Need some advice on fixing power issues with my instructable Answered
So I built an Atari punk synth using instructions on this site and made it a bit more advanced. It has six 555 timers and button controls. Now I would like to power this thing with a 9volt wall plug, the same thing I use for my effect pedals, but I have crazy power issues when I set it up this way.
It works fine when I just use a 9 volt battery, but when it's set up to be used with a 9 volt wall plug it seems like its getting way to much power. The sound goes crazy and it blows out my LEDs even though I have resistors on them. I've tried putting a resistor on the power jack, but it doesn't sound right when I do that and it still doesn't work right.
So I'm curious what's exactly going on here. Regular effect pedals that run on 9 volts work fine with the wall plug and even the instructables on here say you can use them. But for some reason this thing only will work with a battery. Could it be the parts I'm using? I have a feeling it has to do with wattage and my parts just can't handle it.
Any advice would be greatly appreciated.
