I agree I would like to see some more results on this resistor. Post up if you get any good data on those. All air cooled I think that's my final step before I start selling a miner or two. These are slowly becoming ever less profitable.

On that thought Alpha-t.net the first scrypt asic soon to be on the market. Batch 1 preorders are closed, but I'm seeing them being a lot better than BFL ever was.

And just got blown out of a close second in referrals after dude came in moving 52 coins at a time can't contest that. Only other thought before you go live add a pic to the tab bar in the browser. looks good though, all the luck on your journey.

2 things you might want to think about adding is how much the current wager is for and if your opponent is a bot in the game. Seeing the outcome of the game for a few seconds would be nice before it flashes the congrats or sorry message as well.

I'm not complaining but some people took this to a new level. I was pulling decent leads on everyone in 4 categories. Then you got the guy who apparently has a little to much free time doing 1300 BTC between 2 accounts. This just made it less fun as the 20 testnet coins I have been waiting to deposit for 3 days finally arrived. That pace isn't even worth catching up to, but challenge accepted as I'm not inclined to just let another win. If I come out of this with nothing I'm gunna freak a little.

On a side note we drained over 1000 coins in under a week and i'm pretty sure it's lagging like a bitch as some deposits are not even showing.

exhibit B: 4 chip jalapeno 2 installed by lightfoot with heatsinks on 2 power FETs,1 gate driver(copper)

http://i.imgur.com/fYexzqJ.jpg

hmm. this image does not bode well for upgrading my jally. my board is different(?). there are 6 MOSFETS under the 2 bigger copper heatsinks shown on the above image (not two as quoted above) on mine. and 6 more along another side.

mine is a very early jally, board says BitFORCE SC rev C.

I think you might be overreacting as even though you can't see it there are 6 fets under those two sinks. Every board i have seen or heard of have 6 in on corner and another 6 in the other corner. The difference is the "Hot mosfet" design where they're all the same size. I'm assuming he's summing up the sink count. Also all of my boards including the blackfriday special are rev. c just my observations.

lightfoot

maybe its in the thread but I missed it.. but..

how do you preheat the bottom of the board?

I get the rework station on low air and a set temp for so long on the top of the chip but what do you use to preheat it? toaster oven ?? Wink

If you don't want to buy a specialized pre heater, an electric skillet works great. Something that can get up to 400F. Make sure it's not placed directly on it, prop it up on some screws or what ever you deem suitable. It may not be necessary but it has given me nothing but 100% success putting chips on. Good luck bud, and remember the flux.

You want to preheat the board to prevent flexing cracking large temp differences that break things. Warping or breaking your board would probably ruin your day.

The above is something to think about. The only other concern with mineral oil is that if any components are cheap rubber it will slowly dissolve them. This was my main fear before I realized all the capacitors seem to be a metal case. It seems like just the USB and power wires might pose to be a problem.

As for circulation and heat dissipation, you literally put the electronics in a tank and have a pump moving the oil through a radiator. It's almost exactly like water cooling but if you have a leak it doesn't fry your shit.  There is like a 0.01% loss of oil if it's mostly contained. ie if it condenses on a hose or wire and drips down = loss. 

All this effort only concerns me with the hashrate changing so quickly. What will it be like in a year? Either way I have enjoyed the hell out of this thread, everything I got to contribute, and of course the various help from community members. Great job everyone who's been here.

Thanks I've sent him a message.

Additional:

On the cooling front, I'm resurrecting an old freon unit I used on an overclocked quad board 10 or so years ago.




+1 if it can be done it should, good luck man and make sure you let us all know how it goes.  The only other option I researched at the beginning was mineral oil but cost out weighed air by a bit.

Hope you're starting to see some of that volume move up, hopefully see this in the future as well.  Wink

Surprising enough it adds up quick that little fee. If people start bringing in their own coin this could be another primo thing.

^^ Dude chill it isn't your baby.  Live fire fragging is some of the best testing. I got in on that faucet before, after that told them and helped to fix it. If it's possible to exploit, someone will inevitably. So stop crying you didn't have the "good" idea. Like the guy who camps in a FPS gets a 2.0 k/d, don't be mad he owned you, the game can be played many ways.

In transaction history when you withdraw it comes up as undefined. Everything else seems to be working fine as of now. Good job.

Just a heads up for bugs, I couldn't create a game. Nvm still can't "You cannot create a game right now because you already have one in progress."  The game of hi or lo just before froze so I refreshed the firefox window. When I say froze it was loading next round for a few minutes. Browser and everything is up to date. Also I shall be playing for a prize......

Update yes I'm sticking to RPS as the hi or lo seems to keep bugging out and freezing on me. Firefox browser with java and flash enabled and up to date.

I have a problem with my unit, I use an AVR ONE ti can't read the device like you can see on the screenshot

This is why literally EVERYONE said "Just get a dragon it's only $50.". I don't know how much other programmers work but that's why you read before you click. This also isn't the correct thread for this, there are a few other flashing threads. Go read through the 40+ pages of info, it's a plethora of knowledge. Also make sure you have the 256kb chip and not the 128kb, this literally makes all the difference.

Heads up I get a 404 err code when I access my original account. As for the duplicate faucet and game info down below was a problem too. Firefox browser, but I haven't played in a few days as no one else has been either.

And in the really interesting news, I had a unit come in with a power supply that went *bad*. Jalapeno, ran it with 3 chips, checked in and saw that it had a massive amount of errors going on. Shut it down, put it on the bench supply, worked fine. Tested the power supply and I see 60 volts between negative and AC neutral.

Glad I have an isolated power supply on my miner. I'm wondering: Does BFL want the old power supply back when they RMA, or will they just send a new one out? I would really like to "interrogate" this one and see if it has the same blown caps as the one from England.

Good news: No damage to the jalapeno. In fact it's now hashing at 14gh with a second added (client provided) chip, much better than the 5.4 it came in with (it has two lousy chips on it and two very good ones).

C
I've heard both... apparently the right and left hands aren't talking... so maybe it depends on if you are wearing matching socks and Mars is in the shadow of Venus...

I honestly can't see them needing the PSU back, it's not like you could fix it and reship it.

^^^ Yes, Thank you.

Could you please clarify 0.05 screen and 0.045 balls? You don't mean 0.5mm screen and 0.45 balls? If what you said originally is correct I can seem to find the supplies on eBay. Congrats on the water cooling!!! Kinda thinking, I didn't go this way but on eBay they have water blocks for like 10-15$ Hook um all up with a pump and a big enough rad and that's pretty tits. Just an idea as I know those self contained units arn't cheap on their own.  Check out the water cooling they did with the 60 Ghs models.

FYI I have 8 12v rails 25A, 2 jalapenos a piece. My custom 16 gauge wires are a little warm on the 2 jalapenos 1x6 chips 1x4 chips. The 18 gauge wires from the power supply are actually warm-hot to the touch. The insulation isn't melting yet but I think I need to pull the weak link out.  6 chips still running magical under 60c on air..........

You blew up U15 as well? Hm, interesting; wonder why that is failing.

I think that is the 3.3 volt supply line, if you want to send it over I can take a look at it. I'm sure though they will honor the RMA. Drug, did swapping that chip fix it?

C


I wish I could say yes. I believe when I originally replaced it just powered up for a second. It blew again or something else when a real PSU was used. I think I pulled a pad off when removing it a second time. So I removed the chips and will list on eBay as a dead jallie soon..... Sorry

Radiator in the barrel maybe not, outside better idea. Mine currently heat my apartment, only a 1 bedroom but still. Water cooling is amazing because it works in any orientation. I wasn't aware you're using one of those self contained units. I'm not a huge fan but I have owned one, they're extremely simple to use. Never worry about adding coolant or bleeding the system proper, as for actual life mine was fine for the year I owned it. The only reason I wish I was 100% water cooled is the 10 fans running for my miners. Do a google search and you can find what I assume is the water system they used in the minirigs. A lot more coverage, kinda wished this was an aftermarket option.

Another unit up to 20gh. To minimize heat near the FTDi chip and the FETs I have been placing 5 chips as follows:

2,3,4,7,5 (use the map in the previous pages for locations). 60c temp with stock heat sink and a very warm power supply. Wish I had my darn PCIx cable from BFL....

Otherwise seems to work well. Tomorrow I should be having 4 more chips come in and the water cooler, we'll try for 7 on one jally with water cooling...




I believe you've seen the molex to barrel adapter that takes 5 minutes to make. It's a lot safer power if you have the PSU for it. Yellow 12V line to the inside shielded wire, and the two center grounds on the molex to the outside braided ground.  I wired up 4 of these just to get my miners up while waiting on cablez. Not that he took long, 2 days maybe on his end and an amazing looking product!! 

So in the end you're going to hit 8 chips right? Have we thought about cooling the FTDI chip with a simple sink? If you need any help with water cooling let me know, I love the stuff. I didn't go that route because of ROI. Just be super careful if you drill into the water block not to permeate the chamber. Don't mix metals between sinks and radiators ETC. ionization will happen and slowly deteriorate everything. It's usually suggested to run the system for hours to leak test. The thermal conductivity of water exceeds air something like 10x so this makes me giddy.  Air vs water let my processor go from 4.0 Ghz to 5.2 Ghz in the end it is usually efficient enough that the next hindrance is hardware related as there should be plenty of overhead for heat.
