It was you that specifically mentioned you have problems with exactly resistors and capacitors. Shifting goalposts. However now the new components you seem to be saying you are building your own power supplies or DC-AC-DC switching voltage regulator units from scratch. How else would you need mosfets and rare inductors?
I would consider designing and building your own power supply units or switching regulators to be highly silly. Mosfets seem odd to me as well... Apparently they wanted to go with ATX power supplies, so I would expect 12V to run to each board, and a high-amp low voltage regulator (which should have one inductor and some caps) with very thick PCB tracks to carry this to their metric shit ton of low spec chips (each with more caps). If this 3 board design is real, that means 3 inductors per unit. If they really want to put mosfets in to control the power, put them on the 12V side and you can again use just 3 per unit (or have regulators with enable and it's 0 per unit). 900 mosfets and 900 inductors should not be difficult to acquire. The regulators would be a bit harder, but he didn't mention regulators. (But that's a common theme - who knows what to believe until someone actually gets a unit). |

Maybe I wasn't being clear, Mosfets and Inductor is what I'm most worried about
Not being clear? Is that the new name for lying by omission? Do you guys really think you're better than BFL? |

see this shit? I don't post anything, people bitch. I post actual problems, people think I'm lying. I applaud you not to order from us ab8989.
What I see is you looking for examples that agree with this claim while ignoring examples that do not. |

A) Designed an exceptionally inferior product
B) Purchased said product
C) No one has received said product
D) No one has received a tracking number
E) No one has received the product for review, even a test unit
Basically, you have paid for the same service you are bitching about BFL for, but you've paid for an inferior product. Yeah, and I'm emotionally invested. Actually you are describing BFL.No, that doesn't really fit well at all. A) BFL wins on power usage (and therefore longterm profitability) hands down. B) Only this fits C, D and E) The difference here is that Avalon claims to have shipped, but somehow has no tracking numbers. They also could have delivered to local customers already...but have not. BFL is claiming to have not shipped. |

Complete opposite, We did some time tables and realized our greatest time waster was us smashing trolls There's a difference between "smashing trolls" and "keeping your customers informed". It is insulting to your customers to say that you kept them in the dark simply because trolls exist. |

Yours at least has a phone inside, and theirs is empty  Why do people think the Nexus 7 is a phone? |

The optimal package for bitcoin hasher would be something like TO-220 with 7 leads: http://www.psitechnologies.com/products/todo220.phpThe I/O would be serial, the leads would be VccI/O ClkI/O RxD TxD VccHash ClkHash and Reset. Ground would be provided by the heatsink screw pad. One could even omit reset lead by doing serial reset: hold RxD high over (say) 100 I/O clocks. Well, from the choice of packages (all with many more pins) one can surmise that none of the Bitcoin ASIC vendors obtained the advice from the power-analog and mixed-signal designers. Chip Specification
Technology Summary:
TSMC 0.11- micron G process
5 Metal
Core Voltage: 1.2 V
I/O Voltage: 3.3 V
Core Frequency: 256+ MHz
Number of Pads: 48
8 Data
40+1 Power
Package Type: QFN48 -0.5 Pitch
Packaged Chip Size: 7 mm x 7 mm
Chip Interface
Data Pins (8 in total):
Clock i
Serial Data In [2] i
Serial Data Out [2] o
Serial Data Bypass [2] o
Reserved [1] - Having extra pads for power kinda makes sense, but I wonder why they have dual I/O lines. |

All their messages are in favor of BFL. 100 percent.
Typically they are anti-BFL-hater, not pro-BFL. |

all of a sudden 25% less chips.
All of a sudden? They clarified weeks ago that 75k would easily cover all their pre orders. |
|
|

lol, I guess this idea is shot down now since btcfpga will not be delivering products at all.
He's hosting devices from any manufacturer. |

Are you charged at more than 25cents per KWh?
Yes, but I don't think you understand my point... |

The BFL thread has gone mostly silent since Avalon started the process of shipping.
To date, Avalon has released about as much evidence of shipping as BFL. Weren't they going to ask their customers what shipping method they wanted? What happened to that? Why do the recipients of the first two units still not have tracking numbers? I'm not saying they haven't shipped, but you shouldn't treat what Avalon says as gospel any more than what BFL says. It just shows a blatant bias. |

What you leave out is what that span of time actually is. Some estimates are 2.5 years for an Avalon unit at a specific rate of rising difficulty. A BFL Single SC may become unprofitable in 3 years. So you gain about 6 months...maybe slightly longer.
Wow. You think a four (being generous here, could be 6) fold difference in power usage only means a 20% difference in how long it's profitable? |

Doesn't having the tracking number give you access to the recipients address? Perhaps it's for privacy.
Usually not, but most posters would be quite happy with the recipients of the initial 2 units saying "I've got a tracking number and it's currently at X". |

ok this is it, I am now certain that nathanrees19 is somehow affiliated with BFL, probably even Josh himself.
Why? My posts probably seem out of context, but the site that was linked earlier (which Micon apparently set up in attempt to humiliate Josh - wtf?) previously had pictures of two males (one of them presumably Josh) and text which indicated that they were in a homosexual relationship. This kind of behaviour reeks of homophobia and a whole host of other things that don't need repeating, although I might mention delusional: isn't your sock-puppet function to troll up the Avalon thread?
How could this guy criticise me? I am the great BRYAN MICON! He must be a sock puppet. When someone like that is stinking up a thread that's already a trollfest, it doesn't take someone who is "affiliated" with BFL to call him out on his disturbing behaviour. |

What happens if one of those unreleased features makes them an non-competitive lemon? You're going out on a very long limb here if you think they have a hidden feature that can negate the dramatic difference in power costs. |

Because people would still be willing to pay more once they know what it is they are getting.
Okay, say I want to buy a device for mining, and I want it to remain profitable for at least a year. That means I am looking for a device with the following features: Sure, Avalon could have some extra awesome feature, but unless that feature increases mining (maybe it sees the future so it knows which nonce it will be without hashing?) or reduced power (maybe it includes 16 100W solar panels to keep the unit online for free?) then the unit is not going to be superior than a boring competing unit which does the same mining for 1/4 of the power. Quoted for future reference. A sampling of a BFL supporter before the review.  I 'll ask you later on if you are still thinking along the same lines. (Don't worry, I know it won't make sense to you until later.) Well, that was rather predictable. |

ever heard of undervolting?
Yep. Dynamic voltage/clock adjustment would be a useful feature, but it's not likely to push the efficiency up very much. |

Really?
Let me point out two major issues here:
1. Announced BFL power consumtion may turn out to be not like advertised
Let's say it blows out by four times. 240W is still much less than 400W. 2. While you wait for your BFL product even eith 100W power consumtion (I do not know actualy what is advertised) your roi may become even a years. Menwhile first and second batch of customers will enjoy their products and make some good money asuming that BFL will add some more delay There is no doubt that first-batch Avalon customers will make some quick BTC (if they ever get the whole lot out the door), but the second batch could easily ship later than BFL. |
