Mark commented on Melih Karakelle's blog post How About Open Source?"I'm a little late to this discussion but the way I see it, your problem is that they didn't reference the developers when they copied your product. I can see how that could be frustrating. In my experience, hobbyking can be very…"
Ricky Curwood commented on Melih Karakelle's blog post How About Open Source?"I think you would feel better if you were to accept it as a done thing & get back to the real stuff you enjoy.

Eric Lewis commented on Melih Karakelle's blog post How About Open Source?"As mentioned already I feel that we all are willing to pay more for a higher quality product with support that is proven. I am not in the need of a LRS just yet but when I am i will indeed buy from you. Just hopefully there will be a mod for…"
Alp ÖZDEMİR commented on Melih Karakelle's blog post How About Open Source?"Melih, i think what you're going through is a part of the opensource curse. Hobbyking is a china /hk based company and they neglect almost all copyrights/patents whatsoever. nevertheless they also have franchise in countries(germany, usa etc.)…"
Bill Bonney commented on Melih Karakelle's blog post How About Open Source?"Copyright is considered a 'moral right', so you can, if you choose change the license for your hardware from CC-SA-3.0 to CC-SA-NC or other more restrictive license. Though I do wonder how much other than the PCB layout you can protect.…"
Melih Karakelle commented on Melih Karakelle's blog post How About Open Source?"@Max,I'm happy when i design something. I guess enough people knowing arduino and they can read the code and find better usages than me. In the current code you can add just a gyro and use your receiver as an MultiWii controller No need an…"
Max commented on Melih Karakelle's blog post How About Open Source?"@Melih
Maybe you can provide some kind of "service" to keep straying customers up to date with the project and get your returns that way?
Like you say its not about the money, but hey, you don't want to go the…"
Melih Karakelle commented on Melih Karakelle's blog post How About Open Source?"@Max,
Yes this is another important point. I guess i have to stop supporting the OpenLRS project but they do. Because I have only 50 customers but will be 1000+ OpenLRS user after HK release. Good news for me:One of the customers is the copier…"
Max commented on Melih Karakelle's blog post How About Open Source?"The other thing that sucks is that poor Melih will now potentially have to answer support queries for free to customers who spent their money elsewhere... Hell no, let them deal with HK's efficient support ;)"

Crasher commented on Melih Karakelle's blog post How About Open Source?"If you don't want it copied, don't open source it. If you want it freely available to the community only, find a suitable license.

kolin commented on Melih Karakelle's blog post How About Open Source?"Hobbyking is not first one to clone OpenLRS, these prototypes exist from May 2012. I did some improvements to Tx module, made it JR compatible. I also plan to change it to 868Mhz and then sell few pieces as…"

Yesterday HK released a video about their new 433Mhz LRS modules.
And i shocked. Because it is unauthorized copy of my OpenLRS !
OpenLRS is an Opensource RC and i'm the developer of that system.
Stop the video on …

Hi everyone,
Another blog post about OpenBee :)
Everyone asking about telemetry speed but i didnt answer this questions because of nature of RF telemetry.
RF telemetry speed depends more than one thing. I just take this video for showing unidirectional communication limits.
The limit depends FSK modulation frequency and RF bandwidth. We can…

Hi Guys,
OpenBee modules ready and in stocks today. I just tested Dennis Frie's spectrum analyzer firmware and software over OpenBee. It is working perfect!. The original code a part of OpenLRS RC Receivers and OpenBee using same RF module and pinouts with OpenLRS project, this is why the code working without any problem. :)
In this…

Hi Guys,
Today OpenBee boards arrived from PCB factory and i just tested them and working fine :)
It is including Arduino 16Mhz ProMini bootloader and you can upload the code directly over Arduino with USB to Xbee Adapters. No need an external FTDI board or something.…

ModeratorSgt Ric said… - 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 :)

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.

- 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.

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.
