About

My name is Miroslav Kolinsky and I live near Prague in the Czech Republic. My day job is a security systems engineer. I fix and install cameras, proximity card readers and all the tech behind them.

Now I work as an electronics developer for a big company.

Electronics and all the technical stuff have always been my hobbies. I like to build and hack things. My earlier projects mainly involved stuff with Atmel’s AVR, but before Arduino!

Lately I discovered the world of RC models and the possibility of transmitting live video feed from a model. RC models are nice, but FPV makes them interesting for me. Without it, I would probably never become a modeller.

I spent numerous hours on the web, searching for ideas, inspiration and help. There are many great sites driven by individuals who kindly provide information and photographs about their projects. My goal is to create another site of this kind and help others.

    Hi!
    I’m interested in programming of LCD controller based on RTD2660. I have experience in small projects for STM32 using C++ before. I find source code on your website for RTD2660. Could I used it? Could you answer me for which model of controller board is this code? I want to use it as debug board.

      Yes, feel free to download it and use it. It is downloaded from some obscure Chinese site and I have no further information for it. I have managed to compile it, but resulting binary have not worked. Than I lost interest in that topic

    Hallo,

    i also need to edit the firmware of my PCB800099 and already got some source codes from different sites, but they are always edited. I’m looking for the default oem source code.

    Do you may have it or a link to where it can be downloaded?

    Best regards.

      Hi, I plan to write a little article about it with download links.
      So far I was able to compile sources for PCB800099, then create my own panel definition, compile again, load and it works. I have plenty of source codes downloaded from various depths of Chinese web.

        Hi Mirek,

        I’m also keen to hear more about the PBC800099 board. I’ve just ordered one and I already know that I might need an alternative firmware. Even thought my board is very likely going to be configured to match my LCD panel resolution I may want to connect the panel via LVDS header rather than via 50 pin TTL FPC. Also I’d like to get rid of VGA and AV1 input – ideally I’d like to swap swiftly between HDMI for main content and AV2 for reverse cam. Also someone managed to get rid of the blue screen and replace “NO SIGNAL” pop-up with custom logo. Quite a few things possible with this board if you know what and where in the sourcecode and how to compile it. And this is something I can’t get my head around right now. Any hint is highly appreciated!
        Thanks,
        Honza

          Hi,
          Yes, so much fun projects to work on and so little time. I plan to write short article about the firmware and how to compile it. I found yet another source code on shady site which already has mod to remove the blue screen. Unfortunately it is made from different code base. Actually mod is one line of code. But I have no idea where to put it in working source. I tried several places without success. Maybe you can try.

            Hi
            I really interested about this article, how to compile my own firmware. I have SXGA+ (1400×1050) panel and I can’t find any suitable binary form your collections. Can you consider to publish it or have you step forward and don’t want to return to this area?

    Zdar. Také mě hodně baví FPV a chtěl bych se zeptat, zda bys mi byl ochoten postavit RSSI antenna tracker na Arduino bázi, nebo cokoliv pro Tebe jednoduchého a funkčního, co nepotřebuje na palubě nic navíc a hledá podle nastaveného videokanálu. Prosím ozvi se mi na email. Předem díky.

    I am Raphael from Austria/Freistadt.
    Have a solarpower station and 16x280A LIfepo4 batteries on it…
    Also have a Xiaoxiang BMS (200A) with Bluetooth and (maybe an RS485)….
    Found your old project(kolins-cz/Smart-BMS-Bluetooth-ESP32) on Github and have one or two Questions… May you email me or chat via signal whatever? Many Thanks

      Hello Miroslav!
      I’m Andi.
      Me too, like Raphael, I’m interested in your Xiaoxiang BMS project. I gave it a try, but got only some values, the other are zero.
      Maybe I have a newer version on the BMS.
      My problem is, I do not understand fully, at this point, how it should work. Maybe you can give me a hint.
      Please mail me, if possible.

        Hello, sorry, I have working version in my ebike and I have not touched it for years. I have put my code to github and stopped developing it.
