🎓 Dr. Freemo :jpf: 🇳🇱 (freemo@qoto.org)'s status on Thursday, 29-Aug-2019 10:42:03 UTC 🎓 Dr. Freemo :jpf: 🇳🇱 Recently uploaded a copy of a book I was writing to help teach RF/AC circuit analysis. I never did finish it but the first few chapters I wrote has some really useful explanations. Anyone trying to learn electronics should take a look.

🎓 Dr. Freemo :jpf: 🇳🇱 (freemo@qoto.org)'s status on Thursday, 29-Aug-2019 02:26:33 UTC 🎓 Dr. Freemo :jpf: 🇳🇱 Now that the #QOTO Discourse server is fully working, including the math rendering, I can start adding some content to it.
For my first post I wanted to share a tutorial I wrote on how to do frequency-domain nodal analysis on electronic circuits.

🎓 Dr. Freemo :jpf: 🇳🇱 (freemo@qoto.org)'s status on Friday, 19-Jul-2019 11:22:51 UTC 🎓 Dr. Freemo :jpf: 🇳🇱 So I recently got a few thousand boards printed up for my protoboard design. Tested them on a few circuits and im amazed how well they work. I'm writing the datasheet now and we will begin selling on digikey, mouser, and many other big names soon.
In the meantime any EE people out there want a free board? We are going to hand out a few hundred for free to get people interested.
Here are some past posts I made about it for some background info. I've also attached an image of the final boards.
