Ground Station Progress
|Cut Video RX power cable in half, then added an EC3 connector|
|DC Power plugs for the portable DVD player|
Another note is that the video RX and DVD player both use 3.5mm 4-pole cables- which are very, very hard to find anywhere locally. These cables look just like headphone cables, but with an additional pole. MCM Electronics has a bunch of very reasonably priced cable options.
I have a composite video to SD card video recorder on order, also from MCM. This will be very nice for post flight (crash) analysis.

|Magnavox portable DVD player (from Craigslist, $20) connected to Video RX (upper center) and power panel (left). See the live video feed on the monitor!|
|Nice bonus- Video RX + DVD player on only pulls 0.8 amps. (with DVD battery removed) It'll run for plenty of time on standard size 3s LIPOs.|
|Where to mount the ground station? How about this sweet (and cheap) soft sided suitcase from IKEA!|
|A couple rivets and velcro should do nicely to hold all the ground station components in place.|
Quad-Copter FPV Progress
|Camera with wiring harness, before modifications|
|Video TX, before modification.|
|Home-Made connectors using "break away headers" - these were secured together using electrical tape once installed on the aircraft|
Next step, provide power for the video TX. Since this is going to be a very basic FPV setup with limited range and capabilities, I chose to save cost and weight and powered the video system from the main flight battery. A more robust route would be to use an additional battery pack. This particular camera and video TX like 12v DC, so the 11.1v 3s flight pack works just fine.
|Added additional JST connector to Quad power distribution board to power the camera and video TX|
