Capacitors often fail short-circuited, so even if it's just a filter, if it's bulged replace it. Also having live voltage on the heat sink is very suspicious, usually on the power mosfets used in these power supply the heat sink tab in the TO 220 package is connected to ground, not power...
@@HMan2828 If it is a push/pull setup with centertap either setup of case being Source or Drain can cause supply to be on heatsink depending on polarity.
@@HMan2828 Live heat sinks are completely normal and very common in switching power supplies. Here it is likely connected to the Drain of the mosfet. Even if it was connected to circuit ground, you can still get a zap off it because circuit ground is not the same as earth.
Love the videos man keep it up!!
I've got a question for you and I'll ask AVE the same one.
Is it possible to store static electric build up in a batery pack? I ask because I finaly got the media blasting cabnit to stop shocking the piss out of us at work and I thought what if instead of grounding it out to the maching you dump the charge into a rechargeable batery pack.
Immagen, you're blasting and at the same time you are charging you phone or drill packs or some AA batteries for the ol' lady
What made you mount it on the outside vs inside?
Awesome chlorate cell, that's a really nice clean crop of chlorate you've got. Can't wait for the video
I come for the science and learning about amateur chemistry but I stay for the analogies.
Never has toomas and Michael J Fox been placed in a funnier context 😂😂
I litterally just did this to my Amazon Portable Fridge... Used an ATX and it works like a charm.
Never heard of a chlorate cell but I know what you're up to....
I had the same problem with mine, changed the capacitor and fixed!
I would say there is a decent chance the power supply can be fixed by replacing that bulged cap. The control IC in a switching power supply can detect many types of faults. With the dead output cap, you likely get a very spikey output voltage which will be measured on the feedback pin of the IC.
That little potassium chlorate cell caught my eye....
Ok, you were LITTERALLY looking at the problem! That bulging cap on the switching power supply indicates that it FAILED. I've fixed about a dozen of these things over the years and, except in one instance (bad peltier module), the cheap quality output cap on the switching power supply is the problem. If you hear the switching power supply "ticking", that's the first place you look. Instead of going through this whole mess of wiring up a new supply, you could have fixed it with $3 worth of quality caps installed in the supply.
I didn't think it could have been that easy lol. I think I still have the board so I may have to give it a shot and see if a new output cap fixes it.
@@ElementalMaker Yep, it's THAT easy...lol....if you hear a ticking sound coming from the switching power supply and you see the caps are bulging remove, replace and done. The cap is essentially shorting out as it tries to charge up. Everything else on the supply seems to hold up just fine....a few more cents spent on better caps would prevent the problem in the first place.
I’ve been having the same problem, turn it on and the relay continuously clicks, and I can hear a sizzling sound coming from the Switching power supply, the top of the cap on the output is a little bulged, I’d appreciate a reply about what I should try replacing and what the sizzling noise might be from (I don’t see any corrosion or anything got hot or loose)
Shit never ends. How true bud. It is great having a safe power supply. I have one to power uhf/vhf radio transmitter/receivers I work on.It is always fun to see you dive into anything that comes your way bud !
Good job! Nice simple troubleshoot & fix!
Keep on keeping on!
I fucking laughed for a good half of the video. It's always great to hear from you man!
You think that Macgyvered temporary power supply abortion looked bad? Brother you had it easy. My laptop hard drive went bad and it wasn't your standard laptop hard drive size but Some little weird 1.8" hard drive. So I have a full sized sata drive going into a sata - usb cable plugged into a computer power supply i had floating around here. It is Jankey as F. But it works. :-) Keep up the good work!
Get yourself some of the acrylic based glue sticks. They require a "high" temp glue gun, and I've never seen them in the mini form factor... but they provide much better adhesion and tolerate a wider temperature range without failing.
You can also get the tan colored industrial grade sticks, they are even better. Unfortunately, I was gifted my supply of them as a large handful of loose sticks, so I have no idea what term(s) are typically used to refer to this type, but perhaps someone more knowledgeable than I can chime in.
now that was fun.. you sound like me explainin' to the kids why my life is so hard!!! outstanding! I have to go and check out other videos
Glad you enjoyed! 👍
@@ElementalMaker oh heck yeah.. much better than most I assure you.. thanks again!
Dead caps cause the tick and high esr on the output, or in the feedback circuit, cause the power supply not to regulate. Could be just that output cap, but if one is gone chances are the others aren't far away either. A decent proportion, if not most, don't show any outward sign of failure when their esr goes high.
That one cap may just be filtering but it also forms part of the feedback loop, it's failure will cause the smps to fail.
They sell a 12v cooler heater from road pro. Coleman also has some nice ones. Simple power supply would run it off ac
I tried messing with peltier chips last yr, tried cooling a ccd camera with one modified a computer chip cooling fin and fan setup and almost cooked my ccd camera, Im going to try it again without he camera attached this time, Id love to build a box for my dslr one day
I would not be surprised if the fan is the same as a microwave fan.
casually switches smile.amazon to elemental makers link...
Much appreciated Zack! I am going to look into a way to incorporate the Smile program into my affiliate account so that charities will still be supported.
@@ElementalMaker ahh the patreon money is probably far more than you'd ever make off my amazon purchases, although setup an account at aliexpress and id make you a rich man. While i'm at it bit of a long shot (pun intended) but would you be interested in having my 50% employee discount for sig sauer? I'm a professional cnc button pusher and we get 8 guns a year at discount it resets in january and I still have all of mine left offers there if you want it
I truly appreciate that offer Zack and thanks so much for your support on Patreon! I'd love to get myself a Sig but with house renovations and my safe already overflowing the wife would kill me with it LOL That's a sweet deal though I might have to reach out in the future when funds allow!
I did enjoy your video,
Thanks man!
wow beutiful chlorate cell, nice huge crystals, never had the need to make my own yet
I use a lighter for heat shrink all the time. Gotta keep the flame moving.
Hello, great channel ! Keep up the great science. Where can you get those machined aluminum tamping posts, nozzel maker, and end cap set you had for making the engines.
Have a wall wart with enough punch but not the right voltage? Use a buck/boost converter!
Sooo many things I can't comment about...but so funny
😂😂"they'll slap anythin on there to make you buy it"
Have you thought about high performance RDX propellants. Look on the science madness energetics board for help
I have an AstroAI 4L mini-fridge that has some sort of fault. If I turn the fridge switch to the warm side, the warm LED constantly flashes and the fan stops/starts constantly. I can hear a constant click sound that matches the LED flash. The cool side seems to work. The LED stays solid and the fan spins.
Any idea what might cause the warm side to behave like that?
I don't think I want to do any thumbs up near any dingleberries.
There is a vacuum curing oven on my local Craigslist (Dillsburg/harrisburg) for $125. I think that would be brilliant for your purposes!
Damn that's an AWESOME deal!
@@ElementalMaker If you checked out the link, it's a real scientific piece not that your current option isn't effective. I also know that you're not terribly far from my area.
Baking soda and superglue??? What's the baking soda for?
I'm with fixing the oven, but what's the hurry? At the proper ratios, R45 and isocyanate cure at room temp.
Issue is my garage is at outside temp. No heat or cooling
Hi I have the same one and I want to know if it's work always with electricity or not
Why don't you put the power supply inside the unit?
"...that way in a couple of months, it'll fall off and make me curse and whatnot - Ya gotta keep yourself on your toes".
Way to out Bumble-Fuck Uncle Bumblefuck! Admit it, you're his long lost son, or brother, or uncle, or ... something *suspicious face emoji*
I've been using the baking soda/super glue combo for years. A big FYI.. as convenient as it is DO NOT keep it in your car in a empty pill bottle.. Cops throw a fit over it!
Are little zip lock baggies better than pill bottles wrt the police? 😇👮
9:48 OMG!! How Beatiful mate well done! Where did you got the MMO Anode?
Thanks! Got a bunch of mmo anode sheet on ebay
ElementalMaker hhahahah nice👍🏻
wenn the output ripple is to high, the feedback cirquit goes to shit... dosnt it?
Put that hot glue RIGHT NEXT to the heatsink. 😆
Super glue and baking soda mix to make a miracle substance.
Doin a little of the Michael j fox 😂😂😂🖤🖤🖤
Lol " I switch it on and it goes all Michael j Fox twitching and clicking and f,,,ing around" great repair, less than half the amp draw ,,,, should go for years. Mmmm propellent have we got a flying and or blowing up video :-) cristills? Crystals? Potassium chlorate looking good.
Why not just put the new power supply in the same place as the old one?
Good stuff, when are we going to build a big rocket and fly it to the moon?
Btw, what is that company's exact website so I can inquire
Sooo what were we hiding on our key chain??? Hmmm??? Or do I really want to know?
That was my swipe card into the local ladies ballet. Didn't want any of them recognizing my hands 😂
@@ElementalMaker Lol! Thought it might have been your customer loyalty card from Butt Plug of the Month Club!...
I love that kind of strippers, they only sucks when they get clogged with the insulator
They sell the heat sink and peltier assembly on the wish app 😆
Yessir! I have a few of those and they are fun to play with.
@@ElementalMaker I am actually collecting parts from wish to try and build a peltier based cooling vest using cpu cooling parts.
Why not just remove the old PS and put that power brick inside the back in that location?
I didn't say in the video, but the new power brick was just a bit too large to fit
@@ElementalMaker Yeah... I was thinking that after I posted.
We've probably bought MMO from the same eBay seller
Laserred let me guess? Great seller. I bought back when he sold them in big sheets so I have a WAYYY overkill lifetime supply. Anytime I need a new anode I just use my buddies big sheet metal shear.
HAHAHA the MJF comment... amazing! ((btw to the keyboard warriors out there... I'm disabled myself - and that's NOT offensive in any way! LMAO))
It's not a toooomaaah !
Yeah thinkgeek sold out to gamestop.... I wish they’d just died with dignity instead of selling out to the worst blight on gamers since EA. As if they needed yet another way to take a big dump on the gamer community before they became completely irrelevant due to the obsolescence of physical game media. Now we all get to watch as they rape the corpse of the brand that first made our cubes fun and gave clueless moms a place to find stocking stuffers we actually wanted. RIP thinkgeek.
Any decent aftermarket computer cooling fan (squints carefully) should fit there. …And create less noise. 👌
Am i from the future
Welcome to the past 👍
AVE wanna bee??
Even Nikola Tesla the dude who was responsible for making sure electricity was available to the masses throughout the world was somewhat of a plagurist, he got the original idea for his ac motor from a scientist called Daniel Cook.
That being said your comment takes me back to that saying "if it ain't broke don't fix it" they are both pretty funny guys who like to play on words but that's what you like so you'll be back for more.
@Pablo Damon even if, where’s the problem?
@@among-us-99999 What problem? A hypothetical problem that you might point out?
I think you could distinguish or differentiate yourself from Back To The Future nerds, or nerds altogether, without throwing low punches to a man who was victim of a stroke...
