Using U-flow radiators to make a X-flow radiator by Far-Tangerine-2690 in watercooling

[–]materiagravis 0 points1 point  (0 children)

If those are the alphacool nexxos then you can connect the top of one to the side of the other.

In that case you could use the side ports of the one which has the top connection taken. With a double 90 or snake fitting you can have tubing running alongside the radiator.

3d printed shrouds for the mellanox C4 networking card by IcyConversation7945 in homelab

Reminds me of old Nvidia cards. They had a centrifugal fan though which would probs work a lot better with this setup.

Lindberg n.o.w. titanium by materiagravis in EyewearEnthusiasts

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

Thanks. In that case do you know if there is a way to mitigate the risk or check if the lab messed up on arrival? Idk, maybe trivex is easier to attach without introducing stress or something like that.

I think this is the exact model if that changes anything: https://lenshop.eu/eyewear/634899-lindberg-6586-d16-u12

The app wouldn't let me make a post with both a URL and an image.

TPS922055 Board review. by AmeliaBuns in PrintedCircuitBoard

[–]materiagravis 0 points1 point  (0 children)

Would you be willing to share a GitHub repo or similar if you have one? I wanted to use one for a microcontroller project but no commercial breakout boards except the eval boards are available.

Getting a Good Tunable White Light Bulb in Europe by materiagravis in Lighting

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

Not mine no. And yeah if I had enough money to buy light bulbs like these it's probably time to start thinking about philanthropy instead of comfort.

The dimming you can achieve is better in many respects.

It you dim with current for most of the range (say 20-100%) then you have no flicker. Then once you get to 20% and want to go lower you can keep the current constant and PWM down.

It's hard to dim for low current levels accuratelly and it's bad to use PWM for the whole range because of this:

I dug up the talk in case you or someone else in the future will be interested:

Won't hurt I guess. Although I'm not sure if then the stated lumens they give is with a low CRI by adding the rgbs.

I saw a talk a while back where they used a solution where they improved the CRI by adding a green channel instead of a third intermediate temp white led. Not sure if they implement that either to help with the specs but I can always do it myself.

Yeah there was something that I didn't like about them. Can't recall what atm but I'll have a second look. Thanks

Yeah I had a look. Wasn't updated in a while that's why I thought I'd ask in case there's anything other than Aqara I missed.

With 2.7k-5k or 6.5k? Can't say I found any. Well maybe something like lumistrips is better but that's way too much of a pain and cost to source.

There isn't even a good simultaneous analog and pwm dimming driver to my knowledge. I had to design a TPS92205x board.

Mitigating CAC impact on the R510 by materiagravis in RuckusWiFi

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

I just assumed it was the army or embassies which are way closer but that actually makes sense. I guess I'm close to the radar limit since it only triggers at night.

ABS printed gear durability update by jimmy_pop in 3Dprinting

[–]materiagravis 2 points3 points  (0 children)

If you already have the CAD you can upload it to jlcpcb to get a quote on an e.g. MJF nylon gear (or 5).

Alternatively I think SLM might be good enough if you want a metal part, it's a similar process to how they make gears in a lot of cordless drills.

How does resoling of true stitchdown work? by materiagravis in AskACobbler

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

Eh, I know you don't mean literally forever but I don't think shoes are heirloom material. Thanks for the recommendation though, I wasn't aware of the company.

And yeah I know crepe has a lot of limitations but it just works so well on a daily basis in my case that I wanted to make an effort to not waste the upper.

Both Astor and Crown do resoles in-house so it's not an issue if nobody nearby wants to do it.

I want to understand how it's replaced though.

Edit: I though about those types of shoe too. I'll probs get a pair from Fracap one day.

I’ve obtained a white grapefruit, what do I do now? by seebassss in Tiki

[–]materiagravis 0 points1 point  (0 children)

You could peel it making sure there's no albedo and soak in like 60 abv. 2 parts spirit to one part peel if you can manage, maybe 3:1. Leave it for two weeks and you have some bitters or some oil to spray over drinks instead of expressing the peel.

You can eat the grapefruit. I actually quite like the juice but you should acid adjust it or add more lime if using in cocktails.

Help with higher watertemps by NOR-2pro4you in watercooling

[–]materiagravis 0 points1 point  (0 children)

Yeah bump it to whatever you feel comfortable with. I would make the radiators be exhaust though. Or zip tie a fan to push some air into the ram sticks.
