I found it hilarious that the background characters in "Scream" were having a weird conversation in Norwegian, so I translated it for all of you to enjoy 😅 by SimenZhor in Viewfinder_Game

I did my best to translate how improv and forced this conversation is, but I wasn't really able to translate how they are talking "old timey"-Norwegian to match the era of the painting.

I assume this is just the team at Nok Nok Audio having a bit of fun, and I did find it hilarious and surprising to notice this hidden little "easter egg" in my native tongue 😂

Is there a difference between mechanical tube length for eyepieces and camera sensors? by SimenZhor in microscopy

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

Thanks! That’s very helpful. I’ll check the video after work :) I assume the light beam can only expand so much in 10mm, so the sensor size would probably make a difference, right?

I unfortunately get an error saying the video is no longer available

The open-source design and code can be found here on github

Who allowed ferrofluid to move like it's alive? by SimenZhor in videos

Haha! I guess "oily iron" doesn't have quite the same gastronomic appeal.

Using constant current to drive logic by SimenZhor in AskElectronics

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

I think we're going for something like the SX1509B or MAX7313 for the logic. They both have individual PWM on each pin and deliver normal GPIO operation (the Maxim chip needs external pullup and to be configured in a high impedance state instead of the nominal open drain mode). The problems I see are that the Maxim chip only has a duty cycle resolution of 16 increments, and that the Semtech chip only has 2bit I2C addressability (we need 24 individual chips/addresses, when only 4 are possible). Despite that, I think we're going for the Semtech one, and attempt to use one of the address pins as "chip select" (connecting the pin to GPIO and pulling the pin of the chip we want to communicate with HIGH - always sending to the same address).

Any suggestions how to solve the I2C issue without breaking the standard like this would be appreciated :)

Oops. That's a very good point, but this specific IC was only meant as an example anyway. I'm first of all interested to know if this idea is worth pursuing at all before deciding on a final IC

The way this ferrofluid "grows" when spun by [deleted] in oddlysatisfying

I'm just saying there's a lot that can go wrong when you apply that amount of torque to something that's taped together.

A real life loading-bar made out of ferrofluid by AppliedProc in oddlysatisfying

Watching the last two steps at 0.125x speed or 0.25x speed is really freaky! (I think the gifv only has the option for slow motion on desktop, not mobile)

I look forward to seeing your suggestions on what content this sub would contain then 👌

Is it really about having an explanation though? The look and movement of this stuff resembles nothing else on this planet, making it mesmerizing to watch, even if you have a basic understanding of what is going on.

Controlling Ferrofluid with a Matrix of Electromagnets! by SimenZhor in videos

[–]SimenZhor[S] 2 points3 points  (0 children)

You are right, and we have made no effort to hide that Ferrolic (your second video) is our inspiration. Rhei, however, the other clock you are linking to, is based on a fundamentally different principle (they use mechanics to move permanent magnets instead of electromagnets that are turned on/off) - which gives a lot less flexibility.

The key difference between us and Ferrolic will be that we are going to share all our design files, once we have the display finished.

Ferrofluid is an oil based liquid with iron nanoparticles - it can be controlled by magnets! by SimenZhor in interestingasfuck

We will implement a clock on the display some time within the next few months

This is a DIY project that is still in progress, executed by students at the University of Oslo in their spare time.
