Building capacitive sensitive floor tiles

That title’s a mouthful but you’re already familiar with the technology and application of foot pads as sensors in games like Dance Dance Revolution. The usbddr project sought to make a USB connected DDR controller from scratch. The microcontroller used is an Atmel ATmega8 running the V-USB firmware for connectivity and uses the analog to digital converts to read in data from the capacitive sensors.

The physical implementation is cleaver. The base plate has a capacitor plate attached to the top of it and the tile has the other capacitor plate attached to the bottom of it. The two are separated by some weather-stripping which is spongy enough to allow compression, bringing the two capacitor plates together.

We’re not convinced of the long-term durability of the system. We certainly don’t think it will hold up to very much hard-core DDR playing. But we would love to see a Super Mario RPG style puzzle to unlock the door to the ‘castle’ at a child’s birthday party.

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.

Ever been curious how a pole transformer is made? Quench that curiosity with this educational video. [via HackedGadets]

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.
