Visit to base48 hackerspace in Brno after the first day of Maker Faire Brno. I went to Brno, Czech Republic for 4 days to give 4 workshops at Maker Faire Brno -- two workshops for teaching teachers, and two workshops for anyone at the Faire.

Problem: Your hackerspace is regularly flooded with TP-LINK 100-240v mains electricity to 5v USB chargers, but the AC power plug is of the North American NEMA type instead of the European Schuko/CEE-7 type. What to do?
Answer: Why not combine some into a huge array of chargers?
MacSimski's idea was to use a couple of filler metal welding rods and to solder the adapters onto that base. The rods can be used as a mains plug.
The result is the "Hack42 FestivalCharger": a 5v 10A powerbar which can simultaneously supply up to 33 devices with power (unless it trips the 16A breaker).
The welding rods are shielded with a PVC tube, which is capped with polymorph (protoplast).
The tube is further secured to the rods with a few sticks of hot glue, liberally applied in a few strategic locations.

The theme for the Hackerspace Hack42 New Year's Eve festivities was "Unplugged"; use as little electricity as possible. We had our faithful wood stove "De Draak" for heat, lots of candles and oil lamps for light, wind up gramophone player and a few boardgames for entertainment, and a gas stove for food.
