installed remzibi OSD on Vista x64.  Tried to do Serial Setup without success.  Used DIY drones FTDI cable to connect to DIY drones board (no other pins connected to anything), performed connect to COM23, then (per instructions) hold down SW1 while connect 4 wires of DIY cable to DIY board, then released SW1. Pressed "Start Test" and after 15sec got "Failed:OSD didn't not respond. Outbound Messages= R and Inbound Messages= Data Read: Failed"    

Saw same behavior after a few tries.  Tried RESET and then repeat, but no joy.

Any ideas what I'm doing wrong  (I hate to give up !  this thing would be GREAT if I could get it to work! )

Patience prevails (thanks to Paul and his detailed blog )

 The DIY remzibi OSD board only powers up when you provide the +12V and GND to (the 2 pins near the top of the image above).   To put the board in programming mode (to demo that "Serial Cable Setup" works), I did as follows:

1) install and run remzibi OSD by running setup.exe from the above site

2) connect DIY drones FTDI cable (the 4 wire one that shipped with the board) to (TX,RX,5V,GND) with black wire to GND :-),  and identify and Connect to the COM port (appears in Device manager under Ports(COM & LPT)

3) hold down SW1 on the DIY board and then apply 12V power to the board (the blue LED will come on)

4) when you release SW1, you are in programming mode, and can continue with the wonderfully detailed instructions on the URL above.   

5) Pressing "Start Test" on the Serial Cable Setup tab produced a nice green "Passed (Firmware Version 1.75)  which I liked much better than the old red "Failed: OSD did not respond"  (it could't before; the ATmega32A processor was brain dead from no power :-P )

I hope these details may help save some of you the frustration and delay of having to reverse engineer your own DIY drones board.    Happy flying (and try to land with the greasy side down as they say in flight school.)

Hi all,

I bought this board and i'm very disappointed with it :(

I tried to use to use the Mediatek GPS with normal and older firmwares, and it didn't work. (BTW, i just noticed now  an update on the diydrones store, a firmware is provided to update the GPS to work with Remzibi OSD 3DR).

Some issues i found:

- It shows numbers in the whole screen.

- Screen moves and offsets its position.

- After 10~20 seconds it shows glitches and mixed up characters all over the screen and it shows again the whole screen with numbers.

Anyone had this issues? 

One other thing was how to connect the board to the remzibi OSD software, after more that 2 days i finally got it to connect.

I was also able to update firmware using megaload at 38400 baud rate, but now the blue led does not power anymore, and OSD does not work, i only see intro message with firmware version and no GPS detection.


I updated mine and now it does not work anymore.

Can anyone help me with it, or can anyone from DIYDRONES provide the 1.75 firmware that comes with the board.

This is with Firmware 1.75 and it seems to work well.

Now I have to test with different GPS receivers.


Comment by guillesan on March 21, 2012 at 3:24pm

Indeed, the problem I have is that I mistakenly tried to change the firmware, and now the OSD does not work then and learned that the 1.75 firmware is specific to this Remzibi 3DR.
What I really need is the 1.75 firmware to restore to the initial situation the team, now will not turn on anything, not the blue LED, would appreciate if someone can give me this firmware.

Thanks to Diydrones service that provided me the 1.75 firmware is already operational. Thank you and good flights
