Your design is bad and you should feel bad for it.

A friend of mine posted a link to this on Facebook and it is literally one of the worst designs for anything I have ever seen.
Straight from the Walmart online marketplace, right next to the counterfeit Duracell batteries

Not that any of these have ever been designed WELL, but this is worse…

It’s literally the worst designed ear piercing gun I’ve ever heard of. Of particular note though, the description suggests it can also be used on the nose or navel. How? No, don’t. Just don’t. On anything.

Also note the random weirdass stud jewelry that comes stuck in a sheet of pink antistatic foam.

A little background on how these things are supposed to work: The tip of the stud (not seen anywhere in the description photos) is pointed. Not really all that sharp, but pointed. The butterfly back of the stud earring is placed in the other end of the gun and it’s driven by brute force (this one appears to use a spring) through the earlobe.

The most common place you find these things is in kiosks and stores in the mall. Claire’s uses a variation made by Studex and theirs has a disposable sterilized plastic cartridge that goes at the end. The gun itself can never be fully cleaned or sterilized, but at least most of it is not in contact with the person it’s used on. Thanks to this, infection caused by bloodborne pathogens left on the gun itself is at least rare. The complications caused by the body trying to heal a rough bruised hole created by jamming a somewhat dull metal stud through, that’s another story. This one, uhhhhh….

good luck

On this design you just get a little stack of steel plates with a notch in them. The outer one is bent to hold the butterfly back of the earring. Sort of. I can’t really imagine how it keeps it lined up such that the stud will align with the hole in the end – chances are better it just kind of crashes into it and either further tears the hole by skewing at an angle, or launches the backing into space.

But it’s not covered with any sort of disposable part…. and it couldn’t even be effectively wiped down to clean it because it’s got all those gaps between the plates.

A felt tipped pen and a magnifying glass are also included for your convenience. I can’t even understand why, as there’s no logical reason this thing should actually make the hole where you want it to land.

 

It should be no secret that I think the ear piercing gun is one of the worst products of modern misengineering, but this just… this deserves some kind of award. This is BAD and whoever designed it should feel bad for it.

Yeah. Do yourself a favor and go find a member of the Association of Professional Piercers if you’re looking to get any sort of piercings and want the process to go as well as possible.

And do beware of the utter bullshit that shows up in the Walmart “marketplace”. Same goes for Sears. It’s all the ecommerce equivalent of the Opa-Locka Hialeah Flea Market or something.

The Analyzer’s New Clothes

This Tektronix 1705A L-band spectrum analyzer has temporarily borrowed a garment from an old waveform monitor.

Why?

Because as I had it on my bench powered up naked after running through a calibration on the CRT power supply, an operator comes walking in and rests his arm riiiiight here. Luckily I got him to move before any BANG occurred.

How do you even guard against awful human error like this?!

Small naked wire and HV diode are on the input side of a voltage multiplier that puts out FU Kilovolts.

Now if you’ll excuse me— I need to make a sign for him. 😉

Bonus: The resistor the other tech never bothered to replace. Amazingly it still works, but I wasn’t gonna leave it like this!

Crap Power Strips

This has significantly bothered me for a while.

image

This is one of the most common power strips available now, as it’s the least expensive available out of China. Note what happens if you miss just a little plugging in a two prong plug. If you touched the prong here and any grounded object, hi diddly shockarino, neighbor!

But guess who doesn’t seem to have a problem with this.

Genuine meaningless hologram.

This strip is available under a number of brand names including General Electric, Westinghouse, Belkin, Sunbeam, whoever the retailer licensed a brand name from that week. You should not buy it.

Is any of this real? None of this can be real, right?

image
No way. This must be the ergot talking.

I’m beginning to wonder if this city even exists or if this has all been a prolonged mass hallucination caused by ergot growing in the croquettas or something… Kinda like how the ergot growing in the bread in Salem led to the witch trials

There’s just no way any of this is real

Well if it’s hallucination it’s a really good one because dude I can smell the hot vinyl and feel the warmth from that bad crimp splice there that likely breaks about 23 parts of the National Electric Code

Panic exit is right…

No you won’t have any issues with people running out this door with your merchandise! The steel armored cables to the delayed panic exit lock control system will neatly land on and lasso the would be thief.
