I want to make necklaces out of small plastic toys such as jacks, toy
soldiers, etc.

I read a little bit about how to melt aluminum in an easy backyard
foundry thing (I don't know the terms), and I was wondering would it
be easier (or possible) to dip the object into some molten aluminum,
pewter, or something to make a nice metal coating, or if I need to
make a sand casting. The thing is I don't have anything to grind off
the excess with if I mold it.

Plastic melts at a much lower temperature than aluminum.

If you live close to a community college, take some basic shop classes.
Check if there's one specifically for artists.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
