EVILRemote shutter and time-lapse controller for Android mobile
Jul 7, 2011

Hi,

I'm working on an Android mobile phone project for my LEGO IR Remote Controller ( http://forums.dpreview.com/forums/readflat.asp?forum=1042&message=37686974 )

I'll make it free and maybe open source code, and it could be easily converted/compiled to iOS and BlackBerry platform. Currently, this app support Sony NEX-5 camera only.

It's almost finished, here is how the app looks:

Have fun with your NEX-5

excellent! I've been waiting for this. do you have a url to the IR controller construction offhand?

being an android user, I've been absolutely dying for one to come out (after watching a couple iOS versions being released).

from your screenshots, it looks simple, clean and rather nice!

Looks good! There's a similar iOS app which uses the headphone jack as an IR transmitter. Looking forward to trying this on my android phone.

Yes. Actually, I provided him the NEX-5 IR signal sound wave source files for normal shoot and 2 seconds delay shoot, which are available at this post:

Amazing you can get the proper ir pulses through a waveform file. Never even occured to me in the past, but makes perfect sense.

Time to warm up the soldering iron...

Please keep us posted on the status of your app.

I've upload EVILRemote.apk file and the source code on my English blog:

http://swf.com.tw/en/open-source-camera-ir-shutter-and-time-lapse-controller-for-android-smartphones/

I'll upload it to one of the Android Markets later. This app doesn't support all Android smartphones (sorry!). I only tested in these phones:

  • HTC Desire

  • HTC Desire HD

  • Sony Ericsson Xperia PLAY

  • LG Optimus Black P970

thanks and have fun with your Sony NEX 5 camera

Thanks for the good work, and for posting schematics!

Since I'm a total idiot with EE stuff, would you mind giving some details of the exact part list for building the physical transmitter? I do have a soldering iron... but I'll need a shopping list to take to the local radioshack to get the parts.

I can't wait!

This is a good idea for a remote maybe, but not very practical for time-lapse.

You gonna leave your phone by your camera the 8-12 hours you want to do a time-lapse photo shoot? phone turned on? away from you?

Anyway, remote time-lapse devices are cheap, easy and practical to use. check this one: http://tempus.bymac.org

practical or not, I guess the fun in a DIY project is the act of doing it and the sense of accomplishment. BTW, I found cubie's other blog post that details the steps of building the transmitter:

http://swf.com.tw/en/create-a-lego-ir-remote-transmitter-with-headphone-jack-for-sony-nex-5/

Instead of using a cable to connect the phone and the transmitter, I think I'll build simpler one so I can just plug into the phone and point to the camera. Cubie, did you put the transmitter right by the camera because of weakness in signal?

Hi Cubie,

So I tried it out and couldn't get it to work. I'm guessing that it's because my hardware wasn't working. However, just doublecheck, if I use the app without plugging in the headset jack, am I suppose to hear something through the phone speaker?

I tried it without my transmitter plugged in, and I wasn't able to hear any sound. I'm on a HTC Vision with Cyanogenmod 7.

Thanks.

Hi Mac,

I'll try to make an IR controller using Arduino-alike board or PIC 12F629 microprocessor later this year, thanks!

Hi Hosermage:

The IR sound won't come out to speaker, you have to use headphone to hear it. Please let me know the result.

thanks,
jeffrey

True! DIY Rulez!
I just dont think you will be able to use it as an intervalometer.

For a 8h shoot Your phone will run out of battery because it is always on. or you'll get a call in the midle of the shooting. or you want to leave the camera shoothing you long hours, but you need to take your phone back with you.

And to use it as a remote is a great idea. but you still need additional hardware :S You're better of luggin arround one of those tiny 4$ chinese remotes. Too bad phones dont come with IR nomoore. Well.. even when they had IR, you could ony work with it for a couple of meeters :S

But.. For proof of concept: great idea!

We all like concept cars too. but there is a reason they don come out to the real word
Cool

Hey cubie, I was wrong! It's working! One thing I didn't know I had to do was to set the drive mode of the camera to IR remote. I just saw it while exploring the menus and setup and decided to set it at IR mode and give it another shot... lo and behold, it worked! See attached gallery photo.

However, the range of the remote left something to be desired. I was only able to control it from at most 4 feet away. I noticed that on the remote where I took the IR LED from, it was set about an inch apart. Do you think I can increase the range if I set them wider apart?

Thank you for developing such a program, I've been wishing for something like this. I can confirm that it installs and runs properly on my Samsung Epic 4g.

Your design is very clean and simple! Major props to you!

Will be possible in the future to add long exposures + time lapse together for night shots in the application?

Again

Thank you Jeffrey

Glad to hear it's working Your IR transmitter looks very nice.

Yes, the IR range is short, that's why I use LEGO to make a holder for the transmitter ;-p

I tried smaller IR LEDs which consume less power (I guess, because I don't have the datasheet), so their range is longer than normal IR LEDs under same power condition.

have fun!
