Looks great!  What hfe range did you shoot for on the transistors?

Hi,

What bulb did you use on the mini-vibe?  I looked in your build docs and didn't see one specified.

Thanks!

Andy

Best option is to use low current bulb. I used 12v 20mA in my build.

Would you be able to point me to where you picked yours up from?  I'm not having much luck with the search and I'd hate to order the wrong one.

Thanks!

Thanks.  I thought about the switch wiring being the culprit, and it wouldn't be the first time I've made a mistake there.

I'll take a look at the switch when I get home and see if there's something funky going on.  I did recently change the wire I was using.  I went from teflon coated to the wire from small bear.  I'm hoping I didn't get it too hot and expose wire to ground.

Thanks,

Hi all,

I recently finished up a Sawse build and I'm having some weirdness happen.  I get bypass signal, but nothing when the effect is engaged.  I've gone through and done some preliminary debugging, but this one's got me stumped.

Here are some voltages:

IC1 (note: I subbed in an LM358 as I don't have a TL022 at the moment)
Pin 1: 4.627v
Pin 2: 4.634v
Pin 3: 4.628v
Pin 4: 0v
Pin 5: 4.616v
Pin 6: 4.630v
Pin 7: 4.623v
Pin 8: 9.28v

Vact 1:

LED +: 1.538v
LED - : 0
All three LDR pins read: 4.6v

The Range pot read (Fully CCW):

Pin 1: 1.423v
Pin 2: 1.423v
Pin 3: 9.28v

My power supply is a 1-Spot that is putting out 9.5v. 

Would anyone that's built this board please sanity check my numbers for me?  Also, would the substitution of the LM358 for the TL022 cause a problem?  I researched compatibility and found references where people have used the LM358 in place of the TL022 for LFO's and the like with no problem, so I thought I'd at least get noise.

As much as the Vactrol for this build cost I'd hate for it not to work. 

Thanks!

I got mine when they were posted to Facebook.  I'll be going fully dressed on this one with the enclosure and name plate.  I was also thinking about putting together a balanced line driver to have in case I wanted to run direct to the board.  Mainly because I have a couple of the THAT1646 chips in the stash and it would give me a reason to use them.

Great job on this beast! The PCB is freakin' huge!!

My bench is in my basement that has no windows.  It's like a Vegas casino when I go down there to work. I don't know how long I'm down there till I come back upstairs and realize I'm only getting a few hours of sleep because it's way past when I should have knocked off for the night.

I think a large part of my "problem" is that I build in volume.  I buy up a bunch of boards and start populating them till I run out of parts.  Most of the time I have enough parts on hand to get a large chunk of them to the point of needing pots.  That is where a lot of mine sit until I can afford to cough up a chunk of change for pots and jacks.  I'd say quite a few of these are still from my 2013 buy/build spree.  Eventually they'll get built up into enclosures.

Populating pcbs is my personal type of therapy.  I can do it for hours and it helps me to forget the stresses of the day.

I just went through and organized all of my unpopulated, partially populated and ready to be boxed pcbs, and I'm at 65 unique projects that need some form of love or another.

Anybody else have this issue?  Please don't tell me I'm alone in this.

Awesome!  I need to pick up the fuzz to round out my baby G collection.

Looks great!

Finished this one up last night.  I've built Zendrive clones before, but this little guy is something special. I used an NE5532 and I like it. I might try a couple others, but so far I like the way it sounds.

Now on to the interesting part of this build.  Everything is backwards. The pot wiring and the control labels are all backwards.  Oops.  That's what I get for thinking it was a good idea to finish this one after a few whiskys. The wiring will be an easy, albeit pain in the butt, to fix.  I'm going to have to strip the labeling off and I'm hoping the paint pen I used isn't too stubborn.  Let it be a lesson, don't drink and solder kids. You never know what might happen.

Thanks,

Coming from you guys that's the best compliment I could get. Y'all set the bar pretty high with regards to amazing builds.  Thanks!

Andy

Thanks!
