Transportable FPV System - Possible Build Idea

[kah00na]

I have been showing more and more people the awesomeness of FPV. Everyone is always interested but I don't really want them to fly/drive my vehicle and break it (and neither do they). Most do have their own vehicle but of course they don't have their own gear to try it. I do let them fly along with me using a second pair of goggles, but it is not the same thing as trying it yourself on your own vehicle. I'd like to put together a mini transportable FPV system. I'm thinking about something focused on being small and can be zip tied, double-sided foam taped, or held on with a velcro strap to a vehicle. These are some ideas I have for how it would work.
1. FatShark connector so it can get clean power from 2S, 3S, and 4S batteries
2. Voltage regulator to get the proper voltage
3. Micro Camera
4. Micro 5.8Ghz transmitter
5. Mount the whole thing on a small piece of balsa wood
6. Mounting zip tie, tape, strap
7. Try to keep the weight down around 30-40 grams if possible

Has anyone ever tried to make something like this? Does anyone have something like this?


===================================
Possible components
1. FatShark Filtered FPV Transmitter Power Supply (2S/3S/4S), 18g, 2S/3S/4S, $8.00
2. HobbyKing Micro UBEC 3A / 5v, 7.3g, 2S/3S/4S/5S, $3.77
3. Camera, 2g, 3.6-12v, $45.00
4. 200MW 5.8GHZ A/V TRANSMITTER, 2.2g, 3.3-5.5v, $31.00
5. Maybe 1"x3" piece, 2g (maybe)
6. Zip tie, tape, strap, 2g
7. Weight: 18 + 7.3 + 2 + 2.2 + 2 + 2 = 33.5g total, $87.77

Maybe include a simple velcro strap-on vibration isolation system. Maybe a simple 4 silicone ball tray system.

You might be on to something.

Every additional piece adds more weight but if it is a strong enough vehicle, it would make for a better first experience for new people.

I think the silicone ball in compression has taken the lead in the most low-cost, low mass, most compact method to lower the vibration frequency of the 600-3000KV motor and associated prop for the total isolated mass platform of 50-600g holding a camera.

The tightly curved ~3/32" steel cable works exceptionally well, but takes up quite a bit of volume.

Basically you are talking about an FPV POD, they are around for some time now, I think David made a version too.

Are you looking to build something like this:

Yes, but that looks like an expensive crash.

Yeah, kind of except that has full size components. I'm thinking more of something smaller and more easily movable from vehicle to vehicle. Maybe some day I'll put something together and upload some pictures.

Here is one... Bruce calls it an FPV Backpack.
