"Yes it is similar. Black plastic surfaces is better than metal because of better temperature balance (if you didn't touch before with warm hands.)Fortunately, Lepton lens is only 3mm diameter. So covering it a little bit easy. You can use any…"

"How do these handle flat field corrections? On the quarks you have to manually cover the lens as the image degrades to allow it to flat field and recalibrate itself. Is this the same with Lepton? "

"By any chance are you guys selling your breakout board? I have a lepton core module, but with the PureEngineering breakout board... So, your breakout is better suited to be implemented faster on a uav... "

FLIR Lepton vs Apple Facetime HD Camera

Hi Everyone,Yesterday, I shot this video with my MacBook Air and DroneThermal camera.The results are promising. Thermal image resolution is only 80x60 pixel but sensitivity is not bad.BTW, We designed an optional 3D printed (SLS) case for the camera. It looks better :)Shapeways.com has some difficulties in these days. We will share the 3D print files soon on our web site…See More

hello Melih,
My problem with Endurance-RC and their PCTx is that they didn't tell me the system would not work on my Futaba 6ex 2.4ghz radio, until AFTER I had bought it!

Are there some radios that your system will not work on?

Hi,

I'm using 6ex too :) I'm selling DT-3K headtracker since 8 months, and this device using same method for sending head tracking signals. No problem with all futaba, hitec, etc. I have happy 100+ customer :)

Melih, Can I use new 420 camera w 2.4ghz tx with OSD? is there video in/out pads?
And I would like to write code for USBtoPPM for Spectrum/JR head tracker.

Hi Mark,
Yes you can use it with OSD, camera have + - and video pads on bottomside.
Sorry about Compufly, offer finished now and i sent the products to winners. New products will on stocks in 1 week.

Hi Melih, I'm interested in getting a few units of USBtoPPM for Futaba. Wondering if you have C# code as example as I want to integrate it into my C# application.

Melih bey merhaba,

Forumu 1 haftadır takip ediyorum. Sizin epey bilgili olduğunuzu farkettim. Size birkaç sorum olacak. Benim trexc 700 bir helikopterim var. Bu helikopteri önceden belirlediğim bir profili uçurmak yada sinyal kesildiğinde en uygun yere indirmek gibi aklımda bir kaç proje var. Bu fikirlerden birinide tez olarak sunmayı düşünüyorum. Bunun için arduino gibi bir kart, sensörler ve gps modul gibi parçalara ihtiyacım var. Sonrasında da C ile biraz uğraşıp hazır kodlar üzerinde modifikasyonlar yapacağım gibi gözüküyor.

Size sorum ise bu kontrol kartın hangisi bana uygundur ve aparatları ile ilgili uygun diyata nereden alabilirim? Görüşmek üzere.
