Hacks and Mods: Tweeter Used to Sense Vibrations

Schematic Diagrams      Comments Off on Hacks and Mods: Tweeter Used to Sense Vibrations

The creator built a neat looking project which uses a piezoelectric element from a tweeter to detect vibrations. He is using a Zilog eZ8 series microcontroller which seemed to be very popular years ago. This project dependently using a strong vibration while the enclosure has been placed on the top… Read more »

Non-Contact Power Monitor

Schematic Diagrams      Comments Off on Non-Contact Power Monitor

Here is a simple non-contact AC power monitor for home appliances and laboratory equipment that should remain continuously switched-on. A fuse failure or power breakdown in the equipment going unnoticed may cause irreparable loss. The monitor sounds an alarm on detecting power failure to the equipment. The circuit is built… Read more »
