You seemed to had run into the same problem I did, with the LED’s mounted on the front of the board you cannot find a good location to mount it. I went ahead and inverted all my LED’s to the rear of the board so I could mount it in my box.I also had to use a larger box than you,6″ 3″. You can check it out at our myspace, http://www.myspace.com/bprs08 . Any questions just contact me.

Thanks for the photos! I’m pretty sure I have the circuit wired together correctly now. It works, but I think the geophone element I got just isn’t as sensitive as I’d like it to be.

Sorry guys has a Moon River and Gettysburg weekend back to back. Here are photos:

Tried to zoom up as close as I could without losing to much sharpness.

Hi, Any luck with those photos? I have all the parts put together now, but it doesn’t seem to be as sensitive as it should be… I’m hoping I’m just missing something simple!

Thanks!

Hey i found the IC’s at this place, http://avnetexpress.avnet.com/store/em/EMController/_/A-1411817/An-0?action=part&catalogId=500201&storeId=500201&langId=-1 but still looking for the geophone pickups, anyone able to find’em?

Thanks a lot! I’m looking forward to seeing them and figuring out how to put this little gadget together.

I am getting the pictures and will email them to you, yes they came with a schematic but unfortunately they went into the trash a while ago.

Hello again… I just remembered… did the bg micro geophone kit come with a schematic drawn in the manual? If so, that may be all I’m looking for! A photo of that would be awesome. Thanks!

Hey there… Thanks for listing the geophone element info and lm3915. I’ve been looking all over for the components also! Is there any chance you could either take a closeup photo of the front and then the back of the circuit board, or list out the other little components…. I’m trying to figure out exactly which pieces to get for the circuit board including the resistors, trim pot, any capacitors, the little blue boxes. The color bands on the resistor (if there is one) would be good to know. This would be a HUGE help. Thanks a ton!

I don’t know much about electronics also, but I think this would be a pretty fun project to start with!
