The other way is to set a simple server, either with dns or full ip, so your modem will send its local ip to this server at connect. It may then querry the required...

    gl 100 +gps Hi Aslm, The cpu I use is the WMP50/100/150 depending on the application. For automotive spec, the 150 is the only one that goes to 125°C. The combo can be any, but the minimum required is this size. As you update the firmware you need at least twice the size prior to...

    how to flicker a fluorescent light

    Hi Basically a fluorescent lamp is like a spark gap. i.e. if you rise the voltage slowly nothing happens, until around 90 Volts it shorts. This is why normally you need a big inductor to hold the current down. So at old fashioned way, it will flash 120 times per second on a 60Hz AC. Electronic...

    Speech Recognition by Hardware

    Hi What we did here in Brazil was to record a set of some 100 words from about 16k people over the country, each one with its own accent. Then we mounted a phonetic translator that recognizes any person talking. The pnhonetic lib takes up 1MB The you put plain text on your application, like yes...

    Hi all I think you really should go for ZigBee. Everybody is now hopping in like Ember, STM, Atmel, even TI that bought chipcon.... But from my own expertise, you should stay out all those vaporwares.... I mean by ember, atmel, ti/chipcon, st and freescale...... You pay a lot, NDAs, volume...

    Freescale MC 13192 or Chipcon CC2420 ?

    freescale 13192 zigbee Dear Friends. Now that Ti has bought Chipcon and ST Micro is licensing Ember's 260 chips, seem that these "diammond" ZigBee sponsors are scaring Ericson to the bones. They now plan some "improvements" on the Bluetooth stack. Anyway, I've been trying to use all this stuff...

    does any one have experience with cc1000 by chipcon

    I used it some 4 years ago and it seems realy cool. As it has a digital pll its very easy and fast to do the frequency hopping. This chip has received lots of awards

    How to calculate velocity?

    Hi Once ye ol"Newton said F=m*dQ/dt So a Force can be expressed in a constant m currently known as mass times the variation of the Quantity of movement in time. So the force neede to "throw" the object deppends in this formula. Newton "never" said that dQ/dt == acceleration, this is a simplified...
