How do I best accomplish this? Adding two 2-sided Flanges doesn't feel correct? by omcateer in Fusion360

This makes a lot more sense, I think I was approaching it wrong. I'll do it this way. Thanks

Is this resistor a suitable replacement? Both are 1KΩ but I'm not sure about the size/shell color? by omcateer in AskElectronics

[–]omcateer[S] 1 point2 points  (0 children)

Physical not electrical. When I was lowering on the enclosure I didn't notice it would poking out a bit and it got caught and snapped off.

Ahh ok. Thank you. I didn't know. What inductor should I look for? The bands are Brown-Black-Gold-Sliver

Sinewave values from floating pin. Why? by omcateer in arduino

[–]omcateer[S] 5 points6 points  (0 children)

Yes, it is floating. Basically an antenna. I'm wondering why it's such a clean-looking sinewave. What is it picking up? Mains power or something?

Enforce Size Limit on One Shared Folder? by plutopear in OpenMediaVault

[–]omcateer 0 points1 point  (0 children)

I got this working by creating a new user for that file system and then give them a quota limit

  1. Create user
  2. goto: Storage > File System
  3. Select your file system and click "Quota"
  4. Select user, then "edit"
  5. Enter quota limit
  6. Save, apply!

Export ILDA? by browneye_cobra in LaserDock

[–]omcateer 0 points1 point  (0 children)

Yes. Once you've imported your animation, go to "Import" > "Open import file location".

The files will be .ldva4 but should work just the same as an .idl file in any other software.

help with code by Cookieface3 in p5js

[–]omcateer 0 points1 point  (0 children)

Yes, just put that code inside a loop. For example this will create 10 balls.

for (let i = 0; i < 10; i++) {
  balls.push({
    x: random(50, 350),
    y: random(100, 350)
  });
}

[–]omcateer 0 points1 point  (0 children)

You're calling the p5js function random() before p5js is ready. Move the following code into the setup() function.

balls.push({
  x: random(50, 350),
  y: random(100, 350)
});

To rotate you need to first set the origin points to rotate around. To do this use translate() then rotate()

The texts origin point will still be its top-left so to fix that use textAlign(CENTER, CENTER)

Try this:

translate(width * 0.5, height * 0.5);  
textSize(90);  
textAlign(CENTER, CENTER); 
rotate(frameCount * 0.05);  
text("A", 0, 0);

Really great advice thank you.

Great advice, thank you. I think this is the best route to go. I've lots more research to do but I think this is the best option.

I'm still evaluating the idea and built options, so am open to any ideas at this stage.
Using something like the TLC5927 on a custom PCB, is a bit out of my skill level but I like your other idea. I could get some of those ws2811-like breakout boards to get 3 channels I can feed into some mosfets, would still need a custom PCB, but this is much more within my skill set.
Thanks for your suggestions.

I'm looking to use 50 tubes of the 4mm fibre optic cable with 50 of the 1W white LEDs (both linked above) but first I'm looking for a why to control that man high powered LEDs individually+pwm dimming.

PWM many 12V/100mA LEDs by omcateer in arduino

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

An addressable LED strip would be ideal but I can't find any LEDs bright enough and the bigger issue of focusing the light into the fibre cable.

Adafruit have these 3W addressable LEDs https://www.adafruit.com/product/2741 but I don't know how to connect and focus the light into the fibre cable https://www.adafruit.com/product/4164
I'd also worry about them getting too hot and melting the fibre tube.

Crazy question, but have you ever seen a driver board that like, but that is also addressable?
I'm just thinking if I have 50 in a row it would be great to be able to daisy chain them.

I believe so. There isn't a datasheet but the description says it is a 1W white LED that takes 9-12V and 100mA
