GekkoScience BM1384 Project Development Discussion

them pictures... *squeals like a little girl*

If by "on a roll" you mean "several weeks behind ideal projection and frustrated these things didn't work last Thursday", then yes I'm on a roll.

At least the LED works. Some people won't really care if it mines or not so long as the LED works right.

Hell yeah! flashy sticks is all the rage! i cant buy enough of them Blink(1) Mk2 sticks! i want one that can warm my house too! whats this "hashing" you speak of? is that like some sort of robot dance?

Yes, behind. I was hoping to be on TypeZero design by now, and I haven't even gotten working Compac prototypes distributed for testing. Just because I'm not racing other independents doesn't mean it's not a race. I'm also racing new chip generations, and the network as a whole, and my own opinions about how long a thing should take to get done.

about 2 weeks good? yeah 2 weeks.
(i know people Love to wait 2 weeks)

but seriously, don't stress yourself over it, don't cut corners, i don't think people would mind you take a week break from it if it gets to you.

you want to sell this product, and you stay open on whats happening, i think you'll have buyers. i know i would like to buy up 1% (now you said something along the lines of 1000, 1% of that is 10, well i want to buy 10!) of the 1st run, it may not be much, but i think others would be happy to buy more.

ZO RELAXEN UND WATSCHEN DER BLINKENLICHTEN.

I sent some  Burger coin

0.0499 btc = 12.00 usd

don't worry  you will do very well today.

I've succeeded in getting two of four sticks hashing unstably and unreliably but I have seen submitted shares. I can't say for sure what the issue is that gets the chip working haphazardly at about 10% capacity, because the breakout boards were pretty much all-or-nothing. Could be signal integrity issues, I really don't know but I hope that's not the case because if it's a result of PCB layout we got problems. The signal traces are between ground planes - at least they should be if the etch fab didn't get layers out of order.

Nicely done!

btw one of my first surprises was that the USB 5V was rarely exactly 5V ... and depending on the hub - under load it went all the way down to 3.5V. It looks like you're already beyond that with the bolted-down hub, but do double that just in case.
Another thing I had to keep in mind was very short traces to the USB connector - some hubs were very picky about noise there.

And thanks for the pics - keep that pr0n coming!
Did you hand-solder all components? If you did - you are a HERO! I didn't realize how much of a PITA that was until I started using soldering paste and (cheap) stencils. For example - this took me just about 2-3hrs to complete and was significantly less messy and nicer than my other hand-soldered ones.

Nah, you're good - you're still on v0.3 ... it was version 0.5 for me that was the first that sort of worked ... and 0.6 was the first production one
I've been there and I know the pressure and you are definitely ahead of schedule! And it is what it is, and sometimes you have to take a break, step back and take another look, or just give it a day or two break and another solution will most likely appear.

If I hadn't burned about a week and a half on the first regulator design we'd be a lot closer to "on schedule". That stupid thing never worked right, but the prototype for the current version, Novak had me a board etched before the parts arrived and it worked perfectly on the first shot. Stupid cut-up QFN monolithic junk.

I had a week off when I was waiting for the PCBs to come in. Then I jacked with 'em until midnight and worked on 'em all the next day. I did relax the whole weekend though, sat on the couch all Saturday and Sunday reading comics and pretty much didn't leave the house. So now I have to be dilligent and work hard for the next 20 days or so again.

The hub is not the limiter. 5V is driven directly off my bench supply, and it worked fine running a U2 and my crapstack prototype. I built that hub to run half a dozen overclocked USB BEs. The CP2102 enumerates fine.

Stencil? Yeah a stencil would be nice but we've never had stencils for anything. It'd sure be nice. Also, every board we've sold in the last 9 months or so is one that I hand-placed and soldered (I can do about 12 DPS2000 boards start-to-finish in 100 minutes including cook time). We're budgeting an actual pick-and-place and reflow oven for when the Compac moves into production (we need it for other builds, not just miners - yes, we do other things too...). I'll look into that link for cheap stencils, that might come in handy. The ASIC is the only part giving me grief right now with soldering, but since that's the only part that really matters (and also about 20% of the total parts cost) it matters the most by far.

I'm not the hero - I'm sidehack, the hero's hacker sidekick. That's literally what the name means.

SIDEHACK! Shirt, this, now! funding project!

[sidehack]

If you really want to, but I probably won't wear one.

[AJRGale]

just a thought...

could always do a teespring setup.
if no one else is interested, then never mind, no cost to you

Sent some  Burger coin too to bring current to 0.2 BTC and total to 1.5 BTC exactly

0.0501 btc = 12.00 usd

Thanks.

Novak was just commenting, the burger donation is actually not too far away from our actual total budget for the dev so far.

[cavaliersrus]

hey hack loving the updates on the project btw man all those s1's and that powersupply are kicking ass and takin names

[valkir]

And there it is!

100% of the profit will go to Sidehack and Novak!



Go Go Go!

Huh. Nifty. Those printed in the USA?

Yeah suppoce to be printed in the US!  And I taked a good quality shirt. ( a little bit more expensive but not made in china or poor country)

Sorry about that I do not control  the shipping price. I decided to go for 20$ to get a better profit. Its only 5$ per  shirt and we need 20. Go go go

[sidehack]

I'm told $12.50 for shipping. Coulda swore when I looked at that page a couple hours ago it said about $4 for shipping.

USD is too volatile for to be used as a real currency.
