I managed to give a blade artificial breathing . pictures of Frankenblade soon.


anxious await pics of frankenblade!

and any others of your creations, would be very helpful.

Just a question. I have 2 blades (4 boards) running at 838mhz. It's a good problem to have but they are only drawing about 200 watts total (~50w per board) at the wall... doesn't that seem low? The hashrate at the pool is ~11.2mh.

my blade draw about that with seasonic psu .. measure at wall on killerwatt probably morelso 110 for the blade before killed it

You might consider adding a ferrite core on the supply wires if you opt with using resistors on the board. Just bridging with solder could add a considerable amount of inductance, and causing EM noise problems down the road, and I believe that to be a bad idea. This may not present as a failed blade, and may instead just limit your ability to ramp up the proc frequency because of HW errors due to unstable supply.

Not to disagree at all, though familiar with ferrite cores had not even heard of ferrite beads before modifying the 5 chip miners, but will just point out that some of the later blades did ship with 0 ohm resistors in place of the anal beads.

Are there any merge minable scrypt (or scrypt-n for that matter now) secondary coins that actually trade on any of the exchanges that WP uses?  

Poolwaffle, I don't remember seeing this mentioned ever, seems like if answer to above is yes, it may be a good feature to have to eek out a bit of extra profit and set WP apart from the other profit switching pools.  I don't know of any decent profit switching pool that is currently at least publicly doing this.

Is the feature to keep certain mined coins still planned or was that a non-starter?

Not familiar with that pool and how they payout but yes in theory you'd need 3 wallets if you wanted to earn/receive all 3 coins.   This is how it works on simplevert.

Sir, I believe that is a ferrite bead.   I am far far from expert on this type of thing and I am basing that only on the label on the board but believe that is what it is.     What makes you think that particular component is bad?  If it is just because it is a short I think that is expected unless I am mistaken.  HTH.



I have a short in one of my blade halves that I have no idea how to even begin to figure out, when I put my meter between any - and + of the 12v (for instance the power plug, or anywhere) my meter (autoranging ) immediately jumps to 0.000XX ohms like a dead short then quickly goes to about 0.58 kOhm and settles there.  

I added a heatsink a week ago to the back of the board (of course with epoxy...bleh) and after that when powering it with that stupid barrell conector gridseed loves I heard the unmistakable bzzt like there was a short so I immediately unplugged and the above is what I've found with the meter.  Its been dead since as I didn't think powering it would be wise and I don't know where to begin looking.

The way the meter behaves seems different than say touching the leads together or putting the leads across a known value resistor (or one of the beads even)  thinking it may be indicative of something.  Could be my imagination and inexperience though , but it is not a dead short...


Any idea on mine?  Where to even start looking?
