Happy Printer a wireless, inkless, portable fun printer!

Happy Printer with Zink inkless technology
Happy Printer with Zink inkless technology

I was researching DIY photobooths for possible set up at my son’s prom when I came across this cool little printer called the Happy Printer from Zink.

It uses a heat activated ink less color technology developed by a spin off from the old Polaroid Company. Its kind of like the label printer I have that used special heat activated label. The great thing is there is no ink to purchase.

The Happy Printer uses rolls of special paper in a variety of widths such as two inch, one inch, 3/4 inch and 1/2 inch. The rolls are about 20 feet long and there is even an app available to “stitch” strips together if you need a bigger print.

And if printing off little color photos or strips of photos isn’t enough fun, did I mention that the paper is also a sticker? Double the fun when you can stick the result right into a scrapbook project or on a lunch bag.

There are two versions of the Zink Happy Printer currently on the market and a number of other little portable printers that use the Zink technology.

The ZINK Wi-Fi Enabled Wireless Printer with Arts and Crafts App sells for $99.  ZINK hAppy Smart App Printer hAppy is the portable, Wi-Fi, app-accessory that allows you to print directly from smart phones and tablets. Just download the free ZINK Design & Print Studio app onto a smartphone or tablet (or use a 3rd party compatible app); load a ZINK zRoll™ (photographic-quality ZINK Paper in roll form), design, and then wirelessly print to the hAppy. It’s compatible with iPhone, iPad, and iPod touch. hAppy is also compatible with Android smartphone and tablets and Amazon Kindle Fire tablets. hAppy works with Apple AirPrint and Google Cloud Print apps.

The ZINK Wireless Touchscreen Printer. Wi-Fi Enabled. Built In App for Editing and Printing Photo & Labels On-The-Go. Prints Directly and from IOS & Android Smart Devices sells for $199 and adds a touch screen for creating images right on the device.

ZINK hAppy+ Smart App Printer. Featuring the Google Android operating system, the hAppy+ has built-in Wi-Fi, a touchscreen, and runs ZINK apps, making it your all-in-one tool for designing and printing whatever you can imagine, all from the palm of your hand. Via built-in ZINK apps, users can create and print directly on the hAppy+ without needing other devices. Just load a ZINK zRoll; create the design on the printer’s touchscreen; press print; and then place and adhere the print to create a variety of projects. hAppy+ is also compatible with Apple AirPrint and Google Cloudprint. The hAppy+ can also work as a companion to smartphones and tablets.

Zink stands for  “zero ink” is a full-color printing system for digital devices that does not require ink cartridges and prints in a single pass.  The printing technology and its thermal paper are developed by Zink Imaging, Inc., a US company. Zink Imaging makes all the paper; makes a printer for printing labels and other designs on rolls of Zink zRoll; and licenses its technology to other companies that make compact photo printers, and combined camera / compact photo printers that print photographs onto mostly 2×3” (about 5×8 cm) sheets of Zink Paper.

The Zink technology and Zink Imaging started as a project inside Polaroid Corporation in the 1990s, which spun out Zink Imaging as a fully independent company in 2005.

Happy Printer can be synced with Photobooth apps like Photobooth and SimpleBooth to create a photobooth for events.

Other Printers That Use Zink Technology

There are a number of small, mobile printers (and instant cameras like the Polaroid Snap) that use Zink’s inkless technology but they use sheets instead of rolls of the Zink paper.  Instead they use packs of 10 sheets at a time.  I don’t like this method as much as the Happy Printer’s long rolls but here are the options.

Grip Gear’s Movie Maker Set

Grip Gear’s Movie Maker Set – Electronic Sliding Track System with Variable Speed and Motorized 360° Panoramic Time Lapse Head compatible with Smartphones, GoPros, Digital Cameras

This is rather cool.  A professional motorized slider for smartphones, small action cameras and compact camera for less than $100.  Hope to get my hands on one soon to test it out.  – Ed

Shoot stunning video with your smartphone or compact cam. Use with tracks as an electronic slider with 8 different speeds, or use stand-alone for stunning 360° panoramic shots. Even the shortest clips look professional in realtime or timelapse.
Whether you’re aiming for making a viral, online revelation, adding drama to your video or simply want to out-focus and out-shoot your peers, no need to wait for the perfect spot or perfect moment to experiment with this tool. Watch the video clip in the thumbnail menu above to see The Movie Maker in action.

WHEN TO USE A SLIDER?

Make a reveal Film a reveal of a product by having it hiding the view and then slide from it. It will create an expectation from the viewer and be more surprising. Great technique for ‘unboxing’ videos, sliding close-up or textures and other detail.

Zoom in and zoom out Conventional zooming in and out doesn’t include movement. With a slider you can move forward and backward which gives it a great effect, allowing the viewer to be more involved.

In and out of focus Begin the shot with a blurry subject revealing itself by the movement of the camera on a slider. This is a variation from the more usual focusing effect.

Play with foreground and background Using a slider with a foreground will give the viewer a better sense of depth. It makes each layer move at different speeds and enhance the field of depth experience.

Close ups anywhere Anything shot at close range with a slider will show off great detail: Whether textures, nature, a detail on jewellery, the sky is the limit, close-ups with a slider will make viewers pay attention to details we usually overlook.

Electric Snow Shovels and Electric Snow Blowers

 

 

Due to climate change we haven’t had winters like we had in the past.  In fact the last two winters had such little snow that I shoveled the driveway by hand.  And my son’s cross-country ski team had to deal with cancelled and delayed meets.  Even this year practices early in the season were mostly running and training in the gym or skiing on a dusting of snow on the artificial turf of the football field.

But now in mid-February we got a string of snow storms that dumped a couple of feet of snow on us.  I’ve been keeping the deck, driveway and front walk clear of snow using a good old fashioned shovel – which is great exercise and a nice and quiet way to enjoy the silence of a snowy day but also with an electric snow shovel and an electric snow blower.

My electric shovel is probably 12 years old now.  I got it originally for vacation house in the North Conway area.  My electric snowblower is more recent.  After dealing with a gas powered, noisy, hard to start and frequently breaking down snow blower for years, I sold it at a yard sale and got this electric one.

We had a long driveway in Maine so the gas powered blower was required but here in New Hampshire the entire driveway is reachable by a long electric cord.  The gas blower was two stage and more powerful then the electric blower but so far I haven’t run into any storm that it can’t handle, as long as you go slow.  The gas blower will chop through anything with its metal blades while the electric blower is made of hard plastic and is designed for smaller jobs.  But still its been fine and best of all its quiet and starts immediately.  Plus there is no gas to mix and spill.

If you have a smaller area to blow and don’t have killer storms, I highly recommend an electric snow blower and shovel.


 

 

 

The Best SD Card for your GoPro Hero5 Black or Session and DSLR

Ok, you’ve bought your new GoPro Hero5 Black or Session action camera. Congratulations you have one of the newest and most advanced action cameras on the market. If you are like me maybe you bought a 32 gb memory card or something for it and have quickly found out that you are always wanting more storage.

There is nothing worse than having to replace an SD card the size of a finger nail in the middle of a fun day of shooting. For me, I’m thinking of my upcoming 10 day trip to Iceland. I’m not going to have a way to download video off the card while traveling. I’m going to need a lot of storage and I’m going to need a lot of it – plus I want fast transfer speeds to there are no glitches. Bottomline I want big and I want the best, that’s why I’m going with the Lexar Professional 1000x microSDXC 128GB UHS-II/U3:

The GoPro Hero 4, the Session and newer, all support cards up to 128GB. Do you need such a big card for a day of shooting? Probably not. You could get away with a 64 gb card and a lot of extra batteries but for multiple days of shooting, consider 128 gb card.

Consider the difficulty of swapping cards on the GoPro Hero 5, it’s a little more difficult to change out the cards compared to the other cameras since the bottom door is a little difficult to open and usually your camera will be inside some sort of holder. So if you use you’re camera a lot, you’ll likely fill a 32GB card and have to interrupt a shoot to swap it. In this case, I would recommend a 64GB card which should get you through the day.

 Lexar® Professional 1000x microSDHC™/microSDXC™
Lexar Professional 1000x microSDXC 128GB UHS-II/U3 (Up to 150MB/s Read) W/USB 3.0 Reader Flash Memory Card LSDMI128CBNL1000R

Specs:

High-speed performance-leverages UHS-II technology (U3) for a read transfer speed up to 1000x (150MB/s)

Includes micro SD UHS-II reader for high-speed file transfer from card to computer, dramatically accelerating workflow

Premium memory solution for sports camcorders, tablets, and smartphones

Designed for high-speed capture of high-quality images and extended lengths of 1080p full-HD, 3D, and 4K video

Includes lifetime copy of downloadable Image Rescue software

 

DSLR SD Memory Cards

Cameras keep coming out with bigger and bigger megapixels sizes.  The resulting files are YUGE so that’s why I’m upgrading to a larger and faster SD card for my DSLR to quickly capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video.

Lexar Professional 1000x SDHC/SDXC UHS-II cards Quickly capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video
Lexar Professional 1000x SDHC/SDXC UHS-II cards Quickly capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video.

Don’t need extreme speed?  Save some cash with a slightly slower card.

For my Canon 6D DSLR I don’t need extreme speeds.  This SanDisk Extreme PRO 64GB SDXC Flash Memory Card provides very fast transfer speeds for a reasonable cost.

Or this bargin from Lexar – a two pack for a bit more than a single SD card.

The new Lexar Professional 633x SD cards are an update to the 600x SD cards. The cards meet the UHS Speed Class 3 (U3) specification that is given to cards that support 30MB/s or higher continuous write speed, a requirement when recording 4K video.

The Lexar 633x cards are quoted at 95MB/s read and 45MB/s write write speed, essentially the same as the 90MB/s read and 45MB/s write of the 600x cards they replace. The 633x cards are available in 16, 32, 64, 128 and 256GB capacities (the 16GB card has 20MB/s write speed). This review is for the 633x 64GB SDXC card.

Essential Winter Photography Equipment – A good pair of boots!

Winter Boots – I typically review photography equipment but the recent dumps of snow we’ve gotten lately (more snow than the last two years!), has made me re-evalute my winter footwear equipment.

At this point we have an inch of ice as a base layer followed by six inches of crust and then a layer of about 8 – 12 inches of fluffy snow.  On the sides of the road we have waist high snow plow created berms and then anything between ice and waist deep drifts of snow in the fields.

Time for new winter boots!
Time for new winter boots!

I can no longer keep putting off new winter boots.  My last pair must be about 10 years old and the soles are nearly worn through, the laces are long gone and water is seeping through holes in the sides.

I have several pairs of shoes for the winter:

A short pull on sneaker like shoe with very aggressive soles for when I’m walking in shoveled area. Mine are kind of like these from Merrell but mine were made by Salomon and have an even more aggressive soul.   When they came out on the market they were an entirely new kind of shoe.  Something you could slip on to go from the ski lodge to the car.  I don’t know why they stopped making them, they were very unique and different than anything I’ve seen since.  Mine and  my wife’s pairs are still going strong after about 12 years of use in the snow.

A mid-height insulated “duck hunter” type boot that great for wet sloppy stuff.  But I don’t like fiddling with the laces!

And a tall winter boot for deep snow, snowshoeing and snowblowing/shoveling the driveway.  Plus for jumping over banks and into drifts of deep snow to capture some winter photographs.

My criteria for winter snow boots is the following:

  • They have to be warm.
  • They have to be waterproof, at least on the bottom few inches.
  • They have to be easy to slip on and off as I’m going out to get firewood and have to come in an out several times.
  • They have to have a good grip on ice and snow.
  • No laces – I’m done with having to lace them or having the laces break constantly or come undone.
  • I have to be able to drive with them on.

I ended up getting these as my replacement for my old used up Sorrells.

Its a basic boot that meet the criteria I need to attack the drifts and climb the snow mounds.  Thick sole, high sides, no laces other than a pull string at the tip to close up the boot to snow, dirt, salt crystals or whatever.  Easy to pull on and off these will be great for tackling the rest of the winter season.

Classic Vintage Film Cameras

I’ve always enjoyed my position in history in terms of technology. In middle school I enjoyed the dawn of the home video games, we had a Pong and then later a Magnavox Odyssey², which my Dad liked over the Atari system because it came with a keyboard and perhaps had more educational opportunities.

I graduated High School in 1984, just when personal computers were becoming mainstream.  The report card system still used punch cards!  In my first year at Boston University, I did have a class that required sending stat problems to the mainframe computer for batch processing.  By my sophomore year you could rent time on an Apple computer to work on papers. By the time I graduated just about everyone had their own home computer or laptop.

During this time I also used film cameras, developed my own negatives and had a closet darkroom set up.  In High School I had and Olympus OM-10 35mm film camera and then after that fell in the lake I got an Olympus OM-G.

My first online purchase was an old 4×5 Graflex Crown Graphic press camera that shot Polaroid Type 45 Positive/Negative film with and developed in a bucket.

When digital cameras rolled around, I wasn’t an early adopter.  I was busy with a career in the Computer Magazine Publishing Industry which was seeing an upheaval.  Instead when my son was born I bought a Sony video camera and took a lot of video and had a small digital point and shoot camera.  It wasn’t until years later that I had time to get back into photography and purchased a Panasonic Lumix G Series mirrorless camera and started to take serious photographs. Later I added a series of Fujifilm small cameras and a full frame Canon 6D DSLR to my equipment.  My most recent addition has been a GoPro Hero5 Black action camera. The world of digital technology is always exciting and I’m glad I lived in the pre-digital, vinyl record, cassette tape analog world growing up to really appreciate what we have now.

Budget Action Cam, the Polaroid Cube

Looking for a fun action cam but have a small budget?

For budget minded consumers, people wanting to test the waters of action cams, kids and maybe even those who want to keep things simple and cost effective, the Polaroid Cube is a fun little action camera that actually takes some decent HD video.

Here is a good review of the original Polaroid Cube to get an idea of its capabilities.  The original can be had for around $60.  The new version which adds image quality/resolution and WiFi capabilities is around $100 – $130.

The newest version of the Polaroid Cube adds 8mp stills (up from 6mp) and in creases the video resolution to 1440p well as adding Wi-Fi and Video stabilization, all for $100 less than GoPro’s similarly configured Session camera.

The camera is weatherproof out of the box and for $25 you can get a waterproof housing for underwater shots.  For $25 you can get a bundle of mounts, many of which work with GoPro style mounts.

If someone just getting into action camera or for kids or people looking for a bargain camera, this Polaroid Cube+ fits the bill.

GoPro’s Karma Drone Relaunch

GoPro recently reintroduced its Karma Drone after its initial crash and burn back in October.

It seemed like a perfect product line expansion to take its leadership position in small action camera and give them wings.  Drones produce amazing footage and the hobby of flying drones is growing like crazy.  Since GoPro already offers a great little camera, why not grab some of the drone market?

Unfortunately the first release of the Karma Drone had a battery connection problem.  Suddenly in mid-flight the drones power could cut off and the drone would fall to earth as fast as the laws of gravity bring it in for a dirt kiss.

Suddenly YouTube was full of crash videos like the one below and the product was recalled.

The recall created a crisis situation at GoPro including layoffs. Changes were made to the product line. Now instead of a confusing line up of multiple versions of the action camera there are now only three variants. The GoPro Hero5 Black, the flag ship product, a waterproof case and LCD touch screen back as well as two versions of the very small cube like one button camera called the GoPro Session.

Now the redesigned GoPro Karma drone is back on the market with a fix to its battery connection. Interesting and good news for existing owners of a GoPro Camera, you can order the Karma with a camera, with just a camera gimble or even without a camera or gimble if you are just interest in flying the drone around without taking video.

You can also buy the GoPro Karma Grip which is the gimbe on a stick for steady video while hiking or walking. Karma Grip’s camera stabilizer can be easily detached from the grip and attached to the Karma Drone for stabilized aerial footage.
