Rotary DECT phone

phones

[Al] sent us over to his Rotary DECT phone project, and we think its pretty cool. He’s attending Hacking At Random, and as usual, there will be a DECT network there. Rather than having a normal DECT handset like everyone else, [Al] wanted something a little homier. He chose to combine the guts of the DECT handset into an old rotary phone. He had to use an Arduino to convert the rotary output to someting the DECT handset could use. There’s plenty more information as well as some source code on the project page.

Making a tilt-shift lens

tilt

[Bhautik] is on version 2 of his tilt-shift lens, and wrote in to share what he has learned. Some aspects of the design on version 1 made it a bit quirky to use. You had to hold the lens in place, manually adjusting the focus. This meant that no two shots were the same. Since [Bhautik] wanted to do time lapse with it, he needed to re design it. He kept it simple and cheap, around $22 total.  Version two takes a lot longer to setup for the shot, but the result is reproducible. This means he can make his tilt-shift time lapse videos.
