I'm selling 4 pin molex power connectors for gridseeds. Multiple types available, see here:

https://bitcointalksearch.org/topic/m.5650838

What's the wire gauge in the 10-connector? You are dangerously close to 6A on the standard molex connector with 10 units as it is, and that splitter cable looks awfully thin. I wouldn't connect more than 3-4 miners via molex, and I wouldn't use this kind of splitter unless it is rated for 10+ amps. Is that black electric tape on the joints? Can't see well, the pictures are too blurry.

And the gauge of the the wiring you used? Specifically the black 10-way splitter, and the yellow wire? Thanks.

I didn't see your question sorry.

Molex connectors can run 11 amps per pin (http://en.wikipedia.org/wiki/Molex_connector).

The gauge of the yellow wire should be 18 and the black wire is about 20 gauge, but I couldn't find a gauging tool at Ace hardware so I'm not sure.

Ok, so Molex specifies 8 amps for 18 AWG, which MIGHT work with 10 miners without catching fire in a properly cooled environment, but you are too close. And since most power supplies use 18 AWG for Molex anyway, you should reconsider the 10-way. Just a friendly warning so that I could later gloat "I told you so" when one of your customer's house burns down :-)

Thanks for the info. Sometimes I run into things full speed before considering everything. I've contacted the buyer and their cables haven't yet arrived so I should be able to sort things out with them before their house burns down.

I am currently building new splitters with larger cables to make sure everything is well within the safe range. I will post some pics once I have them finished and tested.

The 1:10 splitter was probably pushing it with the gauges for that amperage. I'm waiting for the buyer to test them before I decide to make any more.

My 1:1 and 1:2 power adapters are definitely safe and functional. I also have ordered better wiring to make 1:10 (or less) splitters.

PM me if you want to buy any custom cabling with any number of splits.

I've been collecting error messages and solutions in the last section as well.

Thanks!

I couldn't get your batch file to work (looping through all the ACM devices, but I was able to write a batch file that launched the 10 I have in 10 separate screens.

Thoughts:
1) put $count at the end of each screen name. That makes it easier to switch to a specific miner.
2) I also needed to "sudo -s" before I run the batch file, or it does not let me use the devices.
3) instructions when ssh to start the miners, something about "screen -S mining" , and A, D to exit ssh and still keep the miners running.

Now to see if they run all night.

OK Take a look now and let me know if it's more clear.

Also Try:

Quote

If you don't want to run all of the miners as sudo/root

Code:

sudo usermod -G plugdev -a

Where is your username: sudo usermod -G plugdev -a miner

And see if it lets you run the miner as a normal user (It does on my linux and pi)

I should make a section on how to physically label your gridseeds with serial numbers and then run them based on serial numbers so you can see if you have an issue with one? I think.

I think I'll grab a few hundred before you peeps buy them up.

Wonder If they are even saving any space?

Looks like 10mm ish savings at least

This looks really interesting, thanks. A bit pricey for a couple feet of wire, but if it works and doesn't burn the house/shed/datacenter it might be worth it.

Yeah, the non right angle plugs are a lot cheaper

Anyone with more then 1 miner under windows have them dual mining with cpuminer and cgminer. Just making sure what I have working here is right. I have cgmine for the bitcoin and 2 instances of cpuminer different com ports for the scrypt. Thanks

Will do. Actually I'll make it username agnostic.

Did it all under user Miner, and it seemed to install fine. When I run cpuminer, I get the error message:
"./minerd: error while loading shared libraries: libjansson.so.4: cannot open shared object file: no such file or directory"
