I am currently working on tapping power from my I1 to power my Tau2 640.
A couple of points to consider:
- the VPC has two ports: analog video and micro USB (mu). The mu supplies the 5v necessary to power the camera. The analog video out can be used to input into your 5.8 Tx. You cannot get live video out of the USB, at least without adding on some significant onboard processing.
- with the VPC, you can plug the mu into your PC (not Mac) and adjust the Tau's settings via FLIR's GUI. Within the GUI you can select different user templates for colorized outputs.
- once you're done/bored playing the VPC, you want to to eventually get the wearsaver board. Here you can solder your 5v and video out wires thereby making your overall package more compact.
- make sure you get a good voltage reg. You want to be sure the FLIR is getting a good 5v input. Don't speed thousands and then go cheap on voltage supply!
- I worked together with the folks at MARS (parachutes) to design and 3d print a bracket.
- as for power supply, I am tempted to get a stand alone lipo to power the FLIR + Tx. That is where I am at now.
- for recording, since the output is analog 640, I can use Elgato's Video recorder and I just save the videos to my MacBook Pro.
