Block Erupter How-To: Share Win7 Internet Wi-Fi Connection

How-To share a WI-FI internet connection with your RJ45 connection

Connect your PC or laptop via Wi-Fi first. Be sure you don’t have any ethernet cable attached.

Go to Control Panel -> Network and Sharing Centre -> Change Adapter Settings on your WI-FI card
Right click Properties, go to sharing. Allow Internet Connection Sharing, click both boxes.

Share Wi-Fi Connection with Block Erupter

Your RJ45 connector receive a fixed IP : 192.168.137.1

Download BFGMiner for PC.

Create at batch file like this in the uncompress folder
Command line is :

bfgminer -o us1.ghash.io:3333 -u username_worker -p anypassword –stratum-port 3333 –set-device PXY:diff=512

Set an IP address to the Block Erupter, I set mine to 192.168.137.251.

Gateway, Primary DNS, Pool Address should 192.168.137.1. It’s your shared connection address from your PC / Laptop
Port number is set to 3333, need to change if pool need another port number. Set your ASICminer Tube or Prism clock.

Block Erupter Wi-Fi Proxy Connection Config

Open a DOS session, run CMD, type IPCONFIG /ALL. Confirm it’s good IP. Ping address.

Ok start engine, launch BFGMiner batch file with your settings and power up your block erupter hardware.

EVGA SuperNOVA 1300 G2 1300W Power Supply

EVGA SuperNOVA 1300 G2 80 PLUS GOLD Certified 1300W Active PFC ATX12V Full Modular PSU 10 Year Warranty SKU: 120-G2-1300-XR

I supply my ASICMiner Tube with a EVGA Gold Rated power supply. My miner need between 900W-1100W. No problem my Supernova G2 deliver nice powerful and quiet 12VDC current. Run very cold with my Tube attached to it in full OC mode. Recommended. You can buy it with Bitcoin at Newegg.com or .ca

Rules Of Thumbs : One miner for one 120V/15A circuits / Breaker. If you are running two without pop a breaker, you’re at the edge … be careful with your load.

ASICMiner Tubes Deep Inside

Deep Inside ASICMiner Tube

This is the DC/DC regulator use in Tube design to feed the BE-200 ASICs.

Part Number TPS53335 High-Efficiency 20-A Synchronous Buck Converter From Texas Instruments.

They can deliver up to 20A in a very tiny package. Input voltage range is 4.5V-25V on those little beast.

Need 8x DC/DC to supply 24 BE-200 ASIC to have a PCB board loaded. That 20A * 8 = 160Amps Abs Max or a lot.

Good DC supply and constant current is the key for a design to go well.
EMI and Ground loop can be a problem with high current circuits, high filtering is required.
Most of the components is capacitors of all sizes and big inductors. Only job : to filter DC on the board.


Observe all those nice ground planes, well done. Need more soldering on power connectors for sure. Production quality issues.
