stroboscopic vibration meter, a small handheld device, controlled by the well known IC NE555, with several operation ranges from abt 10 Hz to 4 kHz, a compact solution with the power output for a super bright LED spot light - see the bottom right hand corner of the open box below. Perhaps a useful and simple screening tool for initial stages of vocal cords carcinoma as well. There are other innovative features in this technical solution e g the application of power MOS BUZ 11 in the output for super-bright LEDs, separate sound output, voltage stabilization for the 555 circuit etc. Supplied by rechargeagle or normal 9V batteries. Very good stability and cheap constuction. |
