I think every country needs to add a team member, I intend to add some new members in China.

Sign me up for Japan!

Even if I think I am the only one, so: does it make sense to you guys?

BTW, already spreading the word here…

I love the ATM, I’m jealous tbh :D

But is there any way you can add a credit card reader and net access?

You know, so when you combine one of those in a town centre with https://forum.feathercoin.com/index.php?/topic/7206-dev-introducing-featherpay-point-of-sales-device/

I think that is the idea… but I’m not sure what UM is up to… he is quite silet lately so I’m sure he has a “bomb” hidden and he’s waiting the right timing to throw it! :)

Would there be any reason for a business not to seriously consider taking FTC as a method of payment?

The more I think about this issue the more I believe that:

• price volatilty is a big deterrent when you still buy your things in fiat

• innovation is not that easy to be digested by the average (typically conservative) small shop owner.

IMHO the first still remains the biggest deterrent… but I’m going OT…

Just checking that we didn’t miss any points now there is a tested version of Feathercoin 0.8.6.1 available for PublicBeta testing.

Hey wrapper,

do you still need the hashing power on the testnet?

Wow, look at that shiny box! It’s awesome!

And your devotion is incredible.

It seems like a very sensible and well documented option.

To be precise I really appreciate sentences like “realm of the regular user”; as you pointed out only the big money industries will be left mining when prices get prohibitive and that’s not good for the decentralization.

Just keep in mind that FTC is still a CPU mineable currency and it would be great if it could remain like that after the algo change. I know it utopy but…

Hi guys!

I have some spare time and decided to use it to group some old GPUs I have mining around in one small open rig with an old CPU/MoBo/RAM etc. I only have a 500 W PSU which is not going to be enough to power all the three cards, so I have two choices:

-dual PSU

-buy a bigger one

The cards are: 5870, 6850 and 7870 and together they’re going to need around 600 W more or less. I know I can make it with a 1000 W PSU but those cost a lot and I have 2x 500 lying around unused!

I found this video on youtube but there are some comments with guys reporting burning the MoBo etc.

I understand that the second PSU should only be linked to the 12 V plugs of the additional GPUs and all the MoBo related connections (risers included) should go to the first one.

But still these three are not exactly “crappy cards” I can sacrifice and would like to hear some first hand experience from people I trust.

Any advice?

Svennand, first of all let me thank you for this very detailed and informative post.
I read you “adventures” with mobo frying here on the forums so I know you have lots of first hand info and that makes this thread even more valuable.

Let’s see if I got it right. The most important thing is: if you have more than two cards, you have to use powered risers or you will fry your mobo for sure. An the reason is the power overhead sucked up from the PCIe bus. If you have the powered risers the additional power is taken from them (the molex or whatever is connected).
Am I on the right track?

Ok. So, keeping in mind that I decided to switch the 7870 for a 6970, I made some calculations:

Card – Power ----> Overhead
Gpu0 (HIS 6970) – 250 W ----> +25 W (8+6)
Gpu1 (Sapphire 6850) – 200 W ----> -25 W (8+6)
Gpu2 (Asus 5870) – 188 W ----> -37 W (8+6)

These are figures for Scrypt mining according to this page. I verified that those numbers are quite spot on.
So, looking at these calculations I should be good to go, am I right? The mobo should be capable of handling the overhead if I put the 6970 on a 16x slot. Even without the powered risers. Am I right?
If that’s not true, the card itself should burn the mobo even if used alone in the rig. BTW I will have to buy risers anyway so I will have no problem at all I think.

As for the second PSU, I just connect it and I’m ready to go. Good news!

Another thing. I am thinking of an “anti-dust” layout where the pc is “upside-down” to avoid becoming a dust ball in a week. Something like this (poor) sketch is representing. Is there any risk in this kind of arrangement (that I’ve never seen around…)?? Everything would be obviously nailed down with nuts and bolts and on the MoBo, only the CPU fan and the ram are present. I don’t see any side effect in doing this but I may be wrong.
