Q&A with the HTC EVO Touchstone modder
UPDATE: Tutorial now available!
Interested to know more about how YouTuber infinitemods got his HTC EVO 4G to work with the Palm Touchstone wireless charger?
I contacted him yesterday to ask if he might be interested in writing a tutorial for us here at G&E. I knew he was busy from a comment he left on YouTube, so I also asked some other quick questions that I hoped he could answer in the meantime.
He got back to me this morning and said that he would love to put together a tutorial for us as soon as he had "a few solid hours" to himself. To hold us over until then, he sent along the answers to my questions, all of which he typed on his EVO while on a lunch break.
How long did the mod take to complete?
The whole project took about a half hour, but it can be done in about 5-10 minutes.
Did you run into any problems while trying to get it to work?
There wasn't a whole lot of trial and error. I just used a multimeter to find the proper contacts on the board. Despite what most people think, the contacts from the induction coil DO NOT go directly to the battery contacts. You could damage the battery and possibly the phone like that.
Are there any drawbacks to the mod?
Neither of these bother me, but they might bother some people.
- The 4 magnets around the coil render any compass apps completely useless.
- The battery cover sticks up a little but as you saw in the YouTube video it's barely noticeable. I could probably make it fit better but I didn't want to modify the internal plastics just in case I ever have to return the phone.
How does it handle heat?
I've left the EVO on the Touchstone every night till morning and I haven't noticed a whole lot of heat. In fact, I felt more heat charging the phone using the micro USB cable or just through heavy use.
Anything else you'd like to share with us?
Thank you for your interest in my mod. To the best of my knowledge I'm the first person, if not the only person, to do this mod but I hope there are others out there trying it out for themselves. I will try to get a tutorial to you ASAP.
