Like the SM footprints, but I'm not sure I see the point of the resistor color code chart these days (If I do spec a through hole resistor, 99% of the time it'll be a 1%).

Thanks joe! Yeah, sadly through hole seems to be going away on the whole, but the color codes are still used often by some people, especially while breadboarding or prototyping. I actually referred to a prototype of the card myself while designing a board a few weeks ago:) so some people will likely find one side or the other more useful. Fortunately we've designed the card to be useful in a good variety engineering contexts!

Does "Set of Reference PCBs" mean four for $32.00?

edit: nevermind, I scrolled down far enough to find it.

This is lovely.

One gentle suggestion for version 2 is conversions between pico, nano, and micro farads, and the capacitor codes used for these. Because even though it's easy to do it's still nice when you're feeling cognitively challenged to have a cheet sheet.

I bought a set of these a few weeks ago.

Thanks Dan! Maybe if this one goes well I'll get to do a sequel :)

Not sure I understand - Vishay[1] MRS25 resistors are 1% and use a colour code. (http://www.vishay.com/docs/28724/mrs16m25.pdf)

They're generally pretty nice as resistors go. Do you spec better than that?

[1] I used these when they were Philips, which shows how long it is since I was doing this stuff.

I prefer using a multi-meter. That might be something to do with being colour-blind though.

It's fun, but I'm not sure what it's for as I can look up these things on the internets if I forget. Is this just an executive engineer gadget?
