If you’ve ever wondered how cold it is outside, you can find out from crickets! They vary the pace of their chirps depending on the weather. The most reliable formula seems to be the one from the Old Farmer’s Almanac: To convert cricket chirps to degrees Fahrenheit, count the number of chirps in 14 seconds and add 40. To convert chirps to degrees Celsius, count the number of chirps in 25 seconds, divide by 3, and add 4. This will only work down to about 55 degrees Fahrenheit, however, because at that point crickets will start to seek warmer pastures.

Original project by: Владислав Шаповалов Such multi-purpose device is a nice example of of using microcontroller for combined tasks. The idea of radio-clock-thermometer came up when authors car audio head-end was stolen. He decided to use what’s left left from car radio and build something nice. So the project has started.

The migration of popular computing applications to the Web has changed the way we view the web browser. Some of our most frequently used applications now exist within a tab of Firefox or Internet Explorer, constantly polling a remote server on our behalf and presenting the results in a rich interface powered by the latest features of JavaScript and/or the Flash Player plugin. These "live" web applications have pushed the browser to its limits (and sometimes beyond), consuming increasing amounts of memory and network bandwidth as our browser terminal remains connected to the data cloud. Storing data and preferences directly on the user's machine is one way to speed up a web application and even offer some offline capabilities, connecting to data stored on a local hard drive instead of relying on a remote server. In this post I'll walk through some of the ways web application developers take advantage of local storage to speed up applications, persist user preferences, and enable featu

    I found this project on Kifo’s electronic website and I consider it very accessible to beginners. Although it’s really easy to build, it can be impressive to you and to your friends. Nokia 3310 has a LCD with 84*84 dots, that isn’t that hard to get and can be very useful in DIY (do it yourself) electronics. The LCD supports two modes of operation (normal and inverse); the jumper placed on the back of the device is used for changing modes.Negative temperatures are given a “minus”, the bar shows temperatures normally but with an added minus.     The first thing you need to do is to get yourself a Nokia 3310 and start extracting the LCD. You should be very careful and patient during this process, because as you know the display is just a thin piece of glass that is very sensitive. There is an 8 pin connector on the back of the display, in our case it’s glued to the glass (Nokia 3210 has “rubber” connectors so this one is much easier to use). This is a Phillips P

I’ve been fascinated by the LM335 for some time -maybe my obsession with stability finally gave way to my fascination with a circuit with intentional thermal drift. I finally bought some the other day, and to check one out, I hooked it up as a thermometer, based the National Semiconductor application note. The circuit consists of two parts: The LM335 and its adjustment. The output of the LM335 is 10 millivolts per degree C, with 25 degrees C corresponding to 2.982 VDC. A reference circuit provides a zero reference voltage. It is adjusted to (2.982 volts - (25 degrees x 10 millivolts/degree) = 2.832 volts. To read the temperature of the LM335 directly in degrees C, connect the + lead from a high impedance DVM  to the output pin and the - end of the DVM to the 2.732 volt pin. The factor of 10 millivolts per degree C is equivalent to 10 millivolts per degree K, since a change of one degree C is equal to a change of one degree K. The difference in the two scales is only

This Fast-Read Fork Thermometer uses a highly sensitive copper tip and powerful internal microprocessor to give accurate temperature readings in three seconds, less than a third of the time of lesser models. The built-in display will give you information for beef, chicken, pork, and fish, providing the user with the current status whether that is Rare, Medium, Medium-Well, and Well for each. This fork thermometer comes complete with a built-in flashlight. Written by Kerry for Product ReviewsIn Sections: Gadgets & Technology, Summer Gadgets & Products

Tired of the barbecuer in your life waking you up every time they get out of bed to check what temperature the smoker is running at for their over night BBQing? This could possibly be your solution, and a great gift idea to! With the wireless thermometer installed in his smoker all they have to do is role over and check the readout on the clear LCD. It also comes with two temperature probes so that they can monitor separate sections of the smoker, or the temperature of the meat he is barbecuing. If you want to use one of these thermometers in your grill or smoker I have had great success with threading the probe(s) through one of the vent holes, and using a piece of metal wire (paper clip) to tie the probe to one of the metal barbecue grates.

This tip comes from Bertil J. who imports these see-through thermometers. We have see the material before; its a kind of plastic that clings to glass through static electricity. This application, however, is new to us, and we think it is kinda neat. The KleerTemp sticks to your window or glass door (no glue, nails or screws) and is easily readable from the inside. It is available in both Fahrenheit and Celsius versions and it is USD 8:- on ElectroOptix' own web shop. It is also on Amazon- for USD 6:-. Plus shipping, one might suppose.
