No I didn't I can try it with the heater element.
Heater is 220V 1KW
I understand the risk so I will not do it.
Ok.
Yes I accept all your advices and I will take a care.

Please if you give me an example of some boost converter circuit diagrams with high power?
It can be based on...

I understand what you tell me but I am a beginner.
I have assembled some simple circuits based on NE555.
I don't make PCB's.
I make drilled holes boards from wood (like Turret board) and I connect the components by wires and clamp wire connector.
I solder the NE555 pins to wires.
For...
Yes I assembled it and I connected it on 220V incasedent bulb just until 60 Volts and the bulb shines a little the voltage normaly drops until about 30 Volts.
No I don't have I am a beginner but I have made some simple electronic projects already.

I already assembled NE555 buck boost converter so I can generate about 60 Volts and 5 Amperes from +12 Volts power supply. It should be aboout 300 Watts of power.

I want to drive a Piezo Horn connected at four BJT NPN and PNP transistors bridge circuit.
I have circuit for driving it but I can drive it only at max +12V power supply.
I want to drive it at full power of 150W or 300W.
By my calculation for Piezo Horn
P=150W, V=35V, I=4.28A...
I have just this type of diodes at present in my boxes I think I could use them but I cannot use full current power from +12V outs of supplies. I will need to buy stronger diodes about 20 A.
I will describe the application I need them for it.
No it is not paralleled it is my mistake here is the correct diagram again:
I made mistake by using this picture:
And I made mistake using this picture:
I have two old regulary working pc power supplies.
Is it possible to connect this two power supplies +12V outputs and Masses in parallel
to have +12 and more current from both ones?
Blueberry PSB400
JNC
MODEL: LC-B300ATX
I want to connect them in such way:
+12V output of first one and +12V...
Thank you for the answer.
If I decide to buy it can somebody at this Forum turn it to be voltage adjustable.
If I decide to buy it I would send it to address of some electrical enginner firstly to integrate a variable resistor to make it adjustible.
If You or somebody accept it?
Because I am new is this good solution to buy

It would be dangerous for me as a beginner to experiment
with X2 capacitors and wall line.
