so anybody on here has experience mining magi with raspberry pi??? looking to find out if there any new updated cpuminer for them....
I use 2x RPi2B+ 32-bit (earlier BCM not later), set up thus: - raspbian-stretch-lite-2019-04-08 although this is now replaced by Buster
- cli only, X11 & all extraneous packages removed including WiFi & Bt (CAT6 conx only)
- cheap 4GB SD card
- m-cpuminer-v2
- managed via SSH
The pair achieve about 10-15KH/s, wish I had more but RPi3B+ & PSU cost around $55-60 each where I currently live, so making a cluster becomes as expensive as a small x86 64-bit desktop system. Here's a link to NovaSpirit's guide to setting up a magi miner on RPi3, he uses wolf-m7m-cpuminer ( https://github.com/novaspirit/wolf-m7m-cpuminer) which I have used successfully on old spare dual-Xeon servers running Linux Mint (while I still had access to them). Both miners are about the same vintage, I don't know if there's any significant difference: https://www.novaspirit.com/2017/10/19/crypto-mining-sbc/I really wish there was more active development on XMG/Magi, I still like this coin and the idea of it, maybe some day a developer will pick it up as a project to champion but that sounds too much like singing "Some day my prince will come"  You can try to find alternatives. I had raspberry 2, now sometimes while watching movies mining with orange pi pc, it is achieving ~3.7 kh/s. You wanna cluster? Take a look into orange pi https://www.aliexpress.com/item/32848891030.html?spm=2114.12010608.0.0.a43c395ckpqORW it is ~25$ with shipping, and H6 is a 64 bit modern cpu. You don't need +PSU for every board. Just get simple PC ATX PSU, which you can get very cheap everywhere. They have +12V and +5V. One PSU is more than enough for cluster of 4, so you can make 16 core system. https://www.youtube.com/watch?v=jgFh6yLe6Os |

Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

having trouble changing my gui setting from mXMG to XMG in the wallet. tried everything in settings on the GUI and it won't keep it at XMG... any suggestions?
You may've found this already, but it's located here: Settings > Options > Display tab > Unit to show amounts in: (XMG | mXMG | μXMG) |

i have mine setup with https://github.com/jeezz/piminer-m7 gives you the governor option so you can select performance, overclock and other features to bump up you hashrate. for me i have currently 2 pi 3b v1.3 and i get 15-18Kh/s and its not much of a bump up but it does help. piminer is a shell script that you call from BASH to automate handling of the whole miner setup process (someone worked out the RPi3 dependencies & compile flags for you); all of which is pretty neat. You can see it here: https://github.com/jeezz/piminer-m7/blob/master/piminer-install.shI wrote a shell script to check temps/OS-version/filesystem via SSH, ie: displayed on cmd line. If I weren't so lazy stupid busy I'd set cron to check temps & email alert if temp => X°. It's shown below if you want it, for convenience I'd create it where you land in SSH/terminal on desktop, but if you have desktop environment look into conky, especially conky colors: # create temps/stat script
nano stat.sh
# paste the following, exit & save
/opt/vc/bin/vcgencmd measure_temp
uname -a
df -h
# make executable
chmod +x stat.sh More on vcgencmd: https://elinux.org/RPI_vcgencmd_usageso far i am looking into making a cluster on amazon i found a stacker for 4 pi and they come with fan and heat sinks, neat thing is the fans are above the CPU so it keeps it cool. the PSU you can go for a cheap 30A PSU (*$30) they use for 3D printers (i have a few sitting around) and pick up a USB adapter or a buck down converter (usually $8-10) to keep the 5v 3a needed per pi and setup a fan for added air flow to keep under 70C...... i know its a lot to do a pi cluster but if you live in the states i probably help send the PSU from my old 3D printer.
That's a very kind offer & demonstrates the disposition of the Magicoin community that attracted me here  - unfortunately I'm not stateside, which is why hardware is so expensive (US is a major shipping destination for Asian mfr & bulk runs save $, everywhere is more or less 'other' destination lol). 1 PSU & adapters/converters per RPi vs individual PSU: comparison not just of cost but also failure domain, 1 PSU is a single point of failure whereas separate PSU spreads that domain. Choices... constraints... I would like to make a 'cluster' too, strictly speaking it isn't a cluster unless using some quorum/replication solution like Galera for MariaDB. I know the stackers you mentioned, they're the best solution for multi-pi pools - cheap, effective, active cooling. SOLD  https://www.ebay.com/itm/254051554116. I'm also considering using something like this, I was given one but only a few of the USB interfaces are 3A, and this one is only 2.4A per, so that's a limiting factor: https://www.ebay.com/itm/264125371811Note that active cooling is a must-have for pi-stack mining, unless you live in Barrow Alaska  - the combined heat output of many RPi in proximity... the pi4 is out that thing can pump out hash rates for monero coin like its a USB asic stick. =]
Wonder which binaries/dependencies it is able to run, there are some issues that need to be worked out, check YouTube vids for more info before diving in, just in case. i just don't see how some of these miners getting 3.7MH/s for cpu coins
Some pools don't enforce limits  so people will naturally go as hard as they can, which hurts all magi miners. If you have a pool of modern CPUs you can thrash out solved blocks of hashes like there's no tomorrow and cripple the payout. thank you for the information you have given me, i didn't think about removing the BT and the wifi to reduce power requirements. will do that to see if it helps keep it from hitting undervoltage every so often
Most welcome my friend; I'm unsure if removing software support for those chipsets will lower power requirements, I removed them because RPi 2B+ has no WiFi/Bt and it reduced space/boot a little bit. I run headless (cli only) so removing GUI (X11) yielded even moreso. If you want to do the same then run these cmds from bash, omit X* if using desktop (or it'll go bye-bye ): # RPi <3 that have no Bluetooth or WiFi dongle, remove pkg:
sudo apt-get remove --purge bluez
sudo apt-get remove --purge wpasupplicant
# Headless RPi that has no GUI, remove pkg:
sudo apt-get remove --purge libx11* Apologies for thread hijack, just tryin' ta help a bruva out. We now returning you to your regularly scheduled posts... |

Hey guys, I need some help  I was mining magi long long ago, then stopped and for a short spell in 2017 I had wallet running for staking. Life got hectic and had to switch everything off again.... fast forward to now... somehow I can't get my wallet up and going. Back in 2017 I asked advice about staking and I was told to have another address and move coins because my coins were too old. It worked but now for the life of me I can't remember how i was doing it. I even lost my old login in bitcointalk and had to open a new account. All up I have about 6000XMG  are my coins gone? Can anyone help me, I remember I moved coins back and forward a couple of times but now restoring the wallet I only have options to be in my second address. Heck I must be doing it wrong. Sorry I am stressed. Do I make any sense? |

I see 9Eqzf11G2GkGmGrbrQbdJXcCthE3zzotuv has around 15 coins left. This address 9PSNtrK2dnhy3BZXJqFDrvbwmWuzGsQavy has 6025 coins. I hope you have a wallet with the last address with 6025 coins, is this right? |

In Magi can I have more than one wallet within the same GUI? I mean because I know my encryption pass, do I have a way to get back to the one with 6025 coins. I am quite sure I didn't have to "swap" wallet.dat |

AKA sending coins to yourself to stake, which is the most common way to set up blocks in your wallet to make a good size stake. learning how to stake myself. so that you found the wallet address which is good. now did you use your wallet.dat file for the gui to check if it has multiple addresses?? i suggest downloading the most recent blockchain and sync up your wallet to see what you have as of now. |

Looks like back again, isn't? it was up and running the entire time but wasn't giving transactions. as of right now of this posting minerclaim is back at it not showing the blocks that it has mined and no rewards going out to the pool..... before we had them post that it's a backend error but i haven't seen the guy that is involved with minerclaim being on or active in a while and no way for me to contact him. yea i know i am on here too much recently but as of now school is out so why not be more active =] |

We now returning you to your regularly scheduled posts...nope we are not back to are regular scheduled posts....... yes a cluster is a grouping of multiple computers working on a same task divided up to process it faster and sure you can say other wise but sharing a same PSU isn't gonna have any issues if their is a failed PSU and the who thing goes down. if that happens than you lose out on mining until it's fixed but the cheapest route to do the stacker is having this: https://www.amazon.com/EAGWELL-Universal-Regulated-Switching-Computer/dp/B06XW76584/ref=sr_1_2?keywords=30+amp+3d+printer+psu&qid=1566388998&s=gateway&sr=8-2 plus this: https://www.amazon.com/MakerHawk-Voltage-Regulator-Supply-Charging/dp/B07KWRH61D/ref=sr_1_3?keywords=usb+3+amp+buck+up&qid=1566389198&s=gateway&sr=8-3to provide the full 3 amps to keep the pi running to prevent it from triggering under voltage and slowing down the cpu to not mine at peak performance. i haven't had any down time with my stacker/cluster in the 6 months of running. granted i am currently stacked at 13 pi 3b v1.3 which i am content with and keep adding as time goes on. unfortunately the information for bruva is going to be overwhelming and you're right with people going hard on mining trying to get the most out of what they can for coin is INSANE!!! sure i found out that you can pick up a server blade off amazon used for about $180-220 but the power requirements is two 750 watt PSU which would draw more power than what the coin is worth but is it really worth hashing with that much power for magi....... most definitely not....... as of right now with my rig im actually not gonna break even for another 2yrs if i put the $$ into it out of pocket, i am actually lucky i got these devices from students failed attempts to hack the school network over the course of two years, while they collecting dust i decided to use them and learn for myself about crypto..... might start a course in crypto and have student try to write some programs up to see if we can get this magi community bumping again who knows, `mike p.s.- meekness little info the disabling the BT, removing GUI and disabling the LED lights actually did help mining rig out power usage dropped 14.5% no with that times 13 i will make a profit monthly of 18 cents =] looks like i will make out after all |

Guys, thank you for helping about the wallet issue I am having. For the life of me I don't remember how I was sending coins around. I have 4 different wallet.dat which I backed up from 2016 but now I am worried to try anything. Can you tell me where I should look in the GUI? Also, as the blockchain is fully downloaded and wallet is syncronized, is it safe for me to shut wallet down and try the different wallet.dat? If so, where would I look to see if I get access to both my addresses? Bigstinker, you probably figured it out already but this is what I was doing for staking: # rpcuser and rpcpassword to secure the JSON-RPC api rpcuser=user rpcpassword=pass # Listen for RPC addnodeions on this TCP port: rpcport=8232 # accept JSON-RPC commands server=1 daemon=1 # accept connections from outside listen=0 rpcallowip=127.0.0.1 rpcthreads=1200 # Add nodes to addnode to specific peers # addnode=104.128.225.215 # addnode=216.189.151.56 # addnode=216.189.144.213 # addnode=103.11.64.40 # addnode=45.35.251.73 # addnode=104.131.42.100 # addnode=104.131.57.65 # addnode=162.245.217.165 # addnode=213.32.21.37 # Enable/Disable mPoS Stacking 1=Enable posii=1 # value greater than threshold is splitted stakesplitthreshold=500 # value lesser than threshold is splitted stakecombinethreshold=500 Hope it helps, I can't tell you if these IP are still valid hence I rem them all out. Last 3 params are the most important, enable pos with posii=1, any amount bigger than "threshold" (in my case 500) is used for staking and anything smaller than 500 is used to "combine". Basically once you reach 500, that amount is used for staking. |
