I'd like to modify a pen so its cap acts as a direct stylus. I'm thinking of taking a good pen, attaching a magnet to the side and a point composed of DirectStylus compatible material to the top with superglue then sugru for an ergonomic yet stylush finish. The neodymium magnet should allow it to snap on the smart case mounts.
I want the tablet to recognize it as a stylus as well as measure pressure like nvidia's does.
I've googled to no avail, just that passive capacitative touch doesn't normally detect pressure and somehow the direct stylus does.
What sort of material does the direct stylus use?

While I can't answer your question, I will describe my observations of what ELSE gets registered on the screen:
- keys. yup that's right, I tried using my house key and the tip is recognized. I suspect any metal tip would work.
- ballpoint pen tips. I was trying to trace an image from the screen onto a piece of paper overlaid on it, and the picture kept moving!
- my headphones cord. found this out by accident when i was watching youtube and my screen was moving all over the place. took me a whole 5 minutes to figure out my headphone cord was in contact with the screen, and that caused the movements. so I suspect the outer housing was thin enough that the internal wiring could still get detected by the screen.
The pressure is definitely not detected in the Stylus though. It's just a passive stylus with no internal electronics at all. For pressure, you'll want to use a material that can deform, since I think that is how the screen detects it. More pressure means the initial size of the touch increases a greater amount.
Confirmed: http://www.slashgear.com/nvidia-shield-tablet-directstylus-2-review-29338977/
"NVIDIA’s DirectStylus 2 is arguably a similar compromise, but it’s a clever one. The pen itself is regular plastic with an angled rubber tip, and the magic is all in the software and algorithms. Running the touch processing through the Tegra K1 means it’s able to differentiate in real-time between the nib, your fingers, and your palm resting on the display. DirectStylus 2 can even feign pressure sensitivity, by measuring the contact point as the tip deforms against the screen."

I was thinking of attaching a tip on the opposite end of the scribe pen so that I can turn it backwards and use it as a touchscreen stylus. Any suggestions as to what would be the best item to use. I know on the ones I have seen in the stores the tip has a spongy bounce to them but the are a rubber material.
Capacitive rubber comes in sheets or tubing. There's also capcitive foam, but it won't be as durable.
The trick is the adhesive, you need to male sure enough of the material touches the aluminum pen.
Or maybe plastic film protector for the screen, which seems to conduct electricity.
Thanks for the info. It is too bad they didn't fix the other end of the pen to be used as a regular stylus. If I find something that works I will post back here with it.
I'm also looking for such a conductive rubber thing for the other end of the pen. I think a ideal solution would be a conductiv rubber tip or something similar which can be pulled over the end of the pen and sits tight (could easily be removed for battery changes). Unfortunately I haven't found such a thing til now.
Someone at XDA did find a capacitive tip which they were able to stretch over the cap... I forget which user, but it was in one of the early threads. Maybe the wacom capacitive stylus would work, it looks like the proper diameter.
Two suggestions
I have 3 (edit) suggestions
1. Buy a cheap stylus, cut off the capacitive head and afix it to the top of the HTC pen. I found these at $2.60 for three. You have 3 tries to get it right.
http://www.amazon.com/Universal-Touch-Screen-Stylus-Silver/dp/B002BBJMO6/ref=sr_1_1?ie=UTF8&qid=1311768442&sr=8-1
2. Ideally, if you can find a metal cap with a capacitive head that fits over the HTC Pen, you would have an elegant solution. If something like this fit, it would be great.

I found this too: http://www.kickstarter.com/projects/1004382302/more-real-stylus-cap
edit #3. this just in... What about this touch tip? http://store01.prostores.com/servlet/truetip/Detail?no=48 - (edit #2) NOPE these are NOT capacitive caps. sorry
Maybe I'll experiment with my back up fujitsu pen.
hmmmm
From the TrueTip website...
*TrueTip styli currently only work on resistive (pressure sensitive) touch screen devices.
Our styli do not work on an iPhone, Droid or similar conductive touch screen devices.
We hope to have a stylus solution for these devices soon - Please check back!*
I have one of the 2-in-1 pens fory iPad and they do work... The problem is that you would be carrying two pens for your device, which is what this thread is trying to solve.
I briefly read that the Sharpie marker caps seem to fit the Scribe pen. They make a metal version of that marker, but then you're back to metal on glasss... But would probably be easier to wrap with plastic film.

I am not sure I explained myself well. I meant if it fits, take the stylus cap off the 2 in 1 and put it on the flyer pen. Then you will be carrying one stylus that serves both functions.

Ok. So I should probably clarify, my pen 2-in-1 is the push button type which allows the tipto be retracted.
I like the kickstart product... In your post.
It seems so simple.
A simple plastic clip with an adhesive back so I could clip my pen top edge of the screen (where the HTC logo is) when I'm not using it.
Would be SO helpful yet no one makes one. HTC are you listening? How hard would it be to include this with the tablet? Or how about with the pen you charge a fortune for?
I am going to look around. I bet something like this exists for holding a pen to a dry erase board or something and I can adapt it to the EVO.
Have an idea.
Think I'll just get a simple piece of black leather, cut a small strip, wrap it around my pen for fit and stick the ends to a small piece of double-sided foam tape. then just stick it to the top front of my View (where the HTC is) and presto, pen holder.
Or even easier, get a long thin strip of velcro and stick it along the top front of the tablet, then take a long strip of the soft fuzzy side and stick it to my pen. That should hold it pretty well while I'm typing on the tablet.
Another solution I have found is to add a cap with a clip to the back of the pen (a sharpie cap fits perfectly). Then attach this to a tether that fits into the headphone jack (many capacitive styli come with this tether). The pen dangles a bit, but what the heck, it is safely attached.

Thanks. Yes, I thought of this as well but i hate the dangling pen part. Will post photos of whatever I come up with.
Not sure if this helps you in your search. I use a clip from a 2 dollar in line air blower or a pencil tire pressure gauge … fits the pen perfect.
Here’s a pic http://dl.dropbox.com/u/5220128/clip1.jpg
I have my flyer in a Blurex case and the pen snaps onto the closing latch.
I could have gotten a case with a pen holder. The problem is that I use the note app to do some.pretty hardcore thumb typing as I'm on the phone. In order to fly the tablet has to be comfortable in my hands. This means no bulky case so I just have a simple protective case on the back and no pen holder.

google pen pal -- Slim rubbery pen clip holder with adhesive
I think they have them on amazon
cheap too -- 5 in a pack for like $4

Thanks for the lead on that. I want a black one and it seems they are selling every possible color except black. Oh well.
In the meantime I've come up with a simple solution that has the benefit of not adding thickness to my tablet when I put it in it's sleave or in my pocket.
It is just simply some velcro tape applied as show in the photos. Works a charm.
Thanks Kudzus for your idea of the tire gauge pen clip. It works perfect for me. Thanks!
It didn't scratch the finish off your pen like one of the other members stated?
I now have the screen and stylus set up where I can draw decently on the Prime, but am having issues with palm detection. I have the app TouchScreenTune and have palm rejection on, but it still registers it sometimes.
I was wondering, is there a glove or partial glove that prevents palm detection? I know that any glove with non-conductive materials should do this normally, but I have been able to have access the screen even with these.
What do you all do normally to stop palm detection?

I know this isn't the most helpful answer but:
Don't touch the screen with my palm.
If you are using an app like TouchScreen Tune to crank the sensitivity of your screen to increase performance, maybe turn it down a bit. If I put a thin piece of cloth over the screen none of my touches register so I don't know if you are doing something different that makes the screen work through your glove.

What a novel idea!
I used to have a windows tablet with an active digitizer and didn't have to worry about anything showing up except the pen. It's just something I'll have to train myself to watch out for.
I just got TouchScreenTune last week and am still tweaking it, so that might take care of some of it. I have Sketch Book Mobile set up now so that diagonal lines are smooth and not stair-step shaped and it seems that the Prime will make a decent sketching tablet.
I had thought of this as well while testing out stylus and hand written notes. Just to test the theory I tried with thin 100% cotton t-shirt. Two layers of that material and touches were totally blocked. My thought was that if you had a cotton glove of thick enough material it would be perfect. Also you could either cut off the fingertip of the index finger of your writing hand or replace it with touchscreen friendly material so you could still do finger touches on screen with that hand. I know I've seen companies selling thin touchscreen friendly gloves before so you could cut a fingertip off one of those and sew into the cotton glove perhaps.
Buy some cheap gloves made of thin material, cut off the fingers.
You should not register touches with light pressure by the palms. Take a piece of paper and place it over your touchscreen and see if that responds at all. It barely does with my phone and I was stabbing at it with my fingers.

Er... this is the exact thing the OP does not want.
I've used winter gloves with the fingers cut out... I can put pictures up if anyone wants.
The problem is, it depends on your set sensitivity. If you have the touchscreen sensitivity app, you can adjust the sensitivity and the problem for me is that when I increase the sensitivity so that it works best with the Adonit Jot Pro... the screen actually can pick up my palm through the gloves.

It's actually exactly what he wants. Why would you be touching the tablet with your palm?

The point is that for handwriting like you would with pen and paper palm rejection sucks on the ATP. By having a thin insulating glove you resolve this issue. And with the right glove material you could clean your screen while writing.

Which is what I was thinking. I'm going to throw something together this weekend and see how it works. Its not a life or death kind of thing. It would be nice though to draw on this thing like you can with paper without acting like the screen is lava.

Okay, well that's a result.
I turned TouchScreenTune off, grabbed a cheap knit glove and a screen cleaning cloth, quick stitched one to the other, and tested it. Through the cloth and glove, the screen is still picking up palm touches. Which must mean that the cloth I used is capacitive in some way.
Meh.
You should buy the stylus handpad. It do just what you want, and come with a stylus pen.
I think it's easier and more conformable to put on compare to glove, especially in the summer time.

Hello Android fans,
I'm a new user to the Samsung Galaxy Tab 2 10.1 from T-Mobile (SGH-T779), and I wanted to discuss my case and screen protectors of choice I like.
First of all, my screen protector of choice in most cases is usually Zagg's invisibleShield, because it works REALLY well, most of the time. I say most of the time for reasons not related to this situation. I have a Galaxy Note 2 as well with a wallet case that presses against the screen, Zagg's plastic technology doesn't work so well for it in that kind of situation.
Otherwise, my Tab 2 has a nice wet-applied Zagg invisibleShield HD screen on it, and it's plain awesome. There's no quality loss in the screen, it doesn't scratch very easily and doesn't collect a whole lot of fingerprints. It does collect them, but easily wiped off with a simple cloth.
My case I'm using, though it's not /perfect/, it's just currently the best I could personally find at the time.
It's the RooCase RC-GALX10TAB2-DA-BK Dual-Axis leather folio case. Basically it works using a 2-piece assembly. The main part holds the case in a nice felt-feeling case, so you can hold it, without the outer case, in a night light package. The outer case has velcro to hold the inner part to it so you can rotate it by sticking it to the velcro. This allows it to be in landscape or portrait mode very nicely, and it doesn't fall over when in portrait mode like a lot of the other dual-axis folios seem to have a problem with. It does use a low-powered magnet on the front of the inner case to the outer inner case so it snugs together when closed.
The only downsides are, so far:
The stylus/pen holder is on the outside edge of the outer case, so it sticks out like a soar thumb, and can easily be knocked out.
The case has no hole on the bottom side for the 30-pin connector, though this issue can be kind of gotten around by simply rotating the tablet to its side, or completely upside down, thanks to full auto-rotation of the Android interface. I usually plug it in every night in this manner, rotated out to put the 30-pin on the outer side and plugged in.
It is "technically" leather, but it seems like every other "Genuine Leather" product out there, where the leather is just a very very thin layer of leather covered over cardboard or other fillers. (I make leather stuff as a hobby, so I know what real leather is capable of and feels like when done properly).
The plus sides are:
It fits rather well and does not interfere with the touchable screen area, even with my big hands I have yet to conflict with the edges of the touchable screen. .
It fits very snug and tightly, so it doesn't move at all.
It fully exposes the power, volume rocker, microSD slot, IrDA port, and headset port, and covers most of the SIM card, so it helps prevent loss of the SIM card in case it ever popped open and somehow snapped out.
Anyway, that's my review, hope it's helpful to people.

Hey I'm looking for a case with a hard cover that doesn't bend - like a keyboard case or a case with a kickstand. It also MUST attach to the tablet in a way that allows the tablet to swing freely but it doesn't matter if it's via magnet or hinge.
It doesn't matter if it has a keyboard and the quality of the keyboard doesn't matter as I won't be using it.
The Zagg Folio 8" Auto-fit looks perfect - except it's WAY more than I want to pay. Can anyone please recommend any other cases that are lower priced? The feature that I need is a non-bending cover that attaches well, anything else like keyboard or looks is unimportant. Thanks!
Reason I need a non-bending cover is I want to hang the tablet so it hangs on a monitor with the cover portion laying flat on the top of the monitor so it's at eye level for use on a stationary cycle and so the monitor screen is covered. The two bendy covers that I've tried this with "collapse" and the weight of the tablet drags off the top.
I have an idea: Why not use Velcro stickers so it can hang of the top(back) of the display unit itself? It would be way cheaper if you already have something in mind and can be easily removed. And even the slimmest stickers could be left on the cover without interfering with the screen once it's closed or when held while in use.
Nice idea but it's for a machine at my gym.
