Canon 24mm 2.8 Lens Hack for Sigma MC-11 Adapter

On an APS-C camera like the 24mm is around a 38mm on a full-frame. 35mm is the closest to the focal composition of the human eye and the 24mm ended up being my favorite lens.

The DJI Spark: Why I Held Off Getting into 4K

The DJI Spark: Why I Held Off Getting into 4K

Recently I picked up a quadcopter by DJI, called the Spark. I purchased this model over the DJI Mavic Pro for a number of reasons; price, size, and image quality. In my post I offer a couple of smaller quadcopter models I used to practice.

     There was a video on WIRED I watched about holding your breath under water. The video is here: Why It's Almost Impossible to Hold Your Breathe for 24 Minutes

     The video inspired me to share my stories and experiences with "Breath Holding". I like to think I'm uniquely qualified in this department called "breathing" because I'm an asthmatic and Leukemia Survivor. My parents would tell you, in my early years, I was in the hospital more than I was home. My Mom always kept me close and inside which probably propelled my creativity and my lust for knowledge. Despite these facts, later on in life, I became a very active kid and athletic. She was always hanging on to me trying to keep me from danger, while I ran towards it. We couldn't afford for me to play Little League Sports, so I played outside a lot.  When it got cold in the winter and I would get sick, things got really scary for me. One of my most memorable experiences was when I was about 12 years old. I had gotten sick and I was desperately trying to breathe in the backseat of our car as my Father sped us to the hospital. It was a harrowing experience, as I was taking super deep breaths and I was probably getting an 1/6th of the air I wanted/needed. It was exhausting too.

   It was the scariest time I could remember.  While laying on the cold leather seat, I wasted no energy and was laser-focused on just getting air into my lungs. When we arrived, they immediately gave me a Nebulizer treatment. Back then, the Nebulizer was a really big machine, nothing like the mobile units today. I'm forever thankful my parents had great Health Care Coverage for us. I remember being smaller and having attacks, but this one changed the way I thought about it. There was a sense of urgency and purpose in trying to beat my ailment or at the very least building up a resistance. Then I saw a movie. There was a movie that came out in 1988 with Jean Reno, Rosana Arquette and it was Directed by Luc Besson (La Femme Nikita, Leon: The Professional, The Fifth Element). The film was called The Big Blue and to me it was amazing. It was a movie about two childhood friends who became rivals in "Freediving". 

I was fortunate my father loved watching foreign movies and would always bring home something different. It was filmed in English, but I think it got here by way of Italy or France; I remember there being subtitles on the film. You might be able to find it on Netflix, but if you can't, somebody uploaded the entire movie in a Drive-In Theater frame on Youtube: ) If you're a Cinefile, you'll appreciate watching one of Luc Besson's early endeavors and recognizing his signature style. 

    Besson had learned how to Scuba Dive early in his youth, which would explain why one of his first big features was about diving. The way he presented the character was fantastic. They were underground celebrities because of their superhuman skill. They were freaks of nature already, but they hyper-developed their breath holding into superpowers. I was amazed a human could hold their breath that long.  I became obsessed. I immediately started researching how to get a longer breathe hold. I was already practicing how to slow down my heart rate so my pulse would be undetectable (saw it in an 80's Ninja movie).  We had a community pool where my friends and I would spend most of our summer days. For weeks, you could find me in the deep end holding my self under water near a ladder. I was already a good swimmer, athletic, competitive, and good at research. Now I was learning how to discipline my breathing and all the associated thought processes. 

      My Mom had always made sure we had Library Cards and would take us there frequently.  So I read, practiced and then practiced some more. Just like was stated in the Wired video, there are ways to trick your body into doing what you need it to. I had no idea about the physiological science behind the techniques, I was interested in the mechanics and increasing my "breathhold" to aid my fight against asthma. I tried to move as little as possible and to help me slow time I thought about making a hamburger. For reals. That's how I started achieving breathe holds up to 2:45 and 3 minutes. I would think about the entire process of making and cooking a hamburger; from getting the meat from the freezer-all the way to getting the burger on the bun.  After that experimental summer, I had developed ways to control my breathing and expand my breathe-hold. The techniques helped me so much, I was able to play as a Defenesive Back on our Championship Highschool Football Team and become an Highschool All-Star in Lacrosse. 

     Which brings me to Jiu-Jitsu. One of the first things I ever learned in Jiu Jitsu, was how to breathe. I had always been in fights and found myself wrestling with wrestlers. So much so, that I often get accused of being a wrestler when I roll with others on the mats.  There wasn't a move I can remember learning first outside of breathing, because before I stepped into the gym my buddy talked to me about it.  I was lucky enough he gave me a technique on how to breathe while doing Brazilian Jiu Jitsu. He gave me that gift and I ran with it. Coupled with my knowledge of breathing techniques I learned in my youth, it was the first piece of my "Jits" game. My utilization of "air" helped my "gas". It allowed me energy and time to learn how to efficiently escape when I would become "uncomfortable". It is so important. So much so, you can see it evidenced here by Gracie Jiu Jitsu Grandmaster Rickson Gracie: 

Grandmaster Rickson Gracie explaining the components of his style and how breathing is one of the most important.

     After class one day, I was speaking with my Gracie Jiu Jitsu Instructor as we mopped the mats. He knew I had a Garmin VivoSmart + and asked me what I used it for. I explained to him how I can track my steps, running, and bicycling, but mostly I try to keep track of my heart rate. Then I explained how I used to read Ninja books and then I told him about the hamburger. He looked at me like I was ridiculous. You only have so many moments with people and sometimes you aren't able to have in-depth convos to explain. Especially when you have a whole blog post like this, dancing in your head, and on the tip of your tongue. You don't get the time to talk to people in depth about your experiences and first-hand knowledge. All that comes out is, "hamburger." Having rolled with him, he is the greatest "energy vampire" I ever encountered. His technique was amazing, but I was fixated on how he made me expend energy; how he disrupted my breathing. He didn't allow me to make a "burger."

     This was an opportunity to make sense of what I learned, how I learned it, and why I learned it. Whether you have asthma, a walker, runner, cyclist, swimmer, or a cancer fighter/survivor-learning breathing techniques will help you for the rest of your life.

A smart watch and GPS with Android 2.0.

The Casio Pro Trek Smart (WSD-F20)

The Casio Pro Trek Smart (WSD-F20)

     Personally I own a Casio ProTrek Tough Solar watch and that thing is really tough. It gives me altitude, barometric pressure, and has an digital compass. It also has all your regular watch functions (time, alarms, stopwatch, and timer). It was also doesn't need a battery.

Here's a really great review on youtube from Phone Arena. 

-Digital Ninja ® out. 



     Mark Cuban invested recently in a company called Radical Transport founded by  Nick Fragnito & EJ Williams.

Don't call it a hoverboard!

Don't call it a hoverboard!

The two founders had previously developed powertrain controls for the Tesla Model S. They re-imagined the "hoverboard" and created the forward thinking "Moov" design. There are some major differences versus the popular battery burning & exploding cheaper Chinese import versions. They are careful not to call the Moov a "hoverboard", which is great because these are not Marty McFly's "hoverboard" like in the Back to the Future films.

A couple things immediately jump out with the MOOV:

1. The board is a single piece of aluminum; meaning the board doesn't have two separate independent foot pedals. You turn using their TORSION TURN TECHNOLOGY.

2. An almost all aluminum structure makes theirs significantly stronger and tougher than other plastic models of similar design. 

3. The noticeable larger wheel size allows for smoother riding on various surface types. 

4. Batteries that don't catch on fire or explode. The Radical Transport team has rigorously tested their battery/power system and are UL certified.

5. Rider adjustability. There is an app that can adjust the rider's skill level and the sensitivity of the controls. 

The MOOV is a significant departure from the entertainment toys of similar design. 

The MOOV is a significant departure from the entertainment toys of similar design. 


Here is a little more information explaining some of the boards features.


TORSION TURN TECHNOLOGY: Harnessing a unibody design with integrated sensors, MOOV responds to your body's natural sense of balance, increasing rider stability and improving handling.

INTELLIGENT SENSORS: By strategically utilizing integrated sensors, we gain more effective rider input than traditional footpad controls.

PROGRAMMABLE RIDING MODES: With programmable riding modes, riders can safely master the board before operating at higher speeds. Over the life of the board, the ride continues to suit the rider.

INTERCHANGEABLE DECKS (one of their best ideas!): Inspired by skate and snowboard culture, MOOV’s decks can be customized to suit your unique style. The interchangeable decks are secured with powerful magnets for a fast and painless swap.


They are definitely making sure we know the boards are quality designed, built, tested, and certified right here in Dallas, Texas USA. The re-engineering of the physics, surrounding technology, and ability to customize the Moov separates the device significantly from their toy counterparts. 


Here are some of their more detailed specifications.



Machine Grade Aluminum
Cast from the highest grade aluminum

Durable Coatings
Durable powder coated finish

Precise Details
Precision machined for highest level of precision and accuracy

Rigid Ride Platform
Stable ride platform for advanced control and dynamic ride

Powerful LEDs illuminate the rider path, communicate riding profile, vehicle status and Disco Mode 

Sealed Internal Core
Weather resistant seals to prevent ingress

Interchangeable Magnetic Decks



36V 9" Diameter

2 × 350W Hub Motor

Max Ascent Angle


Nominal Capacity / Voltage
6600mAh / 37V

Charging Time

~12 miles

Having only experience on a regular hoverboard, its difficult to compare it to transports like the Segway systems. There are definitely more robust hoverboards on the market now. I like the MOOV, but it has a price tag of $1199+.

If you are interested in purchasing a personal transport, did an extensive set of tests on some other brands depending on your price range. They've made their findings available here:


It would be great if they sent us one to test out (with a Maze Deck?)  Check out the Radical Transport campaign at:
