[idea] seismograph application

Today I have seen a seismographs application in iphone... A needle was continously writing the output coming from the acclerometer like those richter measuring seismographs.
And it was quite sensitive. Even if somebody walk in the room, you can see the changes in the seismographs. I really wanted to be able to write some code for wm but i can't... So maybe one of our you guys can be inspired by this and can write something similiar for this... I really like to play with these g-sensor programs...

I could not grab enough attention for the european users... So I try my chance one more time in the time zone where american users are mostly active...
A seismograph application... I don't think that it's that difficult... the code does even not to suppress the disturbance... Because actually it should be measuring the disturbance continuously...
I've also heard that it is a free app. for iphone... I don't know maybe the code of that program is somewhere available...
Cheers,

I could try making that app but could you post the link for the iphone version plz? out puting the sensors are kite easy for me atm but i don't imagine the relation bethen ms^2 and Mercalli scale. so yes the needle will will shake but i don't know what to put in the tag's
ps im European

Ikari... You are my favorite coder... After your accelerometer, responding to this has proven it one more time...
Ok so here some youtube links to see how it looks like...
http://www.youtube.com/watch?v=Y93QrIYsM6o
or
http://www.youtube.com/watch?v=OK1GNbNZcmE
Basically you don't need to think about the unit conversion or any other... I mean as you see on iphone, it's something ver simple... Not scientific... No units... Just a scale on the "rolling paper"... Let's say the maximum disturbance is the limit of the paper and it's 3 times of gravity... A simliar UI would be really nice... Maybe you can also think of a logarithmic scale (which is the case for richter scale) then you can even show 6 G on the paper... it will not take so much place for the increasing gravity (i don't know what is the maximum output you can measure with the sensor inside)
It would be really nice to see such a thing...

P.S.
You can also find some explanation and screenshots of the program from the following link:
http://translate.google.com/translate?client=tmpg&hl=en&u=http://coneri.se/iphone/&langpair=sv|en
(translated to english)
If you have an apple account, you can also download the iphone version for free!!

that's a cool idea...+1 from me

me too...

+1
it's really a good and funny idea

DOn't make the mistake of making it simple, it will only be a laughing matter for the fanboys at work if you know what I mean. My point is, if you're going to copy, why not improve the idea right?
Btw, great job on the accelerometer Ikari, you're the man!

FpseCE and the HD2...

i have made the decision to uninstall FpseCE
i love playing my old PSX games on my HD2, after reading the readme and following its instructions to the letter, it worked first time
the app i have no gripe with, yes it could be better but the developers have lives away from their PC's and cant dedicate all their time to satisfying my gaming fix.
On the HD2 with its MAHOOOSIVE screen, portable gaming has been a wonderful experience... Granturismo2, resi evil 2 and 3, tekken etc etc
*But*
1/ i am getting nothing done.
2/ the house is falling apart.
3/ the car has been sat on the drive for six months purely because it has a flat tyre.
4/ i keep missing my stops on buses and trains.
5/ i've fallen behind at work.
6/ the dog keeps coming to me with its bowl in its mouth like it wants something...id give it more attention if i could just beat this level!
7/ more importantly i'm single again...so will have to take up the chore of finding another female of our species in which to grow my brood.
on the plus side...
1/ i finally got 100% completion in GT2
erm, thats about it really...
so FpseCE is going, i must find something to feed my gaming fix in the mean time (like nicorette patches for smokers)
any ideas?

Wow, I've never finished GT2 on the PSX.. you got me interested!

its not easy! the licenses and endurance events are impossible without an external controller!
at least, they were for me and my clumsy hands lol
id just got back into resi-evil 2 im thinking i should at least finish that before uninstalling...

Hi there, are u using the supporters version? to enable multi-touch on our beloved HD2s? im considering getting the supporters version as well. though i wont be playing anything too time consuming. maybe metal slug or some fighting games. lol. does the multi-touch work well? do the controls work well? i know on the normal version its really hard to activate the buttons n all. lol

if you have an hd2 it is totally worth donating. its not much to ask for the years of hard work put into this emulator and the features you will have with the supporter version are a must have on HD2.

Yep, I love FpseCE. It's awesome, I basically got the HD2 for it. I find the controls ok, but I think I would struggle with fast paced games.
For Gran Truismo 2, the OP is right, getting gold in all the liscenses with the onscreen buttons would be impossible, but they are suitable for most races.
I play a lot of FF7, 8 and 9 as well, and perfect timing for the controls are not a big deal. This is where it comes into it's own.
I picked up the supporter version straight away, 5eur is nothing for what you are getting. I found a few games dont work, Metal Gear Solid is one, which is a pain but I think the developer is working on getting it up. Theme hospital is another that doesn't work that great.
On a side note, the developer seems to favour the HD2s, a lot of his time seems to be specifically developing for our device as it is so awesome and popular.

Is there a thread dedicated to FpseCE? I am a bit special when it comes to things like this and would like a littles step by step guide on whats required, ive got as far as installing it .

It's not too bad to do mate. Any help required, the FPSECE forums will help you out. There is a specific section for the HD2 and it's one of the most active sections of the website. The community is pretty helpful in general.

there is a dedicated thread for HD2 on there forum check it out no link cause im on me phone on the bus, but therw is a guy on that yhread he is awesome answers for any question.

cheers guys, will check it out, am i right in thinking the general concept is similar to mounting an ISO image using something like daemon tools on a PC?

Yeah kindof, except it runs an emulator to actually read the data. The developer provides another tool called pocket ISO I think. This compresses the ISO's obtained from PSX disks to a smaller size and actually increases performance. Not sure of the math behind it, maybe stores the data in a way that FpseCE can access it better. Either way, smaller ISO files and more FPS. I am by no means an expert but if you get stuck, you could fire me a quick PM and I'll see what I can do.
Essentially you install the free version, install the supporter version, download the "HD2 pack" available from the forum under the HD2 section of the forum (sorry, no link, the site is banned at my work)
Pop the ISOs on you're memory card, and fire it up. Easy as that really, that's all I had to do.

thanks a lot, seems pretty much how i thought, i'll give it a go later when im home from work.

Need general help. Please just read.

Hey all the good people at XDA. I have an idea and the potential parts to make this work. Think of it like a Google Glass ( another glass concept ) but for the combat Infantrymen. We wear eye protection already and put some crazy stuff on our helmets. We get shot at and we shoot back.
This is where I and trying to help.
The concept:
Being able to know and many rounds you have fired.
able to tell distance, direction and elevation the shots originating from.
Able to tell what round was fired.
The hardware:
Will be tested on Oakley M frames. I am drafting up at the moment.
Small screen on either eye but supposed to be your non firing eye.
there will be small mics around the helmet. This is what will give direction.
There will be a small shock sensor and mic to give an accurate round count.
What I want to try to use:
I have an electronic viewfinder screen from an old digital camera. that's what I will look up to. I have the orignal PCB that I know has the TI DPS. I think it has whatever display chip on the board as well. Basically I tore a kodak easyshare z710. I don't know what firmware type is it. Maybe Linux but I don't know.
Can I get some help on this. Is a little near and dear lol.

I don't actually understand what kind of help you need. Do you need hardware or software help? And if you plan on an endeavor such as this how do you plan to obtain funding?
Please give a thanks if you think this post helped you!

can you elaborate it a bit more,seriously I could not make out where you need help

I'm sorry guys, I think my sleep meds started kicking in and I just zone out.
Basically I want to make a small projector with the hardware provided to project an image onto the lens of my Oakley eye pro. The mobo in the camera has some sort of OS. I don't know what it is (I would think Unix of some sort).
There is more to it, but the hardest things is getting the projector work right and have control from a smartphone.

So what do you need from us? I'm confused...
Please give a thanks if you think this post helped you!
Sent from my Nexus 4 using XDA Premium 4 Mobile App .

It sounds like the basic concept is there. I'm guessing you are looking for technical help to make this a practical reality.
So far I see that you have most of the sensors planned out:
-shock sensor
-mics
And the output:
-LCD from the camera
But it seems to me you need a microcontroller somewhere in there. You could use an Atmega (the kind Arduino boards use) or Microchip (probably 18f series) or AVR. I'm sure there are others. Depending on your level experience you may decide to go with Arduino (which are a little more expensive (usually $15+) then the others but includes it's own programmer (assuming you get one that has the USB on the board) and are easy to program (Arduino IDE has lots of code examples)) or you can go for a more low level one like a Microchip 18f4550 ($5) for example and program in C (I think this costs) or assembly (free) but you'll need to understand registers and some of the lower level aspects to microcontrollers (however there are free very in depth datasheets that will give you all the information (you'll just need a few months to digest it).
Those are just some ideas, this projects sounds quite awesome though. It may take you a 6 month to year to do though.

Building your own android "head unit"

Hi,
I am sorry if this is the wrong forum, I don't know enough to put it else where. I have a GMC full sized van. My DIN opening is actually larger than 7", I could fit an 8" screen in there if I wanted. I also have other options and tons of room. I could cut the dash, go as big as 15, or even 19". I could have a console where a large screen lifts up with some servo or mechanical assembly. Or just simply a flip.
I bought a Hui Fie (sp?) head unit that matches the van. I like it, the colors match perfect, it's the higher res, with a quad core. However there are few things I'd like to improve. I could almost lose the buttons and relocate key ones, like the "home", "return", "navi" etc for a larger screen. Also, I find the buttons feel rather cheap compared to even the GM ones. And the GM ones are nothing high end, but they feel right.
Is it feasible to build a carputer and run android in it? SW controls possible? Are the keys I mention above possible? Canbus? Or would there be another route available by using the head unit I have and attaching to it to a larger screen? One thing I wish these units had was hdmi in and out, and an RJ45 connector for hardwiring a network.
I have a lot of projects on the go, money I should be spending elsewhere, and time that just doesn't... seem to leave me with the right energy and mindset, but I'd like to know if these things are possible. Of course with money and time, but for an average or a bit over average determined person, can they set all this up hardware wise? Is there other directions to find these means? I could literally do anything, it's just time and resources of learning to code new languages and source parts, etc. that limit me. If we were all rich and retired, many of us could do amazing things.
For me, it's a distraction, a hobby and a way to improve my work life. As long as I get the project done. That's the other downfall, you start on a path of perpetual upgrades that never end. But it's enjoyable.

Some head units (the NU3001 for example) are nothing more than an android box attached to a double din screen and buttons. If you can find a monitor that will fit you can pretty much plug in the android box anywhere.

Hi,
Well, I kind of figured that much. I guess you're the only person I've communicated with that confirmed it. However, how would you manage hooking up a larger LCD? You'll most likely have a ribbon cable to connect and you will be limited to the same resolution right? Some of my ideas envision the box much further from the LCD screen. So even if the ribbon cable and drivers work with the larger LCD, it's a physical problem.
The buttons, I don't think they'd be too difficult. You could either solder a tacky solution with wires to extend the location, or you could use SW controls to a button layout with the same resistance values. Seems simple enough. I'd like to know if a car computer is possible in any highly simple way. I can't deal too much with software and drivers right now, too involved for my head with all the other things. But it would be nice to drop in add ons, have an rj45 connector, hdmi in and out.
Maybe my plans are too excessive. Actually, I know they are as of Friday, some priorities have changed and need to reduce things for the time being. This is just an exercise for thought and a potential path in the future.
I do like that radio. I actually wished I bought it after using mine for a little while. Same specs I believe, but the layout actually suited my desires better. Knobs are good, for the size of mine, I'd rather either have one larger, or none. The home and return are necessities to me now.

With limited time available, I think the answer is no.
Maybe within 1-2 years, with more "community experience" and threads etc., it may be more feasible for people with limited time.
I think the closest you can get right now is to install an Android tablet. This won't, in and of itself, provide hardware buttons, nor other things you desire.
All you want is technically possible of course (with lots of time/work), and I'm sure several home-built Android HU projects that go beyond installing a tablet will arise over the next few years.
For anyone who disagrees, note that OP does not have time to "mess around". If you still disagree, point me to a project thread or blog etc. where somebody has already done all that OP asks about and which won't require too much time to duplicate. Lets say,... 16 hours maximum.

Hello,
I want to use this guide for my head unit. But it says YT9216CJ, I have included pictures.
Also how do you connect this to a PC/laptop?

The easiest way is to buy a 12v 5A power adapter. Something like this. Then connect the RED (acc) and the YELLOW (B) cable to + (plus) and the black (ground) cable to - (minus).

That's good idea. I have many 12 volts adapters that I can use and strip them. I know that's unsafe and could potentially fry the unit.
I'm assuming a type a to type a cable is needed to connect it to a computer?

You will not fry the unit if you use at least 12V and max 14V adapter with a minimum amperage of 5A.
When you connect the cables, just put some electrical tape around the connections so they don't touch each other.
Yes you'll need a USB-A cable of maximum 90 cm long.
The next step would be to read the guides on how to install drivers in order to access the unit.

I would advise against using this mod on your unit as it does not support "HIFI" models. I am currently working on an Android 8 super mod and that includes everything. Stay tuned.

The new guide for Android 8 units is now available. It covers all Android 10 and 11 fakes.

Can my unit follow this guide or should I follow another One?

The proper root for this unit requires modified firmware. You can of course try without it but chances are you'll either brick your unit or in "best" case get unstable root.

Just gotta say I urgently wave anyone off of this project as it is.
Most importantly this line of tablets sucks. The screen sucks, the specs suck, the performance sucks, it's max 2g crap that'll still suck after it's hacked, the screen glare is laughable/day-unusable, it crashes, stops responding to physical buttons randomly, and it has no amp which will throw unsuspecting people. The audio it does provide is a total diarrhea blast through a cheap rca canbus adapter with ground interference for miles so again, you better have a rated amp and isolater for your speakers and know audio wiring. Also hey the software is clearly disingenuous chinese spycrap that would probably try to kindnap your child if it could, to the point that I don't know if I'd even trust root hunting to find all the lies.
Past that I can't endorse this tutorial either I'm afraid. Look at the failure/success ratio in this thread already and add mine to the failure pile.
Modders are going to get into this and dl a folder sequence that looks step by step for each but then opens up into different subinstructions requiring knowledge bases you didn't know you needed until you're in it. You're gonna be messing with device manager and secure boot modes in windows and custom power wiring outside the car just to get going. To deal with that you're going to go down more forum nightmares mid way, stuff that should all be on a unified 1,2,3,4 instruction set in the main post imo. I'm capable and I'd call this written procedure luring unsuspecting people into bad times.
I had to bail on this project some weeks ago after that "boot into secure mode in windows to install temporary unsigned USB drivers (which can revert and fail while you're working on the project with so much as a windows update) just to get it to communicate" process. Then of course it never did communicate, step by step trying across 3 devices in specifiied acc wiring positions and every other attempt under the sun. This is of course after you've and soldered up this failure of a unit to a power source to hack it outside the car which is ridiculous to need to do in itself, and a dozen more things most people wouldn't sign up for if it were made a bit more clear.
I'd be willing factory reboot and get that guy from the android 8 thread the clean yt9216bj image except I don't want to waste day 4 screwing with the non working ass-up usb/windows head unit software.
The product itself is obviously not worth it and...rant but yeah this tutorial suffers from the super common XDA problem where the author is super tech skilled!...but just too in their own head to relate 1:1 what regular people need to know as if visitors were working along side them all year. I respect all the work that went in but imo this as presented seems to be tanking people's efforts and stress them out. It'd be more worth it to risk the brick if this were a hack that you shove in the usb and it goes. It's very not that.
At the time of writing I suggest saving yourself xda therapy costs, spend on a cruthfield screen that actually works, is nice, you can see in the daytime, you can mod into an enclosure yourself, and will probably have a way easier hack with much better function before and very much after a hack. I'm probably going to shove an m80 into this aptly named BJ unit and explode it like the chinese firework trash it is.

The audio it does provide is a total diarrhea blast through a cheap rca canbus adapter with ground interference for miles so again, you better have a rated amp and isolater for your speakers and know audio wiring. Also hey the software is clearly disingenuous chinese spycrap that would probably try to kindnap your child if it could, to the point that I don't know if I'd even trust root hunting to find all the lies.
Past that I can't endorse this tutorial either I'm afraid. Look at the failure/success ratio in this thread already and add mine to the failure pile.
Modders are going to get into this and dl a folder sequence that looks step by step for each but then opens up into different subinstructions requiring knowledge bases you didn't know you needed until you're in it. You're gonna be messing with device manager and secure boot modes in windows and custom power wiring outside the car just to get going. To deal with that you're going to go down more forum nightmares mid way, stuff that should all be on a unified 1,2,3,4 instruction set in the main post imo. I'm capable and I'd call this written procedure luring unsuspecting people into bad times.
I had to bail on this project some weeks ago after that "boot into secure mode in windows to install temporary unsigned USB drivers (which can revert and fail while you're working on the project with so much as a windows update) just to get it to communicate" process. Then of course it never did communicate, step by step trying across 3 devices in specifiied acc wiring positions and every other attempt under the sun. This is of course after you've and soldered up this failure of a unit to a power source to hack it outside the car which is ridiculous to need to do in itself, and a dozen more things most people wouldn't sign up for if it were made a bit more clear.
I'd be willing factory reboot and get that guy from the android 8 thread the clean yt9216bj image except I don't want to waste day 4 screwing with the non working ass-up usb/windows head unit software.
The product itself is obviously not worth it and...rant but yeah this tutorial suffers from the super common XDA problem where the author is super tech skilled!...but just too in their own head to relate 1:1 what regular people need to know as if visitors were working along side them all year. I respect all the work that went in but imo this as presented seems to be tanking people's efforts and stress them out. It'd be more worth it to risk the brick if this were a hack that you shove in the usb and it goes. It's very not that.
At the time of writing I suggest saving yourself xda therapy costs, spend on a cruthfield screen that actually works, is nice, you can see in the daytime, you can mod into an enclosure yourself, and will probably have a way easier hack with much better function before and very much after a hack. I'm probably going to shove an m80 into this aptly named BJ unit and explode it like the chinese firework trash it is.

First of all, really sorry to hear you had such an unfortunate experience.
Now let me add a few points to your feedback.
1. You need an understanding of both PC computers and Android devices to attempt this. Would you try to repair your car with zero knowledge or experience?
It's also a good practice to look through all the steps and tutorials before deciding whether this is something you wish to attempt.
2. The reason I create these guides is to give the users one-stop software solution in one thread. I couldn't find similar guides here.
3. Software packages are cleaned from the bugs and issues you would normally experience in these units and overall improvements are considerable. If you check the video in my signature, tell me - does this seem like a slow unit? And it's only 1Gb RAM one.
4. These software packages perform even better with appropriate hardware mods. Especially the sound quality. You can check out this website for more info.
5. Users who experience issues post here. But this package alone has over 300 downloads. This indicates high success ratio.
I also help individual users by PM.
Thanks again for your feedback

Well, let's go point for point a little bit.
1.) Yeah but when was that in question unless you're mayyybe trying to sass a bit? My personal experience is plenty for this, enough to multimeter my harness pin by pin, design a custom wire harness with 3d printed parts, run debugs with my obd, reconnect lane cams, write my own android apps if I feel like and on and on. My point is to warn to readers that these instructions are pretty deceptive about how involved it is skillwise and just needs a simplification redo. My problems might have been isolated hardware failure, I still don't know after tons of debugging.
2.) Cool, noble, etc etc, you're very nice for doing it. I just want people here to write clearer I guess. Sorry I landed on your project to express it. Years of XDA and it's so much life lost to information gaps / gotcha tutorials. That gets pointed out and it's usually ego mania. Take some crit, XDA posters could really learn what a tutorial format that communicates to most everyone should look like instead of assuming their skill at that is also great thus providing good intented tuts that cause uh....pain.
3.) It'd be fun to test myself but it doesn't work. Looks functional sure. Speedy compared to current gen anything after esp hacks? Nawwww. If you're cool with it chugging after one or two background process I get it. Waze eats enough. While it won't be everyone, if you use a screen with more expectation I again advise against this hardware.
4.) Again for people considering this, how much extra hardware and wiring do you want to buy and staple to a piece of crap and shove behind the head unit to make it almost not suck? How many 3rd party peripherals do you want back there doing one job? Are the manhours you'll spend trying to reign this unpolishable turd in monetarily marginally close to worth it? Appreciative to the hack effort if you're stuck with this screen. If you haven't bought it friggen doooon't.
5.) I argue since silence is not success confirmation it could just as easily indicate people downloading it, the process failing, them not wanting to continue with a newly recognized tragedy of a device, and possibly just dying of dysentary right there while reading the instructions which are in 8 different folders

1. Why not explain what were the issues you encountered?
2. It has taken me a couple of years to learn how to properly work with these units. I tried my best to write as easy to follow guide as I can. I'm grateful for feedback as it helps me improve these guides. They are continously revised. I'm not paid to do this and it is a fairly time consuming undertaking.
3. Current gen Androids are an unfair competition to hacked and re-hacked Android 6 or 8. On the other hand, you can't do much with anything above API 27. Forget about rooting, Viper and TWRP. Also be prepared to pay hundreds of dollars for these units. People who buy Mediatek head units, normally can't spend such money but still deserve great results. This is why I share these mods packages. And it's completely free. All it takes is time and patience.
4. People here and on similar forums are many times interested in making improvements without spending loads of cash and might already have some basic equipment and skills. I haven't posted any hardware mods guides yet but I'm going to.
There are no 3rd party peripherals required. Most of the spare parts can be found in old computers. We at Extrememod.co.uk use premium spare parts as we sell these units fully modified (for charity, no profits) but it's not a requirement.
5. All I can do is to encourage users to post here so I can help if needed.
Cheers

I spent a few days as I said fighting it after it all fell down during the USB unsigned driver portion of the project. Across 3 pcs, driver reinstalls, pin verifications, living in device manager, 12 tech forums tabs open and everything else under the sun the software just refuses to communicate with the screen in any way.
I don't remember everything, I'll get you verbose logs if I ever touch this project again but don't hold your breath. I'm surely bitter over wasted time but in general the nature of in car entertainment cheapouts that need these hacks to even start limping have caused me to reevaluate life itself and what not to waste it on so I'm just pulling the trigger on a Model 3 finally. Screen problem solved for me I guess
My suggestion for readers considering buying remains to run far away if you're not already stuck with the hardware. But if you are and you have infinite patience trying to buff it up then I guess keep harassing poor iceblue here until your hack works and weeew I do wish you all luck!

If you are unable to restore your unit, I can have a look at it if you can post me the motherboard. I live in UK. If that's not an option, why not donate it rather than throwing it in the bin? I can arrange pickup if it's within reasonable postage fees.

I'd donate but the math will never work out. It's installed in the honda which I'm selling already, so it'd take pulling it out which us my time+shipping hassle from the states. If I pull it out it's easily worth the $250 cost of the unit in therapy to see it *explode* and I'm not joking so I doubt you're gonna front that too. :v I mean also I don't really want anything about these boards perpetuated. If the next buyer doesn't want it in there it's getting smashed. These kinds of posts I make again to save people time on caaaancerous base products.

I understand. I actually care about people succeeding with these mods. You can clearly see how much time I'm putting into these guides and helping people with any issues that come up.
I even offer repairing boards, for free. Donation is a last resort if someone wants to throw their head unit into the bin.
Any modification, as it's essentially a hack - means you're taking a risk. But with proper backup, the risk of ruining your head unit is minimal, as you can always restore it back to what it was.
Again, I'm sorry it didn't work out for you but the issue isn't with the software nor the guides as the success rates are overwhelmingly high, judging from the feedback I receive here and on my website.
