Semi-OT: Free samples for the electrically inclined

I have no affiliation with this company, I just thought it was
something neat and it doesn't look like a scam.

Someone sent me this link thinking I use stuff like this, but I don't
have much of a use for these. However, I figured someone in these
groups might find them interesting.
