How-To:  Make a piece of translucent concrete

How-To: Make a piece of translucent concrete

This tutorial by Instructables user nepheron shows you how to embed ordered optical fibers in cast cement to produce a small lump of concrete that will transmit light. It’s based on Litracon, a commercial architectural material that, I believe, invented the concept. I’ve been considering a very similar “cast your own translucent cinder-block” type tutorial for the Make: Projects series for some time.

How-To:  Elegantly simple squirrel-proof bird feeder

How-To: Elegantly simple squirrel-proof bird feeder

I love this bird-feeder tutorial from Instructables user me13lake. It’s not flashy (indeed, with a title like “Small simple horizontally mounted squirrel resistant/proof bird feeder that requires no specialist tools to make,” I’m guessing it was written by a scientist or engineer) but it’s well thought-out, easy and inexpensive to make, and it looks like it would work very well. The clear squirrel-guard rotates freely so they can’t get a grip, and can be made from a 2-liter plastic bottle. Or you could try cutting one from a glass bottle.
