Melting Cans With The Mini Metal Foundry

|

For as long as I can remember, I've been intrigued by the idea of melting metal and making things with it. The problem has always been that it was out of reach or required really expensive equipment.

In this project I experimented with 10 different prototypes, to develop a reusable backyard foundry that melts aluminum soda cans easily and safely. I tested different refractory recipes, different containers, different setting for blowing air, and different types of makeshift crucibles.

I tried various ratios of portland cement, sand, perlite, plaster of paris, water, and even kitty litter. For containers, I experimented with clay pots, plastic buckets, no container, cinderblocks, and a galvanized steel pail.

The dark side of electronic waste recycling

Jim Puckett got the messages from his “little lie detectors.” They were small devices, not much bigger than a deck of cards. Being GPS trackers, they also didn’t look much like actual lie detectors. For years, as the head of the Basel Action Network, Puckett and his team have been throwing them in the trash.

Electronics can be hazardous when disposed of improperly, and the Basel Action Network, or BAN, investigates the underground world of the e-waste trade. The nonprofit group secretly embeds trackers in discarded devices, then hands them to recyclers to see where they end up, exposing bad practices in the process. After dropping bugged LCD monitors in Oregon, they followed along as the trackers traced a circuitous route through the summer of 2015 and into the fall.
