Thanks for testing the app, I'll put the function in next release in the near future.

have fun!

Re: EVILRemote shutter and time-lapse controller for Android mobile

I havn't actually got the IR transmitter to work yet on the phone, but the application does run. However i'm having trouble putting one together without a solder iron. Is this mock up acceptable? Or do they have to be soldered together?

Yes, I think it's acceptable. Just make sure you use a stereo cable, and leave the ground unconnected. Even you soldered the wrong pins, I think it won't damage your device.

Re: EVILRemote shutter and time-lapse controller for Android mobile

Ok I got a little skeptical as to whether or not my mock was working or not..so I decided to buy a soldering Iron and solder it up! Took some inspiration from cubie's design and this is what i came up with..

I'm not sure if im doing this right but this is what i do. I set the camera on manual mod and then change the shooting rate to "Remote CDR"

Then I run EVILremote and try to set off the camera, but it still doesnt work. Either the program doesn't work on galaxy s phones or my mock up is garbage hahaha.

BTW theres another program on the android market called PhoneIRmote and they're saying that their program is currently incompatible with galaxy s devices.

hi piinuts:

please try wearing a headphone and turn the volume up, you should be able to hear an IR noise sound when press 'shoot' button.

btw, you can also 'see' the IR light-up by facing the IR LED to a webcam or camcorder when you press the shoot button. That's the easy way to check whether your IR LED is working.

thanks,
jeffrey

Re: EVILRemote shutter and time-lapse controller for Android mobile

Yeaa I do hear a signal coming out when I play it through my headphones, but my camcorder doesn't pick up the infrared light. I guess the way i put my transmistter together. theres not much I could do wrong.. wondering what it is...

And I did make the LEDs polarized so I would have both neg/pos on one lead of the audio connecter.

Any ideas?

thanks

Phil

Please try connect the LEDs with a 1.5v AA battery, one of the LEDs will be light-up.

You might need to replace the LED and try again.

Alright im gonna give this another shot tomorrow. I'm going to be picking up these again http://www.radioshack.com/product/index.jsp?productId=2062565#pr-header-2062565 .

Just a question, could too much solder be a problem?

Re: EVILRemote shutter and time-lapse controller for Android mobile

I think iPod/mp3 player is more suited to the task. My guess is the audio amp in some phone are not good enough. It need to be able to do 18000hz signal, since most of the infared is in the 36000hz region. Also you may need to turn the volume up for range?

For time lapse the iPod is better too since it can last all day especially on mostly empty sound. Just record blank mp3/wave file for the duration you need and let it play shoot and blank repeatedly. Blank mp3 is easy to creat and very small due to compression.

Playlist of shoot, blank,blank..... To control duration using duration playlists.

I got it working now.. all it took was to max out the volume on my phone... Boy do i feel dumb now. Thanks Jeffrey Thanks Tuan

Re: EVILRemote shutter and time-lapse controller for Android mobile

Just curious, did you test what was the maximum range you could get? By that, I mean the distance between your IR transmitter to the camera. I was only able to get about 4 feet.

Re: EVILRemote shutter and time-lapse controller for Android mobile

Yea.. I could only about 4 feet also.

I know that for android phones there are custom firmwares that take off the volume limiter so you can possibly theoretically boost the IR signal that way. I've had some bad trouble with custom firmware in the past so i dont think i want to try it.

But for time lapses i am happy to have stumbled across this application.

again much thanks to Jeffrey

Re: EVILRemote shutter and time-lapse controller for Android mobile

congratulate it's working. I tried to set the output volume to maximum by default, but the Adobe Flash framework (Flex) that I use for coding seems not allowed to do that.

have fun!

My first time lapse done with NEX-5 and Jeff's EVILremote app. AGAIN MUCH PROPS for the awesome app.

I’ve updated the remote controller app for Android to version 1.1.0 with these features:

Timer settings will be kept between control modes.
Add a new “Long exposure time-lapse” mode.
Add a splash screen (i.e. the start-up screen.)

Here is the look of the splash screen with Escher's Droste effect:

The app and source code is available on my English website:

Re: EVILRemote shutter and time-lapse controller for Android mobile

Hi

first of all: great stuff

Question about the apk: is this flash based? for some reason it won't install on my ZTE blade and I know flash is not supported, that's why I'm asking.

I have built the transmitter and even using my laptop's output on the highest volume setting I'm only able to trigger the camera from a about 3 feet at best. No luck with my phone as it is obviously lower power.
How do you achieve more range (or at least get the phone to work as well)?

I think I might have bought IR LEDs that emitt less power than the usual, not sure though.
Can you tell me what exactly to look for?

Thanks
