The reciever can basically be treated as a 3.5mm headphone just without a microphone. When receiving a call, you'll be able to hear the voice of the caller but the voice input would be taken from your smartphone's microphone

Kindly check the errors section :D

If you need amplification at the reciever end, then yes you might need a rechargeable battery for portability. If the power delivered is sufficient, you can do without the need of a battery

Great Job!! Thanks for the additional input, much appreciated 👍

That's such a great project dude. Cheers!!

Glad to hear that, have a great day =D

Depends upon the led and battery you are using...

I think your best bet would be to enclose your setup in a dark area or to use a higher power led. If you are making it for demonstration purposes, you can use some kinda material which is translucent and reflects light from one surface. Then you can form a tunnel like structure around your setup. You can also try placing solar panel/receiver closer to the light source. Maybe you can try switching to a brighter led such as a white one. I hope it helped. Happy making!!

Yes you can use that with the appropriate conditions applied. The main thing the solar panel is doing is receiving the signal and turning them into electrons. So i think it should work out.

The problem is that the headphone jack can't provide you enough power to power up the led to a high enough brightness. Its the same case with high end headphones if you can relate. You can power these on a $2 mp3 player but you need a high end Digital Analog converter (dac) to get the full potential / get enough volume out of them. One thing you can surely try is powering with the usb c port of your phone as well as transmitting audio through it as most modern smartphones don't come with one. Hope it helped.

Thanks. At first this seemed like a 'not so good' project but it's really nice to see people's interest. Do try building one yourself... Its easy. Best wishes

The main part which you need for this project to work is the amplifier of the speaker and if it has an inbuilt battery too, then better for you. I chose a speaker with an AUX input, inbuilt amplifier and an inbuilt battery. Having an inbuilt amplifier helps a lot. If you are confused, just go with a Bluetooth speaker which has AUX input connectivity. Switch that speaker to AUX input mode and everything should be in working order. Hope this helped and do feel free to ask more doubts about the project. Do share your's when it's complete under the I made it section. Thanks

Hi dudeIf you choose a higher resistor then you will have to change your power supply too. I made my circuit with the most commonly available supplies. If you want most security with your circuit, I suggest you using the circuit I provided above. Hope this helped you. Best wishes for the project. Thanks

Hi there,Actually I haven't experimented many circuits with this DIY project but I decided to go with a white led because of its higher intensity. Usually other coloured led's are dimmer and not as powerful. Hope this helps you.Happy DIY Day!!

I suggest you using a 3W white led. I have also given some causes if the circuit is not working so please do read them. A problem may be there with your jack as it occoured with me too. Loose connection may also be one problem. Do share your's when you complete it. Feel free to ask any further questions. Thanks

It reduces the risk of you circuit failure as it will prevent any extra current (if flows) and can also save you led from just getting fried up if you supply a higher voltage. Happy Building ;)

I don't think so that it needs to be a copper wire specifically but here is a tip, crack your device open and check whether any of the two open wires are in contact with each other. If this is happening then try moving them away from each other and if possible while soldering the components, you can use heat shrinks.I hope this solved your queries and feel free to ask any more questionsHAPPY MAKING ! =D

Thanks do share yours when you make one too

Ya ! That's true but the image produces a holographic kinda effect

NiceI think it will do a great job in your car

Oh this is really great

You have 2 choices here If you know soldering then you can use the spare jacks which you can get easilyIf you don't know soldering then you can directly use the jacks from earphones but you will have to find the connections in it which would be a bit difficult I suggest you to use spare jacks. ThanksHappy Building : )

Nice cute little toy. I will make one myself

I Respect your Views. Actually I was not sure that will this project work or not. But it works seamlessly well. The Joystick method will be a little complex and is difficult to design. The joystick console can be 3D printed but I can't 3D print it because I don't own a 3D printer. Well thanks for the Idea. I will try this out on Cardboard and Post another Instructable if it works.

Great I'm also a Beyblade Fan !!

The ldr's contact area will be smaller than that of the solar panel's so, it will cause a problem in receiving signalsHowever if you are using a laser ldr can work I think

ya i'll soon post an instructable in this regard
