I am sure that plenty of people would be interested in your project. Many people do not understand electronics enough to undertake such a project on their own, even if the details of such a project are rather simple.
As for the controller, I think most people like the ability to change the spectral output and theretofore aesthetic of the tank. A small PIC or AVR would easily do the trick for spectral options and dimming on a schedule.
bean, thank you for the response, yes the electronics can be tricky and analyzing the components (the spec sheets tell nothing of their electronic characteristics) to do the calculations was fun to say the least working the heat dissipation was another surprise but it is doable and it can be done for around the comparable metal halide and actinic bulbs set up (be it vho or compact florescent) cost.
this is still in the infancy stage for me, and I am setting up a circuit board layout and blue print so that when I do the other side I can just drop the components into the holes where the silk screen says and then solder them in. I have found a place that will make the board for me, double sided, silk screen, and solder masked, for around $20 so hopefully soon I will be able to give you guys a drawing and a web page and say send them this and they will send you back the board you need. with that said the total assembly time to make the light was only two hours and that was drilling the heat sink mounting the leds, and soldering the components together along with trimming the amperage for each one.
the dimming controller is a great idea and a simple one also but the way I see it, it will be something I will tackle after I get the design simplified and very easy for some one with very little electronic back ground to make.
with that said it is very easy to get the light out put you want by just changing the main resistor in the set up, takes about 60 seconds to change all 9 out on my system as it sets right now.
but that is also what the solaris is all about for people that want that and everything else the solaris gives which is a lot in my opinion they can always bite the bullet and buy a unit. I just can not see paying the price for the cycle and all the other benefits when I tend to buy the same bulbs every time and have kept the same color balance and light cycle for the last 25 years that I have kept reefs, for me it was just over kill. I make about $300 a month from selling frags from my tank they grow so fast, so for me to "need" the moonlight phases and all just seems too much (I know I am going to get flamed for that one) my tank produces everything from aros to brains both my brains drop 10-15 buttons a month I put them in my grow out tank and then sell them when they are big enough.
anyway I am way off track sorry, I am working on making the electronics easy for even the most basic of diy project people
just please give me some time to get there.
thanks again for your input.
