How-To: LED VU-Meter Necktie
Check out Becky’s latest wearables project over at adafruit. With special guest appearance by Collin Cunningham.
Collin’s Lab: DIY Contact Mic
It’s amazing what a little disk can do … when it’s layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp – a basic circuit used to match the piezo’s signal to levels compatible with modern audio gear inputs. The resulting piezo/preamp combo can be used for electrifying an acoustic guitar or simply exploring the lesser-heard world of small sound around us.
Collin’s Lab: Schematics
Schematics are the functional diagram of electronic circuits. Understanding how to read schematics can unlock a world of possibilities for the electronics maker.
Circuit Skills: Infrared Light, sponsored by Jameco Electronics
Infrared light may be invisible to the human eye, but its usefulness in the world of electronics is easy to see. From simple object sensors to wireless data transmission, IR emitters & detectors can be used in a variety of different ways – and their low cost and wide availability makes them a great choice for enhancing an electronics project.
