Part of the laboratory where have made a will
and worn-out the interface!
The interface has suffered a series of test with the purpose to optimize and to guarantee
a certain safety. It didn't suit me of to risk my Nokia 6150, I have so preferred, during
the phases of workmanship, to make a will and stressare the interface introduced on this
site.
To avoid of to engrave endless printouts I have realized the circuit on visible "
bread board " in orange. E' anchored to the roof of the container with the four
handle grips, some pins they communicate with the inside in way from to withdraw the
tension of feeding and the varied signals of clock automatically.
This solution is useful and he was born from the demand to reduce the times of preparation
during the phases of planning of my circuits. It contains, an adjustable power 1,2 - 24V
2A that use to feed the bread board, a generator of so that quadre and triangular whose
operational range can be select rotating a changer to 12 positions and other. For the
calibrazione of the frequency, that we desire to use for the varied tests, we have a
potenziometro for the standard regulation and one for that end. For the reading of the
frequency I have used the digital frequenzimetro that works from according to generating
of functions visible in the photos. 
I have provide ad powered the integrated one of the Maxim with different tensions
from those brought in the specific in way from to arrive to the destruction of the cip. If
desire the specific can now unload her! (memory that they are in the format .pdf, if you
don't succeed in visualizing you owe Acrobat Reader to install her 3.0 or superior
versions).
I have destroyed 3 cips MAX232 and 2 cips MAX3232 with the purpose to verify, further to
some technical parameters that I save up you, what it happened to the direct exits to the
jail cell and the zeners that protect it.
The solution adopted in this interface guarantees some correct borders of protection.
If you don't desire to connect you to Internet to send e-mail from yours portable, it
doesn't take an interest to manage your jail cell from the PC but you want to personalize
your Nokia simply, then, dates a glance to the interface to rays infrared IrDAs always introduced on this site. E' the ideal
solution for those people that desire something more " soft ", must be connected
naturally to the mother card of your PC.
