I will qualify this. If you are a programmer used to an IDE, Arduino sucks. It wes made to allow painters, breadmakers and other artists to make embedded elements, and maybe for a non-programmer, it may be the only (and best) thing out there.

I tried this and dropped it fast. Instead I ended up using Code Composer Studio. It works like a charm for all TI's boards. Try out the 430 development system on sale for $4.30. Great IDE with in circuit debugging and all the other features you are used to, and you are up and running in no time.

Android is also a good choice, powerful, but a little different if you are used to C/C++ insted of Java. Not only for phones but a lot of other embedded devices as well.

BTW, You can get used Samsung Galaxy with a new battery for $100. It is an incredible embedded device, and if you want buy an Arduino device with even a small part of the features, you will pay many times this.
!GHz ARM, 16BG flash, dilsplay,WiFi, Cameras, Graphics engine, xyz accelerometers, maybe gyros. If you need USB master you have to get android 4.0 based device.

The internet is basically a copy machine. I realized this writing an IP stack. It might as well be called the interCopy or the big copy. This word may also make it clear for the distributor that if you put your stuff in the interCopy, it will be copied. That is what the interCopy does. If you do not want your stuff copied, just don't put it in the interCopy.

The (not so big) secret is that most WiFi AP rolls over with 8 or so clients. Only a few manufacturers themselves test their products beyond that, and those work all the way to over 100.
The company selling the test equipment you need is called http://veriwave.com./ You can buy the equipment from them and test all the vendors, or even better, just ask them.

They do of course know, since that is how they test their own test equipment. Problem is that they can/will not tell you because then 1. you would not need to buy their product, and 2. AP mfg would fix their products, and Veriwave would not have a market for their products.

Maybe just do some social hacking to get it out of them.

Comment: Stack implementation, MIMO and ch. 14 (Score 1) 251

I wrote code for the 802.11b stack, and have gotten a lot of feedback from the test team as well, and here is my 2c:
1. Stacks should handle at least 127 radios on one channel, but most implementations crash with as few as 8 radios alive. Make sure you use a stack that handles many radios. Test your router and your gear (netgear and D-link passed, but check with your current router anyway)
2. Nearby channels appear as noise. If you have many TX on nearby channels, you may not have enough signal/noise ratio. Make sure all gear is MI-MO, and maybe add directed antennas to your router that keep your signal strong in your area.
3. Use channel 14 (you may want to check legality of this in your area) Standard US HW is limited in FW to use ch1-11. Ch 12,13 and 14 is all in virgin territory, and you would be alone at those frequencies, unless of course, you traveled to Spain or Japan or other where you this would look different.

I have also been working on a buzzworkd generator. I included words: Cloud-based, linux kernel, android, Mobile, platform, global marked. the OPs also included the words: virtual machine, apps, chinese, smartphone. What a powerful buzzword generator!

I am also impressed by the bold juxtaposition of buzzwords in one sentence: Android compatible Cloud-based linux kernel.

I hope nobody here on /. will destroy this beauty with any attempts at understanding what it is, or what it possibly can mean.

Californias power infrastructure is massively defective, and outages are similar to third world countries. You can not "test" in quality. Money would be better spent building solid reliable infrastructure replacing the existing. Electric power fails more than once a year, and gas lines explode in residential areas. It should be the norm to *never* have electric outages.

Comment: Dolphons speak 3D sonar. (Score 4, Interesting) 179

by viking80 (#36099076) Attached to: Translator Puts Us Closer To Dolphin Communication

dolphins use sonar to geolocate and find food. The sonar pattern used also depends on whether they are navigating, searching for prey or attacking. When a dolphin "tells" where to go to find fish, it will play back a stylised summary of the sonar imagery from navigating past the steep cliff, to "seeing" the school of 1kg macrel, to the successful attack.

This 3D communication is efficient and fast, and connects directly to the visual part of the brain. Powerful and emotional imagery can be communicated well.

Humans 1D voice communication compared is inefficient, indirect and lack precision and descriptive elements.

"Riding a bow wave" is a 1D sequence of sound that has very little info or precision compared to the sonar echo of actually riding the wave.

Humans should probably try to speak sonar, rather than try to dumb down a dolphin to speak human

You're definitely on their list. The question to ask next is what list it is.
