Well...I would definitely say DON'T try it on your gridseed until you've had plenty of practice with another circuit board with tiny components first.  To put it in perspective....the 0402 resistor on the gridseeds is about the size of the leg of an ant....or a large piece of sand.  

A hot air station makes things easier because then you can just use tweezers to pull the part off and replace it, but most hot air stations cost more than the gridseeds do now.

I used a standard cheap 30watt iron with a very fine tip.  A hot air station would definately be better, but it can be done with an iron if you're careful enough and have had practice.
I didn't use a solder sucker, I used solder wick, but really I didn't need to use it hardly at all because I didn't make a big mess while doing the mod.

Radioshack should have everything you need for a competitive price.  Some of their stuff (like individual components) is priced a little high, but the iron's, flux, solder, wick, etc. should all be relatively inexpensive.  I think they have a 25watt iron for like $14.  I know they have a $14 DE-soldering iron which I've seen some methods to convert it to a hot air iron by removing the bulb, and placing steel/copper wool inside the tube and attaching a small aquarium air pump to where the bulb was.  Might work, might not.  I haven't tried it myself.

Do they only pay out after full confirmations?

I've already pulled the autotune results out of the log file and have no quarrels with doing so, however my suggestion was for dumping to a json config file so it's ready to go - no further 'intervention' needed.  Much like cgminer/bfgminer, it could write the current configuration to a config file (including pools).    Much of my job is streamlining and automating processes so I saw a chance where some steps could be removed 

Unfortunately the languages I'm familiar with are VB, VBScript, VB.NET, ADSI, PowerShell, and some C#.  I was thrown into VB and vbscript with my job years ago and haven't had the time to venture into much else outside what is directly job related  

IF such an autotune adventure were to be undertaken, one way to go about it would be limit the range of the autotune.  So if the --freq=850 is specified, it would test a range of say 200Mhz above and below (if needed but not likely).  It would certainly take longer....a lot longer, but if autotune is only run once then I really see no harm in that. 
Also, you could have autotune dump results to a file once completed - and if you're adding config file support, you could dump the autotune results into a JSON formatted config file that could be loaded on startup. 

Just ideas.  If I knew C now, I'd be playing with the code. 

What?  You wouldn't like a challenge like that?  J/k

Makes sense.  But if they use different pll dividers would it be possible to create 2 autotune functions - each confined within its own pll divider?

That's kind of like the code I like to tinker with but unfortunately I don't know the language cpuminer is in and learning it takes more time than I have right now

So since any frequency is allowed now and not just 25Mhz steps, does autotune initially start with 25mhz steps and then fine tune it from that point down to something like 5mhz steps?

Sorry... I'm using sandor's cpuminer fork with the autotuning features.

I just have them hooked up to my win 8.1 pc. 

Considering it came with around $60 worth of accessories that I didn't have but wanted anyway....I didn't consider it too bad.

I (and apparently others as well) had seen no mention of 14mhs units for anywhere near that price either.  The closest I saw was 13mhs for 1800 or so.

Some are using 49.9k, some are 50k.  Some gridseeds have trim pots on them, others have 2x100k resistors in parallel to equal the 50k.  I just used what I had on hand since I had a surplus of trim pots and 100k resistors  

I've only got 6 gridseeds but they're running along nicely at 3MH/s.  I put in a pre-order for one of the GAWMiners 1MH/s Fury units that came with just about everything including the kitchen sink for $199.  It was a deal I couldn't pass up since it came with the miner, all power cables, network cable, raspberry pi, pre-loaded sd card, and free shipping.  

Wolfey - I'm using multipool.us.  Overall I like it better than clevermining mainly due to the fact that you can see what's being mined at the current time, as well as your balances of each coin.  They don't automatically exchange and payout in btc like clevermining though - although I wish that were an option.  They do have full cryptsy integration though.  You have more information and control over what you're mining at multipool as opposed to a couple graphs with no specific information.

I enjoy my voltmods - not sure about dyland and what went wrong there.  Each of my gridseeds hovers around the 500-530kh/s.

I don't have a raspberry pi so I can't help you there, but I WAS using Clevermining.  WAS being the keyword.  Recently (this past weekend actually) I noticed some VERY inconsistent results from that pool as well as a very high reject rate (which they say is a 'false reporting'...not sure how much I believe that).  For example, I had 3 gridseeds pointed to that pool and when I would start mining it would be sometimes 3-4 minutes before a single share was accepted.  Then a few more would get accepted, and then another 5 minutes or so before another share was accepted.  Their graph of my hashrate would fluctuate between 1.5Mh/s down to almost 0. 

Using the same version of cpuminer I switched back to Multipool and there was no delay in accepted shares, lower reject rates, and more consistent hashrates around the 1.4-1.5Mh/s range.  Also at Clevermining I have 0.00000016 BTC "Immature" and 0.00046437 BTC "unexchanged"...that number hasn't changed for the past 2 days, leaving my "payout" just below their threshold. 

All that adds up to something that seems a little "off" so I've switched all my workers over to Multipool. 

I came across an old phone and had this crazy off the wall idea....has anyone thought of using an older android phone running Ubuntu to control miners?  Could utilize USB OTG to connect a hub and go from there.  Just a thought...might be more powerful than a raspberry pi....and for those of us with old phones laying around it could provide a useful re-purpose of tech.

If you're just bridging the one or two locations then it should work.  When I first did the bridge mod I just used a small portion (1/4 inch or less) of the lead from a 1/8w axial resistor with a bend in it for easy handling with a pair of tweezers.

Yes - those 4 posts are what screws down the circuit board to the other half of the heatsink.  I just used a pair of pliers.  The circuit board will likely stick to the heatsink pretty good, unless something has changed, there are no components on the bottom of the circuit board so it's ok to pry a bit, but don't use anything metal (don't need to introduce scratches to the circuitry and create a source for a short).  

If you're replacing the thermal pad with paste be sure to insulate any exposed pins or circuitry (I used electrical tape), otherwise you'll get a short.

I've been testing the .9e build and it's been crashing multiple times since yesterday.  I've been testing various settings and whatnot, and have now switched pools to see if it's a pool issue.  What I've found in the debug log was an error encountered:  [2014-05-06 09:11:38] stratum_recv_line failed.  It happens randomly as well.  I've seen it happen in as little as 10 minutes, and as long as a couple hours.

Anyone else see something like this?
.9d runs fine, .9e fails with that error - same pool.

Avast is obviously wrong because it's not a bitcoin miner.  It mines scrypt based altcoins....not sha256 based bitcoins.  Nothing to worry about 

I found the same thing as Kergekoin.

Use a fine tip...or better yet...a hot-air system is your best friend.
