It ranges from 45Mh to 55Mh.

hows your poolside hash rate??

finally modded them all.

Personally from the guide given here

https://bitcointalksearch.org/topic/lightningasic-gridseed-controller-firmware-v3-554542

I do not understand how you flash the Tp link nor how you connect that to the gridseeds

mine cost about 15 euros only trouble is its in chiense or japense! thank google for google tranlate!

AH my bad, I thought you needed both tp link + wii

then indeed it's alright

Who said you need to buy a Wiibox? Tp-link 703N can be easily had for $20 shipped.

nice but the price of an Tp link + wiibox is to expensive to ROI just for that few hasing rate if you do not have an massive amount of gridseeds at home.

If you have just a few, IMHO it's better to buy 1 extra gridseed cheap.

It will work with Tp-link 703N, just follow the guide on how to flash it. There is cpuminer included, its faster and more efficient at Gridseed mining than cgminer or bfgminer.

but its only for the controller not cgiminer or bfgminer . SO is the firmware new firmware for the gridseeds or new firmware for the contoller? and i have a TP link 703n, just not modded it yet or flashed it, where can i get an image for flashing it for controllering the grids???

Anyone with an overvolted Gridseed care to test the new per-chip auto-overclocking feature?

Yeah I seen that too! Hope I didn't waste money buying these :-(

Yeah BTC had again a big drop after some new chinese exchange closing news..

Well after running the pair of units for 12 hours with the newer mod (49.9k) and 12v fans I am seeing good stability so far at 1175Mhz. It has given me around 1Mh/s client side and very near that pool side with only a single HW error for each so far. Power usage is around 22-25W each but electricity is cheap here.

Is it correct what I am seeing on the auto switching pools websites, that profitability is ~0.00420BTC per Mh/s and falling?  That really is rather sorry. Oh well.

must admit my previous soldering irons were cheapish ones - mid range. no temperature control. So i had a bunch of different watt soldering irons. Not to mention different tips, some fitted but none fitted all the irons so annoying. And i had several soldering irons blow on me too, heating element fried type thing. cant cant it or even get new ones, so id been looking to get a temperature controlled one for a while, and when the cheap hot air station i had - used mainly for heat shrinking tubing - went as well i decided that i was gonna get new and upgrade. Then the bitcoin fase entered and i started modding the the sticks, after doing many resistor swaps i thought hot air station got to be easier way to do this. bit of online research and invested in the whole deal complete reworking station. has temperature controlled soldering iron - arrgh so sweet itself  - air hot mounted gun, temperature probe and surface pre heater too. Plus it has several arms for irregular PCB shapes - which turned out to be a bounes for the round PCB of the gridseeds. the only thing it was missing was a light and magnifying glass. But that nothing. Oh for those wondering its aoyue. Good name, plenty of spare parts. I thought it was American so i was disappointed to find it was made in china. BUT i must say its one of the few made in china that have quality, you can see straight away from the build quality of it.

Not looked back. For those that are more into doing it with soldering iron, or dont want to invest in a hot air station, i can highly recommend a slot type tip or even better soldering tweezers. that way you can apply the heat to desolder and solder at both points of the smd resistor at the same time. I spotted one and nearly got one myself but ive not used one but think it would be almost as easy as the hot air.

Seriously wolfey2014 get one great toy! JUST get a quality one - same goes fro anyone investing in a soldering iron - itll last longer more reliable and constant, id say aoyue, or weller, there others as well but i can think of the names of them now. And for those going soldering iron route make sure the iron has interchangeable types the type the slide over the heating element. Provides better heat transfer.


I did one the other day i found the solder started to give at around a temperature of 230- 240 on the hot air gun, i also plugged in my temperature probe to check the temperature at the surface of the SMD resistor, and it read 230, just as i touched the resistor with the probe it slid out of place across the board. thankfully i didnt knock anything else - still got a bit of a big nozzle on for 0402 series , new nozzle in post. Oh all temperature are in Celsius.

And soldering SMD is totally possible with soldering iron, and this guy makes it look like a walk in the park, serious skill!!!

I assume he replaced the blue cooling pads with an actual working one or non conductive thermal paste.
I tried it myself and this really gives you an increase in hashrate and much more stable operation.

Hot air gun is amazing! I got a cheapo one (Yihua 858D). Prob fake but it does the job. My only issue is that I don't know what temp to put it at or how to properly remove SMD components :/

The more I read you're experiences, the more I like the hot air station.....never used one, well after my glory days on the bench in a commercial facility stuffing pcb's...
Sounds nice! Cool! Another toy!

yeah defo air air station. i soldered smd  - not 0402 - wiht soldering iron, and its so much easier nicer even and quicker to solder smd resistors wiht hot air. seriously though wiht my station i only need to use one hand. and thats to hold the tweezers to lift the resistor off.
i found on mine about 230 c goes nicely, the next one i do - probably over weekend ill set the camera tripod and macro lense up.

for the first 10 I did I used a regular soldering iron with a magnifying glass while holding a flashlight.  They took a while.

I bought a pencil iron but once I got the hang of the hot air station I didn't even care to try the pencil iron.
