We all love our cordless drills, here is what I think is the first collection of collections on instructables. It both tells how to use the drill for more than just drilling, but how to give it some TLC when the batteries fail.
As an aside do you like or hate the idea of collections of collections, you cannot comment on a collection ( or guide ) but you can send me a message through instructables. I hate wildly incomplete guides, like one on the Arduino with only 5 of the tons of instructables included. I think you will find this one quite complete. However since it is a guide to guides it was natural that it did not have many entries and I needed to pad it out to 5 to get it published. More recently I noticed a collection of collection of collections, see: https://www.instructables.com/id/collection-of-collection-of-collections/
