#94 - Switching Regulator Lab Part 2 - Typical Application Circuit into KiCad
As the name says, we're working on getting the typical application circuit from the datasheet for the specific chip we picked out and getting it into KiCad so we can potentially use it in other circuits. For this lab though, we'll just use it as is and ultimately build the PCB from it.
The point here is that if you can learn to use the circuit provided already by the designers then you you can begin to access a much larger world of components. ... https://www.youtube.com/watch?v=QkrCryk-tD8
A look at the latest hand-made CNC. These newer versions are all capable of cutting metal (aluminum and steel so far) and retaining good tolerances. This model has a few more elements to add and screws to tighten, but as soon as that's done I'll get another video out showing it in action.

I also wanted to give recognition to Dave Jones and the EEVblog since I noticed while editing it was paused on the screen in the back the whole time. If you're into electronics you absolutely should check that out. Doesn't everyone crank the EEVblog while working in the shop??

This is the first "in the field" ringing issue that I've had the opportunity to observe and mess with.
Most addressable LED schematics have a resistor added in series with the data line, but I wanted to see what was actually happening and how various resistors would change the signal. The inductor was just an impromptu decision to practice some component theory and see how well I could sculpt a signal. For me, I think this turned out to be quite interesting.

This is a fairly old video I had laying around. Sorry for the lack of commentary. Also I normally I don't like just drop music over the top but it felt better than dead air.
Some of the key point here are getting the resin jammed deep into the delammed area and clamping well. Protect the board thoroughly because resin goes everywhere, and have some good tools to sand away the excess when dried.
