My company is working on small electronic device to manage multiple bitcoins miners.
The goal to achieve is build small cheap device, which will be able to physically reset mainboard after detecting mining failure.
- based on arduino chip
- Ethernet module (with DHCP support)
- supply with almost any power supply 5-15V or even battery
- emulate reset (button press) up 8 mainboard using 2m pair cable
- reset is started by http API command
API command will be submitted by some external rig checker (by snmp, ssh, http) which submit command to reseter after detecting miner failure.
Future version will have built in checker (snmp, http) and external host wont be necessary.
I know there are managed power control unit from Avocent or APC but they cost at least 300$ and they will always need external host to check.
Suggested price for this device will be about 100-140$ - depending on some parts cost price (case, psu, goldpins)
There is also possible to build a device with support up to 128 mainboard (for some rig farm)
Please tell me what do you think about my project and are you interested in buying such device for your farm.
I will post video of working device very soon.
