[APP] Seismo - v0.12 20/09/2008

Hi,
Here is a small application which uses the accelerometer and draws a small graph. It uses the g-sensor managed DLL from Koushilk Dutta (and you'll need the .Net Compact Framework 3.5 to run this on your Diamond)

Edit: 20th sept. version 0.12 of my Seismosaur detector
zoom in/out with nav button (circle clockwise / counter clockwise)
close button
screen should not turn black while Seismo is running
now the scale is inverse tangent like
Have fun (though fun won't last for a long time with this )
PS: and I already know that this is silly and useless, and ugly...

nice tnx. downloading now.
(the best GODZILLA detector there is XD

Thanks in deed... I was just looking forward for this thing... Pencil is a cute user interface
Just a couple of question or feedback let's say:
-- The seismo in iphone was much more sensitive than ours... Even somebody's walking in the room was enough to disturb needle. Is it all about hardware? The response of accelerometer?
-- This lovely program is only deviating in "normal direction to screen" as far as i observed... I haven't seen a real seismograph, but is it always the case? Or should it react against the "resultant acceleration of three directions"
Thanks for the program...

Great APP, I've waited long for Seismograph for Diamond.
However it would be nice to:
1) change the pencil with the proffesional needle image?
2) make it more sensitive (or let us choose the sensitivity ),
3) prevent the screen from fading when the APP is running,
4) add some sound?,
5) add the possibilty to save the session,
6) maybe add the Richter scale meter somewhere underneath?
Heh, a long list, but I hope it will help to improve the APP

Haha... Love it!

I'm not sure about the sensitivity, maybe it's the scale i've used (a logarithmic one may be needed, as the iPhone version has)... I'll try some adjustments... but i'm not trying to compete with the iPhone version here nor the results can be compared. iPhone's Seismometer measures some "energy" and not the raw acceleration. Maybe they square it or they integrate it, i don't know...
You are also right: I'm only measuring "up and down" accelerations. It could also use the norm of the vector if you think that it makes more sense.

Here my ideas for processing of raw data coming out of port:
1- As you've suggested, a log scale may let you magnify the result. Actually it will not magnify but it will let the output be scaled on a narrower band (visually). it means you will have a bigger space to plot data's. So you can increase the output by some constant (multiply with 10 let's say), or even maybe take the cube of the output (taking square will cause problem because negative results will turn into positive then) So we can see even the very small disturbances. and since you use log scale, big oscillations will also not be problem, they will nicely fit on your log scale.
2- Secondly norm of the vector seems like a better idea. Because we're not looking for something scientific or something based on real scales, you can use a resultant vector. The users only want to see the movement of your pencil in any case of disturbance. So sqrt(x'2+y^2+z^2) will be a more useful raw data output just before multiplying with proportional constant and scaling on log paper.
One more time thanks for your effort....

Very very very cool.
thanks very much for your time and effort
Highly appreciated.

works flawesly no probs with sensitivity HR...try to put Dia od table and you will see some vibrations even without any "seismic activity: so maybe appreciate option to stabilise common distorsions caused by HW such a very small iregular deviations...but leave to measure also this small distorsions so to do some switch...but very very amazing app...
I hate iPhone and iPhonemania but its good inspirations for all WM community

Very nice app.
Some suggestions
-exit button
-You can also do this with sound (decibel meter?)
-scale option
-real needle image
Great work so far thanks

Thanks for your feedback and suggestions, I'll try to improve this draft - I did not spend a lot of time on this as you may have guessed
I'll try first to change the scaling, find or draw a "needle" picture and have an exit button.
Stay tuned...

I was finishing my seismo program last nigth but you got ahead
Aldo my program have more features yours have a lot better interface, this was my second WM program so i think its normal, could you share the sorce code so i see how you make the graph?
And i can share my formulas white you to, i was using this web site as base to all my formulas http://earthquake.usgs.gov/learning/topics/measure.php
Thx in advance

Hi Ikari,
I had seen the thread where you said that you may code something, but at this time my small Seismo was already on its way...
Of course I'll post my C# solution on this thread this evening/night (European time too) when i get back home and have 5 free minutes
Feel free to use it!

where I can take .net 3.5??

==> .NET Compact Framework 3.5 Redistributable

To Ikari - and all those interested - here is a link to the current zipped solution (VS 2008):
SeismoMeter.zip (696 KB)
The few interesting things are in SeismoMain.cs...

Video of the app here.

really cool app. kudos from me
several small questions - would it be possible to somehow save the data / the graphs?
and it'd be cool if the device didn't go to sleep after the wm-preset time...

Very nice one.. I wouldt be nice to save the graphs and for example put the phone on the table and If your girlfriend/wife took it for a few moments then put it back.. you can see that ... just an ideea

Nice app!
What to add a fullscreen mode ?

[App idea] Aetherphone - a musical theremin on your phone.

"Turn your phone into a robust musical instrument."
I am an artist and can do UI if a developer wants to tackle this. A theremin can be described here:
Here is a demo screenshot I made:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
in this demo picture it is showing the "R" reverb filter being scrubbed to 54% the text on screen quickly fades away once the affected button is released.
How to play:
The screen will be able to operate with the vertical axis as pitch (in herz) and the horizontal axis as volume (as %). Optionally these axis can be switched by the user in "settings". Also you can have a split screen mode for two independent instruments OR spit screen with pitch in one window and volume in another is so desired. If the latter sound will only come out when both fingers contact the phone.
Pitch range is by default 100 - 3000 hz but this can bet set to a different bracket in the settings dialog. on the top of the screen it will read the current pitch and closest note your finger is at example: 297 Hz (D)
Waveshape Selection Circle:
Toggles sine, triangle and square waveforms.
Filters:
You have three filter slots that you can customize with 15 different effects. Swap out filters in the settings mode.
• Tap a slot to toggle it on and off while in play.
• Touch and drag side to side on a slot to change the intensity of the effect. While you scrub a large number shows up in the middle of your screen to show you what its value is.
Loop:
Tap loop once and it inverts. While it is inverted it is recording.
Tap a second time and the loop is stored and a number comes up at the top of the screen 1-9.
Tap the numbers to toggle on and off loops. to clear a number drag the number to the settings gear at the bottom of the page. Loop auto snaps to the closest logical length of measure (guided by bpm and time sig settings)
BPM & time signatures can be set by scrubbing left and right. The text pulses gently to the beat and the time sig pulses to the appropriate scale.
Particle effects change under your finger depending on how long you have held a ante and how quickly your finger moves:
Tap a note/vol and a ripple happens like a drop of water.
Sustain a note and you will get many concentric rings fading from that spot.
Zip from one note to another and a line will appear to tell you were you came from. it will fade in one a couple measures.

where can i dl the app and use it ?

Read the post.
Whilst this looks way above my coding abilities, I'd love to see this app completed. Good job with the UI, it looks great!
Sent from my Optimus 2X using XDA Premium App

lol, I guess at least proves that there would be an interest in tackling such an app.
Meltus, I am guessing that its the filters that would be the real hard part? I have a hard time imagining the sine pitch to x vol to y would be super hard right? perhaps the visuals might be tricky too, I dont know.

hey man , great job. i think you have found a good developer. i know a man who is exploring music apps, their apps are much simpler than yours. LOL .To be exact, they are music downloader.

this is great! it appears to be a pretty straight forward app. tying tone and pitch to x and y axis inputs on the touch screen. id love to help do the underlying coding but the ui would be tough for me to code. never been much of a ui coder. just logic... perhaps create a github repository for the stub of this app and let us give it a shot.

ok, so I am new, what is a github?

GitHub is something like a SVN(Subversion repository).
It allows multiple people to work and collaborate on the same code.

HD Wallpaper Template

I started a new post because the other template wallpaper threads are not accurate. This template will not scale and has layers of both landscape and portrait home screen outlines. I also made a layer with the landscape icon grid for adjusting backgrounds to match icon placement.
I made this template through trial and error.
The template is in .psd format.
There are 6 layers.
- 1 Landscape homepage outline (Green)
- 2 Portrait homepage outline (Red)
- 3 Landscape Icon Grid (White)
- 4 Test border (Red) used to test borders.
- 5 Wallpaper Dead Space (Greenish, used to show dead space)
- 6 Background (Dark Grey)
To use in GIMP. After opening template, goto file, open as layer. make sure opened layer is between 4 & 5th layers. Align, turn off visibility to all layers but 5 & 6, then save as a png.
Upload to tab and use stock Gallery and stretch as far as possible.
Again, the green is dead space, it will not appear once loaded.

Here are a couple of wallpapers, not great wallpapers, but HD images to show the power of our screens.
Google Storage with More Images
I just removed the other images, they are too big, they can be found at the link above.

Great work, Honeycomb's useless wallpaper picker is my biggest complaint with it, this will be very helpful.

Cool
Excactly what I needed!

thanks a lot, lot lot, very good work
very useful !!!!

i was gonna use your template to make my own wallpaper, but I found the one you made with the record and it was pretty much what I was gonna make anyway, so I totally stole it! Seriously though, thanks a bunch! you are awesome.

Post an image or a link, and I'll make a wallpaper and post it. Has to be at least 1920x1080.
1920x1200 works better if you use portrait mode.
Glad to hear it's getting used.
Give me some thanks if you like it.
Much appreciated.

Id like to see this one if possible. It would go good with my boot animation,

Some of the ROMs have different borders, let me know.

i found on my Iconia very strange behavior
ROM HV 1.2 with Richard's Kernel 3.4
I just took one of your wallpapers (i tried as well others) and put on my home screen and directly after that i saw small pieces of those green corners on my tablet in every corner - but only on the last left or right screen - in landscape - in portrait was ok.
But after reboot - green pieces where gone and the wallpaper looks great.
Strange.

Hi, Scott,
I have tried to use your template here but I'm not having any luck getting this to do what I want, I have attached the image would you be so kind as taking a look at it and if possible fitting it to within your template. I would like it to be perfectly centered so that if in landscape or portrait it is perfectly in the middle, with a light blue background on the image.
Thanks for looking at this.

No Problem
Hope this works, I took some liberties.
The easiest way to get an image is to open it some sort of editor and make the dimensions 1918 x 1406.
My template was for the original ROM, I have since change several times and for whatever reason, each ROM is a little different. I believe the template I used was right, but if not let me know what the issues is, namely some of the green is showing up and I will see what i can do.
If you like, hit the 'Thanks' button.
Scott
Here Here & Here

Those are all awesome. I do have some green... In Landscape, I have some green on the bottom in the far right and left screen. In Portrait I have green on the bottom on all screens
I also notice that when I expand the crop picture the interior lines do not match up to the edge of the green, should they?
Thanks
Harold

dude! i don´t know how to make this works...
0 knowledge about design programs...
if you can make this pictures a nice wallpaper with your template i will be forever in your gratitude.

(sorry for my english)

Wallpapers
I redid the book Wallpapers and created the beach wallpapers.
The beach ones don't work well because the focal point is not centered and the entire purpose of the template is to not rescale an image and lose definition, I am not really interested in doing something that can be done in Paint. Take 20 mins and figure it out, or better yet, take 5 mins and Google the right resolution.

and this is the right resolution? 1920 x 1408??
http://www.umnet.com/pic/diy/screensaver/e99c4010-8a6a.jpg
thanks!!

Just load it then.
I thin the actual no scaling resolution is 1918x1406, but it won't matter fro that image because it's not HD.

Yes you are correct. The correct resolution of the wallpaper for the A500 is 1920x1408. Not sure where others are getting their information from, but the wallpapers that come stock with the A500 are ALL 1920x1408.

Damn kjy, wish I would have had that info long ago.
I got my dimensions by trial and error, using a magnifying glass to see exactly where the borders were, looks like i was off a pixel or two.
Thanks for the info and sorry nitudo for giving out bad info.

you rock! thanks for this..

Nice one..
Sorry but the first is mine

Good find PMoto.
https://youtu.be/5gFzzwbpKYA - this is the video from the website. Hopefully the battery will last longer with the e-paper screen. Let us know please when you get a chance.
A watch like this with a SIM and would be a good idea.

i see a headphone symbol, another watch that NEEDS a audio connection to function?
that thing is HUGE!
menu's look familiar, another U8 clone?
(if the u8 is the original at all)

Well, this battery should last 3 days...

Uwatch?
My friend, this is nothing to do with Uwatch.
This is a superb smart wacth and you cant find it in Uwatch .
Its a stand alone and you can use it with Bt connection
Mine make 2 days allways on, the E ink screen is amazing.
4 days with no Bt connection.

Here's the smartphone app:

KWatch looks interesting. I also tried the APP and it definitely needs an English version. I don't like the fact that you have to login/register to use the APP. Why is that? I just need it to sync with my phone and send info to the watch, not some database half way around the world.

EPD beautify gesture idea: thoughts?

I occasionally read a book or a longer text on the EPD of my YP2, usually with the YotaReader app. That works ok, but there's a small issue that annoys me: it's the jagged edges of the characters, which makes the appearance of the text less nice.
Yota uses a black & white only (2 color) mode of the EPD to provide maximum frames per second (8) without flashing, which allows for relatively smooth interaction with the EPD screen. The technique comes in handy when scrolling webpages, turning YotaReader pages without flickering, and many interactive screens, like navigating Apps in mirroring mode. By using dithering the 2 colors are used to simulate grey colors. This works great on pictures, but less well on text.
The EPD can also draw in 16 colors, which is used for the Yota panels screens, and e.g. the YotaSnap picture viewer. With 16 colors, it provides far nicer quality than the 2 color mode, at the expense of slower drawing, extra flashing and no interactive scrolling etc.
Here's an example of the difference in quality between 2 and 16 colors:
2 colors (with dithering):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
16 colors (possibly also with dithering, but less obvious):
(The 16 color photo is a bit blurry, both are actual photos of the screen taken with a cheap macro filter)
Text rendered in 16 colors looks much prettier. I'd like to be able to read a book like that!
I've been thinking for a while about a gesture (like a 3 or 4 finger tap) that would allow the current 2 color screen contents to be re-rendered at 16 colors. So imagine browsing a web page on the EPD, or reading a book and when you're done scrolling/turning a page to a location you actually want to read or look at for longer, you'd make the gesture and the screen would 'beautify' itself into 16 colors. You could not interact with it smoothly anymore at that point, but reading or showing pictures etc would be nicer. Maybe it would be possible to flash the screen and return to 2 color mode when starting to scroll again etc.
Not sure how to go about this, but using xposed it would be possible to hook into the JNI calls that ultimately dither and draw stuff onto the back screen, or maybe at a higher level like the backscreen manager.
There are alternatives, like adapting FBReader for the EPD, with optional 16 color mode, but the gesture solution could in theory apply to anything on the screen, not just a reader app.
Anyone interested to help dig into this?

I like this idea, but I don't have the time to work on this.
What you are looking for, though, is changing the waveform from one to another: http://mwiki.yotaphone.com/wiki/Waveforms
The class EinkUtils inside the SDK has a lot of interesting methods which are responsible for updating the screen. Maybe using xposed one could switch the waveform on the fly when one of those methods are called, or even do a manual refresh with the desired waveform.

Ok! Thanks for the pointer. (I know about waveforms and update modes, but thought it was a bit too technical for a post to gauge interest in such a feature in the YotaPhone General forum.)
My time is limited too, I'll see if I can manage some experiments.

I wonder if the use of xposed is even necessary? Maybe it would be possible to create some service which would listen for some event, maybe volume up button or something, and that would just refresh the whole screen using the most detailed waveform. Not sure if this is possible, as at least the partial refresh functions wanted a reference to a specific view which is to be updated.. I don't have the API/SDK at hand right now, but one would think that there is some static function for updating the entire screen.

the backscreen framebuffer always contains a 16grey bitmap, so I fooled around with the epd sysfs interface (/sys/kernel/epd) to re-render the screen with different parameters, but no definite success so far. I can flash the screen that way and make it redraw, but not with 16 cols. For activation I was going to snoop how e.g. three finger tap is handled (configurable for sleeping) probably in windowmanager class. (not near a pc right now either).

Using the EPD kernel interface you can make the screen update like this, but it doesn't seem to actually change the waveform/number of colors.

[email protected]:/ # echo 51 > /sys/kernel/epd/update_mode
[email protected]:/ # echo 1 > /sys/kernel/epd/updateImage
The update modes:
UPD_INIT 50
UPD_FULL 51
UPD_FULL_AREA 52
UPD_PART 53
UPD_PART_AREA 54
The waveforms:
WF_MODE_INIT 0
WF_MODE_DU 1
WF_MODE_GC16 2
WF_MODE_GL16 3
WF_MODE_GLR16 4
WF_MODE_GLD16 5
WF_MODE_A2 6
WF_MODE_DU4 7

So what it does in practice is it draws each view using its own waveform, which makes sense. According to wiki the default waveform for a view is A2, which is black and white.
There is a method called EinkUtils.setViewWaveform(anyView, waveform) which can be used to set the waveform for any given view, and that is what needs to be overridden before calling refresh. That sounds like a job for xposed. Maybe the constant of WAVEFORM_A2 could be momentarily switched to WAVEFORM_GC_FULL and back or something? Then the individual views could remain untouched.

how do i do this//access the kernel? And how can i set the waveform for all views to A2? My YP2 is rooted. regards
