Just wanted to say thanks for this thorough teardown! I am looking for ways to quiet my noisy evaporative humidifier and was curious how the Conway worked.

Thank you for your comments. I am glad to hear that you found this project helpful for your purposes.

I have also developed an experimental replacement main PCB for this unit, based on the ESP32 since the publishing of this project. Once the board is tested and software written, it will be open sourced as well.

In the meantime, I have determined that the original board only uses PWM duty cycles between 25-85%. I believe this range may be expandable on the low end, at the very least.

Awesome!

I'll echo my thanks. I've passively thought about replacing the control board with an ESP8266 or ESP32, and this teardown as valuable in confirming such a thing would be possible, albeit likely a bit beyond my skill level. If you do open source a design, I'd be very curious to look at it.

Design has been open sourced (quite late, sorry about that!). Unfortunately I have not had time to finish a firmware for this device.
