This boxy monstrosity is big for a reason. It lets you play games on the original hardware of fifteen different gaming consoles. That’s right, we said original hardware. One of the main goals of Project Unity was to keep the stock equipment by making any type of emulation — hardware or otherwise — taboo. The size of the case is a function of how much stuff is actually crammed in there. But the final shape was dictated by the available opening in [Bacteria’s] living room entertainment center.
The video after the break walks us through each aspect of the build. We’re floored by the quote of 3,500 hours of build time. But as you get a look at the wiring-hell of each different module it’s easy to understand why it didn’t just build itself. One power supply and one controller make for the least complicated user experience possible. We already looked at a giant switching mechanism that selects one console at a time and the singular controller unit. But [Bacteria] has a lot of other tricks up his sleeve which make this gold mine of a hacking reference piece.

[FlorianH] has all kinds of new features to show off with this generation of his quadcopter project. Just about everything has seen an upgrade or some other kind of tweak since we looked in on the last version of the aircraft.
You’ll find some outdoor flight demo clips after the break. Right off the bat we’re impressed at the rock solid stability of the quadrotor while in flight. Even indoors the last version had a hint of a wobble as the control loop calculated stabilization. Here he borrowed some code from the open source Aeroquad project which helps account for this improvement. But the hardware choices lend a hand too. He moved from an ATmega32 up to an STM32F405RG processor. That’s an ARM chip which he programs using one of STM’s Discovery boards. The motors have all been upgraded as well (if you listen in the demo videos for both models you can hear a difference) and he redesigned the frame, which combines carbon tube with 3D printed parts to keep it light yet strong. The upgrade is every bit as impressive as the original build!

This is a project to keep in mind for the kids next Easter. It uses electronics to light up your eggs instead of dying them (translated).
The project still has one foot in the old tradition as it starts by blowing out the eggs. The larger hole on the bottom, which was used to evacuate the yoke an albumen, ends up being just the right size to insert an LED. You could simply hook these up to a battery and resistor, but [Rene] decided to add some functionality by hiding an Arduino board in the fake grass of the Easter basket. This way the way the RGB LEDs can glow, blink, and rotate through different colors. And the foil covered chocolate bunnies aren’t just for show. He wired them up to the I/O pins of the Arduino to use as a switch. When they’re both placed on the same piece of foil it completes the circuit and starts the light show. See for yourself in the clip after the jump.
Of course for the older kids you’re going to need something more complicated to keep their attention.
