Yeah, I gave up on that.

Max.Wyght I with Kevlar on this one, and a small word of warning if your having to ask for this level of information maybe you shouldn’t be thinking about messing with stuff like this.

A good few years ago when in collage, I remember being in a lab messing around with PSU’s and one of the lads ending up on the floor dribbling and shaking because he wasn’t paying attention! after the paramedics had been and given him the all clear all he said was “I didn’t think it was going to bite, as it was unplugged!”

If you insist on this adventure, please please please promise us that you will do a lot of research before you start, I don’t want to read in the new that a fellow miner has blown himself, or his house up messing about with an old HP PSU

Luckily, I’m an extremely cautious bastard.
I know that even unplugged PSUs are dangerous(Whenever I clean up my desktop I make sure to kill/drain/whatever you call the PSU, by first unplugging it, and then shorting the power inlet, and working only on a wooden surface).

I was hoping that he could provide me with at least an image of the solders so that I won’t have to research as much, but unfortunately it’s not the case.
That leaves me two options;
Research the bloody thing till my eyes bleed, or talk to my old man… *Shudder*

I don’t have schematics or pictures, as I said I did it with a multi-meter and a lot of know-how. You’d need the same because HP power supplies come in all shapes and configurations.

Well…
Thanks anyways :)

If i were you i wouldn’t risk death and just buy a seasonic :P

It’s not just about saving 300$(More to the tune of 1200, but w/e).
If I do this right, I’ll have gained an actual life skill.
I’ll level up in a way.

You can use a resistor of any size, really, so long as it’s rated for more than a couple watts. Here’s a nice 8ohm one rated for 100 watts that should fit the bill nicely for what you’re doing: [url=http://www.parts-express.com/8-ohm-100w-non-inductive-dummy-load-resistor–019-020]http://www.parts-express.com/8-ohm-100w-non-inductive-dummy-load-resistor--019-020[/url]

This is the ‘professional engineer’ solution, mind you. You can still go the screwdriver route, but if you burn your board in doing so, don’t say I didn’t warn you.

Could you post the schematics on where to solder everything and how to connect it to power the gpus alone?

will send 100 ftc once my rig starts working.

Hi Friends,

On wemineftc pool, I am getting 25% less than
the calculator says… is it normal ? What
is your experience ?

(no HWs Rs around 0.5%)

Thanks in advance

paste your config? atm i have 3 + 1 7970 running in a rig. They are close together until those openrigs come in! [url=https://openrigs.com/]https://openrigs.com/[/url]

i have one that sits at 80 degrees but its stable.

Here is a pic of my 2 top rigs.

I want to start lending loans, initially for use in the market place. I could also offer this as a service product, within the market place.

I see this as good way to promote feathercoin and the market place. I will start the process today, however dont get too exited! As i only have around 13 feathercoins to my name which i bought. I know, not much liquidity there ???

I would needsome help from people and donations to the pot, to give this more lending power/liquidity. Alternatively if you dont want to donate to the pot, i could effectively act as a broker. You send an amount of coins and I agree interest rate with you and a lender. The lender repays I return the funds to you and take some of the interest rate or a small fee for my work.

In case you want to donate my address is:

6sWUEyAxwf5mtRbgQoGY3YtMHhcxm3mUEq

So today myself i will start lending just 1 to 2 Feathercoins per loan. This could be perhaps if someone is just short of making a purchase on the market place. This would also start to build trust with users.

I would love to hear your thoughts on this. If this grows a bit, I will advertise as a service in the market place.

Many Thanks :)

The whole point of a deflationary currency is 0% interest.
You can’t generate more $$$ when there’s a limited amount of coin that will ever exist.

[quote name=“new2crypto” post=“44725” timestamp=“1387137676”]
Just a little reward for continued loyalty to the forum. With that in mind, to receive your coin, there is just some minor criteria that you must meet:

*Must have made 20 posts on the forum

*Must have added yourself to the Feathercoin map

*Must have +1 rep score

As soon as you meet this criteria simply post your Feathercoin address below in the thread and you will receive your reward.

This is only possible due to the generosity of other members, who have kindly made donations. Members who have made donations so far:

BikerGSX
Bunnywinkles
Kevlar
Myself

So a big thankyou to them. If you would like to make a small donation to the pot for distribution to Jr members then please send FTC to this address:

6pzShJBkWERKCbZ9RhVtaRjsvkwdwKCSrs

If you send me a message I will give you an honourable mention here.

*All currency received will be strictly used only for this offer. I will keep the thread updated with all donations received and rewards sent. If for any reason the offer stops, any remaining coins in the pot will be returned proportionally amongst the donors
[/quote]

I’d love to get a donation of 1FTC, but sadly, I’m probably past the point of being called a junior member =/

I’ll probably send donations once my rig starts working…

That would be worse. You want to equalize the potential across the caps, not short it to ground.

I think there was at least 3 big ones in the one I was taking apart. Your mileage may vary.
[/quote]

How do I go about equalizing them?
[/quote]

Well like I said I used a dummy load because that’s going to be the least dangerous and will drain it slowly over a few seconds instead of in a bright flash of sparks. But if you go the metal screwdriver route, watch out for broken plastic and don’t stand in any pools of water.
[/quote]

That’s a given.

but if I want to get a dummy load, how powerful should it be, and where could I get one?

It wouldn’t be the project to start with, that’s for sure. You’re much better off starting with something small that’s a little more forgiving of learning.

Those caps in there have some tremendous voltage potential, and can KILL YOU, even if the damn thing is turned off AND unplugged. I’m not kidding. I’ll say it again: It’s powered off, it’s not plugged into the wall, and it has the potential to cause death. I used a 100k ohm dummy load to drain the caps individually before working on it, but I happen to have one laying around from my ham radio days. If you’re going to do this, learn about how to discharge a capacitor safely first.

Don’t believe me? Watch what a really big cap can do: [url=http://www.youtube.com/watch?v=coW1RHUsf_I#ws]Big Capacitor Safety[/url]

I’ve seen people discharge a cap with a screwdriver, but god help you if you’re not holding the plastic handle and are accidentally touching the metal. This is the equivalent of moving a tank of gas around while holding a blowtorch.
[/quote]

wow…
ok, so if I don’t happen to have a dummy load lying around, and I want to drain the caps with a screw driver, what sort of precautions should I take?

Would tying a grounding wire to the metal bit of screwdriver and then tying the damned thing to a 6 foot pole be too much? Or should I go with something longer?
I sort of like not needing a pacemaker…

Also, how many caps are actually in there that require draining?

So after reading around, I found out that server PSUs are way more efficient and stable than normal PSUs(also, they were designed to run 24/7),
What’s more, U found that not only is it possible to power the GPUs with one, but it’s quite common in the crypto community.

So my question is:
anyone tried doing that?
I found a schematic of which pins I need to connect to power one on, but I couldn’t find a way to modify the blade connections so that I can connect molex females.

anyone succesfully mod one?

this is the PSU I was planning on buying:

[/quote]

Yep, I’ve used a few of these in unrelated projects.

First thing you need to know is they’re great.

Second thing you need to know is they’re LOUD. Like you won’t be able to sleep in the same room loud.

But, assuming you’re good with that, then the next thing you need to know is let go of the idea of ‘simple’, ‘adapters’, and ‘reversible conversion’. I looked, such things just don’t exist. Instead I ripped it’s case off and soldiered wires directly to the board, using a DVM as my guide. The result is a Frankenstein looking beast with manually rigged switches to turn it on and off. But you can’t beat the price for the output you’ll get.
[/quote]

Assume I’m a literal noob when it comes to electrical engineering.

Figure i still have a chance of converting one, assuming I have everything required?

Wow those are cheap :o

I was gonna say why not seasonic but now i see why :p

Cheap as hell, but still superior to any cpu supply

Need to find myself a case that support for 2 or 4x GPU with spacing (with use of extenders!)

The closest i have found is: [url=http://www.komplett.no/corsair-carbide-air-540-cube-case/783884]http://www.komplett.no/corsair-carbide-air-540-cube-case/783884[/url]
But this dont separate/space the cards away from mobo.

The issue is that i have an Asus Maximus V Extreme E-ATX Mobo, that has alot of pci-e 16x slots. BUT freaking fixed slots, meaning on 2x gpu i have to use specific port.
which isnt spaced well from each other (beyond stupid since they end up cooking eachother!).

Do i have to go DIY on this or does such a product excist out there??

It also have to look like a computer case and not a standard mining rig (its for my main comp)
[/quote]

go with a tech bench or something similar.

thus one:
[url=http://richchomiczewski.wordpress.com/home/trays/]http://richchomiczewski.wordpress.com/home/trays/[/url]

does open cases that are supposed to be pretty decent, but yoy’d still have to stick a box fan in there.

I’d love to know how you set it up to do that, because I’m planning on setting up several rigs in the near future, and I don’t feel like doing the monitor shuffle for rig maintenance…
[/quote]

quite easy, search google for a (manual) dvi switch :) should not be too expensive (around 10-50$ depends on how many you want to switch). HDMI-switches or better HDMI-matrix-switches are a “little” more expensive (100-1000+$)

Hi!
I’m new to FTC and find the concept very interesting and especially very useful for online economy. I know this is something what you’ve probably discussed already but I have the feeling that many traders have forgot about the purpose of an alternative crypto currency. Or it at least seems so because the time hasn’t arrived yet to use FTC in a very useful way. I try to explain what I actually want to say:
At the moment every alt. coin currency is just a high risk investment with no real use but actually it should be a currency you can trade and buy things with it. Of course there are already some shops who accept BTC or FTC but there are no such shops where the mainstream would buy because it’s too much risk for these shops. So mainstream shops will only accept FTC if the price is stable. But if we look to BTC we see it’s almost 5 years since the first bitcoin has been created and there is no hope for a stable price soon. But at some time this must have an end, right? When will the prices be stable? Maybe when most people on earth change their conventional currency in alt. currencies? Because as long as there are an increasing interest in alt. currencies the prices will raise (and drop sometimes). That’s the way I see this, maybe I think about it in a wrong way, so I’m very interested what’s your opinion. To finish my thoughts: It could be take years or even a decade until the first bigger shops which are interesting for the mainstream start to accept BTC, FTC etc. What’s your opinion? Do you think that it’s possible that alt. cr. currencies never will be becoming a useful currency that we use like the national currencies we use at the moment? And the last question which actually brought me to start this topic: Does it make sense for now asking shops (like gog, steam, amazon etc.) whether they will be accept FTC in the (near) future? Or is it too early?
[/quote]

While BTC isn’t very stable, LTC and FTC are pretty stable, with prices of 29-36$ and 0.4~0.6$ respectively.
