So, it’s been a while since i’ve documented any progress on this nice little project. This is my attempt to do so 
- Main Platform
I scored an IGEPv2 some time ago and been playing with it (a lot!)
Working:- Gentoo (100% updated, running ISEE’s kernel)
- Bluetooth
This allows me to connect to my BT GPS module (rfcomm), BT keyboard (with regular HID support) and WiiMote (with libcwiid) - Wireless
Although there is no Monitor mode it seems
So i’m using a USB ZD1211 module for kismet - Sound (perfectly supported by ALSA)
Not Working :
- Video Output
I’ve added the SVideo connector as by direction of ISEE but their kernel has no support for this.
My current efforts have been unfruitful, but the future looks bright
- Power Platform
Still building this but ordered some parts already :- Cells
Going to (probably) be 6 18650 3.7V 2500mAh protected cells run in a 3S2P setup to give me 11.1V at 5000mAh - Charger
I’ve been playing with the MAX1811 that I sampled some time ago, and am now able to use this to charge one cell reliably.
Looking into making a true BMS around an Arduino and some PWM switched Buck convertor to charge these 3 cells.
(Also looking at just skipping this step and buying some premade 3 cell charger) - 5V DC-DC
After joining ##electronics again, I quickly got some help finding the supreme part for this platform.
DPCAV has this excellent module which will fit my purpose perfectly.
- Cells
- Interfaces
I would like to use my HMD for this project, but as video is not working I’ve ordered a Nokia 3310 LCD on PCB from nuelectronics. This screen has a simple SPI interface, which I can directly interface with the IGEPv2 through a level shifter.
The PCB also has some buttons, but I’ll probably end up using the wiimote as buttons for this display.
- Case
I really need to start looking at packaging all this….
