Home Sensor Startup Snapped Up

If you knew how much electricity your plasma television used or how much water your dishwasher drank at different times of day, would you change your habits to conserve more and spend less on utilities? Researchers at the University of Washington, Duke University, and Georgia Tech believe that you might. Several years ago they invented sensors that could track the electricity consumption and water usage throughout an entire building via a single point on each system. In 2008, the researchers founded a company called Zensi to commercialize the technology, and last week, they sold that company to Belkin, an electronics hardware manufacturer.

...

The concept behind Zensi's technology is simple: a single sensor is plugged into a wall outlet, where it "listens" to the high-frequency electrical noise produced in the wiring when different devices are turned on. Each electrical device has a signature that is unique to the kind of device it is, its brand, and its location within a house. This information, in turn, reveals its energy consumption. MIT professor Fred Schweppe, and others tested a similar idea more than a decade ago. In the case of plumbing, a sensor is connected to the hose spigot on the side of a house. When a toilet is flushed or a sink is turned on, the sensor detects the characteristic change in pressure.

移到Mega上去 可以Monitor 4個Channel 並加上去邊界設定 不過這樣一來 Sample speed會降到10K以下 我想再加上 Photo Sensor Ouput Emulation的話 應該會降到5K左右吧 這樣就不好用了 因為以一般的步進馬達一圈=200Steps 如果用16x微步的話就是一圈 3200 Clock 一秒才一圈太慢了 加上1:4的減速齒輪的話 一圈都要 12800 clock了 最少要做到20K左右會比較剛好 不過這樣一來 Arduino的速度16MHz 就不夠快了 要搬上Cortex-M3了吧

Arduino Counter for Stepping Motor Emulation

I have write a counter program on arduino to test my stepping motor control program before I got the mechanical from the hardware team. I call it "Motor Emulator". The signals are stepA as the Stepping motor's colock pulse and dirA as the motor rotate direction. The program can track 2 motor at the same time and the pulse rate up to 25KHz (my system's max speed is 20K Step/seconds)

If I use Arduino Mega, maybe I can track 4 motor at the same time.

The right one is the old model use 7-segments , the left one use lcd.

Actually there are still some function need to extend like generate a output when count reach certain count.(Emulate the photo sensor's detection of the mechanical ruler or initial position).

Download MotoSignal.pde <- this generat the signal

Download LCDCounter.pde <- this is the counter code

PS.我這個人最大的問題就是腦袋跑得比手快 這個東西剛開始要做7-Segment版的 才把東西接好 7-Segment driver 測過後就發現其實可以 Track 2顆馬達 這樣用LCD比較方便 於是就今天就直接用LCD的版本 不過其實並不是很想寫 因為晚上就想到 那乾脆用Graphic LCD版的話還可以劃出真正機械的位置....不過這樣下去沒完為了 (直接上PC是不是更方便) 加上手邊也沒有Graphic LCD模組可以馬上給Arduino用 就老實的把Counter寫完了

How Google’s Tablet Can Challenge The iPad.

The Open Road to Success

The iPad isn’t perfect. The Google tablet won’t be perfect. But Google needs to be different and it does not hurt to look into the past of personal computing to see what has worked in the past and what has not. Convenience is what most users are attracted to, but choice is Google’s biggest opportunity to show users how limited the iPad really is. Google has a true chance to inject excitement into computing again. Let’s hope the Google tablet will be a great copycat of the tablet vision and not just a copycat of the iPad.

eLua User Lab

The best of eLua is you don't need any compiler to compile your code. All you need is a Terminal.

Pirateship Bus Pirate GUI

This program's first version was created usig the Qt toolkit, which allowed very fast development.

The most interesting feature, beyond storing previous commands to facilitate the usage of repetitive protocols, is to allow the configuration of an interval timer that automatically repeats a command. This is extremely useful in sensor evaluation, where some data could change very subtly, which are hard to notice when one has to retype a command several times, and for each time eye-scan for a variable in a different position of the terminal.

Apple removes Scratch from iPad/iPhone/iTouch

A real bummer — Apple removed Scratch from the iTunes store, so it’s no longer available for iPad, iPhone, or iTouch.  Why?  Discussion on the Scratch forums suggests that it’s because Apple wants to focus on consuming media using these devices, not producing media.  Want to be truly computing literate, where you write as well as read?  There’s no app for that.

I saw this coming. Apple has banned all third party software from creating ipod apps. What they did to scratch was nothing compared to what they did to Adobe. Flash CS5’s biggest feature was the ability to make flash programs for the iphone and because Apple has banned this the usefulness of flash CS5 has gone down a lot.

Its a business decision. Apple wants to be in complete control of what can make apps for their machines so they ban all app creators except their own. Of course, they can take all the hate from developers because the mindless Apple legions will still love them.

這下子我真的討厭Apple了! 爛蘋果 根本就是白色恐怖 , 應該可以告告他吧！

PS.

Scratch is a programming language that makes it easy to create your own interactive stories, animations, games, music, and art -- and share your creations on the web. As young people create and share Scratch projects, they learn important mathematical and computational ideas, while also learning to think creatively, reason systematically, and work collaboratively. Scratch is developed by the Lifelong Kindergarten Group at the MIT Media Lab, with financial support from the National Science Foundation, Microsoft, Intel Foundation, Nokia, Iomega and MIT Media Lab research consortia.

ChibiOS/RT another Free Embedded RTOS

Brief Description

ChibiOS/RT is designed for deeply embedded real time applications where execution efficiency and tiny code size are desiderable features.

The system is implemented as a library to be linked with the application code, the OS and the application code together form the image to be loaded on the target device.

Features

The kernel provides a rich features set, it offers: preemptive multithreading, 128 priority levels, optional round-robin support, unified interrupts handling, support for preemptable interrupt handlers, virtual timers, semaphores, mutexes, condition variables, synchronous messages, mailboxes, event flags, Abstract Channels, I/O queues, heap and memory pools allocators.

Of course, the above mechanisms are not always required in most applications, it is possible to selectively exclude the unused subsystems reducing the total code size.

Size

The kernel is very compact, on a reference Cortex-M3 (STM32) platform the kernel size ranges from 1.2KiB minimum up to 5.2KiB maximum size. Size metrics are available for all platforms, as test reports, into the source distribution.

Performance

On a reference STM32 platform clocked at 72MHz the kernel is capable of context switching in 1.41 microseconds, taking/releasing a semaphore takes 1.21 microseconds, spawning a thread (the whole create-execute-terminate cycle) takes 4.64 microseconds.

The timings are measured using the internal test suite, it is possible to inspect the benchmarking methodology and replicate the results by simply running the included demos. Performance metrics are available for all platforms, as test reports, into the source distribution.

Memristors for artificial intelligence?

via BoingBoing

Now, University of Michigan computer engineer Wei Lu and his colleagues are exploring memristors as the foundation for the memory and learning functions in a future electronic brain modeled on that of a cat. (For info on other efforts and controversies around cat brain simulations, see IEEE Spectrum's "The Cat Brain Cliff Notes") In Lu's work, the memristors act as synapses.

Synapses就是神經細胞的對外輸入 一般神經細胞是多個輸入一個輸出 而神經細胞間的連結強度與架構才是決定功能的關鍵 不過神經細胞間的連結是有強度而不只是0與1

Liquid Level Detection

Capacitive liquid level detection  A weak electrical potential is created between the pipetting channel and the labware carrier.  When using conductive tips (black) and an ionic liquid the capacitance of the circuit is measured.  From this data the software can determine the hieght of the liquid surface and take appropriate action.

Pressure liquid level detection  A pressure transducer inside the air displacement channel measures the pressure inside the barrel during pipetting.  The data from this sensor changes as the tip approaches the liquid surface, touches the surface and drives below.  This data can be used to control pipetting in real-time.  Pressure level sensing is the only way to determine the level of non-ionic liquids.

Windows CE: SDK Doesn’t Show up in Visual Studio 2008

via Bruce Eitman

The actual instructions from Microsoft Support are:

1)      Make sure Visual Studio 2008 is not running. I also shut down the device emulator manager but you may not be using that.

2)      Open a “Visual Studio 2008 Command Prompt” as Administrator. On Windows 7 just right click the short cut and pick the “Run as administrator” option.

3)      Enter the following command: msiexec /log SDKInstallLog.txt /package <the path to your .msi file>

4)      When asked if you wish to do a custom or complete install pick custom

5)      Instruct the installer to omit the installation of the documentation. This was something I found about CE 6 SDK installation issue and may have no bearing upon your problem but I did it anyway.

6)      Install
