Turn a pencil drawing into a capacitive sensor for Arduino
Posted on: 08 Aug 2015
Did you know? You can make pencil drawings reactive to touch for use with your projects! It’s really easy, and gives you a lot of flexibility in making interfaces for whatever microcontroller project you’re making. I put this together as part of my UnoJoy project, where we’re using the Arduino as a platform from which […]
The Arduino Synthesizer
Posted on: 07 Aug 2015
The Arduino is able to output sound through a library that has been developed called the Tone Library. By creating an interface and a program that can call certain values to be output to an audio out, the Arduino Synthesizer is a robust tool for making a rudimentary noise machine. It uses granular synthesis techniques […]
Chip technology behind the Bitcoin phenomenon
Posted on: 07 Aug 2015
Ever wondered what the Bitcoin currency means to the electronics industry? Well, there is a Bitcoin electronics ecosystem, and it seems to be growing. An early developer of hardware systems for Bitcoin mining is US-based CoinTerra and it has recently expanded its business by acquiring Europe-based Bitcoin related software company Bits of Proof. Dubbed the […]
Arduino Breathalyzer: Calibrating the MQ-3 Alcohol Sensor
Posted on: 07 Aug 2015
The MQ-3 is an alcohol gas sensor that is available for about $5 from Sparkfun, Seeed Studio, and others. It’s easy to use and has sparked the imagination of anyone who has dreamed of building their own breathalyzer device for measuring the amount of alcohol in the human body. I got an MQ-3 sensor a […]
Arduino Laser Trip Wire
Posted on: 07 Aug 2015
For this dandy little project you’ll need: Arduino – I’m using an Arduino Uno a 3 x 4 keypad a 16 x 2 LCD screen a laser module/sensor a light dependent resistor (LDR) a buzzer 3 x 220 ohm resistors 1 x 10K resistor 1 x 10k potentiometer (optional, it’s to adjust the LCD screen […]
SD Card Data Readable Anywhere
Posted on: 07 Aug 2015
This project started as many of mine usually do, as a honey-do. We have compiled an extensive list of our book and movie collections on our computer at home, but my wife wanted to be able to scan the list from the video store (yes, we still go to the video store). So I created […]
Arduino Powered Binary Clock
Posted on: 07 Aug 2015
This instructable will help you to build an Arduino Binary Clock. The orignial idea for this instructable was designed by Daniel Andrade. My instructable uses surface mount components, but can easily be adapted to through-hole components if you wish. You can follow my other Instructable for Building Your Own Arduino to get started. I would […]
PCB Quadrotor (Brushless)
Posted on: 06 Aug 2015
Quadrotors are the new Segway’s: a mesmerizing, somewhat magical, self-stabilizing platform that every tech person wants to have. You can’t ride a quadrotor (well, maybe you can), but they do fly, and you can build one yourself from scratch! I helped with a previous quadrotor build (Instructable here), and after flying it I decided I […]
Kevin’s LED tester
Posted on: 06 Aug 2015
I’ve made a few devices already that have used 0603 SMD LEDs. 0603 LEDs are beyond tiny and they’re a little trickier to work with when orientation matters. If you look closely at the back of the LED, you’ll notice some markings that indicate which end is the cathode, but in reality it’s really easy […]
Nvidia goes own way with 64-bit ARM CPU
Posted on: 06 Aug 2015
Dubbed Denver, the processor will be used in the firm’s first 64-bit version of its Tigra K1 mobile processor designed for Android smartphones and tablets. This new version of Tegra K1 pairs our 192-core Kepler architecture-based GPU with the 64-bit, dual-core CPU. Each of the Denver cores implements a 7-way superscalar microarchitecture (up to 7 concurrent micro-ops can […]
