Lollapalooza for the fish and invertebrate festival.I found a cool way to kill your fish and shrimp:

Don't be disappointed, my friend. Your contribution is very important to the hobby.Haha, disappointment is a part of life.
Great project.I cant for the life of me get the LED controller to work with LED current limiters, But I did use your project for something else.
I use an awesome and very cheap LED light from aliexpress, it has 2 channels ( blue and UV and white and UV) the controller is terrible SO I used your controller with some mosfets to make my own schedule. Right now im testing it om my 1 gallon food container Pico that is still cycling that only houses a BTA:

I'm ordering some more esp32s to do the same for my limonade jar pico
Thank you. I'm working on it right now. This is a true all-in-one board. It only needs LEDs, a fan, and an NTC connected externally.Don't be disappointed, my friend. Your contribution is very important to the hobby.
Here in Brazil, we are having a lot of difficulties with importing.
If you make something modular that a layperson only needs to connect the wires and put it up for sale, it would be much easier to reach a much larger audience.
I know the basics of electronics, but when it comes to programming, I'm the copy-and-paste type...
But congratulations on your initiative, and don't get discouraged, you're certainly helping a lot of people.

Testei minha placa de circuito impresso/driver. Aqui estão os dados a 100 W, sob convecção natural (sem ventoinha), com temperatura ambiente de 24 °C, seis canais, cada um a 23,5 V e 0,7 A. A temperatura máxima da superfície da placa de circuito impresso estabiliza em torno de 80 °C. Com um leve resfriamento por ar forçado, ela pode ser reduzida para 54 °C.

Thank you for your support and for sharing your 50-year journey in the hobby. It's an honor to hear from a true veteran.I would love to test this in a terrarium set up. I have kept everything under the sun. Freshwater for around 50 years Arachnids for around 40 years. Saltwater for around 20 years. And over the last 10 years I have gotten into terrariums and some rarer plants.
I was happy to see this when I did as I was looking for an app with better/easier usage with a TC421. Plus I've been just searching for a different unit that could achieve what this has but better or more updated.
Thank you for your work and dedication.![]()
Of course, it can be supported.Would this PCB work with your controller?
