Step 2The Information and Power Flow
Building the helmet-cam is not very hard. It's a matter of getting all of the parts together, understanding what connections need to be made, and soldering it down.
Building the helmet-can becomes very hard if you incorrectly interpret the flow of information and power between the components, or if you solder poorly.
When you get all of your parts, assemble the system using the connectors that come with the parts. Particularly if you use all hoyttech parts the connectors should play nice.
+ Plug a battery pack into the camera, and the camera signal (a yellow RCA cable) into the yellow input of the camcorder's a/v cable.
+ Plug the microphone into a battery pack and the stereo audio signal (a red and a white pair of RCA cables) into the matching input of the camcorder's a'v cable.
+ Plug the LANC into the camera.
There is a design choice in this step. You will notice that the hoyt micrphone has two power lines: 12V in and 12V out cable. You may put the camera and the microphone on the same power line (and use a single battery pack). I put the two on seperate power so that I can take the microphone out of the system without disrupting the camera power or doing additional wiring. There may be more elegant ways of doing this, but it works fine.
Play with your sweet-new-setup! With the camcorder "off," you should be able to press the LANC controller and turn on the camera. Once the camera is on, press the LANC again to start recording. The LED on the LANC is green when "on" and not recording and red when "on" and recording. Holding the LANC control turns off the camera, this is indicated by a flashing red LED and then no power. The camcorder sometimes acts confused if you plug and unplug the LANC remote in while the camcorder is on. If you lose video feed, etc. while this happens, power cycle the camcorder.
