This is a great video!

You also may use a heater which may easily dissipate 2-6 kW and also heat utility water. Besides of being dead cheap.

Thank you ! Great explanation !

You could use many small resistors in parallel.

blasphemie

Help us to bulid the project with different concept will you?

Plastic is not a megaohm conductor. Not even gigaohm. Please try again.

Can you share the PCB altium shematic and components you used, I want to use it in my project.

You made my arduino journey thank you ❤

A clothes washing machine with direct drive is typically free and over 3x the size of those motors

Another idea is to find an amateur potter and get them to make some tubes and fire them for you.

I had a wind turbine and its resistor was a thick wire about 5mm thick. And to stop the turbine when working on it the resistance was a solid bar of aluminum shorted across the terminals

I made a pair of heated gloves from ni-cr wire. It worked well but only had on off switch so was some times getting hot.

Hello try laser cut steel from jlpcb make a nece add and a good variable resistor

Cuando haras un welder inverter?

Do some larger wind turbines have mechanical brakes to prevent over spinning? It seems like this could be an alternative way of slowing the turbine shaft in a fully charged/high wind condition.

Please Electronob wich is the software that you used for animations ? thanks

Dump the energy to a water heater as a resistor

That was painful to watch... First of all that insulating tape will burn to crisp when that 'resistor' gets any substantial amount of power. You could have used lightbulbs, water heater elements, just dunked that wire into a bucket of water, steel wire or tape.

Daigram plzzz

Careful, one guy who made this got poisoned.

Great video, I was thinking of the ac ripple and thinking that you could absorbe the energy at low voltage stages and put them in series, dump them in battery then charge them back in parallel. This will put the generator in a low rpm high torque draw That way it will not waste time generating high voltage to fill battery.

CAN YOU UPLOAD AN BOM LIST PLEASE FOR PCB WAY ,THANKS

Thank you!! It seems like i found another information vid for my electrical projects i make! As its mu hobby!

How do I debug ESP32 in Arduino IDE ? I don't want use PlatformIO because it is mysterious define configuration code.

The design looks awesome for a size like this but you should consider going for a 4L pcb and remove those extra traces that are running underneath the rotary switch's moving area I can see how problematic it could be if those pogo pins start to wear the soldermask on those pins and short them in the long run.

you need kapton tape

You could also submerge the entire thing in a big bucket of distilled water but use ceramic, glass or stainless. For ceramic solutions you could pick up unwanted pottery such as floor vases or larg glass piece from your local 2nd hand store.

the graph nicely shows things... jacobs law. and the plateau or limitation of permanent magnets, fixed flux densities... it shows what is available in the LOAD, and only the load. it doesnt show how much power was applied to SPIN the generator. that requires a pivoting mount, torsion arm, and a load cell calibrated to show torque over time... the winding resistance should be close to 40R as well, the peak point on each curve. the same current in the load is flowing in the generator windings. producing heat. as the load resistance drops below the winding resistance, it is the GENERATOR that heats up. short it out. wheres the heat dissipated? solely in the windings. you will find when the load is that perfect "equal resistance" that half the APPLIED power to spin the generator will be available to the load, the other half? its being lost in the generator! as you get higher and higher resistance in the load, less current, you get proportionally more of the power applied appearing as heat in the load, and far less as heat in the generator. but less power is flowing through the COMPLETE circuit. example. a 10KW generator delivering 10KW, full power, requires 20KW to drive it. half the power is in the load, half in the generator. whereas the 10KW generator driving a 1kw load, only needs 1.1KW to drive it... only 1/10th of the power is lost in the generator winding resistance. there is an ideal value for full power, or maximum efficiency. 50/50. half the power in the load, half the power in the generator. there is a specific resistance for the optimum power transfer to the load. and then you get into batteries, and the fact that they arent resistors, need specific voltages to charge, and the current they draw is based on that voltage... it really does not suit the load requirements of a PM based wind turbine. more things to think about is how your rectifiers are interfering with the currents in each separate coil. that is, the BLDC is generally star wound, with no neutral connection, yet the rectifiers are generally wired delta... meaning that the current is shared between two phases that arent equal. you get conflicting EMFs, and losses... if you wire the rectifier so its connected to that neutral point, the efficiency increases dramatically as now each phase is "isolated" and can push its full power through the circuit connected (load) rather than fight a conflicting phase and only deliver the remainder.

Thanks!

Failure videos are sometimes the best to watch. And also - kudos for the time disclaimer for those who are after the information.

I'm going to attach a 3d printed lathe chuck to the overboard motor. The lathe chuck is printing right now

very good explain, Even if you apply oil on the PVC pipe, it comes off very easily thanks !

There is SOOOO much wrong with this video. PLEASE for the love of all man kind don't copy this!

bro its 128 not 127 becuase we use this formula "(X + Y)/2 = Halfway Between" to find it so its "(1 + 255)/2 = 128" so pls change it inthe code the reason i noticed while using aservo i saw a bit of dead zone in joys so this fixed To check that our answer is correct, we subtract 1 from 128 and subtract 128 from 255 and compare the two numbers: 128 - 1 = 127 255 - 128 = 127 As you can see, the halfway number is 127 higher than 1 and 127 lower than 255. Therefore, our halfway between answer of 128 above is correct.

can you up load the diagrams for voltage ,current ,frequency etc ? thanks

So do we call it reostate

"So - let's get started", followed by nearly three-quarters of a minute of not getting started, in a clip barely 12 minutes long. KZbin's advertising wastes enough time without embedding more in content. If I wanted to watch moneygrubbing I'd get a TV.

nice work, but can you please make the code to work with RC car controller(make the motor go both ways, forward and backwards)?

Electric hot water heater coils make fantastic high power resistors. They're around 8 to 10 ohms and can handle 3kw+. Super inexpensive too, around $20usd.

Winding resistor wire on glass can result in a hot wire cutting the glass.

How demonitise in 5 seconds :))

Thank you and appreciate your effort. Greetings to you from Turkey .

i thought the British were the champs of droning on and on about the same thing over and over. NOT SO. This guy give a new meaning to the word REDUNDANT. He put me to sleep, I woke up and he was still rambling about something. I pray I do not run across anymore of his vids.

I used to use incandescent light bulbs, needs lots of light bulb fittings but you can mix and match for the power you need. For low voltage I used car light bulbs. You can see when power is on. Sounds cheap but costs add up when you need a lot.

An other useful device for this type of testing is a carbon pile, the type used for testing automotive batteries and charging systems. As you turn the dial it compresses the carbon disks and the resistance decreases. Basically a high current low ohm variable resistor.

Keep going this was very interesting to understand MPPT cheers

Coil wire diameter?
