Hi,

I have to start all over again as it looks like I fried my LMC6484 due to improper measuring while the Arduino was running. The values from yesterday where too low and so I tested the circuit which I still had on my breadboard and they looked much more logical.

Also the idea of the 3 capacitors un paralel was not good. I finally got my 3.3 uF capacitors and exchanged and it stabilized.

Well I still have holidays and so no problem. At least I have something to do.

saludos

Ooops, can happen. Few months ago i fried a nano Arduino in my focus controller while doing some modifications.

Hi,

Yes, " Sh...t happens " and I should have used a socket instead of Hot soldering the LMC6484 onto the board

Well makes me have more experience for the future :seesaw

Hi,

Went back to the bread boarded circuit and added a LED Bar for the visual identification while the SSM is working.

Video of 1 minute which crunches a real time video I took during 18 minutes.

Hi Paul,

Is that in real time and are you reading at an iteration rate of 1000 ? I am just starting and learning to program the Arduino so I still have a long way to go.

Hello,
no it's just a simulation before integration into my software, I find that the colors are more meaningful than the numbers.
blue very good
green ok
red useless

Thank Paul and yes you are right. My bar when many LED on is bad and few LED on good. At the beginning it is difficult to judge but with the time one gets used to it.

LED 1 and 2 I use them for signalizing Sun intensity

Led 1 Sun intensity and > 0.5 to <=1.0 then OK and ON else OFF
LED 2 blinks when Sun intensity > 1.0 abs so I know I have to adjust. It happened to me that I had to readjust because the adjustment the day before was again to high and as I see the sky today I think I have to readjust.

The little BPW34 was delivering yesterday up to 3 mA ( 3000 uA ) of current.

and then LED 3 to 10 are as following

LED 3 -----------< 1.0
LED 4 > 1.0 --- < 1.5
LED 5 > 1.5 --- < 2.0
LED 6 > 2.0 --- < 2.5
LED 7 > 2.5 --- < 3.0
LED 8 > 3.0 --- < 3.5
LED 9 > 3.5 --- < 4.0
LED 10 > 4.0 ----------

Hello everyone,

Paul, that's exactly what I would like to do, bargraph input & output super.
Your software is extra !!
Is it possible to have it?

Yes it is possible but this version is not completely ready yet ... and only Linux at the moment, although I am working on a port to Windows (would like to port it on OS/X as well, but no machine, and think my wife will throw me out if I buy yet another computer ;) )

I will let you know when it is ready and tested. The automatic trigger of video capture will (should) work wit Planetary Imager and FireCapture.

Regards,

Paul

thank you Paul,
I am with Win7 and do not know much in programming.
I'm waiting for your final version with pleasure.

Hello everyone,
thank you for this message, sorry not to have answered before, I'll try as soon as the sun will show.
In the south of France just December 5th and January 5th really good, if not only rain and clouds.

Hi All,
I am starting to tackle this project and build my own DIY SSM. Does everyone use one or would like to own one ?

I wonder what percentage of solar imagers actually use a SSM connected to FC or not connected to FC (FireCapture)?

I am thinking if someone could build it, would some of you be interested to buy it if it was a lot less expensive than the ones made by the mainstream company for 350 dollars/euros?

Thanks
Magnus

I have an SSM, used to use it connected to FC, rarely use it now, just gauge the seeing by eye and experience.

Thanks Mark,

That is very interesting. Sort of tallies with what I can tell from my own eyes. I am getting better with experience.
I will see if I can build one inexpensively, could be fun ?

Thanks
Magnus
