How to mine Duino Coin / DUCO Cryptocurrency on I2C ESP NANO Rig

[@gerhardskronn6546]

This is wonderful. Thank you very much for sharing. (I've built my rig on a strip board though because I was too lazy for all the wire soldering. ;) This way its basically just one big bus for 5V, GND and I2C, connected to a Pi)

[@sabreman79]

Thanks so much for the video and the code. Just finished my own rig using Nanos and a wemos d1 mini pro that I had lying around. Now happily mining duino coin!

Hey bro, this was a really relaxing and well put together video, amazing job bro keep up the great work@

Brother, what an incredible video. Thank you very much... Is this model you used the Arduino Nano v3?

[@voltovsky3856]

Cool tutorial which is explaining all stuff about how to mine duinocoin

[@CrazyCoupleDIY]

You should have bought nano boards without pin headers on it and then just shouldered whatever you needed rather than cutting it all off. Anyways nice video

[@99Victor]

At 1:06 minutes on your video, what is the breakout board at the top center of your perfboard? Need a list of materials also called a bill of materials or B.O.M.; to include cost and where you bought/get them from. Oh your music is just right, not over bearing, or too loud; I can hear you clearly (thanks). And thanks for the little defense joke (ha ha ha). Okay; at 15:20 minutes you've removed the breakout board (itty bitty) that I was talking about ealier.

[@cutsdbz]

Great video, I have never done this crypto thing, but this looks like a nice exposure, I have like 5 spare D1-Minis lying around. Can I use one as master and the rest as slave? I use the D1-Mini for most of my projects because they are cheaper than the nano.

[@taranagnew436]

what pins (on nano's) do i have to desolder/bend? FYI my nano's came with pins attached

[@MultikPS]

What is the small module in the center? Linking esp and nano? The scheme and your soldering is different. There is no connection to the second white row in the diagram.

This looks amazing! That's exactly what I was looking for. But I don't want to use a 3,3V-Logic-Converter. So do you think it would work if I use like only 5 Arduino Nanos and power them separately with 3,3V? And how much Duco did you actually earn in the past few days? Thanks in advance

[@JKRolling]

yes. it can work without LLC at 3.3V. At lower voltage, the power source will need to be able to provide more current. There might be instability issue as Nanos is designed to run at 5V

I am building the i2c interface with an NodeMCU 8266 and 10 arduino nano, on the github page in the connection diagram I see D1 mini 8266 5V pin connected , but on the connection pinouts I dont see it ? do I need to connect the NodeMCU 5V (Vin I think?) ?

[@JKRolling]

seems like the nodemcu do not have 5V output pin, you may skip that wire. Add one external 5V source to the Nano. e.g you can connect USB to one of the Nano, since all Nano 5V and GND pin were connected, that should power all Nano up

[@denizsevinc9334]

@@JKRolling connecting the usb on nano stops the nodemcu :( can i use a esp32 with 5v pin ?

[@denizsevinc9334]

@@JKRolling so i modified the rig with nodemcu esp32 , now cant connect to server

[@JKRolling]

the addition of usb is to power the nano. nodemcu itself need a separate power (or you can use the power rail from nano if you know what you're doing). btw, the LLC still need to have the HV connected to 5v to the nano

[@JKRolling]

I do not have esp32 to see what went wrong. so use esp8266 for now Edit: just got my hands on esp32. debugged and fixed the code. anyone with esp32 should be able to load the i2c master design and start mining!

[@dhritimanroy2839]

Sir i want to know that why is the Hash Rate so low? I am running only one miner on ESP8266 and it is showing a hashrate of approx 9.29KH/s. but you have 10 nanos and the Hash Rate is only 1.9KH/s.. when nano is supposed to be more powerful at mining Duco than ESP8266.

[@JKRolling]

This is the uniqueness of duino-coin. AVR will earn more than esp because more hashrate is not equal to more earning. You may find more info from the white paper. github.com/revoxhere/duino-coin/blob/gh-pages/assets/whitepaper.pdf

nano requires individual sketch upload via usb. the nanos were powered by the wemos 5v pin. esp 3.3v might work with the nanos, you may skip the LLC too. but ymmv as nano is designed to operate at 5v

[@vanhetgoor]

Why, why, why! Why painstakingly remove some of the pins of the Arduino while little Chines girls have put those pins in with their tiny child-labour fingers? Simply buy an Arduino without the pins! It saves you and the viewers a lot of time. And if there would not be other Arduino's around, even then it would not by necessary to remove the pins you don't want to use. You can do this by not making a connection to them. For the working of the Arduino it does not matter that much if it is flat on his back or on its side. For the next project you might need the other pins of the Arduino and where would you find tiny Chinese child-labour fingers to put them back in again?

[@JKRolling]

You have a good point there. Depending where you live, you may or may not find the nano without pins. The pins in the video were removed so the rig can be more compact. Desoldering is just one of many ways. Some may just use a pin cutter to do the job.
