trip to Radioshack......
I went to Radio Shack, and bought 90% of the stuff on the schematics. I bought a simple Op-Amp ($.99), but on the back of the box schematics, it only has 2 inputs, and an output. Your schematics have a ground coming out, as well as another wire (#4 on sheet) that appears to be +12v. I guess I'll have to take another trip out to R.S. and pick one up that looks similar.
Also, it dawned on me just now that i will have to put many resisters in series to create a net resistance of 12.1kOhm's and 2.2kOhms. I did not see these resisters at R.S, so i didnt buy them, only the nice round 10X mulitples R.S. had. Looks like 1 more trip out to Radio Shack today........ but probably not the last..... ![]() |
