Arduino LED Matrix

https://youtu.be/Eu9ExmHkkIk https://youtu.be/_srC_gPAEP0 In this short tutorial you will learn how to make an Arduino-powered LED matrix. Unlike several other designs, this one uses a "companion" computer to notify the Arduino which LEDs should be powered. I have provided the code for the Arduino, as well as some Java code for displaying text on the LED matrix (this includes a custom-made 7x5 character fon ...

Physicists design $100 handheld muon detector

At any given moment, the Earth’s atmosphere is showered with high-energy cosmic rays that have been blasted from supernovae and other astrophysical phenomena far beyond the Solar System. When cosmic rays collide with the Earth’s atmosphere, they decay into muons — charged particles that are slightly heavier than an electron. Muons last only fractions of a second, and during their fleeting lifespan they can ...

Panner With Arduino

This project it’s a new time-lapse tripod or panning with two axis that works with an arduino protoboard. Everyone will be able to create their own time-lapse trajectory without need to check it. With the arduino code we’ll can change the value for the movement degrees that we want. Step 1: Bill of Materials - SERVO MOTORS x2 - BUTTONS x2 - ARDUINO BOARD - PROTOBOARD - RESISTORS x2 Step 2: Assembly Step 3: ...

Human Motion Powered Nanotechnology Devices

Michigan State University researchers have came up with a new method for  harvesting energy from human motion using nanotechnology. They designed a low-cost film-like device, a nanogenerator, than can power a LCD display,  keyboard, and some LEDs without any source of electric power, by only using some human touching or pressing. This device called FENG, biocompatible ferroelectret nanogenerator, consists o ...

RoboBee – A Flying Microbot That Can Perform Search And Rescue Missions

Inspired by the biology of a bee, researchers at the Wyss Institute developed RoboBees, man-made microbots that could perform endless roles in agriculture or disaster relief. A RoboBee is about half the size of a paper clip, weighs less than one-tenth of a gram, and flies using materials that contract when an electric pulse is applied. Now, they progressed even further and designed a hybrid RoboBee that can ...

Replacing a dead iPhone battery

About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a “this accessory may not be supported” message appeared on-screen; when I unplugged and re-plugged the iPhone to the charger, it didn’t reappear, so I didn’t think anything more of it … until a half hour later, when the iPhone again alerted me, this time ...

Rotary Encoder with Arduino and Nokia 5110 LCD Tutorial

Introduction Today we will take a look at using a rotary encoder with Arduino and displaying rotation data on the Nokia 5110 LCD display. A rotary encoder is an electro-mechanical device that converts angular position or the rotation of a shaft into analog or digital values. They are mainly of two types, absolute and incremental rotary encoders. The output of the absolute encoders indicates the current posi ...

+/- 1.7g Dual-Axis IMEMS Accelerometer Using ADXL203

The ADXL203 Module  is high precision, low power, complete dual-axis accelerometers with signal conditioned voltage outputs, all on a single, monolithic IC. The ADXL203 measure acceleration with a full-scale range of ±1.7 g, ±5 g, or ±18 g. The ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity).The typical noise floor is 110 μg/√Hz, allowing ...

Radioactivity detection using very simple ionization chamber and a single J-FET transistor

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to measure resistance, in this mode, the multimeter provides a small volt ...
