Thanks my friend, that was interesting, thanks for your input, regards jack..

Looking forward to seeing your PCB results.
Also I want to say thank you for your op amp tutorials. I think something 'clicked' after watching your tutorials and then doing some experiments. I now think that the primary difference between an amplifier and a Schmitt trigger is that the Schmitt trigger has a feedback resistor connected between the output and the non-inverting input whereas an amplifier has an output resistor connected between the output and the inverting input.

Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH)2. That might help
Another very good video, This set of videos have been nice and informative :-D

Great video. Small correction at 1:00: cations are positive, anions are negative.

Your great at explaining this stuff, are you a lecturer or just very knowledgeable in this feild. I can follow what your saying without even having to think about it. So you got a gift at explaining a stuff. I hope you keep up the good work, 👍 and love your channel!!. "SIMPLY PUT " your the I make colidel ( spelling that wrong) silver using electrolysis it very good for you. Any tips on the best current and voltage for making it???? I would epricate it a lot if you do know.. Thank you for the video. I loved it.👍😁

Keep anything you don't want etched out of the liquid...

I too learned this when anodizing some aluminium. Sadly the bits I was using to hold the aluminium in were eaten away very quickly. Pretty frustrating setting it up with something that wasn't just going to get completely eaten before the anodizing complete!

Permanent marker!!! So that's why printing your circuits on paper first before ya lay it onto copper plate PCB for etching works!! Cool. P.s. Are you a lecturer or teacher?? Or just a guy who has a love of learning??. Coz your knowledge and understanding of how things work is amazing...🤔👍 just love you stuff!!!!

Interesting. Now I understand how my Salt Water pool (1400ppm Salt), makes chlorine. A salt water pool has a device (I call it a zapper) that shocks the salt water with electricity to produce chlorine. Much better than constantly having to dump chlorine into the pool every 3 or 4 days. About every 18 months my zapper would burn out, then I discovered that my pool water had too much calcium (well water). So after removing the calcium by refilling the pool via a soft water system, my zapper did not burn out.
If I remember right, the zapper (The chlorine generator) which creates the chlorine via the electrical reaction, never depleted the salt in the pool, hence I never had to add salt to the pool. Somehow the process creates a balance?


Also, if you have never been in a salt-water swimming pool, they are bomb. The salt content in your tears (eyes), is around 1400 ppm, same as the pool water. The water feels slippery on your skin, no odor of chlorine because you can keep the chlorine level way down because you have a machine automating the generation. Pool service companies, that service non-salt-water pools just bomb the pool with massive amounts of chlorine (usually enough to last about 1 week). So the pool reeks of chlorine for the next 3 days. Awful.
