Hi guys,

This may be in the wrong section so mods please move it if needed

Basically I have a d-link h7 powered USB hub and want to join two ports into one so I can crank up the gekko stick I got free when I bought a u3 on eBay.

But I would prefer not to use a cable as I want to keep it as secure as possible and "airborne" so it gets plenty of airflow from a nearby Arctic breeze fan.

So does anyone know if there is such a pcb with two male ports going to a single female, or does anyone know how I can make one? Bare in mind my soldering skills are basic  

Or if anyone can make me one to suit my needs id be great full and willing to slide over some btc. I'm in the U.K by the way.

Thanks everyone.

Damn! There's me thinking my lame horse would progress through the pack. Now it looks like it'll be dropping back 

citronick is offline, if my R1 pulls its finger out I might be able to jump into fourth 

Bitminter has a minimum payout of 0.01 but your earnings will accumulate and the minimum will auto payout once the minimum is reached. I started there with 3xU2 sticks and the dust payments just sat there and accumulated.

You;ll need to rent/hire a forklift to move them 

Well just a little update for information purposes. Bought a usb oled monitor thingy (basically a screen with a read out of Volt,Amps,Watts) how accurate it is I don't know but seemed about right.

The U3's I have, one pulled 0.00A through the usb at 4.85v. The other pulled 0.05A at the same voltage. The gekko was pulling 5.2watts, 4.87v and 1.16A. I turned the voltage down on the stick and have kept it running at 235mhz for now. Since ive turned it down ive gained 0.6Ghs 

Some may find the info about the U3's useful 

They going to be alright all running from one socket?

That's what I thought about the U3's seeing as they are externally powered they must draw a very small amount. Not sure how to check that on the U3 Pcb, I'll take a look tomorrow.

I got the multimeter out and it's running 680-690mv so pretty good on the voltage/ghs aspect I assume.

I'll grab a y cable and see what happens with a bit of fiddling. I'm not complaining at all about the stick though (incase its come across that way). It's works great and constantly gets the highest share on cgminer, most of the time beating my s3's lol. I just like tinkering and can never leave anything alone in its standard form for long lol.

Thanks for the help as always.

That's what I thought. Cant figure it out. The gecko is running 235mhz on cgminer on the powered hub no problem, but couldn't get the U3's or gecko to run through the R1, so now the R1 is just a slave to the gecko and cooling it down.

If I had the know how to open it up and tweak the various doohickeys inside I would, but my heavy hand would probably mangle something or do something which would make it pop when it was fired up lol

Switch back and join the fun make things more interesting

Got it set at around 0.6-0.7 I think (will get a multimeter on the connections soon). Its getting about 12-13ghs at 230mhz. Im only running the one stick along with the 2 U3's on the same hub so don't think im pushing it too far. Would a "y" cable help with the power aspect, by spreading it across 2 ports?

Nice on thanks cowboy. Ill give it a go once I get a Pi. Its the more indepth setting up of it im concerned about aswell. Like getting it to restart by itself if it encounters a problem. Plus getting the .bat file information across correctly as its running well at the moment.

This raspi stuff is a bit out of my comfort zone but im willing to learn, just don't want to end up screwing it up and having an expensive paperweight (albeit a good looking cirecuit board) lol

So im running cgminer 4.9.2 (gecko edition) on my laptop and im running a 7 port usb 2.0 powered hub (2.5amp) with my gekko and 2xU3's plugged in. Just out of curiosity I tried turning the freq up on the gekko to see what I could get. Managed to get it upto 230mhz which is now stable. I tried getting it upto 250mhz but even with the voltage turned right up it wouldn't have it.

Now my question is; is the hub the limiting factor in this?

Thanks.

p.s. I bought a USB 2.0 hub as I was planning on running my "usb miners" on a raspi sometime in the future.

Thanks for the help as always

The difficulty of the miner doesn't really go with the difficulty of the block. As far as ive read the difficulty set for the miners is based on the hashrate. The more hashrate you have the higher the difficulty is for that miner. Its so the pool doesn't get overwhelmed with shares that are pretty much useless. Basically kind of like traffic control. It doesn't stop the miner achieving the difficulty of a block (ie. 167G) but it stops high hashrate miners submitting loads of smaller shares that are no where near the target diff. I think I read somewhere that the target is 12shares a second.

That's just my basic understanding of it. Someone with a lot more knowledge about it will be along soon to give a more detailed explanation.

For example my 2xS3+'s are under the same worker name on the pool im with and both have a diff of 512. Whereas my 2xU3's and gekko stick are running on cgminer and have a diff of 64.

Good luck to you too

Best share ive got so far was 8G on my S3+. Best share on my cgminer with the U3's and gecko was 195M so they are close. Just wish I knew which of the ones on cgminer got that close lol. Its frustrating not being able to expand the window any larger or be able to scroll up and down the shares list.

On a different note, can someone crack this block please. I don't want to have to crack out the red boxers again, they just aren't my colour 

Yep power is free (for now). So aslong as she earns her keep so to speak then that's fine with me

Ever since I ran a Gekko stick on mine its not been happy running anything more than 131mhz. Anything more than that and it restarts constantly. So now it just runs a fan for the gecko stick that's in a hub with my U3's running on cgminer through the laptop. Id like to get the R1 to run more but haven't got the foggiest how to get more power to it.

Got any pictures? As they speak a thousand words for un-computer types like myself 

Well that's just confirmed it completely then. Just wish there were more of them about really if they are that good.

That being said how much is one worth in GBP?

Kanos firmware update basically makes the antminers run smoother and quicker. They don't affect the hashrate but the giu loads quicker, you have a couple of extra options within the menus etc.

The S3 update can be found here:-

Ive got it running on both my S3+'s with no problems at all.
