Firstly, although it happened a while ago, I was shocked to learn just now that Kris Heidenstrom passed away earlier this year. I never met him in person even though we both live in New Zealand, but he was a good guy, always willing to help me with my project and the circuit he designed for me was exactly what I needed. So sad he has left us.
Sadly though, I need help with the circuit he designed for me. I had emailed him previously having no idea of his passing, not til I came here hoping to find Kris did I learn what happened.
The circuit he designed for me is a lighting sequence control circuit for a model I have built. I found Kris on this forum and sought his help explaining that I wanted sections of my model to light up in time to music played thru the model. Kris gave me the schematics for a tone detector that would, as the name suggests, detect tones hidden in one channel of the music I would play. The detector would then send signals thru to a sequence generator that would in turn light different segments of my model. Everything worked perfectly. Kris helped me with getting an MP3 player to send the tones to the detector and helped trouble shoot my circuits when I couldn't get them to work. He even helped me with some touch sensitive switches I wanted use, which I might add, thanks to Kris, work perfectly.
Now heres my problem. Back when we were building up the circuit Kris suggested I would need an amplifier to get the sound coming thru nice and clear. At the time I was overwhelmed with the rest of the circuit and so sorted pushed it to the side. I'm kicking myself for that because a couple of months ago I went and got a small amplifier circuit from a hobby electronics store and hooked it into my main circuit. Something in the amp is effecting the tone detector as it is no longer picking up the signals from the MP3 player.
I'm a total novice at electronics. Kris helped me with learning continuity and such but when it comes to full on troubleshooting I have no idea where to start. I have tried isolating the amp circuit with diodes but don't even know if thats the right thing to do.
Please, is anyone able to help me with this? I will do my best to provide as much information as needed. I still have Kris' circuit diagrams and I have a spec sheet for the amp circuit, though its mostly alien to me.
This is the FINAL piece of my model project, something that has take me, on and off, almost 10 years to build. I'm keen to have it finished and, although I don't NEED the amplifier to run the sequence, Kris was right in that it has given me much much clearer, louder sound.
I'm almost begging for help from anyone willing.
Thanks to all
