Nearly two months after version 3.18, the developers around Robert Piotrowski (revoxhere) have finished the Duinocoin miner version 3.2.

Version 3.2 of the Duinocoin software brings some small fixes. On the Raspberry Pi, the LED now flashes on demand to indicate successful mining. At the first start the miner software checks from version 3.2 if wallet and minig key are correct.

It's easy: Getting started with Duinocoin (DUCO) using an Arduino UNO/Nano

Translations: DE, SV

The Duinocoin (DUCO) was originally developed for the Arduino UNO. Therefore, mining with the Arduino UNO is the ideal introduction to DUCO mining with microcontrollers..

In addition to an Arduino UNO or Nano, a PC, a notebook or a Raspberry Pi (for the Arduino development environment (IDE) and as a communication computer) is sufficient to get started with DUCO mining.

Round three and a half months after the major release 3.0, Robert Piotrowski (revoxhere) and his development team have completed version 3.18 of the Duinocoin miner.

Version 3.18 of the Duinocoin software is said to increase the hashrate on ESP8266 boards by up to 10%. An ESP32 memory leak was fixed, plus there are many small improvements like the possibility to switch off flashing LEDs.

What to do if you can't get access to the serial port/USB under GNU/Linux?

Translations: DE, SV

If the access rights to device files (serial ports, USB) are not set appropriately under GNU/Linux, the user can neither program a microcontroller nor use the mining software 'AVR_Miner.py'.

If you want to program an Arduino UNO with the Arduino IDE for the first time, you will almost always run into the problem under GNU/Linux that the IDE does not have access to the serial port (i.e. USB) and thus cannot find the microcontroller. The solution: Correct group membership (and not release device files for all/everyone as often described!).

How to set up the Arduino IDE and update all libraries

The default settings of the Arduino IDE are not optimal and do not adhere to system defaults under GNU/Linux, for example. A few adjustments make it easier to work with the development environment.

The Arduino IDE is quickly installed and can be used even better in "portable mode". Before you start, however, some settings should be optimised.

There are many advantages to installing the Arduino IDE in "portable mode". This logically separates the actual IDE from the personal settings, libraries and core architecture.

A normal Arduino IDE installation quickly overflows with additionally installed libraries, board definitions and other things. You can hardly find your way around in this chaos. A small trick ensures that the actual development environment and data for your own projects are cleanly separated from each other.

Those who want to mine the Duinocoin (DUCO) need software to program an Arduino UNO/Nano or an ESP8266/ESP32. The easiest way to do this is to use the free and open source Arduino IDE.

The easiest way to program mining software on a microcontroller is to use the Arduino IDE (development environment). The free and open source software is offered by the Arduino Project as a free download for Windows, GNU/Linux and Mac OS X.

What to do if miners can't contact the Duinocoin server?

Translations: DE, SV

If the Duinocoin network is under (too) heavy load or if a comedian has started another DDoS attack, the miners will time out when trying to connect. There is a solution.

Sometimes the pool servers - for whatever reason - do not respond to requests from the miners. On the one hand, this is annoying because at that moment your own miners cannot generate a DUCO. On the other hand, it can also cost a lot of time when troubleshooting your own mining rig, because it is not always clear at first whether the error lies in the software for the rig or with the servers.

Duinocoin version 3.0 released

Duinocoin version 3.0 released

The new version brings higher hash performance to Arduino & Co

Translations: DE, SV

The development team around Duinocoin inventor Robert Piotrowski (revoxhere) has released version 3.0 of the cryptocurrency tailored for microcontrollers.

Version 3.0 of the Duinocoin software brings more speed to the Arduino Uno, the ESP8266/ESP32 boards and other microcontrollers and thus higher hash rates for mining. There is a fancy, web-based dashboard for the ESP8266/ESP32 and the PC miner manages up to ten times the hash rate thanks to "fasthash".
