The first time I saw the light I thought I had dead batteries 🤣 but glad it worked for you

Todo iba bien ,hasta que vi 10:21 como destrozar una bobina por no saber sacarla bien,me parecías un niño desesperado,la próxima y debería saberlo ,la bobina es muy aprovechable también para ese uso u otros tantos ,salía muy fácil y si necesidad de violencia ,tiene dos sencillos métodos ,darle calor al núcleo de hierro por la cara opuesta de la bobina y solo unos 150° ,la bobina sale fácil y limpia y otro sistema muy bueno,sumergirla en agua hirviendo unos 10 minutos mínimo,éste es el mejor y preferido para casos similares,usted le da valor a una bobina y rompe la otra ,es absurdo 😂pero ambas cumplen la misma función en su proyecto ,solo con variar los voltios y potencia ,ambas funcionarán ,lamento tener que decirle que usted rompa material que otros valoramos en aprovechar y menos a la gente que ignora la materia y esté mirando su video ,cuyo título sería mejor "Voy a destrozar una bobina de microondas"

What difrint 331/331H

Good quick overview, although I did not get the impression that Schematix spent much time with the device. Some things I noticed with mine (100MHz version): - Yes, the included BNC-to-BNC cable(s) are not to be trusted with higher frequency signals, also they are unreasonably short - The integral frequency counter says that the device's own generated sine waves are 56.9% duty cycle (which also appeared in this view, but was not commented on) - None of the buttons on this device are "Tactile". That term should be reserved for buttons where the user can feel the moment when electrical contact is made, such as ones that have a "click" or other tactile feedback. - My device also still had the label over the piezo 'beeper'. My guess is that the manufacturer might be leaving them on to keep the beeper volume a bit more muted, because while the user can defeat the beeper entirely, there is no control over the volume, and it might be annoyingly loud without the label in place. - Having to set potentially long numerical parameters one digit at a time (instead of with a keypad, which this device does not have) quickly gets annoying. And the knob, being without knurls, and pretty shallow, can be a bit more difficult to turn than it should be, and it has to be turned a lot during operations. - The manual, while better than with most Chinese equipment, is hardly "comprehensive". A LOT of important things are not even mentioned. The more one uses this device, the more issues with the manual get noticed. One example; no mention is made about how to properly exit any given screen or menu. For the most part, the CH1 or CH1 button can do this, but it is hardly intuitive. But overall, this unit offers a lot of bag for the buck.

Where is place I want

tanks bro👏

Inductors

Dont worry tuching that transformer is not dangerous i did it lots of times.

Great. I want to make my own isolation transformer (220<->220) and first I thought about winding my own, but 220 turns? it's gonna take me a while. Then I thought what happens if I take a couple of trash microwave transformers, take out the 220v primary of one and put it into the place where the seondary goes in the second transformer? I would get the same exact number of turns on both, so, 220-220v. So my lan is to use a metal ginder to cut the sheets and re-solder them, as I have seen in other videos. Doable?

I appreciate your video. I can tell you from experience that you don't want to get bitten by the rf of the output coil. I once was working on a commercial level final amplified for a hf transmitter. Accidentally contacted the wrong thing in it and was thrown back about 6 feet into a concrete block wall. Not fun. Made me much more cautious when working with HV HF final output devices for sure. Safety is always the primary concern when building projects of this sort. I like your pc board design, but, the main buss lans on the board could have been a lot wider and possibly topped with a copper sheet lan soldered to the tin lan on the board. This would spread out the heat and also carry a great deal more current. Anyway, a very well constructed design. Thanks again for the video. I find these very interesting and informative. Have a great day!

Amazing build and video

Admittedly it is cool, but 110 dollars is outrageously expensive.

Just got my Kweld spot welder today and I'm so excited to get it set up!

What cells are being used?

I got one of these and blew the fuse as soon as I connected it to my 12V battery, no output load connected at all! Anyone knows why? Faulty board or did I do something wrong???

So it looks like the screens are now too close, and when you push the button, the boosted energy is able to jump the gap. Maybe a smaller transformer would keep it from making the jump, but still pack a punch when the bug gets inside and makes contact.

Stupid video

Every time he say The Word "Pretty Cool,Right" Wake me back from my Imagination😅

Prices please

Very neatly done good job

kWeld - complete kit 169,00 € 🤣

Pod music was preme

This is a really nice looking station but what would the capacitors life spand be as you are charging and draining it at least 5 times you use it and i wonder how many months or years that cap would last

hi, how about make it the siplest one? i mean not using the additional power supply, but using directly from the power outlet, and supposed to be about 310vdc, please advise me wich needs to be modified? thanks. cheers.

hi, if using 12vdc then must use a transformer and it is quite a heavy and big capacity transformer, if I make a dc power supply directly taken from the 220vac power outlet (using a bridge diode and a capacitor and supposed to become about 300vdc), what needs to be modified? the size of copper and the numbers of the copper wires turning? and what else? please advise me, thanks.

I plan on trying it on the Attiny85 with HCSR04 and a servo.

What a valuable video! And in more ways than expected - the comedy bit was hilarious! Thank you. Did anybody suggest, that placing the filter behind the fan might add to the suction? I do wonder how much the dense charcoal filter hinders airflow, and whether there would be any trade off in ways of fumes seeping through the cracks (instead of passing through the filter, after being hit by the blades of the fan)?

Hi, I'd really love to know the width of your BB, I am converting my Giant, and its 73mm and I dont have that much thread protruding as shown at 6mins 20secs. I cannot get the aluminium cover nut on, there is not enough thread to bite on to. Also I have 25mm pedal clearance to the chain stay on the RHS but only 5mm clearance on the pedal to the LHS chain stay . The pedals are therefore offset by about 20mm to the right. There is no spacer on the RHS and the right cannot come any closer anyway, as the 44T would hit the chain stay. I see that you are not using spacer washers for the 2 x motor mount screws, so I am thinking your BB is 68mm. Bizarre that my BBS02B 750W motor does not fit correctly.

Why did you put the shunts back in? I've seen people remove them before, and typiically they just left them out...

I just bought this thanks that calibration makes sense now

Is it possible to mod the buck/boost trimpots to external rotary trimpots that are easier access outside a power supply case to make it adjustable variable

i have the same irfp4668 mosfet from old broken smps but i did not have than much component and power. so, do someone have idea to make induction heater with irfp4668 mosfet, 12v voltage rating and less than 300 watt of power?

Excellent presentation

Idk if I'll ever build one of these but I'm digging that funky disco music 😂

Would this transformer make a good inductor?

Parts list please?

Cunversion kut 😂

can you make it into a powerful perpetual magnet using the Edward Leedskalnin design ???

I lost interest in this video because I was forced to watch this stupid gimmic commercial first. Im writing this stupid comment now instead of watching the video although I can hear it while writing my comment. Great work you tube.

great video with lots of useful information thanks.

excellent video and the advertisement was watchable.

Thanks for a very informative video, well explained throughout. Your delivery is very good. Really really really really hate the irritating music, ruined the video, made it painful to endure.

Hi I think you don't need such spiral for only 2 MOSFETs. A 2mm diameter of wire with around 10 turnes over 1 inch tube would be enough

Great video. 👍

is the size/weight of the coil critical to the board? forgive me if you mentioned it. i havnt watched the vid right through

So in the commercial shut they are using different material with different resistivity per volume than copper, right?

❤❤

.. i just need it to Outrun the occasional Dog .. 🙄😳🚴‍♂️🚀

Thanks for the interesting review. I'm wondering if I can stack two PS modules to be centrally commanded by the screen controller, as a differential power supply (common negative) and/or a series arrangement, both for versatile electronic breadboard projects and teaching.
