Hello all

I´m Henrik, first post here and sort of beginner at this ( use to do some embedded stuff some 15 years ago and picked it up again recently )

I just did a shopping list for this project, Version 2.0 if I got it correct
here it is: http://my.aliexpress.com/wishlist/shared.htm?groupId=3106453469
As an example it should be about 20 euros if you buy to be able to make 5 whole sets.

I added 3 additional and optional things to the original BOM:
battery holder + battery connector to make it easier to change them ( I think )
straight pins

I did this for people searching for the components needed that does not have any or very few before starting the project.

Only thing extra needed I think would be some additional cable and a arduino UNO or some other way to program the single chips. But I assume you already have a UNO if you read this
And a soldering iron and that stuff.

(if even one person found this useful I guess it fulfilled its purpose)

I just wish Mozilla could introduce some more settings in their web interface. Just to edit nodes and bring back nodes that you deleted etc, in an easy way. The easy interface is pretty and all but it would be useful with some more settings options etc

@neverdie Alright , that took me a couple of days of fighting with Arduino/Linux/windows/drivers/bootloaders etc etc etc but I got it all running with my updated gateway+repeater-node + mailbox-node. did not try the update function yet but surely it should work. just need one or two more repeater-nodes since I have way to thick cement walls here for this signal.

@neverdie
Just tried it by mounting an "empty" 328P in the node just with the
fuses set to:
0xE2
0xDA
0xFE

and with the MYSBootloader .

Amazing ! . worked at the first try! (this time around =D )

( tried and failed a couple of times earlier, but I know I burned 0xFD instead of 0xFE so set the BOD to the wrong value, and that does not work )

@kurtsejr Aaa ok.. yes that is true , I installed all that extra from start so that issue did not appear . good you got it solved !

@neverdie OK, that person who knows something is now ME ! =D ... RTFM ... as always , it worked strangely enough to update ONCE with some slightly wrong Fuses set... reloaded the bootloader with soem correct fuses agian .. ( hopefully alst time .. and VOILA! now it works to update the node multiple times .. yeaa.

OK MY solution was actually the fuses that I said earlier . but confused myself by changing them back and forth a couple of times and downgraded Arduino to the previous version etc.

So the fuses for my barebone 328P are:

proMYSBL8.bootloader.low_fuses=0xE2
proMYSBL8.bootloader.high_fuses=0xDA
proMYSBL8.bootloader.extended_fuses=0xFE

the biggest issue I had was probably with ARduino IDE .. that one I enver manged to set the fuses ( I read somewhere it should.. but maybe I´m wrong) . Anyway it works when I set the fuses and upload it with AVRDUDESS.

(note: hello me 1 year into the future, just do what I say ! )

I just add another note to myself ( And anyone else that lost their hair wondering why the bootloader was lost....)

DO NOT UPLOAD SKETCH ONLY WITH USBASP ... it deletes the bootloader .
yes I know it is mentioned on the foru m.. just found it .. but I mention it again...
