Less then a month to go

On december 21 it's again time to set up for your next solargraph. So you have 4 weeks to prepare making your own pinhole camera. DIY Instruction are available via my blog link here.

I will be preparing my next ones as well ... :) and it's not about the beer... it's about the 50cl cans.

On december 21, I will remove my installed pinhole camera's which are out since June 21. It will be my first results of the period June-December. All my previous Solargraph are made in the period Dec-June.  I'm curious about the result and what would be the difference between the periods.
