Milk Tester Updates-:

This month we have taken readings with the new program that we were given by Neil,but unfortunately I used the old circuit.I was not able to load the program in the new circuit.This month there will be more work on the circuitry and the progarm so that I can use the new circuit as well as the program to take the readings.
Low cost hearing Aid-:

The low cost was hearing aid was ready for use this month.The Circuit diagram were picked from August 2003 issue of EFY.The circuit was modified further and now can give greater clarity of voice up to 4 meters.We are testing the circuit and we will finally promote it as low cost product for village people.

The cost of the circuit is less than Rs.80 and can be very handy.The dimensions are about 7 C.M. ,4 C.M. , 4 C.M. Its weight is also very low with batteries contributing most of it. We are working further to simplify the circuit more so that assembling the circuit becomes a layman's job.
