littleBits - STEM Learning Toys for Smart Kids

There's a big push to encourage science and technology education, under the acronym STEM (Science, Engineering, Technology, and Math). This has helped to drive innovation in educational toys for kids that can serve as a gateway to STEM, helping kids to learn by doing and by engaging with tangible physical objects, while still having fun.

One such product, the littleBits electronic building blocks, is seeing success -- reporting, for example, that up to 40 percent of kids using its kits are girls, four times the industry average.

The littleBits electronic building blocks, first released in 2014, allow kids to engage with electronic circuits by embedding a collection of electronic modules into "Bits" -- small circuit boards that simply snap together magnetically, so no icky wire wrapping or soldering is required.

There are some 70 different bits now available, along with 10 pre-packaged themed inventor kits.

The individual bits are priced starting at $7.95 and $9.95 for basic bits, around $17 to $25 for more complex bits (temperature sensor or servo motor), and up to $39 and $49 for specialty bits (MIDI or MP3 music). These are designed for ages 8 and up.

You build your invention by snapping together the four kinds of bits -- power bits to power the chain, input bits to control the following bits, wire bits to route and change the flow, and output bits to do something at the end.

The input bits include touch controls like buttons, switches, and sliders, sensors for light, motion, and sound, and sound generators like a keyboard and micro sequencer.

The wire bits can perform logic (e.g., and, or, not), fork the signal on multiple paths, and communicate wirelessly to other bits via radio.

Then the output bits display light like a bargraph or number, generate a sound with a buzzer or speaker, or can be in motion, from a fan to a DC motor.

Newer bits can perform even more sophisticated actions that bridge from toy circuits to smartphones and computers. These include taking input from a microphone or MP3 player, communicating using USB or Bluetooth, sending/receiving signals from the Internet, and programming with mini-computer bits (including an Arduino processor).

littleBits also has packaged a variety of kits with a selection of bits for different themed types of inventions. You can get started with Hall of Fame starter kits ($39), a Rule Your Room kit for touch-based inventions ($79), and a Droid inventor kit for creating robots ($99).

The new collection of Inventor Kits include the introductory Base Inventor Kit to build an intruder alarm or voice-activated robotic gripper arm ($99), the Electronic Music Inventor Kit to experiment with electronic instruments from a keyboard synth guitar to a hands-free air drum ($99), and the Space Rover Inventor Kit to customize a planetary rover ($199).

There's also an Avengers Hero Inventor Kit to build high-tech hero gadgets ($149).

littleBits also has packaged kits for educators and classrooms, and has developed over 20,000 school partnerships and 300 invention clubs.

AirSelfie2 Portable HD Flying Camera

The AirSelfie2 Portable HD Flying Camera is a small drone with a build-in forward-facing camera that is designed to make it easy for you to shoot photos and videos of small groups -- especially when there are too many people to shoot with your extended arm or a selfie stick (and you really need a wider and higher angle anyway).

This second edition of the product includes two key features from pro drones: auto stabilization, so it can hover in place automatically without you needing to constantly tweak the controls, and auto tracking, so it can lock in on your face and keep you in the view even as you move.

Neither of these technologies work perfectly, but they still are quite helpful for making it easier for you to keep it in position while you're trying to set up a shot. In particular, the AirSelfie2 can still drift as it hangs in the air -- typically moving slowly so that it is easy enough to correct with small tweaks, but sometimes and inconsistently worse.

The unit is palm-sized and quite small and light, at 3.8 x 2.8 x 0.5 inches and 2.8 ounces. It can be used outside, but really only in controlled conditions without wind.

You connect to it using its own built-in Wi-Fi hotspot, which should work to a distance of 65 feet, but a distance of more like 20 feet is recommended.

Then use the AirSelfie2 app to control the drone. You first launch it by tossing it gently in the air (from your palm), and land it by descending to your palm or the floor.

It has three choices of flight modes, from tapping buttons for each change in motion (move forward/back, move left/right, or rotate left/right -- all while maintain a level orientation), to joystick mode while tilting your smartphone. You also can raise or lower the speed of movement to work better with the environment and your dexterity.

The AirSelfie2 uses bottom-facing camera and sonar to control its motion, so the company suggests that it works best in a well-lit environment, over flat and multicolored surfaces, and without sound-absorbing surfaces (rugs). Even so, it can handle flying over furniture and other obstacles of different heights and textures.

As you are flying with the AirSelfie2 app, you can monitor the live video from the camera, and tap to shoot photos (or photo sequences) or record video clips. It has a reasonable 12 MP camera with 81 degree field of view, and shoots 1080p HD video (1920 x 1080).

The AirSelfie2 flies for around 5 minutes on a charge. The base product is $199, and there also is a PowerBank accessory (bundled with the AirSelfie2 for around $220) that can recharge the unit 20 times in the field for a total flight time of 75 minutes.

Depending on your propensity for taking selfies of you and groups, you may not have a compelling need for the AirSelfie2 to capture better selfies. But it sure is fun, and a very promising implementation of advanced flight assists in an inexpensive drone.

D-Link Wi-Fi Cameras

Video cameras are becoming quite popular for do-it-yourself home security, with "smart home" products like the Ring Doorbell cameras and the Blink Indoor and Outdoor cameras (acquired by Amazon at the end of 2017). These are designed to monitor an area, send an alert if they detect activity, and post an associated video clip online.

These cameras are designed to be small and inexpensive, and so depend on the web for storage. As a result, they tend to capture relatively short clips, limit the amount of video storage, and/or charge a monthly fee for storing clips for longer periods. They're also not designed for extended live viewing.

But these security cameras are great for their purpose, and you can spend lots of time on YouTube watching clips of people who were successfully caught acting badly at front doors -- trying to break in, stealing packages, and hogging all the Halloween candy.

Another approach, taken by D-Link, is to build the intelligence and the storage into the camera, with online cloud storage as an option. These cameras detect activity, record clips to a local SD card, send alerts to your smartphone, and optionally upload the video to the cloud. Plus you can monitor them live, continuously, and record while watching, for example to keep an eye out on the driveway for an expected visitor or package delivery.

The D-Link cameras also provide a broad range of configuration options, through the mydlink app and web browser access, including remote viewing with zoom, split-screen to monitor multiple cameras, detection sensitivity (sound and/or motion), selecting zones within the view to monitor, alert types, and use of night vision lighting with IR LEDs. The app also works with Amazon Alexa (Fire TV) and Google Assistant (Chromecast).

The core D-Link line has four wireless cameras.

The base D-Link Mini HD Wi-Fi Camera for $59 (two for $99) is small cylindrical camera (3.6 inches tall) designed for indoor use, and which records only to the cloud.

It captures HD 720p video (1280 x 720), with a 120 degree field of view. It alerts on sound or motion, and the night vision IR LEDs illuminate up to 16 feet in complete darkness.

The D-Link HD Wi-Fi Camera for $59 is an adjustable camera with similar specs and about the same height, but stores video locally and optionally to the cloud.

It also not only records audio with video, but also has a speaker to support two-way conversations.

The D-Link Full HD Wi-Fi Camera for $79 then steps up to higher-res 1080p Full HD video (1920 x 1080).

It has a wider 130 degree field of view and is a bit taller at 4.3 inches.

Finally, there's the D-Link Full HD Pan & Tilt Wi-Fi Camera for $99.

This is a 1080p camera with 114 degree field of view. It's a bit chunkier at 4.38 x 5.26 x 4.58 inches, and 0.73 pounds.

Plus, it adds the ability to see a much wider area by remotely panning side by side to see behind (170 degrees to each side) and tilting it up and down (up 90 degrees to look straight up and down 20 degrees).

The D-Link setup process is relatively painless. You download the app, scan the QR code on the camera to identify it, and then set up the camera on your Wi-Fi network (done transparently through Bluetooth, so you don't need to manually mess around with settings). This worked successfully in most of my tests, although sometimes the app needed to re-try the Wi-Fi setup. Just watch out that there are multiple "mydlink" apps in the app stores (Lite, Home, etc.) -- you need "mydlink" without any modifiers.

Finally, D-Link does provide monthly plans for its cloud storage option, which are designed for extending storage for multiple cameras. You can store video for free for 24 hours, with up to 3 cameras. You can extend this to 7 days for $2.49 a month or $24.99 a year, or 14 days with 5 cameras for $4.99 / $44.99, up to 30 days with 10 cameras for $9.99 / $99.99.

Smart cloud security cameras are a great inexpensive alternative for alerting on activity in specific areas like the front porch. But for not much more you can get a more flexible camera that allows you to watch areas live, provides more flexible control over how it monitors, and stores and retains video locally without additional monthly costs.

Plantronics Bluetooth Headsets

Bluetooth wireless earbuds are the minimalistic approach to personal music, with just the two small earbuds (see previous post).

But the small size means tradeoffs, including shorter battery life. If you are looking for other alternatives, Plantronics offers a wide range of listening products, both single-ear earpieces used mostly for phone calls, and stereo headsets and earbuds in a variety of styles - in the ear, over the ear, over the head, and behind the head -- and for use in the office and for travel.

In particular, these Plantronics products are designed for extended music playback and can help you relax on long trips with extended listening times (8+ hours), voice assistant integration (Apple Siri or Hey Google), and built-in active noise-canceling (ANC).

ANC provides clearer audio in high- and low-noise environments, especially by filtering out low frequency noises like AC, fans, motors, and buzzing electronics. The noise-canceling level can be controlled from the Plantronics Backbeat app, along with selecting balanced or bright EQ modes.

For longer use in earbuds, the Plantronics BackBeat GO 410 Earbuds add a flexible neckband that sits behind your head, with cables running up to the two earbuds.

This design provides the space for extended use -- up to 8 hours listening with ANC, and 10 hours without ANC. And it allows the use of additional electronics, especially the active noise-canceling and voice assistant integration.

They also allow you to insert and remove the earbuds easily. When you remove them, they snap together magnetically to hang out of the way, which also turns off ANC and disconnects Bluetooth to save power. And unlatching them will automatically re-connect Bluetooth and answer an incoming call.

The power cable also is dual-use - the USB charging tip pops off to convert the cable into a standard 3.5 mm audio connector, so you can still use the earbuds with a wired connection even if the battery is dead.

The BackBeat GO 410 Earbuds are available for around $129, in black and white.

Then, of course, the best way to isolate yourself on a long plane trip is to use over-the ear headphones, like the Plantronics BackBeat GO 810 Headphones.

These are designed for commuters and travelers, with up to 22 hours of listening time with ANC, and 28 without ANC.

They have a slim over-the-ear design with memory-foam padding, weigh only 7 ounces, and fold flat for travel.

The earpieces have room for multiple controls, including volume, skip tracks, and take calls, plus manual controls including select EQ presets, ANC on/off, and activate voice assistants.

The headphones support an extended range Bluetooth connection of up to a 164 feet with compatible devices. You also can connect to two devices simultaneously and stream from either one.

The Plantronics BackBeat GO 810 headphones are available for around $149, in blue, black, or white.

Either way, you can have comfortable extended listening, and still be able to move around without being tethered to your smartphone or tablet. The active noise-canceling is a nice bonus, and without the strong pressure you have felt with older products.

Altec Lansing True EVO Wireless Earbuds

Beyond wireless portable speakers (see previous post), the best way to hear music is to put the speakers directly in your ears, as wireless earbuds. These are truly wireless, with no cable between the two earpieces and no cable to the audio player.

The issue, of course, is that the earbuds need to be small and light to fit comfortably in your ear, but also need to hold a large enough battery to last for a reasonable length of time. Plus, the earbuds are so small that it's tricky to keep them safe and accounted for when you take them out.

One nice solution, used with the Altec Lansing True EVO Wireless Earbuds, is to provide a carrying case to store the earbuds and keep them safe.

Altec Lansing also builds battery into the case, so whenever you remove the earbuds they can be immediately recharging in the case.

The True EVO earbuds have a 4 hour battery life, plus can add 4 additional charges from the case.

Then, as an extra bonus, the case can be charged not only by USB, but also through Qi wireless charging. So just place the case on a Qi charger and it also can recharge with no wires.

The other issue with earbuds is the hostile environment that builds up in your ears when you move around and exercise. The True EVO earbuds are designed to be rugged, especially for sports, and are sweatproof and waterproof.

These also provide double-tap access to the Apple Siri or Hey Google voice assistant, and have a 30 feet wireless range.

To minimize your audio equipment, the Altec Lansing True EVO Wireless Earbuds are available for around $99.

Altec Lansing Portable Bluetooth Wireless Speakers

The excitement in audio recently has been in Wi-Fi speakers for smart homes that can be coordinated and controlled by voice commands. But Bluetooth wireless speakers still are very useful -- especially as a personal, easily-portable speakers that can move from room to room, indoors to outdoors, and come along when you are on the go.

This year's focus for Bluetooth speakers is on making them more rugged -- and not only waterproof, but even able to float. The Altec Lansing line of portable speakers also integrate with voice assistants, and some support extended range for the Bluetooth connection -- up to 100 feet.

For personal use, at your desk or in a hotel room, you can start with a mini speaker like the Altec Lansing Baby Boom, a compact, rugged speaker that is smaller than your hand (around 4 x 2 x 1 inches, and 1/4 pound).

The Baby Boom puts out impressive sound for its size, with two 1" drivers with neodymium magnets.

You can pair two of them as stereo speakers, with a 30 foot wireless range. And it works as a hands-free speakerphone for your smartphone. It also has a 3.5 mm auxiliary input to play from other wired sources.

The Altec Lansing Baby Boom has 6 hours of battery life, is waterproof and floats, and is available for around $29. It even has a carabineer clip to attach to your backpack.

Or step up to a slightly larger speaker like the Altec Lansing Mini LifeJacket Jolt, a compact speaker with serious bass (around 6 1/4 x 2 1/2 x 2 1/4 inches).

This is not quite pocket size, with dual 1.5" neodymium drives / woofers plus two 40mm passive radiators, has a 100 foot wireless range, and you can pair up to 50 speakers at once for a big house party.

It also has a dedicated button to activate Apple Siri or Google Assistant, and is waterproof and floats.

The Altec Lansing Mini LifeJacket Jolt has 16 hours of battery life, and has a USB port so it also can be used as a charger for your smartphone. It's available for around $79.

Then the Altec Lansing Versa line of smart speakers pairs and plays over both Bluetooth (for on the go) and Wi-Fi (for at home). Use the Altec Lansing VersA Navigator app for Wi-Fi setup and to bridge to Amazon Alexa for tap-to-talk voice control.

The smaller Altec Lansing VersA 2 Go model is still relatively compact (around 4 x 4 x 2 inches).

It delivers impressive sound with a 1.75" woofer and 2" passive radiator, with a 100 foot wireless range.

Altec Lansing VersA 2 Go is waterproof, has 8 hours of battery life, and is available for around $69., It also has a carabineer clip.

So in the range of $29 to $79 you can have a rugged Bluetooth speaker that syncs cleanly with your smartphone to deliver improved sound and relay voice commands. They talk to you to confirm power on and Bluetooth pairing status. These also all have a two-sided design, to fill a space better by pumping out sound in all directions.

TP-Link - Smart Home Power and Bulbs

Smart Home companies like TP-Link make products that you can use to control and manage your home, including the TP-Link Kasa Smart line of Wi-Fi plugs, light bulbs, light switches, and smart camera -- plus the networking routers and Wi-Fi extenders to use to communicate with these devices.

These smart devices can be controlled and scheduled from the Kasa app, or by voice from digital assistants like Amazon Alexa and Google Assistant. (See Holiday 2017 for more on Smart Home devices.)

While this year's crop of smart home devices does not feature exotic new technology, it is another striking example of how technology continues to advance with better, smaller, and cheaper products.

For example, the TP-Link Kasa Smart Plugs allow you to remotely control anything that you plug into them, for example to turn the holiday decorations on and off.

The new TP-Link Kasa Smart Plug Mini (HS105) has also dropped in price, now at around $26 compared to $34 last year.

But the real fun is the new TP-Link Kasa Smart Wi-Fi Power Strip (HS300), which crams 6 smart outlets plus 3 USB charging ports onto a power strip -- for only around $79.

Yes, the power strip is a tad long at 14.17 x 2.49 x 1.48 inches and 1.55 pounds, but you get full control of the outlets -- you can power them on and off independently, or all together as a group.

The Kasa Smart Power Strip also monitors the energy usage of the connected devices, and provides surge protection.

Similarly, this year's TP-Link Kasa Smart Light Bulb line includes new dimmable (adjust brightness), Tunable (soft to bright light), and Multicolor bulbs that have improved in all three of these ways.

The new TP-Link Kasa Multicolor Smart Light Bulb (KL130) is dimmable, tunable, and can adjust the color (2500K - 9000K). The big difference is the further compaction of the Wi-Fi and color tuning electronics, thinning the shape so that it's even closer to the volume of a traditional light bulb.

Kasa Multicolor Smart Light Bulb is available for around $39, compared to $42 for the previous model last year.

And it's smaller -- 4.65 x 2.36 inches vs 5.14 x 2.56 inches (118 x 60 mm vs 130.5 x 65 mm) -- and lighter -- 0.3 pounds vs 0.4 pounds (139 g vs 180 g).

So it's fun to see the improvement in these products in just a year, and to control devices in your home to make them smart. For example, think about what you can do with holiday decorations -- displaying colors and controlling other decorations directly, or by setting up a daily schedule of changes over time.

Ventev - Wireless Charging

Wireless charging sounds like such a great idea -- No more profusion of cables, and no more confusing plugs that always seem to be the wrong type or positioned upside down. Instead, just put your device down on a mat and it magically charges.

Someday, these chargers will be built in to our lives -- bedside tables at home, desks at the office, and side tables in hotels. However, this promise has been hampered for years by confusion in the market between different competing standards.

But now the industry has coalesced behind the Qi standard, from the Wireless Power Consortium (WPC). (Think of qi as meaning "energy flow" from the Chinese.)

Qi wireless charging has the support of major manufacturers, including Apple, ASUS, Canon, Dell, Google, Lenovo, LG, Panasonic, Samsung, and Sony, and is built in to Apple's iPhone 8, iPhone 8 plus, and iPhone X.

These products use inductive wireless power transfer, which requires close contact (basically directly touching), and typically also requires aligning the device with the coils in the charging plate.

A second technology, resonant wireless charging, offers a more relaxed distance (up to 45 mm / 1.7 in), which is especially interesting for devices like laptops and wearables. This is under development by the WPC, as well as the new AirFuel Alliance, which was formed from several competing groups including the Power Matters Alliance (PMA), which has been used in some products.

Wireless chargers are typically designed as mats or pucks that you can lay a smartphone down on. Of course, you do then need to plug in the charging plate.

Ventev also offers the Ventev Wireless Chargestand for smartphones, in addition to its traditional batteries and chargers (see previous post).

The Wireless Chargestand is a combination desktop charger and smartphone stand. The wireless charging puck is removable, so you can use it (and the stand) independently.

The stand and its aluminum frame are adjustable, for two viewing angles, for different positions (portrait, landscape, or flat on table), and for optimal charging centered on the back of the smartphone.

The Chargestand provides 15W of power, so you can use the smartphone while it is charging. And it supports fast wireless charging, so the smartphone can charge 50% in one hour. It also has built-in protection from short circuit, overcharge, overdischarge, and overcurrent.

Interestingly, the Chargestand supports both the Qi and PMA wireless charging standards, so can work with a variety of older and newer devices.

The Ventev Wireless Chargestand is available for around $59. It's a nice flexible design, supporting multiple uses (flat and as a stand), and multiple devices (Qi and PMA).

Ventev Portable Batteries

Even with continued technological advances, our portable devices still require power, which becomes more of a problem when we're on the go and bring along more and more such thirsty devices.

Ventev offers a nice range of power accessories, including portable batteries, wall chargers, and car ports -- with its trademark matte light grey finish with orange accents.

For example, the Ventev Powercell 6010+ Backup Battery is a combination external battery pack and wall charger. It has everything you need built in - folding AC prongs to plug in to the wall to recharge the battery, and a built-in cable (Apple Lightning or USB type C) to feed your devices.

The 6000 mAh battery has 12W total output, so it can charge a tablet, or two smartphones at once (using the built-in cable and the additional USB port). It recharges in 4 to 5 hours

But it still is relatively small and light -- shirt-pocket size at 5.2 x 0.7 x 2.7 inches, and 6.7 ounces.

The Ventev Powercell 6010+ is available for around $49 in two versions, with Apple Lightning or USB type C cable.

Another option is a combination desktop charging stand and backup battery like the Ventev Chargestand 3000c Backup Battery/Stand.

This is a lightweight combination portable desktop charger, stand, and battery. It's around 3 1/8 x 2 1/4 x 1 1/8 inches.

As a stand, it pops open so you can position your smartphone in either portrait or landscape orientations.

As a desktop charger, you can dock your smartphone with the included flat cable that nests in the stand.

As a portable battery, you can close the stand and unroll the built-in cable to charge your smartphone on the go. The 3000mAh battery charges one smartphone, and recharges in 3 to 4 hours.

The Ventev Chargestand 3000c is available for around $49 in three versions, with built-in microUSB, USB-C, or Apple Lightning cable.

Western Digital Portable Wireless Drives

The Western Digital My Passport Ultra hard-disk drive and My Passport SSD drive provide highly portable and rather inexpensive storage that you just cable up to your computer (see previous post).

Or you can go wireless with the Western Digital My Passport Wireless drives that also can communicate over Wi-Fi, so you can access them from multiple devices, including computers, smartphones and tablets, and even for direct FTP transfers from a camera.

Plus they have a built-in SD card reader, and can serve as an external battery power source for your other portable devices.

The WD My Passport Wireless Pro is a wireless hard-disk drive, SD card reader, and powerbank. It's about 5 x 5 inches square and 0.9 inches thick, and weighs around 15 1/2 ounces.

It's available with 1 TB of storage for around $149, 2 TB for $139, 3 TB for $199, and 4 TB for $189.

The WD My Passport Wireless SSD provides the same functions with a solid-state drive. It's especially durable with the SSD electronics and a protective bumper, so it's protected from shock, vibrations, and drops of up to 1 meter, even in operation.

It's available with 256 GB of storage for around $229, 500 GB for $299, 1 TB for $499, and 2 TB for $799.

For the fastest wireless connection, you connect directly to the drive as its own Wi-Fi hotspot. Or you can connect your devices and the drive to your local Wi-Fi connection, which then allows you to access the Internet as well -- although with lower transfer rates since the connection is indirect and shared.

You then can use the drive's Dashboard Web interface to set up the drive and transfer files. Or you can access the drive using the WD My Cloud app for iOS or Android. The drives also include DLNA and Plex media servers to stream to smart TVs and other devices.

You also can use the built-in SD card reader to share files from cameras or other devices, or to back up the contents of SD cards.

Plus, for wired connections, these drives have both a USB 3.0 port and a USB 2.0 port. With these, you can connect directly to a computer as a standard external drive, plug in another USB device and share its contents wirelessly, or power another portable battery from the built-in battery. The battery provides 10 hours of continuous use, whether recording files or streaming media.

These WD My Passport Wireless drives are multi-talented wireless hubs -- both to share from the built-in disk, SD cards, another USB drive, and even wireless cameras over FTP -- and to share to multiple other devices including laptops, smartphones, and tablets.

That's a lot of features, but wonderfully flexible and useful when you need them, whether assembling files and media from multiple sources in the field, or providing access to common files among several people and systems.
