I finally did it... spent 2 1/2 hours soldering on perf board for a circuit based around a  74LS174 chip (non-stompbox circuit).  Everything was going great... got all the pins connected working in a tight space... feeling good... then I went to put the chip in and oops  :icon_redface: .  It hit me... the chip socket was backwards!  Pins 1..8 were where pins 16..9 shoulda been.  So as in the Master Card ads:

Perfboard : $1.75
Components : $1.00
Chip socket : $1.00
Wasting 2 1/2 hours to become the new village idiot... Priceless

There are some things money can buy... the rest require sheer stupidity.

Just bend the pins the opposite way and put the chip in right-side up-side down. (assuming that inversion will right your layout)

You're far from the only one to have done this.  :icon_wink:

I actually thought about doing that, but didn't know if I would break the pins.  Not that the $0.50 for the chip really matters, but the further defeat and shame it would bring would have been too much at the moment  :icon_rolleyes:

I know I am probably not the first to make that mistake, but the feeling of "DOH!!!" will live on for a while.  I had been meaning to build this circuit for awhile, but kept putting it off as the build was just meant to be a quick trivial thing in pursuit of other greatness... now I know that nothing is truly trivial.

Besides, I could (obviously) use the practice.  :icon_eek:

  It is possible, try not to make the entire bend at one point of the lead.

Yes, there's plenty of "Old village idiot's" still here, who should know better  !!!

Yeah, this village doesn't have a village idiot. We take it in turns.

It was my turn yesterday, when I started to make a proto, by soldering a socket to a stripboard & then drilling out the traces between opposing pins. Then when I went to put the first component in, I noticed all the strips were running at right angles to where they should be :icon_redface:

yip, live and learn . . .   at least those components are cheap. and your time is an investment in learning.  Sometimes it takes five revisions to get somethign right then you still don't like it, and it's back to the drawing board like wile-e-coyote.

Wait until you f'ck up the drill pattern on a $14 hammond box or smoke a matched pair of vintage tung-sol's.
