I like thinking and blogging [1] about electronic circuits despite lack of formal education. It being a hobby, I must concede that my involvement and proficiency remain well below industry standard. [1] https://blog.georgovassili

Unfortunately the installation experience on Android has been getting worse. In the beginning a website could prompt the user for installing the app offline, then it became a semi-heuristic thing when the browser would trigger that even, no

ICA can isolate individual signals from a mix. The demo mixes three radio recordings together and then extracts them again.

As I played around with the simulator I found that higher input voltages lead to better efficiency. My intuition is that as the first BC provides a higher input voltage to the 2nd BC, the 2nd BC operates with a higher efficiency.

Thank you. That's exactly the case.

The first circuit is a generic block diagram serving as a placeholder. All following circuits are implementations. It wasn't run in the simulator nor were efficiency numbers recorded for it.

Isn't that a charge pump? If so, then yes, but it didn't perform well enough to be included.

Interesting conclusion: the author once backed up old climate data, but won't do it again and asks that someone else does it this time.

Makes sense, thank you!

Can someone explain why this doesn't distort the signal? Eg. with all these capacitors one might think it would filter out higher frequencies?

If this worked it would be great! I tried to sign up, but it requires way too much upfront manual data entry - would be great if it parsed a CV document or read data from Linkedin. At this stage I don't want to continue testing it beca

1. Your VP sees something in the guy that you don't and vice versa. I think it'd help if you both agreed on a shared understanding of the requirements for the role and then each explained your views how the new hire fits that role

Dan North lives from speaking at conferences, corporate events and tutoring classes, so coming up with novel, memorable terms is his trade mark. I attended such a class ("software, faster" [2] or something like that) around 2016.
