วีดีโอ

I have been doing this for many years. I build my own R/C equipment and repair antique equipment. I salvage lots of diodes as Bonner Digimites use a lot of them and they go bad a lot. I salvage motors and gears out old toys. I have gotten servo chips out of toys like teddy ruxpin.

I always salvage 78xx regulators !

very nice information in this video about all application of TL494 ic.

Thank you. I'm trying to increase the voltage and amps in this cheap dc boost board that keeps blowing up. So from what I understand, it should work just the same if I increase the ratings of the mosfet and diode.

Excellent explanation. Thank you. Great help.

Fantastic info , no BS just simple facts thanks for doing video , well deserved sub

Thank you so much

Perfect video. I was looking for info about TL594 but it looks like this chip uses basically the same principles, so this will prove immensely helpful.

At about timestamp 4:00 is the common connection of the resistors connected to the bottom of the capacitor? There is no connection dot there. THANKS FOR THIS VIDEO...my first look at the TL494... --daLE

I find wire is a good score. if yyou buy cheap Chinese flexable copper wire its often rubbish that wont soldier. Good pointers and advise.

Interesting, thank you!

Great vid! Like and sub

now where do you think we can sell desoldered electronic component 🦍

"only take what you need for what your working on or plan to in the future" so hoard. Thanks. Now my family can stfu!

Omg thanks for the video. I like salvaging big flat screens off Craigslist and the boards I don't use and never will I always wanted to scrap the good components but I'm just learning about tech and don't know what to take. I figured I'd just take them all but meh

thank you soooo much man you are great

only idiot use used elektrolytic capacitors

Save all parts! One day they could become very useful, when the borders with China close down. Since there are no electronic component factories left in the free world, building something with electronic components can become very difficult.

mercy bro

What to desolder: literally everything except pin headers. Just throw the boards in a bin and desolder when you need parts.

Very useful and clearly presented. Thanks

Hi there, any clues on the PIN3 ? thanks

Ty Englishman.

I have a question for you sir i have many car amps and power bricks but dont always fix them as my knowledge is quite small compared to peoples like yourself how did you learn so much and get into it

a yes i do love using old tvs and transformer for my deadlift training, good video its always exciting finding some odd device and taking it apart to see whats inside and what can be used, i prefer switches and relays, they can be always usefull

I always find interesting things in trash. I found a 90s pc last night. Some of this motherboard capacitors are dead, i Hope to replace It from another found TV or similar boards! If not, i Will buy it

I have always understood the 'Dual Resonance' part of a DRSSTC to be matching the inductance and capacitance of the primary circuit (which indeed, as you pointed out, should resonate at the same frequency as the secondary + topload + streamers) such that the impedance of the primary circuit consists only of the resistance of the coil wire and the ERS of the capacitors; the reactance is thus equal to (or nearly) zero. You pointed out that having your reactance too close to zero results in (often dangerously) high current, but didn't really mention the connection between this effect and the efficiency gains that this "dual resonance" affords. One way to "beat" (pun perhaps intended) the high current is to use an interrupter circuit to ensure that current does not get so high that it leads to catastrophic failure of the driver switches; one needs also to take precautions that 'zero voltage switching' occurs within the driver (or again, the switches - MOSFETs, IGBTs, etc. - will be destroyed).

too lazy, best i got is a bin full of motherboards and wire bundles

I save the plastic shell from any powersupply I'm tossing. They are great for little projects.

POV: most of these capacitors cost less than 10c/piece so you could really buy it, there's not much chance you'll need the exact type, also they do in fact age and dry out.

Scavenging at its best

Lmao i lost it on the last one 😆

I got lots of funky ICs while stealing from junkyard

The non sensical use of lead free solder to save the "enviroment" is beyond stupidity or is it. Throw away electronics needs a built in fail mechanism .

I simply collect heatsinks at this point in my life.

Very nice! I am currently working on a high power 5000W synchronous dc to dc boost converter system and I am planning to use TL494 as well. Great video. Success wishes! 👍👍 The Innovati0n Lab💥

I geted from pc motherboard wholly VRM and it works

yeah i havw everyting you said

bro i have more components and i dont now what to do with them like a relays capacitors and my favourite and hard to achieve is a diode

..some "great" directives!

I was fortunate to get to scavenge from a vacuum spark sintering machine from a metallurgy lab, and the other equipment too before it was scrapped, found some amazing transformers in the sintering machines spark source, a 25kv coiled core with some strange red bitumen like coating, its gotta be from the 80’s , im still working on firing it up as soon as I figure it out, regular wave inputs get little effect but the pulse when tapping it on a battery gets a crack of a discharge. Not sure what class of transformer it is, the internet is not helpful regarding its identification. Got a beautiful induction coil setup from inside a sampling type of machine, big amplifier tube, many fantastic capacitors to suit, a few proper spark gaps, some of the most boring looking machines have the coolest parts

Anything with spooled magnet wire i keep, not a shred of copper slips through the cracks, if its conmon transformers il strip em and add the metal to my pile. The pcb mounting thingys that ne555 type chips plug into i use often, made a habit of setting every gold plated pin aside to be harvested oneday when i feel like doing chemistry again. The 1kv and up ceramic caps i keep, enclosures i keep, plugs, bizarre components i keep, 12v relays , fasteners as you say. Potentiometers and any other variable components, antennas of all kinds, rectifiers that can take abuse, any vacuum tubes or bulbs besides common ones

What happens to the back emf at the primary when the secondary is shorted

Thx.

just weight traning part :))))))

"Before you take the LCD" . . . you should probably learn the difference between an LCD and a VFD.

I like to salvage fans, stepper motors and DC motors and 8 ohm speakers. Even microservos if they are in an old robot or toy. Big caps are always handy for audio speakers and induction coils for the same. I also grab mechanical switches and dials and sliders (rheostats?). All good stuff. Great video.

Thank you for this informative video. There's a little mistake in the title or the avatar of this channel. The avatar shows an orangutan but the title contains the word "monkey". Technically, orangutans are apes, not monkeys!

You should be using bigger transformers for weight training

If we don't have scarcity of spaces we can always keep electronics and other technological products. Theses are best engagement of time and learning differentiated latest version of technology.
