Topic: The most efficient USB miner (scrypt/SHA) (Read 2003 times)
Amen to that. Good luck to you both.
Admittedly I didn't help much with this design (a bit of concept advise, no technical work at all) but he looped me in on the design and the buck's satisfactorily overbuilt. Should be a fun stick to try to catch on fire.
And I have to admit that this project would have never been off the ground if it was not from the inspiration from your awesome work! Hopefully our work can continue by both Bitcoin/Litecoin communities so we can be less reliant on asian hardware manufacturers
Nowadays I mine 800...900 satoshi per day.
For the fun it is enough (lol)
if someone is interested to co-mine with me ...he is welcome.

I just finished my prototype for a scrypt based USB miner which I'm ramping up for production and will be shipping very soon (hopefully be end of month). Its definitely the most efficient scrypt usb miner made so far, and even beats out the titan for scrypt efficiency. Last test I just did I hit 4.4 watts/MH.

The Compac has been tested to work (enumerating as a U3) on an R1, if I'm remembering right. A Compac2 with 1385 would require specific software so not backward-compatible. I didn't think about trying that angle with Bitmain though.
I am more optimistic about Innosilicon selling chips, but since they thus far have no interest in small quantities or samples it seems getting anything even for testing is months away which puts production more months away.
Also, all this should probably be discussed in a dev thread rather than threadjacking this guy's question.

If by "sizeable amount" you mean "more than zero" nope, I have not gotten a sizeable amount of anything from anyone since the BM1384 purchase end of June.
40GH would probably take more than 2A of 5V. Probably take 2.5V at that point, since the chip would be drawing 10.5W by itself plus conversion losses and controls. I'd estimate 12W into the stick at 40GH, which my base Compac design will handle.
I could buy an S7 and part it out, but the chips would then cost a little over three times what I paid for my BM1384 stock. End cost for the stick would be more like $30-35 than $25 and it'd take about seven S7 to prototype and run out a full 1000-stick batch. Technically possible but probably stupid.

Sounds like a expensive R/D if you have to use the unit itself. I keep hoping someone will release a chip and make competition and they will sell you a batch.
I think it might be a while but I think Innosilicon is a likely one to sell chips, unless BW and LKETC take all they can produce. Would be nice of BM to sell them to you. You should push you can help them sell R1's if they sell chips to you and make your product supported on it. Can't imagine anyone not wanting one if for 25 or a tad more you could push 25 to 40 GH of extra hash from R1.
Keep up the work side!! Got a few people at work that are going to buy a few of the USB miners with me 
.
Have my first one running 2 days now.
It seems I could clock these up to like 20GH/s if I cooled it well.

About 10 stock up to about 50 if you're really pushing it. 20-25GH should be doable with a 1A port.
I am mining with an antminer U2
I am not sure if 80 years will be enough to ROI...
and I do not count electricity cost.
And i'm be serious saying this.

u2 = 2gh
with 0 power cost it should earn about 1.50 usd by the end of 2016
sidehack stick = 13.5 gh
with no power cost it should earn about 9 usd by the end of 2016
I'm closer at 1.5gh
should I overclock, without fan?
A u2 can do freq 225 but will need a fan
Sidehacks sticks can do freq 400 but will need a fan
The u2 is hotter the sidehacks stick so if you oc use a fan.

I got tips from the others you may try avalon 4.1 with low power cost... Usb for now is not profitable ur you wait for a long time...
I am wondering what the most efficient USB miner is?
Thinking of plugging some into my work computer... heheheh

this one is but it only works with Sha type coins.

And look here for a list of now and then stick miners

You will need to have decent power, most use a powered hub to get this. Also use a Y-USB connetor ( http://www.ebay.com/itm/221661361513?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT ) Allows twice the power as 1 usb cord would.
Use the compac-cgminer and it's pretty simple from there. I would suggest a little fan if you are doing this to push air.
For most people, the S7 has about the same odds of turning positive as a stickminer does.
are the usb miners still profitable or are they more just for fun these days?
The USB miners will be mining in the positive, however the odds are low you would see an ROI.
IMO they are the PERFECT! PERFECT, miner for a hobby miner / lottery miner.
Get the S7 if you want ROI, IMO.
