Customs problems, i need a invoice from friedcat and no answer on the email/qq. My prismas are at customs.

I have to say thank you AM for the amazing products and support...simply the best!

I am seeing about doing a run of the USB adapters. I will get it all set in a day or two and let you know prices and such.
Hopefully we can get these in more peoples hands.
They are harder to get a hold of than FiedCat right now. LOL

Hey, that's great, thank you! Now to see if I have any of those laying around, I have a feeling though that I don't. But CP2102s should be easy to find I think.

or has anyone tried using a regular USB to UART adapter?
One user modified an old Block Erupter USB (those small things that plug straight into a USB port) to work with a Block Erupter Prisma;[DIY] Tube/Prisma USB Adapter from USB Blockerupter
He notes:
You should theoretically be able to use any CP2102 USB-UART witha 1K pullup resistor from 3.3V to RXD in this fashion.

No kidding, I've sent emails and PMs to Friedcat and Phasebird, no luck. Sorry to hear about your popping cap (haha, we're Bitcoin gangstas, popping caps in the process of obtaining hash). I wonder if the proximity to the fan controller contributed? Maybe there's a short near the fan socket, or the potential for bridging between the the fan power and a trace that runs to that cap?
As far as the CP2102 goes, I think I have an old Sparkfun USB/serial adapter, but I have to find it:
https://www.sparkfun.com/products/retired/8531
Unfortunately, now all of their USB to serial devices use FTDI chips, which although should work, won't be detected by cgminer.
I'd be interested in following your progress on this! We've done a few (non-Bitcoin) board runs for various prototypes, and looking at this USB adapter it shouldn't be too difficult to mimic the functionality. I was just hoping to have everything hashing stably without having to wait for a custom PCB, parts, and then assembling it. You know, the expectation was kinda sorta that these would work...in October. But, AM became a preorder scam company apparently, and my main priority is salvaging some of my investment in their hardware, and being glad I don't own shares.

So has anyone actually gotten these to work on a standard Linux machine yet? I keep getting the "Unexpected value 00 received" error. I've tried different git branches suggested in previous posts. I've re-cabled this in various ways also with no success.
I have a Pi somewhere I will try to repurpose for this if that is what it takes.

Try their cgminer branch which got updated recently.
https://github.com/blockerupter/cgminer
If this doesn't affect hash rate(around 350GH/s per board), just ignore this kind of error. I got several boards with occasional errors like this, yet all works well.
Thanks, I downloaded that branch again and tried it, but same issue. I never get any hashing and I've even tried each board individually.
Most likely a bad USB adapter..pretty common. I had the exact same issue and sold my Prisma off to someone with a BE Controller, and it worked for him. If you do not have another controller you need to find one or sell that crap miner off.
Has anyone had any success at getting additional USB adapters? I've sent emails to Phasebird, and PMs here, but no support whatsoever. It's like ASICMiner went bankrupt over the past month and entirely disappeared off the face of the earth.
We have really late miners here, and we really need support. That, or has anyone tried using a regular USB to UART adapter? I see the Prisma ones are 3 PINs, are these specific serial or I2C pins that we could use another device to talk to the miner over? I haven't looked closely to see if they have a visible USB FTDI (or knockoff) chip on it, but if so it'd at least be a step in the right direction.

Sorry my updates are not more forthcoming I'm a little burnt (ha) from troubleshooting these:
I had just fired it up from an off state, where it had previously ran for about a week now, fire started about 10 seconds in. Thank god I was there, I saw flame like a candle and was able to pull power immediately.
Just so you know it is very cold in my mining rooms right now, ~50-60F or even colder at nights. My cointerra is my most heat sensitive miner and it is running cool and stable.
Out of 8 prismas, or 32 boards:
4 have transistors that climb to 80C+ whereas all other boards exhibit 30-60C. They will sometimes still hash, but slowly, and the tube heatsink is really that much hotter because of it. Burning hot. And some of these only exhibit the problem on half of the hashing board.
8 have power down / hashing issues. Suspecting bad chips on these boards. They hash, albeit slowly and reset and generally I am blaming these boards for breaking the daisy chain and causing the others to have problems.
1 has burnt out on me now
I'm not trying to smear asicminer and have no agenda. I am disappointed with these problems. I had some plans that were in holding pattern waiting for the all clear and now they need some rewriting.
I would be happy if someone from asicminer would just offer me replacement of the bad boards. I've lost downtime but it will be more loss without any hashes. Overall this was more of a test run to see if it was worthy to order in bulk. The ones that do run, run well.

Oh.., it's not a joke. Never would have thought that it's possible with AM hardware. It's a great luck you were there at that time

I had a board go out on a tube.
I contacted support and they told me to ship it back and they'd replace it.
My experience with AM support has been pretty amazing.
WOW, I have 4 bad boards I have emailed sales@, PM'd, etc.. NOTHING! Not to mention OH JOY I get to pay $100+ to ship back garbage that should have been bench tested. GR8 sales support right, right, sure, sure.. BS half-a$$ @ best and the hardware is junk.
You are not a shareholder.

I sold my Prisma 1.4T. Thanks for all the help. If you use a Prisma, please build a case for it out of metal rods and screen material to be safe. Also, you can bend the metal on the bottom of the unit to lift it up a bit.

I posted a photo in another thread and can post more if need be. I'll accept 1 BTC if someone wants it. PM me if you are interested. 3 of the 4 boards work individually and would probably work together with a controller.
November 16, 2014, 10:21:25 PM
1btc would be fair if the boards worked. Used prices are about 1.1-1.25, knock it down to 1 for the cap being fixed and we are on track. 1btc with boards that won't work together at the expected hashrate and a board that may or may not work once the cap is replaced and it's just not worth the risk. I'm just sitting back and waiting for the pics from when he goes Office Space on it.
November 16, 2014, 09:15:21 PM
I'm willing to sell my Prisma at a discount if anyone wants one with a missing capacitor that I couldn't get to hash more than one board at a time... It has the USB dongle and not the controller...
I would take a chance on it for .6 btc
I think that's a bit low.
photos? 1BTC would be fair if theres a chance of fixing it or at least running 3/4 boards

the lines above explain it in a round about way
... you have to install new rasp barry OS above they give you a link then do it or i guess you can use WinSCP and delete it if you use windows and then put his version in there . I'm Gonna try both ways to see . and there is another way i saw Nwool and CK explained the other day in some posts i read some place but didn't pay it any mind.
Raspbian you can get it here:
http://downloads.raspberrypi.org/raspbian_latest
Simply download and put it in your SD card (there are tons of guide to do this, google it).
When you have your system ready, ssh into it and install Minera
Skip this step and continue below if you have a web server with PHP just installed.
sudo apt-get install -y lighttpd php5-cgi
sudo lighty-enable-mod fastcgi
sudo lighty-enable-mod fastcgi-php
sudo service lighttpd force-reload
When your web server is ready you can install Minera:
sudo apt-get install -y redis-server git screen php5-cli php5-curl
cd /var/www
sudo git clone https://github.com/crazybitcoinguy/minera
cd minera
sudo ./install_minera.sh
.

Tried following those instructions but no results. If someone would be willing to provide a direct link to Crazy Guys Rasp Pi image I'd be happy to toss you some coin. Bout to give up on this POS and put it on the market. I've attempted to message him directly but I guess he is busy.
When do I type this?
sudo apt-get install -y redis-server git screen php5-cli php5-curl
cd /var/www
sudo git clone https://github.com/crazybitcoinguy/minera
cd minera
sudo ./install_minera.sh
when the Rasp Pi first starts up in the command screen or whatever its called?
So I tried type this in and got to this line
sudo git clone https://github.com/crazybitcoinguy/minera
It says 'destination path 'minera' already exists and is not an empty directory'
I skipped that line and went to cd minera and it did something that time.
sudo apt-get install -y redis-server git screen php5-cli php5-curl
cd /var/www
sudo git clone https://github.com/crazybitcoinguy/minera

Why not try the sales@bitquan route and see what they'll do for you before you give it away?
