But, to get on with it... this trick is so simple that you probably have already figured it out from the picture itself. To make a lot of electronics kits quickly, you use cups. Simply count out each of the parts into each of the cups. When you are done, you dump the entire cup into an anti-static bag.
This saves you the hassle from having to handle every bag for every new part, and remarkably cuts down the time it takes to assemble a kit by hand.
