this is a private page on a few technical
electrical and mechanical projects are dangerous and I am not
responsible for your eventual reproduction
or experiments and their possible
be careful! it's on your health!
most projects require 230V~ and because of
that they are dangerous
serious damage on health and even death may
>> HIGH VOLTAGE <<
the entry on shorttime photography works with
voltages above! a few 1000V
serious damage on health and death may
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
Säuren beachten !! z.B. natriumpersulfat Na2S2O8 or Eisen(III)-chlorid
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
little splash can make you blind, it's corrosive -see security
handgloves and protection-goggles - these informations are not complete! be
careful! it's on your health!
