So I recently purchased a smart phone.  Should I be tapping into it's single core processor to get some more coins?  I'm sure it's not very cost effective, but just out of curiousity, has anyone tried this?

Is there anyone who has used a cell phone to mine one of the cpu mining chains?

If the coin can be mined using a graphics card, then mining on any regular processor is going to be a waste of money.

Agreed, so I'm talking about Litecoins, Tenebrix, or Fairbrix.

I believe Solidcoin now has some way of going through a GPU.

You would have to write a custom miner to do it, I think. Unless it runs java, in which case you could try pooler's online one. I don't think it would be worth it though -- from my experience phone heatsinks leave something to be desired, not to mention it would kill your battery. To top it all off, those little ARMs don't have all that much muscle.

But if you try it, please post results =)

Gotcha, it seems like Java doesn't exist on android phones. 

I agree that it would kill the battery, but if I had a charger at work, in the car and at home, I'm not too concerned about that. 

My phone's only a single core processor though, which is more my concern.

Pooler's online miner doesn't work on my phone, I already tried that and posted in that forum.  Smiley

Once pooler releases the source, assuming your smartphone is android, it shouldn't be TOO difficult to port it into an android app (android is coded in Java, primarily). By kill the battery I didn't mean drain it, but wear it out -- IIRC that's why you're supposed to remove the battery from you laptop when plugged in and at 100%.

Or a native C miner and call it using the Android NDK.

I would be curious to know if we could mine LTC on a Raspberry PI. http://www.raspberrypi.org/ It's only $25 and really low power. And runs linux. :-)

It would be interesting to know how many k/hashes that device could do.

Sadly the $25 model has no Ethernet controller... but it has a HD GPU Cool

If I had to guess, you'd earn approximately $0.01 USD worth of litecoin per year, as well as wear out your battery and processor a lot faster than with normal use.

FWIW, there is a single line in the Mining Hardware Comparison mentioning a single core ARM processor. At current rates, a fraction of a megahash per second will take a long time to add up to much. The ARM architecture went for energy efficiency vs. raw speed a long time ago, it's a different animal for a different purpose.

https://en.bitcoin.it/wiki/Mining_hardware_comparison

Model     Mhash/s    Mhash/J    Mhash/s/$    ACP [W]    Clock    Version    Comment
ARM        0.187    ?    ?    ?    1200 MHz    cpuminer    Seagate Dockstar ArchLinux

A mining effort that could utilize such small devices as cell phones might avoid the seemingly entropic decay of the return on mining as mining computing power has increased. Weighting the return based on the computing power of the source, such as is done with some projects using the BOINC distributed computing client, would make the game much more interesting.

Gotcha, the megadrain on the processor hurts the ultimate battery life?  I'll remember that if I'm using a laptop.  Thanks!

I think it more has to do with the fact that the battery is discharging/recharging at the same time. There may be newer designs that fix this -- it's just a habit I've gotten into. The heat produced by the processor is also not good for battery chemistries.

"Wearing out" due to being kept at full charge constantly and not being discharged thoroughly will cause the older nickel-cadmium cells to no longer release their full charge, hence the advice to avoid leaving them charging all the time makes sense. Full discharges followed by a charge to capacity are good for such batteries.

The lithium ion batteries common in cell phones, cameras, and laptops ( the 18650 cell is most common in laptop batteries ) have rated lifetimes in terms of the number of charge/discharge cycles and actually benefit from fewer "deep" discharge cycles. Leaving them on charge with an intelligent charger ( as most are ) shouldn't be an issue if heating is not a problem.

Yep, I live in a hot climate and I keep my laptop's (li-ion) battery in the fridge most of the time.

Android includes most of the standard Java classes in its SDK, so all you need to do is port the litecoinpool source to an app and run it.
