OK here is the spec:
- small : 20x10mm, 12vdc, 60mA, 2.17cfm
- medium : 40x20mm 12vdc, 140ma, 8.28cfm
What I'd like to do, is to be able to run the fan hook to the solar panel on regular inside incandescent light. Now the fan hooks to the solar panel, and needs direct bright sunlight to run. I think I need a voltage regulator and a capacitor (in micro farad) I'd like to have the fan running only when light on (no need to run at night), running at 1/2 of the 12V speed is fine to me.
So the question is: What capacitor and voltage regulator do I need? I heard that a dc to dc is needed, too.
I know electronics, but I cannot do the maths. I can solder, do breadboard, etc. but know nothing in technical match term.
I know that many capacitors exist, but I like to keep the whole thing under $10, solar panel included. Now the solar panel in retail cost 19.00 but Alibaba can sell it for $5 or maybe you know a US/Canada place to get cheep solar panels. Whole electronic thing excluding fan and solar panel: $3-5.
as told, MAYBE simple incandescent light will NOT be enough, so let think about putting it beside a windows, is it more realistic ?
