No matter how crude, home brew always has a better buzz.
Views on climate
Based on the majority of scientific consensus, both global warming & sea acidification is a reality and a direct result of human activity. It affects us all and will do so in more profound ways than any global economic crisis. If we are to mitigate some of the harm it will cause, we must not only understand the sources of green house gas emissions, but also change how we invest our money, buy products, do business and vote politically.
Interferometer Downconverter Components
Still finalising the circuit diagrams but here are some of the core component datasheets I am reviewing to include in the design.
