DIY Indoor Outdoor concrete lamp 2
Thank you very much for posting, and taking the time to document a great project. I am building at the moment and am having an issue similar to that mentioned below. I have changed all transistors to 3904 and when I switch it on all the LEDs blink without any audio.I have been troubleshooting and I believe the High pass filter is oscillating, if I ground the input to R17, the blue LEDs go out and the Green and Red respond as expected :) If I reconnect R17 on the high pass filter and add a 0.22uF cap from the junction of R17/C9 to GND, all seems to be well. But I suspect that alters the pass frequency of the filter. Can you suggest a better fix?Thanks.
