This is a submission about an Arduino in Action from Memphis, Tennnessee by Guy Cobb. Here is what he posted: Hello from Memphis, Tennessee. I wanted to send all of you at the Arduino headquarters this photo of my office with my Arduino “wallpaper” and Arduino earthquake detector. My Arduino project incorporates a Mega, Uno, […]
Dearest Spark friends, Our new hardware is here! In case you’re not feeling the length of this post, here’s the short version: Today we’re launching our new development kit, the Photon! It’s the spiritual sequel to the Spark Core (backwards compatible), and it’s faster, better, and cheaper. You can pre-order it now for $19, and
How Dottie Was Made My trusty Arduino (it’s red, a clone from Sparkfun, and it was on sale for $10) begins this journey to reverse-engineer a flip-dot board. I figure that if I can flip one single dot, using a shift register and a couple of transistors, then all I need to do is replicate
Introducing the Sweet Pea WiFi Shield Have you ever wanted to include WiFi functionality into your Arduino system but been scared away by the shear cost and complexity of it. Not to mention that you normally want to have a few other things in there such as maybe an SD card to be able to

Intel announced its 4004 processor and its chipset through an ad in Electronic News on November 15, 1971, making them the first complete CPU on one chip and the first commercially available microprocessor. The building-block 4004 CPU held 2300 transistors. The microprocessor, the size of a little fingernail, delivered the same computing power as the
I got my first taste of programming with RCX Code and an old Mindstorms RCX 1.0, so maybe it’s nostalgia speaking, but I really admire visual programming languages for their ability to introduce younger folks to programming. With color coded operators, geometrically shaped data types, and no semicolons (!), visual languages have a unique ability
Winter just arrived. The enemy of all batteries. Last year this was the season the auxiliary battery of my T3 VW camper bus bit the dust. This likely happened because I neglected to take care of it over the winter months during which the bus is typically parked in my garage. When the auxiliary battery

Contributed by Publitek European Editors 10/15/2013 Power MOSFETs have become very popular in power electronics designs because of their low capacitance and good high-frequency switching characteristics. They have reached into many applications and are helping to open up new markets in applications, from hybrid and electric vehicles through solar power to extreme-environment exploration. The unifying
