The FutureBit MoonLander is an ASIC Scrypt USB stick miner made by jstefanop on Bitcointalk that is based on a single Alcheminer AlcheMist Scrypt ASIC chip. A small SCrypt-based ASIC miner intended to provide a hashrate between 0.4 and 1.2 MHS with a power usage of about 5W per megahash. The device is user overclockable with voltage adjustment available via a variable resistance potentiometer on the board and clock setting via the software miner. Using the device directly plugged into a USB 3.0 port you should be able to push it somewhere close to a Megahash with the available 4.5W of power, for more you will need a powered USB HUB capable of providing more power to the USB miner and probably active cooling. We have purchased a single unit in order to be able to try it out and see how well it performs, so you can expect our first impressions and test result from the FutureBit MoonLander very soon.

FutureBit MoonLander Specifications:
– Scrypt Hasrate: 400 KHS to 1.2 MHS performance
– Power Usage: about 5 watt per Megahash
– Voltage Adjustment: fully customizable core voltage range from 0.7 – 1.1v
– Power Efficiency: really efficient 5v->core voltage stage with about 95% efficiency
– Heavy duty/over speced parts were used to ensure wide range of operation (this thing can put out 20amps if you wanted to push it that far)
– Status LEDs for power, TX and RX transmission
– Uses latest bfgminer 5.4 for control and mining
– Will work with all Mac OS, Linux, and Windows based PCs

The price of the FutureBit MoonLander USB Scrypt ASIC miner is $39 USD plus shipping and you can order directly form jstefanop over at Bitcointalk or get it via some of the official resellers while they have units. There are two US resellers – Asicpuppy and HolyBitcoin and there is one reseller for Europe – Bitshopper.

Do note that these USB Scrypt ASIC miners won’t make you rich mining Litecoin (LTC) and even ROI won’t be very fast at the current moment, they are not meant for that. The FutureBit MoonLander is a handy little device that is affordable enough for people that want to experiment with Scrypt mining for fun. With that said however if you point the miner at some Scrypt altcoin with low network hashrate and difficulty, mine some coins and then sell them at the right moment you can still do pretty good.

The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin protocol according to the company that had made it – 21 Inc. That means the hardware to provide a constant stream of Bitcoin and the software to make that bitcoins useful for buying and selling digital goods and additionally developers can use the 21 Bitcoin Computer to quickly create apps, services, and devices that can be rented or bought for bitcoin.

The 21 Bitcoin Computer is a special board with an ASIC mining chip that is attached to a Raspberry Pi 2 chassis, and comes with a WiFi and power adapter, 128 GB SD card, USB-to-laptop cable, and everything you need to run it either as a standalone machine or to provide bitcoin to a Mac, Windows, or Linux computer. It comes with a full copy of the Blockchain pre-loaded on a 128GB SD card meaning that the computer will briefly synchronize with the network when you plug it in, after which point it will run as a full node by default without further intervention.


If you are interested what the dedicated ASIC chip is capable of, it seems that the 21 Bitcoin Chip has an efficiency of approximately 0.16 Joules per Gigahash and can calculate 50-125 Gigahashes per second. So apparently the focus is not only on providing you with a compact and not very powerful mining solution, but instead a device that can be used for supporting the Bitcoin network and can be used by users for offering goods or services taking payments in Bitcoin with the mining just adding a bit probably enough to cover the costs of running the hardware. You can already pre-order the 21 Bitcoin Computer for $399.99 USD and it will start shipping on November 16, 2015.

The $400 USD price tag is a bit steep if you consider the device as a Bitcoin mining-only solution due to the fact that it is not that powerful, even though it seems pretty efficient in terms of power usage even for the low hashrate it offers. It seems that was not designed to be used as a typical mining hardware like the other ASIC miners for Bitcoin, but instead the main target seem to be developers that are willing to write applications or integrate it as a part of a product or service that they are already offering as a means to integrate Bitcoin support. So miners are probably not going to be interested in the device, but developers might take some interest in this standalone solution, but it seems we’ll see what will happen in November when it hits the market.

After the recent announcement of the new BitMain BM1385 ASIC chips for mining Bitcoin or other SHA-256 crypto currencies BitMain has started taking pre-orders for their first miner based on the new chips – the Antminer S7. The new BitMain Antminer S7 miner has a more dense configuration than previous Antminer machines, using 162 chips in the same space that the S5 used only 60 in. The S7 uses just 1210 watts of electricity to deliver 4.86 terahashes per second of mining power per unit, so specification wise the new miners looks very attractive, especially when compared to older hardware.


BitMain AntMiner S7 Specifications:
1. Hash Rate: 4.86 TH/s ±5%
2. Power Consumption: 1210 W (at the wall, with APW3, 93% efficiency, 25C ambient temp)
3. Power Efficiency: 0.25 J/GH (at the wall, with APW3, 93% efficiency, 25°C ambient temp)
4. Rated Voltage: 12V+5%, should not be less than 12.0V
5. Chip quantity per unit: 162x BM1385
6. Dimensions: 301mm(L)*123mm(W)*155mm(H)
7. Cooling: 2x 12038 fan
8. Operating Temperature: 0 °C to 40 °C
9. Network Connection: Ethernet

You can get the new miner for $1823 USD or roughly 7.896 BTC with the current exchange rate. When you add a suitable power supply like the 1600W APW3-12-1600-B2 that Bitmain sells for $155 USD (0.671 BTC) and you factor in the cost of shipping and custom taxes, electricity and the slowly increasing network difficulty you are already looking in probably 8-9 months at least to get back what you have paid for the miner. So although specifications wise the device looks very good it is still slow to ROI in the current not so great for Bitcoin conditions, but then again this is probably the best Bitcoin mining hardware available to end users at the moment. You can already pre-order a BitMain AntMiner S7 from Batch 1 with expected shipping date announced as late September of 21~30 with a possible delay of up to 10 days extra.
