LFC#206 - Bench PSUs and stuff you can do with them

[Links to these PSUs down below] Been asked to show a more detailed video about how I do voltage injection, but before I post _that_ video I want to make sure everyone understands exactly what a Bench PSU can do. It's essentially just a variable voltage output, but its ability to set both voltage and current limits give you a great deal of control over power delivery.

Im so freaking happy I discovered this channel. This guy is incredible. Not only I’m learning quite handy things, but I’m also enjoying the process since this guy is really likable. Instantly subbed. Great content, sir! Love it!

I just love this guy, Adam I think his name is, I am 70 years old and have a great interest in pc repairs, I love the fact that there is no annoying music, his explanation is easy to understand. Watch all of his videos, liked and subscribed. Cheers from Ireland

I think this was the _most informative_ AND _easy to watch and understand_ video on power supplies I've seen. I love the way you presented it and the verbage you use to describe things resonates very well with me. Thanks a lot, keep it up!

I'm just getting started tinkering with electronics and bought a $40 power unit from Amazon. This video was extremely helpful in learning the basics of how to use these things and what they are capable of. Thanks for the great video.

You're really the only one that I've seen that's done a proper review of the HM305P. You're the one that's knocking me off the fence and ordering one.

Just excellent video - Thumbs up on production quality on: audio levels, lighting, camera and content. Thumbs up and subscribed.

Thanks a lot for this video, I ordered a 10 amp model of the one you have and the output toggle is a huge advantage and I just love the unit a lot in general. I guess I was just spoiled by the expensive units my uni had and didn't realize that some features didn't exist on the cheap end. I was about to buy the cheaper one before but glad I didn't. Also discovered this great channel and have been binge watching for weeks. Long time ago I ordered a set of laptop plug adapters which came in incredibly handy for the bench supply as I can just have a single 5.5/2.5mm barrel jack on it and plug any of the adapters into it to turn it into any laptop power supply socket (apart from USB-C and the flat lenovo one I guess)

This is a nifty channel, thanks for all these tips ! It's nowadays rare to see a channel putting up non-nonsense content so I'm happy to have stumbled upon this series !

Ever since you talked about your soldering tools specifically the PINE-64 I immediately ordered it thru Aliexpress and since receiving it and using it my soldering had never been the same, my soldering hobby had became more accurate and easier than my crappy soldering gun, thanks for sharing your videos

[familyplans]

i am so glad you did this video, cutting of the wires for the broken chargers is so obvious but it never even occurred to me to do it !!

[ebg]

You are very gifted at relaying information in an easy to understand way! I'm happy I found your channel. Great video's all around :)

Just discovered your channel and thanks for sharing this helpful video and information.
Earlier today I ordered a Longwei 3010KDS from Amazon Prime with 2 days delivery. I appreciate your help in providing reviews on these items. I am in the process of building my Electronics home workshop for Amateur Radio and Model Railroading & model drones.
I subscribed to your YouTube channel as well.

When charging LIPO batteries to 4.2v per cell you really need to put something to balance it on the balance wire leads. Even if that doesn’t talk to the power supply it will reduce the chance of over charging one cell and having it burst into flames.

The more you go over 1C in charging and discharging the battery the more important this is.

[stankotomasic]

this js really awesome. I find your lectures amazingly great, it helps me discover things i never knew they were possible.

[valdasmusvicas]

Well done! I'm sure you are helping to many people like me that is getting into electronics. Always helpful

[FPChris]

5:50 Glad you pointed this out. I have this model and was struggling with having to to set the current like that too.

[joziphstu]

You’re an awesome teacher, I really do appreciate your time

[OliverWoodphotography]

I've been after one of these for a while. I tend to use salvaged PC PSUs for my 12 & 5V needs. The info about battery charging was very useful.

[roncooke]

Great video you will a Professor one day if not already, very interesting i work on electric bikes, I to chop leads off battery chargers. I throw very little in the bin. If i was 30 years younger i would be your apprentice free for 12 months. Do keep the videos coming thank you Ron

[Portergetmybag]

Everyone always assumes I know the most basic things in their beginner video. I had no idea i could set the amp by shorting out!!! You made my day.
