Live Stream to YouTube by Pointing a Box and Pressing a Button

YouTube has the ability to do live streaming, but [Tinkernut] felt that the process could be much more straightforward. From this desire to streamline was born the Raspberry Pi based YouTube live streaming camera. It consists of a Raspberry Pi with some supporting hardware and it has one job: to make live streaming as simple as pointing a box and pressing a button. The hardware is mostly off-the-shelf, and once all the configuration is done the unit provides a simple touchscreen based interface to preview, broadcast live, and shut down. The only thing missing is a 3D printed enclosure, which …read more

Filaween 2.0 is Go

[Thomas Sanladerer] is at it again: testing all of the 3D-printer filaments that are fit to print (with). And this year, he’s got a new and improved testing methodology — video embedded below. And have a search for “filaween2” to see what he’s reviewed so far. There’s some sexy filaments in there.

We really love the brand-new impact strength test, where a hammer is swung on a pivot (3D printed, natch), breaks through the part under test, and swings back up to a measurable height. The difference in swing height reflects the amount of energy required to break the test …read more

The Elements Converge for ±.002 in Tolerance

What can be accomplished with just a torch and compressed air? We can think of many things, but bringing a 17-foot-long marine shaft into ±.002 in tolerance was not on our list.

Heat straightening (PDF) utilizes an oxy-acetylene flame that is used to quickly heat a small section of a workpiece. As the metal cools, it contracts more than it expanded when heated, resulting in a changed volume. With skill, any distortions on a shaft can theoretically be straightened out with enough time (and oxy-acetylene). Heat straightening is commonly applied to steel but works on nickel, copper, brass and aluminum …read more
