation strikes again 😅 Was drawing using OpenGL and I guess I queued up too many calls or something.

kbeckmann.bsky.social @kbeckmann.bsky.social · 08/08/2025

Started working on my Nintendo DS Lite video capture to HDMI project today after weeks of zero motivation. Huzzah! Fun fact, the fastest signals here are about 10 times slower than on the N64 (~5.5 MHz vs ~50 IIRC), which reduces the risk for signal integrity problems.
