BitChimney Setup Instructions

  1. Connect the Ethernet cable into the Ethernet port on the front as shown below.
  2. Connect the IEC C13 end of the power cable into Bitchimney and plug the other end into your power socket
  3. Wait for about 15 seconds for BitChimney’s Vonets VAP11G-300 Wifi Bridge to broadcast its setup WiFi network.
  4. Using a computer or mobile phone connect to Vonets Wi-Fi network named VONETS_2.4G_XXXX. Password is 12345678
  5. Open http://vonets.cfg or on an internet browser on the device you connected to Vonets Wi-Fi network.
  6. On the login page that appears enter ‘admin’ for both username and password and click on Login button.
  7. On the page that appears, click on the wizard tile.
  8. You will see a list of available WiFi networks. Select the one you want to use for BitChimney and click Next
  9. Enter the password of the selected WiFi network and click Apply. (Please make sure to enter password accurately, failure to enter the right password will require restarting this process)
  10. Click on Reboot.
  11. Wait for about 2 minutes for Vonets WiFi bridge to reboot. You can then locate Bitchimney IP address on your Network using an IP scanner, BTCTools, or other network scanning software.
  12. Login to Bitchimney webUI using IP address. Password is ‘admin’.
  13. Configure pool and workername, then click save.
  14. Bitchimney comes configured with two performance modes. Normal Mode at 70TH/ ~750Watts and High Power Mode at 100TH/~1000Watts. These two modes are fully autotuned before shipment.
  15. You can try other modes to get various hashrates and thermal output. Autotuning for each mode takes about 4 hours. We do not recommend hashrate targets over 100TH since those may cause overheating and damage to the device. Bitchimney PSU can not provide the higher voltages required for overclocking needed to get >100TH hashrate.

  1. Single Antminer S19 Hashboard (You can use any existing hashboard or purchase one from us). All S19 hashboards fit inside the bitchimney case except the 88 chip S19 models. 
  2. Bitmain APW3++ Power Supply (modified to output 13.6V)
  3. Xilinx Control Board
  4. Signal Cable
  5. Loki Kit
  6. Four 4 AWG 1/4″ & two 18 AWG 1/4″ ring terminal connectors
  7. 4 AWG Copper Cables (two cables , 9 inch long each)
  8. Crimping Tool
  9. Vonets Wifi Bridge
  10. 4x 120mm PWM fans (option A, option B)
  11. 16x M4x45m screws & 4x M3 x 10mm screws
  12. Power cord
  1. Modify your APW3++ PSU to higher voltage needed for running S19 series antminers. We choose 13.6V for most of our S19 builds since this voltage is sufficient to run most S19 series single hashboards upto 1200Watts (APW3++ wattage upper limit on 120V). Procedure for voltage modification on APW3++ PSU is listed on Pivotal Pleb Tech’s voltage modification guide.  
  2. Attach ring terminals to the two 4 AWG cables using a cable crimper. Strip the ends off of Vonets WiFi bridge power cable, and about a 6 inch section of 6-pin molex connector. Then connect these cables to the modified APW3++ PSU as shown in this image. Make sure to double check the polarity of the connections. Incorrect polarity will damage the hashboard & other electronic components in the build.
  3. Before you start the assembly, here’s a parts diagram for your reference. All 3D printed parts snap-fit via tongue & groove joints.
  4. Attach the stand to the lowerbody.
  5. Then screw on the 120mm fans using M4 x 45mm screws.
  6. Attach the 120 mm fans to upperbody using M4x45 mm screws
  7. Slide the hashboard into the hashboard slot as shown in this image
  8. Insert the PSU into the PSU cavity and route the cables as shown here
  9. [Optional] We use cable ties to strap down the PSU and an insert to prevent it from moving around while shipping. This is not needed for building the unit in place. 
  10. Attach the upper body to the lower body. 
  11. Align the faceplate to the Xilinx control board, and then mount the control board to the side of lowerbody using four M3 x 10mm screws
  12. Connect the two PSU power cables to the hashboard. Connect the 4x PWM fan cables, Control board power cable (yellow and black, 6 pin molex connector), ethernet cable, hashboard data cable and loki kit to the control board as shown below. Make sure to double check the polarity of the hashboard power connection. Reverse polarity will cause permanent damage the hashboard. 
  13. Attach the Crown to the upper body. Your Bitchimney unit is now ready to be powered up. 
  14. Power up and connect to WiFi, then login to the webUI to enter your pool credentials
  15. Bask in the glory of quiet ASIC heat!
