Of course the specs for this LMA doesn't list the operating voltage, which some have already pointed out needs to be something less than 5.5V.
I wanted to use a HK LiFe receiver battery pack, but the nominal voltage is 6.6V.
Solution: I took an LED from an old phone and put it in series with the red wire to the Rx. It brought the voltage to the buzzer down by about 2V, and now it works great.
Yes, it will work with any rx, you just need to plug it into any channel(flaps or gear retraction switches are best choice) and when you activate, it will beep when you activate it. Please award credits if I helped.
very easy to do if you have the turnigy 9x just plug it into your gear channel on receiver channel 5 go into your transmitter go into setting's scroll down to aux-ch push menu button once see ch5 left click 2 time's on your leftside gear will appear push menu button once then exit button 2 time's your ready to go, on top right on transmitter see gear switch when you turn it towards you turn's it on turn it back shuts it off,you can use it anytime you want.
When I try to play the videos for the Discovery buzzer, I just get a wait icon with a circling character. Does anyone know what might be my problem? I'm running Windows 7 on a machine that has no problems with MP4 or Flash videos.
To Juan Martin and Lucio.
Please try to read what Virginia is asking.
She is trying to see the videos in this page and she cant, that is why i suggested her to install some codecs, thank you for your great help
I gotta say, reading these comments is a kick in the butt! Virginia is my state of residence, not my first name and is correct about my question. It is in regards to my problems viewing videos on this product, not a question about the product.
I got a DB measure of between 54 and 70 at one meter. I put the buzzer on the floor facing up and at one meter I got a rating of 65DB. I then turned the top of the buzzer to face the microphone and I got 70DB. When the buzzer was inside the canopy of my Bixer I got 54DB at one meter.
I mounted it on a 450 Helicopter.
I tried to switch it on during flight and at about 50 meters I can heard it clearly regardless of the noise of the heli.
I think that when you crashed the heli/plane and it will not emit noise you can hear the buzzer even at 100m
I think you can use "Y" type servo wires. And you only need 1 channel in RX:) I never try this but maybe it will work :) You can find a lot "Y" type servo wires in Hardware & accessories>>> Wires & plugs >>> servo wire & servo plugs.
Yes you can just be careful as they draw a lot of power and have rf noise feed back. Just make sure you have a good bec around 5a and you shouldn't have any problems. Mine, when turned on makes all my controls twitch a little bit every time it beeps. I'm using corona RX.
a set decible level will not produce a higer level just because you add a second source to the mix
think of having a sterio volume set at 2 running on a left only speaker then you add the right speaker it wont produce a louder volume just a sterio sound
i think the only way you could produce a louder volume is to replace the buzzer with one from a panic keychain if you find one available thats louder than your discovery buzzer keep in mind the more louder sound it produces or adding anoth
It's not that bad but now you have similar product with more function. This one does one thing, buzz when you activate switch on channel connected, no low voltage alarm, no out of signal alarm ... But works. I use it and it's simple switch on and buzzing.
vous ditent simplement mais il est independant..pour retrouver un model dans les ble ou le mais sais ideal...pour la basse tenssion mieux vaut un syst plus sofistiquer conne le syst quantum pour 59$ vous avez une telemetrie correct tension batt et chaque cellule et avec le tuning les Amper et la conso en W..
Again, what do you mean "now you have similar product with more function. "?
Those other two are activated a different way, but can't be activated manually, like this one. So they have different functions, but not more functions.
similar not same, buzzer - one function - beep on switch, PRODUCT ID: 9171000001 no signal and low voltage, PRODUCT ID: OR022-01702 leaves Chanel available, but not one beeps on switch. I agree, different function. I have this one and PRODUCT ID: 9171000001. So beeps on switch and on signal loss and on low voltage. Thera are 8 ch in T9x so it is shame not to use them.
They could make buzzer low voltage signal loss in one. Or you can combine like me.
I have tried to use it in my trex500 with 7ch futaba FASST. I do not use GYRO /channel 5/ for controling GYRO - I use spare channel no 7 instead. So the only chance where to plug this beeper in is GYRO channel 5. Many hours spent but it just beeping randomly - f.e. mainly if I move with heli left and right. Impossible to switch anything - it beeps when shaking with heli but cannot switch on/of. PLS HELP !!!!! THNKS JIRI
Hi. I have Futaba 7C as well. As far as I know, the channel for gyro is channel 6, which is controlled by rotary knob on the upper right part of the tx. From your discription I made 3 questions: 1) Why you can not use gyro on channel which is ment for gyro and is hardwired to a special knob? 2) Most probably you have some mixing working, because this beeper has to activated by a switch from tx. 3) What about channel 6? In your description there is not a word about it. Regards
Hello, You can use every receiver and every channel you want. Stick or Switch is possible to activate it. You can use it for microreceiver too, but if you want this you must have the right connector. Put the Buzzer in the middle of your Plane, i mean its the best place for hear it. Dont use soft Foam there. Glue it on the wood, fiberglass or Epp. Much Fun...
The microcontroller on the board produces a pulsed signal to the buzzer to make the tones. This would be unsuitable for LEDs unless you wanted the to flash. (To drive LEDs, you may also need a driver transistor to boost the current output.) You are better off buying the Turnigy REceiver switch (LUM-ONF) which is built for the task.
FYI - I posted a waveforn of the output to the buzzer in the files section. The stock buzzer draws 20mA but I was also able to operate it with a 100mA load. The micro is an Atmnel tiny13a. The beep pattern is _ . . . . . _ (repeat). I did experience some random triggers when only battery and ground were connected. The buzzer comes on at > 1600uS. with 1520 uS as center, there should be no need to change channel end points to make this work.
The measured volume is 86dB at 6".
It expects a positive going input pulse and will not operate with a negative going pulse.
If you remove the buzzer to use this as a receiver controlled switch, the load will be turned on/off accorfing to the pattern above.
>> Than it will beep. If not, maybe its dead. <<
It don't must be: If it not "BEEP",pls check, if you can increase your way and try again (e.g. change the Servolimiter from 100 to 130 ) on a $pektrum TX/RX 100 are enough.
loud enough to hear in the bushes if you keep quiet. Advised to put beeper either out of the plane or with a whole in the airframe. I tried activating it in the air and i could hear it from 200 or so metres away...
pretty piercing, good for what its for.. haven't needed it yet knock on wood. Estes used to sell one of these self contained for finding rockets. The kit also came with like a directional boom mike to amplify its effectiveness, if you are concerned about effectiveness, pick one of those microphones up.
I got my plane stuck high up and found it audible from up to about 30metres but identifying direction of the sound at that distance was difficult. You need to have an approximate zone but if you are in long reeds or bushes it is great.
output voltage, same as the input. Depending on your receiver battery pack voltage. If you remove the buzzer, can can use a 500 ohm resistor in serie with a standard LED, or use a standard transitor like 2N3906 or TIP31 to drive more LED
That not good news - I run most of my Slope gliders on 6V via BEC .. some of them I can switch to 5V .. will this buzzer work correctly on 5V.. I also have a few I run on single cell lipo 3.7V .. any chance it will work at this voltage?
I guess the buzzer is directly connected to RX voltage, so you will get around 5V, so it should work with the lighting system (rated 4-6V)
Anyway, why do you need this buzzer without the buzzer? just for the connector?
> Does this buzzer work with 2.4Ghz Spectrum system? : Yes he does* I'm using this item on the AR9000 (9CH) $pektrum Receiver without any problems. Someone wrote, you can hear it ~200Meter:I don't think so, but if e.g. your Heli/plane in a field, you will found him very fast.
You cann't make Hobby King Discovery Buzzer work? Very simply connect to any channel and set the value of the channel remote to set it ON, set the value for the channel -1 to -100 to set it OFF set the value for the channel button on the 0 to 100
COOL NEW USE: This is simply a PCB that responds to an Rx signal and switches on a voltage to a piezo horn... but it's also each of those parts separately, and for LESS money and size than a remote switch sold elsewhere on here. So, I tore off the horn and replaced it with a string of 4-6V LEDs, and VOILA I have remote control of all my in-flight lighting in a TINY package. Seems to be running at least 250ma of load safely, but could be capable of more (I haven't tested).
You could test the buzzer with amp meter to determine what the draw is. You could also add a mosfet transistor to handle higher loads. HK light strings (60 leds) take 400mah each and might be a little too much for this application without the mosfet.
Thanks lightwave... I wasn't even thinking that some people would be nutty enough to use an entire 60 LED string with this method. Aren't those strings 12V anyway? I typically use a dozen 4V LEDs (up to 18-20 maybe?) with mine with no problem, but a longer string could brown out the BEC's output and do bad things for your servo control. Definitely right that you don't use this method for HIGH drain lighting!
Winged Shadow has a similar device but it also tells you the current voltage, min voltage, counts glitches, and low voltage alarm. I know this is cheap but I think the additional functionality is worth the extra $$.
What does you want? 2,79$here - or the other one with function (does you really trust the add one?) for 24,95$?
I trust, for myself, more the Logger, which I can connect on my RX ($pektrum). Also without Logger you've with a $pektrum RX an optical control: If the LED in the RX and/or Satellite is blinking, the signal was lost for a short time. My RX has an own LiPo - and he is already ~70 full after all Fly-LiPo's are empty or I'm using a U-BEC. Here the Voltage from the RX is the latest one,
This responds to an Rx channel going full-swing. They work on ANY brand radio, but $pektrum radios are often held by users with less understanding of what's actually going on. Adjust your endpoints, and it should work all the time with any radio.
> but $pektrum radios are often held by users with less understanding of what's actually going on. <
It isn't true: the item works without any problem on a AR9000 and 100 in the TX. I don't must increase the way to e.g.130
The piezo is round... very very very easy to drill a little round hole for it to stick into... :-) You could even drill that hole into the intake-side of an EDF's windtunnel, and have it cosmetically hidden with little reduction of sound.
You can change the buzzer by himself again another (louder)one - or - you split the item: the part for switching let in the plane and only the buzzer via long cable fix somewhere outside ... In both case you must soldering.
You can install it on an spare channel and program it on a failsafe mode so it will work even if you loose the signal from your transmiter or you can turn your Tx off to activate it . To avoid a battery disconnection some time helps juts using a tie wrap putting together the RX with battery cable connected to it.
I would never have found my motorglider that went down in thick forest without this Peeper. It's not really loud so make a small hole in the Fuse and poke it in from the back so the sound level can be doubled.
