Hackaday Links: Sunday November 22

Hacklab’s laser cutter got the customary musical treatment. You can see it play the theme from mario brothers here. It’s nothing new to us, but we still enjoy seeing it done.

Here’s a quasi humanoid robot that is designed to be your workout trainer. He’ll show you the¬†exercises, give you motivational and encouraging pep talks and even play games with you. We think the idea sounds good, but in execution, he flails his arms and randomly says creepy insincere sounding things like “I’m having ¬†fun. I could play this game all day long. I’m having too much fun.” That’s just creepy.

[Mr. Nelson] got sick of walking all the way down the hall just to see if there was anyone in the bathroom. His solution was to build this massively overdone indicator light system. It uses a proximity sensor located in each bathroom to determine occupied status and has a fantastic industrial look.

If you’ve ever wanted to get into 3d photography you’ll be pleased to see this writeup on how to build a simple rig and compile the images for different viewing methods.

We were amazed by these beautifully crafted brass machines. The one in this video is solar powered and seems to run pretty smoothly. Not bad for something that was all hand crafted from sheets of brass.

Be careful with this one folks. This video shows how to melt a beer bottle in your microwave. We’re not sure why you would want to, but we sure enjoyed watching it happen. Maybe that’s reason enough.

Theremin controlled Mario

In the video above, [conquerearth] is using a theremin to control Super Mario Bros. Moving his hand toward and away from the vertical antenna increases the theremin’s pitch. The computer monitors this in real time and moves Mario left and right. The loop antenna controls the theremin’s volume and acts as the jump button. The controls seem to work well, much better than the sound of one man flailing at a theremin.
