this is a private page on a few technical projects:
electrical and mechanical projects are dangerous and I am not responsible for your eventual reproduction

be careful! it's on your health!

  DANGER 230V~  

most projects require 230V~ and because of that they are dangerous
serious damage on health and even death may occur

 >> HIGH VOLTAGE <<

the entry on shorttime photography works with voltages above! a few 1000V
serious damage on health and death may occur
the combination that this high voltage is DC and the high load of the capacitors make it even worse
remember! the capacitors are even loaded after disconecting the board!!!

 ! CHEMICALS !

see security documents for your acid !! e.g. Sodium persulfate Na2S2O8 or Iron(III)chloride Fe3Cl
sicherheitsdatenblätter für Säuren beachten !!  z.B. natriumpersulfat  Na2S2O8 or Eisen(III)-chlorid  Fe3Cl
they are dangerous! for your health and raise burning, various allergies may arise and stay by contact with Na2S2O8
even more dangerous is your Sodium hydroxide, NaOH(natriumhydroxid) used for developing the PCB
a little splash can make you blind, it's corrosive -see security documents!
always wear handgloves and protection-goggles  - these informations are not complete! be careful! it's on your health!
