As promised PCB "porn"

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 remember someone advertising a similar service, but you had to just point your miner at the server. I was somewhat skeptical about it though since it was a homemade operation... I think this is a great idea, they just need to up the hashrate and make it so you don't need a PC. Anyone know of a legit blockchain lottery you can just point your device at?  

Forget using Rpi. You can use TPLINK TL-MR3020 as controller, price about 20 USD. Buy it at your local computer store 

This seems a much more sensible device than the Bitmain U3

It has a higher hash rate
The power consumption and therefore heat dissipation is such as to make it a reasonable domestic heating device without it being excessive in a European winter
Because of the rectangular construction and horizontal heat exhaust, they are amenable to stacking vertically
One can choose the power supply one wants
The comparison with a lottery device is clever

At £0.15 per KWh it would cost £3.024 per week to run if one assumes it requires 120W
With Bitcoin at €300 the expected return per week would be (25*300*6*24*7)/2000000 = €3.78 (One over 2 million is the chance of it finding a block in each 10 minute interval.

On the minus side delivery (to the UK) is €32 giving an all in cost of €110 ?
I have not factored in the price or running costs of a Raspberry Pi, SDHC card and power supply
The technical information is sparse. (absolute maximum ratings ?)

Then there is the question of reliability - On Technobit's website (for another product) there is a cgminer screen.  It shows the best share as 73.1K for a hash rate of 368.7 GH/s - this suggests a short test duration (looking closer 6 minutes in fact).

If you would normally use 120W 24/7 for heating, the expected bitcoin return would cover the device cost in approximately 30 weeks (with no increase in difficulty)

£1 = €1.2 approximately

Yes it works without hub.
The problem with hex4m is that we did not have enough resources( too many buffers-> less space for USB one) in the MCU so hex4m uses the hub as an external buffer for usb comms

does it work without usb hub?
tp link does not work directly with hex4m

have you tested this?

thanks

A bit of a premature roll of the dice going on there :p

This is not right, you should be horny after seeing the picture, not before 

I am Horny and eager to see it also

Kk

I'll be able to do it monday/tuesday

Pcb shot plz with sugar on top (miner porn)

You can always got a 20 USD TP-link, flash it with FW from our site and leave it mining unattended

nice looking device for mining entry/lottery play but should not need a pc for use. 

much more useful if it had a built in controller so you can just plug it in and forget about it.

Wow, thank you
fixed
 

marto74 you have a porn misspelling on your product page. "/blcockchain"

2.5

it looks like the 5.5mm... can't be both 

yes
