The projects my brothers and I are working on
op amp from discrete transistors plays music and controls DC motor
I made an op amp from discrete bjt transistors and use it to play music from a speaker and also control the direction and speed of a DC motor #circuitcomponents #opamp #transistor #amplifier #circuit #electronics #electronicsengineering

AC Dump Load Controller For Off Grid Solar
Get on a track. I want to see you jump it.
Someone may die.
Nice Video! What software do you use for simulating the circuit?
Falstad
@MakerBrothers Thanks!
Nice circuit! Funny how it ends up basically being made out of 4 current mirrors. What about the open loop gain? It is probably not that high considering the current mirrors don't provide much gain, right? I will have to try this out.
The open loop gain with no load on the output is very high, but as you load the output, the gain gets lower, since the op-amp outputs current. That's why I added the buffer stage, to boost the gain. Then I realized I was amplifying radio waves by accident, so I put the capacitor on the op amps output to lower the bandwidth, since the voltage of the capacitor driven by a current takes time to rise or fall
Another way to look at it is, for the output, the top transistor sources current and the bottom transistor sinks current. If the top transistor sources even a very small amount of current more or less than the bottom transistor sinks, the output voltage will swing to near the rail.
@@MakerBrothers Yes, your explanation makes perfect sense. So the follower buffer stage is exactly the right thing to improve the current gain, considering that the voltage gain is already quite high. I love tinkering with these discrete circuits :)

could you please list the parts the load sensor at least. thanks in advance!

Must be really cold, the camera man is shaking like a leaf!
shi insane frs
VERY interesting. Thanks !
Cool!,Who needs an Arduino, lol.
or a 555 timer.
Nice one! I'm currently just getting started in learning about components and stuff
600 would've been a better medium in my opinion..but still kick ass
The Exhaust gets bigger when it's happy😂😂
Awesome job!
Nice. Maybe a little Fatbob 4 gal. tank would fit? Great Job.
I really need to get my track planned and equipment rented.
Looks like a great time. I need to get myself a bike
Awesome!
Dang! And I thought turning a 150 into a 300 was cool lol.
Sick dude, now put supermoto wheels on it
I have a set you can throw on
80-90 in first gear is insane, especially on a dirtbike frame
mph or kph...?
BROTHUURRR moment, love the build
Cool, now put a gopro on the helmet and go real fast.
900cc 650hp turbo Rotex and some sand paddles👍 Lets go golfing in California 😂😂😂
Send her on a track
@@veeru0999 will do
thats so sick dudes congrats on the build cant wait to see it rip when you guys get it all sorted out
@@nopexd6137 the chain is rubbing on the exhaust pipe and the turn signals need to be mounted. After we get that fixed, we'll do a video of a ride around Milwaukee.
Insane lol gonna have update brakes if your actually gonna do some serious riding
what the basic machine you used??

You guys are insane, would love to see more content
how on earth did you build that at home insane bike
Mad lads
The exhaust slowly getting pushed out more and more
We didn't clamp it on yet
@@MakerBrothers yea it’s funny tho lmao
This doesn't look like easy DIY project. You have to know what are you doing.
Would not want your set up here in East Texas. LMAO....
Thank U , this is a good educational post, I subscribed Cheers !
Interesting, but the AC is off battery, not solar. Solar is charging the battery bank. Still learned something though, thanks.
Very interesting, have a couple systems running my sheds, don't have enough solar to run an AC that long. New sub to help your channel.
Thank you for posting this with instructions, now I am able to 100% cookie clicker.
Where can I get this it isn’t on Amazon anymore. What a great product.
@@basadial1 I just sent more to the warehouse. They should be available sometime this week.
Once those lead acid batteries wear out, be sure and replace them with LiFePO4 batteries because they are (dollar per watt-hour) a much better value; last longer, weigh less and trouble free.
hey, just thought id leave a comment as I recently started getting into micro controllers. Great vid man 😁
opportunity load controller very interesting ! ! ! Thanks!
what kind of circuit is it? buck , boost ect?
@@Corybobory-vm9kl boost power factor correction. I'll explain it more in detail when I finish the final version
hey man, please don't test across your chest. use one hand if you can to test.
That's awesome! high voltage DC is the way to go.
For all those commenting to move the panels, its likely the case that anywhere else is more shaded. You can only do what you can with the property orientation and plant coverage you have!! Why dont people consider this before doling out their school marm advice and highly unwarranted criticism?!
What does a system like yours costs?
@@StarwaterCWS somewhere around 1500 us dollars using new panels and equipment
@@MakerBrothers thanks!
whats the total cost for setup like that
@@supjay3945 around 1500 us dollars for new panels and equipment
I have a similar setup for my AC. Only wish I had gone 48v so will switch it when inverter needs replacing. My next step I'll get a window unit with a high seer rating. They cost a little more. But you can get around 10k BTU @ 350 watts if you get a really good one (Midea on Amazon makes some good ones). A cheap way to seal those gaps around your window AC is take walmart bag. Wad them up, and stuff them in the gaps with a screwdriver or butter knife. Works real well sealing the window, and everyone has leftover bags. :)
Better to tape the gaps, and cut XPS foam to fit into there. Regular grocery bags made out of LDPE are not insulating much at all, as the material itself is fairly thermally conductive. If you put loose fiber fill or the like in them, that would help a lot.
Ceer instead of Seer on that lable LOL... yeah gotta love those off brand chinese crap... as for you choice of panel placement and setup LOL. .no comment
kool beans!
