Tnx for the ideas. It was just a typo. error. I mean "Use ADC0832 instead of using ADC0831". Since ADC0831 has a separate pin (Vref) and ADC0832 integrates both the Vcc and Vref, the real problem is that how to change the usual resolution from 0-5V, to 1.5-4.16 for an instance. Tnx for the suggestion!

I tried to use ADC0832 instead of ADC0832. The problem is that, internally Vref is tied in Vcc pin of the ADC0832; I just want to use this IC so that the volatge input range should be in 1.6-4.2V or any range below 5V, instead of the usual 0-5V. I can't figure out how to do this? Any Ideas!

Sorry for the bad link.... I've already completing the documentation of this project. My proposed modifications are: 1. Convert the original dos-based program into window-based using Visual Basic and added some features. 2. Replace the concept of battery-operated instead use 5V regulated power supply from AC source. 3. Use the finger probes in this link: (Promise this link works!) http://www.plazaearth.com/usr/gasperi/gsr.htm Please give any comments, or suggesstions how I do all that stuffs! Tnx for the reply....

Hi, I'm a undergrad Computer Engineering. May I have an assistance regarding my proposed project. I've already found the needed circuit in this pdf file: http://www.schematicsforfree.com/misc_circuits/Biofeedback_Monitor-PC_based.pdf Any information, comments will be a great help!!!!! Tnx....

I'm a computer engineering and I'm thinking a design project that will utilize a computer monitor as a medium to connect a pheriperal devices like VCD, DVD without using CPU? Please let me know if it is possible! Waiting for any infos immediately.
