All in One LED Controller/Dimmer/Driver Project

[Kampo]

Right now USB (pending the 3.0 driver support) - though WiFi would also be possible. There is no PWM input.

nice. will be watching this project, you going to open source the esp32 side? or keeping that inhouse?

I think if you can, go fan less. Less to fail, and fans suck in so much crap from the air and deposit it on the board making more problems.

Open source the ESP, main MCU, backend as well. GPL or AGPL.

With the power levels (8-15W) it’s possible though tight. I’m trying some thermal material to mount the board to the case bottom but it’s still not a lot of thermal area. Fan is under software control so we can adjust usage

Looks cool! Did you already find a fan which does not make too much noise?

What is your preferred way of mounting this "box"? Directly in the lamp or somewhere in the stand?

Its a standard 25mm fan, looking at this tiny guy:

Splurge a bit..
https://www.digikey.com/product-detail/en/sunon-fans/MF25100V2-1000U-A99/259-1831-ND/7805270
Much quieter and same CFM...
10db is below hearing..This is 16.. One posted is 30db..
Alternate..

Oddly draws more power and faster rpm than $11 one..
Obviously you could lower the voltage on the one ..but.

Noiseless but only 1.2CFM...

Different between 6.7mm depth and 10mm. I do have space for the 10mm of course.

On a side note, I hit on a brain wave of packing a smaller driver array (4-6ch) + a led panel in the same exact case, using a similar end cap fan cooling solution. Easy since the bottom panel is removable - that becomes the splash screen by using acrylic or diffuser material. More on that elsewhere

 

[theatrus]

Still missing some parts, but initial build is ready.

I was wondering about that end cap comment you made earlier but now I see it! I like this idea.

I need better screws - the included ones are junk for this purpose

Following along. One of the main reasons I have held off on DIY LED's is the wiring headache.

Do you already have a functional prototype for testing?

Prototype is undergoing testing and hand-modification for improved versions

Errata so far:

- Fan can't be PWMed
- Over the air upgrade SPI flash can't be used as connected
- Power supply compensation network layout and part error

Nothing unexpected really

 

[Jânio Silva]

hello how are you test them? Already have a board for the public test?

 

[theatrus]

With some other delays I don't have updates yet, but soon!

 

[jvswan]

Wondering if there’s been any more progress on this design?

I've been focusing on building this out with some LEDs in a complete package, so not yet. The original design however does work, but is due for a round of simplification and just letting the ESP32 run the PWM.

 

[TDEcoral]

Still working on this? I'm curious why you think it would be better to use the ESP32 for PWM instead.
