I immediately thought of this one. Perhaps more useful to the 99% of us who dont work with SMD. I am sure the 'detector' would provide amusement to a few people.

I'm pretty sure more than 1% of electrical engineers have worked with SMD - they're tough to avoid these days, unless you are strictly doing microelectronics, or a power engineer bolting things together with bus bars.

We are not all electrical engineers.

You won't even be a hobbyist for much longer, unless you make your peace with SMD.

Relax. It's fun. Assimilate.

Im finding SMD easier than through hole. Reflow the board and your soldering is done in one step.

And PCB production is so cheap and fast now.
