Building the Op-amp Tester for single, dual & quad packages. Dual-polarity LED indicator.

Описание: Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on https://www.pcbway.com/ In a previous design video, I outlined the design criteria for this tester. I have now received the PCB's and am building the project. I will then be testing it to ensure that we have a viable project.
As mentioned in the design video, the basic concept involves creating a vibrator circuit using the op-amp under test as the driver, to drive an indicator LED. A dual-polarity LED is used in this case, as it provides a simple two-colour indication of a functioning op-amp.
