Alexa Controls Optoma UHD51A Data Projector



Amazon might be planning a plethora of Alex-enabled devices over the coming months (according to CNBC and covered by Todd), but Optoma’s voice control into their HD projectors right now. Here’s the Alexa-supported 4K Ultra HD projector, UHD51A.

To get the boring out the way, the UHD51A is a very capable ultra HD DLP (digital light processing) projector with a resolution of 3840×2160, pushing out 2400 lumens, with High Dynamic Range (HDR) compatibility, two HDMI ports and HDCP 2.2 support. A 3000 lumens version is available in the US but not the UK.

The exciting bit is that the UHD51A can be controlled by Alexa with a range voice commands to manage both the projector itself and media playback.Here are some examples.

Alexa, turn on/off <projector name>
Alexa, change volume to 8 on <projector name>
Alexa, change input to HDMI 2 on <projector name>
Alexa, change input to VGA on <projector name>

For the built-in USB media player

Alexa, play on <projector name>
Alexa, pause on <projector name>
Alexa, next on <projector name>
Alexa, rewind on <projector name>

To be clear, the projector doesn’t have Alexa built-in and you do need an Echo or Dot to work alongside the projector, but it’s still pretty cool.

If you want to voice control your video, the Optoma UHD51A will set you back about US$1,699 or GB£1,549 on Amazon at time of writing.


Optoma ML1500 DLP Projector Review



Optoma LogoThe Optoma ML1500 DLP Projector is a stylish ultra mobile LED projector which pretty much does it all in a very neat little package with a good complement of ports, connections and fun tricks. Let’s take a look.

Optoma Front

Measuring just 27 x 17 x 4.5 cm and weighing only 1.4 kg, the ML1500 is very portable and comes with a neoprene carrying case. As you’ll see from the photos, the projector is attractively styled, with the ports on the back and a touchpad on the top. The touchpad can be used to operate the built-in menus to control the ML1500 and there is also a supplied remote control for when changes need to be made from afar. On the bottom, a third leg can be screwed in and out to adjust the angle, and a standard photo mount allows the projector to be hung from above. Finally, a lever on the side controls the focus.

Round the back there is a plethora of connections, with composite video, HDMI and VGA connectors, 3.5mm jacks for audio and microUSB, USB and SD card slots. Connect up the ML1500 to a PC or laptop and it appears as an Optoma WXGA (1280×800) monitor and with suitable OS, you can do the usual tricks of either reproducing the current desktop or extending the desktop to the ML1500’s display. Locking onto the VGA signal took a second or two, but nothing out of the ordinary. The small size of the projector meant that I could keep it on my desk and if I needed to have an impromptu team meeting that needed something shown, I could quickly turn the ML1500 onto a nearby wall, rather than everyone huddle round a monitor.

Optoma ML1500 Remote ControlOn the fun side, the ML1500 makes a good partner to mini media streamers like the Roku Streaming Stick or Chromecast. The stick can be plugged into the ML1500’s HDMI sockets and power pulled from an adjacent USB socket. All set and good to watch Netflix or other streaming service with minimum of fuss.

The ML1500 does a few other tricks up its sleeve (or USB port as the case may be). First of all, the projector has a built-in media player and office document viewer that will show films, play music and display Word, Excel, Powerpoint and PDF files directly from either an SD card or USB memory stick. I didn’t deliberately try to break the viewer but the ML1500 managed to cope with all the Office documents that I threw at it. It’s relatively easy to navigate round the documents and zoom in or out with the remote control. The on-screen menus are easy to navigate with large friendly icons showing the way.

Playing movies is cool too, with the ML1500 handling mp4, avi and mov format files (though I didn’t confirm the codecs inside each). The presentation is good with the projector keeping up with the action and the picture is fine in unlit room – it doesn’t need to be darkened. Obviously you can have a pretty big screen if you want – I watched a couple of films and really got into the cinematic feel of things. Colours were good and sound is ok – it’s not hifi but you can connect up via a 3.5 mm jack if you want more oomph.

Optoma WiFi DongleNext on the list of clever things is the USB wifi dongle which plugs into the ML1500. Once connected to the “Optoma Display” wireless network, you can use an app on your smartphone or tablet to play presentations and display media. I used WiFi-Doc on Android and the app is available for iPhone and iPad too. It’s easy to use – select what you want to show and it’ll be shown by the ML1500. You can zoom in and out of photos and documents, and about a second later, the projector will update to show the change. Here’s the app showing a photo of the house that Mel Gibson used while filming Braveheart. The app wasn’t quite as good as the built-in player when it came showing office files as a couple of pdfs had missing images.WiFi-Doc App

A final nifty feature was auto-keystone correction, where the ML1500 automatically adjusts the projection to account for the angle of the projector, which means that the picture on the screen is always rectangular and not fatter at the top than the bottom.

One minor niggle is that adjusting the focus has to be done manually and it can’t be corrected using the remote control. Not a big deal in most circumstances but could be an issue if the projector was mounted high up.

Although I’m not a projector expert, I enjoyed putting the ML1500 through its paces. Its comprehensive ports and built-in media player make it a good choice for both business and pleasure, and for those on the move, the low weight and PC-free capabilities, are attractive. I think it’s priced about right too at under £700.

Thanks to Optoma for the review unit.


Optoma Pico-Projector at The Gadget Show



Optoma specialise in digital projectors with a range going from personal pico-projectors all the way up to professional stacking projectors for large-scale installations. Here at The Gadget Show, Optoma were showing off their  ML750, an ultra-compact LED projector about 12 cm square and 4 cm deep. The picture below doesn’t get over how small the unit is.

James from Optoma runs through the features of the ML750, which with the addition of a small wireless dongle (the little white object in the top left of the photo) allows presentation and streaming directly from the tablets and smartphones over wi-fi to the projector. The feature works with both Apple and Android devices using a downloadable app.

The native resolution is 1280×800 but will show 720p and 1080i video sources. It’ll even do 3D with additional active shutter glasses, though I’m not sure anyone is interested anymore. Still, the feature’s there.

I’m not a big projector expert, but at the event the ML750 was showing a series of film clips and it was very watchable. Obviously nothing like an HD monitor but for a portable device showing a 32″ display, it was impressive.

Available online for GB£400.


TP-Link ACes Wi-Fi at The Gadget Show



Like many families now, it’s not unusual for everyone to be using the wi-fi network at home at the same time. Game consoles, tablets, media players and smart TVs all take their share of the data stream, and with the potential for multiple HD streams, the wireless takes a real hammering. In response to this demand, 11ac wireless uses dual frequencies and multiple antennae to get gigabit class data speeds, while still being backwards compatible with the older standards.

Under the Archer brand, TP-Link have a range of 11ac routers and modems, starting with twin antennae 750 Mb/s Archer C2 up to the three antennae 1750 Mb/s Archer C7. TP-Link has kindly sent one of the latter to GNC for review, so I’ll be taking a look at that later.

At The Gadget Show, I caught up with Simon from TP-Link who told me a little about their design philosophy and what they’re aiming for with the new 11ac routers.


Updated Western Digital DVR Expander



For those of you with a cable or satellite DVR or TiVo, Western Digital has updated their My Book AV DVR Expander hard drives.  Among other things, is the addition of a USB port, to the already existing eSATA port.  That means the drives are now compatible with the Sony PS3 and other media devices such as camcorders.

This is TiVo’s one and only “official” method of hard drive expansion.

The capacity has not changed – it’s still 1TB, but I think we can expect that to be expanded on in the near future.  Although, 1TB is an awful lot of HDTV recording.  I never came close to filling the 500GB drive in my DirecTV HR23.

One thing to watch out for, at least for DirecTV users (and I have no idea if this applies to other DVR’s) is that this drive replaces the internal drive.  The good news is that it replaces, but doesn’t overwrite.  In other words unplug this drive and reboot to the original internal drive and all of your previous recordings are still there.  It would be nice if it added to, instead of replacing, but beggars can’t be choosers.  And, since most cable DVR’s have ridiculously small drives, this is a no-brainer of an upgrade.

So, what do you pay for this convenience?  It retails for $149.99, but Amazon already has it for $119.00.  This is what we should have from our TV providers to begin with, but, for now, we  have to pay extra for.  And this is, by far, the best extra you can add to your DVR.
