this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....

Hi All,
Like the design thinking of this, although an older topic I did manage to get me one of these dishes. After taking it apart, I have one question that came to mind. Is the ventilation in the dish enough for the humity sensor? Is there any experience with that after running this sensor for a while?
Thx
Ralph
Hello, yes I think it's enough, in fact there's much more ventilation than in many commercial sensors which only have a small hole. But it's a good test to make, I'll try to compare to a sensor out of it's enclosure to see if there's significant difference or delay.

Just one of many ideas, the possibilties are endless. I'de always go for RGB leds over just white, allows for more customisation while able to still give you the same white as the white leds.
... unless, as in my use case, colors are not needed.
I'm too stingy to pay for the unused dry powder!
The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle.
In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V.
Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work.
Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).
