HDMI Color Processing Board Used As An FPGA Dev Board To Mine Bitcoins

The blue board seen above is the guts of a product called the eeColor Color3. It was designed to act as a pass-through between your television and HDMI source device. It boasts the ability to adjust the color saturation to suit any viewing conditions. But [Taylor Killian] could care less about what the thing was made for, he tore it open and used the FPGA inside for his own purposes.

The obvious problem with this compared to a proper dev board is that the pins are not all broken out in a user-friendly way. But he got his hands on it for free after a mail-in-rebate (you might find one online for less than $10 if you’re lucky) and it’s got an Altera Cyclone IV chip with 30k (EP4CE30F23C6N) gates in it so he’s not complaining. The first project he took on with his new toy was to load up an open source Bitcoin mining program. The image above shows it grinding away at 15 megahashes per second while consuming only 2.5 watts. Not bad. Now he just needs to make a modular rack to hold a mining farm.

Playing Meat Boy On An FPGA

We usually look at these FPGA University projects and think how much fun it must have been to get credit for the work. But in this case we can’t image the grind it must have been to implement the game mechanics of Meat Boy in an FPGA. See how well it came out in the clip after the break.

Remember that with an FPGA you’re basically building hardware devices by using code. The Reddit discussion of the project sheds some light on where to start (and even shares the source code). The Altera DE2 is pushing the game to a monitor using SXGA at 60Hz. The map is laid out as a collection of 32×32 tiles, each represented by 2 bits in memory. [SkipToThe3nd] does go into detail about how the physics work but we can’t even begin to paraphrase that part of the discussion.

The game being cloned here is Meat Boy, the Flash game predecessor to Super Meat Boy. If you’ve never heard of the title we’d suggest watching Indie Game: The Movie, a documentary which follows several independent game developers as they try to get their titles to market.
