TLDR: After ten years I'm taking a break for my health. After a decade of working 10 jobs at Lixie Labs, I'm shifting to working fewer roles. While being the primary developer, designer, manufacturer, marketing guy, and more was very rewarding, it was also exhausting. ๐งต1/4.

I'll be resuming production on Emotiscope firmware in a personal capacity soon, as I still very much enjoy delivering intuitive and memorable experiences for the fans of my work. I believe that the mental health benefits from this change will lead to greater innovations. 3/4.

It's time for me to limit my scope of work and solely embrace what I do best: designing amazing things. Though I have temporarily halted production on new hardware, I am *absolutely* dedicated to providing long-term support for all existing customers. 2/4.

By the way, I then unrolled Espressif's DSP ASM code by 4x as well. This chip is now a mean float multiplying MACHINE. The ESP-DSP library is so useful that Emotiscope uses it more for the GPU core than for audio itself. That's how 500 FPS happens now.

Let your eyes enjoy the music too โจ Extremely low-latency audio processing lets LEDs perfectly synchronize to your music's notation and tempo. - Lixie-Labs/Emotiscope
"Wow" is right, I think the ESP-DSP library uses SIMD instructions. Multiplying two float[768] arrays with a for loop:.16902 CPU cycles. Multiplying two float[768] arrays with ESP-DSP:.6653 CPU cycles. Even loop unrolling by 4x is still twice as slow as the one-line DSP version.

Emotiscope Engine 2.0 is coming along great! Here's some facts:. - Max recorded FPS: 578 (was 418).- New color mode: Lava.- New light modes: Harmonics, Beat Tunnel, Pitch.- New slider: Blur. I'm nearly done! Thanks for your patience between these updates. Here's Harmonics Mode:

Hardware brag: Emotiscope's 300-500 FPS LED updates really shine here. Entire frames rendered by the second ESP32 core (and then transferred to the display) in about the same time my keyboard LEDs take to do a single PWM pulse.

I've posted about it before, but sometimes when I need to see what Emotiscope's LEDs are doing frame-by-frame I'll just take a photo while whipping my phone around!.

Emotiscope's wood plate is actually symmetrical, so it can be installed backwards with the blank side out if anyone wants a more minimalist look!.
@lixielabs This is awesome. You need a cool logo to go in place of the typography, like a stylized LXL or something.

I spent a near-daily year designing the greatest music visualizer I possibly could, and it just went on sale again! โก๏ธ.

Hey @Ascii211. It's three years later now, but can you point me to any names for this phenomena or studies about it? It's still fascinating me. ๐คฏ.

RT @lixielabs: I need a breadboard that fits all the newer microcontroller dev boards that are gigantic like the ESP32 Dev Kit boards or FPโฆ.

3D printers make great slider shots as long as you turn them off before the Z axis starts to auto-home too! ๐จ. Also, did you know that the back of your Emotiscope's black diffuser is glossy? Flip it around if you like it more than the matte side!

Fun fact: none of the lighting cues or camera pans are "real" in this one!. I played the song into Emotiscope 11 times in 11 takes. One with the light here, one over there, one with two lights, and so forth. Since Emotiscope creates shows very reliably, you can't see the seams!.
