    Circuit would be in a case and attached to a metal or hard surface . Upon impact or strong vibration with that surface, the circuit would trigger a bright led to project light to a flat surface approximately 12"-24" away. Light is small in size but visible from 30 yards as small dot. Light would reset via remote control. Battery should be of common use such as AA or 2016

    Two boards, the first reads two potentiometers and three simple press button switches and then passed this information serially to a second board. The second board has an audio input and two digital pots. It used the vales to raise or lower the incoming audio signal to provide a signal to a connectored amplifier. The volume is also passed onto a connected PC via a USB connection. Ideally all leade...
