Write energy-efficient C code

Write energy-efficient C code

H264DecoderBrian sent this along, something to consider if you’re working on small form factor devices…It’s good for the environment, good for your batteries, but it’s weird to think about an algorithm’s energy efficiency (it’s not just CPU cycles they look at, but memory access as well) “PowerEscape has added a new utility to its development toolsuite. “Insight” aims to reduce power consumption by improving the “data efficiency” of C-language code. The company says improving data efficiency in the initial stages of development yields higher performance for the same amount of power.Link.

PocketMod: Make a disposable personal organizer

PocketMod: Make a disposable personal organizer

HolditRael had a great idea, use these PocketMods for Make for shopping lists and instructions for a project. “The PocketMod is a new way to keep yourself organized. Lets face it, PDAs are too expensive and cumbersome, and organizers are bulky and hard to carry around. Nothing beats a folded up piece of paper. That is until now. With the PocketMod, you can carry around the days notes, keep them organized in any way you wish, then easily transfer the notes to your PDA, spreadsheet, or planner.” Link.

HOW – TO: Getting Started with RSS

HOW – TO: Getting Started with RSS

62715536 57Dd85E1D6 OPaul writes “If there’s one word to describe my latest article, it’s comprehensive. Focused on using RSS as a means to save time in one’s daily routine, I take the reader through what RSS is, why it should be used and how to use it. I go through the installation, configuration and usage of RSS in Thunderbird, Google Desktop, RSSOwl as well as web-based feed readers with Google’s Personalized homepage, My Yahoo!, and Bloglines. As with all of my articles, there’s screenshots-a-plenty.” Good one to send to the non-RSSers, or if you’ve always wondered what those XML and RSS buttons are on MAKE. Link.

Beck video with Sony QRIOs now live…

Qrio
Mocapitator let us know that the new Beck video we mentioned, starring the Sony QRIO robots is now live on the Beck site. I just watched it and I think the QRIOs are a lot more interesting than their role in the video. I worked on a few Sony projects in the past in Japan and China, some with the QRIOs and they’re creepy-cool. If you’ve seen the QRIOs in action, then this video might not seem that interesting, it’s pretty much their dance routine when they’re out in public – but still fun to watch. Link.

HOW TO – Spinning LED

HOW TO – Spinning LED

Spinning MarqueeGreg sent in this great LED project that spells words or makes patterns when it spins “The way this works, is you have an EEprom (electronically eraseable programmable read only memory). This stores data on different lines. You retrieve this data by feeding it binary numbers, (ie. 1=0001, 2=0010, 3=0011, 4=0100, and so on). Each line of code has 8 bits of data, and directly corresponds to how the row of LEDs are lit up. If you put in 10000001, then the top and bottom led would be on. This is kind of tricky to figure out, but you have to make a grid. Since I am using a 4 bit counter, I have a possibility of 16 addresses. So to make a letter, you have to draw up a 16X8 grid, and color in the pixels you want.” Link.
