Fresh hacks every day
Lots of people build custom steampunk goggles, but most don’t implement any interactivity – they’re just an aesthetic accessory. [Sarah] recently decided to built a pair that, besides looking cool, would engage the wearer in creating sound. She accomplished this by integrating an optical theremin into their design.
To keep the build both affordable and wearable she researched simplified theremins, … Read the rest
We totally missed the ball on this project. It should have been run on April Fools’ day and you would have no idea if it were real or a hoax. That’s because the very serious performance given after the break is hard to watch without a least a bit of a chuckle. The instrument shown above is a Theremincello. It’s … Read the rest
This Digital IR Theremin creates tones based on the distance of an object from its IR sensor. There’s no microcontroller here, since the project is part of an Introduction to Digital Electronics course. Instead, it uses a handful of comparators, transistors, AND gates, and a 555 timer to make noise.
The comparators are connected to create window comparators. This … Read the rest
Multitouch builds are all the rage now, so it’s not surprising someone would come up with a multi-touchless interface sooner or later. [Hanspeter] did just that; his Multi-touchless ribbon controller, a.k.a. Polymagnetophonic Theremin is multi-touch without the touch.
[Hanspeter]‘s touchless ribbon controller uses an array of 24 Hall effect sensors that activate whenever a magnet mounted on a thimble … Read the rest
[Rob Morris] has been hard at working improving his guitar augmentation techniques. Here he’s demonstrating the use of an iPhone to control the effects while he plays. This builds on the work he shared a few years ago where he strapped a Wii remote to the body of his ax.
Just like the Wii remote, the iPhone includes … Read the rest
[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon.
The theremin is based on a simple LC oscillator built around a 7400 quad NAND gate IC, a wire antenna, and a few caps … Read the rest
[Chris] at PyroElectro sent in a great 8-part write-up of a miniature infrared theremin.
The theremin is based on a PIC microcontroller and an infrared distance sensor. The build log goes through the theory of operations for the IR sensor and tone generation. [Chris] definitely does a great job showing the math that went into the design.
Although … Read the rest
