Turnigy 9x - Frsky DHT Module Telemetry Hack without RS232 Converter

I'm having this transmitter for quite so long which i bought from a friend. All this while it just been used by my son to control his RC Rover as i don't trust the stock Tx module on the transmitter for my flying. Until i build my tricopter and then my quadcopter. Flying a multirotor need us to be aware of the on board voltage while flying to a void any mishaps.
As i have done a mod to a friends Flysky TH9x with a Frsky module giving him a means to monitor his voltage on board through telemetry, i decided to mod my Turnigy to do the same but this time using a Frsky DHT DIY module.

My DIY Spider Quad

Here is my first quadcopter build. I love how the TBS Discovery looks in the air, but i can't justified it cost for me to get one. And there is Reptile frame which also looks nice in the air but again it still cost a lot for me. Then i started to look for a free plans of a TBS look a like on the internet with which i could build one for myself.
Lucky me i did find it here -http://www.rcgroups.com/forums/showthread.php?t=1706111. Nick_P don't just share his plan of a spider quad for free but included a complete guide how to make one yourself in writings and a series of youtube videos.
Here is what i come out with...

Martinez V3 Brushless Gimbal for GoPro Hero3

Helping a friend with his brushless gimbals controller is quite an interesting experience. The board came with pin headers not yet soldered to it place. Searching the internet for information regarding how to connect and how to setup the gimbals itself is a challenge. But i managed at the end to get the right settings for used with a GoPro Hero3 on board. For a new technology, brushless gimbals has come to the point where every one can have a great stable aerial videos.

I am not going for the detail step, but just sharing what i've done.
