As i13 mentioned, one can 'watch' a thread but as I understand it, a thread one initiates or contributes to is automatically 'watched'. What also needs done is in the user profile is a checkbox to receive emails and notices, which obviously would need checked. Another method is to periodically check the website and look at the 'alert' icon (shape of a bell) located on the right side of the website 'ribbon'; also to the right of the website username.Sorry it's taken me so long to reply. (Is it possible to get an email reminder when someone responds to a post?)
What I've been thinking about is running everything off a 12v battery. There are cheap solar controllers that are designed to charge 12V batteries, with "street light" control, like ...
... series of distribution points at 1.2 and 3.6 volts, as the lights seem to come mainly in single or triple 1.2v series, and multiples of 1.5v for the common non-rechargeable battery-powered lights which are cheap and readily available. The existing lights I would rewire to attach to those distributions. ...
Using 12 volt is all right but I would avoid any fractional voltage division as mentioned in a previous post doing so creates a loss of efficiency. Loss of efficiency really needs seriously avoided in a low power application which I think what you are attempting is. One typically would also avoid passive components as much as possible; resistors for example.
I looked at the charger/controller, noticed that it did not specify compatible battery types and solar arrays; so a bit lacking in specifications in my opinion. Jaycar I see does list units which are not too much more expensive that would I think be a better fit.
I think at this point it would help if you could indicate a quantity of lamps and one or two types you are considering. A solar panel too if you have thought about it any. Also considering I'm in the 'other' hemisphere, typical swing of daylight hours between summer and winter.
Somewhat beside the point but I have about 20 solar lights that I am getting ready to convert for Christmas. Plan is to convert them to 12 Volt WS2811s.
