I've got some additional stuff for a good home.
I've got three (3) Burr-Brown (TI) INA125P load cell interface chip. The chip contains an instrumentation amplifier and a precision voltage source to drive a load cell bridge. It can run on a single supply voltage, from 2.7 to 36 volts (single supply means it only needs a positive voltage and a ground). Chip should run great from a battery! 16 pin DIP style.

I've got two (2) Analog Devices AMP02FS High Accuracy Instrumentation Amplifiers. Gain is set with an external resistor. These are similar to the above chips, except they require a precision voltage source for use with a load cell. requires split power supply (+ and - voltage and ground). 8 lead PDIP style.

I have two (2) Analog Devices AD620AN Instrumentation Amplifiers (8 pin DIP)

And two (2) Analog Devices AD622AN Instrumentation Amplifiers (8 pin DIP)

Again, all I'm asking is for you to cover the cost of shipping. I think any of these should fit into an envelope. I don't think postage should be more than $10. ($10 is the cost of a Priority Mail Small Flat Rate Box).
