Title: Can the BFL ASIC miners run off a laptop since they are powered by USB? Post by: w1seguy on May 09, 2013, 12:19:00 AM Will there be any disadvantages by doing so? This question is mainly directed to the 4.5 GH/s jalapeno miner.
Theeeeeenks! ::) Title: Re: Can the BFL ASIC miners run off a laptop since they are powered by USB? Post by: dman99 on May 09, 2013, 01:26:08 AM I'm pretty sure they found their ASICS to consume more power than originally thought, so now it comes with it's own 12v power supply. So, no need to worry about this anymore.

Post by: w1seguy on May 09, 2013, 02:44:36 AM Oh yes, I think you are right... the form factor is going to be bigger than they originally thought. Maybe this will make it less demanding on the computer so you can run programs while mining, instead of the GPU and strict mining setup.

This question is mainly directed to the 4.5 GH/s jalapeno miner. Theeeeeenks! ::) You need an external power source to run the current 5GH/s model. According to this video http://codinginmysleep.com/bfl-jalapeno-unboxing-and-demo/ they need ~30W. There are currently 2 USB powered mining devices that I know of. ASICMINER Block Erupter USB (https://bitcointalk.org/index.php?topic=195004.0) and Avalon Asic chip Mini USB miner (https://bitcointalk.org/index.php?topic=196281.msg2040708#msg2040708). The ASICMINER USB is currently in production, while the Avalon USB is still in design. Check out the Custom hardware forum (https://bitcointalk.org/index.php?board=76.0) to join group buys to purchase units. You should always read all the terms of the group buy before committing to an order. Happy mining, QG Title: Re: Can the BFL ASIC miners run off a laptop since they are powered by USB?

I like the idea of a purely USB powered miner and it's too bad BLF couldn't make it work. 5W to 30W is a big jump, but it still mines 4.5GH/s-5GH/s, and won't cut too much into profit.

Post by: BitshireHashaway on May 13, 2013, 04:26:49 PM Originally it probably could however now the power requirements have increased and as a result it comes with its own power supply so as a result that is no longer possible to do anymore.
