It is a project that I trust. With the history of the ICO this shows a decent backbone.

Hello.
Just came across this posts about the blue-, red-, ...fury USB miners. And I'm a bit curious if this miners are still in use? It's a kind of personal interest 

I have some empty PCBs for building Redfury/Bluefury USB miners left. If you have some soldering skills you can assemble your own Redfury/Bluefury Bitcoin miner.

I guess this becomes interesting since another batch of Bitfury chips is available. Therefore, I would like to sell these PCBs because I don't need them anymore.
Is anyone interested in it?

Nobody interested in it?

I ship from Austria (Europe). If you want to buy them seperately, you can visit the online shop http://minecoin.net/shop

Hello,
I have a couple of Twinfury miners in hand and I would like to sell them. You can buy

Here it is: http://minecoin.net/wp-content/uploads/2014/01/Twinfury-Firmware.zip

I guess I missed it to post it into the post. Sorry for that.

Maybe, some of you have already noticed that we lowered the price again for the Twinfury.

Sorry, I think I have missed your message. Got some of them as response of my post.

Shipping costs will be added. For Germany add 0.05BTC

Here, I would like to sell 10 pieces. If you want to buy a single one, visit the shop at http://minecoin.net

The devices are already packaged in an anti-static bag. But, I made a picture of them.
How is the escrow thing working. I haven't done it before.

Hello,
I would like to sell a some of my Twinfury USB ASIC miners. You can find some information about the miner in this thread: https://bitcointalk.org/index.php?topic=345294

The offer is:

If you are interested write me a message or post in this thread.

If you want to use the voltage scaling feature (which requires to assemble a resistor), you should update the Twinfury.

Hello,

I published a new post on the minecoin.net website about the firmware update for supporting the supply voltage scaling of the Bitfury chips. If you are interested, have a look: http://minecoin.net/firmware-update-for-voltage-scaling/

Anyone else interested in it with an decent offer?

Well. I'm not sure if my product is too big. If you have to use 3 USB ports to achieve the same hashrate with Antminers, it is the same as using one USB port and two others are not accessible. So, this doesn't really count.

85 EUR isn't doable. The Bitfury chips used for the miner were about 19 EUR per piece (means 38 EUR only for the hashing chips per miner). I cannot start talking about 85 EUR. Sorry.

Hello.
I just wanted to ask if someone is interested in buying a number of Twinfury USB miners. The specified hashrate is between 4.5 and 5 GH/s.
You can learn more about the miner in this thread: https://bitcointalk.org/index.php?topic=345294

Let me know if you are interested!

Best regards!

I almost forgot to say that we are slowly running out of stock. We have only about 50 units left!

And we enabled the discount if you order more units

• 5% discount if you order 5-9 pieces
• 10% discount if you order 10+ pieces

We are back from the holidays and are ready to take your orders. We also lowered the price to 240 Euro.

Very important... we modified all the remaining units to support the voltage scaling feature. This means that you can adjust the supply voltage for the Bitfury chip by software.

A higher voltage level means the Bitfury chip is probably hashing faster.
A lower voltage level means the Bitfury chip is probably hashing slower but is more stable with USB 2.0 ports.

The feature is available from bfgminer:
Press M, select the device with the cursor keys and press V to adjust the supply voltage. You can enter the voltage in the range of 800mV and 950mV. But you will need some active cooling fan if you increase the supply voltage.

nwoolls has written a great how-to for running the Twinfury miner on Mac OS X:

Many thanks to nwoolls!
