IF the engineer that reviews PCB's accepts this, I'll be pretty surprised but for the lols, I'll save it to cart to see what happens.

I wonder if you could make a rear bracket version entirely out of pcb. Like attach it to the bracket you already made and have it all coming out of the rear. Even mount the button on the bracket and such. Just brainstorming. The way you made it there is pretty easy to use. Just sit behind the …

I assembled and done some light testing to one unit. It looks good and what limited functionality I tested, works well! I am really happy to say that you can access the settings terminal over the usb mini-B port, even windows sets up the correct drivers for you! This particular unit is going to be …

I assembled one PCB just to see how it looks and I think it came out well!

Hey Based off of my tinkering with making a new vrm for my own socket 7 board, Sphere asked me to look into making a step down voltage converter for the tweeker. For voltages I have 1.6 -> 4.0 available in increments of 0.1v from 6 different resistors. Attached is a PDF of an excel sheet I used to …

San I see the ps2 thing? sounds interesting. Theres the kicad files. I mentioned it a while ago, it's a 2 part thing. The PCB with the ps2 port and headers & a 3d printed part to mount it to the case. It was just all made together to fit in a blank serial port I have spare. Made it for the soyo, …

I have ordered the boards. I changed a little about them before ordering. First order from PCBway, so it'll be nice to compare them to JLC EDIT: A T board style thing like suggest would be handy alright. I'd just have to make the board bigger. The datasheet for the murata module seems to highly …

Alrighty! I think that's done. I added a test pad for an alternative way of adding a vin voltage to the murata module. I know it seems weird but it's just there as an experiment. Probably best to cover it with tape if it's not being used. Once again I made a rough 3d model of the murata module, …

Depends on how hot the thing gets. I have no point of reference for that. Initially it sounds like a decent idea, I think it's better off fed off 12v and it would give the 12v rail something to do (which is always good)

Got a suggestion for a different one? :-) I found lab psus. Which I assume would be superior. But they don’t fit in the case.. I think this is a good part of testing this btw. You and I know that people are going to buy this exact thing whether we tell them to or not. So may as well test it. But I …

I put thought into a the very same adapter but my personal scepticism of these parts tells me not to count on them for a CPU.

Rough edits to fit the 20amp version of the module. The board is wider and taller as a result, it may still fit albeit a bit tight.

Always derate the amps or watts by certain % for headroom if datasheet did not specify derating. Say you have this module rated up to 12 amps, I call this up to 10 amps times 2.0V, 20W total, For 3.3V, this is 33W. Good to include a jumper if you can to get it to 3.5V or so for some CPUs. …

I decided to add a input filter cap. The value of the cap doesn't really matter too much, something like 22uf -> 47uf should be fine. It does look like it's in a really awkward place but I have to make sure nothing is interfering with pin headers, the sides of the heatsink are thick so there's …

Alright, I think that's it. I think I have everything wired in correctly at the moment. Traces are as beefy as I can make them, foot prints all seem right, I think everything can be hand soldered fairly easily, triple checked the resistor switch map thing. If anyone is up for looking at it to see if …

I done a little recalculating with the resistors and I got a larger list of supported voltages with one less resistor. The text is a bit small which is a shame, not sure how to restructure the table to be more readable. It would be handy with there was an easy scale option in kicad 😐 Here's hoping I …
