My blah...
I like how you put the effort to do this thing rather than just toss them "there" like I do. I have a big travel bag full of stuff but random.
What I wanted to ask is: how do you buy these items? from aliexpress and ebay? do you buy when you need something or have a collection to collect?
Finally, this partsbox service is not free thus for me, if I ever made a stock control system, that would be an excel sheet.
I generally only purchase components from Mouser.
Sometimes I will get passives from Ali, but never actives. I had a bad experience once.
I always buy more than I need unless they are a particularly expensive component.
There is a free hobbyist plan at partsbox.io.
You need to scroll down the page past the paid plans.
The free plan limitations are not too bad. I can live with them. Cannot remember the exact limitations now...
