  • Wiring the Cobbler to the LCD | Drive a 16x2 LCD with the Raspberry Pi | Adafruit Learning System
    Notes
    Whenever you come across a LCD that looks like it has 16 connectors it is most likely using a HD44780 controller. These devices provide the same pinouts making them relatively easy to work with. The LCD uses a parallel interface meaning that we will need many pins from our raspberry pi to control it. In this tutorial we will use 4 data pins (4-bit mode) and two control pins.

    Notes
    This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs.

  • 3-Wire Serial LCD using a Shift Register
    Notes
    HD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to demonstrate it with PIC12F683 microchip. The character data and command from the microcontroller is transferred serially to a shift register (74HC595), and the parallel output from the shift register is fed to LCD pins.

    Notes
    The three models (all of which we use here at Digital Diner) are the Arduino, Raspberry Pi and BeagleBone. We chose these three because they are all readily available, affordable, about the same size (just larger than 2″ x 3″) and can all be used for creating wonderful digital gadgets. Before we get to the comparison, here is a brief introduction to each one.

    From the moment these LED displays made an appearance on our weekly Ask an Engineer show, comparisons were being made to the DeLorean time circuit from the Back to the Future films.

    Notes
    Tweet-a-Watt is a DIY wireless power monitoring system. The project uses an 'off the shelf' power monitor called the Kill-a-Watt and adds wireless reporting. Each plug transmits the power usage at that outlet to a central computer receiver. The receiver can then log, graph and report the data. This pack contains nearly everything* necessary to build a single outlet monitor and receiver. To monitor additional outlets, you will need an add-on transmitter pack. One outlet can monitor up to 1500 Watts.

    Marriage is a sacred commitment; it's no kind of small thing to consider. You need to show you mean business. You need to put some effort into a proposal. Jered McFerron did when he decided to rewrite the code for the 1986 NES classic, Metroid, in the C++ programming language. This undertaking wasn't initially to propose to his love, Jenni, but struck as an inspiration mid-project when he knew she was the gal for him.

    Notes
    It has been pointed out by chunkhead from the afterdawn.com and llama.com Forums that some X-Box motherboards have a corrosion problem on some traces. This corrosion is due to some sort of contamination from the factory. Due to this corrosion, it was found that some X-Boxes affected can produce the following symptoms: (1) The X-Box fails to power down using the power on/off button on the front panel. The power cord has to be pulled out to shut it down. (2) As soon as the power cord is plugged in, the X-Box powers up without pressing either the on/off or eject buttons. (3) While the X-Box is on for a certain amount of time, it shuts down by itself for no reason. The time factor before shut down can vary wildly.

  • Home-Brew and the DIY innovation movement. - Slate Magazine
    Notes
    We can learn several crucial lessons from this diverse, creative group, and that understanding will allow us to encourage innovation. For some, the main impetus for DIY is that it provides an outlet from their daily grind: Many employees suffer the life of the cubicle-bound "knowledge worker." In his best-selling Shop Class As Soulcraft, Matthew Crawford argues that the elimination of industrial arts and home economics classes from public school curricula has left us dependent on machines that we don’t understand and frustrated by the outsourcing and off-shoring of production. We also derive little satisfaction from what we “produce” at work. We’ve become a nation of shoppers and consumers. DIY is a way to engage the physical things around us and create durable (and drinkable) objects. Based on informal conversations with other DIYers, some of these motivations include self-reliance, community-building, autonomy, independence from monopolies, an alternative to rampant consumerism, innate curiosity, and the desire to make something cool.

  • Practical Arduino: Virtual USB Keyboard
    Notes
    Communicating with a host computer can allow a simple Arduino-based system to gain access to a wide variety of devices and information. Most people link an Arduino to a host using serial communications across a USB connection with custom code running on the host to send information to the Arduino or receive it in return, but giving your Arduino the ability to pretend to be a keyboard or mouse opens up a whole world of possibilities because it means your Arduino can interact with software that was never intended for external control. That could be desktop software such as a game or a web browser: your Arduino could "type" into a web form and submit it on your behalf, or act as a custom controller for a game!

  • eSleeper combines cats, Arduino and Twitter in an eMac shell (video) -- Engadget
    Notes
    If we had to imagine our dream DIY project chances are it would involve Arduino, Twitter and, of course, cats. How we'd combine those things we're not sure, but we'll admit to being big fans of Samuel Cox's eSleeper, which turns a hollowed-out eMac into a bed for his feline. Inside the shell is an Arduino Ethernet connected to an IR sensor, some LEDs and a sound shield. When the cat breaks the infrared beam it triggers the iconic Mac chime and turns on a series color-shifting LEDs for a little mood lighting. From there the clock starts ticking. When little Fluffy (Captain Whiskers? Matlock? Penny? Greg?) decides she's had enough napping and leaves the white plastic cocoon, tripping the IR sensor again, a random phrase is tweeted, along with the length of the cat's siesta. Check out the video after the break to see the eSleeper in all its adorable DIY glory.

  • Microwave hack uses Arduino and TouchPad to play perfectly-timed YouTube videos while you cook | The Verge
    Notes
    The ÎźWave is a hack involving an Arduino and a TouchPad taped to a microwave door, which plays YouTube clips perfectly matched to your cooking time. This Frankenstein uses the Arduino to send data from the microwave's seven-segment displays to a web server, which finds a highly-rated YouTube video of the right length. The web client running in the browser treats you to a video clip that ends right when your food is done, then optionally tweets or sends a text message. The hack was created by students at the University of Pennsylvania, where it won first place in the PennApps Hackathon. There are no stated plans for commercialization, but the team will present the project to Google as part of the grand prize. If Mountain View announces a microwave any time soon, we'll know to expect great things.
