What did you get rid of today?

The whole 5S concept.

They try to apply 5S where I work. In the prototype / warranty return / test lab.
A: "What is this thing?"
B: "That's a doohickey cabulator! We haven't used this in 5 years! Throw it out!"
some time later...
C: "Where is the doohickey cabulator? A warranty return came in from a customer. They have 10-year-old equipment."
A: "We through it out in the last 5S round."
B: "Let's get a new one! I'll get the purchase order going! How much are they, $10,000?"

Yeah. It's supposed to clear your mind. I don't know about that, but it does clear your wallet.

Hey, I love 5s (or 6s as they call it at my job, not sure where the extra s came from). It has provided me with tons of stuff for my home lab :)

Nice. Over here it's usually not an option though. A company can't give away stuff to employees like this, even if it doesn't have any use for this stuff anymore. It's considered as a "benefit", makes things complicated and it would end up as part of your income so you'd be taxed on it. But employers usually don't want to bother with all the paperwork and prefer throwing used gear away.

;D
And, 6S is the "Lean Six Sigma" BS. It's the new 5S indeed.

4.5 digit calibrator. Normally I am against this but it had cracked wafer switches and the things were press fit into the PCB before being soldered, just would not come out. I thought to buy chip-quick and give it a go with that and a torch, but it also had corrosion problems on the cables (that green shit that goes through the entire cable) and some broken transistor or something. Don't know the part # because it was painted over, digitek or something (defunct).
Felt a pang of guilt but I did get it on ebay for like $30 many years ago, but no schematics, and the compliance was funky too, wasted my entire day once when I was trying to test something and it turned out there was some weird hysterisis that if you hit the compliance limit, and then turned it back to 0, it would get a offset until you turned it off and on again. Generally unpleasant instrument to work with, I can do much better, and you needed to follow the output voltage with the compliance knob for it not to trip, there was cracked crimps on the transistor, and it also glitched out giving erronous voltages. bye troll. >:(
I highly recommend getting some jigs to hold parts in, or to bend the leads slightly, and do not make it press fit into VIA, because that is clown behavior. Bet there was cracked via's too in there because they built it with the 'broaching' process.
So I think I just freed up the rest of winter and spring by letting go of that 'log'.
Also when I ripped the switch out with the vias just to see when I gave up, it looks like they did not want to come out even with the soldering iron pressed against the lead of the switch when I was yanking on it with tweezers while everything is molten. A single stuck shaft on a bearding is enough to drive a man mad when its made of steel, but 30 wimpy copper parallel stamped rectangular shafts that are press fit and soldered to some plated shit on a fragile PCB?
bloody animals just packed it in to a cracker.
