Offer still stands. Good luck trying to ship one of those without damage.

I dont think people in this thread are doing this for sick profits. They are doing it to prove it can be done, or for the fun of it, or because they like electronics.
BE cost less than $10 USD now so of course it is more economical to just buy more units than to spend money and time overclocking them (if you really wanted to get a 30% overclock, you could have just paid more and got a blade, which is more economical than an equivalent number of block erupter USBs and more or less 'supports' overclocking with the turn of a screwdriver or two and a few settings changes. (Although, of course, yes, there are better options than blades now, your money could be better spent, etc etc).
Definitely doing the BE mod's for fun. Best part is that I can do it at work and I get all my parts and electricity for free  |

Got bored today and OC'd 10 more eruptors that I picked up cheap on eBay. Just so happened, last week, I was placing a DigiKey order for work last week and added a bunch more SMD crystals and resistors in case I decided to do any more overclocking for fun or anyone who is interested. For fun, I found some abnormally sized heatsinks that could easily fit 10 eruptors. I have yet to have time to mill the surface and drill the holes, but I will get around to it .... I still want to try trying a peltier cooler on one just for fun. I would use some type of temperature controller (arduino based) so I can avoid condensation. Having lots of 20A 5V PSU's around is handy ... same as having a function generator. I am curious to see how far I can go with a peltier cooler while bypassing the onboard DC/DC regulator circuit. Pics will come! But for now, here is my latest 10 from today. (There is a stock one in the middle somewhere for comparison). FYI, Some of these are clocked at 16MHz with R1 replaced with a 1k2 resistor, the others are 16.345MHz with a 1k4 resistor. Cheers!     |

I'll drive up to Boston and pick it up for $1500 cash.

Can I keep my one bid @20 and add another unit @21 ? Total: 1@20 and 1@21  Also, is there still a 0.5btc price break for each unit shipping without PSU? Thanks |

Hey mjgraham,
Do you have any close up pics of how the heatsink is contacting the ASIC? I just found some MASSIVE heatsinks that I want to use for the bottom .... just need to figure out the top ones.
Thanks!

The 1276-5275-6-ND is not available for Digikey, this is the next best replacement I could fine: RHM1.2KCHCT-ND
Anyone see an issue with this? Thanks

How much are you selling the Avalon chips for each? What about 100? Please PM me your quote. Thanks

Is there any other hardware that is easily available besides Block Erupter Blades and USB devices?
I am also looking for chips that are readily available for my own PCB's I would like to start fabricating.
Thanks !

If your hub has a external powered DC input (which I would assume is 5VDC), you can use another of the same voltage adapter with a higher amperage rating. This would be able to supply the current to all the devices you have on that hub without running out of juice. You DO NOT want to increase the voltage going into the hub

Does anyone know a reputable supplier of actual ASIC chips? I don't see many Avalon or Bitfury chips in the wild really and what seems to be available is only BFL credits (which is a joke.) Thanks!
