Title: i got so bored today im now rewiring my USB Hubs XD Post by: vm1990 on November 21, 2013, 02:35:05 PM ok so alot of people have Hubs that cant run the there full use so today i got really bored and started trying out a few suggestions
1 of the suggestions iv heard is to wire the Hub directly to the 5v lines on a PSU i dont like wiring at the best of times but i needed some hubs, so i went out and spent £10 on 2 Brand new Cheap Dlink hubs. having read on Amazon they come with 2amp plugs (turns out there 1 amp) instead of going through all sorts of crap and wasted time trying to return them i decided to have some fun and wire them to a PSU i wasnt going to spend alot of money on this so whipped out my test PSU an Alpine 500w around £15 new in the UK i then dug around my universal laptop chargers and to my surprise found out you can jam on into a female molex connector XD half a job now :D so now i created a female molex to female molex by cutting 2 molex to satas cut the sata ends off and joined them with a joint triped the powersupply to always be on and plugged the wires in and after a bit of tinkering and shouting it works perfectly :D im now going to wire a 2nd hub (same cheap model) wire the fans to it to cool all my stuff all in all its cost around £30 for 10 useable ports but from now until i reach 30A worth of devices it will only cost £1 per device not to mention all the electric saved due to less plugs around the room :D Title: Re: i got so bored today im now rewiring my USB Hubs XD Post by: vm1990 on November 21, 2013, 02:39:02 PM some pics for your plessure :D

Title: Re: i got so bored today im now rewiring my USB Hubs XD Post by: vm1990 on November 21, 2013, 03:54:41 PM well just finished the 2nd hub XD this is so much easier than using plugs.... :D
images to follow i might even start selling these :D if theres enough demand ill make a mk2 and do it all proper with crimpers and such. ***edit*** also still no smoke, fire or strange smells so must have done something right ;) red to red black to black :D https://i.imgur.com/CwAK9PD.jpg the universal adapter is perfect for the moles connection https://i.imgur.com/Pb8dumZ.jpg https://i.imgur.com/aCbuwMr.jpg the final product https://i.imgur.com/olUfq2E.jpg all are mining rock solid even less HW errors than if i used the dlink dhub7 (the more expensive version of these) Title: Re: i got so bored today im now rewiring my USB Hubs XD Post by: klondike_bar on November 21, 2013, 07:48:18 PM i tried this myself with the same hubs, but could only support 4 miners. adding a 5th created errors and knocked 1 or 2 out of action, not sure why (backfeed to/from the usb cord maybe?)
Title: Re: i got so bored today im now rewiring my USB Hubs XD Post by: vm1990 on November 21, 2013, 10:29:51 PM i did have problems with 1 of the hubs dropping all the 5 miners but managed to sort it by daisy chainging all the hubs through 1. i thinks it is the feedback from the USB to the PC that causes the problems but got it working and stable in the end thats 15 Erupters and 2 BFL 5GHs miners on 1 computer connected to 3 pools .
