Yeah, OK. Maybe I'm a bit harsh. These things don't interest me too much usually. Kind of make me want to barf (like romantic movies).
And how is that working with the ladies for you?  Seriously though, sad music? The musical richness of Yann Tiersen is probably what got me through the whole video, otherwise I would have quickly skimmed to the end... just saying. Oh, and 42! |

I've never worked on a DS phat before, but I'd be willing to give it a shot - I certainly can get the parts and it shouldn't be too different from the lite.
I'm near Buffalo NY, USA - shipping for a well packed DS would probably run around 10-15 bucks.
Oh, that side of the pond... That is kind of a show stopper, I'm afraid. When you were to ship me back the thing it would almost certainly get stopped at customs and I'd have to pay for some outrageous yet totally arbitrary fee. Thanks anyway. |

Where are you located? I have one of the fatter DS, and it seriously needs a new touchscreen glass (dunno if that's the complete touchscreen or just some protective cover), as we lost the pen at some point and apparently some of us used pretty much everything to replace it, like rollerball pen covers, toothpicks, crawbars, chainsaws, small nuclear fission devices, etc... it is pretty messed up |

That's cool. Where are you?
Portugal Is that common in Europe in general? I honestly don't know... |

My first EV with lead acid batteries and lots of DIY / ebay parts still cost over $10k
Labor wise would be a couple hundred hours. Cost is highly depended on range and power. 20 miles is easy with lead, but 100 is damn near impossible without making a pig. Most are realistically 30-40miles. But if thats enough for you, lithium may be a wasted expense
Well, my longest common weekly ride is 20 miles, and it is getting more and more easy to find an electric car recharging station. Even without that, I could 'juice up' a bit for the ride back using a common mains plug, I guess. But maybe a better project for me would be a home made hybrid solution. I've had this idea of putting an electrical motor connected to the main engine belt (is that what it is called in english?) getting feedback for the ICE effort based on belt tension and going full throttle when the belt mechanical tension is above some threshold, or something like that. Do you have any experience in such a thing? I don't think there is a recharge station in my entire country. Is it cheaper than gas if you plug it in to the wall? .25cents USD a kwh where I'm at. I have no clue whatsoever as to the cost, but we now have a more or less general trend of having reserved parking places for EV on shopping centers and these have recharge plugs. And we have a lot of shopping centers... |

Does the hyundai have a manual or automatic gearbox? Manual is generally much easier to convert. It is doable, but the cost increases with vehicle size. Can you afford to spend 5 years fuel costs upfront? EVs are only cheaper in the long term, or if you salvage parts. I have been leaning more towards motorcycles and lighter vehicles recently because the lithium batteries are so expensive per kwh.
Manual gearbox. I know the costs are directly proportional to vehicle weight (does size really matter? ) and I would surely shop around for all the used parts I could find. Because I have the space, and since the net weight of the vehicle will force me into using a large motor to start with, I think it would be more cost effective to go for lead-acids instead of lithium and the like. I know the energy density is far from perfect but they are very easy to find and much cheaper. 5 years fuel cost? If you knew how many kms I drive per month you would probably come up with a different number... sure, I can do 5 years fuel cost, it's really not that much  But back to reality, is this at all doable? What kind of price would you see me paying for all the parts? How much labor to achieve the all electric goal? With that on my hand I can make an educated decision as to pursue this or not. |

I've thought about this multiple times now, but never quite bit the bullet... Do you think a first generation Hyundai Starex ( http://en.wikipedia.org/wiki/Hyundai_Satellite) would be a valid candidate for a conversion? I mean, the chassis is great, plenty of space and all, but the engine is very underpowered (at ~80HP) and it is not exactly cheap to drive. I've toyed with the idea of just scrapping the diesel engine and putting some large emotor, but there are a few oddities I don't know how to solve, like the assisted brakes and steering, as well as the A/C (which I really need). Would you consider this doable? What would it cost me to get your help in coming up with a viable plan and budget? |

In the bitcoin forum? really? Can't find any other place where GPU and $ are going together. Seen few posts that mining didn't exactly cover in some cases electricity bill for few next days, I know not everything is about money but in some cases could be better alternative than switch off so get this idea... and here we are Your logic is appealing, but at this moment wrong. You mention that a 5870 takes over 8 days to cover your needs for a single calculation, so you are not interested. You want 5970's which atm are the most efficient miner GPUs, so when people start turning off these cards you can rest assure the next difficulty step will make everyone go back to mining. But mining is a gamble, and you offer a somewhat more certain means of profit from the GPUs we all own and love, so I guess there will be people interested. Best of luck! |

Still hopeing to find some more persons with free GPUs.

I really had a bunch of funny remarks to make. I believe they would be witty and entertaining but how can one be sure? It turns out that one can end up being accused (*) of being an asshole more easily than not. I *really* have to work on my self control now  (*) - http://bitcointalk.org/index.php?topic=4505.msg68526#msg68526 |

I'm on the market for a 2.4Ghz Spektrum DSM2 transmitter, with at least 6 channels, and I'm willing to part with some bitcoins to buy it. I'd like to get a DX6i, DX7 or better transmitter or, as an alternative, a DM8 transmitter module (for Futaba, although I'll be putting that on an Hitec Optic 6). I don't need receivers or servos, but will also consider an offer with these. Any RC guys/gals out there looking to upgrade and make some bitcoins in the process? Make me an offer EDIT: shipping to Europe, so US based offers, while welcome, will be considered a last resort only. |

The token would just provide a Mathematical algorithm based one time password and that's it. The client would only send when it confirmed this password. You could use OATH for this.
It's open source etc. Like mentioned above you could still be vulnerable to someone swapping the address. You wouldn't lose your entire wallet though and would be a start.
It would be like this.
1)turn on client and enter address of recipient
2) type amount and hit send
3) client asks you for token password
4) enter pin on token get password ex:447421
5) type 447421 in to client and the transfer starts
If someone was listening in or standing over your shoulder etc they wouldn't be able to replicate this because they don't have the token.
The token could be used manually like this or it could be connected via usb / bluetooth / whatever they make a variety.
The client would have to be modified to get the "go" on the transfer from the token is all.
How does this protect one from the virus scenario? I'm assuming the wallet will have to be loaded in memory in an unencrypted way for this to work, at least while sending a transfer. And I don't know if this is an issue at all, but does this allow in any way for the mobility of the wallet? I mean, will the token and the wallet be paired in such a way that you can safely load your wallet into some bitcoin client, knowing that it will only be available if you use the token's OTP? |

I think (could be wrong here) that it's more complicated than it needs to be.
You could use a physically connected token or a bluetooth token (cell phone maybe?) with a pin on it.
You could do this several ways. One would be entering the password sends a code to the computer letting you transfer or the other would be it displays the code (like a paypal token) to be typed in on the computer and given access.
Theres a lot of options with tokens and seeing how you can have them pin restricted and how cheap they are I think it's a good option. My only issue is if the token dies / gets lost etc, you'd have to have a backup of some sort.
I don't get it, sorry. What would be stored in the token? And what would the communication between the token and the bitcoin PC client be? If you are using the token to hold the wallet and do the transaction signing itself, then we are talking about the same thing, if on different hw (pics can come out REAL cheap, too). But if you are saying the token pin protects the wallet.dat file, then there's no trojan/virus protection at all, I guess. Once you unlock it, the file is available to the computer, period. |

So what would the requirements be for such a device? The bitcoin software would still run on the PC, but instead of having the keys stored in the local wallet it would communicate with the device?
I can see myself getting a proof of concept going using a PIC32... would that be safe enough? The device would connect to the PC using USB but instead of providing a USB disk with the wallet, it would provide a serial interface or something alike that would allow the connected bitcon client to operate upon. So it would still be possible for a virus to take over the computer and ask the device to transfer whatever to wherever, but the serial API could use a password protection / encryption step to make this harder. And because the keys are NEVER shared with the outside world, one could also set up hard limits (no transaction larger than 100btc, for example) so it would be safe to use the device on public computers.
Would this be safe enough?

Even my jedi level mind game didn't work at all (saying I moved sell orders to $2 and actually moving them only slightly above 24hr high). It didn't move an inch!
So either this channel of communication is very ineffective, though I'm pretty sure it is, or there is a real market force driving bitcoin exchange rates... we're getting more and more mature, quite a satisfying realization I say!
