Limited availability on eBay: http://www.ebay.com/itm/NEW-Redhash-105-Gh-s-ASIC-Bitcoin-Miner-Avalon-clone-/321233038462?#shpCntId
Auction: https://bitcointalksearch.org/topic/tavs-auction-redhash-105-ghs-asic-miners-303379;all
Five months ago, I and two partners founded TAV (thinairventures.com), a company designing and selling ASIC miners. We have been operating in stealth mode, and today is our launch day! We are proudly announcing our first product: Redhash, a 105 Ghash/sec miner, available right now. We are selling a limited number of units in an online auction starting at 15 BTC per Redhash unit. The auction is denominated in bitcoins, but we accept various forms of payment.
15 BTC with units shipping now is clearly profitable: http://mining.thegenesisblock.com/a/44fc645248 (55% month-over-month difficulty increase), and even a pessimistic 100% month-over-month increase is profitable. Also, 15 BTC for 105 Ghash/sec beats the price per Ghash/sec of any competitor shipping now or in October!
Redhash Specs
Redhash is an improved Avalon clone Bitcoin miner:
- 105 Ghash/sec (320 chips at 328 MHz)
- Standard 4U/19" rack-mountable chassis: the feature most requested by Avalon owners
- Highly modular: 32 individually-replaceable hash units
- 100% compatible with 80-chip Avalon "modules" which fit the Redhash backplanes
- Easy to service: remove the top cover (5 screws), and no other screws or cables need to be removed or detached to replace individual hash units
- Best chassis and mechanical design for upcoming 2nd-generation Avalon ASICs
- Power consumption: 940W at the wall (120-240V), outputting 780-790W at DC (12V), making our provided PSU (Corsair TX850M) run at 92-93% of its maximum load
- Oversized chassis accepts all "long" PSUs such as Corsair AX1200
- Ships from the USA: no customs for US buyers
- Fans ignore PWM control - always run at 100% speed for maximum cooling (very noisy! You may replace them with standard PWM-controllable fans for quieter operation, but this necessitates downclocking below 328 MHz!)
- Warranty: Guaranteed working on delivery

Who we are
I am Marc Bevand (aka mrb), a longtime trusted active member of the Bitcoin community since December 2010. My first adventure with Bitcoin was to develop what was at the time the fastest GPU miner for AMD Radeon cards, hdminer. My business partners are Bertrand Darnault and Jonny Gerold. I have known Bertrand for 9 years, we both graduated from the same computer science school (Epita) from the class of 2003. And I have known Jonny for a little over a year, since we met as coworkers. All three of us are just as highly fascinated about Bitcoin as each other.
Why you can trust us
We understand that trust in a vendor is primordial in the Bitcoin mining world. We have done numerous things the "right" way in order to establish trust:
Ordering
The market has highly varying opinions on the value of ASIC miners. Therefore we decided to let the market determine the right price by launching an online auction to the highest bidder with a minimum bid starting at 15 BTC per Redhash unit (105 Ghash/sec), with minimum increments of 1 BTC. We have a limited number of units available in this auction: only 27 units. The auction starts now and runs for a few days. Auction winners will have 4 calendar days to make payment, which can be made in bitcoins, credit card, cash, cashier's check, or wire transfer. If paying in USD, we will convert your bid's BTC amount to USD according to the current coinbase.com exchange rate +/-1% that we will announce publicly the moment the auction ends. The Coinbase exchange rate is usually very close to the CoinDesk Bitcoin Price Index: http://www.coindesk.com/price
The auction takes place in the Auctions subforum, where the auction rules and payment details are explained in depth, see Auction thread.
Shipping
We ship worldwide, from southern California, USA. We will accommodate whatever shipping carrier you request at the time of payment: UPS, Fedex, US Postal Service, etc. Shipping is free (included in your bid) when using standard shipping (UPS/Fedex for destinations in the USA, and US Postal Service for worldwide destinations). If you request some sort of expedited shipping, you will be asked to pay for shipping in addition to paying your auction bid.
Alternatively, we offer local pickup (at our office in Lake Forest, CA, or at our data center in Irvine, CA). We will take 0.5 BTC off the price if you choose this option over shipping.
For international shipping, we highly recommend to ship the Redhash unit without the Power Supply Unit as its presence may cause issues at Customs during import. You should instead purchase a standard PSU on your local market (850 Watt minimum). Of course the decision is up to you, but if you choose to have the Redhash unit shipped without PSU, we will take 0.5 BTC off the price you bid.
Future plans
We want to make TAV the most trusted and well-respected ASIC miner vendor. We are working on future projects, but will not divulge any details. Do expect future announces, like this hard launch, that surprise the community :-)

Why you can trust us
We understand that trust in a vendor is primordial in the Bitcoin mining world. We have done numerous things the "right" way in order to establish trust:
- From the beginning, TAV's vision was to avoid offering risky preorders as they inflict stress and incertitude on customers. So, unlike the vast majority of ASIC vendors, TAV does not require preorders. Our miners are in stock, available today, already developed and working, ready to ship.
- We can prove we ordered 10,000 Avalon chips, which were used to build our Redhash miners. We sent 782.1 BTC from our address 1AAoyFmZuUbVpNUJFCCSJbZQSvSRm8vPad to Bitsyncom’s temporary address 1H9whoZUz1iNyBagMUrudw3AnoRqLHKpH5 on April 21, 2013. As seen in the blockchain, this amount was almost instantly re-transferred to Bitsyncom’s well-known address used for receiving Avalon chip payments: 1FGAftzSTztFSB8LMwsrdCKTyqGY6zr3sU. The message "TAV ordered 10,000 Avalon chips on April 21, 2013" has been signed with our sending address. The signature is G5bJki+cSGKJcVA27qI7vspAQnWc19n2VXvzxlsBR7/wO6fiavyoMIp/vPcUVlchtfMjnBeWXQn+ZYq96rFfVSc= and can be verified by anyone:

- On June 14, 2013, we were the first to demonstrate a working Avalon clone by posting a "teaser" post: https://bitcointalksearch.org/topic/first-running-avalon-clone-teaser-234173
- We have been testing all our Redhash miners (a bit less than 10,000 chips = approximately 3 terrahash/sec) on the pool Eligius for the last 2-3 days to publicly demonstrate that our hardware is working: http://eligius.st/~wizkid057/newstats/userstats.php/1NkkkghQHFNs8H1hAmKDM9fJo4mBkoHeej Notice the nickname of this address has been set to our company name "Thin Air Ventures" (TAV) on the pool's website.
- We provide multiple pictures of our chips, products, and facilities in this post as well as on our website.
- The company Thin Air Ventures, LLC was formed in the US state of Delaware. (However, do not confuse us with an LLC bearing the same name as us that was created and dissolved in respectively 2001 and 2005.)
- The WHOIS information for our domain thinairventures.com is de-anonymized and contains the contact information of one of our founders, Marc Bevand, as well as our actual office address in Lake Forest, CA, USA. (Note: no valuable hardware is stored on site - everything is in a data center).
- Anybody is welcome to pay us a visit at our office at 20331 Lake Forest #C7, Lake Forest, CA 92630. Please make an appointment ahead of time by mailing [email protected], to guarantee someone will be there to receive you at the time of your visit.
