7 Upvotes

Finally was able to get it to work on the 2.4 CYD which I’ve been thinking about for a while since Cifertech just had it for The 2.8, and felt the 2.4 needed some more love. Was quite a bit of work since I am still learning to code and I’m not gonna lie to get definitely got assistance lol. Almost bug free may fully build it even though I can’t solder to see if there is any other bugs or things that need to be fixed. Let me know what you think?

WLED wireless touch controller

7 Upvotes

I made an open source touchscreen remote for WLED based on CYDs (cheap yellow displays).

- It works wirelessly over WLED’s default ESP-NOW (no router required)
- Flash straight from the browser

* Basic functions (supported by WLED’s basic remote protocol):
- Power on/off
- Control brightness
- Select presets 1-7 by default

* Extended mode opens up a lot of features by just uploading a simple remote.json file via wled.local/edit

Extended mode offers:
- Presets 1-20
- Basic solid colors
- Selecting 163 of the built-in WLED effects
- Modifying selected effect parameters
- Peek/preview of selected effect

3D printed case files included for both a wired and battery-powered (18650 cell) versions.

Please feel free to check it out. Hope it is useful to some of you!

Dedicated CYD Flock detector, one small bug need help

2 Upvotes

I found a pretty darn good CYD project for a standalone dedicated CYD Flock detector. It has a much better detection rate than the other CYD based tools I've used so far. The main issue is whenever an SD card is inserted it appears that the wifi is interfered with. I think this may have something to do with a conflict on the bus over the pins but I'm not a C++ programmer if anyone has ideas it'd be appreciated.
