I'm thinking the arduino, ftdi and the bluetooth module could be replaced with a ESP32. Same code for the most part. Smaller footprint. USB chargeable.

to prevent singing and increase motor life, increase the frequency to 31k instead of 490hz. TCCR2B = TCCR2B & B11111000 | B00000001; // for PWM frequency of 31372.55 Hz on D3 and D11

only if your power generation produces carbon.

fartilizer for plants, or if using spiruline, food for you.

34 of these would counter one person's co2 exhalation.

I was curious if I could practically cleanse the air in a sealed habitation. 1 person releases approximately 1000 grams of CO2 daily. One 2 liter bottle of algae can remove 30 grams of CO2 daily, so I figure 34 bottles per person. Algae grow great using human pee as the medium, so no need to purchase "nutrients".

It's not a sketchup up file. rename the tmp files to the listed file names above, and open with ExpressPCB.

150 amp 3 phase diode bridge. consists of 6 150 amp diodes. A 150a current shunt with an arduino reported power produced.

Each phase is not delivering the exact current at the same time. You add the current of the 3 phases, and then divide by three to get the average current. (14.1a + 13.8a + 13.9a) / 3 = 13.9a average. or in the above turbine each phase is still handling close to 83 amps, not 27.

1" x 2" x 1/2", alternating north side up, south side up, and the mating rotor is the opposite. north to south side facing each other.

Thank you for those links. I never got back to this project, and don't have any plans on doing so in the near future.

That is correct. That is the basis for this design.

We are charging a battery bank that feeds an inverter. We didn't have a mains to connect to.

Yes the ends were sanded and soldered to the down cables going to the diode bridge in the battery room.

Requires multiple coils in series and fast moving magnets.

I do not understand the purpose of D1 / D2. I used a 74HC14 with no issues, .1uf cap, and 10k resistors.

VCC - USBThat's 5v. Of course, a 5v display won't work on 3.3v.

so, you are using electricity, to create steam, to run an alternator to create electricity. Seems a waste of the original electric you started with. What is the purpose? Science project?

here is one possible source - https://www.kjmagnetics.com/You can google neodymium magnets and find many sources.

They alternate. one magnet is S up (away from coil), N down (towards coil), the next is N up, S down. It's mating magnet on the other plate is the reverse, S to the N of the magnet on the other side.

.ino files would be more helpful than hex files, then we can understand how it's working.

How would I mod this for 120v / 60 hz? Not understanding the relationship between ms and hz.

I can. Contact me at greentrust@gmail.com

instructables butchers the include commands. can you list the code on pastebin and link to it?

1/4" to 1/2" works fine. I got them built at a local metal shop.

Absolutely. This works with any battery storage system.

Easily. Use a shunt, and you can monitor hundreds of amps. Search my arduinotronics blog for the word shunt

You should still have a resistor on the LED to protect the pins on the ESP8266. LED Resistors are for current limiting, not voltage dropping per se

Excellent. Thank you!
