I would like to get some info about the noise level ... the specifications says ~20 DB at 25 °C ambient temperature ... is this true and is this at max load @160 GH/s? Is it equipped with some high quality 80mm fan that adjusts speed in accordance with the temperature?

right ordered a tp link , but still cant get windows to see it for what it is 
i`m getting a few ghs out of it and a lot of
HEXM 0 CHIP 0,1,2,3 last received nonce 2 secs ago reset
 and it see`s
0: HEXM 0  : 1016  805/0802mv 20.12gh ....... this is on cgminer technobit win 0-3-8
i`m using 2 cm750m to power, (but can mod a 2kw server psu)
i`m a bit concerned because its a 2hex4m but i can only see 1 on cgminer screen
anyone got any ideas???
thanks mike

Unless I'm misunderstanding, this is just a USB based Bitcoin miner. Marto's suggesting you can run a solo node or use ckpool and try to solo mine a block, but you can use this to mine on a pool as well. The DICE themselves aren't winners, it's just Bitcoin mining.

Your formula appears correct though, with the following assumption that difficulty doesn't change either from outside sources, or you buying enough to affect difficulty.

Thanks dogie and thanks zich
I'm going to have a play, and get a tp link
hopefully I'll have it sorted soon
is it possible to run the hex4ms and the hex8A1 together?
Cheers Mike

The people that "They" are is Ckolivas and if i recall correctly, Kano too.
They are the people who run and maintain CGMiner.
Any drivers for hardware that use CGminer is licensed under the GPLv3. This means that the source to any modifications that the hardware makers make to CGMiner code MUST be provided by law if the hardware makers distribute modified binaries.

if they do not, they could get sued

Technobit has offered the drivers as open source, but they better not just throw a blob of code up on the net and call it a day.

If the hardware developers do not give documentation on how the "open source" drivers work with the mining software, things are not going to work properly. Both Luke-JR and Ckolivas will require this.

EG: Rockminer made drivers for CGMiner 4.3.3, making the "New R-Box" run at 110Ghs, but there was a new version of CGMiner out with a security patch.
The devs (Ckolivas) attempted to implement the new modified drivers into the new 4.7.1 and 4.8.0, the drivers are not working correctly. Because Ckolivas does not understand how the drivers work, he needs documentation to get it running correctly. all that Ckolivas can do is modify some numbers and code to get something out, but CGMiner 4.7.1 and 4.8.0 does not run the "New R-Box" at 110GHs but at 80Ghs to 50Ghs.
Some people are lucky to get it working at 120GHs with it, but not all.

do you understand now? technobit better not follow rocketminer.
and i dont mean in the way of making a little mining box like the R-box's, i mean in the way of ignoring the software developers of the mining software.

a patched version of cgminer does not mean documentation to the developers of cgminer so they can implement the drivers for said device correctly.
If technobit has the drivers and gives them up in the fork tree of cgminer, unless technobit tells them how to edit and modify the drivers, its up to technobit to implement it correctly. so guess what, when a new cgminer comes out, no updates to the drivers are going to be implemented, any security holes, memory leaks, chip killing code will be present in the next patch and there after...

well yeah, i have a old 'buntu'ed eeepc701 doing the mining work with the latest cgminer, I'm not going to use a cloned "our own custom mining software" version of it, call me paranoid, rockminers version spat out 120GHs on their "New R-Box" with 50% errors, but no other software could pull 80+GHs at less then 10% errors.. i suspect they did some calculation spoofing..

The full prototype hashing

Great guide dogie
I've followed it to the T, but my pc and zadig keeps seeing it as a hex8A1 which I have got 3 running fine. Any ideas that could help a noob?
Cheers Mike

It doesn't specify on them what chips the hubs use. One is of the Pi Hut's own brand, the other branded Cerulian from Maplin, both are 7 port with 2 amp supplies (though I have both powered by the ATX PSUs that power the miners). The way it behaved seemed to be down to lack of power on the USB bus rather than incompatible hardware as when I added the second powered hub, everything worked. As I am typing this I have 3 HEX16Es, a HEX8A1 and a Gridseed Dualminer all connected to the same Pi, all running stably using cgminer.

So fighting with these machines for several weeks now I have found out a couple things:

1. These things are so temp sensitive that I don't see them running autonomously without being installed in a climate controlled environment. Not the heat - but the cold. If I fire them up from cold, or I turn on the vent to full, they will cool down to the point of not even hashing. They don't start to hash halfway stably until the room hits at least 70F+. I shut off the vent for too long and it overheats everything else. This makes me feel like I'm dancing on a wire rope.

2. IR Gun every hashing boards and look for boards that are running 2X+ times as hot as normal hashing boards. These need to be pulled as fire hazard, they may be affected by #3

3. The laminate on the bottom of the pcb/hashing board is VERY thin. One scratch here will reveal the copper substrate inside the pcb and will invariably lead to a short to the heatsink and fire is likely.

I run cointerras, S1, S2, S3, S4, BFL, BTCGarden, ZeusMiners in every flavor, Gridseed G-Blacks, SP20's... This was my very first RMA, flame out and hardware exploding miner, power supplies excluded.

I've hacked together cables to run all three from a single psu, using all the 12v lines from all the unused sata and peripheral cables to gain the extra pcie cables it needed. I've had it running for a while at that setting without getting too hot.

I had problems with the raspberry pi not detecting all of the miners at the same time (each worked individually) and some of the other usb devices working erratically when all were connected via one hub, so I swapped that for a powered hub which improved things except still only detecting two miners, connecting the miners via a second powered hub fixed it.

Thanks for the suggestion   I have been toying with the idea of buying one of these.

I still like the idea of using a Raspberry Pi B+.  I think one could connect 4 of these miners as it has 4 USB ports and I could compile cgminer on it if needed.  I would run tightvnc on it so that I could monitor it remotely.

Perhaps one can do all these things with a TL-MR3020 (except for the 4 USB ports) if flashed with the appropriate firmware but I suspect that the Raspberry Pi's community would help me think of other applications that I could run at the same time.

I am not aware of any such rules. If there is I will change the requirement.

Think we need to fix the sigs.

They're bit messed up in Opera browser (for every rank).
In firefox, senior sigs don't look as they should.
All looks fine in IE.
Not sure about other browsers.

i just Register in the first one ActionCrypto.com Thanks for recommending that
This one is escrowed by redsn0w  good luck

It was about 75f.

Not sure if your joking or serious but that's the board that was facing down and caught on fire after running a few days at 220mhz in a cool well ventilated space.
