Scarab. Im trying to figure this out. I havr an extra psu for this but no extra comp to put it to. All the ones I have running have all their watts used by gpua. So I want the brick. Can I buy a generic brick that will work? Do the splitters come with the boards? And I wojld possibly be interested in a tower unit. But dont the pins they come with allow them to be stacked?
I'm not 100% sure, but the brass standoffs do not seem to come with the Lancelots, hence the idea of making a frame came to me.
http://www.cardreaderfactory.com/shop/bitcoin.htmlA generic brick with the right specs should power these. They sell 12v 10amp bricks on thier site and state that 1 brick powers 4 devices. They don't state if the brick has 4 output plugs though. If you view thier ATX splitter page, they give a bunch of options for buying wires with plugs. I am sure that getting the plugs is not an issue, you simply need the correct size (5.5/2.5mm power plug), and I am assuming that we will need to wire them ourselves. This is pretty easy soldering. Just get the polarity correct!
So, you buy any bricks with the right specs (input volts 120 for N. America, and 220 for Europe), probably have to cut off the existing 12v output plug, and solder on 4 of the correctly sized plugs in parallel to power 4 of the Lancelots.
Alternatively, you can use a computer ATX power supply (at 600 or more watts), but then you need to figure out how to adapt it to power up to 20 lancelots. This is where their ATX adapter breakout board comes in handy, which is why some of us asked for this. Their breakout board is a bit unusual in that it has 20 of the 12V outputs. You buy 20 of their wires + plugs and simply screw the bare wire ends into the green terminals. You then plug a 600 watt ATX power supply (personally, would use a 700 watt) and you can plug 20 lancelots into it. You can plug less in (say like 10 lancelots) if you prefer, so then you need only 300 watts (or preferably 350 watts).
Hardware installation:
1, connect the Power cable, use Molex-D-type connector or 5.5/2.5mm power plug. please do not use both of them.
As another option, we make our own, or find an off-the-shelf ATX breakout board. Possibly this might work
http://www.robotshop.com/cytron-atx-power-supply-breakout-board-right-angle-2.html though it does not have 20 of the 12V outputs.
I am not sure what the 5 (or 6?) caps on the cardreaderfactory ATX breakout board are for. If anyone knows, please let me know. Possibly they are just to help smooth out the 12V output. If that's the case, then it would be easy to add some caps to a generic breakout board.
The above options assume you don't mind doing a little soldering. THis is easy soldering, not like trying to solder SMT components or anything tricky.
