Three Announcements

1. We Are Shipping

2. Color Metering

3. App Screenshot

Seven pallets of Luxis turned up yesterday. They didn’t fit through the door so we had to unload them on the street and stack ‘em (gently) in the lobby. Look, I Instagrammed it:

Some of you will start getting your Luxis before this week is over. The rest of you will get them over the next week or so.

I’ve hired a couple extra stamp-lickers to speed things along.

In other news, we’re hard at work on the Luxi App, which we’re planning to release in September.

We’re attempting to add accurate color-metering functionality, as well as the exposure settings you’re expecting. Here’s a screenshot of the app in development.

Once more with feeling: Thank you all very much for your support and patience. We’re almost done.

Right, I gotta run to the post office...

P.S. A new Luxi Version of Pocket Light Meter App will appear in the App Store in the next few days too. Our heartfelt thanks to the developers of PLM for supporting Luxi.

      I became a backer for this project in April 2013. It's almost a year now but still have not received the meter.
      Am I alone here? I'm in Hong Kong. :(

    2. Creator Brett Crockford on September 15, 2013

      Thanks, finally received my Luxi ... Pity it took so long as my phone has moved on and the Luxi now resides in the bottom of my bin .... Hopefully there is a next time for you and hopefully you do it a little better ....

      The App: please, please talk to an UI/UX designer first, and also with a pro-photographer.
      First and foremost come the dials / adjustments. In your image, they use less than 5% of your screen real estate. Make it larger. Much larger. Secondly, what I am interested in are the readings of EV, EV100, LUX, color. Again: larger, much larger font is needed. Do not design this in photoshop!!! Just copy some real luximeter / exposimeter and the results will be almost perfect. Otherwise, people might get unsatisfied. Please, remove the ads. Thank you.

      28.Aug. I received it in Taiwan.
      I'm looking forward to the APP, in which the illuminance values (Lux) are shown.
      That is the reason why I wanted to have the LUXI.

      The current version of the APP for me is completly useless (i'm no photographer).
      Thus for me the Lux should be displayed much bigger similar to Color and color temperature.
      To give the Color in CIE 1976 (u'v') or CIE 1932 (x,y) coordinates would work best for me.
      Ideally of course with color and illuminance calibration option.
      Thanks so far for your efforts.

      Email from 2013-AUG-7 "Some of you will start getting your Luxis before this week is over. The rest of you will get them over the next week or so." ... I think the "or so" part is important here. Any news on expected shipping dates for shipments to over-seas ?

    13. Creator 德源 on August 24, 2013

      Yet to receive this after such a long wait. Puts me off kickstarter.

    14. Creator Jonathan Wong on August 24, 2013

    19. Creator David Richards on August 23, 2013

      Due to such slooooow progress, this device is now out of date before it is even shipped... and STILL no sign of it even though shipping has been promised several times. It's practices like this that put me right off kickstarter :-(

    43. Creator Tarik SYkes on August 10, 2013

      Got mine today!! YAY!!!

    44. Creator Michael Richmond on August 10, 2013

      Received in Mountain View, CA. The Luxi looks well made and it's simple to use with the Pocket Light Meter app.

      I've noticed the calibration settings in the app. How important is it to calibrate? (I assume this is to accomodate manufacturing variability.) Do you have any recommendations for the best way to calibrate the app with the Luxi? I'm thinking of using it beside my Gossen meter in a few different lighting conditions and calibrate until the both the iPhone and the Gossen meter are showing similar exposure settings.

    45. Creator Richard Wilkins Jr. on August 9, 2013

      Just got mine! Cant wait to start using it!!!

    46. Creator Marc Anthony on August 9, 2013

    49. Creator Scott Watkins on August 7, 2013

      I ordered the iPhone 4S version, but since have upgraded to the iPhone 5. Would anyone like to buy my iPhone 4S Luxi?

      In another, extremely related, topic... Is there any way to get an iPhone 5 version without waiting until they go on sale?

    50. Creator Tom Tang on August 6, 2013

      Good news
      I am looking forward to getting the product
