As well as the time, expense and effort it took you to develop the S/UV interface you have certainly given a lot more time here and in many other threads involving solar and UV measurements.

.

I started it just by reading this simple documents from Charles G. Wright:

I remember that I have spend all the summer doing experiments. My garden seemed a laboratory, full of many types of solar cells, Arduino's for everywhere. Countless hours of work, but I like to do it... My process of doing things is by experimentation, and the best tools I have are patience and persistence.

So I completely understand, Werk_AG, why you will withdraw this interface but I want you to know how much I, and I am sure others too, appreciate the considerable work you have done in developing and supporting this interface - which is only part of a truly amazing project. Thank you!!

It will not be completely withdrawn, but from now one it only be available to veteran WeatherDuino users (I already have added a even more clear statement about this). The same will apply to the Soil / Leaf interface, which setup is a lot more complex, specially the mapping of the sensors on the software, something a experienced user will do alone, in a couple of hours.

Thank you Allan, I think your post is a proof of what I'm thinking right now about this matter. As stated :

"With the Solar / UV interface you can build a reasonable solar radiation sensor, but don't expect that this task will be just a matter of connecting the parts and that's all. You may need to spend a considerable amount of time and effort to calibrate it."

My first computer was the Spectrum ZX81 (36 years ago), I bought it not fully assembled, but as a kit (less expensive). At the time I was 18 years old, I took two weeks to fully assemble it, carefully checking part by part, I could not risk doing something wrong because I would not have the money to buy another. At the first time I powered it, it worked. I still have the ZX81, and it still works, for me its a jewellery.

I'm not an engineer, I had never finished my studies at the University, had to start to work early. Despite I work with complex and very expensive electronic equipment's my professional life isn't in any way related to electronics or computers.
For me all this is a hobby, that I do to keep learning and for pleasure, not a job.
I'm aware that by exposing publicly my humble work, I'm risking that it be judged by lots of people, which are experts in electronics and or programming. That its natural and good. What its a pity is that most of the times, aren't presented easy to build, fully tested and functional alternatives (even if only just prototypes). As said, exposing our work its risky. Always there is someone which knows more than us.

I have a cousin who was a reputed investigator in maths, he have worked for University's all over the world, as EUA, Japan, Germany, etc, he used to tell me:
During my life I met lots of investigators far better than me, however they don't had the same success as me, mainly because they are much reluctant about publishing their work, always afraid of the judgement of their counterparts. I'm not afraid of doing it.

Sorry, for this off topic talk.
