I'd be interested in presenting a pair of related workshops, one on "Things that go wrong with projects", basically covering how to keep clear of pesky time waster problems.


The other would be an EMI/EMC workshop.  If you're going to sell your project, and you are using a clock faster than 9 kHz, you will need to face FCC part 15 compliance.
It's not really all that hard to pass, with a two layer PCB, and no bucket of magic ferrites, IF you know and apply some simple principles.

Sorry for the late reply - Thank you David for offering your expertise! When would you like to do these and what do you need to make them happen? The next 2-3 Saturdays we have Arduino workshops planned, but I would also like to see a bit more activity on weekday evenings.

Were you thinking of doing them back-to-back in the same day? The first sounds like it could have a much broader audience than the 2nd.

Thanks!
Lizz

I would definitely be interested in the EMI/EMC workshop! I've got my Ott & Johnson books, but want to learn more!

Me too. I've taken devices through compliance testing but would love to hear other's experience.

Another good topic would be ESD protection

I can speak to ESD as well.

I could probably fill a day or more on each, but I'd want some prep time.

There are so many things to cover in a 'what can go wrong ' workshop. EMI and ESD seem simpler by comparison.

For any project that you hope to sell as a complete device, you will need to deal with some sort of EMC. It is actually pretty easy to pass FCC part 15 or CE, even with two layer boards and no 'prayer beads', if you do your layout properly.

Project problems always start with power, and cover bypassing, unterminated inputs, high impedance inputs where not actually needed, surge current demands, crystal/clock problems... etc.
