Sea Urchin problem..

I'm going to swap it out for a 4558. Let me get back to you in a sec. Thanks, Brian

[ckim715]

I'm stil only reading 6.8 with the 4558.

[ckim715]

voltage on the 1n4001 is reading 6.6. Could it be the 33R resistor, or the diode?

Are you sure you did not use a 3k3 resistor? Or higher? The bands should be orange-orange-black.

[ckim715]

the resistor bands are orange orange black gold brown. The DMM, set at 200 ohms, is reading 33.4.

[ckim715]

I think it might be a bad resistor. But would this explain the delay not working after a few minutes? If it was a bad resistor from the get go, and I'm not getting enough voltage, wouldn't it not work at all?

[ckim715]

Then again, if it was a bad resistor, my DmM wouldn't show 33.3, would it?

[madbean]

Take the resistor out and put a jumper in its place to see if that solves the problem. If you are running the effect on a well regulated power supply or battery it's superfluous, anyway. And it that does not solve it, then it could be somewhere else down the line in the supply chain.

[ckim715]

I jumpered the 33R, and now the LM7805 is getting massively hot. Can't figure out what's going on now.

[ckim715]

I have a 330R, is that too much to try and sub the 33R with?

[ckim715]

It was the 33R. I replaced it with a 100R, now it's working fine. Thanks again, Brian.

I've been away for a couple days...

glad to see you got it working
