"This looks amazing, I can't wait to get one for myself! Congrats to everyone involved in the development."

"Yes this was all done with on camera GPS. There is no issue between CHDK and camera GPS, but you won't be able to get 1 second between pictures. 2 seconds is the fastest we've gotten, but GPS shouldn't be a limiting factor in any case."

"@Matthew - it looks like the cost will be around $300-400 for large external filter glass for the NX1100 or similar cameras. I think we're going to hold off on that for the moment as I don't think there's enough interest to justify…"

"Are you looking at the color image or the black and white image? If the B&W, I'm not sure, it might be a setting. Mine just happened to be like that already. But 0-255 is the normal range of pixel values so take whatever number you get and…"

"Any idea why when I do that same thing I am still getting the values of 0-255 instead of -1 to 1 after using the single image NDVI option in the Photo Monitoring plugin?"

"Hi My tests on an SX260 showed, that the biggest performance impact came from my SD card. Once I switched to a 30 or 40MB/s SD card, I could shave off about 1 sec on the interval. What the exact transfer rate on the SD Card bus is probably depends…"

"Looks good. Will you sell the APS-C filter separately like your other ones? And was the Samsung NX1100 chosen for its spectral response or because of cost/dimensions/other factors?"

New NGB Filters and Higher Resolution Camera at Event 38

Posted on August 21, 2014 at 12:09pm 20 Comments

We've been hard at work improving our popular NGB filter glass over the summer and the latest design is finally in! This design cuts off higher wavelength NIR light around 770nm. That reduces the amount of light crossing over to the Green and Blue channels which are also sensitive to NIR light,…

Check this out if you're interested in adding thermal capability to your drone. The resolution is lower than FLIR, but the accuracy of the readings seem to be very high (0.2*F). From the Kickstarter Specs…

NDVI Post-Processing in Fiji

Posted on February 24, 2014 at 1:14pm 14 Comments

A lot of people have been asking me how we post-process imagery coming from one of our, or any other company's, NGB converted cameras. There's a very easy way to run this processing thanks to Fiji and the Photo Monitoring plugin by Ned Horning. I've just written up a quick getting started guide to this…

New, Higher Performance NDVI Converted Cameras

Posted on January 29, 2014 at 10:30am 22 Comments

Late last year we released our first version NDVI converted cameras using Schott BG3 filters. Using those filters we were able to generate pseudo NDVI images with a single camera, building off the work of the Public Lab project. After working…

Dear, good afternoon.

I bought the Skywalker E382 and I need your help.
Read all information http://event38.wikispaces.com page and follow the manual configuration.
I'm having trouble configuring Dragonlink 2 Long Range (433Mhz) UHF Tx and Rx System and RFD900 Radio Modems (900Mhz).
My setup for Skywalker E382 is as follows:
Skywalker E382 168mm.
ArduPilot Mega 2.6 Set (external compass).
Turnigy 9X 9cH (2.4Ghz) Transmitter w / Module & 8ch Receiver (Mode 2) (v2 Firmware).
My question is:
Do you have a manual, tutorial or video of equipment configuration? The frequencies of the equipment are correct? Do you have manual, tutorial or video installation of radio base station ground? Which types of antennas you use for radio base station ground?

Thank you.

Sincerely

Juliano Costa.
