At first when I saw the name I thought it was an upgrade to the bluetooth as in making it have a stronger signal, but now i guess it just allows assessories that are made to hook up via headphone jack into bluetooth.

yeah you're right the upgrade's is all about to allow any 3.5mm jack in radius of 10 meters and increase battery duration...
It's hard to increase the signal strength...
But you gave me a new IDEA. I'll work on that..

smolnár1 made it! (author)2015-04-07

I made it but it is braying.

Tech Works (author)smolnár12015-04-07

You made it... well tried.. but you just done some serious mistake in this..

remove your battery of you bluetooth headphone and connect you charger power after converting it to 3.7v

you connect the power source with the audio jack

Is the sound good ?. Secondly, its a single channel audio it will not have effect as of stereo and would sound blant. Lastly can we hook up a camera speaker to it?

Tech Works (author)samalert2015-03-18

Yes my dear friend your queries are genuine..

1. Sound is good according to your earphone/ Headphone

2.yes it have no effect as stereo.

3. I think so

samalert (author)Tech Works2015-03-19

I have a spare cell phone speaker but sadly it does not produce sound i am really not sure why but it works good with 3.5mm jack

Tech Works (author)samalert2015-03-20

you just confused me.... your speaker in working or not?????

samalert (author)Tech Works2015-03-23

See my idea is use a cellphone small speaker which is smaller than coin inside a helmet. So i did hack the bluetooth receiver and used the small speaker but it does not produce sound.

I did not used any external battery may be there where i am going wrong. The speaker have RED & BLACK wires and i directly connect with the bluetooth wires.

Tech Works (author)samalert2015-03-24

great you are at right place. now connect red wire to +ve terminal of bluetooth speaker and black to negative terminal... if you are facing some problem then send some pics... i tried your idea in past I connect headphone speaker's to my bike helmet and it's works... for more details of connecting wire to terminals go to my this page

you don't need external batteries but if you used that battery that will drain very fast...

good luck friend......
