first hd2 mod-wireless charging

[reddog92396]

THAT'S NOT JUST REGULAR TAPE!

[mackhaio5]

why dont you try drilling some holes in the back of the case

[Mardigraz718]

You got some balls bro! You and that other dude are some mad scientists pioneers!

[RhoNYsEcigs]

hey, if you are still using this, it appears that powermat does not use the micro sd port. there are connections that it appears to use that is on the side of the sim card. This would mean that you will keep the port available while charging. good news?

[frozenphoenixprod]

You taped a coil to your phone. Congratulations.

[adamsy1]

how do you take out the mcro usb connector without breaking it

[TheBub1980]

Noob!!!

[BMXer053pc]

Don't bring that thru an x ray at the airport

[Winsucker]

Just a hint for your proj.

SEARCH FOR 3PIN PINOUT ON THE BACK OF THE PHONE (It's ment for car mount...yap-with charging)

[pgf95]

so the electric corrent is crossin the "air" trhought the phone?

[ICETEEBAG]

@pgf95 my theory is that this uses a megnetic field from the transmitter and is received in the phone and converted into electricity.

its kinda like a radio, the tower transmits energy, your stereo receives the energy and translates it onto sound, but in this case it doesnt translate it and just uses it as power.

[KiLLAdetox]

@ICETEEBAG no they call it wireless because you don't have a cord plugged into you're phone. the power board sends the electricity to the copper coil when they make contact.

[ICETEEBAG]

@KiLLAdetox @ICETEEBAG i didsnt say it would be powerful enough to do it from across the room. so technically my theory is still stable because the coil doesnt make contact, its separated by some plastic and tape.

[KiLLAdetox]

@ICETEEBAG electromagnetic induction, just like in motors. you could do it across the room but then itd be powerful enough to kill you :P

[pgf95]

@ICETEEBAG hmmm right.makes sense

[Winsucker]

did you tried using (striped) IDE cable instead of USB?

[blasko229]

Can you post some high res photos of the connection to the USB?

Does this remove your ability to connect to your PC through the USB?

Would like to try this on a droid. Thanks mate, nice job.

To the "why" people - What if Orville and Wilbur Wright listened to everyone who told them to just take the train? Cause it ain't cool. Duh.

[bugarim]

@blasko229 Then there wouldnt be any difference, as they werent the ones who invented the airplane =p Only americans think so...

But aside from that, I agree with you.

[MrBWatty]

Looks like an awful lot of work. Seriously why not just plug it in?

[srgymnast1]

@MrBWatty cuz it's cool =]

[droidclone]

Where did you get the coil from? I have been looking for them.

[l3v5y]

@droidclone I think it's from a palm pre touchstone. You can remove the coil from the backplate that comes with the touchstone.

[droidclone]

@l3v5y I was looking for the coils for another experiment. Seems hard to fine multi-layer small air coils.

[purchmonkey4life]

wonderful mod. please keep us updated on what you end up using in the end for a battery cover.

[DeadlyDad]

DealExtreme to the rescue! (I hope) dealextreme(dot)com/details.dx­/sku.40037~r.44625746

[jirka25]

lol :)

[tight686]

nice work dude

[l3v5y]

Great mod! The thing I'm wondering about is why you didn't use the connectors on the back of the HD2 (behind the batter cover).

They're designed for charging (can't remember the exact pinout) but it would be a lot neater. If I can get a touchstone, I'll try something like this!

[joman22]

@l3v5y I believe he didn't do it that way so he didn't void the warranty of the phone. Not to exact no that though.

[l3v5y]

@joman22 but you could blutack a wire to the contacts and not void the warranty.

[MAMeingast]

Nice!
