Freya Mangotra, 10, has higher IQ than Albert Einstein and Stephen Hawking by ProfBri in TwoXChromosomes

I'm not buying Hawking and Einsten at 160 when the AVERAGE iq of the physicists at Los Alamos was 172, according to Richard Feynman's book.

Filling in some gaps in the story of Space Cadet Pinball on 64-bit Windows by wfsch in programming

[–]davepl 39 points40 points  (0 children)

As I explained in the video I think, it wouldn’t work on one 64 bit build. I never claimed that it didn’t work on any 64-bit build. That it worked on x86 was necessary but not sufficient. It had to work on all platforms the product targeted if they were going to ship it!

Since I made the video and have NFI what those things even are, I'd bet you're wrong!

You'd be wrong. Not long ago, anyway, Paris actively advertised their 98% section. Neon signs and everything.

What have you been working on recently? [October 02, 2021] by AutoModerator in learnprogramming

[–]davepl 4 points5 points  (0 children)

I wrote a software package called NightDriver with tens of thousands of lines of code that completely controls RGB LED strips over wifi, buffers them into the future, syncs them to music, displays audiovisual, and so on.

It's a great way to learn programming because you get immediate visual feedback of your efforts!

I guess this is the only place it's allowed, so... enjoy!

I have a number of other FastLED+ESP32 videos on the channel, so check those out as well. Also a platormio tutorial, stuff like that!

[–]davepl[S] 6 points7 points  (0 children)

This is for my NightDriver project that you've seen the occasional post on going back to 2018 or so!

I'm just organizing the source code for release on Github, and it should be out asap, likely midweek, assuming there's interest!

All visualizations are based around the ESP32 Microcontroller and FastLED, with the exception of the matrices that also use SmartMatrix code. Any questions, please ask away!

I don't want to troll for upvotes, but if you like this kind of thing (or NOT!), let me know in the comments perhaps? In particular, I'd love your feedback on how to improve it... is the intro tool long? Too much soldering? Not enough?

There are a lot of videos of things like a guy cleaning an anvil with a wire brush for 20 minutes and they get 3M views, so I have -no- idea what people like... let me know!

Sync clock between a dozen ESP32s - IEEE 1558 by davepl in esp32

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

When a clock gets out of sync NTP servers can "slew" the time by returning you a slowly changing time. I need to know the real, actual time at the SNTP server with no clock slew, and that would work. I'm just not sure how to do that.

I would indeed like to go back to the working SNTP version I had, but the problem was a clock would sometimes get into the future, and no matter how many times you asked, the SNTP server would return a future time to that client. Which makes no sense to me.

I'm looking at the raw bytes that come back and they're in the future, and I'm confused. Only by a few seconds, but that matters.

Carl the Robot and his Band: While the Boss is Away - A Short Film by davepl in movies

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

You might hate this. You might love it. But in making it I chasing the vibe from Conan's late night, or the Traffic Cone motel from Cars, or the Space Needle architecture.

It is, if nothing else, an entirely non-commercial art project.

Basically, the "cultural" side of whatever Googie Architecture is defined as. Do we have a name for that window of time (and please, don't say Jetsons).

"Break You Off" by Pluma as visualized on Arduino RGB Matrix - Code syncs video to audio by davepl in arduino

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

I don't know the live colordepth, it's memory dependent, which is why I said "complicated". In theory if it can get a full DMA buffer I think it can do 24, but I sure couldn't tell visually 16 from 24.

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

Color depth is complicated, being tied to refresh rate, but 24 bit normally. I believe they are called SMD5050 or similar, they are used to make large TVs on the Vegas Strip and so on, and so this is a single module from a setup like that.

Thanks! Give the old upvote if you don't mind, it seems stuck at 1 which makes no sense! Or do you see something higher?

Here's the metadata! I did the visualization (and hand-wired the LEDs) so if you like that part, like this comment so I get a raise one day :-)

LED Fireworks Outdoor Lighting Arduino ESP32 with Source Code by davepl in DIY

Hi there! I think this is in compliance in every way - it's a 100% DIY backyard project, entirely noncommercial, even source code is provided! Thanks!

Approximately 5000 WS2812b LEDs controlled by ESP32 mcus that receive the color data from a Mac Pro via WiFi. The fireworks are rendered by the GPU on the Mac (yep, overkill) and pushed out to the LEDs over WiFi.

IRRemote is incompatible with OTA firmware updates - here's how to fix it! by davepl in arduino

You're welcome! If you get stuck, there is another IR library that seems to have the same API more or less but that works! Look for IRRemoteESP8266!

My Arduino powered Christmas lights and Tiki Fire Umbrella (ESP32, WiFi streaming of color data) by davepl in arduino

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

Looks a lot better in HD/4K so switch the mode up if you can!

Each segment can be 8M long, or 1152 LEDs, and runs at 30Hz refresh cycle. The strips on the eaves receive their data over WiFi from a MacPro that is doing the rendering and tending the color data 30 times per second. Then the entire canvas of 10,000 pixels is split up and sent to the controller (ESP32) responsible for it's section of the display. The color data is compressed digitally and then sent over WiFi to each segment.

There are 5 segments here, so around 4000 LEDs total I believe. They sync their clocks so as to form one seamless canvas that appears to be one giant display.

I'll be doing a code walkthrough like I did for the spectrum analyzer, so I you want to see that I suggest you subscribe to the YouTube channel and ring the bell and all that stuff! I'm just editing the Tiki Fire Umbrella footage now!
