$0.79 LM358 Breathing Lamp Electronics DIY Kit – Assembly and Review

In this video I’ll be assembling and reviewing the LM358-based soldering kit form Aliexpress/ebay.
It uses the double opamp to generate a square wave that feeds a transistor which in turn powers LEDs.

The one I bought can be found here:

It’s absolutely incredible that we can just buy a kit that contains a micro controller off the internet for less than a dollar. What a time to be alive.

Why you all keep on saying that the circuit is pretty useless? If you’re into pc modding or want to add some special light effects to your project, this kit is what you’re looking for…

Hey man – great video quality. I only recently got into circuits – a new 2017 hobby I guess. Hope to see a lot more from you!
