Hi,
Just testing this still works. ;)
Best regards

I needed a shim between the Fujinon fisheye and my one piece C mount to Pentax Q adaptor.
Re-using the black rubber o-ring seal from the silver metal adaptor out of the Axis security camera was very handy. It is offering just the right flex to allow for smooth focus adjust that has enough resistance that stays put when I want it to. Acts like a makeshift helicoid I suppose. Give it a try if you did not throw out your o-ring already. Otherwise a similar size o-ring would do the trick.

Glases Free 3D photo editing with StereoPhotoMaker


http://www.youtube.com/watch?v=oIcWst8t1co

Was wondering if it was possible and potentially very cool... to use  one of my glasses free 3D screened Android devices as a preview window whilst editing 3D images using SPM (Stereo Photo Maker). With very little faff, I got it to work almost exactly as I'd wanted and here is what I came up with... Maybe some of you are interested.
You need a Windows PC with SPM. Mine is Windows 7 laptop.
A glasses gree 3D screened Android device. The example I used here is a HTC EVO3D (available cheap off eBay). Install the iDisplay app on both PC and Android from Google Play store.
USB data cable serves 2 purposes. It allows a stable wired connection for passing screen data from PC to Android display. Secondly, it provides some welcome power to charge your android device while it is connected. The USB line between the PC on the phone isn't mandatory, iDisplay's extended display functionality can work untethered via just WiFi alone!!!
Have a manual way to switch on the parallax barrier on the glasses free Android device. I used Jmz3D Switcher to manually enable the 3D barrier on my rooted EVO3D. There is a similar utility for the Gadmei 8" 3D tablet thats also available from the Google play store.

Would not surprise me if this worked on a Gadmei 8" 3D screened tablet too. I don't have one to test but tell me if you have one and have tried this. Check out "Gadmei 3D Activator"

If SPM can use a secondary non-primary monitor for full screen preview... this would be (IMO) even more awesome. Anyone know how to do that? I have looked into it on the current version of STP and seems a minor annoyance I have to put up with for now, but I'll show the creator of SPM and find out what he has to say about future support...

New improved PQI Air Card II?

The original Air Card has been around for some time now, so an update would not be surprising. And right on queue, at least as of early Jan 2014, the PQI website has been quietly showing images of the new Air Card II product. Some Googling around suggests murmurs since as early as Step 2013 even. The obvious physical differences are a new blue body and more dramatically, a new 90° transposition of the microSDHC slot.
Unlike the original Air Card's side slotted design,  the new version has a rear ended access point, allowing users to conveniently swap out the MicroSDHC card without need for ejecting the Air Card from the device it is already inserted. It is certainly an improvement I am very interested in. Notice the new card has added the SD card read/write protection switch on the side too, which is a handy feature the original missed out on.

There are no other indications of any additional internal changes since the original design, but even so, I'd still wait for the newer version puely for the relocated slot positioning. The Air Card was already attractive for its novelty of letting users upgrade the memory with their own larger and faster MicroSD cards as they pleased. None of my existing SD WiFi cards let me do that.

Some fantasy features I'd hope the newer AirCard II brings would be faster U1 microSDHC even microSCXC card support, 64G, even 128G card support, improved power efficiency and faster WiFi transfers... But realistically, PQI has not promised us any of these. Just my wishful thinking.

There is a WikiDevi entry that makes mention of the newer Air Card II but nowhere else. PQI Air Card II (A201) - https://wikidevi.com/wiki/PQI_Air_Card_II_(A201)
Since finding out its existence, I have been searching local stores but they only stocked the original version. I finally contacted the local distributer for PQI products but disappointingly, even they were unable to give a release date.

Let's keeps our eyes peeled for this new revision of this WiFi enabled SD card.

If you work for PQI, please get in touch with me because I want one! Yesterday!

EVO 3D different camera modules

Both taken from EVO3Ds one on left is international, the right is a Rogers.
I gathered that HTC originally included twin 5MP sensor cameras in the EVO3D when it was first released. Wow... Twin 5MP 3D camera on a smartphone. That is some clever marketing. If you read the details though, the 5MP sensor was only ever fully exploited for 2D photos. The HTC's included camera app limited it's 3D photo captures to just 2MP 16:9 ratio at 1920x1080 resolution. Which on paper is fair enough, matches the 1080p HD TV standard. Video recording resolution for both 2D and 3D , is maxed out at 16:9 ratio at 1280x720 720p. Since the second rear facing camera sensor was only ever engaged for much lower resolution 3D photo and video capture, the EVO3D would practically never get to use most of the available 5MP. Such a waste... So did HTC release a wonderful new firmware to unlock full 5MP 3D photo and 1080p 3D video capture? No. From an unspecified date, they instead took the opportunity to out a cost effective hardware revision that quietly substituted that one underused 5MP sensor with a lesser 2MP sensor instead. Although the packaging won't indicate it... If you have a unit that rolled off the factory floor late in the EVO3Ds production run, there is a good chance you have a 5MP+2MP version. Looking at the phone settings you'd be forgiven for thinking it was still 2 x 5MP too, and functionally, most people probably won't ever noticed the switch. But knowing it bugs me... Dredging the internet, I'd found some folks on XDA forum had a made public an interesting tweaked Amaze camera app for Gingerbread EVO3Ds that would boost the 3D photo to 3MP 4:3 2048x1152. Still not the full 5MP but I'll take it. The app also has options to boost the bitrate of the 3D 720p video recordings up to an impressive 20MBs. Which should mean nicer looking video output. The app has 2 builds: if the 2048x1152 version crashes, it is indicative that your Evo3D has a 2MP second sensor. So this was one way to tell if an EVO3D is an early 2x5MP model or not. Unfortunately, the Amaze canera app only works for Gingerbread. The Evo3D I had was already on ICS, and sure enough, the tweaked camera app would force close every time I tried to open it. I had no way to tell if my EVO3D had 2x5MP rear facing camera. 

I only recently aquired a second EVO3D and was delighted to noticed some differences between them. 
A) X515m is on stock ICS made in Taiwan, red trim around rear facing camera  
B) X515a Rogers is on stock Gingerbread made in China, gold trim back

Inspecting the rear facing cameras, even without removing the back cover, I saw that the Rogers version has more recessed lenses vs the International version. I then proceeded to take them both apart to get a better view of the camera modules themselves. The one on the right with the impressive solid cast metal brace is quite possibly a latter 5+2MP module, it makes perfect sense as a logical enhancement. That once set in place, the sensors should be held securely positioned and well protected from potential shocks that may knock the 2 lenses out of alignment and cause less than optimal 3D capture. I'm hoping the less robust looking module that lacks such reinforcement on the left is perhaps indicative of an older version,but hopefully has a better chance of housing twin 5MP cameras.
The 2 modules have physical connections looking much the same and might be directly interchangeable. We shall see. Testing the Rogers with the tweaked camera app, it could only run the 1920x 1080 version, so it seems to be a 5+2MP module. Want to know more? I just found this article in XDA and worth a read http://forum.xda-developers.com/showthread.php?t=1646832

Spot the difference

The 1st image is taken from the eBay Posting. Seller name is deliberately cropped for now. I have saved screenshots.




Here is what I actually received. 
It may still be a usb smart phone dock but pictorially it bears no resemblance to the deceptive image that was used in the original eBay listing. I will be demanding a full refund and return.
