[@KazemitoHaruhi]

quick tip for me if you don't know, preheat the PCB only on side you want to cut until warm or slightly hot to touch before cutting makes it easier to cut.. I have tried this multiple times with small scissors and works great

[@therealjammit]

I'll have to try that.

[@slavisastojanovic2303]

Can you leave montage pcb and real size picture of pcb with drawing?

[@jonlitchfield8888]

Please please dont forget to make and upload part 2, with circuit diag or at least clear image top and bottom. This looks really really nice

[@JustMe-dx5xl]

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).

[@JustMe-dx5xl]

Appears to be small seperate power supply, connection for NTC thermister & switching circuit ----------> Thermal Fan Control ?

[@nonesubham]

where is cad file??

[@sayeretmatkaal]

Why did you trim off that 6mm strip from the long side of PCB ? That was an unnecessary risk since you didn't saw or scribe the cut. But all the same, A VERY GOOD JOB AS ALWAYS ! Paka-paka !

[@anonymoususer6448]

I was thinking exactly the same thing... I guess a "risk" for you and me... but not for @kasyanTv 🙂

[@hichamtassi1753]

Hello Kaysan, thanks for that new project ! may we have the schematic to try it, also, can you make it 50v ?

[@ninethirtyone4264]

I have built a few designs around the LM317 like this, the issue is that the power supply requires a lot of current to be drawn at the output to regulate properly, and for small work this is simply not suitable. There are much better designs out there.

[@socialbeat2587]

can u offer me any circuit to make? I need a circut that shouldnt drop voltage when put in load

[@aliveli4810]

If you have a recommendation for a current and voltage adjustable circuit that works without using lm 317, could you please tell me?

[@wraiths_]

Waiting for thr next parts! Keep it up!

[@sefalibhakat143]

I was waiting for this..

[@muharremnisanci]

😮 very good , many thanks , but I wonder , is it necessary to run so much Water for cleaning the paper?😮

[@RAUF.Y]

where is part 2

[@damiaomendes2809]

Gostei da laminadora também pode fazer um vídeo ? Desejo os arquivos pra fazer PCb.

[@ekfariant3159]

Schematic ?

[@therealjammit]

This is part one. He normally goes into better detail by later videos.

[@ziyashirinov6283]

Great video. It would be better if you gave some information too.

[@srinivasraor770]

Dear sir can you please make a video on uc3845 to generate variable pwm

Your PCB is very beautiful ;)

[@rajeshmadiyapara9503]

Circui pls.

[@GemunuJayasinghe]

I am more interestad in your electronic videos. Please release the circuit diagram of this video . Thank you so much for sharing your technical knowledge . I am from Sri Lanka .

[@edmundoarteagacastro8523]

hello; Greetings when you release the second part, I'm interested in your project

[@GapRecordingsNamibia]

CAD and Schematic please Kasyan?

[@strelavarss9146]

Shematique???....and nice job

[@LuisMartinez-fn7nz]

Buenas mano me podrias regalar el esquemáticos porfavor gracias

[@TriunfoGim]

Where's the schematic?

[@denisiswan]

Можно ли использовать этот источник питания для правильного запуска электродвигателя? Я сделал такой блок питания из вашего предыдущего поста, но возникли проблемы с запуском электродвигателя.

[@RixtronixLAB]

Creative video, thanks :)

[@rajeshmadiyapara9503]

Waiting for part 2.

[@nfcradio4622]

Hi I am unable to make pcb using Tonner Transfer pl give some alternative cheaper method

[@IT.Athear12]

hi Friend Frist of All Thank you >... But how we can make A short Circuit Protraction for A Variable Power Supply

[@Edmorbus]

Can you share the pcb and the circuit diagram

[@bassreaper7779]

Wait for part 2. He usually provides all the information in later videos.
