The 3D printed case houses a Lemaker HiKey board and a 650 mAh lithium-polymer battery pack.
While its 8-core, 64-bit ARM Cortex-A53 processor has more than enough power to run virtually any Android app on the market, it sports a unique party piece: it’s the official reference board of the Android Open Source Project. As a result, most of the HiKey’s necessary components are included directly in the AOSP source tree (a lifesaver). That said, getting my custom AOSP build to run successfully was still a tall order, requiring me to (among other things) recompile the kernel with performance-oriented tweaks to the USB driver.
A daemon called screenstreamer connects to the usbmuxd service, transmitting the screen’s contents to the iPhone and emulating touch events on the Android side.
