May I ask if its possible to have an output voltage of 0V to 30V in this kit? I hope you may notice my comment since this video is 1 yr ago already. Thank you so much!!
Thank you for the video. Got the kit, but the instructions are unclear for n00bs. 200 mA is not bothering me, I need something to test the soldering training kits, as they are powered from 3V - 12V. Usually I need to find the right power supply to just test, which is PITA, to see if I botched up another soldering kit :D
Hello, I have the same kit. I am troubled by the Green and Red Led Just dimming while the power supply works. Is there problem in the schematic? Like how the schematic is built. Because all my components are connected properly.
Stefano, what do you think of this e.kit overall? I bought a geiger counter and it was a fun project to build. My only micro gripe was the annular rings on the PCBs were tiny which makes it harder to solder to for a rookie like myself. :) I want to buy a proper adjustable lab power supply eventually but in the mean time I wouldn't mind building one myself. Do you thing this kit has enough juice? I notice it has a very low output amperage of what 200 mah? Is that going to be enough? Right now, I'm just building kits from ebay, Amazon, and AliExpress.
@@Stefano91ste Okay, its seems now its obvious. low amperes means limited in what I can power. Hmmm. I noticed too late that this kit you build has a fault. The 4 digit display has pcb with wings. The wings have holes but the main pcb has no holes for bolts which is bit crappy still everything else is good. It has a very acrylic case which I like. Pity about the 4 digit display just flapping around on three wires. I dont know why they didn't do it properly it could have been the best mini psu on the web. Anyway, when I get mine (Monday I hope) I might get some solid copper wire to solder it to the pcb with. Thanks Stefano, your a protectionist and take a great deal of pride in solder and making great content. That must be very time consuming. 😀👍🏻
Thank you for your work Stefano, I really hope you have as much fun making these as I do watching them. There is only one thing I cannot find on your channel.. an amplifier clipping detector LED! Is it possible you could make one? That would be awesome, as I want one in my car! Have a great day :)
Hi, thank you so much for appreciating my work on TH-cam! - you are right there is no clipping indicator, in reality there are still many projects that I will have to carry out, as I have time and more and more experience =)
@@Stefano91ste I hope you can make one soon.. I would even pay you to design it if there was a way! I am glad to hear you have more ideas for the future:) Keep it up, greetings from England 🇬🇧
COntinuo a rimanere affascinato dalla brillantezza dei colori dei tuoi video :-D Domanda: non c'era un foglietto di mica per isolare l'integrato LM317 dall'aletta di raffreddamento?
Ciao, non hanno messo nulla.. credo anche per contenere i costi, perchè poi si sarebbe dovuto usare anche altro per isolare la vite e non potrebbero più vantare KIT a basso costo :)
The yellow, red and green LEDs are like a small status indicator, of the part of the circuit that generates the signal for the tests (the circuit is a PSU + fixed non-adjustable signal generator) :)
@@Stefano91ste oh Stefano, again, thank you so much for taking the time to try to explain what those lights are for. I was reading last night about amplitude, frequency, sine waves and what a hertz is or maybe that has something to do with it. Anyway, I'll keep studying and try to understand the fundamentals of electronics. I've only just started to teach myself electronics which of course means I got a long way ro go before I understand and and appreciate what all these other gadgets do like "signal generators". 👍🏻😀
Très beau Kit mais il n'y a pas d'isolation sur les fixations du transformateur (vis + écrou), le transformateur n"est pas relié à la terre (chassis ground), il y a un risque extrême si il y a défaut du transformateur, en terme de sécurité. J'adore vos vidéos. Un bonjour de la France. Traduit par DeepL. Very nice kit but there is no insulation on the transformer's fixings (screw + nut), the transformer is not connected to earth (chassis ground), there is an extreme risk if there is a transformer fault, in terms of safety. I love your videos. A hello from France. Translated by DeepL.

What components should I replace? Thank you
Hi, no the output voltage is from 1.25 to 12V DC
@@Stefano91stei need output 5v-12v not 1.5v -12v this kit? What are changes should i do hehe? This video are 3yr ago please answer may question ❤
I have the same model as yours,,but when i finished assembling,,the output is too high,, between 10v-14v,,what is trouble shoot for that sir

The diagram is printed on the board. Just use that.
Solder small components first.
Nice kit
Thank you =)

@Ivan Petrov Hi, without load the power supply works correctly?
@Tomáš Mark During normal operation only the blue LED remains on, the others flash.
@@Stefano91ste with and without load they are Just dimming.
That's a nicer enclosure than the cheap nasty one I got from Banggood!

Can anyone do a mod so it outputs 1A and runs off of a 12V adapter?
Quality final solder! If you are looking for an even higher output-current bench power supply, its better to convert your old PC power supply.
hi may i ask why my 7 segment not working?

Do you know why i can't go down than 12v ?
Hi, check that you have assembled each single component correctly, and that there are no incorrect welds in the area of the potentiometer
Thanks, now i (probably) know how to use that 3 lower connectors.
Saludos mi amigo my freind!!! Desde Buenos Aires Argentina!!!
Gracias, saludos a ti también =)
Hi, is there somewhere I can get in touch?
Hi, you can ask what you want in the video comments
I'm new to electronics. My green LED doesn't light up and it bothers me. Though the power supply works fine.
Great Sir......😊😊😊
Sir, please make a automatic water level indicator with auto pump on/off including 35 amp rely for heavy load circuit.......
Thank you! I'm going to do something like this soon
@@Stefano91ste Thank You So Much Sir for your precious comment......
Stefano, what are the three LEDs. What's their function?🤔
(Hmmm your not up yet.) Enjoy your sleep.😂👍🏻
HI😁 the LEDs are Power (Blue), Signal (Yellow), while Red and Green indicate High or Low, referring to the output signal generated by CD4069
@@Stefano91ste oh, um, okay, not that I really understand what that is. 😂 thanks anyway for taking the time to try to explain it to me.👍🏻

Hy, You are right, it would have been better to fix the transformer with plastic screws.
Thanks for appreciate my videos, greetings from Italy! =)
My volt meter didn’t come with the wires and my kit also didn’t work. I made sure I did everything correctly.
200mA...?✌️😁🖖🏻👌
Yes, it's not much, but all in all I like the KIT😁

@@Stefano91ste is there anyway to increase the 200mA?
Good good good
Thanks =)
I also made this but I don't know that it can only output 1.5amps . I've connected a 3amp load😂😂😂.burns instantly 😂😂😂😭
Woow xD
Maybe just replace LM317 and it is as good as new
