Super Capacitor in solar power supply - a few queries

Sydney-Floyd's picture

I intend to build a remote 'weather station'

The station will:

  • Be completley independant of any external power, ie, it will produce its own power via solar cell(s)
  • Measure temperature only
  • Transmit its finding over an RF link to an indoors reciever

Instead of using a rechargeable battery supply with charger circuit, i have decided to use a 35F, 2.7V super capacitor to smooth and store power.

Well, I had some fun in the attachment. I would take a sheet of flexible circut stuff, and charge my 24Joule Capacitor bank. i would then short out the points between the plate and the wire, vaporizing the copper at the point, creating a black spot. In the attachment, I spelled KL!, mostly because I diddnt have that much to mess with :)

 I was thinking of doing LMR next :)

How much would you pay for a baseball cap like this?

Personally I think it's a bit expensive (zazzle).

Any thoughts about the design? What changes/aditions would make it worth the 20 USD?

Besides of course an i-pocket in the rear.
