Why is it so hard to think these days ??

I was stuck on a problem for some days now. The problem arose when I was trying to fix the Capacitor values in the circuit, one of which was broken (more updates on it later). But it became so hard that I am now getting headache because everytime I come up with a model and well established idea it seems to slip.

Wrote some Pseudocode on it and trying to come up with a good design pattern with it but it still seems elusive.

Some working stills here, preparing for Numpy Arrays and a good object model in python. 

I used to do this all the time but never really cared to develop a portfolio, but it looks like id you do want a career you need to develop a portfolio.

That final draft of the matrix expansion that is going to fix this, the key element of thinking is still missing. Hopefully this will clear it up.
