Paano yung pagkuha ng oscillation neto?

Teka dito yan galing eh.

gusto ko lang malaman yung talagang working frequency.

Ito drinowing ko na lang.

Sa google mobile ko ganun din lumalabas lang tri pod.

Left resistor value ay 470 then 22 ohms respectively.

sa tingin ko gagamit ka ng freq counter kasi nagvavary ang freq depende sa voltage at load na tube yan eh

Any mathematical equation para makuha yung approximate?

ang problema kasi ung inductor kung ilang H.

You need a freq counter. google up on the LM555 and look for the cirdcuit on how to make an oscillator. may table of R and C to get a particular frequency, then use it to drive the transistor in your circuit. When you get a similar brightness on the FL, pareho silang F. Get it?

Hmm balik aral at testing uli pala.

Ok lang yung sa 555 kasi merong table of RC combination para makuha yung approximate frequency. And the simple signal injector meron akong nakuhang mathematical formula to get the desired(approximate) operating frequency.

Dito lang kasi ako walang mahanap for reference. Balik testing uli. tnx again mga sis. Isang saging muna sa inyo.
