This is exactly what this is - a DIY project.

It would be nearly the same cost to make a few by hand and sell to you as it would be to buy commercially.

Have you seen this?

Hi Z,

I'm also using 0023.

I made a clean install on netbook and copied your RF22 library (from your post above) into the clean libraries folder.
Copied the code (from above) and made a new pde called 'rf22_specan_simple' and veried it.
It compiled OK.

Ran up your RF22SpecScan.exe and it runs fine.

I'll try some more later on my main PC and Laptop as this is where I want to mostly use it.

I got my parts together now for a build of Zitrons latest board.

Works fine with the 'blink' test program.

When trying to compile the specan.pde - I get lots of errors due to missing files...
FastSerial.h
RF22.h
C++.h
Menu.h  -- and many more.

@ Zitron,
I guess you use other library files when making your specan & Tx/Rx firmwares.

Is there some single download I can get the required lib files or do I need to hunt them down individually?

EDIT
Tracked down a bunch of missing lib files and now the only remaining compile error is:

C:\Arduino\arduino-0023\libraries\RF22\RF22_Specan.cpp:379: error: prototype for 'boolean RF22::setFrequency(float)' does not match any in class 'RF22'
C:\Arduino\arduino-0023\libraries\RF22/RF22.h:813: error: candidate is: boolean RF22::setFrequency(float, float)


What do I need to change/add??

/EDIT


So close and yet so far !!

What differences are between RFM22-S1 and RFM22-S2? Only the crystal size?

Yes, as far as I am aware, plus €0.50 better price !!

Nice project.
I made something similar a long time ago but without Arduino.
Maybe I will re-visit it...

Possible the best flashgun for this is still the Vivitar 285 with variable power (flash speed/duration)

My PCB's are in the post as well smiley

I ordered my HopeRF modules here

Hi Zitron,

I'm still interested, I'll PM you over on FPVUK.

Regds,

Hello Zitron,

Great work and very interesting that you made your own design boards.

I see you are in the UK, have you seen the FPVUK forum post(s) regarding 459MHz use?
It would be good to see you over there.

http://www.fpvuk.org/forum/index.php?topic=2551.new;topicseen#new

What are your plans for the smaller PCB?

I'd be very interested in a couple of smaller (Futaba module compatible) boards - I'm willing to assist with costs.

Regds,

Nigel.
