View topic - LiquidTWI: High-performance LCD library for I2C Backpack Module
I like fast things. And I like clean code. Often, the two go hand-in-hand ;) After looking through the modified LiquidCrystal library for use with the i2c backpack and darn near crying when I saw all the faux digitalRead() and pinMode() being done on each transfer, I was bound and determined to never let that happen to another friendly Arduino user again. I first made a proof of concept modification to the library to "burst" all the "LiquidCrystal::send" bits instead of digitalWrite()'ing them out one at a time (read I2C, modify, write... read, modify, write... read, modify, write... read, modify, write - over 16 I2C commands for each single character).
Mineways
Mineways is a program for exporting Minecraft models for 3D printing or rendering. The latest version works with Minecraft 1.2 and later (Anvil); Mineways Version 1.15 works with Minecraft 1.1 and earlier (McRegion). The home page is here. This page explains how to use Mineways effectively, with in-depth descriptions of the various options and related resources.
i2c / SPI character LCD backpack [v1] ID: 292 - $10.00
LCD backpacks reduce the number of pins needed to connect to an LCD. LCDs are a fun and easy way to have your microcontroller project talk back to you. Character LCDs are common, and easy to get, available in tons of colors and sizes.
Mini Maker Faire: Make a Maker Faire
Mini Maker Faires are independently produced celebrations of local maker culture. Our Mini Maker Faire program provides tools and resources to help others to make a Maker Faire event that reflects the creativity, spirit and ingenuity of their community. The first Maker Faire started in 2006 in San Mateo, California, organized by the editors of MAKE magazine. Our Bay Area event just completed its ninth year, and has grown into a weekend-long celebration featuring 900+ Makers and attracting over 120,000 visitors. Our other flagship event takes place in New York City, this year with 600+ Makers, and 75,000 attendees. Other larger-scale “featured” Maker Faires take place in Detroit, Kansas City, Tokyo, Oslo, Rome and Newcastle.
Send a Tweet to Your Office Door
It was back to Google, where I soon found a way to do the new Twitter authentication using PHP, a popular programming language for Web sites. That meant shifting the authentication from the Arduino to the Web. I wrote a PHP program that retrieves the tweet and stores it in an XML text file. The PHP code runs on a Web hosting service I use (companies like Go Daddy, DreamHost, and others offer similar PHP capabilities). Using a scheduling tool called cron, I set the PHP program to run every 5 minutes. So here's how the system now works: After I post a tweet, the PHP program retrieves it from Twitter and puts it into an XML file on a Web server.
The Maker Faire App
We are thrilled to announce the release of the World Maker Faire event app, put together by Xomo Digital and some of O’Reilly’s finest. The app is sponsored by HP’s Hacking Autism Initiative. As Maker Faires get bigger, with more to see and do, and more makers to connect with, a good organizing tool is necessary so that you don’t miss any of the action. We’re jazzed by the potential of this one. Some highlights include the ability to drill your way through the schedule (speakers, performances, events), the venues, and the makers, looking at, for instance, all of the talks a given maker might be presenting over the weekend, or all of the presentations happening in a specific venue.
Maker culture
A rekindled interest in manufacturing and hardware, accompanied by the proliferation of inexpensive or less expensive distributed, democratizing manufacturing tools enabled the maker movement to lift off in the mid 2000s. In 2005, Dale Dougherty launched Make: magazine to serve the growing community, followed by the 2006 launch of Maker Faire.[1] The term, coined by Dougherty, grew into a full-fledged industry based on the growing number of DIYers who want to build something rather than buy it. Alongside the movement has come a leveling of playing field, where formerly the creation of products and prototypes required vast resources available only to industry and big businesses. A manufacturing process that is growing in accessibility is driving innovation at all levels. Who is a maker?
