Mesh Sensors The Touch-Friendly Web Keeps on Growing In December 2009, mobile search engine Taptu found about 326,000 touch-optimized mobile sites on the Internet. By April 2010, this number had grown by over 35%. According to Taptu's latest report, there are now over 440,000 touch-enabled sites on the Web. Growing Much Faster than Expected In the company's last report, Taptu estimated that the size of touch-friendly Web would reach half a million sites by the end of the year and about 1 million by the end of 2011. The reason for this rapid growth is surely the increasing popularity of touch-screen phones and touch-screen enabled devices like the iPad. These retailers and publishers could obviously also opt to just develop native apps (and many currently do both), but thanks to HTML5 and other new technologies, it will become increasingly possible for developers to create mobile web apps that will feel more and more like native apps.

Introduction Computer mice are ubiquitous. Figure 1: An LED illuminates the desktop surface, which is imaged by the mouse sensor. Theory In past times, mariners could tell how far they had travelled in a given day by sighting the stars each day, and noting the differences from one sighting to the next. Figure 2: A detail of our example surface.Elaborating on this, Figure 2 shows a hypothetical surface area under the mouse. The mouse sensor is essentially a camera. From these, we can tell that the mouse has traveled a distance equal to -3 "pixels" in the X direction and +2 "pixels" in the Y direction. Figure 3: The world from the mouse's perspective at times A & B. Mouse navigation is by dead reconning. The discussion above covered mouse navigation in two-dimensions. Figure 4: Block diagram of an optical mouse. SW1, SW2 and SW3 The ceramic resonator provides a timebase for IC2.
System - Openmoko SB-Projects: IR Remote Control, NEC Protocol NEC Protocol To my knowledge the protocol I describe here was developed by NEC (Now Renesas). I've seen very similar protocol descriptions on the internet, and there the protocol is called Japanese Format. I do admit that I don't know exactly who developed it. Features 8 bit address and 8 bit command length. Modulation The NEC protocol uses pulse distance encoding of the bits. Protocol The picture above shows a typical pulse train of the NEC protocol. A command is transmitted only once, even when the key on the remote control remains pressed. Extended NEC protocol The NEC protocol is so widely used that soon all possible addresses were used up. The command redundancy is still preserved. Keep in mind that 256 address values of the extended protocol are invalid because they are in fact normal NEC protocol addresses.

Dream. Design. Do. » Blog Archive » Reversing an RGB LED remote I have this dream to someday light our basement with RGB LEDs. They often come with remotes and controllers, which are surprisingly inexpensive. The problem with the remotes you get for cheap on ebay is that you *have* to use the remote to change the lights, and that of course limits you to the buttons on the remote. I’d like to make an in-wall dimmer/color changer for LED mood lighting, but with the added feature of being compatible with the existing cheap LED remotes on the market. That means reverse-engineering one. Hardware What’s the first thing I do when I get a new gadget? There’s a 256-Byte two-wire serial EEPROM in the top left, a 5V linear regulator along the lower edge, and an unmarked 16-pin IC that is the main controller. I’m really not sure what the serial EEPROM is there for–perhaps the memory setting I couldn’t get to work? IR Protocol I soldered a couple leads to appropriate points and hooked it up to the oscilloscope to capture the incoming signals. Outputs
