Which "some"?
Please take a better picture of the component side.

What the fuck do you expect? We can't measure then Zener values, but you 
can do it...

Remove the epoxy coating using a appropriate solvent, solder out the 
Zeners and measure.

May be, you're a little bit more lazy than you should...

I am here asking experienced people to help me if they can, I tried to 
remove the items but it was broken and according to my research there is 
no way to remove the glue.
And about being lazy, I am not an electronics engineer, and I already 
get the values of some components but I am not 100% sure of the values 
and I will upload the Image, In the end sorry for angering you.

hi,
Could you tell me if you managed to make this regulator? I also need 
such a device but I can't find any source.

I used a universal AVR available on aliexp ... But the problem is that 
this generator does not want to wake up itself. It can be done as an 
additional coil used behind the cutter. Power connection from this coil 
is on. Bridge rectifier for test procedure. Perform the function also 
connected to the control function. During the under load tests, we 
claimed that it was tested on a trial basis, and after firing it it woke 
up with no problem.
Alternatively, excitation can be created by meticulous magnesia on 
through as done in Chinese.
