Arduino Selfie

My attention is drawn towards the noise behind me. I cannot believe it. There it is. The Arduino is taking a SELFIE !! How did this happen? Well actually, it is not that difficult for an Arduino. I found out that my Canon Powershot SX50 HS camera has a port on the side for a remote switch. In the "Optional Accessories" section of the camera brochure, it identifies th.......

Arduino Siren Sound Generator Circuit - Customizable Arduino Siren Sound Generator Circuit - Customizable

The proposed Arduino siren sound project generates the tone of a perfectly imitating siren sound which can be customized to produce many different siren effects simply by making relevant modification in the sketch. A siren sound, as we all know is a loud noise generated through a device designed for producing this sound either through a mechanical approach or through electronic circuits. Siren sound generator devices find many useful applications and are used in emergency service vehicles like i.......

Silicon Chip Online - High-Performance Microphone Preamplifier

High-Performance Microphone Preamplifier - Some recording devices, especially computer sound cards, have poor sound quality or insufficient gain when used with certain microphones. This tiny module provides a line level output from an unbalanced or balanced microphone and has very low noise and distortion. It runs off 5-20V DC, consuming just 6mA. This compact module accepts either a balanced or unbalanced microphone input and provides a line-level output with very low noise and distortion. It r.......

Auduino With Delay

This is the first in a series of posts introducing simple audio effects that can be used in micro controller projects. Next Week - Bit Crushing effectsThe Delay effect is one of the simplest and most effective enhancements we can add to our audio projects. The delay effect works by recording the output as it is being generated and then mixing this sound back in with itself - after a delay. The result should be familiar to anyone who has every played an electric guitar through an amp with reverb........

Practical MC13224 Firmware Extraction

by Travis Goodspeed as presented at CONFidence Krakow, 2011. MC13224Pictured above is a Freescale MC13224 chip, having been partially decapped with nitric acid in my lab. This is the chip used in the Defcon 18 Ninja Badge and the Redwire Econotag. This brief demonstrates two methods for extracting the firmware from an MC13224 or MC13226 which has been read-protected by placing "SECU".......

DIY Canon Intervalometer using Arduino

An intervalometer allows you to take photos at set intervals to view a slow process in super fast speed.Watching paint dry is just as boring in fast motion as it is at normal speed, however, when you point your camera to the clouds in the sky, you can get some amazing effects. By taking a picture every 3 seconds, and then playing the sequence back at 30 fr.......

Experiment 14 (Chapter 14) -- The Joy of Wiring!

First, I'd like to say for anyone following along that I'm sorry for the delay in getting a new experiment posted.I'm teaching an after-school science project club at my sons' school and have spent the last few weeks getting equipment, supplies, and instructions together along with fine-tuning the projects. The club has kicked off and is going fine, and things have calmed dow.......

LTM2886 - SPI/Digital or I2C ?Module Isolator with Fixed ±5V and Adjustable 5V Regulated Power - Linear Technology

The LTM®2886 is a complete galvanic digital μModule® (micromodule) isolator. No external components are required.A single 3. 3V or 5V supply powers both sides of the interface through an integrated, isolated DC/DC converter. A logic supply pin allows easy interfacing with different logic levels from 1. 62V to 5.5V, independent of the main supply. Available options are compliant with SPI and I2C (master mode only) specifications. The isolated side includes fixed ±5V and 5V adjustable power .......
