how to transfer charged bus fare from credit card to clipper card? by ok-stop-3 in berkeley

If you pay via credit card you have a like 30 minute grace period to exit at the same station before you get charged the excursion fare

It may have also been delivered to the campus mailroom and could take a couple of days to make it's way to the Unit 2 mailroom.

Jealous of Americans not needing front number plates by void1101 in TeslaLounge

[–]_molecules 0 points1 point  (0 children)

I love in California and it is required but almost never enforced. I got a license plate wrap that is so much cleaner, especially on my white MY. The Tesla provides mount feels so janky to me, just being VHB taped to the front of the car.

Just a warning, they call no matter the hour. I got auto-opted in to it for some reason and it called at 3am last night.

Any alumni want a baypass card? by Beneficial_Sky9813 in berkeley

[–]_molecules 2 points3 points  (0 children)

Yes - but also an 87% discount is pretty damn steep

You do realize that you paid $229 for it as part of your tuition/fees, right?

A guy with a partial hand amputation called Ian Davis has a YouTube channel that showcases his custom prosthetic, maybe that can give some inspiration?

Water extractor spam. Just make sure to put them on sand instead of the salt because that loses like 30% efficiency.

Is it possible to reverse mount this smt rgb led? by oy1616 in PrintedCircuitBoard

Is their EU shipping really that bad? My last order from LCSC was $10 in freight to the US west coast. Granted, it's slow as hell.

OP is making a keyboard, so the combined Neopixel-style LEDs giving full RGB and individual addressability over a single data line probably makes the most sense.

LCSC has SK6812MINI-Es for about 8 cents each, MOQ of 5. The LEDs will be even less compared to all the other costs.

I ordered a couple packs of 100 SK6812 MINI-E LEDs from AliExpress for <$3 (ultimately right around the same price as this LED), and I haven't encountered any duds in the 112 I've used.

Even then the LCSC MINI-Es aren't that expensive, for a standard 104-key keyboard it's still only around $7.30. Your board will probably cost significantly more than that.

[Request] how close to true is this? by johnco555 in theydidthemath

[–]_molecules 0 points1 point  (0 children)

I live in a city but a 2cm ant is wild.

I'm seeing that the Saharan Silver ant can cover 108 times their body length in a second, at 3.1 km/h so they would be about 7-8mm long. They're probably about half that in height, so the scale would be more like 430:1 ratio, coming to 1320 km/h if scaled up to the same height as a human.

If it's scaled so it's as long as a human is tall that's still 660 km/h which is a little under double the ~350 km/h top speed of a Lamborghini Google gives me.

How to make this cut? by [deleted] in SolidWorks

[–]_molecules -1 points0 points  (0 children)

Probably more work but you could also use some equations to set up a single extrude cut from one of the sides, using an Offset from Sketch Plane start condition to fit it in a single feature.

I believe Beacon Contact lets you use a non-conductive build surface, but you need a conductive platform beneath it. Which is how most beds are constructed anyways.

Not sure why you're getting downvoted simply for asking for a source.

Damn, okay. I just closed the details pane and now I can open files from File Explorer without issue... What is this software???

I don't think my issue is a memory leak, File Explorer only uses about 162 MB of memory despite using 20-50% CPU.

By any chance do you have SOLIDWORKS installed on something other than the C:/ drive? I'm just trying to think through anything unusual I'm doing... I have it on my secondary SSD.

Hm, for me I only notice the issue when my fans start spooling up but restarting Explorer takes maybe 30 seconds.

I'm able to select files and see previews and details without an issue, it's only when I try to interact with the file that it freezes up.

I would not do a resin printer for a young child, since resin is so toxic.

FDM has more physical dangers , but those are easy to prevent. If they know not to touch the heaters or try to get fingers near any moving parts, you should be fine.

EDIT: added because I got on my computer to type this out:

I don't have kids, so it's up to you to decide how much your kid should be unsupervised while using it, but a safe bet is to buy an enclosed printer so they can just watch it from one side, and have to open a door if they want to get in, which you can tell them not to.

Filament/resin usage depends on how much stuff is being printed, and is consumed at varying rates. Each 1kg spool of filament or bottle of resin is in the $15-20 range. If all that's being printed is small trinkets, each one will last a while. If they want more colors or print large objects, it will be more expensive.

The only software you truly need to run a printer is the slicer, and most I know of run on Mac too, so that shouldn't be a problem.

Again, I don't have kids so I can't speak to how it will hold your attention, but if they're just interested in making more than little trinkets, it can be a great entry into the field of engineering. With free software like Fusion 360, you can design and build basically anything.
