Re: Follow object

I understand how complicated it is for me to distinguish and follow a moving object (hence why I dont want to use a webcam for it), it just seems like a simple task to do. I think its too hard for me though. So unless someone has a simpler suggestion for me i think i will give up. Thanks anyway for ...

Re: Follow object

Ok this does have to fairly simple to program I'm not very experienced. A spinning antenna sounds much much simpler to program. Do you think it would be fast enough to follow a moving vehicle? What would be best to use to sense the angle the antenna is on at a given point? It seems like such a simpl...

Re: Follow object

Could anyone explain to me what the problem would be with a few directional antennas tracking the strongest signal. Seems to me (in my severely limited experience and knowledge) that a signal could be sent many time during the pass and the pi could constantly be comparing signal strength until it is...

Re: Follow object

What about utilizing a mobile phone?
Or a UHF radio?
Both are always carried when racing for recovery situations.

Re: Follow object

I definitely think a child is more expensive. Cheaper upfront but the cost to maintain it is ridiculous.
Our courses are mostly fairly open so shouldnt be a big problem.

Re: Follow object

Ok well I figured I wouldnt bother writing the whole thing about what im doing but i guess it will help. I race in off road racing and would like to get some footage at various places around tracks. I'd like to mount a go pro to a servo and have it point towards us as we go past (or alternatively a ...

Re: Follow object

Its basically to track a car as it drives past. It doesnt have to be very accurate (probably within 10 degrees) but it needs to be smooth and fast because its moving about 200km/h. Will be in line of sight when it needs to be tracked but i think camera tracking is over my head.

Re: Follow object

Should have been more clear. It must be wireless and be able to track a fast moving object. I am confident i can build the physical linkages and frame and do the wiring etc, i am not confident in the programming of it. You have given me two seemingly good ideas. One is a GPS chip on both and compare...

Follow object

Hi. I am trying to make a device which will always point to a small beacon up to 200m away. So for example if i have this beacon in my pocket then the device will point towards me no matter where I walk. I have a raspberry pi which i would like to use for this. I am confident i can build the physica...

Sonos replacement

Hi. We are currently building a new house and was looking at installing sonos. But with at least 5 zones the cost is excessive. I have been wanting a Raspberry Pi project which is useful to me for a few weeks now and thought this could be a possibility. My requirements for this system are: A NAS wit...
