I tried and unfortunately I found out it doesn't run on Linux. To begin with, no extra plug-ins beside the original ones are selectable. And the other big problem: even for these nothing is shown on the USB board, the application also doesn't show any error message that would give me a hint on where to search for the problem.
As the host program is not my software I cannot do anything about that, sorry 

Yepyep...went immediately into my browser favs. Good one 

Maybe you can add more exchanges and different currencies? Also it would be great if I could add my own exchange (basically just a text label and the current buy and sell rate). Then this should go into the list and be compared to all others. This way even exchanges currently unsupported by your calculator could be considered.

Variants 3 and 6 are my favorites <3

I've been observing that strong wall at $150 for quite some time now and when I thought we could not climb over it for a long time it just happened...

I think (and hope) it will reach $200 before the end of the year, total trade volume still isn't big compared to other markets. Everything that is necessary for a big climb is a big buyer who suddenly enters the game. I'd say the chance is 50:50.

The only thing a video could show better than a picture is the animation. But it is really only a simple and boring vertical scroll animation, maybe you are expecting a little too much here. You won't put this on your desk and watch it instead of a movie (except you are incredibly excited about the exchange rate anyway  ). So right now I think I am too lazy to do a video for just that. Also there are videos of such message boards on Youtube already, just search them.

The base program (and therefore also my plug-in) is based on .NET which means it should be possible to run it using the Mono framework on Linux as well as a Mac. However, I haven't tried, so far I only tested it on Windows.
A quick search came up with this so apparently it is possible to run Mono on a Raspberry PI though I think it's a lot of overhead for the poor small thing. Also it is a GUI application so you will need to run a desktop environment on it.
Regardless of that if I find the time I will do a test with my board on Linux and report the results here.

I wanted to have a BTC exchange rate ticker on my desk that I can also see when I am not using my computer and the screens went into power safe mode (of course the computer itself has to be running). I found and bought a cheap programmable USB LED display which I thought could fit the purpose, the Dream Cheeky LED Message Board.
The default software is fun to play around with but as I needed something that is obviously not part of the default package I searched how I could use it with my own code and found an alternate driver for it written in C# that has support for plug-ins. I wrote the plug-in and use it for myself but I thought it makes sense to share it for other BTC nerds like me out there.



Features

• Works for various fiat currencies and can easily be extended to support more (basically every ticker that Mt.Gox provides)
• Shows the last trade price in a given fiat currency, updated every 5 seconds
• A change in price is shown by an animation: the new price scrolls in from above if it is a higher price or from below of it's a lower price than the last
• Refresh rate is configurable, animations can be disabled
• Uses as much as possible of the display area, for smaller numbers more fractional digits are shown
• Automatically rounds the number so that it fits the display

Prerequisites
To use this plug-in you need the Dream Cheeky LED Message Board. I am not related to Dream Cheeky in anyway and won't be able to give you any support for the hardware itself or answer questions about where to buy it.
Furthermore you need this alternative USB LED driver. Again I am not related to the developer of this software and cannot give you any support for it.

Download and usage
View Source
Download
The proposed file extension for the download is .txt - you need to change this to .cs so that the resulting file name is coynzer.BTCTicker.cs and save the file to the same folder where the LedMatrixDriverApp.exe from the alternative driver is. Afterwards start the USB LED Driver software (or if it is already running click the "Reload" button) and you should see new BTCTicker entries for various currencies.

Support
I wrote this for myself and don't plan on doing full-time support here. But of course I might be willing to answer questions (just ask) and if you find problems and report them I probably want to fix them and provide an the updated version.
Also feel free to extend the plug-in and post your improvement here, if I like it I will link to your modified version from the main post.

I noticed the same and I even got some on Cryptsy in trade for BTC when the rate was 0.025 - seemed cheap. Well, now it is as 0.015 so it doesn't look like my most clever move. Nevertheless I believe there will certainly be at least one Scrypt based coin with bigger success in the future and Litecoin is still a promising candidate. Having a good ATI card that is no longer profitable for BTC anyway I think it makes sense to use it for mining Scrypt coins. Right now I am simply trying to get a share of every Scrypt coin that is traded somewhere, every 24 hours a different coin. You never know, and I don't want to have to regret something again 

Sure, but it's a whole different story if you have talked it through with someone and made an active (and wrong) decision about it at a time where it would have really been worth to buy them. Compared to people who just learned about it too late and now regret not to have heard about it earlier.

I read about Bitcoins somewhere on the Internet back when 1 BTC was $1.50. I started mining it, mostly out of pure technical curiosity, I just wanted to see it in action. After getting involved and having my wallet filled up a bit I started to think whether this could be an asset for the future and I should buy some, as mining with my CPU already wasn't really worthwhile anymore at that time. Talked it through with my girl, but our financial situation wasn't very good at that time and the maximum 1500$ we could have spent on it didn't seem to be much compared to what I knew about traditional investments. So we decided not to.

I stopped mining too and even completely forgot about BTC when I reinstalled my computer...without making a backup of my wallet.

Bitcoin got my attention again when the bubble started to grow this year and it was at $200. I remembered by decision about not buying the ~1000 BTC which would have been worth $200,000 (and still $140,000 today).

So what's your story for the Regret Thread? Maybe you have told it elsewhere already but please put it here, where it really belongs to  

When I saw the thread title I thought it's just another "lost my wallet" or "lost my wallet password" thread which are usually hopeless and the "SOLVED" tag just indicates that the user has been explained to how he cannot get his BTC back and accepted his fortune.
But surprise, surprise!

I am really happy for you that it came out like this. Reading this story made my day a bit brighter!
