I like to go walking and when I do, I listen to podcasts on my iPhone using earbuds.  Of course, having the cords dangling from your ears and catching on stuff can be quite annoying, so I went in search of something cordless that I would also be able to use as a handsfree headset [...]

I am a bagoholic.  I have two closets filled with bags from waist packs, day bags, shoulder bags to camera backpacks.  Some of them date back a ways...I still have and use both a Roadwired Pod and Podzilla!  I am always on the lookout for that next bag that will hold what I need when [...]

A while back, I reviewed the X1, X2 and X3 UV filters from Breakthrough Photography.  Their slimline cells with ridged edges that make them easier to mount and stack on your lenses have had a permanent place on my Canon 24-105 f/4L and Canon 16-35 f/4L lenses ever since.  They remain wonderful companions, not getting [...]

Kickstarter has a new project called the Oval Digital HandPan.  It is a percussive instrument that can connect via USB on Android and iOS or Bluetooth MIDI on iOS to the MIDI-compliant music app of your choice to give you an unlimited palette of sound to choose from.  With five sensors per pad, it gives [...]

I recently purchased a 1993 Midwest Micro Elite notebook off of eBay.  It boots to BIOS but that's about it.  I just wanted to own my very first "real" laptop computer again...I sold it off on the comp.sys.laptops USENET group back around 1995 and kind of regretted it ever since.  It has a serial port, [...]

Technology has come a long, long way in the last 10 years but battery technology has lagged behind.  There are limitations to electrochemistry that nanoscale carbon substrates can help boost but until that day we have become accustomed to carrying around spare battery packs for our devices.  With more and more devices sealing their batteries [...]

When I was a kid, I played Dungeons and Dragons.  My favorite character was a cleric named Becket.  Original, I know.  One of the spells I found most useful was Continual Light.  This created a very strong light source wherever the spell was cast.  I figured out a way to overcome the inherent limitations of [...]

The proliferation of gadgets without keyboards has been explosive over the last few years, as have the options for keyboards to increase productivity.  The Surface and Surface Pro series, the numerous Windows, Android and iOS tablets...all of them call for a keyboard to really maximize productivity with these devices.  Rapoo generously sent us a sample [...]

(Supermodel Priya poses behind the three filters being tested in this review) I love photography.  There isn't a day when I don't have my camera with me, ready to capture something beautiful.  I shoot with a Canon 5D Mark III full-frame dSLR and my workhorse lens is the 24-105 f/4L.  A top-quality lens on a [...]

Whether you like it or not, the selfie is here to stay.  Capturing yourself in the moment is an extremely popular form of self-expression these days.  Heck, I used to turn my film camera around and point it towards myself and take what I hoped would be a usable shot.  Even some new phones are [...]

Synthesizers have been around for a long, long time and many efforts have been made to turn them into expressive, virtuoso performing machines.  Ribbons, X/Y pads and pitch/mod wheels have long been a staple for keyboardists but they all have one glitch...the expressiveness of the note is separated by two hands and two motions that [...]

I love my GPS.  It goes everywhere I go and I depend on it more than I'd really like to admit.  With the advent of the GPS-equipped smartphone, we have the option to use apps like Google Maps and Navigation to stand in for a GPS.  Convergence, right?  Why have two devices when one will [...]

I have owned portable computing devices worn on the hip since I got my HP 200LX in 1994.  I remember going to Circuit City the day the first Palm Pilot was released to grab one. Afterwards I drove up to Woodstock to meet a friend and hike up Overlook Mountain in the Catskills after a [...]

It came in an unassuming box, fitting neatly into my mailbox in a bubble mailer.  I took it out and opened it up and lo!  There was THE gadget I HAD to get my hands on.  Since Maker Faire three years ago I had fallen in love with the Useless Machine.  There are so many [...]

There have been a large number of Bluetooth audio devices reviewed here on The Gadgeteer lately!  Well, they are pretty popular devices.  Especially Bluetooth speakers.  They free you from the tangle of cables, after all!  What we have on offer here for your consideration is the Inateck BP-2001 Portable Bluetooth Speaker.  This review will be [...]

Charging devices is one of the unpleasant and time-consuming tasks that we gadget addicts must endure, thanks to the primitive state of electrochemical energy storage.  While ultracapacitors have not yet set us free from the torturous charging wait time, there are products that purport to make that wait time shorter.  Bench Soft sent us this [...]

I loved watching that footage of the giant meteor that broke up over Chelyabinsk, Russia.  It was caught by dozens of people, from every conceivable angle.  Were they waiting for it to show up?  Heck, no, no one knew it was on its way.  The Russians are big fans of car dash cams to protect [...]

When the Camera Connection Kit first came out for the iPad, it immediately was exploited by musicians worldwide to use the iPad as a MIDI-connected device.  The iPad suddenly became a must-have device for making music.  Apps that mimicked classic synths like the Korg Electribe and MS-20 came out as well as production studio apps [...]

Smartwatches have been a dream of technophiles since the Dick Tracy days.  While they have not yet reached the dream of the standalone phone, what they can do while partnered with a smartphone far outstrips anything Tracy's wrist gear aspired to.  Hot on the heels of Samsung's Tizen-powered Gear 2 watch, the Gear Live watch [...]

Technology has come a long way in the last two decades but, sadly, battery technology has barely kept pace.  We use the same electrochemical principles that Allesandro Volta used when he invented the voltaic pile in the 1800's.  We have found better materials and have improved on the design to squeeze every available electron from [...]

Canon's EF 16-35 f/2.8 L II is a very popular lens, particularly for landscape and architectural photography.  It has remained out of the reach of many enthusiast photographers due to its very high price  ($1700, but at the time of this writing there is a $200 mail-in rebate).  The lens is also not image stabilized, [...]

I love photography.  There is seldom a moment when I am not at work and there isn't a camera in my hand.  Like all photographers, I go through camera bags like crazy.  What works for one application somehow doesn't seem to work for another.  I have used such camera bags as the Billingham Hadley Pro [...]

I like pens.  Beats the heck out of carving pictograms into rock.  You know, take a harder rock and scrape it against the softer rock.  The process is tedious but the results do last a long time.  Pens make it a lot easier and, as everyone knows, they are mightier than swords.  If only Ned [...]

I am a mild-mannered chemistry teacher most of the year but for two weeks out of every year I visit the Great Plains in search of the most intense weather Mother Nature can throw at us.  I have been bringing a Kestrel 4000 weather meter with me to measure the temperature, dewpoint and wind speed [...]

There's a great thing about being a teacher...being entrusted with a large number of keys.  Keys to my classrooms, to the different cabinets in the classroom, my desk, my filing cabinets, cabinets in different rooms, the bathroom and the goggle cabinet.  I teach chemistry and there are a large number of cabinets I need to [...]
