Title: Mildly OT: Third Times the charm?
Post by: Somicide on April 21, 2004, 11:31:51 AM
How many times have you guys done a breadboard (or in my case
cardboard...) of a particular circuit, to have it work once, and then
when you move the sucker to a decent board, it craps out on you?  

My FuzzFace NPN, Neg Grnd did that;  put the sucker on cardboard,
soldered leads to each other (lots of spare parts...) and it fired right up.  
Moved it to a PCB (home etch, oh yea...) and the fscker didnt want
anything to do with me.

:) I stopped counting... dont even remeber when. Just keep trying, thats the idea, yeah.

You should think positively, and there are some helpful tricks you can do (worked for me few times anyway)

Say, you can solve adifficult problem easier by setting a question "How would Lonely Rider solve this problem?"

Aside and go to debugging it.
 The problem has to be in there.
 Once you find it using signal injector, [ I use my thumb to connect to points in the cct to find loss working from output] or audio probe or DMM, then you have to discover why. That's the tricky part. say you have something funny going on [post your Qpin voltages from ground], you have to find why...could be just about anything.
 Post the pin Voltages, trace through it with audio probe [see debugging page] then you'll probably have enough to  better isolate problem finding.

i prefer 2 *see* my electrons distort.
so......i use a scope 4 troubleshooting.
makes (electronic)life much easier....
staytuned

I don't see anything wrong with doing circuits on cardboard, or the dead bug, or hanging garden methods, and just leaving them @ that. Whatever it takes you know. The 2nd effect I ever bought(after my Shin-ei Fuzz-Wah) was a EH LPB-2, & when I opened that up the first time to change the battery I was shocked to find a little tiny hanging garden circuit wired to the pot!! If it was good enough for them, it's good enough for me. The Commonsound collective shows how to glue a picture of their layouts on a piece of cardboard and build like that, very cool IMNSHO!!

Title: I like my cardboard too...

Haha, yes, those methods are good, But I didn't think my cardboard was sturdy enough.  Well, Hopefully, we'll see a good fuzz at some point soon.
You guys're great.

I did some using counter top stuff and book binder.
 pull them parts up sorta tight so they arent moving all over and I don't see why after mounting it shouldn't be sturdy. Looping wires through the board to stabilize the conntections...mount the board...should last just fine.
 Who was it had the dowel rod method...wrapping small cct's right around a dowel rod IIRC...

yea wrapped around and drilled through for offbaord wiring.
