On Becoming a Maker Dad: Tinkering with a 9-year old & LED Strips Nathan Christiansen
“Dad, what’s a circuit?” Coming from my nine-year old daughter every question is perilous, but this one was precious because it touches something I love, and even more rare it is a question I can answer. My talking about circuits quickly turned into showing about circuits; in a few minutes we were digging through the electrics bin in the garage for parts. We found some three-color LED strips (leftover from a previous Mouser purchase) and away we ran.

See the History of RF Engineering in this Large Old Magazine Archive Barry Manz
On Oct. 31, 2013, Broadcast Engineering, a publication I’ve been reading for 20 years, closed its doors. The company chose to throw in the towel rather than retreating to “digital only”, typically the last gasp before the grave. I learned this not from the company itself but from my colleague Lynnette Reese who sent me a link to back issues (of which there are 340) on a site her Ham dad found: americanradiohistory.com. She blogged about it too, but I had to take a description of this site a step further, as it is absolutely every bit the “gem” she described. It’s also hardly a secret as Alexa ranks it 147,429 in the U.S., placing it above most trade journal sites, but it was a revelation to me.

You’ve Got Mail: Branching Out Beyond The Arduino, Part 2 Mike Parks
We’re going to jump right in with this blog post. If you haven’t done so already I highly encourage you to read this article about an automated mailbox delivery project I recently completed. Also check out the first blog post in this series that discussed some key lessons learned, including the importance of reading the manual and some thoughts on open source software

Thinking About Learning in a New Way Caroline Storm Westenhover
What is that in-between place between boring and floundering? It’s that place where you feel challenged, but not overwhelmed. For me Modern Physics is that place. I enjoy going to class. I like reading the material and doing the homework. I find myself thinking about the math and therefore thinking about physics in general.

You’ve Got Mail: Branching Out Beyond The Arduino, Part I Mike Parks
In a recent article published last month titled Solar Energy Harvesting Project to Power a Remote MSP430 with 2.4GHz Notification, we tried to inspire designers and makers that have limited experience outside of the Arduino microcontroller platform to explore different platforms typically used by more seasoned design engineers.

Going Griswold for the Holidays Erik Smith
If National Lampoon’s Christmas Vacation has taught me anything, it’s to not hold back on my insane desire to light up the house one Christmas, regardless of how many lumens get blasted into the neighborhood. A “Griswold” display used to be placing as many lights as your fuses could handle onto your house. As of late, it’s become more creative. A LOT more creative.

Outta the way Ferrari. 0 to 1000mph in X seconds. David Fambrough
Don’t know about you, but I’m always exploring the far reaches of cyberspace to find something out there that speaks to me. Something that makes me wonder and reply, “no freaking way.”

Triodes are Still a Hot Item in Audio Lynnette Reese
Every now and then you come across a real gem on the internet. My father was a Coast Guard electronics technician early in his career, and it’s interesting to be able to talk with my dad about electronics stuff. This morning he sent me a link to a site with old Broadcasting and Audio Engineering magazines going back to the 1920s. I look at this ad in Figure 1 from Audio Engineering of June 1949 and have to ask: “What is a Triode?” Triodes are vacuum tubes, boys and girls. Isn’t it interesting that audiophile “purists” today would buy these very tubes for a glowing, more thrilling audio experience? Admittedly, tubes are more interesting to look at than solid state.

The Rebel in the Electric Car Lynnette Reese
I had a very interesting conversation with a power electronics specialist regarding charging for electric vehicles. Let me elaborate: Charging for road taxes for electric vehicles. Those rich guys who can afford the Tesla are not paying road taxes like the rest of us. (I will call “us” The Combustibles Group.) And neither are the Leaf folks, either. The incentive in the U.S. is still a $7,500 tax credit for buying an electric vehicle. A tax credit here means that you figure up your bill to Uncle Sam on April 15 and then subtract $7,500 from what you owe.

A Conversation on High Operating Voltages Kelly Casey
Like most professions, engineering has developed a language of its own. This is needed to convey very specific and precise information. Fuse design engineers, for instance, make a very clear distinction between an overload condition and a short-circuit condition. (Overloads are in the range of ~200% of the fuse's rating while short-circuits are 10X or more.)
