its integrated as a service

so you start it like this sudo service cgminer start/stop

I see what you're saying but I wanted to check the binary does actually run before installing as a service... it should run. I would expect if I installed the whole thing it would still fail

What's the router?

WL500G-Deluxe so that's a BCM4702/4710. One has a very old Oleg firmware, the other has what appears to be the latest DD-WRT from 2010. I've only tried the DD-WRT one andthat's the one that gave illegal instruction

a NFS share on start-up could well work. I think you could do that with a start-up script in the admin panel. Mount it top /opt and you should be golden

Though that does mean you'll need another computer on all the time... so why not hook the miner up to that???

because then I'd need a USB hub and mine's taking ages to arrive from china.

Just tried running cgminer-3.3.1-mipsel on dd-wrt v24-sp2 (build 14929) ((old - will try upgrading...):
Code:
root@router:~# ./cgminer -n
Illegal instruction

Seems I'm just talking to myself here using this thread like a diary. I was hoping someone might chime in and tell me a way to monitor the temp on the USB Eruptor.

Tried a USB flash drive in the Pi and it works... and the Eruptor works on the laptop (I've no USB powered hub yet to help with testing) which all points to the mips compiled cgminer... but different versions and I still get 4bytes etc and so forth.

I still think I've overstressed the Pi USB ports somehow. It would be good to be able to know that the ports are ok for sure.

update:
Now running on a BeagleBone but need to create the /dev/ entries for /dev/ttyUSB0 or AMU0...

 I don't want to use a powered USB hub if possible since I only have one miner. However, I think the problem is that I need to put the cgminer executable somewhere and that therefore needs extra USB storage right - and therefore a USB hub.

Unless I mount a network share...?
166  Economy / Service Discussion / Re: BITNZ Exchange - Reliable? on: August 04, 2013, 10:37:43 PM
An alternative in NZ would be good. The guy running BitNZ... I think sounds like a busy guy and doesn't need the income so much. I think it's run, certainly at the start as a charitable thing for Bitcoin point of view.

As such, I hate to say it since it's a profit making thing but... don't moan too hard as we need the site up and running.

Hopefully an alternative in NZ will turn up at some point as a backup.

I'd also like to see a market order option to help newbies. That change didn't happen either which makes me think it's always going to be a bit neglected.
167  Bitcoin / Mining support / Re: Bitparking says 0mh/s on: August 04, 2013, 09:02:04 PM
Yup, USB HDD is dead too.

Let this be a lesson to you folks - if you plug your Eruptor straight into your Pi your'll burn it


shameless hotlink...

meanwhile... on the laptop:

Code:
AMU0: invalid nonce - HW error
I wonder how hot the Eruptor is running and what it's limit is... perhaps a fan is essential...
168  Bitcoin / Mining support / Re: Bitparking says 0mh/s on: August 04, 2013, 08:13:44 PM
Right... must be something to do with the RaspberryPi... no such errors from the laptop. Perhaps the USB port couldn't handle the heat.... will have to test some more...

edit:

Code:
raspberrypi ~ $ /opt/vc/bin/vcgencmd measure_temp
temp=56.2'C
^ though this is the CPU rathe rthan the ethernet/usb chip which also generates it's own heat. It's possible the heat from the Eruptor conducted through to the Pi and that's effected the Pi usb chip... however it's strange that the fail happened as it did; only slightly...

Next thing to do I suppose will be to try a USB HDD.

170  Bitcoin / Development & Technical Discussion / Bash script to sound when coins received - need debug on: August 01, 2013, 09:28:23 PM
Goal: Make a sound when balance at an address reaches a set number of confirmations

So far:

Code:
#needs:
# - pulseaudio - for paplay
# - curl
# - blockexplorer not 404

address=$1
confirmations="6"
balance=$(curl --fail "http://blockexplorer.com/q/getreceivedbyaddress/$address/$confirmations") || { echo "Unable to retrieve balance" >&2; exit 1; }



while $BALANCE=0
do
 sleep 1s
 echo $BALANCE
done


echo $BALANCE at $ADDRESS received with $CONFIRMATIONS confirmations.
paplay /usr/share/sounds/startup3.wav

Needs a bit of tweaking.

I did a search and found bash scripts in this dev section so I'm posting here... but it doesn't seem the best section to post in, sorry if it's wrong
171  Bitcoin / Bitcoin Discussion / Re: idea: QRcard - fully offline hardware wallet on: August 01, 2013, 05:48:15 PM
All we need to have something workable ASAP is an android device with a camera and eink... but I don't think one exists (other than a Nook with USB camera clumsily hanging out)

Other than this I suppose there are android phones and cheap chinese tablets that you could solder over the wifi or try to put a switch on the antenna but they're not that small.
172  Bitcoin / Bitcoin Discussion / idea: QRcard - fully offline hardware wallet on: August 01, 2013, 11:40:53 AM
 2 items required:

- eink display
^ display good enough to show QRcodes, eink seems most appropriate
- camera
^ this can be cheap and low quality.

The devices generates addresses and transactions, that's all. Interaction is done via the screen and camera, nothing else.

While I think the various hardware devices are great this is a lot simpler to communicate to people than USB sticks.

It would be simplest to use Android, or something that can run python and use a client that already exists.

I'd like to make such a device but it's beyond me.
173  Bitcoin / Electrum / Re: Online label syncing plugin in Electrum 1.7 on: August 01, 2013, 10:01:41 AM
I just want to be 110% sure about this - we're just syncing labels which can be used to make a record of what each transaction was and is for, for easier accounting.
Transactions are noted but these can't be abused in any way and private keys aren't transmitted.

Thus, the encryption is there for financial privacy.

Just want to be totally sure that this is what it is?
174  Bitcoin / Electrum / labelectrum - labels only? on: July 31, 2013, 06:51:13 PM
I'm thinking of using https://labelectrum.herokuapp.com/ to syncronise my labels.

But I don't want to synchronise wallets because I see that as a risk even if its ssyncronisetore encrypted. Are the private keys transmitted or just the labels / history?

p.s. it would be nice to be able to freeze multiple receive addresses in one go by holding the shift and ctrl keys

^ was worse when I had something plugged into the Raspberry Pi hub next to the USB Eruptor. Ran ok for the few days. Now it's crapping out. Very hot to the touch but not sure how much. Have that basic included heatsink on the back but no fan. Don't want to put a fan on it really... noise...
176  Other / Beginners & Help / Re: Is the Bitcoin ecosystem sane? on: July 30, 2013, 11:47:02 AM
Acceptance is a very important indicator of how well Bitcoin is doing.

However, look at gold. I've tried a few times to see if a shop will accept a gold coin and they never do, or if they do they like to make a fat profit from it. Yet gold is still seen as a currency and countries in particular use it for payments.

The question then becomes,
how much is speculation and how much is real value? That's the hard one to answer. In particular it's difficult to unpick people who have a small store of emergency funds as BTC because it's harder to confiscate than gold for example.

179  Alternate cryptocurrencies / Altcoin Discussion / Re: Bitcoin bridge - Ripple on: July 23, 2013, 07:48:31 PM
The point I'm trying to make is that debt has been ill advised for a very long time.

 Yes, it has the advantage of making new connections in the financial system but it also allows for ebbs and flows and massive crashes due to the extra linking. Movements like this are natural for any network. When you take out a loan you allow the lender more than interest - but also an extra facet of control that is not at all obvious.

 Unlike Bitcoin, Ripple is based on this same broken system.

 I don't write off advise from a source because that source is unfashionable. All the major religions have something to say about debt. If you want to write off religion as a source for what people thought in the past then there isn't much left in history.

 Science is like a disrespectful brat right now to it's parents which are religion and philosophy. The attitude is slowly maturing.


In reading this thread we've seen a few people who don't know what Ripple is, nor how it is different.

With Ripple you are trusting other people to pay you back. That is "Promise to pay the bearer" as printed on GBP notes and specifically advised against as a bad idea in the bible. It's an IOU but unlike a Hawala notebook it's digital. Howeverm here's the interesting bit: you can infer trust to someone you don't know via someone else. Thus, if there's someone on the forum yoiu don't know you might be able to get trust via that someone else.

This is good when people are paying their debts but if it goes wrong the debt default Ripple goes through the entire system.

The other good thing is that Ripple facilitates setting up an exchange through the gateways. However, it's not as easy for the average user IMHO.

Finally, the whole thing is glued together with XRP and that is dodgy.

Scam or not, you must at least be aware of all this stuff!

wait you are referencing a book written a few thousand years before modern financial systems were developed for giving financial advice?

come on....

What I mean is that at a setting of 0.80/-0.80 I find that it tends to get to miss the very small timescale(daily), get it wrong on the short timescale(weekly) but get it right on the medium (monthly) scale.

This is of course very general and it hasn't been tested enough. The short weekly timescale is a shame. For example in the log here I have:

Which of course is the very opposite of what you want right!

Now, come to think of it, I remember why it caught the 70 dip - it was because I manually intervened and then used the bot to buy if anything changes.

I was hoping that I could use the EMA to catch those very large changes and basically create a less speculative more stable level but it doesn't seem to do that and just holding USD would be better at that.

Anyone had any wins with EMA?
Even though it's made losses I somehow how feel safer thinking that something less human is watching some coins for me. I'm not sure if it's too early to say experiment failed.


What values do you run it at?
Always seems to buy low and sell high for me... but it did catch the more major dips so far which is handy

Been running it for a few days, tweaking it ever so slightly and watching the results.

One thing I've noticed is a profit calculation hasn't been shown afaik for me in the time I've been running the bot in simulation mode.

http://imgur.com/S3ik8WH

Any known reason for this I've missed.

That is what it suppose to do. It follows the flow of the market so if the 'flow' changes a lot in a short time you will lose some money.
But once the market moves big in a certain way for a longer time period you will be on the right side.
