A litany of dumbassery

If I ever design any modules, I might actually release them under this name :sweat_smile:

So much for finishing my AO reverb without another order. sigh

After a while struggling to finish anything, i went and bought 2 ALPS-SRBV switches i needed for 2 modules. Nice choice because there were full metal, i thought.

I soldered them in and…didn’t check how many uhm…positions they have? Apparently a part of me thought they might be all the same.

So i just didn’t check, i just checked if they clicked okay, but not how many switching positions there actually are and no…of course it doesn’t fit the needs. I have to de-solder those 10 pins, two times.

On the positive side:
Turns out i had 2 fitting switches, purchased a long time ago, in a box, right where it says “Switches”.

I’´m not gonna hate myself now, because for a change i have motivation again after months and months, but maaan, what a waste of energy, nerves and time.

Check your parts before soldering! :smiley: :wink:

now you have other switches for something else!

This is when I’m glad I have a hot air station.

I have one too. But i have to order some flux and it’s -1°C (31°F) outside, so the temperature in my basement is not fit for a good de-soldering session.

But like i said, what happened…happened. I use the module as it is until it can be fixed.

This was a close one…who…just who puts square pads on the + side?

But it went fine i guess…haven’t tested it yet because →

I dont understand why, and cant really be blamed other than for not checking but this had me puzzeled for a few mins on the build of this pcb.

  • I had the supply capacitors oriented wrong in the layout, even though I double checked.
  • Obviously followed the layout blindly and placed them reversed in the stripboard.
  • I ignored the faint pop and even more faint smell when tested the board, since everything looked okay (?) and power was measured correct where it was supposed to go.
  • Fortunately, I took some oscilloscope measurements before I plugged thd module in and realised that there’s something very wrong with it.

Turns out that the explosions of small electrolytic capacitors can be very unimpressive, or even hard to notice at first sight.

This module use to work, why is it not working now? Oh …
