Hello lads!, I need help for a personal project, I explain myself:
- I wondered how much sollar energy I could harvest in the roofs of my house to see if that would be a good investment (I live in Norway, and since the sun is quite peculiar here, I want some empirical results.
-after much thinking, i got the folowing idea: I have a small USB keyboard with the numbers and math symbols, some small solar powered mini lamps for the garden and some random components from a broken radio, and of course , a paper clip
well, My idea is the little solar cell will charge the capacitor, and when this is full, would send the signal to the center pin of the transistor and this will allow the 2 conectors of the keyboardto be en contact, which would send a digit to my computer. in this way, I would know how much energy each digit represents, and I can program a software that monitors all the digits (Up to 10 solar cells in different parts of the roof) each second and records the data and show it in a graph etc..
well the software writing aint the problem, the electronics are, I Am as new to this as I can be, so here is how far I got.
1-Solar cell
2-capacitor
3-transistor
4-both sides of the keyboard plates (when this sides get in contact a digit is sendt to the computer)
This is a test, as soon as i fin how to make it work, Ill make all the proves
Questions:
Where do I connect the other end of the power cell?
or basically, how can I make this work?, things I shoud know like witch capacitor/transistor should I use etc... Im really lost.
Thanks of forehand guys!
