I recently got a HP Touchpad bundle and while the Touchpad is pretty darned decent and definitely worth a hundred bucks, what really impressed me was the touchstone charging dock. Its brilliant.

I looked into it and found the the palm pre also had this and some chap on the net had figured out how to shoehorn the unit into an evo.

I did the mod to mine and its amazing. No more charging cables. Yay!

This is my take on it - tutorial with pictures: http://asmd.wordpress.com/2011/09/26...-modification/

This should come standard in all wireless devices!

Nice mod! Looks better and I'm sure doesn't fail as bad as the powermat charger.

Hi, this is a great mod!

Noob question: I noticed the charging light but the charging icon does not change on your screen. Just curious if once that the battery is completely charged, the icon will turn green. If so I wonder if the charging unit from the Pixi will stop charging the battery once it's full.

Also, compared to charging it directly from the AC Adapter, how long does it take to get a full charge? Is it the same aprox?

I'm planning on taking a look at my Inspire and see if the back cover allows me to put the charging unit there.

Thanks in advance

I did this about a week after launch. Very cool...but over time the novelty wore off.

I got sick of the bulge and ripped it out.

Nice! I wonder if I do the same with the Powermat case...

I have the Powermat, but the only caveat is that it requires a bridge connector between the case and micro-usb port.

Im running MikG v2.5 Rom and the charging icon flashes between the lighting bolt charging icon and % so you can see at what % the battery is at while charging. When i took the picture, it was showing %, but rest assured it flashes between the two just as if it was plugged in the usb cable.

The Induction charging puck is dumb, it only supplies power much like a usb cable. The charging circuit in the Evo decides when the battery is fully charged and stops charging. The Evo for all intensive purposes acts and behaves exactly as if the usb cable was plugged in. It cant tell if power is coming from the puck or the usb cable. I wouldnt plug in the cable while its on the puck though. Although the voltage will remain the same, about 5 volts, the amperage will increase, a doubling in amperage shouldnt break anything but i havent found out the hard way.

The puck takes the same amount of time to charge as the usb cable. I havent seen any significant difference between the two.

There really isnt much of a bulge of the back case with using 30 awg wire. Just seat it flat and make sure nothing from the cover crimps on it, and its pretty much neat and tidy.

Ive seen this mod done with flat ribbon cable which would work just as well, although in not sure how it was routed through the phone.

30 awg wire or flat ribbon cable solves the bulge problem. Ive got pucks everywhere, several at home, several at work... and its great not to have to plug it in.

It serves as my phone holder and charging unit. i've set the phone screen not to go to sleep while charging, so it makes for a nice display as well. With the screen left on, it does take longer to charge though.

Yeah,

I did this a Loooooong Time ago using the Palm Pixi touchstone cover.

Here is what it looks like with a custom clear back cover.


The Pixi cover is substantially thinner than the Pre cover and can be fit easily without bulge.

It actually held my phone up hovering in the car while driving.

Its been done. Apparently its quite easy to replace the powermat induction unit with the pixi unit. and the cover fits perfectly.

I opted not to get the powermat case as i wasnt keen on the bridge with the usb dongle sticking out the bottom.

Ive havent heard many good things about it, pretty much nothing but complaints about the powermat induction charging unit which is why i decided on this mod and i can tell you it works, it simply works, perfectly every time.
