#4 LM317 Power Supply Kit with Case - Modification / Build / Test 

The timestamps you put in your videos are just outstanding. It really makes your videos more useful. I wish more people did this.

I just got this kit and found your video and am so pleased that you removed everything I didn't want to be part of my project. I am new to this hobby and would not have been able to do this without your video so thanks for taking the time to share this with us and I look forward to watching many more of your videos.....

Thanks for the video, I really enjoyed it. Good presentation and an informative build.I will try this myself. Have subscribed. Good luck.

Dein Video ist Spitze, ich will dieses Modul auch nach bauen. Ob ich es dann auch brauche weiß ich noch nicht. Your video is top, I want to build this module also. Whether I need it then I do not know yet.

If you've already built it completely, can you just remove the IC from the DIP chip and therefore remove its current pull without negatively affecting things? Or will the other extra components mess things up?

Hi...cool video, thanks! Is it possible just to switch out the LM317 with an LM338 instead? Or does it need a lot more figuring out? I just bought myself a couple of these kits, but i hate to blow one up through my ignorance if i use LM338 instead. Thanks!

Hello, why you modify the original kit? does this modification gives some advantage? thanks.

can make phone supply?..like dc adjustable supply...for phone reparing..

is this a good one to convert into a tattoo power supply?- meaning add audio jack inputs?

what is the point a have all same results with complete kit...thanks anyway...how buy this kit but with trafo 12 v and 1A instead 150mA...so it is not low price...the price is equal to the amount of current it gives...to low

You don't have to take the wires off the display. I shortened mine and soldered them to the board. I left them a bit long because I put my display on some taller standoff's to get it closer to the top of the case. I am also installing a larger transformer that will give me nearly an amp of power rather than the 200 ma one that comes with the kit.

Can i use 3A/12V X-formar or 3A/24V X-formar?

Wait why did you remove those components? Btw I am really a noob to electronics. And also great video

What's the kits price.? LM 317 POWER SUPPLY.

I got one of these a few years ago now, I was quite disappointed as they sent me a transformer for 240 volt mains, and of course living in the good old US of A, we have 110 volt mains. I let it lay in a pile for about a year, when I tore apart an old stereo and found a good transformer that would do the job, so I replaced the wrong one with the right, and used it a couple of times, but I found that the rheostat was a bit too touchy and too easy to bump and raise the voltage over what I needed. So I have returned to my home built DC power packs that I built using 18650 batteries with step up and step down converters. I built these in small cases so they are very portable, and the screws for adjustment is well protected inside the case with a hole the size of a small screwdriver above each adjuster, and a meter built into each so I know exactly how many volts I am putting out. I have 3 of them that I take with me when we are in the RV, and bring back in the house when we return in the spring, one set at 5 volts but, of course, adjustable to about 11.5, the second is set at 12 Volts, up adjustable to 23.5, and the third built with 8 batteries is set at 32 volts, and adjustable to 94 volts DC which I use for outdoor testing of 50 and 100 Watt LED lights.

Is R4 the 100k resistor needed?

can you share the circuit diagram?

How precise is it ?

Can i have that circuit please ??

hallo, du hast aber lange Arme, :-) Hello, You have long arms, :-)
