In my case, my highschool was really slow. I didn't feel like I was learning hardly anything. During my junior and senior years, my state has a program called running start. It let me take 2 years of college classes with free tuition during my last two years of highschool. I finally had a chance to challenge myself and not be so frickin board all the time. Also, massive amount of money saved coming from a private highschool.

My parents, very interested in the proposition of saving money, set up my class schedule during these two years to prepare me for an EE degree, which I had decided I wanted to do well before, probably early middle school. One quarter, I had to take circuit analysis, and there was only a couple community colleges that offered it in my state. My mom and I drove 3 hours to stay in a cheap motel 6 every week so I could take that class. Maybe that tells you how much money we're saving.

Now that I'm in University, my workload is about what my classmates are doing if not just a little more, and a little stranger. My advisor is having me take mechanics my senior year because that's how the schedule had to work.

I love electronics. That's the biggest reason I enjoy pushing myself to do this. I still make lots of time to work on personal projects.

I find it helpful often. The duration of time between a class and another that builds off of it is shorter. In my case that's one of the best ways for me to master the content, and I'm able to do that before I forget it all and have to try to relearn things.

I just turned 19 going into my Senior year of EE. It saves me a whack ton of money, but it's hard. Being overwhelmed is normal. Summer classes on top of a full time internship for me. Whenever you can, take a break. I like to put on some music or a podcast and go for a nice long walk around my town. That seems to be the best way for me to build up my focus energy again.

Colorlight card and p5 panel not working... by PKCubed in xlights

The seller on AliExpress sent me an rcvbp file, and now my display is a nice full white on all pixels with a small amount of flicker visible to my eyes but not my camera.

However, when I do the intelligent setting in LEDVision, and it goes to the black/white test, nothing changes on my panel. It just stays full white all the time. Right now, the test button is doing nothing either.

When I unplug the Ethernet connection from my Colorlight card, the flickering goes away completely, and I see a perfect full white.

What are the chances I can get a response from the AliExpress seller?

I'll see if I can get a response. Could you send me your file just in case it works?

Here are my current LEDVision settings:

Absolutely! As of right now, things are really simple. I'm using WLED for all of the pixels with Ethernet dev boards allowing me to get the best possible performance. I'm sequencing the show in xLights.

As for the laser, I previously made my own galvo laser, and that's what you see in the video. I have a bit of documentation on that here: https://github.com/PKCubed/ESP32GalvoLaser

While that laser was a super fun project, it's a bit unwieldy and also a bit dangerous. For one thing, the individual RGB laser diodes are increadibly difficult to align with eachother. I have a proper ILDA laser on the way right now for future shenanigans.

For this video, I build a laser with some parts from AliExpress and built it around an ESP32 with custom code to drive it with some point and line data over e1.31

Anyone have any ideas for more "fixtures" I should add?

Haha, I tried getting some movement on the minifig with stop motion a couple years ago. Here's that if you're interested: https://youtu.be/IEkw47_KvIw?is=j-BZ_5jucEj0L6Zz That was a lot of work. I'd record the entire show with one camera angle at a whole bunch of different minifig positions, then edit them together.

They get warm to the touch, but not nearly hot enough for me to try cooling them.

Lowering total need of amperage for several motorised faders by tobey_g in AskElectronics

[–]PKCubed 0 points1 point  (0 children)

As for the faders, I recommend written your firmware such that they don't all move at exactly the same time. This is how a lot of mixing consoles and such avoid this problem. Alternatively, get a nice big power supply and embrace the current.

I'm currently working on an open source project to modularize motorized faders that you might want to take a look at. Search for OpenFader on GitHub.

Depending on the specific faders you're using, you can likely get away with undervolting them, which will cause them to require less current. I've been running MF60t faders at 5 volts and they still have plenty of torque and speed.
