This is a modernization effort on https://forum.pfsense.org/index.php?topic=115672.0
The list of dependencies has grown somewhat. Browsing through http://pkg.freebsd.org/FreeBSD:11:amd64/release_1/All/
you will need to pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/release_1/All/... the following:
Welcome to the descent into madness that is Excel units.
xlsxwriter has this lovely nugget that, unless you really care about exact column widths, you probably never had the urge to look up:
# Convert column width from user units to character width.
# For Calabri 11.
max_digit_width = 7
This is a handful of sessions to learn various subjects in electronics, including component selection, mains safety, a little bit of embedded design and programming, prototyping, and CAD. It will be done by making a simple clock with easy-to-manipulate through-hole parts.
These sessions are to be run separately from Ryan's KiCad session because this has a different focus - electronics basics - and uses a different CAD program, Eagle, because it's what I'm familiar with. All software used is free.
Attendees are to bring their laptop, note-taking material, and a calculator if they have one. (Math will not exceed the elementary school level.) Grid paper is recommended but not necessary. Bring $20.00 in total (not per session) to cover the cost of parts. If the attendee elects to purchase fabrication, that cost will be separate.
In the lab we will be using oscilloscopes, power supplies, multimeters and prototyping parts brought in for this project.
