how do I wire 2 block erupter cubes to a single supply

[sandman102]

I am new to mining, just ordered my first cube and I have a Corsair RM1000 PS from another project.

If I want to add a second cube, can I add it to the same PS?

What kind of cable harness do I need t split the supply, and are there harness's available commercially,  or do I need to make one?

Thanks

This tutorial is very good.

I have 2 cubes running off a Corsair Gold RM850.  The PS has 2 PIC/E power lines.  Each cube is attached to one.

Power is provided by 2 pci-e connectors from psu.  You can also use molex to pci-e adapter.  I believe for each cube you would need to run a separate mining proxy.  I may be wrong.

i don't have one but i have seen some impressive set up's with a raspberry pi running a load of these,  ( i have raspberry pi not eruptors !)

I have a raspberry pi acting as a proxy and running bfgminer with several cubes.  I have been running it for months.  No problems other than the very very intermittent bfgminer crash/restart

My power supply comes with 4 6+2 PCI cables, am I correct in assuming that each erupter requires 2 separate cables?

The reason I ask is because on each of my cables, there are are 2 6 pin connectors at the end of each of cables.  Am I correct in assuming that I use 2 cables for each erupter, and not use the second connecter on the cable?

You can go either way.  Ideally you would use 2 cables though.

I have a cube running with 2 cables and I have another cube running with 1 cable - 2 connectors (each cable has 2 connectors for power)

Also, if you wanted to use a raspberry pi as the proxy and bfgminer here is the code:

sudo apt-get update
sudo apt-get install autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libmicrohttpd-dev unzip
wget http://luke.dashjr.org/programs/bitcoin/files/bfgminer/3.8.0/bfgminer-3.8.0.zip
unzip bfgminer-3.8.0.zip
cd bfgminer-3.8.0
./configure
make
make install
./bfgminer -o pool -O user:pass --http-port 8330

**replace pool and user:pass as necessary**
Example ./bfgminer -o stratum.btcguild.com:3333 -O minerguy_1:12345 --http-port 8330

I was planning on using a old xp box thats just sitting around and mining-proxy.  What are the advantages to using the pi?

Uses less power (something like 10 watts) than computer (100-500 watts).

The mining proxy is super easy to use but is limited in the info it gives.  You can use either 1 cable with 2 6 pin connectors or 2 cables with 1 6 pin connector for each unit.
