PT2399 test circuit

[Dirk_Hendrik]

To be able to do some testing prior to design I made a small PT2399 board which just contains the Princeton application note for the chip. Since the cost is close to nothing it might be handy in experimenting with the chip.

Check the Rebote delays for comparison. They use the same chip.

I'm fully aware of that. However, I needed a test app for the chip as basic as possible with the focus on small, cheap, quick build, etc. Main focus was using multiple chips (since thay come so cheap) and I don't want to build multiple rebote's for e T&M setup.
Right now I got 2 of  them cascaded to verify I could use 1 delay pot which have both pins for the delaytime connected to. Can be done... with some drawbacks.. minimal resistance his 1.6 Kohms. Otherwise you'll get funny noises on the background.
