[CNLohr]‘s Microscope Slide Linux AVR Minecraft… thing

avr

We’ve been following [CNLohr]‘s process of creating an AVR-powered microscope slide running Linux and interfacing redstone circuits in Minecraft to real world electronic for a while now, but we’re really at a loss for words on how it works. Well, now there’s a video explaining everything you want to know about this amazingly complicated and overwrought thing.

The device is powered by an AVR microcontroller and Ethernet controller running [Fabrice Bellard]‘s JSLinux in a browser. [CNLohr] added a few bits to JSLinux allowing him map the x86 IO ports emulated inside JSLinux to the AVR’s IO ports. This allows him to query the status – both analog and digital – using just a browser. Very cool, but [CNLohr] can also run his Minecraft server optimized for 8-bit devices on this microscope slide server to create a bridge between real electronics and redstone circuits.

To sum up what’s going on here, [Bellard] created an x86 emulator in JavaScript, and put Linux on it. [CNLohr] is serving this from a microcontroller attached to a circuit built on a microscope slide so he can blink an LED from within Minecraft. It’s the most beautifully over engineered and useless thing we’ve ever seen, basically.

In the video after the break, you can see [CNLohr]‘s overly convoluted walk through of what’s going on with this microscope slide server. As a little bonus, you can also catch a glimpse of Hackaday at 00:20 in [CNLohr]‘s most visited / new tab thingy in Firefox. We’re honored, really.
