glad to see someone else having such great sucsess with it. joystick is far easy

Just as an update, i recently removed the end point adjustment from my code, i have a sneaking felling it was causing drift in my copter.
will add you to the code thingy now stylesuxx

cardboard

If im not mistaken the reason for only connecting one esc to power the arduino is a safety issue. Having multiple power supplies connected together can lead to problems with voltage difference across the escs, one esc trying to power another one, possible ground loop or similar effect maybe?? I don'...

cardboard

nor can i arm my copter, the status light on my promini blinks rapidly and that is it. I can trim acc mode still though if that is any consolation.
she still arms in 1.8 though

cardboard

ESC dont push out amps, they provide as needed. The motor draws amps and you must make sure that you match you motor with an appropriate esc so that the amount of amps the motor wants to draw is equal to or less then the total of which the esc is able to provide. As in your situation you have a tota...

nicely done, be intereested in seeing how you redone it. I reworked someone elses code when i did it as well. Over the last few days I have integrated a wmp into my fpv goggles and use the arduino on board my joystick to work headtracking into one of the spare channels. btw how do you add people to ...

cardboard

this dev looks really good. got out for some aggressive flying in no wind this afternoon. My pids are a little off so it was twitching but the drift issue seems to be all but solved. it only drifted off twice and they were only small drifts that were very manageable. i think after i replace the bear...

cardboard

just fired up the old tri in the lounge with the new dev and it works really well. both acro and stable mode look promising. its really windy outside so i cant test fully but the next time its fine ill try some aggressive and fast flying to see if it holds up.

cardboard

i love the idea of using the sensors already on board for osd, there is no point having two of everything. What about using somthing like the MAX7456 http://www.sparkfun.com/products/9168 and using the arduino to power it? once gps is integrated you'd have everything. just a matter of the available ...

cardboard

the trim is relitve to gravity, and thus level ground. I had the idea of putting the level out of a cheap spirit level on each of the booms. so i knw my copter is sitting dead level when i power it on and know my trims will be pretty dam close to perfect every time.

cardboard

i have those same gliches in my gui, not as frequently though.ive had a few nasty crashes before it started happening. might need to buy a new one as well

cardboard

stable or level mode uses an accelerometer (ACC) in conjunction with the gyro to keep the multicopter level when there is no control input. contorls are best disscribed as angles, so the angle of the stick is relative to the angle of the copter. acro mode only needs a gyro and is more like flying an...

cardboard

Yea 1.3 is far nicer to look at as far as layed out-commented-completed code goes.
No wiki as of yet, there is the wiki built in to Google code but i don't think its that amazing purely because I don't see it used.

I hope the Corona module doesn't take forever to get to you.

cardboard

have u calibrated your acc and are all your sensors oriented in the correct direction?? You may also have to play around with your pid settings, your booms look rather long so you may need to tweak some values to match. On a side not I personal find that ground effect and hitting the ground causes s...

cardboard

@cardboard I went through the Code yesterday, just Version 1.0 for now and I have a couple of questions: * The trim settings are only saved not read out anywhere * god and jesus are only there to check if the trim settings changed * what is this dualrate stuff? Do we need that? * there seem to be t...

cardboard

Im using a lillypad which is basically the exact same as a pro mini so it should be fine, The only reason I mention a specific joystick is that I've come across some really old joysticks that use a light sensor array instead of pots and some really new joysticks use other optical rotation sensors in...

cardboard

it is a saitech joystick with a corona 2.4 DIY tx/rx set thing. any with ppm will do the job tho

cardboard

Ok its all up and running now. http://code.google.com/p/tx-joystick/updates/list 1.3 works pretty dam well but if you want to write your own code based on mine id suggest looking at 1.0 and up as they are very minimal and would be easier to build on from scratch. Also check out the work I based mine...

And go Pendulum!!
Team Blacksheep (my personal fav fpv guys) have this video with Pendulum soundtrack.

i tidied up the code a bit today, commented it some more and what not.
Was going to make a google code project to host all the work but it seems its down for maintenance.
Ill post a link here when its all up

cardboard

I'm not sure what you mean by dots but it doesn't matter if the motor faces up or down the prop always faces forwards. On the prop there should be writing saying width and pitch, this writing should be facing the direction you want to go, in the case up.

cardboard

the smaller props have less mess, so don't have as stronger force at keeping the copter level. all my settings a default. It would be interesting to test the amount of thrust you produce with each different prop set. i normally just mount my props upside down, reverse my motor direction and power it...

cardboard

your setup seems very similar to mine. motors are the same weight and with 100kv, i use similar size battery and 10amp esc. AUW of mine is around 600g, that takeoff weight, battery fpv etc etc. It sounds like you have flat batteries, or your motors aren't giving the correct thrust. I have 1400Kv mot...

cardboard

BlueAngel I had that exact same error!!! I was in fast fwd flight, my tri twitched a bit so i leveled out then a few seconds later i lost all control and it slowly rolled into the ground. here is the footage from that day. No damage to any electronics just a busted frame. From 8sec I lost control, I...

The 2 plates are plywood cut with a hole saw, the booms are 12mm square pine. Its rather sturdy but is on the heavy side, almost 700grams in i remember correctly. This is the newest design- fully loaded with fpv and a 2200mah batt its only weighs only 500g and the performance gain is huge. With a 13...

cardboard

If I am not mistaken this is to do with the I term in the pid loop. When the copter is in free flight, (not supported by your hand/ a desk) this value is self correcting resulting in balanced flight. I think if you were to power everything up and get it to hover whilst plugged into usb you would not...

cardboard

I have recently been battling motors cutting out randomly. Its very very intermittent (might happen once every 5-6 batteries) so I keep hunting down hardware issues. Seeing someone else has a similar issue is interesting. I'm considering going back to 1.7. as much as i love 1.8, 1.7 seems to be the ...

cardboard

Just going to list all things that go through my mind when you say its not pushing as much as it should be. Has that particular ESC been calibrated? Is the prop-- loss, damaged(cracked or chipped), is it balanced? Does the motor spin freely? If you swap motors does it happen with the motor you moved...

cardboard

Your photo isn't the best in the world so I'm not sure if pin 1 as you have labeled it is a pin, or just solider pad. But if you keep the board in that orientation and start from the top and working your way down from the first pin they should be numbered as following. 1 + 2 SCL 3 -- 4 -- 5 SDA 6 GN...

i use 1400kv motos with 8x4 props, turnigy plush 10amps, 3cell. they work a treat so i think you can rule out motors

cardboard

with new sensors--was adc accel ADXL335 and ITG3200 gyro--now original nunchuck and WMP and 1.8P2 everything is amazing again, I have a felling the old sensor combo was not playing nice.

cardboard

@spagoziak I have just been out flying and have managed to get rid of the issue concerning not coming back to true level every time. I was using an adc accel (ADXL335) and the nunchuck clone with the ITG3200 gyo (modded with direct connection such as the following, http://imageshack.us/photo/my-imag...

cardboard

in relation to that youtube video. I have that issue with my big tri. The issue is currently tabled atm but when i have some free time i was going to try and sort it out. In my case it is as if one motor stalls basically, then flips and crash. Be interesting if you find a solution.

cardboard

it didn't seem that the MWC made it to true flat level; instead it chose slightly different angles every time I recovered from flying in a particular direction (so auto level trim wasn't a factor here since its tendency to lean wasn't toward a consistent direction). spag agreed, i also experience t...

I havnt had a chance to go out to the park ye, stupid weather, but cursing round the lunge with level I set to 0 does seem to solve the particular issue i was having

I've checked two things, port everything to 1.8p1, but this not solve the problem, and then I set I=0 for Level and now everything is OK. No problem with drift. But what for is I for level ? In my situation drifts come from cheap transmitter (HK-6A) middle position is around 1500 but never equals 1...

not worrying about my drift issue I do not like the over shot level mode gives in normal working conditions. The worst example is in fast flight, when the sticks are released my tri does not go to level but over shots. so if im flying fpv and get a decent forward angle/speed then when i level out th...

cardboard

By trim I just mean the normal TX trim on the axes that is being effected. The ACC trim, how much effect does each click have? I tired doing 4-5 trims in the manner you suggested with little success before I posted here. Does it need allot more, say 10-20 to make a reasonable impact?? Iv'e looked b...

I'm glad I'm not the only having this problem.
Check out this thread maybe there's a bug in the code or we have a slimier hardware setup that has an issue.

i just uploaded 1.81 to my board and although my acc still reads 196, hovering in the lounge seems ok. I did remove the 100g of fpv gear and i think the reduction in weight made it more twitchy then normal. I Tweaked the level pids and managed to make the correction time lower so im happy with that,...

cardboard

So I got a chance to test out all the advice i have been getting and wooow some very interesting results. Leaving tri sitting for a few minutes on the desk, no change in any sensor but put my thumb on the acc and it jumps from 196 to 230, never knew that could happen. Gyro has no thermal effect. ACC...

Thanx Patrik I'll try these out when I get home and let you know how i get on.

have you tuned it in acro only mode? I cant fly in acro mode..... Iv'e only every flown fixed wing aircraft so level mode was an easy step up.

Temperature drift?? Interesting idea. This happened throughout my 30min of flying today so by the end of the flight I would have imagined that all the boards/ sensors would have equalized to air temp. I was flying right after sundown, in a valley so sun just went behind the hills. So no direct sunli...

edit, re read your post *faceplam*. My mate also has the hobbyking radio and 'switch B' is default setup to be throttle cut. Its meant to 0 the throttle stick. You need the programming cable and software to change the switch operation and radio functions. Check out the discussion tab on the product ...

This problem sounds familiar, well problem 2 does anyway. Do you have a common ground between all your components, its sounds to me as if your Rx and arduino don't have a common ground. I learnt this through trial and error when I first built my multicopter as well. I'm not sure how much you already...
