thUndeadMod v3.4 - openLRS S**T just got real :)

[Coyote]

Cool Dennis, tried and tested, much better, one of the scales ( cant remember which ) didnt autoscale though as the values increased, not sure if you knew or not

[MarkLincs]

Been looking at openlrs but until the 459mhz is sorted and UK legal I'll wait

shame transmitting on 459mhz has issues

Glad you like the improvements  ;D
I'm probably not gonna update much unless someone have ideas for improvements.

Can you check the scale that didn't auto-scale? I haven't noticed it?

Pretty sure someone awhile back said they would be interested to see whats inside a EZUHF, I borrowed a friends one and took a few pictures. The RF modulator(?) is an Si4432 which is the same as the RFM22B I believe.

Heres the link to the pictures http://www.flickr.com/photos/44091057@N04/sets/72157629509703908/

lmao I'm in denial lol. that explains why it can do 459 easy. but it probably has a completely different back-end (rf filters, power amp etc ) I think. otherwise it would have been as crappy as openlrs on 459

I have 2 comments to make, 1st is Dammm your camera has a good macro mode!  and 2nd comment is that I am pleasantly surprised about the chip being used.  Looks like OpenLRS is the ugly cousin of EzUHF lol  Ok so filtering is going to be a little different no doubt, but even then I am not so sure as the EzUHF covers the 433 band aswell.  perhaps there is an issue with the design of the OpenLRS or and its a big or something could still be done with code. It's a glimmer of hope thats definate

On a side note, some others are using 459MHz... (checkout some of the distances involved ;) )

Sorry to be a kill joy but there is no reference at all on the whole of that page to using 459MHz at all.  2/3of the way down the page there is a shot of a UHF tranmitter that is using 434MHz!  I know at the end he is using a RFM22B module but there is no code supplied and no reference to what band he is using

[thundead]

ummmm guys, 300 baud vs the 9600 my fw is using. That's why they can achieve those distances. takes them ages to receive telemetry but they are obviously in no hurry lol. Also telemetry is legal to send on the 433 band in the uk (someone correct me if im wrong).

Also sorry havent been very active with new releases. Uni is killing me lol. a few more weeks and I can restart dev after 15 may (final exam). I'll start making my own ezuhf if I really get pissed off lol.

The pictures were taken through a magnifying glass with no macro mode on my phone.

This definitely shows that the basic fundamentals of the system are sound based on the range that EZUHF has got to.  ;D

Is it just me or does it seem pretty amazing how this isn't banned yet we aren't allowed to fly beyond visual sight with our plane even though we actually have control over it.

Quirk of the law I'm afraid.  But there are apparently controls in place for a safe launch, etc.

I once read a guys balloon flight where they had to hire a RIB to go 30 miles into the North Sea from Holland to recover their payload.

Back on topic now :D

Ok a little update :

After the problems I had I started fresh, I fitted a brand new Rx as a TX in my Turnigy 9x, turns out its IMO much easier and better than the flytron TX, everything fitted inside the module case with room to spare. I tested that and RSSI held fine unless I moved the stick fast then I could get it to glitch to 0. This aside it seemed better than the TX installed so I went for a flight. Then I fitted brand new Rx to Skywalker to rule out that as well

1 flight with the Skywalker was fine, very windy so was not fun but landed to have another flight, swapped lipos, then I took off and within 200m OpenLRS lost RC link and Skywalker came down that hard in the wind it was in 7 pieces :(



On review of the video RSSI had started bouncing to 0 again just before I launched ( lunched LOS so had no idea )

Obviously I was not impressed, I can not conclude that its OpenLRS fault entirely because it might be my Turnigy 9x, but I have ordered my Chainlink Rx`s and I`m going to test the RSSI of the Chainlink and see if I can replicate the OpenLRS RSSI bouncing, if not, there`s something wrong

[thundead]

shit thats bad. right...

!!! IMPORTANT !!!
everyone using my fw please revert back to 3.1 ( fw that had rssi on pin 7 ) for the time being. I'm deeply in exams so can't work on the olrs atm until after the 19th of May.

Thanks.

[Dennis Frie]

Sorry to see that  :(

thundead - I'll deliver my bachelor project the 24. may, but should have quite a bit of time after that. I have considered to write a new frequency-hopping algorithm and re-write a bit of the original code by Melih.

Perhaps we can figure something out. I have a bit of equipment that can be used for testing and logging.
