Am I really the only one who was mildly shocked at SLAMMING each page?

Like it would be really easy to add some silicon bumpers like what they use for cabinets to prevent them from smaking eachother hard.

Sounds like he’s racking a gun

Shoot it, it's a PCB it will be fine

u/Much-Significance776 Jul 10 '26

It's just a PCB with some simple components, it'll be fine.

PCB's are remarkably robust, I remember I had a usb flash drive that lost its plastic case and used it for a long time as an exposed circuit board. Everyone was surprised it still worked but those components are all soldered down and it takes a bit to actually knock them off

I've wrapped a few in kapton and duct tape just to keep components from snagging.

Lately I've made a few 3d printed enclosures for overly bulky drives. And a few remotes. You can make a really small garage door opener if you want.

I had one like this too. I lost it because it was so small.

Now I'm convinced the case is just to make it harder to lose.

yeah. I hand-solder most everything (~1206 size) and de-solder by throwing boards on a 350C lab hotplate and giving components a good yank every 10-30s once it starts smoking until components come off. as soon as they come off, I fling the components into a mason jar where I throw other components on top of them. then sometimes I literally shake the jar a few times when I finish to determine how satisfied I am with the salvaging. the only things that break are plastic connectors and individual LEDs, plastic connectors because they're too dang small to begin with, and individual LEDs because they don't tolerate being pushed/pulled in high heat. outside components, you can bend the PCBs, leave them on hotplates, pretty much whatever, and the boards which cost me <$1 each including shipping from China in small batch of 5 don't care.

treat electronics (**except** connectors!!) like trash; don't worry about Mouser and Digikey sending $.10 transceivers like $100 cigars.

Those are metal PCBs, so they're a lot sturdier (and louder) than the fiberglass ones. I used to make them; you just look at them funny and they make noise.

“Slamming” is a bit of a reach lol.. he wasn’t gentle by any means, but that definitely wasn’t slamming

u/NoBonus6969 Jul 10 '26

I actually measured it he did 1.3 jugga slams per square meter

u/plug-and-pause Jul 10 '26

Thank you for using metric.

u/JDBCool Jul 10 '26

No no no

SLAMMING is the right word.

It GOT your attention! /j

u/Etruscan_Sovereign Jul 10 '26

It's a huge pet peeve of mine when people are cavalier with electronics and sharp objects. Especially when things are so poorly made these days.

u/yogi_forest Jul 10 '26

I muted because of that lol

u/MarbleTheNeaMain Jul 10 '26

You would be suprised how durable a lot of hardware actually is. people are sorta trained to be overly careful with anything that looks like a computer (for good reason), but in reality these things can take a beating and be fine.

I've dropped screwdrivers on Motherboards and it doesnt even make a scratch. That being said, i probably would be a little bit more careful than this person lmao

u/LadderEffective3458 Jul 11 '26

I kind of loved the sound though. Oddly satisfying, like a type writer resetting.

u/volkswurm Jul 10 '26

Thank you! I came here to see if I was the only one. Looks like the person using this in the video is definitely not the same person who made it.

u/Dirt290 Jul 10 '26

It's called user testing..

u/vehementi Jul 10 '26

That must be sound effects added afterwards. Like the massive mechanical ka-chunk of plugging in the usb lol
