than ever to get into ASIC mining on a small scale. Much of his work can be found on the mining hardware section in the bitcointalk.org
forum.
As of this writing, the best options available are the CompactF USB stick miner and the R909 pod miner. For the CompactF, a specialized
USB powered hub and cooling fan is also required (see list of options below). The R909 just needs a 12V 8A+ AC/DC Power Adapter
w\ 5.5x2.1mm Barrel Jack.
CompactF Power, Connectivity, & Cooling:
- 7 Port Powered USB Hub 3.0, 65W (Bitcoin Merch)
- 10 Port Powered USB Hub 2.0, 120W (Bitcoin Merch)
- 8 Port Powered USB Hub 2.0, PSU Not Included (Gekkoscience)
- Use the 12V 8A+ AC/DC Power Adapter w\ 5.5x2.1mm Barrel Jack
- Any USB powered FAN can be used for cooling
- Bitcoin Merch makes a 2" x 2" x 2" custom fan for the CompactF that is most ideal
To run these miners on Windows 10/11, cgminer.4.12.1.zip was downloaded and installed with the hash
ef9d202fad7b9501c0d5b05ac99b3ad1a5f9e09734fa6bc341f19398fbb0da6f. See Kano.is' download page for other versions. When
downloading and extracting, it will say the file contains a virus. The cgminer software has been included in many mining Trojans around
the internet operating without the consent of the user. that is not the case here; proceed to download and extract without fear.
The next item of business is install the driver (called Zadig) so the computer can to communicate with the GekkoScience miners.
Zadig 2.8 was downloaded @ https://github.com/pbatard/libwdi/releases. To install, run Zadig as administrator and if your device is
plugged in but you cannot see it, use the Menu: Options -> List All Devices and you should be able to see the device in the drop down
list as something like: "CompacF Bitcoin Miner" Choose the install or replace driver option and select WinUSB. Do this for each miner.
Note: When you first switch a device over to WinUSB with Zadig and it shows that correctly on the left of the Zadig window, but it still
gives permission errors, you may need to unplug the USB miner and then plug it back in. Some users may need to reboot at this point.
Next, Create Configuration File (gekko.conf) and save it in the same directory as cgminer.exe.
- {
"pools" : [
{
"url" : "stratum+tcp://$IP:$PORT",
"user" : "$MINING_USER.$WORKER",
"pass" : "x"
}
],
"gekko-r909-freq" : "450",
"gekko-r909-detect" : true,
"gekko-compacf-freq" : "400",
"gekko-compacf-detect" : true,
"gekko-tune2" : "60",
"suggest-diff" : "1"
}
To Run, First Create a Shortcut to execute "cgminer.exe -c gekko.conf".
Make sure to copy that shortcut into the system's startup folder so it will run each time the computer boots or restarts.
That folder can be quickly opened by pressing "Windows Key + R" and running "shell:startup".
