More equipment details

The frequencies covered by my transmitter receiver combo are as below. Guess I will stay away from the band around 1200MHz as this is a harmonic of 2400, which currently is what I use in my radio.

Per a friend’s suggestion, I will also need to make an LC filter so that I do not get noise from the speed controller on my video.  Here is a link explaining how to make your own.

After making an LC filter, all that is left is to assemble some kind of platform for all the gear that can be easily attached on the back of my tried, trusted and nearly indestructible plastic glider and then I should be able to do my first flight this week-end!

The channels and their frequencies:

  • CH4:1080MHZ
  • CH5:1120MHZ
  • CH6:1160MHZ
  • CH7:1200MHZ
  • CH8:1240MHZ
  • CHd:1258MHZ
  • CH9:1280MHZ
  • CHH:1320MHZ
  • CHC:1360MHZ

First batch of Equipment

I feel like a kid in Christmas! The first phase of equipment has arrived.

All I need to figure out now, is how everything fits together. At first glance, it doesn’t seem to complicated. The most challenging bit will be cutting a few wires and a bit of solder here and there, and then we SHOULD be good to go!

Short update : got everything wired up and working on my laptop. DVR software also working fine.

Map Knitter

This piece of software may come in handy later should I ever explore aerial photography with my FPV drone.  It basically takes multiple pictures taken and knits them together.

Not sure how well it works, or how good fit it will be for my needs, but something to keep in mind.

Web site here.

It’s open source, so you can publish your own web site by getting the code here.

More info on so called “grassroots mapping” can also be found here.

A reportedly good book about aerial mapping can be found here.

Another open source aerial mapping software suite is Palentier which can be found here.

Project kickoff

This is my project to build an eye in the sky style FPV (First Person View) RC (Radio Controlled) drone. Not purely FPV, but with obvious FPV elements the ideal goals of this project is as follows:

1. Very good loiter time (1 to 2 hours).
2. Medium range (3 – 5km)
3. Pan / Tilt system for training the camera on a point of interest.
4. Waypoint and orbit functionality, leaving the pilot’s concentration on operating the camera and not flying the plane at those times.

Having read up a lot on the forums over at http://fpvlab.com, I see three emerging patterns that I will try to adhere to:
1. Get good equipment from the start.
2. Keep it as simple as possible.
3. Start by crawling, before running!

Goal #1 – get basic FPV up and running:
My first goal in adherence to #3 above, is to get very basic FPV going. The plane will still be flown within visual range as a basic RC plane, with the FPV being recorded on a laptop. Basic FPV flight may be attempted but always with a second pilot that acts as spotter and that can take over control via a buddy box setup if needed. Plane will be flown in normal RC range at all times.

This will give me a feel for FPV and “get my feet wet”. The gear will be installed in one of my existing foamie planes as a start.

Gear planned for this phase:
1. 900MHz-1.3Ghz Receiver SAW w/1258 Custom RMRC Version
2. EzCAP PC Based capture software.
3. 400mW 1300MHz Transmitter – NEW CUSTOM READYMADERC INTL VERSION
4. PZ0420 Camera
5. Self built ibCrazy antennas (probably cloverleaf – optional for this stage).
6. Pan and tilt (optional and if everything goes well).
