Self playing Bayan built nearly 22 years ago

The year is 1988, where a Russian engineer [Vladimir Demin] has combined a Bayan, or button accordion, with several (we lost count at about 96) solenoids. If that alone doesn’t blow your mind the computer, also hand built by [Vladimir], controls the whole process leaving the operator to only work the bellows. Putting truth to the fact in Soviet Russia, accordion plays you. We wish we could find some more information about the instrument, but curse our inability to read Russian. Alas check after the break for a shorter version of the video in the link above.

Solid ice beer caddy

brrrrr

[Rob] has made an astounding contribution in the effort to keep our libations chilled. Not content with merely refrigerating his cold ones, or even putting them in a cooler full of ice, he has built a beer caddy out of solid ice. Though it may look simple initially, you can see from his writeup that it actually took quite a few itterations to get it to freeze correctly, and then actually survive the process of removing the bottle placeholders. Ultimately, he found that glass bottles full of sand work best and you have to freeze the caddy in layers. Though he calls himself an impatient person, we’ve seen people who insisted on having their cold ones made frigid faster. You can see a video of the ice caddy after the break.
