Probably should be thinking about your 1.6TH when BTCguild closes later this month (i.e. June 30th). Maybe you already know about this, but thought I'd mention it anyway.
Sad to see it go.

I just wish I had this now I could do some summer mining even with my 18 cents a kwatt
You do, just not as many as you would like.....
yeah I have
1.6th at btcguild
140 gh at solo pool
this 11gh at mmpool
but summer prices in NJ are just too high to mine.

Maybe the stick miner should be the U4 in homage to the U1 and U2 series? Or maybe the U2+ ?
While I am sure my recollections are off a bit, other than packaging, is this just about what the original BFL ASIC miner was supposed to be? USB powered, and 6-8GH? This is better than a Jalapeno in terms of speed, and maybe 1/10 the power draw?

I'm just sitting here shaking my head in amazement. The next round of miners ought to be crazy efficient. Keep up the reporting. This is good stuff.

hmm so if you can hit freq 200 with .33w/gh with the s5 chip on a special single chip board, wonder if someone can modify/undervolt the s5 to do it?
June 16, 2015, 10:10:42 PM
I am now starting freq 200 setting .
My meter reads 4.89 volts x .75 amps = 3.6675 watts
I seem to be running 11gh this is 0.3334 watts per gh
Hw are low
I added the bridge to give me lots of amps pictures coming
power used is good + < ⅛ clockwise from the blue plus
good numbers 10.93 with 13 errors and 6688 good

and lastly the .61 amp setting does give hw errors but not to many.
i may tweak it to .62 or .63 amps looking for a little less on hw's

Maybe after the USB meter, the next thing to get is a thermal camera module? 
( FLIR reacted to the SEEK by dropping their prices a fair bit.. lower resolution but generally higher quality. )
( FLIR reacted to the SEEK by dropping their prices a fair bit.. lower resolution but generally higher quality. )yeah but the oven temp meter is pretty good. cost = $0
I have also decided to bump amps to 0.61-0.62 vs 0.6
reason is at 0.6 HW is 2% at 0.61-0.62 HW is under 1%
so my stick seems very happy at freq 175 and 0.61-0.62 amps still is that nice 0.31 watt per gh number.
read the thread all answers are here. Does not that seem fair to write.
here is break down
total of 36 watts for the entire setup I don't count the monitor as it is turned off 23 of 24 hours
----------------------------watts
1)pc --------------------23-25
2)usb hub ------------- 4-5
3)fan ------------------- 1
4)usb meter ----------- 1
5)1 stick -------------- 3
The pc runs a full node and uses 23 watts idle 25 watts on a node
A rasp pi would do 10 watts idle and no node. So since I choose a real pc my penalty is 13-15 watts over a rasp pi, cubie, bugle bone etc
I am just waiting for a chance to pop in more sticks to see practical limits for sticks + boards.

A very reasonable argument If it piques your interest anyway, let me know of course it does and I want one. but so many parts with so much gear in house and a very patient wife .
I don't want to add any straws at the moment.
Today the usb meter came an intel cpu came. some fan grills are due. some more parts tomorrow.
I have to build a pc in the next 2 days.
z97 asrock itx mobo
i5 4570t cpu
2 8gb sticks of ram
1 250gb msata
fsp plat 450watt psu
a silent zalman cpu cooler
s much as I would like the meter no more gear for a week or two. (or not and I will say fuck it and ask you for a link to buy the meter)

so was the invalid ones due to power being to low in that btw very neat seeing these numbers from a usb drive .... next question how is the heat on the heatsink ?
with the fan blowing on it no worries. I think I will turn the fan off for an hour. I don't have an infrared gun but I have a temp for food which if placed on the heatsink should give a good number.
27c with fan turned on
40c with fan turned off

went from 27 to 32 c with fan turned off
moved up to 38c
it is hard to read but 39.6c and I played with lowest amp setting here at 0.57 amps = constant hw's
fan drops it down fast to 28c this is in a 25c room temp notice amps at 0.61 this is much better for HW's
lastly look at HW they are at 698

If it's not reporting HW errors during the delay, the "no valid hashes detected" timeout is still based on U3 timings, which the duration is frequency dependent. The U3 would have four times the hashrate at a given frequency (as it has four chips) so cgminer says "well heck, I haven't seen a share in this long it must be hung and needs a hard reset" but that's not really valid for the stick because it's a single-chip device. The "we have a problem" timeout should be four times longer. That'll be taken care of when we have our own driver.
Looking good, Phil. I won't get to play with my meters until probably Thursday. Thanks for getting some good numbers up.

Should be able to get slightly better performance still if the timeouts can be eradicated. Theoretical at 175MHz is 9.625Gh/s, which you're already pretty close to in the average measure

now I had a good meter for 1 stick so I dialed back power the pot is now in this position
+ in stead of ⅛ clock wise the readings dropped from .66 amp to .6 amp
so .66 amp x 4.91 v = 3.24 watts and 9.5 gh
now .6 amp x 4.91 volt = 2.94 watts and 9.5gh hash
or 3.24/9.5 = .341 watts a gh
2.94/9.5 = .309 watts a gh
.309 watts a gh at freq 175 is really good and most likely accurate within 5%
