Inductometro & Capacimetro

Para quienes deseen armar un inductometro a bajo costo, yo arme y
el costo total no pasa de USD 2,oo, lo mas caro es IC 74HC132 que
si lo piden a digi-key cuesta USD 0,37, en mi pais Ecuador lo
compre por USD 1,50.
No olviden de cambiar le valor de la resistencia R3 de 200 ohm a
300 ohm, una de 200 ohm + una de 100 ohm en serie. Por lo demas
trabaja perfecto, solo se debe calibrar con una bobina de valor
conocido tal y como explica la literatura que acompaña al esquema.
La alimentacion puede ser una bateria de 9v. o una fuente regulada
a 8VDC.
Si tienen dudas pueden escribir al que publico este proyecto en internet.
Adjunto las comunicaciones que hemos intercambiado y tambien la
consulta sobre el costo del IC que hice a digi-key.

Hello my dear friend,

Yes, Digi-Key, here in the USA, does have that chip.
Just go to...

http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=106752&Row=176493&Site=US

...and you will find the chip that you need for the
Capacitance Project.

E-mail Digi-Key and request that chip. Ask them to
send it the most economincal way, through regular
mail. It may take days to come in, but it will not
cost that much for shipping and handling...if you
remember to request the most cheapest way to send it
to you. Possible order a few of them, since the chip
itself is very inexpensive...as you will see by the
LINK I gave you. That way, your next project can be
the Inductance Meter, and you will have your chip at
hand!

Do let me know how things go, my friend!

...and let the project begin ! ! !

...your friend, Patrick
