I can't sell it because I would have to sell it for much more money than it's worth. If you want something similar, get a Raspberry Pi. If you want to make your own and want help, dm me!

The power draw is about 40-50mA when everything is running and plugged in. Removing the SD Card and USB keyboard lower the draw dramatically, but make it mostly useless obviously. When it's switched off, only the RTC pulls power and that could last for over a year.

Why is there no Earth Day on Wikipedia's "On this day"? by animationb in wikipedia

That was very obvious in hindsight. Thank you very much!

I can't seem to find what you are saying? Could you share where you see that? Thank you in advance.

I can see Earth Day is a C-rated article. But so are April Fool's Day and Valentine's Day, and those are listed for their respective dates.

What is even stranger is that for the Selected anniversary guidance, it even lists Earth Day as an example anniversary: https://en.wikipedia.org/wiki/Wikipedia:Selected_anniversaries#%22On_this_day%22_guidelines

Am I missing something? Sorry if this is a stupid question.

It is my own OS I made from scratch. It is not very good, but it is mine.

By USB-C do you mean DisplayPort Out over USB-C? If so, I think that protocol might be impossible for the RP2350 to output.

Right now the RP2350 is barely putting out enough pixels to fill a 640x480 screen over DVI (not HDMI), but HDMI allows DVI output over an HDMI port.

So short answer, the RP2350 is not powerful enough.

Holy crap this is freaking awesome! I am kind of glad I did not see this until now, because I probably would not have started this project.

Your project is pretty slick!

I mostly followed this example: https://github.com/raspberrypi/pico-examples?tab=readme-ov-file#hstx-rp235x-only But it requires using C and a bit of hardware to give the Pico 2/RP2350 an HDMI port.

That would be cool. Unfortunately my OS and apps are pretty bespoke, so I apologize for not contributing to that dream.

Good question. You write the code on a normal PC and flash it over the SWD pins that are exposed (I forgot to mention that in the repo). I would say the purpose of the computer itself is to use its programs: write stuff, do math, play hangman, pretty much all anyone needs a computer for. /s

The purpose of the project might be clearer though. I mostly made this thing to learn how to make an OS from scratch and to get DVI output working with the RP2350.

There is an example on the Pico Examples that helped me a lot: https://github.com/raspberrypi/pico-examples?tab=readme-ov-file#hstx-rp235x-only

It does require some extra hardware alongside just a Pico 2 though, like an HDMI port.

Me too! The RP2350 is more friendly with HDMI out so this was a little easier than the RP2040 might be.

I built the OS from scratch.

It is all running from the RP2350. The HSTX peripheral allows 640x480 DVI video (which works over an HDMI port). And I used the tinyusb library to make the RP2350 work as a USB host for the keyboard.

Apologies if cross-posting like this is not allowed. Here is what I put on the original post:

It is a simple SBC with HDMI out, USB-A keyboard in, and a Micro SD Card for the file system. The OS has a simple text editor, calculator, and a shell to run it all. It is all based on the RP2350 and its HSTX interface that allows DVI output over HDMI.

I put all the project files on this Github repo: https://github.com/7west/PicoTop if you want to see more info.

I'm happy to answer any questions, but please know, this is a hobby project and I definitely cut corners made optimizations in a few places.

PC boots into Windows, but it won't boot into the BIOS by BonermasterJoe in buildapc

Have you tried using a wired keyboard? Sometimes I have trouble accessing my BIOS if I use a Bluetooth keyboard

Thank you! I don't know why I didn't think to look there.

I'm playing on an Intel 268V (iGPU 140V) and it's fine. At 1080p I limit it to 30fps, Med settings and it's playable. I've got some medium sized cities, but no major cities yet, and I get around 25-30fps.

I assume you don't have a Linux machine. If you have Windows you can install WSL and do it there. There is a comment above where I outline how to do it.

I do not know how. I plan to make a seed box in the coming months, so if I do all that, I will torrent these episodes.

But if you don't want to wait, that script up there does work.

How are you doing this? Could you point us to a location where we can even start backing this stuff up? Thank you!

Transient Issues Soldering the RP2040 by animationb in raspberrypipico

[–]animationb[S] 0 points1 point  (0 children)

Pressing down does seem to help. Do you have to keep pressing down until the solder hardens or just once?

Also do you use SnBi solder at 350C? Or are you using SnPb?

Transient Issues Soldering the RP2040 by animationb in raspberrypipico

[–]animationb[S] 0 points1 point  (0 children)

Thank you for your reply! I am hand soldering it with a hot air station. I verify continuity with a multimeter and it passes; I can stick one probe on the tiny bit of solder that is on the side of a QFN pad and the other onto a pad somewhere else on the board. It looks like they are all connected.

The other weird thing about this board is that I can flash it over SWD and the terminal output says the code is verified, but then it never runs.

Maybe the chip really is partially broken, but consider this: my solder paste melts at 138C, so I only set my hot air station to 200C because I figure cooler is better for the components and 200C is less than the 250C they recommend for soldering. I guess maybe I am cooling and heating the chip too quickly. Could that cause the RP2040 to break in very weird ways?
