RE: An Operational Amplifier is a fun DIY electronic building block everyone can use!
howdy @smithlabs! no comments here. from me either.
everyone likes it they just don't understand it!
I have no idea what this is lol!
Ouch, thought I made it easier to read! This is a part that lets you control signal levels by making them what ever is easy to monitor. Instead of reading tiny levels, you can make them larger, in a controlled way, so they still reflect input changes.
It just lets you push signals around until they behave.
:)
ok I didn't know you could push them around!
well probably more people than me understood your post. hopefully.
Yes, pushing signals around is the electronic equivalent, of a leash. With this you can control widely varied things, easily and inexpensively.
If you just figure out how to use the three lead opamp, you never need to go deeper inside, to have 50 years of engineering working for you on a home made DIY project.
The first differential amp I bought, cost me $70. The first IC opamp was $14, and I had to wait six weeks to get it. That same IC is nine cents today. Electronics can deliver lab grade opamps to the DIY tinkerer for pennies; that will give professional results, with easy building modules.
Don't you love new toys?
:)it's remarkable @smithlabs!
makes you wonder what things will be like in 5 or 10 years!
Well, I don't think handhelds will get too much smaller. Not because that is hard, but because people will begin loosing them too easy. The computing power will increase, a lot, and the displays will be projected, possibly onto glasses. the computers will recognize the movement of your eyes, and you will no longer need a mouse. The keyboard will become projected with an optical scanner for your fingers. Voice recognition will be the primary input method soon.
:)whaaattt??? what the?
what if I like the method like it is now?
did you ever tell me how long it will take those super batteries to come online? that's gonna be amazing.
All this tech is functional today, it is just too expensive, for now. The only constant in tech, is everything changes. I had a friend tell me that CPM (command Program for Microprocessors) was perfect, and we should never change it. Then came DOS, then Unix, then Windows; and somewhere in there a new fangled toy called a mouse snuck in....
:)The original post on the graphene batteries was an Amazon ad; they are for sale Now. Like all new tech, they are insanely high, but you can buy them today.
YES!
