Mirror Screen (sort of like "heads-up display") - Windows Mobile Development and Hacking General

Hi all,
I'm looking for a way to mirror my screen.
I'd like to put my Kaiser on my dashboard in my car, and in the reflection of the windscreen, see my TomTom-directions...
Not because it's urgent, just because I'm wondering if it can be done
(sort of like why elephants break down trees; "because they can...")
Any pointers are appreciated!

how do you fix it in the cockpit?!

I have a rather horizontal spot, just in front of me, on the other side of the wheel. The rubbery cover of the external GPS-antenna keeps it in place (as long as I dont take coners too fast). I now sometimes have it lying there, but it's a bit confusing, especially when I'm on the phone (and sounds are muted...)

Well...I think this is not a good Idea...if you don't fix it on the cockpit it may fall off...That's dangerous, because you're distracted at this moment...

Poor build quality.

I see other people have posted the problem with the stylus coming loose over time.
I also noticed today that the paint inside the ie button and to a certain extent the messaging button (the buttons above the screen) has been removed, it seems due to taking the device out of the holder all the time.
Anyone else think this is realy poor
Paul
yes i too think its a little lack-lustre.
the internet and messaging buttons logo's have both lost 90% of their paintwork.
i think it wont be too long until my keyboard becomes a little too easy to open. after all its only two little plastic notches which cause it to "snap in and out" once they have worn down a little then its gunna get ugly

Is that true ? I am going to buy one, you talkng about Qtek9100 or K-Jam or both???
i have kjam, but both are the same in terms of build
heres a cross section of the slider in action... when you pull it out the little notch "snaps" into the recess.. and the same when you close.
seeings as its just plastic i have a feeling that that will eventually wear down with use. i already think its become looser than it used to be from only having it a month
I have the qtek 9100 and do not have any oif the problems described above .... yet!!

Hermes Keyboard

Hi,
I am just checking on my new Softbank Hermes
Just noticed that the keys the farthest right of the keyboard are little bit deeper (or sunk) that the ones on the left...but they response perfectly.
Are your unit the same ?
Thanks
anyone ? I have 3 days for exchange ..
I have an HTC Tytn and my keyboard is not like that.
My T key has a big oval of paint scraped off of it, and the backlight shows through, seems the center of my keyboard had a hump in it.
If you can exchange it, I likely would.

Internally the Hermes has on one side of the keyboard (can't remember if this is shown on the wiki pictures) a foam rubber block running from the qwerty row down to the spacebar row. At the opposite end this is absent as internal parts make up the gap. It does not surprise me that there is some uneven-ness in external appearance though this should be very minimal. If your keyboard works perfectly I'd hang onto it given numerous reported problems with unresponsiveness of keys.
My keyboard if anything is a fraction higher in central area but not so high it scrapes on screen assembly.
Mike
Hi Mike,
Thanks for the tip...
Browsing from the pics, youre right, the left side has this foam block and the other side has none. That's why the keyboard is high on the left side and slowly sinking going to the right...(around half of millimeter..)
My unit is working perfectly, and I dont want to change it if the unit would be the same.... it might be the design ,...

Quite right would be a gamble. Was just about to guide you to pictures just as you replied saying you'd seen them!!
Mike
Dont know why you have a hump on the center part of your keyboard...your foam block might be in the center in your case ?
I also saw that the keyboard PCB is fixed by a clip on the right and a black thing on the left side...do you know what's this thing ?
so...there a way to "perfect it" by putting a slightly thinner foam on the right side to equalize the pressure...
Do you have a pic on how to do it ?

Screen Rotation

Hi All,
I have updated to the latest AKU3 ROMs and also a few months ago I replaced the housing...However, I've noticed that the screen does not automatically rotate when the screen is swivelled??
Now is this because I did something during re-assembly of the housing OR is there something in the ROM's that disables the hardware somehow??
Cheers
ODY
Unlikely to be the rom, since it's part of the system HTC provided.
If it's been disassembled it's more likely that.

hey VJ, sorry to bother but do you know what jumper/cable/connector/switch to jump/disconnect/tape inside the Universal to keep it from switching?
I'm sure I saw someone mention that the screen rotation is done by a magnet and switch? It's possible that maybe a small magnet fell out during disassembly? But I have looked throught the Universal repair manual and I can't find any reference to such a magnet??
I'd be nice to know exactly where it is so one would be able to take it out, if it were easy. I don't know if I wanna disasemble mine yet...
EDIT found it!! If you use a very, very light metal chain, as I did, with a keyring @ end, you can hover it around the Universal and see the tension of the chain when it's near the magnet. the keyring sticks too!
it's on the lid, behind the video-call video camera. I'm going to check the lid part of the manual.
Well taking the screen section apart is easy! You don't have to disassemble the whole unit. Looks like my magnet fell out then! Trouble is I want to sell mine so I'll just have to declare the auto screen rotate doesn't work (I've made sure that there is the rotate screen icon on the task bar though!!)

it works!! I tested it with the very small and highly magnetic point in the bezel of my tablet PC (to hold the pen) and it did change orientation.
thing is that it seems to be stuck beside the sound-holes (when the unit is closed).
I wonder how could I disassemble the lid only? are none of those screws @ the bottom connected to the back part of the lid? if so, that would be awesome!
Hi, on the xda's ftp, you'll find the maintenance manual for Universal...may help you to disassemble yours
thanx for the link!
however, it seems rather risky to try to pry the bezel open while still on the unit. Anyways I'm doing it right know. I'll get back to you.
I did pry it out and took the magnet off... painless(*) procedure and flea-sized magnet! don't loose!
I took a couple of pictures detailing the magnet position and the lid disassembled while still on the unit.
if you want to do this procedure do not loose the tiny screws and...
(*) be careful with the outer speaker (the one that lets you hear a call while the screen is facing the keyboard when closed), it isn't hard wired, it's just two small and fine contacts that might get distorted when putting the lid cover back... I had to take mine out again to correct this problem.
also, be careful with the screw driver and digitizer, as you'll be working in very akward positions to avoid disassembling the whole unit, and take off the battery of course.
Thanks for the photos - looks like my magnet feel out so I bought some 1/8 inch square magnets from ebay. It took a couple to find the sweet spot where the screen rotated but at least it works fibe now!

no problem. I'm also going to put the magnet back, now the unit doesn't now when it's closed, and therefore the outer speaker does not work. the screen also does not turn off when closed, only when the system timer tells it too... oh well.
you can turn the screen off by pressing the power button briefly.
no ext speaker though! maybe there's a way in software to disable just the rotation; i think the guys trying to get linux comfortable on the universal have some experience with it, maybe they can help.

O2 EXEC - Screen A little wobbily

Hi
I have a very much loved o2 xda exec, however when you have it in 'laptop' mode so to speak - the screen part of it wobbles if you move it, it looks like it's something to do with the swivel part between the screen and the unit, currently it's not too bad enough to make me think it's not right - It used to be tight and not do this.
So I was wondering is there an easy way to fix this? I would hope that it is just a screw inside that needs tightening??
It would be great if anyone could help out a fellow xda user
Thanks
turn the screen through 90 degrees. Look down on the hinge and on the left hand side you will see a tiny screw. Tighten this, if necessary, add a little locktite to the thread.
thanks this solved my problem also.

Magnet attached at the back cover

Hi all! Im in love with this community from day 1
its my 1st thread though seeking for help/advice/your superior knowledge
Thing is that i want to mount my phone in my car using a small magnet attached somewhere at the dashboard and stick my HD2s back cover which is metallic...
my question is: is it possible because of the nature of the magnet to cause problems in the phones operation?? like radio interference or something like this?
looking forward to your answers
i think a magnet may interfere with the touch screen. not positive on this but am sure i`v read somewhere about tiny magnets being in the tip of some capacitive screen stylus`s. a stronger magnet to hold a hd2 would surely result in some type of touch screen interference. but like i said am not a 100% certain.

magnetism will not affect a capacitive touch screen. It will however mess about with the compass!
A capacitive Touchscreen works like a capacitor, whichs field is "spread" over the surface of the screen. By tapping you will change the the resistance of the oscilating resonant circuit, which has a specific resistance (which is related to the dielectric medium, which is changed by your finger)
With this, the phone is able to locate your finger in X + Y axis to find out where you have tapped.

Yes, obviously it will but thats the least of my worries as it wont be permanently attached to the magnet and the times it will, i wont be needing the compass app.
so if thats the only problem i think im gonna give a try to this project...

Does this mean that a magnet at the back could interfere with the circuit of the screen? and if yes i guess is temporary right?
waiting for more thoughts/input on the subject

this is school knowledge...
after some trial and error i found out that the back cover of HD2 although it looks metallic apparently its not coz it can't be attached to a magnet...
That would only mean that it is not made of an iron compound

magnet
I think it is made from stailess steel.magnets do not work on S/S.

Is that true? I know old compasses relied on a magnetised needle to work, but I thought the compass in the HD2 got it's direction from the GPS and the accelerator software??? How would a magnet affect these?

no it's a dedicated compass hardware
Actually, even my notebook apparently hurts it! Looses calibration
yes several times when i opened the compass application arround various interferences it asked me to move it in the usual 8-like movement to calibrate itself..
what about the rest of the phone and memory and SD card wouldnt it affect the storage ? i clecned out my speakerphone with a very small magnet yesterday to get all the lil pieces stuck on it.
and after that my phone(touch pro2) completely froze up and kept freezing up after first input untill i did a hard reset.

i did another little test with a small round magnet around 2cm diameter. i moved it around the back of the phone while looking at the screen and i didnt notice any interference to the screen, at least to my eyes it looked like the magnet did not interfere with the phone at all.
However i moved the magnet to the screen and tried to touch the screen gently with the edge of the magnet and the screen responded immediately and it looked very precise too! i did several presses to the screen with the magnet and in all of them the screen responded exactly as it should, just like it should with the press of a finger, i even wrote some letters as text and it worked great. so i guess thats how they make capacitive stylus..
next time im gonna try to draw on notes application and see how precise it is on that.. (as long as i find a smaller magnet that i can handle better than this one)
i might try to make my own capacitive stylus....
why not....
I have attatched a magnet to the back of my HD2 so i can use my vent mount, i havent noticed any adverse effects.
