It took Husband and I only an hour to turn the vintage minnow bucket I inherited from my father into a unique charging station.
Step 1Go Shopping!
Necessaries List: Two 3/8" rubber grommets, one 34" rubber grommet, one power squid, one replacement plug (to replace the one you'll cut off the power squid), power drill, metal cutting drill bit and mandrel, WD40, Band-Aids (just in case). Vintage minnow buckets are available on EBay, for about $15. (Have you seen the new soul-less plastic ones? I guess they're useful...)
There's one thing that I wish I'd done differently. I wish I'd left the flip up lid in tact. The small hole I made in the flip up lid proved difficult to get some charger jacks through. If I could do over, I'd just drop the jacks into the bucket, and then fish (pun not intended) the one I needed for each device. Hindsight and all that.
Good luck!
This Instructable is very well illustrated and the idea of using a bin/bucket shape is design oriented. In fact, Rotaliana, an Italian firm specialized in lighting design, produces a very similar object since 2005. It is called Multipot and costs 150 €!

This object has recently won "Compasso d'oro", an italian award for industrial design. You are on the good way!
