Man talk about cheap or cutting corners i had to open the controller mine came with the RPI b not b plus or 2b but mine was rusting and old the pins on the SD slot were bent to the point the only SD it worked with was the one it came with and that was hard to get it to boot or the only one that would boot the miner with any image i found so far that works on the A4 ... .. good fpr me thu i had a b i don't use any more with no bent pins on the SD slot, and no rust ... I put it on the addon board it booted up no waiting sad thu i'm gonna figure out or try to plug a RPI 3 or any PI into the board , the add on board on the RPI b is all you really need.
my other question is there any open Source Software for that version of CGMINer ? and i wish BFG worked with it , i know it doesn't ...
just got my first A4, thing is loud, something i wont be running at nite glad for me it's just hobby right now..
my question now has anyone come up with a quieter fan ?. All ready like it but the nosie gonna have to either find quieter fans or build something around it...
Not that I know of. The specs on the fan are 200CFM, so as long as you can vent 200CFM through the rig you should be able to replace with ducting or other forced air.
so im guessing it can be watered cooled if you want to go that route and have some heat sinks made, the boards from what i saw are your normal type hash boards not like the miners bitmian put out after the S5 ... I didn't open the miner and have no plans to till the warranty is up . only went by pictures i saw ...
No they still use the old Pis, they have to be the version 2 of the B . one of mine only has the BCM chip and ethernet controller, they left off everything else, no usb jack , power , etc, and yes all of mine are rusty. As as for making it work on a newer version, well it wont work out of the box, it will have to be recompiled due to the bcm2708 libraries needing to be different , not to say it cant be . I have been allowed to get the source code and were working on making them work a lot better myself and another person have made some good progress.
AS far as the fans , yes they are loud but I put some dc-dc converters on them dropped them to about 8volts and they are a lot more tolerable , it only changed the CFM about 30% and they run only about +5c higher.
I guess I can ask what would people like to see in this, things we have done so far is make them a lot more stable and done the xnsub addition.
While it would be neat to water cool them I'd say be more hassle than good, although I have though about it.
