FutureBit Project Apollo: Bringing ASIC Mining Back to the Home Miner

31, Aug 2018

An interesting new project from the developer of the FutureBit Moonlander and FutureBit Moonlander 2 USB Litecoin ASIC miners jstefanop called FutureBit Project Apollo. The new device called the FutureBit Apollo LTC is trying to be the world’s most efficient Scrypt ASIC miner, using WiFi and actually being silent… and if it is available at a good price point we are sold. It is targeted at home miners that want to get into mining and/or play around with ASIC miners and not large scale mining operations and mining farms, though it might be interesting for bigger miners as well thanks to the promising specifications announced.

FutureBit Apollo LTC miner Prototype Specifications:
– Compact Stand-alone Pod Style Miner (4x6x4in).
– Very wide range of operation modes with preset ECO (quiet) mode and TURBO mode.
– 100-140+ MH/s of Scrypt performance per miner.
– Industry leading 1W/MH in ECO mode, and 1.4W/MH for TURBO (100-200 watts).
– Powered by a fully integrated Quad-Core A7 ARM based controller.
– First miner to be fully controlled over wifi, only cable needed is power! (this will be a Beta feature on launch..backup ethernet port is available as well).
– Clocks and Voltage is fully customizable by user with easy to use interface (no more pots!).
– Industry leading 97% efficiency 12v power-stage, with 27 ASIC chips powered in a 3×9 parallel/serial power arrangement.
– Custom designed cold forged hexagonal pin heatsink with leading thermal performance for the quietest ASIC miner in operation!
– 2k-6k PWM High Static Pressure Dual Ball Bearing Fan with automatic thermal management with onboard temperature sensor.
– Controlled via local connection on a web browser similar to antminers. You can simply set it up via smartphone browser. No crazy driver installs, hard to use miner software or scripts needed.
– Two Six Pin PCIE power connectors for wide-range of power draw (only one is needed in ECO mode).
– New future platform features including full-node/peer to peer fully decentralize mining, full stand-alone solo mining, cloud/app based controls and more in development.

According to jstefanop the device is ready for mass production and it will be available in pre-order batches just like the previous Moonlanders. The first batch will be a VERY limited run (under 1k units) in order to fix any production issues with expected price range of $200-300 USD (it is not easy to beat large scale manufacturing in China) with better price and better efficiency. The first batch will probably be available for October delivery to people that pre-order the device in a first come first served basis. All of the initial sales for the Futurebit Apollo miner will be handled through the official Futurebit project website, though later batches will probably be available through resellers.

FutureBit Moonlander 2, An Upcoming Scrypt USB ASIC Miner

30, Aug 2017

Last year we have tested and reviewed the FutureBit MoonLander USB Scrypt ASIC Miner and have found it to be a well-designed and working miner. Unfortunately with hashrate maxing at just about 1 MHS at that time it was not very up to date for practical use with mining profitability in mind. The good news is that there is a new version of the miner in the works – FutureBit Moonlander 2 and the new device will be more interesting specifications wise.

The FutureBit Moonlander 2 USB Scrypt ASIC miner is supposedly offering an efficiency of about 1.3 Watts per MHS and the device should be capable of delivering between 3 and 5 megahashes for Scrypt mining (depending on settings). With the recent peak of the interest in Litecoin we could be seeing increased interest in these devices as well. The new version of the USB Scrypt ASIC should most likely be available for orders in October with deliveries starting at the end of October or early November. The price is not yet fixed, but it will most likely be in the range of $40-$60 USD per miner.

Preliminary specifications of the miner:
– Hashrate: 3-5 MHS Scrypt performance per miner
– Power usage: about 1.5W per MHS for most of that range
– Operating frequency: core clock from 500 MHz to nearly 1 GHz!
– Operating voltage: fully customizable core voltage range from 0.6V – 1V
– Fully redesigned 5v->core voltage stage with about 95% efficiency
– Heavy duty/over speced parts were used to ensure wide range of operation (stick can be pushed to nearly 6mh if you can cool it)
– Status LEDs for power, TX and RX transmission
– Uses latest bfgminer 5.4 for control
– Will work with all Mac OS, Linux, and Windows based PCs, as well as RPi’s etc (and I will be offering easy to use pre-compiled binaries)

Trying Out the FutureBit MoonLander USB Scrypt ASIC Miner

1, Apr 2016

futurebit-moonlander-usb-scrypt-asic

We have been playing around with a FutureBit MoonLander USB Scrypt ASIC Miner for a few days already and it is time to share our experience with the device. We should start by stating that the FutureBit MoonLander is a small and not very powerful in terms of performance USB miner that is more for fun than for profit. The device is intended for people that just want to play around and experiment with a small and not very powerful Scrypt ASIC that is available at a low price. The miner uses a special version of bfgminer 5.4 (source).

futurebit-moonlander-overclock

The MoonLander can run on a very wide range of speed and efficiency, allowing the user large headroom for tweaking and playing around. The device comes with a variable resistor on the PCB that allow the user to adjust the core voltage (0.7-1.1V) and a wide range of operating frequencies that can be set via the software (104 MHz to 400 MHz). Of course you need to be careful playing with these as increasing the operating voltage past the default level of about 0.75V and going past 264 MHz would require the usage of powered hub and active cooling for the miner based on our experience. The official information about the miner performance cites a value of 2.77 KHS per 1 MHz, so the lowest frequency should be able to provide about 288 KHS hashrate for mining Scrypt crypto currencies and the maximum of 400 MHz should result in around 1.1 MHs.

futurebit-moonlander-bfgminer

With a hashrate in the range 0.288-1.1 MHS for mining Scrypt-basec crypto currencies you will not be able to mine much and you will also have to look for mining pools that offer user adjustable difficulty level or support low fixed difficulty. If we get back a few years to the times of Litecoin mining with GPUs we can say that this miner gets you in between half to almost two high-end GPUs worth of Scrypt hashrate. Of course the power usage of this USB Scrypt ASIC is much lower than what a high-end video card consumes, but then again at these low hashrates you will need many months to even earn enough to cover the cost of the miner. Anyway, our goal was to see what you can get in terms of performance with the FutureBit MoonLander miner by powering the device with a regular USB 2.0 and USB 3.0 ports with their power limits that do not allow the miner to reach its maximum performance. You will need to use a powered USB hub in order to be able to overclock to the maximum the miner, a 2A powered hub should allow you to reach the 10W maximum power and you will also need to provide a serious active cooling to the device if you want to push for higher core voltage and the maximum supported frequency.

futurebit-moonlander-thermal-1

Out tests have shown that the default operating frequency of the device set at 144 MHz is what is possible with a USB 2.0 port capable of providing 0.5A at 5V or about 2.5W. With this operating frequency and using the stock core voltage of about 0.75V you can expect to get around 400 KHS worth of Scrypt mining power. On the thermal images above you can see the operating temperatures at these settings, the AlcheMiner ASIC chip does get hot with temperatures of around 55-56 degrees Celsius and the heatsink on the back is at about 44 degrees Celsius. These temperatures should not be a problem for operating the miner without any additional cooling on the long run, unless of course the ambient temperature is not very high.

futurebit-moonlander-thermal-2

Going for the higher power limit of USB 3.0 ports that are capable of 0.9A at 5V or about 4.5 Watts of power you can push the device to an operating frequency of 264 MHz. Any higher and the power provided by the USB 3.0 port will not be sufficient enough to keep the miner operating properly. The expected hashrate at these settings should be around 730 KHS, a result that is not bad but we were hoping for a bit more. Apparently achieving 1 MHS or more will be possible only with the use of a powered USB hub that can provide more power to the USB miner and 2A is needed for pushing things to the maximum along with cooling fans as already mentioned. It is important to note that the thermal camera photos show an increase of about 15 degrees for the ASIC chip and about 10 degrees for the cooling radiator when using USB 3.0 as compared to USB 2.0. Note that at this level adding some airflow around the miner is a good idea in order to keep it cooler as otherwise it may overheat after a while, so it will be a wise idea to monitor the operating temperatures.

All in all the FutureBit MoonLander USB Scrypt ASIC miner is a fun little gadget to play around with and that is what it is for – playing around with an affordable ASIC miner. It is not intended to be profitable or to make you a lot of money, it is for people that are curious like us and love to play around with tech. The next thing we are probably going to do with the device is to improve on cooling and try with powered USB hub and some overvolting and more serious overclocking of the device. Do note that increasing the operating voltage and trying to max out the operating frequency can decrease the live of the mining hardware and even damage it permanently if you are not careful what you are doing!
