Measuring a Steam Engine's Speed with Arduino

Steam engines were integral to the industrial revolution, and steam power— in a different form—provide electrical power to a vast number of people. You may have some vague idea that a steam engine pistons push a wheel in a reciprocating motion, but how does this power source actually work?

Arduino

As it just so happens, Joop Brokking has obtained one so small that it’s powered by a small beeswax candle, and shows us how it works in the video below. The boiler is first filled with water, then the candle is lit. After a few minutes, the water gets hot enough to bubble up and push the piston over and over after starting the flywheel. The trick here is that as the piston moves, it intermittently aligns with a port that pushes steam in, then a second port that allows it to exhaust at the top. When combined with a flywheel, the system clicks along nicely at around 1850 RPM… But how does Brokking know its speed?

Arduino

The answer comes at around 5:15 in the video, where he measures it with an Arduino, LED, and potentiometer. He simply adjusts the light to flash at the correct speed with the input potentiometer, eventually making it appear nearly still via a stroboscopic effect. This is then read out of the serial port, giving a convenient way to measure any sort of reciprocating motion.

For another pointless-but-awesome device, check out the solenoid boxer engine model that we covered earlier!

10 Must-have Skills for Data Engineering Jobs

Big data skills are crucial to land up data engineering job roles. From designing, creating, building, and maintaining data pipelines to collating raw data from various sources and ensuring performance optimization, data engineering professionals carry a plethora of tasks. They are expected to know about big data frameworks, databases, building data infrastructure, containers, and more. It is also important that they have hands-on exposure to tools such as Scala, Hadoop, HPCC, Storm, Cloudera, Rapidminer, SPSS, SAS, Excel, R, Python, Docker, Kubernetes, MapReduce, Pig, and to name a few.

Here, we list some of the important skills that one should possess to build a successful career in big data.

1. Database Tools
2. Data Transformation Tools
3. Data Ingestion Tools
4. Data Mining Tools

What Are Google Compute Engine ? - Explained

The Google computer engine exchanges a large number of scalable virtual machines to serve as clusters used for that purpose. GCE can be managed through a RESTful API, command line interface, or web console. The computing engine is serviced for a minimum of 10-minutes per use. There is no up or front fee or time commitment. GCE competes with Amazon’s Elastic Compute Cloud (EC2) and Microsoft Azure.

Top 10 Companies Hiring Data Engineering Professionals

Analytics Insight has listed top 10 companies hiring data engineering professionals with a decent salary

Over the past few years, the usage of data has exploded drastically. More people, organizations, businesses, etc. are availing data as part of their routine mechanism. Earlier, people focused more on useful insights and analysis, but now, they have come to the sense that managing data also needs equal importance. As a result, the role of data engineer has ballooned in the technology sector. Data engineering is the aspect of data science that focuses on practical applications of data collection and analysis. Data engineers are responsible for finding trends in datasets and developing algorithms to help make raw data more useful to the enterprise. The Dice 2020 Tech Job Report labeled data engineering as the fastest-growing job of 2019, with a 50% year-over-year growth in the number of openings. According to Dataquest, data engineers performs three main roles namely generalist (found in small teams or small companies), pipeline-centric (found in midsize companies) and database-centric (works in large organizations). Analytics Insight has figured top 10 companies hiring data engineering professionals with decent salary.

Shreemoy's stint in Big Data being a Mechanical Engineer

Shreemoy Nayak is an alumnus of UpGrad and BITS Pialni Big Data Engineering program.

I am a mechanical engineer currently working as a project engineer. My job is to execute the projects at the site and deliver them on time. Though my job doesn’t involve data analysis at the scale of banking or FMCG industry, it demands a certain level of awareness for planning and executing a project. During my 2-year experience, I’ve come across situations, more often than not, when things don’t go as planned and the engineer-in-charge needs to make informed decisions to complete the job in time while making sure the expenditure doesn’t exceed the sanction.

In these cases, a sound knowledge of exploiting the data, both financial and otherwise, from previous and ongoing projects those are similar to the current project, comes in handy. In today’s world data-driven decision making has taken the front seat and Big Data is going to be the next big thing.

With a sound knowledge of statistics, I searched for online courses related to data analysis and came across this PG Program in Big Data Engineering offered by BITS Pilani in association with UpGrad on Facebook. Initially, I was apprehensive. But 7 months into this program and I am sure I’ve made the right decision.
