I did buy a aoYue 852 however the air stream is to high and I blow the smd away.
I can not get it lower then 2.5 but it has to be get to 1 of 0.5.
I have look in it and try to find the fault, hoever it is equipped with a atmega 8 cpu and has triac regulators for the heat and the airpump, it uses pulswidth modulation.
This modulated output go into a npn buffer and then into a opto coupler who drives the triac, I do not see wel if this can be adjusted the right way, or need I to change the software or let the cpu working on a lower clock? she have use the internal atmega rc clock signal, lowering that do work then the air go lower also. I have try to make the resistor bigger on the opto coupler low voltage side, no effect, strange.
Someone tips or now what to do?. It does work quite good has no trouble to remove a chip.
