Parts and tools list for BME 51B Spring 2018

I’ve put together the parts list for the second half of the Applied Electronics course for this year (Spring 2018).

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, and just did a copy-and-paste to this blog page.  The formatting is terrible, and I might come back later to fix it.  It is really a shame that doesn’t have decent table-editing capability.
