I agree that a PCB would be great, but for my purposes a breadboard would work just fine. Also, I edited one of my previous posts. I could do a 6v version, but that would add 3 more components.
I realize that you could get "the real thing" for $35, but $15 is a fair bit of money to some people like myself. I get $20 a week, so that extra $15 would just add another week of saving up. Instead, there is another option that may be heavier and larger, but some people don't mind that.
