I have made small multifunctional device for Aerial Photography and FPV use. I call it RC Camera Controll (RCCC). Could not find better name



RCCC has following features:

• RC Camera shutter control (Focus, Shutter and GoPro mode)
• Video source selection (switch one of 3 video inputs to video output)
• High current switch output (Turn On/Off LEDs …)
• LiPo battery low voltage alarm
• Sum PPM or 3 PWM input from RC receiver (Shutter, Video source, Switch)

It is small 23mm x 40mm (including connectors) board weighting approximately 8g with cable that combines 3 devices: Camera shutter, Video switch and High current switch. It is controlled with sum PPM or regular servo signals from RC receiver.

Shutter is compatible with GoPro HERO and HERO2, all C3 plug and 2.5mm plug Canon cameras, Nikon cameras and also many other cameras that have shutter connector.
I have tested GoPro HERO2, Canon 5D, Canon 600D, Nikon D5000.
(Shutter function with GoPro camera operates as On/Off switch. You must set GoPro to One Button mode to start recording when turned On)

Here is video where I tried to show all features of RCCC

Discussions and details in this thread.

Some time ago I started following Dennis Frie opensource DIY headtracker thread. Recently my friend bought Fatshark Dominator Goggles which have place to connect Headtracker module and idea came to me.

So I made this is small Arduino Nano board designed to fit in Dominators original headtracker place.
On top of that board you have to solder GY-85 IMU and it is ready to use. You can get IMU here:

To reduce cost and space it has no USB interface so you have to connect with FTDI adapter like this. (Like with Arduino Pro Mini)

This board uses Dominator HT button and buzzer. I have attached modified code where I have added buzzer support, and used it on startup and buton press.

Here is video where you can see it in operation:

DIY Headtracker for Fatshark Dominator goggles with GY-85 IMU (0 min 54 sec)

You can get one of these boards (green board without IMU) for 16$ + 4$ worldwide shipping.

They have preloaded Arduino bootloader and v0_08 software.
They have soldered small pin headers that plugs in Dominators.
You need to solder Arduino pin header (included) to upload new code or connect with configuration software. Also you need to solder IMU that is not included.

I sell these boards without IMU!

Steps needed to use DIY HT for Dominators:

• Get DIY HT Dominator board
• Get GY-85 IMU
• Get FTDI serial adarpter
• Solder together HT and IMU boards using pin headers and cut long pins left.
• Solder Arduino pin header
• Connect FTDI adapter to HT board and do configuration as in DIY HT thread
• Please be informed that TILT and ROLL axis are swapped because of different IMU orientation than original DIY HT. That doesn't affect HeadTracker performance.
• Connect RC transmitter to Dominator goggles (If making DIY cable for transmitter follow connector pinout attached)

Had good weather and tried new places to fly. Also found beautiful place at river.

I have made small circuit that I put in my radio that adds additional 2 channels to PPM stream that goes to FrSky module and now I can use all 8 channels.
I also added low battery warning and servo test function to this device.
