Over the past few week my team and I have been working on a set of self-paced labs for building Internet connected Things using Arduino. Last night we got together with 150 of our closest DevIntersection/anglebrackets friends and had a great hack event. Lots of developers got their first exposure to Arduino and to building […]
In this lesson you will combine the ideas that you learned in the previous lessons (here and here) to make a LED change its brightness based on the level of light available – essentially a nightlight. You will learn a couple of new methods you can use and we’ll discuss Pulse Wave Modulation (PWM) briefly. […]
In this lesson you will use two resistors – a static resistor and a variable resistor – to create a voltage divider that enables you to effectively understand the intensity of light detected by the photoresistor – essentially a light meter. In the previous lesson you learned how to send OUTPUT and in this lesson […]
I just posted my first lesson to Instructables.com. This is the first in a series of IoT lessons using the Arduino Yun. The lessons will build from this ‘Hello, World!’ lesson to fully connected devices leveraging Cloud IoT services, web and mobile apps, and backend analytics and machine learning. Check out lesson #1 here.
Recently I was rebuilding my multi-rotor (x-type quad) and switching from the CC3D flight controller (which I love) to the APM 2.6 (ReadyToFlyer from Ready to Flyer Quads) flight controller. I wanted to add GPS and compass to enable fully autonomous flight, so I added the uBlox 6M GPS W/ Mounting backplane and compass module. […]
Last week, while on vacation in San Diego, I took a golf lesson from a veteran golf pro, Bob Madsen. For the record, I am not a good golfer. While I have swung a club at a white ball for many years, I have failed to improve during this time due to lack of dedicating […]
Earlier this week we, the Developer Division at Microsoft,release a series of short videos telling the story of how we made the transformation from our old waterfallian ways to a scaled agile way of working. Here is where you can find all of the videos. This is the story of a division of 3,000+ engineers […]
In the first 45-minutes the market was open the faulty software deployment sent millions of child orders into the market resulting in 4 million transactions against 154 stocks for more than 397 million shares. In laymen’s terms, Knight Capital Group realized a $460 million loss in 45-minutes and went from being the largest trader in US equities and a major market maker in the NYSE and NASDAQ to bankrupt.
Most of my life I’ve been a fan of strategy games – Risk®, Age of Empires, even Checkers. These games all demand that the player has a solid strategy, or they will likely be defeated by their opponent. Anyone playing without a strategy is just executing random actions based on feeling or intuition (or luck), […]
For any product group or organization to be successful they must know where they are going and how they are going to get there. I’m not talking about the product backlog or the release schedule – I am talking about something more abstract than that. Within the DNA of any product group or organization there […]
