[Matt] noticed an overabundance of sous vide builds in the past week, so he decided to throw his Home made meat smoker into the ring. There’s not many things more delicious than a nice cut of smoked meat, and the fact that it’s very similar to the sous vide hacks we’ve seen is an added bonus.
[Matt] decided to build a ceramic smoker like a Big Green Egg. He took a cue from [Alton Brown] and used two terracotta planters and a hot plate for the smoker. For controlling the hot plate, the cheap $35 PID controller we’ve seen in a few sous vide builds was used. The PID can’t control the 7 amps of AC that the hot plate needs, so [Matt] used a solid-state relay he had lying around.
A stainless steel mixing bowl was placed on the hot plate for wood chips. So far, [Matt] has run his smoker for more than 12 consecutive hours, and the results are really promising – there wasn’t much change in temperature between the chill of the morning and the heat of afternoon. [Matt]’s build is great and perfect for venison jerky now that deer season is coming up.
We’ve seen videos of people attaching chairs to gigantic welding robots and riding them around the shop, and while that would be fun for a little bit, the joy would be fleeting. Flight simulators built on a Stewart Platform are becoming old hat. Now there’s a new robot we want to ride.
[Saul Griffith] from Otherlab has been working on pneumatic robots for some time now, and he just wrapped up his Ant-Roach build seen above. It’s a 15-foot-long cross between an anteater and a cockroach that’s completely inflatable and can actually walk with the help of an air compressor.
The ‘muscles’ of the ant-roach are fabric actuators that contract when inflated. Of course this makes the mechanics look like something out a biology book, but the robot is still a neat piece of engineering. The ant-roach weighs in at 70 pounds but could probably support a half-ton of riders.
From the videos after the break, we can see that the ant-roach looks a little clumsy when walking. [Travis Deyle] sent in his contribution that details an amazing inflatable robotic arm that can beat any human in an arm wrestling match. Now we can’t wait for a giant anthropomorphized bouncy castle to start lumbering to a children’s carnival.
