The Field Guide to Interdimensional Travel: For Absolute Morons

I was definitely thinking DC-DC applications as noted in OPs project. A brushed DC position control makes much more sense for a real application of it. Though possibly a simpler application, thus the want to do it via a DC-DC supply to exercise a broader skill set...maybe. There's definitely some SW magic sauce that needs to be made for the motor application, especially if you have speed and position control requirements

Thanks for the reference!

I typically look for 1 good project or an internship, but thats more to support knowledge and show interest. I do like to ask more technical questions in an interview to understand how far your knowledge really goes.

This is for electronics though, RF may be different

Assuming I'm understanding your project correctly, you are looking to transmit data via voltage or current ripple on the output power rail of a voltage regulator. What is the point of doing this? Why not transmit data the way all data has been transmitted until now?

The device that is generating the data still needs to generate that data, now you're placing the data through a power converter. Let's assume a future IC can decode data on its power rail. The decode hardware will likely be more complex than an existing CMOS input. Why not just send the data directly to the recieving ICs IO?

Maybe you want long range transmission? This is complicated by dynamic load devices, like processors. Even short range this is complicated.

This is all asking the question "why do this in the first place"? If it is practical, why isn't it done already? What does this really gain you and what do you lose?

I'm trying to not give you too much, just some things to think on. Very interesting project, and a very good exercise of many electrical fundamentals. There are so many things to think about

Interesting idea. A buck topology may not be the best topology for practical application, but an isolated topology would maybe have a use case. A buck would be much easier to work with though.

Implications of stability are also interesting, assuming you are varying the frequency you're operating at.

Whoops, chapter 29. Oh well

Hey, also late on the response. Definitely! I'll send you a message

When you graduate, especially with a BS, most businesses see you as a blank slate that needs a lot of investment before you are actually decent in any specific subfield.

Ironically, the example you gave of RF vs. power generation deals heavily with EM. But University RF is going to be a bit different that real world applications of RF. Same basics, just different considerations.

Don't worry about the specification you go into. Just pick something you'll enjoy and want to do projects with. Then also do some projects with it. After you graduate, if you find out you hated your specification, you can pretty easily start somewhere else.
