I recently purchased a DSLR camera to take pictures of my stuffed animals. They are alive but they only come to life when I'm out of the room. I love them so much and I just want some kind of proof that they are alive so I know that I'm not throwing my heart into nothingness.
I purchased an older model DSRL that wasn't equipped with any WiFi abilities like some of the new models. I wanted to be able to view and control my camera through my tablet screen. I found out that I could use a USB OTG cable to plug my DSLR right into my tablet. Then all I needed was an app and I was up and running.
Here are the things that you will need to make this work.
1. OTG Cable
An OTG cable is an adapter that will enable you to plug a full sized USB cord directly into your Android device.
Micro USB OTG Host Adaptor
2. Android Device
You can use almost any Android device as long as you find an app that is compatible with it. I used my Sony Xperia Z3 Tablet and it worked just fine.
3. USB Cable
You probably already have one of these. You'll need a usb cable that can connect to your DSLR camera. This is the one I used to connect to my Canon camera.
USB Cable
4. (optional) DSLR phone mount
If you're using a phone, you can buy a mount that will allow you to connect your phone right to your camera. The mount in this link is meant to hold your camera and use it as a flash for your DSLR. For this project we will repurpose this device and install in backwards so your phone screen in facing you.

5. DSLR Remote App
I tried out a bunch of different apps but only found one that worked. It also happened to be one of the only ones that was also free. SCORE! I recommend trying Helicon Remote. It worked great for my Canon and was able to do everything I wanted it to do.
Download Helicon Remote
If this app doesn't work for you, then just search around until you find something that does. The term you'll be searching for is "DSLR Controller"
Now that you have everything you need, start by connecting your USB OTG cable to your android device. Then connect that to your DSLR camera using the standard USB cable and launch your DSRL Controller app. If everything works, you should be able to see the live feed from your camera and be able to control it as well!
Here are all the features that I was able to use once I was all setup.
Key features:
- Automated focus bracketing (focus bracketing, exposure bracketing and time lapse shooting can be combined in any way possible)
- Focus stacking result preview
- Extra long exposures - up to 32 min (all Canon cameras, Nikon D750 / Df / D600 / D610 / D800 / D810 / D4 / D4s / D7100 / D7200 / D5200 / D5300 / D5500)
- Advanced exposure bracketing
- Image review
- Geotagging (on devices with GPS receiver)
- Full screen Live View
- Focus areas highlighting
- Live View noise averaging
- Time lapse shooting
- Video recording
- Burst (continuous) shooting
- Hyper focal distance and DOF calculator
- Live histogram (gray/RGB)
By using my tablet as a controller for my DSLR, I was able to monitor my stuffed friends without being seen. I have not seen any movement out of them yet but I wont give up!

I absolutely love these apps. I have a large power bank strapped to my tripod for when I'm shooting video and I use my old Galaxy S5 as a monitor for my camera. Generally I use it for focus peaking as Nikon does not natively support it. I believe it's a Sony trademark.

Hello and thank you for sharing this information. I am using a Sony SLT A65 and I would like to know if this method is going to work with my camera. I should mention that my A65 does not support tethering. Thank you. [email protected]

Connect Universal directly to 80GB Mobile Hard Drive?

Is there any way to connect the Universal Directly to a mobile hard drive?.
to be more precise, to this one:
http://www.lacie.com/products/product.htm?pid=10669
Not Directly NO. The Universal does not have the USB Host hardware required to attach this kind of thing.
Take a look at this...

Universal has WIFI so youd be better off just mapping a network drive or something rather than using bluetooth which is very slow.

That would be a PC Its certainly possible that somebody could make a card for the SDIO slot that would support USB Hosting but I am not aware of one.
Better wait for cheaper 4 gigabytes sd cards
Hi jimcl,
You have the same idea as me! I was thinking of hooking up my external 60GB HDD to my Exec using just a normal camera USB cable. As you have thought, it didn't work. Wouldn't it be great if things just works the way we wanna them to be?
I assume that if it works, the battery on your Exec will dry up very quickly as the HDD draws its power from it.
Anyway, if you find anything that allows you to do that, please post it out here and share it with everyone!
Cheers!
Regards,
Johnnie
Wifi would be much better, and is already available, but they are not designed for mobile use, mains supply required.
SDIO to USB is, I think is in the pipeline, but prehaps a better solution would be SDIO to Wired Ethernet, more likely to find this for PDA's with no Wifi, and USB/Ethernet hard drives are available now. Although ethernet drives still require mains supply but USB ones would suck power to quick from the host
I think we will see host controllers as standard in future PDAs.
I know the 5Gb is not particulary good on the Toshiba device, but I doubt it will be long before the capacity increases.
I must admit, SD/MMC cards are a better way to go and I think 8gb is in the pipeline now and prices will drop over time.
of course I'll share the solution... in case I find it!
I more or less agree with all your comments... but sometimes we just want to work with the things we have, ... I already have a mobile hard drive. That's all.
Apart from 4GB SD cards - and future 8GB - maybe we could find a solution in the WIFI way, but anyways 8GB SD card sounds great - maybe not its price..
If your looking for a solution for home or car try the asus WL-HDD wireless access point / hard drive
I picked one up off ebay for 50ukp with a 60 gig drive in it,
Also lets you copy stuff from other usb devices to the hard drive (without a pc) or share other usb devices over the wireless (with new firmware from asus).
http://reviews.cnet.com/Asus_WL_HDD_2_5/4505-3382_7-31080278-2.html?tag=nav
Power wise it needs 5v @ 2 amps
Being linux based there is also some hacked firmware that will let you use other usb devices or turn it into a webserver and other things..
http://wl500g.info/
currently selling in the uk without drive for around 36ukp (scan)
RE
Yes, you can connect the Universal to the hard disk directly WITHOUT going through a router/access point using Wi-Drive, here:-
http://www.edslab.com/products.htm
Spoken to the developer 2 days back and was told that it'll be ready this coming August. It'll be released with a 30GB hard disk as this will be more affordable to the public. If you need higher capacity hard disk you'll need to install it yourself.

Is this the successor to the Universal ?

http://www.europe.htc.com/products/htcadvantage.html
this article suggests it is:
http://www.reghardware.co.uk/2007/02/13/htc_rolls_out_h1_07_lineup/
http://www.seehtc.com/
Looks promising.
Note the VGA Out?

i need this!
Well it's a cool device, but I sure hope it's not the successor to the Universal.
Stick on Universal for me, that is huge phone if in my palm. Anyway if someone give it to me as gift, I won't disappoint him/her, I'll use it...
From what I read, this has a detachable keyboard, thus I can't consider as a Universal successor.

To fast to talk? But if I read more and see the pict that uploaded that compare Athena to Universal... I think i'm start to fall in love with athena???
its really great device but for me I am still thinking I have same usability with my old universal. Sure, I would like 8Gb hdd and 5'' LCD but except of this I find nothing more usefull in everyday life.
I am fully aware of usb-host and ext. VGA -these are really great extensions but I am asking myself how many time I use VGA out except of those first time shows-off to my friends. Same for USB - How many time I attach external harddrive.
My point is - I would consider spending around 1K$ for a device with similar specs like my old uni.
But of course If I dindt have Uni I would definitely consider buying it.
And I would buy it right now if it would have 800x480 display or something with better resolution - this is the most important feature for me.
just my 2c
best,
Whoa...awesome . I'd have thought VGA res would look a tad pixelated on a 5" display, considering that all other VGA's are 3.7". But this one manages to pull it off...Is it an 18-bit (262K color) TFT, or the regular 16-bit?

Shift vs. Archos 9 for school use. Advice Please!

Hey guys, I'm a medical school student, and I'm looking for a device to pretty much just run MS OneNote. I'd like a decent battery life running Windows 7, and good performance running OneNote and reponding to the occasional email. I currently have a very powerful Sony Vaio Z as my main laptop, but I really wish I had a touch screen to take advantage of OneNote. I don't necessarily need a keyboard since I don't do much notetaking/typing in class, moreso I try to listen and annotate the professor's pre-printed slides using OneNote to highlight, draw, and write an additional sentence here or there.
So Archos 9 or HTC Shift? Tell me what you think about speed, screen, portability, the hardware keyboard, ect. (P.S I'm not looking at traditional convertible tablets b/c of the fact that I have a Sony Vaio Z that I'm happy with and would trade for a lower performing, bulkier, traditional tablet... I just want something light and touchscreen for OneNote only).
For those of you unfamiliar with the Archos 9:

Shift for OneNote
I bought my Shift for nearly the exact same reason...as a OneNote client w/ handwriting instead of a full blown tablet. Once i found a comfortable position to write without my palm touching the screen, I haven't looked back. My only complaint is the battery. There's nice looking portable external battery that I haven't broken down and gotten yet...just google htc shift external battery. I put a 60GB SSD in and I can get about two hours on the Win7 side. Keyboard is decent enough for me to do other typing on too, but it is no replacement for a full size kb. I also like having the WinMo side in the event the battery is getting critical. I can shut down Win7 and then use the OneNote for Windows Mobile app and sync up later.

Why i purchased p3110.

took me:
5 minutes to root.
5 minutes to install CM10.
3 hours to mount it to the dashboard cause i had to cut a lot of holes in my car
But the project isn't over yet. I still need to fine tune the position of the tablet to it's sits against the frame.
Make a USB(OTG) y-cable so i can charge while mounting external storage.
Fine some more awesome applications for the car
But now to some question
Will it even be possible to charge while using USB host through a y-cable without hacking the kernel?
Sweeeeeet! Keep us posted, also would love to know how your best connectivity is. WiFi, 3 g, Bluetooth, etc.
Thank you!
I cant answer your question... but try it, it may already work. What car is that btw, was thinking on later putting my tab in my mustang, but tthe shaker audio system is wayy too good to screw up if i messed it up somehow, ill stick to that aux for now lol.
Sent either from my p113 (gtab 2 7.0) or i997 (Infuse)
P3110 does not have 3G. Just Wifi.
Sent from my GT-P3110 using xda premium
Sorry, I wasn't clear I meant 3g from teather (or 4g) Thank you anyway. keeping these numbers straight
P 3113
Hey Guys, thanks for the feedback.
Status is i got 3 things left to do now.
1: wait for my OTG cable to arrive and then install that, and hopefully i will be able to charge while using usb as host.
2: lift tablet 2 millimeters in the left side.
3: give my tablet black bezel, think solution will be electricity tape (i know it's kind of crazy to tape my brand new tablet). But after i placed the tablet where it's ought to be, the white bezel isn't as visible as on the picture above.

I live i Thailand where the 3g kind of suck, but i made speed and ping test on both tablet and mobile while using tethering, and there wasn't any notable difference between the tablet and the mobile. The GPS in Galaxy tab 2 is very good when comparing with other mobiles and tablets i tried, it connects to a lot of satellites right away. Bluetooth and microphone also works fine, so seems like i havent blocked for any connectivity

It's a Mitsubishi Triton GLS 2011 (aka L200), nothing special but a damn good truck for it's engine class (won the award for best high-lifted pickup).
One of the reasons i went for Tab 2 instead of Nexus beside the hassle i would have to order it from abroad, and all the problems i read people have with the tablet, is the DAC in this tablet (Wolfson). I might look into a digital audio solution later on, but for now it's analog audio transferred to the stereo. I love good audio, but not quite audiophile, but being in a vehicle i don't find it that important for now
I'll let people know if i find a solution for the charging while using USB as host!
Just a little image update after i taped the bezel black
Next up, OTG, USB hub and sd-card reader!
OMG this is really awesome. I want also want it in my car .
Really great, fantastic idea! :good:
Any news on this project ?
some pictures ?
and did you manege to made Y cable to charge TAB and have storage at sime time ?
If, is it posibile to have external USB DAC and charging at the sime time ?
(I heard thet there will be option to conect external USB dac to TAB 2 (3100,3110...)

Sorry about my late reply, i changed the Galaxy tab 2 out with a Nexus 7 instead which didn't solve the problem though, even with Timur kernel that doesn't really charge enough using OTG/charge.
With Nexus 7 it is possible to have USB DAC, but i think it is a little overkill to be audiophile when it comes to car sound unless you have a disco on wheels.
Anyway, my solution ended up being wireless storage and i can highly recommend this: http://www.amazon.com/RAVPower®-Wireless-External-Streaming-RP-WD01/dp/B00AQUMZRA which will also work fine with the Galaxy tab 2.
To make it a better experience then make sure you have a kernel that support cifs, or at least the module and then use app like CifsManager from play store to mount the storage as local storage, that way you can access the files within any application you wish.
Will take some new photos of the setup again soon, since the old ones have been removed.

Is it possible to have both reverse cam AND a dash cam hooked up at same time?

I'm planning on buying a Joying Android unit. I currently have a front-facing dash cam that has an AV port out that supports RCA in. I also have a reverse cam with RCA jacks. The Joying head unit only has 1x RCA Video-IN port ...is there anyway I can make it work so that both the reverse cam and front-facing dash cam will work with the unit?
For reference, here is the back of the Joying unit...

Dash cam on an Android unit needs to be usb I think
Verstuurd vanaf mijn ZUK Z2121 met Tapatalk
Dashcam does need to be USB indeed. What you can try is to use an "RCA to USB" converter cable. They are not that expensive. Search on Amazon, Aliexpress, eBay, etc.
Note though that AV/RCA outputs are low-res up to max 720x480 or 720x576. Any modern USB Dash cam has minimally 1280X720 or 1920x1080.
Also: You need to have a dash cam that does the recording/storage itself. USB saturarion on USB-2 happens quite often, although these low resolutions of 720x480/576 might have a way lower bandwidth usage.
Next to that: USB-2 is "half-duplex". Only one signal can travel the line, be it back or forth (like a walky-talky: "blahblahblah, over"). These units have only one USB-hub. PCs often have 2 or 3 usb hubs. In that case, if you evenly distribute your devices, the half-duplex occurs per hub, or only one hub has the saturation. Any other device using USB will break your video signal and thereby a correct video recording if you want to do that on the unit instead of on the dashcam itself.
It's a bit of a pity that the old carjoying forum no longer exists. There was a user who had 4(!) cams connected and who had nicely explained how he did that. (but of course: who needs 4 cams?).
Next to that it contained a wealth of info about dash cams and other solutions, like using a raspberry-pi 3 or pi-zero with Pi cams in combination with an apk on the unit. I have used that also for quite some time and that certainly allows for multiple high-res, high-bandwidth dash cams (pi cams) connected.

What are the chances you know what the carjoying forum site was called? It might have been archived. I would LOVE to know how that guy used PI's for dashcams with an APK.

I have already searched via the wayback machine, but it is really limited. You can find a few "broken" topics but not one complete thread.
the site was forum.carjoying.com.

Also: You need to have a dash cam that does the recording/storage itself. USB saturarion on USB-2 happens quite often, although these low resolutions of 720x480/576 might have a way lower bandwidth usage.
Next to that: USB-2 is "half-duplex". Only one signal can travel the line, be it back or forth (like a walky-talky: "blahblahblah, over"). These units have only one USB-hub. PCs often have 2 or 3 usb hubs. In that case, if you evenly distribute your devices, the half-duplex occurs per hub, or only one hub has the saturation. Any other device using USB will break your video signal and thereby a correct video recording if you want to do that on the unit instead of on the dashcam itself.
It's a bit of a pity that the old carjoying forum no longer exists. There was a user who had 4(!) cams connected and who had nicely explained how he did that. (but of course: who needs 4 cams?).
Next to that it contained a wealth of info about dash cams and other solutions, like using a raspberry-pi 3 or pi-zero with Pi cams in combination with an apk on the unit. I have used that also for quite some time and that certainly allows for multiple high-res, high-bandwidth dash cams (pi cams) connected.

Excellent info, thanks so much!
Quick question regarding the USB-hub comment. If I use an external USB-hub to enable two USB-inputs (the dash cam via usb-RCA and the TPMS System) from a single USB plug, will they both work without interference or will I have problems too?

It will have the same half-duplex problem, even if you connect 10 hubs. All hubs need to go through the single hub in the unit.
We need to wait for USB-3. It is full-duplex and so much faster. But in that case the CPU might become the bottle-neck in encoding the video.
You weren't joking about broken. LOL
I have been doing some research and found a few projects that use the PI for a dashcam or even some kind of Black Box. The issue is viewing the feed on an Android device/HU.
I'll do more research and see what I can find.
