Electromagnet Superhero Glove

For a class assignment, I needed to make something fabric-based which took an Arduino, some programming, and at least two inputs and outputs. After sketching a few different ideas, I hit on this one: an electromagnetic glove for MagnetoGirl. It sprang to life for me, because magnetism is an invisible force which can seem magical. Also, a superhero can be given life, character, and (the best part) a cool cos ...

Intel Edison Spectrophotometer

This instructable will explain how to build a fairly basic. Of course, this device is nothing compared to a commercial spectrophotometer, but it will allow the builder to understand how such a device works to using it for DIYbio. Know-how The spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. Aspectrophotometer is commonl ...

Internet connected smart humidifier

I worked on creating a Internet connected last week using my open source WiFi relay project as platform. We observe quite dry air at our house, I suspect this is due to the fact that we use fan coils for heating/cooling. Humidity levels at home are usually below the 30% mark, which poses a health risk along with uncomfortably dry air. I’ve found these interesting charts that got me convinced I need to do so ...

AIR HOCKEY TABLE IS A BREEZE TO BUILD

Many of us have considered buying an air hockey table, but are put off by the price. And even if the money is there, those things take up a lot of space. How often are you really going to use it? This DIY air hockey table is the answer. It’s big enough to be fun, but small and light enough to easily stow away in the off-season. At ~$50, it’s a cheap build, provided you have a vacuum cleaner that can switch ...

SENSOR LETS GESTURES AND AN ARDUINO CONTROL THE TUNES

Every time we watch Minority Report we want to make wild hand gestures at our computer — most of them polite. [Rootsaid] wanted to do the same and discovered that the PAJ7620 is an easy way to read hand gestures. The little sensor has a serial interface and can recognize quite a bit of hand waving. To be precise, the device can read nine different motions: up, down, left, right, forward, backward, clockwise ...

Newly Developed Internal Temperature Sensor For Li-ion Battery Enables 5x Faster Charging

Researchers at the University of Warwick in the UK have developed sensors which measure the internal temperature and electrode potential of Lithium batteries. The technology is being developed by the Warwick Manufacturing Group (WMG) as a part of a battery’s normal operation. More intense testings have been done on standard commercially available automotive battery cells. If a battery overheats it becomes a ...

SYNTHETIC SENSORS, All-In-One Smart Home Sensor

In the era of Internet of Things, we wanted most of our home appliances to become smart. But currently, smart devices may cost much more than their offline counterparts and they often do not communicate with each other. Trying to overcome these limitations, A Ph.D student invented a way to turn entire rooms into smart with a single low-cost device called “Synthetic Sensors“. Gierad Laput, is a Ph.D. student ...

PING-PONG BALL MAKES GREAT PID EXAMPLE

It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something like position or temperature. You’ll have a set point — whatever you want the sensor to read — and your job is to adjust the driving thing to make the sensor read the set point value. This seems easy, right? It do ...
