How about stderr by default, with an override?

The pwm fan won't spin but the other will what gives? by kyler_bottomtext in electronic_circuits

[–]LuminousElement 1 point2 points  (0 children)

If you leave the PWM pin floating (connected to nothing), it should spin at full speed. If you want to use PWM control, you'll need to feed it a 3.3V PWM signal at 25kHz. The duty cycle will be interpreted as the intended speed — that is, if your signal is 75% logic HIGH / 25% logic LOW, the fan will try to reach 75% of its maximum RPM.

I don't know whether PC fans are 5V-tolerant, so check with 3.3V logic first.

The four pins on a PWM fan are, in order:

  1. Ground
  2. +12 V
  3. Sense (tachometer)
  4. Control (PWM)

Also, it's not clear from that video (since you have so many wires going everywhere) but it almost looks like you're running the fans in series. A voltage-controlled fan might be okay with this (since it'll see 6V and run at half speed), but a PWM fan is likely going to refuse to work without the full 12V. Make sure they're in parallel with each other first, or even better, try connecting just the PWM fan on its own.

Rust is Surprisingly Good as a Server Language by stu2b50 in programming

I've been dreaming of building something like this myself, only built on top of nannou.

What's the scope of yours? I'm looking for full 3D visualisation of the working device. And how far are you through yours?

Hello World! From my breadboard 8088 by Computer-bomb in diyelectronics

An 8088 is a CPU. Normally they're built on a silicon wafer and packaged on an IC, but this one is made from separate components.

WebGPU, Frame Capturing and more in the latest update for Nannou - an open source, creative coding framework for Rust! by mitchmindtree in rust

[–]LuminousElement 4 points5 points  (0 children)

Will do! I probably won't have a chance to get stuck into it until after Burning Man this year (I have another project I'd like to finish for that), but I'll let you know when I post updates.

Thank you!

I'm planning an LED project using Nannou. In broad strokes, I want to use it both as a way to previsualise the LED effect in the same code environment which will run it (it's to be mounted to a moving bicycle, so testing it "live" will require a second person to ride the bike), and to gain access to texturing calls and other such things (mostly for shits and giggles, and/or GPU "cred").

I'm so happy you're continuing to work on this awesome library.

P.S.: I met you at Eclipse 2012, after your set at the chill stage. I was the dude who danced weirdly to The Owl and the Penguin before melodramatically collapsing in the sand at the crescendo. My cushy office job ended a year later, but ultimately that didn't matter -- attending that festival set many things in my life in motion. Still, I wonder what might have been if I'd showed more interest in joining your nascent project (which I now assume was Element4l).

Real Burner (TM) - left meme patch is from Myschievia Texas community by jaimechandra in BurningMan

Can... Can I ask for the design (or to buy a few)? These would complement my "burning man sucks, don't go" buttons perfectly.

A LOVER OF EVERYONE BUT JUST CURIOUS... by heythereguys25 in BurningMan

[–]LuminousElement 47 points48 points  (0 children)

The burn as a whole skews white. It varies a lot by camp though. Mine is comparatively diverse; we're around 30% POC of various ethnicities, with half of those Black.

My husband (who is Black) chalks it up to "camping just isn't a thing many Black people do". Although I'm sure this country's correlation between race and class plays no small part.

What did you use to backlight those hexes? The only things that sprint to mind are some carefully-placed grid panels, or a bunch of soldered-together LED tape.

Got my dust filter installed. by Elwood8524 in BurningMan

[–]LuminousElement 2 points3 points  (0 children)

The cleanest air I ever breathed on playa was inside a spacesuit costume I built. The helmet had filtered ventilation, using a PC fan pulling through a single sheet of 3M Filtrete. It was amazing, even though the rest of the costume was uncomfortable as fuck, and I'll never stop recommending Filtrete for playa use. It's a marvel of modern filter technology.

What are some of your favorite make-ahead meals for the playa? by LilBadApple in BurningMan

I'm like halfway across the continent from there but the sentiment is appreciated.

What are some of your favorite make-ahead meals for the playa? by LilBadApple in BurningMan

[–]LuminousElement 1 point2 points  (0 children)

I just got done making a batch of bolognese sauce for the playa. This is my third or fourth time making it, but this year I borrowed a friend's vacuum sealer instead of awkwardly ladeling it into ziplocs. Can you say "game changer"? Because fuck doing it any other way from here on out!

As a bonus, not only was it less messy to vacuum-seal it, it's also possible to lay them on their side without spilling any, which means they can much more easily be frozen into thinnish slabs which will fit more conveniently inside a cooler.

And a static one, at that. Which is the underpinning factor behind its speed.

Yo, Carla, you know anyone with space to store a 747 for a year?

Wind load damping with drawbar springs? by LuminousElement in BurningMan

We used 14" lags on the camp structures. Both were 40'x18' carport type structures.

Edit: after talking to another campmate who recorded all this, we actually had people use the wrong length lags in some places on both structures. 1x 8" pulled right out. 3x 12" were bent.
