Here I’m flying fpv with quanum set and Gopro hero 3 black instead off camera in set.

Video is shaky and has a lot off jello effect, because I used frame instad off gopro housing. If you are recording while using camera for fpv there is some lag, but you still can fly without any problems.

Video of testing mini quad-racer for 80 eur with fpv from hobbyking. We used naze 32 controller. It was very windy, but it flew nicely.

 

 

 

Here is video about mod you will need if you are flying with dji naza. You will 3 positions on chanel 6 to select flight modes. Original potentiometer is not good, because it switches modes and it is really hard to select mode.

Original has 10k potentiometer. So voltage is 3,3V between brown and orange wire. So dc current is 0.34 mA. So I calculated resistors. Schematic below.

I replaced him with 3 position switch and 4 trimer.  3 trimmers are 4,7kohm and 1 is 10 kohm.

You can buy naza m-lite with gps for 130 eur and upgrade it with this tool to 240 eur naza v2.

Both nazas have same hardware, but different firmware.You can also downgrade it to original firmware, so there is no problem with warranty.

Follow this instructions:

Tip:

When you try to upgrade it make sure you do not have skype or other messenger running in background on your pc. You will use naza v2 assistant after upgrade.

After some testing I’m very pleased with upgrade.

Time lapse with gopro

Since gopro battery offers you at most 3 hours of shooting in time lapse mode, you need to use external power supply to power up your cam. To do that you will need case with hole to connect mini usb cable, and external power suply.

I still wanted waterproof camera, because I want to shoot  pictures outside and even if it is raining.

First I drilled hole in case with step drill so I can plug in micro usb cable.

For external  power supply I  used 12v 9ah motorcycle pb battery. That would provide power to gopro for at least one week.

Because micro usb voltage is 5v I used car usb charger. So I soldered car plug, usefull so you can disconnect it.

I sealed hole with patafix.

Gopro hero 3 cracked housing

Last time when I was cleaning my gopro housing I realised that it is cracked.  I was real lucky that it is still waterproof after diving in the sea.

Strange thing is that I don’t know how this happend. I never dropped gopro on the floor or even was hit by something.  I had hero hd and I drove over with ATV  and it wasn’t cracked.

So maybe I don’t have luck or maybe aren’t new gopro housings as good as they were ni past.

So I contacted Gopro support and got this response:

All our gear is tested, so we know what it takes to crack and/or break
> them.
> In the case of the housing it could never crack just for lying around.
> Maybe someone used or dropped the housing without you noticing it?

Gopro claims that all their products are the best, so OK i knew from the start that I will need to buy new housing. But I’m not so sure anymore if Gopro is still as good and durable as it was.

Another thing that bothers me is very very poor baterry. It lasts hardly for hour if I don’t use the remote. But support said that they will send me new one. Nice!

 

So at the end I have still mixed feelings about Gopro. Competion is not as good as gopro. I like gopro camera and mounts, video quality is good. But I bought black edition (pro camera)  for 400 eur,  I want the best camera without excuses.
