Any electronic enthusiasts out there who could design a Rider - Pillion Communication System? Simple lang sana yun di ba? And its a good idea too right? There are available systems now like the Chatterbox pero sobrang mahal.

How about 2 alaska cans tied with strings. Balik na ako sa kabila:clap:

kasya ba alaska can sa loob ng helmet? bumalik ka na dun!!!

You could buy a simple 9-volt intercom sa raon, then buy a couple of headsets (with mic), mini-jacks, wires...DIY na lang...I think this is simple enough.

Hmmm...mahalukay nga yung intercom ko dito, this would make an interesting project to do. :)

Check this link below, sana makatulong.

Saan sa Raon?

naisip ko nga rin yung intercom, pwedeng kabitan ng headset with mic na lang tapos ilagay sa belt bag yung intercom. alam ko kasi kailangan mo pumindot bago ka makapagsalita...pwede siguro yung backride mo na lang pipindot para sayo. bigyan nyo naman kami ng diagram kung pano i-DIY ito.

malaki kamurahan nito kaysa chatterbox.

ayoko nung pinipindot pa dude, pwede naman yatang a low watt amplifier small enough to fit your pocket, na may simple 2 input mixer so you can stick in 2 mics. this way, pwede kayong sabay mag salita. yung pwedeng gamitin yung headset with mic boom ng celfon para cool, di ba?

mas cool nga ito bro! meron bang makakapag bigay ng diagram kung pano ito magagawa? kahit ipagawa ko na sa electronic shop kung medyo mahirap i-DIY. tulong tulong saklolo!:D

up ko lang!

Saan sa Raon?

Kahit saang electronic shop sa raon sir merung available na portable intercom.

intercom kasi di pwede sabay magsalita. a small amp with a small mixer for multi inputs would be cool.

meron po bang may alam nito?

hjc chatter box..

http://www.hjc-chatterbox.com/

mga kaibigan, meron yata mabibili dito sa deeco, metropolis alabang na 2-way intercom. pwede yata na gamitin sa m kapag may passenger kayo, kaso may PTT pa para magka palitan ng dialog. 1 speaker for mic and speaker. pwede din siguro ang pre-amp na gamitin for 2-way com ng rider at passenger. try nyo na magkabit ng speaker(earphone) at mike in parallel para pwede magsabay na magusap ang 2. paki-comment naman po sa mga electronic gurus dyan.

if you have read above, chatterbox has been already noted. this is really very ideal, pero ang mahal!

just curious if pinoy ingenuity can work something out with a cheaper alternative.

any updates?

motorola talkabouts + throat mic. ;)

motorola talkabouts + throat mic. ;)

how much are those?

LBB, I remember working on this when I was in High school... An elective project. It's a small amplifier from Raon with input for 2 microphones and 2 headphones operated by 1 9volts battery. No need to press anything to talk but you cannot speak when the other's talking (vice versa). I dig up my old stuffs later and see if I still have the diagram. :)

Lbb,

Will you need that in a motel?

how much are those?
motorola talkabout costs 2000+ a pair. throat mics costs 3000+ each. mahal throat mics eh. this looks like the one that SWAT uses.

bro eto 2.8k daw. try calling 09175219327.

San meron nabiilhan ng throat mic?

jan sir sa pinost ko na number, airsoft shop yan.

meron din throat mics for other radios. check out http://photos.yahoo.com/ivan609.


di po akin yan ah, shineshare ko lang...

i bought an intercom from jetc of motrcycleasia forums. check the link above.

pede kaya bluetooth ng cellphone or handsfree, then mag subscribe rider and pilion sa sun unlited calls, before umandar mc natin mag-connect na? hehe. simcard na lang ang bibilhin im sure lahat tayo may cellphone na? pede ba yun hehe.

i use autocom

it can accomodate mp3 players, cellphone, gprs, radar, rider/pillion

no need for push buttons

Okay to ah.. sim card nalang ang kailangan mong bilhin. Kasi most modern cellphones already have the headset with mic sa bundle. Hmm.. maybe i'll just use this option. Pwede na kaayo mag sabay mag usap and no need to press any buttons.

Tanong ko lang, pwede ba 3-way conferencing ang sun cellular? Kung pwede, eh, okay na okay talaga toh!

Ang ganda sana kung may available na ganito dito sa atin. Sarap sana makapag-usap lalo na pag long rides.

Ito yung nakita ko sa web, pwede rider to pillion, pwede rin rider to rider. May 150 meter operating range. Brand is Interphone.

Bump ko lang ang thread, baka may ibang nakagawa na ng mga DIY.

sir gary mukang napakalalim ng pinagbaunan mo ah...hindi mo pa ba nahuhukay?:D ganda nitong project mo eh. sana may diagram na.;)

magkano nman ang bili mo nyan?

mga sir sana eto makatulong sana hindi mahirap hanpin mga parts di ko pa natatnung yan kung available satin mga parts. konting modification nalang sa speaker at mic para maconnect mo na sa isang headset

--------------------------------------------------------------------------------

Comments:
This design allows to operate two intercom stations leaving the operator free of using his/her hands in some other occupation, thus avoiding the usual "push-to-talk" operation mode.
No complex changeover switching is required: the two units are connected together by means of a thin screened cable.
As both microphones and loudspeakers are always in operation, a special circuit is used to avoid that the loudspeaker output can be picked-up by the microphone enclosed in the same box, causing a very undesirable and loud "howl", i.e. the well known "Larsen effect".
A "Private" switch allows microphone muting, if required.

Circuit operation:
The circuit uses the TDA7052 audio power amplifier IC, capable of delivering about 1 Watt of output power at a supply voltage comprised in the 6 - 12V range.
The unusual feature of this design is the microphone amplifier Q1: its 180° phase-shifted audio output taken at the Collector and its in-phase output taken at the Emitter are mixed by the C3, C4, R7 and R8 network and R7 is trimmed until the two incoming signals almost cancel out. In this way, the loudspeaker will reproduce a very faint copy of the signals picked-up by the microphone.
At the same time, as both Collectors of the two intercom units are tied together, the 180° phase-shifted signal will pass to the audio amplifier of the second unit without attenuation, so it will be loudly reproduced by its loudspeaker.
The same operation will occur when speaking into the microphone of the second unit: if R7 will be correctly set, almost no output will be heard from its loudspeaker but a loud and clear reproduction will be heard at the first unit output.

Notes:
The circuit is shown already doubled in the diagram. The two units can be built into two separate boxes and connected by a thin screened cable having the length desired.
The cable screen is the negative ground path and the central wire is the signal path.
The power supply can be a common wall-plug transformer-rectifier having a voltage output in the 6 - 12V dc range @ about 200mA.
Enclosing the power supply in the box of one unit, the other unit can be easily fed by using a two-wire screened cable, its second wire becoming the positive dc path.
To avoid a two-wire screened cable, each unit may have its own separate power supply.
Please note that R5 is the only part of the circuit that must not be doubled.
Closing SW1 prevents signal transmission only, not reception.
To setup the circuit, rotate the volume control (P1) of the first unit near its maximum and speak into the microphone. Adjust Trimmer R7 until your voice becomes almost inaudible when reproduced by the loudspeaker of the same unit.
Do the same as above with the second unit.

I use before an ICOM cant remember the model but check sa raon

sa Andernes Look for my Friend Jerry maybe he could help You!

Just stated your a friend of mine joms

actually motorola radios +throat mics are cheap. Most airsoft shop sells one motorola radio+ one throat mic for less than 3k lng. mga 2,300 ata if i'm not mistaken...

sir wala ka po bang PCB layout? TIA

sir wala ka po bang PCB layout? TIA

wala sir eh yan lang nakita ko sa net, bread board mo nalang muna tas ipackabge mo na maganda konti lang naman parts so pwde bord mo nalang muna pag samahin mo na yung dalawang circuit tas nakalagay sa ubox para dun mo nadi sa battery ikuha ng supply tas yung headset nalang nalang na dalawa ang nakalabas, sige sir pag may tym gawan natin ng pcb layout yan kahit drawing sa kamay lang di ko na kasi gamay yung protel na panggawa ng pcb layout
