PCM codecs

We had a dream. We wanted our devices to transmit voice data over hardware PCM codecs. Here's the long process of turning dreams into reality.

		A small thing, isn't it ? The scale is in centimeters of course.

		Just to make sure - here is the codec compared to a match.

		First of all - we designed, painted and etched the PCB (Printed Circuit Board).

		After drilling it was time to solder our little gem - manually ! A small drop of glue made the IC sit still on the board.

		That's the whole board.

		Before soldering the other components - look how big a 3.5'' diskette is (compared to the codec) !

		First components...

		... more components ...

		Voila ! The PCM codec board is ready ! Hopefully it won't burn after turning the power on...

		Statistics: six PCM codecs bought four burnt (you can see them in our "death-house" - we shouldn't have used capacitors to debug the circuilt ;-) two more left and still working
