[XVortex] pulled off a pretty incredible firmware hack. He managed to get a firmware upgrade for Synology running on a QNAP machine. These are both Network Attached Storage devices, but apparently the Synology firmware is better than what QNAP supplies with their offerings.
The nice thing is that this is not a one-off hack. You can download the raw image and give it a spin for yourself. A few words of warning though. It will only work on models which use the Atom and ICH9R chipset, you’re out of luck if you have one sporting an ARM processor. You will also need to format the drives once the new firmware is flashed so do this before you fill them up.
This harkens back to the days when DD-WRT was first being run on Linksys routers. We don’t remember if that started with upgrade image hacks like this one uses, or if the source code was available (Linksys was compelled to release it once it was proven they were in violation of the GPL).
See a proof video of this hack after the break.

What does dry ice, ethonal, wax beads, and a blender have in common? It was the first attempts at making media for this wax 3D printer that [Andreas] has been building up. Wanting to produce 3D printed objects out of metal, and finding that direct metal laser sintering machines were still out of reach of reason, he set out to find a different way.
After trying a few different methods of making the powdered wax himself, he decided that it was much more time effective to just buy the stuff. Using the commercially available powered wax mixed with activated carbon, and a custom printer, the wax is blasted with a moderately high powered laser. More wax powder is applied over the freshly sintered layer, and the 3d part is built upwards. Once he has the part in wax, he can then make a mold of it and cast metal using the Lost Wax Casting method.
While the quality is not perfect, and you still need a roughly 2500$ laser setup (which was borrowed from his school) its surely a step into the future.
Join us after the break for a quick video.

This fractal viewer is a great way to get your feet wet with Field-Programmable Gate Arrays. The project will give you some experience working with video output, user input, and a whole bunch of math and memory management. [Hamster] built it using the Papilio Plus board which hosts a Spartan 6 FPGA. This continues his odyssey into the realm of hardware design; part of which we looked at back in December.
The arcade Megawing for the dev board gives him easy access to the controls needed to scroll and zoom on the fractal design. Calculations to generate the shape are being run at 240 MHz, with the VGA output running at 80 MHz. The device has enough horse power and SRAM to show an 800×600 pixel output with a 60 Hz refresh rate.
We really liked the logic diagram that [Hamster] drew up when planning how the calculations would be handled. It’s not overly complex, but it took us a while to conceptualize how everything fits together. It’s certainly an improvement from his last attempt as we couldn’t make heads or tails out of that flow chart.
If you’re just interested in the pretty shapes and colors there’s a demo embedded after the break.
