Pretty cool idea can we make it better?

[mhemling33]

So surfing through amazon i stumbled upon this....

Amazon.com: Cyanics NoonTang Mobile Laser Pointer, Presenter Remote for iPhone 5, 4S, 4, iPad 4, 3, 2, Samsung Galaxy S3, iPod Touch 5G: Electronics

So what can we get to run off of an auxiliary jack :eg:

If it is 1.3V can we us a boost driver to get us around 3V.......

 

[Livinloud]

yeah we can make it better.......1w+ 445!!!! burn that white board down!!!

It will all depend on how much current will go through the jack. I highly doubt that it will be more than 10mA.

Also interesting to note is I imagine this works by supplying the aux jack with constant sound output. If you do not use the app with it, you would have half of a laser based speaker system. +1 if I can for the find! I may just get this.

The amplifier on the ipod touch v5 can source up to 57 mA peak into the 23 ohm earpods if the the signal goes as high as 1.3V peak.

How about using it as a laser range finder? Lame?

 

[Things]

Build a device in exactly the same form factor but containing a small photocell into the iPhone's mic input, sound over laser.

App that says "Pew pew pew" when the laser is active.

Interesting find but pricey.

Wow, this is actually a pretty smart idea!

Imagine the size of the attachment though if let's say the person wanted 532nm or 594

+1 for the find.

Seems rather gimmicky to me.
I think the best thing to do would be like what wannaburn said make some sort of laser communicator with a photocell and a sound signal into the laser.
Would still be gimmicky tho, because really, it's more convenient to shout than to align the things (and keep it still can you imagine that without a tripod or a rock solid table).

Still waiting for mobile dock that projects a keyboard projection onto desk in front, and an output screen on the wall behind :na:

 

[CheeseHasLeafs]

Don't they already have those? (The projected keyboards) I think they're called piezoprojectors or something.

 

[BShanahan14rulz]

Yeah, both technologies exist in fairly finished forms, and both technologies are in production products. I do not know why nobody has just combined both into one device.

You could use a small lipo cell to run the laser, just use the output from the smartphone to turn it on and off. You really don't need the phone to power it, just complete the circuit to turn it on or off.
