Other / Offtopic / Thank you for donating to the community project!

on: October 25, 2013, 12:29:30 AM

Hello! I just checked my bitcoin and I noticed that two transactions were sent towards the community project I started a few months ago. Though the amounts are small (.0002 & .0009), every little bit helps and I wanted to thank them and make sure they know I recognize their generosity. I will keep track of this and place it towards equipment for the Community Tool Shed.
Thanks! D337z

Other / Offtopic / Trying to access Intel RAID from nonIntel computer

on: June 26, 2013, 10:14:16 AM

The data's there and it's a fakeRAID from what I can tell. However, mdadm can't seem to find any metadata on it. I was wondering if anyone knows of a way to access the RAID 5 data via two RAID disks (I only have the two USB adapters to connect to the laptop) on a nonIntel system that doesn't have RAID. Any way to read the data via mdadm? I mean, if it's fake RAID, anyway, it shouldn't be chipset dependent; right?

Economy / Goods / Anyone interested in wind and solar power generators?

on: June 23, 2013, 09:13:17 AM

If anyone's interested, I'll get selling. The wind generators will probably run about 45 BTC, but will supply about 2500 watts of power. I can compile together a complete system based on what your situation is and ship it all to you in a semitimely fashion. I try to find the most efficient setup based on location and what items are available. Shipping batteries would be difficult, but not impossible. These alternate power sources can be a gamechanger when it comes to mining BTC since it will greatly offset the power consumption of your systems while adding the possibility for some money received from your electric company (unlikely, most likely just a much lower bill). The return in investment can be seen in about 1.5  2 years generally. Please let me know if anyone is interested.
Thanks! D337z

Other / Offtopic / 1.5 BTC Donation for a Project

on: June 16, 2013, 05:46:03 AM

Hi everybody! It's D337z again!
Anyhow, I'm just going to get right down to it. I've got a project I want to accomplish for the community and not enough income to fulfill it myself. So, I'm asking if anyone wants to donate to help me out. Now, I know what many of you who don't know me will say, "SCAM! He's totally scamming you!" Well, I'm going to tell you right here and now that a donation is just that. You don't get anything out of it but the satisfaction that your money might be going to a good cause. And yes, I said might. As with any other donation you've made in your life, unless you're standing right there, you can't be sure where your money went to. Now to tell you what your donation is supposed to go towards. I have quite a few neighbors around my neighborhood that can't take care of their lawns due to either financial problems or physical inability. So, I've acquired a 48 Volt batterypowered lawn mower via FreeCycle that needs 4x 12 Volt 9 Amp batteries to run. The problem is that I can't afford to get the batteries myself as they surplus to over $120 total. I can make the repairs myself, so I don't need to ship it to Craftsman to get it fixed. I was wondering if anyone would like to spare some BTC for the batteries and possibly travel expenses in case I branch out to other people outside of the neighborhood who need free lawn care. The way I see it, my home town here has a law that says that grass can not exceed 8 inches in height or they will fine the owner of the home. If someone can't afford to be mowing their lawn, they can't pay the fine. If they're unable to physically mow their lawn, it's adding insult to injury. I already know of a few people around the neighborhood who could use my free help, so I'll be making at least a small difference. The mower will last about 10 years on the 4x batteries. And any excess donations will go towards other community projects...which I haven't decided on yet but may include household wind turbines.
Well, feel free to forward any questions or accusations to me personally.
Take care! D337z
Donations to: 16U1teSxRLpP64NeSAJ3CSoEqwZq4fgonT Every little bit helps!
Edit: I think I've decided to open a community tool shed where the community can get what tools they need lent to them for free. I think it's the only way to be truly fair about it.

Bitcoin / Mining software (miners) / Best darn idea since pool hopping!

on: August 21, 2012, 04:31:11 AM

Ever get that block solved that you wish you had been able to hold onto yourself? Well, why not? Solo mining won't accept the partial results that pools will, but they will accept the solved block. SO, why not have your miner mining for both your solo miner and your pool miner at the same time? Only, when you get that block solved, submit it to your solo miner for the full 50 BTC! Yes, I know that this may cheat some pools out of BTC, but they each still have the data leading up to the block. However, if done right, this might help to even the playing field for those with slow miners.

Alternate cryptocurrencies / Altcoin Discussion / LTC mining through PowerPC capability?

on: August 19, 2012, 02:29:53 PM

Hey, just wondering if anyone has done any work on mining via a PowerPC that I could expand upon. I have a small plan that will allow mining via a very simple device, but my scrypting skills are below par. I suppose I could take a swing at it, but I'm far less familiar with scrypt than I am with SHA256. Are there any papers on it that I might be able to work from? Thanks! Erick

Bitcoin / Mining support / From nothing to something

on: August 19, 2012, 02:12:07 AM

Hey guys, I was just wondering how many of you successful people got your start. I other words, how could one go from hashing one bitcoin in 3 months at a rate of 28 Mhash/sec to running multiple rigs in the Ghash/sec range using only bitcoin? As it is, I've found it to be a waste to try hashing bitcoin at that rate since I only get maybe .01 BTC every 3 days or so if I'm lucky, so I've been using my hardware for BOINC to help with scientific and medical research. I'm open to suggestions if you've got 'em. I'm on a low budget so I can't really be spending any money on equipment other than what I generate; so I'm looking for ways to make BTC. I've taken to selling items for BTC, but it's slow going.
Can anyone offer any advice? And what are the chances of me hitting a block with that small of a rate?

Economy / Goods / [WTS] Arduino Mega2560 Rev3 for 7.5 BTC

on: August 14, 2012, 06:57:54 PM

Hey guys, some of you know me, some of you don't. It's been a while since I've been on, but I'm back and trying to get something going to keep my life in order. That's right, I'm jobless. So, I'm going to start offering a few items on here to make ends meet. I'm offering an Aruduino Mega2560 Rev3 (Newest model) for 7.5 BTC. I'm charging 7.5 BTC because of the fluctuations of the market. And so, I'm taking the margin into account. This also helps to pay for any taxes between countries I might incur. If you're interested, let me know! I can also get a few other Arduino models if you're interested. I'll toss you a price based on what you're looking for.

Other / CPU/GPU Bitcoin mining hardware / What amount of BTC are people seeing each week from HD5970?

on: April 01, 2012, 04:42:21 AM

Hey all! It's your loveable, hugable D337z! So, I was looking at the possibility of getting an HD5970, but I was wondering how long it would take to see a return on investment. Now, I'm decent with math, but I have trouble getting numbers flipped around. Also, realworld beats paper...because it has rocks. So, what are some of you seeing out of your HD5970 cards in about a week? Or, better yet, how long until return on investment?
Thanks!

Bitcoin / Mining software (miners) / Anyone interested in teaming up to build a PS3based miner accessible via XMB?

on: February 20, 2012, 05:37:58 PM

Hey everyone! I was wondering if anyone wants to tackle the daunting work of tossing together a PS3 based miner that you don't have to have Linux to use? It'll be based off of the PSL1ght SDK and accessible via CFW without the need to install Linux. This gives it more resources and makes it a viable screensaver for PS3. It also opens the bitcoin mining scene to any PS3 users. Via Linux, the PS3 should mine at about 15 Mhashes/s. However, with some tweaking, I'm sure we could squeeze something more out of it. If anyone wants to help tackle it, I'm way over my head with this project so it'll be a learning experience. Anyone up for the fun?

Economy / Marketplace / Friend's apartment burnt down. Accepting donations to help her out.

on: February 15, 2012, 09:38:52 PM

Hey everyone. I don't normally do this sort of thing, but I'm asking if anyone can help out a friend of mine who's apartment burned down yesterday. She's lost clothes, books, her bed, laptop, etc. so I'm trying to help her rebuild her life. I would appreciate if you could help me help her too. I'm accepting donations via bitcoin, paypal, dwolla, etc. The addresses are: Bitcoin: 12USr17HQQNse3NZM8foyVM5KbLsS3quwADwolla: 8125189397Paypal: Cryo_rebirth@yahoo.comNote that these do not route directly to her, but I don't want to post her Paypal address here as it's personal information. I'll route everything to her. Thank you SO much in advance to anyone that helps. It seems her Valentine's Day wasn't so good, but we can at least show her a bit of love. ^_^ D337z

Bitcoin / Mining software (miners) / Phatk2 Mod (Already seeing improvement!)

on: February 09, 2012, 01:43:39 AM

Hey everyone! I've decided to add Diapolo's GOFFSET option to Phatk2. In some cases, it works better, in others, it doesn't. Enable it to find out via GOFFSET! This kernel is for Phoenix 2.0.0. Currently, I test kernels on an ATI HD5450 graphics card. If anyone wants to help further my OpenCL expertise, I happily welcome donations to 12HWUSguWXRCQKfkPeJygVR1ex5wbg3hAq. They'll be put towards a new GPU or two (VLIW and GCN) and programming guides so I can compile optimum code. I already have the ideas, now I just need to get them out in the open. I'll also be helping Diapolo test his kernel and donate to help him out. (A day's worth of hashing each week should be enough) // This file is in the public domain

Bitcoin / Mining software (miners) / Proof of concept kernel coming up soon!

on: February 02, 2012, 04:09:57 AM

Hey all! I'm sort of new to the OpenCL coding scene and I decided I wanted to try my hand at coding a kernel for Phoenix Miner. So, I'm deciding to attempt to use 128bit (and possibly 256bit) vectors to compute SHA512 hashes and then truncate them to SHA256 for enhanced speed. ^_^ If anyone wants to help, let me know! I could us it.

Other / Beginners & Help / Use of 4x HD6990 cards

on: June 12, 2011, 05:42:53 PM

Hello, I am looking at building a rig with 4x HD6990 cards in it and I wanted to know if I would be required to connect each card to a display before their GPUs would be activated for mining. I know in past calculation programs, it was required for a display or null to be connected to at least one port of each card before the GPUs would do any work; has this changed with OpenCL or do I need to invest in null devices?
Thanks!
