Lithium-ion battery fires: 7 solutions for improved safety

I would feel so much safer on my next flight from Phoenix to Silicon Valley if I knew that there were safeguards in place inside passengers’ smartphones that could prevent fire and explosion from such design decisions like a company packing 10 pounds of Lithium-ion battery into a 5 pound compartment or a smartphone owner buying a lower cost, after-market battery replacing the original battery in their phone ...

Improving Wearables with Flexible and Rechargable Battery

Nowadays, there is a lot of technology that implements wearables in fashion, medicine, worker safety, accessories and much more. Many wearables are coupled with uncomfortable charging cables that are irritating for users to handle, some even have big batteries that make wearables a burden instead of an advantage. Statistics show that people tend to abandon this devices after only 6 months of buying them, an ...

Pressure Sensor of the Future, Today

Pressure sensors are used today in many fields, such as automotive industry, touch screen devices, aviation and biomedical instrumentation, many of these applications require precise and accurate measures. Many times, this can not be achieved because of the limitations of the sensors such as the inability to measure on round surfaces (if they are twisted or wrinkled). To solve this problem a transparent and ...

How to Make a Cheap Arduino MIDI Controller

I'm a huge fan of technology and music, but when I decided to start making my own electronic music, I was discouraged by the high price of MIDI keyboards and controllers. After a lot of tinkering, I saw the opportunity to create my own MIDI keyboard using an Arduino Uno and electric paint, for a fraction of the price compared to existing MIDI devices! In this tutorial, I will explain and show you how to cre ...

FFTs and oscilloscopes: A practical guide

The FFT (Fast Fourier Transform) first appeared when microprocessors entered commercial design in the 1970s. Today almost every oscilloscope from high-priced laboratory models to the lowest-priced hobby models offer FFT analysis. The FFT is a powerful tool, but using it effectively requires some study. I’ll show you how to set up and use the FFT effectively. We’ll skip the technical description of the FFT, ...

Flexipower – A portable, Controllable, Dual Channel Power Supply

Hobbyists, makers, students and pretty much everyone who works with electronics has encountered the same issue, not having a handy power supply to test their projects. Usually, controllable power supplies are big, expensive and for some people difficult to access, and most small power supplies are not controllable. As a result, Roberto Lo Giacco created Flexipower, a small, portable, flexible, and remotely ...

“With U Smart Sole” DIY GPS Embedded Smart Shoe Sole #MITBetterWorld

What do you do when someone is chasing you or you are lost? Cross your fingers? Don't. When you are in trouble, just cross your feet [in a special way] and your location is sent to your family members. Wait there's more! Even the family can get your location just by calling the shoe. When you call the SIM in the shoe, the shoe automatically hangs up the call and reverts back its cur ...

TIBBO – MQTT LIBRARY DEMO

Tibbo created two small programs that illustrate how easy it is to write MQTT-enabled apps in Tibbo BASIC or Tibbo C. To illustrate the use of the MQTT library, we have created two simple Tibbo BASIC applications called “mqtt_publisher” and “mqtt_subscriber”. In our MQTT demo, the publisher device is monitoring three buttons (Tibbits #38). This is done through the keypad (kp.) object. The three buttons on t ...

Chirp Microsystem Made The Smallest And Most Accurate Ultrasonic Time-of-Flight Sensors

Recently Californian startup Chirp Microsystems officially announced two discrete ultrasonic Time-of-Flight (ToF) sensors, the CH-101 and CH-201, with maximum sensing ranges of 1m and 5m, respectively. Both chips have a 3.5×3.5mm package and they are powered by same ASIC or application-specific integrated circuit for signal processing. To achieve different sensing ranges, the Piezoelectric Micro-machined Ul ...

Arduino Solar Tracker (Single or Dual Axis)

https://youtu.be/5KljnLkbgB4 If you’ve installed solar panels on a camper van to provide you with electricity on your camping trip or at home to supplement your electricity usage or take your home completely off grid then you probably know that the panels work the best when they are aligned directly towards the sun. This sounds simple enough, except that the sun moves throughout the day. This is why there a ...
