On an somewhat unrelated note, I've had a lot of people having issues with printing transfers from the site. It seems Blogger resizes images sometimes when they're embedded in a blog post. So I've created a library with every PCB transfer already scaled and in PDF format. To access this library, just go to the top of the page and click on the "Transfer Image Library" tab. All you should have to do is download and print out of Adobe Reader. If for some reason a transfer image doesn't print correctly, I've also included the dimensions of the board in the PDF so resizing can be done if need be. Hopefully this will help alleviate any headaches resulting from trying to print transfer images. Happy etching.
Really nice, buddy! I love the idea of the PDF library, since I always vectorize the pictures from the site to print (actually, I vectorize them in Corel and make a file with a bunch to transfer again if the first try goes wrong). Way to go!
ReplyDeleteVerified!
ReplyDeleteBuilt and sounding nice! Thanks!
Thanks for the layout! I got this working, however it is a bit dark and the gain jumps way up at about 90%+ on the gain knob's travel. Found a forum post from years ago where voodoo labs suggests this may be due to incorrect parts values, and they offer to "fix" those versions. Any clue what these mods may be? http://www.voodoolab.com/forum/viewtopic.php?f=8&t=3164
ReplyDeleteLooks like there is a mistake in the layout... gain pot should be reverse log. That may account for the gain issue I had.
DeleteTry with a b100k pot ;-)
DeleteHi there David!
ReplyDeleteWould you have the schematic?
Is possible that the 47k res that comes from IC pin 2, should be 4k7?
This is probably the one I used. It's been a while...

Hi there!
DeleteI found that the lugs connection of Drive pot can change the sweep.
Going from 100nf cap to lug 2, can provide a nice sweep over the drive, due the A pot type.
9v 1A?
