Passive vs. Active Stylus.

This idea of an "active" stylus (using some current) to boost the sensitivity interested me, so here's the experiment I did. First, tried, but was not able to reproduce your results of using the power cord on either my charging phone or nook to get screen taps.

My setup is; CM7 nightly 202 off of the SD card on the nook, and I used Sketchbook Mobile for these drawings (free from amazon a few days ago, link)

Here are conditions this was done under. For stylus, I used;

Finger: Human finger

Passive: A passive stylus, using the corner of a piece of conductive foam (used to insulate IC's)

Active DC: The same foam corner with a couple of wires stuck in it. They were placed about 2-3 mm apart, equal distance from the nook screen when it was pressed into it. The foam resistance measured across these was ~200-300 k Ohms. Through these I ran 1.6 V (1 AA) -> ~8 micro Amps.

Active AC: The same foam and wire pairs, but now I ran the output from the nook's headphone jack to the wires (I used ground and an active pin). I streamed pandora at the highest volume for the AC source (easiest I could think of, since I don't have a function generator).

For each case I dragged it across horizontally and vertically at differing pressures;

Brushing - barely dragging the stylus across the surface

Light - what I would consider to be normal use

Medium - a heavier press

Heavy - really pressing down on the touchscreen

I did the best I could to use the same pressures throughout, but I only have a rough humanoid force feedback gauge built into my fingers.

Here are the results;

These results were highly variable and not vary consistent. I'm concluding from this that;

These things are really optimized for human touch and/or we're really good at screwing up capacitance.

Pressure is a better indicator of getting reliable touch events than current or current type.

Regarding the second item, it would be interesting to see if the foam density has an effect: when I was pressing harder, the foam was compressing more and the increased density was giving the greater effect. Also what sort of effect area has on the sensitivity: again a harder press is correlated to a greater area in contact with the screen.

I'm interested in what other ideas everyone has for making a good stylus, or if there are any comments / questions on my methods.
[Nook Color Accessories] jgaf:
From the experience I had making the stylus, the increased density has an effect. Mine works good since it has like half an inch of area, and about 1/4 of an inch width. I tried doing it as small as possible at the beginning, but that didn't, although it was flawless on a ipod touch 3g. I would love to see someone try it on a Nook Tablet
[Nook Color Accessories] Modded Darts:
Cool tip is it cost effective though.

New video

Hello, here is another video a made of the stylus. This time I used screencast app to record the NCs screen, I recorded at 25 fps, and then raised the video's speed on my PC to 1.40x so it would look natural. Anyways this further proves that a good working stylus is possible in the NC, although of the not so good screen response. Also I'm using a different app for taking notes called Genial Writing, it seems to work a lot better than Handrite. I also tried using the stylus on SketchBook Mobile (not on video), it works pretty good for crappy drawings, nothing to detailed or complicated, since its kinda hard to make perfect lines or circles.

Yes my handwriting kinda sucks :P
[Nook Color Accessories] gallahad2000:
Too bad none of the cases have styli slots, although it would be easy enough to attach to the nook's loop.

[Galaxy Tab Q&A, Help & Troubleshooting] jaydee24:
So please excuse my noobness on this question. I have a galaxy tab 7 inch tab for t mobile. I have rooted the tablet but I am having a hard time putting roms on the device. I have rom manager but I want to know what is a good rom that I can install using rom manager. Are there any honeycomb roms. Im new to this so is it much deeper than using rom manager to put them on the device. I know I have to have clockworkmod installed. Thanks for help or suggestions in advance :-)

Nandroid backups on the D3 aren't the fastest right now, but with a simple and quick tweak, we can make them much, much faster.

During the backup/restore, clockword recovery shows each individual file being copied. By turning this off, it drastically improves backup/restore times. It'll still say backup up /system, or /data, it just won't show the individual file. In order to remove the nandroid progress stats, you need to create two files using adb or terminal emulator.

ADB or Terminal Emulator​

1) type- (may need to do "adb shell" first)

echo "" > /sdcard/clockworkmod/.hidenandroidprogress

Press enter

2) type

echo "" > /sdcard-ext/clockworkmod/.hidenandroidprogress

Press enter

3) Done!

Hint- to check to make sure it created the files, navigate to /sdcard/clockworkmod and see if there's a .hidenandroidprogress file. Also check in /sdcard-ext/clockworkmod for the same file.
[Motorola Droid 3] eXecuter.bin:
Can't we just create the files manually instead of going through the trouble of using adb?
[Motorola Droid 3] MrObvious:
Yup. I used a terminal emulator on my phone since I didn't feel like taking the time to do it.
[Motorola Droid 3] limaxray:
Thanks for this. I was wondering why backup/restore was so much slower on the D3 than on my OG Droid - synchronous IO strikes again.
[Motorola Droid 3] Hashcode:
FYI,

I removed the detailed progress bar from the upcoming Safestrap 1.0. The wait was just too long to even have that option enabled.
[Motorola Droid 3] g3m1n1:
Excellent post, thanks a lot for sharing this tip.

Edit: I created both files and then rebooted into Recovery and started a backup. I still see each file being named as well as the progress bar. Did not seem to work for me... :(
[Motorola Droid 3] erismaster:
You'll still see the actually progress bar. It just won't show each individual file. But that's weird. Ill see what I can find out.
[Motorola Droid 3] g3m1n1:
Definitely weird, I will delete the files and try to create them again to see if that helps. FYI, I used Android Terminal Emulator to create the files using the commands you posted.
[Motorola Droid 3] erismaster:
Did it actually create the files? try using /mnt/sdcard/clockworkmod/,hidenandroidprogress
[Motorola Droid 3] g3m1n1:
:o Wow, had a temporary lapse of reason earlier... Your typo of the comma in your last comment made me realize my own typo in typing /.hideandroidprogress instead of ./hidenandroidprogress . Backups are much, much faster now.
[Motorola Droid 3] Bobbar:
Huge difference!
[Motorola Droid 3] Wolfhere:
YUP. Same here. Smooth
[Motorola Droid 3] 7April:
Nandroid is ripe for a rewrite anyway.
[Motorola Droid 3] MerCiLeSS28:
How do you make a nandroid backup to begin with?
[Motorola Droid 3] erismaster:
You boot into clockwork recovery and click backup and restore and then backup...
[Motorola Droid 3] Camspanners:
At first, wondered why I couldn't see them with ls...

With terminal emulator, at least, you have to use "ls -a"!

Cause its not 'hidden' but 'hide android'
[Motorola Droid 3] erismaster:
Hide-nandroid-progress actually :D
[Motorola Droid 3] matthskim:
How do you save these files? Is there a command upon finishing typing or is the file created upon exit of the terminal emulator. I am asking because I just tried it and there is no file in the directory.

Thanks.

Edit: done. I did not press Enter
[Motorola Droid 3] Rotkaeqpchen:
Please test if restoring a backup works. Because it didn't work for me and I assume that this happened after doing this mod. When i removed the file the backup could be successfully restored.

Please report. :)

[Samsung Epic 4G Touch] timinator94:
Ok, So I am incredibly unsatisfied with Sprint's service as of late. I purchased the Epic 4g Touch and experienced the dreaded "Loss Of Service" bug frequently. I was within my 14 day return limit so I went into the Visalia California Sprint Store to swap out for a different model (namely the Evo 3d which I traded in for the e4gt). I also signed 5 of my friends up with sprint as well and 2 of them got the e4gt and had the same exact issues. They convinced me to try a replacement and assured me that if it still experienced that bug I could return it within 14 days of receiving the replacement phone. The replacement phone was worse than the one I had originally and lost service every hour. I missed several calls from work leaving my employer under the impression I was angry and ignoring her and almost cost me my job. So I went in to the Visalia California store yet again to get a replacement model. I spoke with the same woman that convinced me to get the replacement model (She was also the manager) and she stated that the device was out of its 14 days since the FIRST device and that I couldn't get a different model (see what she did there?). So I went home and called Sprint off of another line and spent 4 hours total on hold. I hung up and called Sprint tech support and after running tests and walking me through updates and such the rep spoke with a manager on his end and concluded that I needed a different model of phone. He stated that he would note that down in the ticket and to go into the Visalia California store and they would give me a different model. So I went in to the store and spoke with the manager yet again. This time after reading the ticket she became rude and uncivil stating that the ticket says "customer needs to try a different model of phone" and that they didn't have to provide it for me and that even if it did, corporate cannot make them give me a different model. The whole time I was civil and polite but my frustration was building. I drove an hour to the Sprint store in Fresno only to find out that Visalia had to handle my case and that they could not even replace it with the same model. So I found a man on craigslist and traded it for a Nexus S 4g. I plan on paying out my contract asap and switching to Verizon. They know how to treat a customer.

/End rant/
[Samsung Epic 4G Touch] LancerEVA06:
Call account services, and speak with a manager. They should be able to escalate a claim. Or at least do something more for you.
[Samsung Epic 4G Touch] timinator94:
Account services was the first call I made. they would transfer and drop me. This literally happened 12 times.
[Samsung Epic 4G Touch] poppygt:
Wow that's crazy. Sprint is actually really cool here and if there's notes on your account the corporate store will always honor what they tell you on the phone. They even replaced an Evo with a bad speaker that my buddy had bought at an "authorized retailer" AFTER his 30 days were up.

I'd fight them so hard on this. Look for any sites that rate local businesses and flame that chick like there's no tomorrow. Also threaten and follow up with a complaint to the BBB. You don't have to take that treatment from anyone.
[Samsung Epic 4G Touch] timinator94:
I already traded my phone to someone else so I doubt they will do anything for me.

But yeah I will report them. didn't have to deal with sh*t like this with the big red
[Samsung Epic 4G Touch] tinybfk:
Yeah probably a little late since you traded for a nexus. You could have at least sold the e4gt to pay the early termination fees and just left sprint.

And yeah I needed a working phone asap so at the time it seemed the best option. I can pay the fees I just refuse to. I tried to pull that card and they transferred me to a manager which i was conveniently disconnected from in the process.

Activate a new account with a 2g iPhone. Do the activation thru iTunes and select unlimited data, wait a week it so and switch your sim to the phone you want the unlimited data on and call care and update the imei .

I thought California required a 30 day "trial" period :confused:
[Samsung Epic 4G Touch] :
Apparently not..
[Samsung Epic 4G Touch] Lonewuhf:
No offense, but this all sounds a bit exaggerated. I've been with all 4 of the top companies and Sprint has by far the best customer service. The rare few times I've been disconnected when I've called they've called me right back. I've never had a problem replacing any defective phone no matter how long I've had it, and Sprint seems to be fairly generous with discounts and refunds even while having the cheapest plans.

I think the manager at your Sprint store is out of the norm. The people at my Sprint store are more than helpful and willing to solve any problems. If all of this is truly genuine and not exaggerated then that sucks, but this isn't typical at all for Sprint customer service, at least in my experience. I've been with Sprint for 9 years now.

It's too late now that you've traded in your Epic Touch, but if you have a problem next time I'd suggest calling retentions. They'll do pretty much anything to keep your business.

p.s. How did you not know that both AT&T and Verizon are tiered? It's been that way for a while and is one of Sprint's biggest advertising campaigns. Oh, and the suggestion on how to get unlimited again from this thread will no longer work, just a heads up.

Sprint has always been extra helpful with replacements, free extras, repairs, etc. Oh OP, kick ass job on the ICS ROM for the Nexus

[Samsung Epic 4G Touch] daryelv:
I'm in the same spot as you, I've been requesting a different model since day 12 after buying my first ET4G, I got a replacement for my original ET4G on day 5 and still had issues so I requested a different model. I've spent countless hours on the phone and in chat with Sprint Technical support, Sprint Customer Service, Sprint Account Services and their "ACG"? team with no resolution. I've spelled out that I'd like a different phone or to be compensated for the Loss of Service that I experience with this phone. So far I've gotten nothing other than "I'm sorry, but an update is on the way..." I opened a case with the BBB and will let them handle it.

Maybe if the BBB got enough complaints about Sprint handling this issue it would put a little more priority in getting it fixed. The other option is to start a class action lawsuit as those seem to get visibility from all the bloggers.

Visalia is a corporate store. Do non corporate sprint only stores exist? Its where I bought my phone.

We have to live in the worst area for LOS. I get them constantly in the visalia/Tulare area. I almost never get them in San Fran, San Jose, LA, San Diego, Thousand Oaks...pretty much anywhere with decent coverage, which ISN'T here in Visalia/Tulare and surrounding areas.
[Samsung Epic 4G Touch] Ranger093:
Verizon doesn't know how to treat a customer. Become one and you'll quickly see the difference. Have fun with that....
[Samsung Epic 4G Touch] sfhub:
This is pure BS. For online orders you need to request the return within the 14-day period (actually 13 days since they count the first day). Then you have 30 days to get the phone back to them before they charge you full price.

If they did it as you were told, you basically have 0 return period. 4 days from order date to get your phone, 5 days for return kit, 4 days to deliver the phone back to their processing center, 13 days (14 days counting the first/order day)

I guess in their fantasy world, you could order the return kit a day after you place your order, and that would give you a few days to actually try the phone and still have a return period, but then they would cancel your service.
[Samsung Epic 4G Touch] TooSlo:
You can see how I'm frustrated as a consumer.

I honestly wasn't going into this purchase thinking the problems with the device would be so problematic, or that my ability to replace the device when a problem was found (LOS is a problem in my book) that nobody would want to take care of me as a customer.

Some people may say that my expectations are unrealistic. I would say that while I have high expectations of a service provider, I've worked in support services long enough to know that what I'm asking as a consumer/customer aren't pipe dreams. I'm not asking for a second phone, I'm not asking for months of free service to make up for the time I haven't been receiving calls.

In the end, I want someone on Sprint's end to empathize with my situation and help find a solution that keeps revenue coming in through my account, and provides me with a device/service that I need. Right now I have neither of those, and it's unfortunate that the best resolution in this case is to port my phone number that I've had for 10 years to Google Voice or a pre-paid service and open a new account with Sprint so I can get a working device while retaining a service that provides unlimited data.

The person in retentions who I spoke with, who has been fantastic in going to bat for me so far, is as confused as I am with Sprint's policies and the actions that I've gone through with CS on the phone and in the B&M corp store. I have no doubt that the 30 minute call I had with her where we discussed possible solutions is what is going to keep me as a Sprint customer in the long run.

Good on ya Sprint, just fill the rest of your CS department with people who honestly care about your customers.

That we definitely agree on, I left AT&T which had data that was literally 10 times faster just so I could have unlimited. There's no 4g where I work or live but the 3g isn't horrible and my plan is still cheaper with insurance. Sprint waived my activation fee and gave me a 10% discount because I have an old AOL email account lol. I love Sprint but I left before because I went for weeks with no service at home due to tower issues.

I've tried the stock, LoSt and Zedomax kernels and the problem continues to happen. If you have any other suggestions I'm open to them, I'm just getting fed up. Thankfully Sprint is letting me out of my contract, so I'll likely just be getting a different device.
