To be honest Feiopa I have serious doubts as to whether or not this 90° rotator is going to work without ground planes but the success of your pga tower gives me hope lol. But trying to stuff 180° in there and expecting it to work without ground planes phew, 😓 that means every trace travels past by …

If using the 5 volts, be sure to use a separate resistor per LED. A shared resistor might yield very uneven brightness in the LEDs due to differences in forward voltage drop and current. If expanding on my reply. Yes, I meant to imply seperate. :-) Btw, I highly suggest if you ever get the chance …

You can sometimes use the spare turbo led header as a power led if it is a non turbo mobo that just gives you the header so you can make your light go. But, if you want a lot of LEDs, what about using 5v fan to molex adapters and a inline fan slow down resistor (idk if that resistor will be correct, …

Okay, now that the bugs are all ironed out of that. I will soon make the ultra version. Going to require shifting the atx power over slightly. This should be the only required change. Aside from changing the model displayed on the pcb of course. If I get around to experimenting with different …

Gigabyte iRam is working! The 3.3v aux light on the diag card I assume will light if I hook up 3.3v vsb but I left it unconnected. I would imagine that the iRam might actually use that, so I may connect it later.

Well, looks like a success! In the following images you’ll see results in bottom slot, and in top slot. The top slot is currently the only one soldered up. The rest are free floating. Wanted to test before finishing up. :-) A note, be sure to push down on the pcb near where you are soldering. …

Note that you can "park" DALLAS chips before putting motherboards to store. The RTC will be shutdown then. https://www.vogons.org/viewtopic.php?f=46&t=64819 Oh wow, that’s very clever! Not a hole lot of need to do that on my converted Dallas boards though as they take a normal full size coin cell …

I don't want to ruin the party :D But do you realize how slow the i440FX chipset with EDO RAM is, right, especially in games? Even PII Klamath is greatly bottlenecked by it. Mendocino or even Coppermine would be like half performance compared to 440BX boards, at best. This is interesting excercise, …
