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
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
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
the pool provides the clustering, a Pi cluster uses it's own solution, that's all I was saying albeit not very clearly.
Thanks for the links, does look like a great cost effective solution, but I'm not a licensed electrician and the items + shipping amount to more than buying individual PSU (~US$5 ea) so for me it's best to stick with the latter, however pedestrian, and potentially suffer downtime only for Pi that are affected by any single PSU failure. I'd still need to get more Pi's anyway, and they're much more than the PSU's (~US$38 ea).
And your uptime is awesome, GG
My Pi's have only been up a few months but haven't missed a beat, excepting reboots at the start for testing & mod.
unfortunately the information for bruva is going to be overwhelming
I was sharing my experiences & choices for you, bruva
lucky i got these devices from students failed attempts to hack the school network over the course of two years
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
Those silly pesky darn kids
your good luck though, as you said. The crypto course is a great idea! There may be questions about the capital investment and custody of crypto assets produced and tax etc, be prepared for that discussion.
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
Cool, thanks for sharing. Yes removing the GUI has a decent impact on the amount of code running & thus CPU load, wasn't sure if you were going to go for that, but I'm glad you did because it also reduces potential attack surface on the OS, less binaries, less exploits. Same for radio comms, turn off if not needed, more potential attack points removed. Taken together, less power usage, moreso than I'd expected.
Did you try the stats script I shared? To be honest, with 13 Pi's you'd be better off using a monitoring tool like Zabbix to collect & view data about temps & loads etc. There exists support & templates for Raspberry Pi, some links for you:
