Parts and tools list for BME 51A Winter 2019

I put together the parts list for the first half of the Applied Electronics course for this year (Winter 2019) a few months ago, but never got around to posting it.  I’ll do the parts list for the second half soon—doing it too soon is counter-productive, as links go stale, either because the vendor runs out of stock or the part reaches end of life.

This year I created the list initially using Google Sheets for ease of communicating it to the lab staff who have to do the ordering.  I tried to do a simple copy-and-paste to this blog page, but GoogleSheets doesn’t provide the HTML on a copy, so I had to export the HTML, edit it, and then paste it into WordPress.

I did not add sales taxes for shipments that did not already include them, though UC has to pay the sales tax, even if the vendor doesn’t collect it.  That will raise the prices by about 8%.
