Hi guys,  I have a quick question about the sequence of the washers/nut  on the fans in the Terraminer. Basicly from the inside, the fan , what is the next washer? is it the flat one? the plastic one? or the spring looking washer? also from the outside also, before the grill, is there a washer I need to put back on? Any help would be greatly appreciated Smiley

I wish that was so, just the basics of skill/s are physics, network programing expertise, C compiling, EE and EE design software usage, familiarity of semiconductor technology. Soldering and wam-bam is not the case. PCB design is very hard work Sad

If you are just getting started just now on design, looking at over a YEAR in finished product minimum, not considering troubleshoot, manufacture flaws, flashed software and its coding, plus the 2 months minimum of waiting list. Smiley The reason Butterflylabs is having trouble over a year is all of these reasons, plus they took in orders when they did not have a manufacturing system foundation. At the  moment Butterflylabs are having issue with overheating with all of its product and do not know where the issue is coming from no matter what they post publicly. The reason being the 1,500,000 Ghash/s machine is being divided into two machines of 750,000 Ghash/s . This is going to take a very long time they have to physically redesign, manufacture, recode, and re-troubleshoot. The same goes for the smaller ones, again overheat issue cause by reasons they do not know. Which in essence is almost false promises and changed due dates, over n over n over.

The most difficult part is emulation and prototyping which is only designed by an EE, I had to work on the IO system for over 6 months. Chips are easy to obtain compared to where they go and what to do with. There are a few engineering softwares that are capable doing this sort of design, reading the schematics is very important as well as micro soldering. IO system is a whole different story, which required about 3 months of developing. At the moment the hash rate of the four PCB designs total to 130,000 Hash/s yielding with optimum temp and share rate.

ASIC DYI MANUAL & CHIP ORDERS

Recently I have ordered 30,000 more units of chips due to up coming technology trends and have developed PCB's accordingly to specs. I specialize in PCB and semiconductor technology from CA  for Japan semi conductor companies. While in Asia for business I bought 1000 chips that I have had shipped. The design was not difficult yet very time consuming. I have been watching the forums a while now and believe in the btc community. I am willing to share my design specs, parts #s, and at the moment have put together a "how to manual" for step by step instructions. Your first board should take depending on your abilities anywhere from 2-3 weeks. I am planing on selling remaining 750 chips left. I am selling the chips for 1 BTC, which is more than fair. Send me a message for more information or request for manual. This is for serious people who are interested in building their own BTC ASIC miner or interested in resell. PLEASE ONLY SERIOUS INQUIRIES!!!!!!!!!!! Donations are appreciated due to time and effort of over a years intense work and will receive in PDF format the ASIC DYI PCB manual in your email for free.
