I made this circuit that is just an astable 555 powered by a capacitive dropper with the output connected to the gate of a MAC97A6 triac. The load (a dimmable LED lamp) does flash, but it never fully turns off, how can I solve this? The triac gate voltage and current seem to be fine.
It is relevant, when you connect a speaker you can hear 60hz mains frequency superimposed with the high frequency tone the circuit makes. For some reason this is not the case with the 12v transformer.
Its a hobby thing
I was first running it with a 12v wii power brick, now im running it with a 12v transformer and a half wave rectifier. I changed because the SMPS introduces noise to the circuit
I made a 2n2222 oscilator (the super simple type)
it works with a speaker, but i tried to power a ferrite transformer with it and it seems it stops the oscillation. The transformer has 20t on primary and 310t on secondary, i wanted to use it as a fluorescent lamp instant starter.
I dont get...
the transformer has a ferrite core
30 turns on primary 250 on secondary (new version has 20 turns on pri and 400 on sec
The primary is 1 mm wire and the sec is 0.1 mm
I made a small transformer with 30 turns on primary and around 250 turns on the secondary and I want to know how to drive it. I thought I could drive it with a 2N2222 oscillator like this one
Could I just replace the LED with the primary of my transformer? What effect would this have on the...
