B5-47 üç adet labaratuvarımda var 35 yıl boyunca kullanıyorum. hatıraları var arızalandı 2 si. El kitapçığına ihtiyacım var onarmak için bu konuda yardımcı olabilirmisiniz. Teşekkür ederim.

That final thesis is such a pile of horse***t. Any guesses why all the old building have giant antennas. The buildings themselves were the generators and capacitors. The antennas recieved the power from the draw stations. It's a one time cost to build and the infrastructure can be supplemented fragmentation to use amongst entire cities. This is a propaganda piece. Says all the right things and follows up with we must mine the rare earth minerals for solar and keep the farce that the windmills are anything but dangerous and maintenance disasters. Funny. May want to look how much crude, not veggie, not man made oils, but crude is necessary to maintain the function of a windmill. Then follow up the devastation to bird populations. Then add they can only hold so much power in their transfer cells that they burn through cells at an exponential rate because you cannot stop wind. This had the potential to invite creative minds to look past the propaganda, but instead tries to sell it. Good try

Eu vi um video russi que gerava pra duas bobinas teslas e fazia um barulho, aparelho antigo dizem que foi tesla o autor pena nao ter o link aqui...

paper of transfer thermal is the name of the papers use here

For all of you asking for the type of paper, search for "toner transfer paper" or "pcb toner transfer paper".

Great. Some what kind of Paper is that?

I like this little monster! If you cover the decimal point with black paint inside the display, then the reading on the screen is millivolts and no more confusion. The dropout voltage of the LM317 determines the highest resistance that can be measured. For 100 mA current, the highest resistance is given by the equation Rmax=10*Vin-30. For 5V, you can measure up to 20 ohms. For 9V, maximum is 60 ohms. However, power to your resistor is W=R/100, so heat will change reading. A 60 ohm resistor would receive 0.6W! But that isn't possible with a 9V rectangle heavy duty cell, they instantly drop to 5 or 6 volts under 0.1 A load. Alkaline cells would drop to about 7-8 volts under the same load.

hi friend...this is just sleyer exsiter with protections

На хорошей термобумаге куда быстрее получается!!!0

tried. But my transformer has 2 coils winding in opposite directions and ennd at 2 different pins.

what is the outer wire size?

If the capacity is 2200 or more mah need every cell 3.7v bms. And another for full wave ones so it could balance every cell so there's no way it will discharge in charge cycle easily m

Great project. Could anyone specify the secondary of the welding transformer (TR2)? How many volts by how many amps? Thanks

Thank you!!

Fluke 25...?

This is the BEST video on ATX PSU conversion on the internet. Well done @kasyantv! Years ago, I modified an old ATX PSU, making Voltage _and_ Current adjustable, following to this video. This PSU has served me well for many years (and it still is). Adding buck converters is for pussies. This conversion is super cheap and solid. Any good electronics engineer should be able to do it.

Send me pcb diagram circuit plaese🙏

I made one of these back in 1982. Photons knock electrons off of the aluminum foil and electrons flow from the ground into the capacitor. That’s all there is to it.

Unless I am mistaken this is the circuit diagram available from early LM317 datasheet - 5A Constant Voltage / Constant Current Regulator with a few tweaks like using two pass transistors, 25 turn trimpots to trim Voltage & Current pots. Looking forward to your explanation of the circuit design & particularly how the current control loop works! My real curiosity is the purpose of the small stand alone circuit in the right back corner (behind output).

Is it possible to make 4 of that battery and connect it together in parallel to create a 96Ah Battery?

Do you have a video showing how to separate the 24v output from an old printer power supply to use the said output for other components that needs 24v power supply. Thank you.

Face reveal plz

I got like 6 unmarked USB. If you need one just hmu $5 for just one

bms , charge controller and some hi power battery amperage

thank you, it is extremely rare i make comments on UA-cam but i really appreciate your review very detailed and extremely helpful, well presented thank you, i have been restricted to a wheelchair over the last few years and my mig welder has sat there for years not used as it just way to big and even on wheels it just not practical, and this sort of welder looks to be the sort of thing that i can use, that is easy to move about light and i will be getting something similar, the sip T1400 and will be looking forwards to being able to do some small welding jobs again. you are a star thank you so much i wish there were many more like you, you made clear all the info people could want, i would suggest maybe if you do any follow ups or similar items you demo welding a couple of bits together and show how well the weld reaches in to the metal, i know you said you are no welder but many people that have never welded will likely watch and be interested in how easy or hard you find it as a novice. anyway take care and thanks again.

Your PCB is very beautiful ;)

Great modification

6:39 " to fully open" -> to fully close. This voltage, here 10V, is the voltage you need to reach 0.028 ohms between S and D. This is not the usual voltage, wich is 3,5V with the IRFZ44. Also, it can be considered like the maximal voltage applicable on the grid.

Squematic???

Hello dear I need this one side PCB design please provide me

my first project i made

plz make with n channel mosfet

can the pin 3 of the 494 be un used?

Squematic?

💪👍👌🙏💐

what is that for a paper? What is the name and from where can I get ?

if u connect a joule thief circuit between the antenna and load, the voltage and current both will increase

Hey, I would like to ask for the formulas on how to of a half-bridge transformer calculations, thanks.

Where can I get the same original igbt that your using to buy please add a store link

Well done very impressive, I wish I had the understanding of electrical components you have 👍

Does any inductor have too much voltage or current across the copper coil,is it dangerous??

Some how forward topology work better then halfbridge converter topology I had the same issues when I made my first smps welder but a voltage feedback can be added to allow the halfbridge converter topology to work properly 37% duty cycle 62 voltage and at 50% full duty cycle the voltage with go 100 volt so the welder dropout voltage with no be 15 voltage but 26volt

Also this happen to me, Brand YIHUI

Please explain what the duty cycle is when there is no load on. . ./ . . . standby I use this scheme. but the igbt and mosfet get hot and explode in 15 minutes without any load.. Thank You

9:22 what are these aluminium clips called to screw the transistors to heat sink? i see them every where

Creative video, thanks :)

Where do you get original igbt transistor to buy I need a lot of original igbt for my business
