question based on a dim memory and some updates

[Elton A Sanders]

Are you talking about the epoxy cubes with wires 
sticking out the top that look like they were 
molded in an ice cube tray? Cant remember what 
they were called but they did lots of things.
A useful thing would be a socket to take power 
tool batteries with or with out a regulator to 12v or 5v.
