whats the distance between the USB ports on the 8 port? they would need to be atleast 13mm apart i guess?

just measured mine and they are 25mm across.

any news on this? i havent been anywhere near mine to measure them...

I'm running BitCoin, LiteCoin and FeatherCoin clients on my PC (not the mining software) - i'm not using the wallet features anymore on this machine - is there any point running them? does it help the network with having them running?

what kind of overhead on my machine would it cause having them all running?

I'm loosing about 600MB of RAM to the 3 clients but what about CPU/HDD and network...

apparently you 'can' overclock the CPU - i dont know how or to what value - i'd definately investigate cooling - as i've seen people say they've over clocked to 800mhz

just googled and found this:

http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-overclock-raspberry-pi/

1000Mhz and much improved RAM speed? I think thats a win BUT i'd definiatly want a cooler on the chip

so its a maximum of 127 devices then...

precisely the thing we need to do

that .19 makes a massive difference if looking at ROI

plus buying some of these cheaper WILL overall reduce the cost of the original purchases - my two have returned 0.4 BTC since recieving them and setting them off to mine so i still have a long way to go to recover my 4.2BTC originally spent but if i buy two more @ 1BTC each the overal cost for USB miners will be 6.2 BTC and i will have doubled my hashrate... not that the ROI will be much shorter!

As I am in the UK and as the import/customs taxes are a stupid amount im more interested in anyone with experience shipping to the UK or already in the UK.

i have had a few people offer me cards at prices where i can buy them brand new cheaper due to the shipping costs or where they are damaged - please only offer cards that are a reasonable price or in fully working (game stable) condition - im not expecting people to give them away either (although am happy to accept it )

can't quite tell but have you put a heatsink on the CPU?

i would assume that the hard limit would be 127 *2 USB devices? depending on whether the the two USB ports are separate controllers...

i agree the dimensions seemed a little generous - i'll get better ones this evening

alos any ideas what the max rated power draw on the 4 or 8 port is? the USB Block Erupters need 500ma each? so for 8 thats around 4A right?

A quick google came up with this:

http://www.amazon.com/ASICMiner-Block-Erupter-300MH-Sapphire/dp/B00CUJT7TO

Product Dimensions: 3 x 1.4 x 0.5 inches

I'll measure mine when i get home otherwise

fingers crossed - you can mark me up for 3 if they are doing a 1BTC refund per chip

is this not a bit expensive now as the FPGA board does around 5-6Mhash for 70 and the USB Asic does 333 for around the same? (based on 0.99 BTC) (GBP prices)

where are you located?

I'm guessing that getting a group buy in the UK is out then :S

my understanding of this is that IF AC gets over 1000 orders we'll all get a refund for the original purchases - so if i order 4 miners (prevously ordered 2) i should only have to pay around 2 BTC? if so i'll order 5 new ones

havent they just dropped them?

should be USB block Erupter - not exploder typo in the OP - will correct it
