DIY Digital Tape Measure

by electronics for everyone @ instructables.com:

Today I hope to teach you all about ultrasonic sensors and hopefully by the end you’ll have a nice little digital tape measure of your own to use as you please. This is my second version of this project so if you can get it as small or just don’t feel like dealing with the Arduino Pro mini feel free to change it in any way you want.

by Matej Blagšič @ instructables.com:

My father asked me to do a little project with Arduino that would send an e-mail when a push button is pressed or anything, can be based on temperature reading, so make sure you watch my previous instructable on that or to send that something has closed up on the distance sensor. Be sure to watch those tutorials on my profile.

Simple Infrared PWM on Arduino, Part 3

Original-2-Signals-AnalysIR-600x338

The crew from AnalysIR has written up an article on Simple Infrared PWM on Arduino. If you missed part 1 and part 2, be sure to check it out.:

In Part 1 of this series, we demonstrated how to send signals using soft or Simple Infrared PWM on Arduino. In our Part 2 post we looked at sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal using soft PWM. We have since improved the PWM method shown in Part 1 & Part 2 to provide better performance and improve portability. In this Part 3, we will take the signals from Part 2 and show how to send them using their binary (or Hex) representation, which can save lots of SRAM in many projects, particularly when dealing with longer AC signals.

Mesa-Video : 800×600 Digital video for Arduinos

img_11001

blackmesalabs.wordpress.com has build a video system for Arduino boards:

This post describes Mesa-Video, a low cost, low power, small size and fully Open Source Hardware and Software solution for providing 800×600 digital video for Arduino ( and other ) microcontrollers. Mesa-Video makes it quick and easy to display text and 24bit color graphics from any MCU using a single UART serial port pin. Applications for Mesa-Video are embedded projects requiring video output and embedded developers wanting real time visibility into their system operation. Mesa-Video is the 1st of multiple Mesa-Modules planned.

Burning the Bootloader on ATMega328 using USBasp Programmer

ATmega328 Arduino bootloader

by openelectronicsproject.blogspot.com:

In this tutorial you’ll learn how to burn arduino bootloader on new ATmega328 using USBasp ISP programmer.Please be noted that every Arduino Board comes with a microcontroller ATmega328 pre-program with arduino bootloader firmware. Therefore, there is no need to burn the bootloader firmware again.But if you want to make your own DIY arduino board than you need to burn arduino bootloader into ATmega328. So here i’ll show you how to load arduino bootloader into atmega328 step by step.

DIY USB Line Power Meter Stick

DIY-USB-Line-Power-Meter-Stick-Connected-to-Laptop-620x503

a new project is published on electro-labs.com, check it out:

Another DIY project designed with FabStream’s SoloPCB tool is ready to be shared with Electro-Labs community. This is an USB stick which measures the supply voltage of the USB port and current drawn by the device connected to the port over the stick. Then it calculates the power consumption of the device and displays the whole information with the help of the small OLED display on the board. The stick itself is also powered from the USB port.

The board is built around an Atmel ATMEGA328 microcontroller. To make the circuit as small as possible, the MCU is used in minimal configuration. Internal 8MHz oscillator is used. The voltage and the current are measured by the internal 10 bit ADC. To make the measurements more accurate, an external 2.5V voltage reference IC, Microchip MCP1525 is included. The current is converted to voltage on a 0.01R sense resistor and precisely amplified by LT6106 before read. The stick can measure up to 2.5A. Since the OLED display requires 3.3V supply voltage, L78L33ACUTR linear voltage regulator is used.

iHome – Intelligent Thermostat Project

by jwozniak @ jwdevs.com :

The world of IoT for “Smart Home” is growing very fast. There are various areas of interests from security to automated animal care depicted for instance on this page.

I’ve tried to look at the things from the practical point of view. What would be interesting enough to be build as a project and at the same time have a real, quantitive value? It happens that I was always interested in limiting the energy consumption at home. One evening when talking to my wife and trying to get her opinion on my adventures into electronics she said that it would be great to have a heating already on before she gets home (and a cosy, warm place ready exactly when she enters). I guess she said it as a kind of a joke. To her surprise I got attracted by the idea. Hey, why not? With the current state of technology it is actually feasible. Maybe a bit challenging at first sight but still. So this is how it has started. Let’s build a intelligent thermostat that would be off when we are not at home and turning on when we come back! Great! Let’s see, maybe it will even improve the energy consumption…
