Hey Guys,

Great job so far.  I'm interested in how to apply power from a dc-dc converter - I disconnect the voltage regulator chip on the BE then what?  I'm assuming that I take the 2 usb data lines and connect that to a usb hub, and connect the + and - fromt he dc-dc to the BE.  

Where exactly do I plug those in?  Does anyone know?


Are my assumptions right?  I'm thinking that if I connect the 6+amps (for 24mhz) from the dc-dc converter to the BE with the + and - power going through the usb hub it will fry everything?

Also, the cheap dc-dc converters only do 3amps.  So if I connect one of them im parallel to the output of the voltage converter chip on the BE, will that work at doubling the amps?  Assuming the chip on BE does 3amps, my cheap dc-dc does 3 amps - together = 6 amps?  Or should I just disconnect the voltage converter chip on the BE and then connect in parallel 2 units of dc-dc 3 amps for 6 amps total?  Setting them to the same voltage though of course.

Any thoughts?


The problems are: I'm trying to overclock 10 usb block erupters.  If nobody can get 3 working together at 26mhz, then how will I connect those 10 at 24mhz?  Should I just give up?  haha  

If I connect a 20amp 5volt power supply to the BEs will that cause any problems?  Will that fry my usb 2.0 10 port hub? Will it fry my computer?  I just bought a bunch of stuff and am waiting for stuff to arrive so I can't test anything right now.  But can anyone who knows electronics help me?

I see someone mentioned a replacement voltage regulator that can handle 5amps but after looking at the datasheet im wondering that the pinouts are different, placing a metal plate on the bottom to contact the lx pads to the inductor seems ok but what about the heat dissipation?

What I'm really asking is, if you had like 100 usb block erupters (I dont have 100 haha but I wish) and you wanted to overclock all of them to 26mhz (or 24mhz, or even just 20mhz) how would u handle the power supply?  (not to mention the cooling)



Seems like the more I want to overclock the cheaper it is to just buy more units haha.

Also, anyone had any success connecting 10 units on a cheapo 10 port usb 2.0 hub?  With an external 5v power supply that can handle the amps? (cause the units on ebay come with a 1amp supply, I guess u could substitute it for a 5v 5amp power supply eh?)

Thanks!

you can mine the coins that are SHA-256 - there are several of them, ppc, terracoin, etc.
