This is my idea of how to relax on a Sunday evening. I re-wired a SCART cable from scratch! It's for analog RGB on my Sega Master System. The SCART cable was poorly and incorrectly wired, when I bought it, and the red output kept crapping out. Works perfectly now!

I'm not much of a gamer but I love the old 8-bit machines from the 1980s. They're really fun to play, and ROM hacking is great fun too. Alas, I don't get much time for these old machines, because of Libreboot and related activities.

@txusinho If all you want is GNU+Linux or BSD, the GNU GRUB and SeaBIOS payloads are fine.

Linuxboot is nice because you could have things like network boot, and you could also have full disk encryption (including /boot) with full LUKSv2 support (GRUB can do FDE including /boot/, but its LUKSv2 support is very cursed, so it's still recommended to use LUKSv1 when booting with GRUB). Linuxboot's uroot can also parse grub.cfg files, so it's a drop-in GRUB replacement.

How to get the most out of your X200. Don't merely flash it; upgrade the default boot flash! With 16MiB boot flash, you could easily fit a linux kernel and tiny minimal OS inside initramfs. I'm planning to integrate Linuxboot in Libreboot, in the future. yewtu.be/watch?v=iL_bVls62Ag

@selea the thinkpad w530 is not supported by libreboot, and cannot be supported due to Intel ME

I'm doing a Libreboot X200 video: the 8MiB flash has been replaced with 16MiB flash. Completely useless at present, but I plan to create a version of linuxboot (coreboot payload) with linux-libre, and put that in Libreboot. For this, at least 12MiB of flash is recommended.

do you remember, once upon a time, my saying how much i dislike the ch341a?

here's a new video to jog your memory

yewtu.be/watch?v=k80Zqj3fMtM

CH341A is *garbage*. Data lines are 5v, they should be 3.3v (can still flash 5v ICs on 3.3v usually). Insufficient decoupling (must add capacitors). WP/HOLD on 25xx pins shorted directly to 3.3v, rather than via pull-up resistor...

Don't buy it. Save your money!

Pics show mods *I* did, to fix the issues. However, it's still bad at ISP flashing. For non-ISP (DIP8 in ZIF, or SOIC8 in ZIF via spring socket), it works great. I'll use this to flash winbond ICs before installing them in the X200T!

I'm thinking of ch341a. Lots of people have success but they don't do the 3.3v data line fix, so the IC doing SPI is directly powered off of +5v. When you do the fix, you run it off of the 3.3v buck converter. I had reliability issues with ISP after that.

IDEA: Add 2nd buck converter?

I think that the 3.3v regulator on a ch341a probably doesn't provide enough current for both the ch341a IC *and* isp flashing, so after doing the 3.3v data line fix, a 2nd 3.3v regulator is indicated (for isp)

Has it ever occurred to you that the internet, as we know it, has existed for about 30 years now? The internet has actually existed for about 50 years, but the Linux kernel became available in 1991 and the internet started kicking off commercially around the same time. 30 years!

trans.chat/ is live! It's a transgender wiki and provides chatrooms for those who need support. TransChat replaces the old site, "Transit".

The old Transit IRC channels have shut down! People who wish to enter should check out the new channels listed on the new site.

Any transgender community claiming to be the old Transit community is fake. The new chatrooms are named TransChat. Enjoy!

Don't buy ch341a, but if you did get duped into buying one, this video tells you how to make it safe to use. By default, it is unsafe to use.

The video is uploading and processing now. I really went for a "this game sucks" vibe like in Angry Videogame Nerd, but instead saying: "ch341a sucks" - and that is literally the title of the video.

I hate ch341a, and i hate *myself* for now becoming part of the problem, but i want people to stop asking about it on my IRC channels. So I'm documenting how to use it safely, on libreboot.org

The ch341a is sold by a company that simply does not care about the quality of the products it sells

I give up. I tried to get people NOT to buy ch341a (SPI programmer). It is unreliable (for ISP) and poorly designed. I'm documenting it just so people stop asking about it.

By default, it has 5V data lines, but your flash is 3.3V. You can fix that, however! I'm doing a video.

Watching House of Cards. The original British BBC series, not the American remake. Haven't watched it in years, but it's great. In the original BBC version, the antagonist is a *conservative*, meaning right-leaning. In the American version, the antagonist is a Democrat (left-leaning).

Francis Urquhart is the greatest villain/antagonist ever invented. Certainly more evil than Frank Underwood. Some say the American series is better; some may indeed think that, but I couldn't possibly comment!
