mga boss pahingi naman dyan ng diagram ng buzzer...gusto ko kasi mag-assemble nalang para di na ako bibili ng tester .. ........gagamitin ko kasi pang tester ng cotinuity.. masmadali kasi sa circuit tracing pag buzzer ang gagamitin.

mura na lang sir ang tester na may buzzer sa raon...

kung gagawa kayo for continuity, kuha kayo ng battery at yung buzzer. connect the + of the battery to a probe and another end of a buzzer to another probe. tapos connected na yung - ng battery at another end of buzzer.

Uy, maganda yan ckt. Low injected voltage pa.

Pwede din blinking LEd unless bulag and user.

Bumili na ka na lang ng alito FM na may earphone na P60 lang ata. Break the battery connection and put a probe. Ayan, pag kumanta, on yun.

mecaniko, hi! I am wondering what had happened to your buzzer continuity tester. Alam mo, the worst kind of continuity tester is the one in hardwares, even Ace, where they use 220 v in series with a bulb. Isa, delikado sa tao,k ikalawa mataas ang injected voltage na ok lang kung blb lang ang under test.

Alam mo a simple buzzer in series with a battery is fine in as long as hindi mo gamitin sa devices na sensitive to high V or high current. The cellphone battery na Li Ion as 4.2 volts and you have to find a buzzer na tutunog at that voltage. MArami pa nga ako ganoon. yung circuit ni Kasamiko may advantage na ang |V and current doon sa probe maliit lang. may safe sa equipment under test.

Bumili ka na lang ng either blinking LED o yung dual color. Series mo ng resistor, the battery, then the probes. Pag may contact, sisindi. m,ayroon gangyan sa Radio Shack at mayroon ako nun. Led lang. Nice for quick test ng bumbilla, ballast, relay, etc..

let me kow if you need help.
