POWER TO THE USB HUB (noob hobby style)
 
 I had problems with this type of adapter in that it burnt out killing the usb hub (nasty smell) or it could
 not supply the power needed for more than 2 red 5gh red bifurys on a 10 port usb hub.

 

 So more power was needed and this is my solution to the problem.
 After reading many blogs and watching youtube posts which were all helpful i did this.
 Thanks to all.

 I got a 680w pc power unit to MOD.

 
 
 I then soldered the green wire to one of the black wires this switches it on.
 Secondly very important is to solder a 12v - 10w - 22ohm coil resister to a yellow 12v and black N wire.
 It thinks its running a motherboard or it will make a high pitch whine and dies.
 This leaves a bunch of black Neutral, red 5v yellow, 12v & orange 3.5v wires free.
 Cap off any redudant wires i.e purple & gray

 (Dont forget to insulate all bare wires)

 

 Then i striped the ends of the individal wires and soldered the wires to make single ends
 and fitted them into a large terminal block I had hot glued to the side of the power pack.
 Black Neutral, red 5v, yellow 12v & orange 3.5v and a spare N bridged from the main N
 terminal to an end terminal just in case its needed for the 3.5v.

 

 

 Then i Bridged terminal 3 blocks 12v yellow, 5v red, black Nutral and fixed them to a board to
 give more power outputs so i can add more usb hubs when needed

 

 The next thing i did was bridge the fuse on a 4 port 5v powered usb hub at the moment
 has its own power adapter  but will be powered from the terminal.

 

 Blue 10 port usb hub. this hub is the one to chose for the job.

 Needing to get a good flow of power to the bifurys was next.
 I directly soldered onto the power points on the blue 10 port hub and bridged the 5v points to each
 port & bridged the trip fuse.

 

 

 I am running minepeon on a raspberry pi so i also added heat sink to the cpu by sawing an old
 pc heat sink to the right size and fixing with heat sink compound.
 The raspberry pi has its own power adapter.

 

 

 Fans are needed as bifurys get hot,There are two fans for the bifurys, they have their own power supply
 (an old 12v adapter for scanner) at the moment but will be powered from the power unit when i get a fan controler.
 One is for cooling the pi and the other two are for the Bifurys.
 Plus there are three usb cables with the red wire snipped so there is no power passing through them.
 An ethernet cable if you dont use wifi.

 

 8 red bifurys 5 ghs each 40gh total they dont all flash but they do hash.
 i have zadiged them and tweezered to update firmware.

 I have a few errors i am trying to fix.
 I have probably missed something being a bit of a noob, but its giving me the 40 gh that i wanted.

 I hope this is helpful in solving the power problem with multi port usb hubs and their adapters
 for powering ASIC block eruters .

or you could try this rpi and bi-fury 5ghs 1 block to start.

a diy cool box to keep it about 40 c.

NOT AN AD

just a nooby doing his thing lol got to start some where.

this is my first miner hope to make it bigger soon.

best regards Dave
 

my noobs work!!

Hi just started mining with brand new red Bi-Fury 5ghs
with raspberry pi - minepeon
change cgminer to bfgminer just plug it in & change its
pool address using minepeon ssh screen
([p]ool management) put your url: > username: > & delete the
default, sudo reboot & off it goes

5.12 ghs $1.40 in 3 days. Make sure you use a good fan or

2 works fine at 40 °c . 1 today 5 more on there way

thanks to cryptostore.io great price.

Hope I don't sound to much like a noob but I cant get minepeon to let me in
access denied have set up raspberry pi more than once and after working day & night
I had everything setup booted the raspberry with 5gh bi-fury and it wont work.

help would be greatly appreciated.
