I have two CBs, good buddy! If my eight year old self had to choose, my CB handle would be “Hot Rod.” As a kid I grew up watching The Dukes of Hazzard and playing with Matchbox and Hot Wheels cars, so I chose this nickname. As far as I can remember, I am the only person that ever called me by my nickname.

Today my handle might be “B1tj0ckey,” as I’ve been called that (fondly?) by project management types due to my FPGA and digital hardware design role. Or I might go by “Kabijj,” in reference to a comedy sci-fi movie that Tori Spelling starred in but refused to be credited.

Like Yoda talk, I would! Vader rasp difficult, it would be. Asthma bad enough, it is.

3D Printers in STEM Education

Twice as many 3D printers were on display at the International Consumer Electronics Show last month compared to the event in 2014. The emerging technology fascinates with what it can already do—from printing food, cars, and even body parts. If you think that techies are the only ones using this technology, think again. We here […]

Autism Awareness – “Light It Up Blue” Project

Today, April 2nd, is World Autism Awareness Day, and April has been designated Autism Awareness month. To kick off the month, Autism Speaks encourages individuals and businesses to “Light It Up Blue” for Autism awareness. Autism spectrum disorder (ASD) covers many complex brain developmental disorders. There are many individuals that fall under the umbrella of […]

Lunch Break: Frisbee

I really enjoy playing Frisbee. It is a sport that adapts well to age, ability, number of participants and desired activity level. It is social and can be either serenely calm or exhilaratingly fast-paced. Engineering involves a lot of up-close work, highly detailed and generally behind a desk or lab bench. It is great to get outdoors, go for long distance throws and catches, and spend time with coworkers outside the scope of project requirements. I have found my afternoons to be more productive and focused, albeit at the expense of a few sore muscles the next day, well worth it.

Sealevel Technology Application: Enter the Arena

An arena is a massive facility and is the venue of choice for this example application of Sealevel technology. A control booth on one end of an arena must provide control and obtain status from various equipment on the far side of the arena. Due to the physical separation, the control booth and the equipment panel are on different power sources in the arena. Sealevel’s isolated RS-485 hardware and the SeaPAC R9-8.4 ARM9-based touchscreen computer may be used to provide an end-to-end control solution for this scenario.

Engineering Effective Communication

One of the challenges in engineering is effective communication at each stage of the design process. From initial concept discussions to development of product documentation and technical manuals, expressing complex ideas with clarity, organization, and purposeful language is required.

A Day in the Life of a Sealevel Engineer

For me, one of the draws of engineering at Sealevel is personal involvement in the full product design cycle. Throughout my engineering career I have enjoyed working with a team to bring concepts to reality, and in particular, having visibility and influence over the project as it matures. Engineering at Sealevel is structured, hands-on, and exciting.

Drowning in Email? A Sealevel Engineer Tries Xobni for Outlook

With so much information stored in Outlook, it can sometimes be challenging to find just the email or attachment you need. This is where Xobni can help. Xobni (“inbox” spelled backwards – clever!) is a free Outlook plug-in to search people, email, and attachments instantly. People search not only includes your Outlook contacts, but also includes information found in email signatures, message bodies, and related contact information found from social media sites (including LinkedIn, Facebook, Hoovers, Skype, and Yahoo.) A Xobni search for a person displays not only contact information, but also the email and attachment history. I am especially fond of the historical attachment searching — something I was unable to achieve with the built-in Outlook search.

Getting Things Done: Task Management in Outlook

In the fast-paced world of engineering, there is always something to be done. Typically there are several things to be done, across one or more projects, each with a common goal of designing and delivering quality products. It can be a challenge to capture, prioritize and complete all the tasks at hand in a timely manner without allowing something to fall through the cracks. Then a good friend recommended I read “Getting Things Done: The Art of Stress-Free Productivity” by David Allen. This book changed the way I capture, prioritize, status, and execute tasks.
