In terms of what I could earn by doing overtime at work, these devices don't make me any real money (and one of the models doesn't really earn me anything). But I'd rather do what I enjoy in my own time than do more of my day job.

Yes, and meet a happy person because of it.

My nightmare may actually be too many requests all at once. That isn't happening, so I'm happy to assemble one every now and again. Anyway, it's nice to know I can send out another one quickly if someone has trouble with theirs, as long as they agree to send any troublesome one back.

I dunno about your topic though, seems I'm meeting happier people.
