You used to see Altoids tins used for project boxes for everything imaginable, but since 3D printers became widespread, it’s extremely rare to see the tins used for projects anymore. I know a a lot of people in the makerspace who would only buy Altoids to use the tins afterward for their projects. Now, they just 3D print a custom case.
What is altoid?
Its a type of breathmint that comes in a little tin can.
I had a little op-amp headphone amplifier I built in one because my mini disc player was really, really quiet. Couple LM386’s, iirc.
I had a little self made amp as well. That thing could go loud, you had to be careful (I messed up the resistor or knob that controlled the volume and instead used the computer settings because $ to order another part). 30% was very loud 😀
