Title: Fourth of July excitement (noob butchering equipment)
Post by: saturated on July 04, 2025, 11:39:37 PM
Anyhow so much for my plan getting voltage readings and stuff.  Because the boards face inward and the only way I can get access to the top of a board is by unplugging everything

Besides why do that when you can do bonehead stuff like remove components for no reason except that somewhere sometime some guy amongst the entire world 🌎 had that part go bad

Oh well I need some practice anyway.

So I removed Q24

To be fair i did diode and resistance checks but yeah I guess in circuit they could mean anything.

So while all the cool people in town are partying and getting lit and spending hundreds of dollars on fireworks 🎆 🎇 guess what my excitement is:

Testing this PNP device on my peak atlas.

Oh wait I have a multimeter I'll do that first

Well little did I know the fun actually was NOT 🚫🚭 over

I had pulled C23 as well and checked it ✅✔️

No smoking gun so I put everything back together

Or so I thought
:grr

I plugged it back in turned it on and to my horror the relays were clicking so bad it sounded like a bowl of rice crispies (or Orville Reddenbocker)

So I thought I had plugged something in wrong or left something unplugged but it looked ok
Then I started wondering if I soldered the transistors in backwards.

Well here is a pic with C24 removed

I had written down on my notes C24 at the top so when I glanced to look for the markings I thought top to bottom = left to right.

Oh well

Time to do it again....more practice  :trouble

At least you didn't make any fireworks out of that PCB.
I read somewhere that people think fireworks should be  banned because they could be dangerous, I guess that just leaves us firing guns in the air instead.
Now where can I get an AK47 from cheap......
