No one would argue that airbags and brake and engine controls are critical
safety-related automotive electronics systems. There are those who contend
that, because of the growth in the number of automotive electronic systems,
and the in-vehicle networks connecting them, most auto electronics are
safety related to some degree. Check out one of the top How To stories on
our homepage which makes just such a case.

How supercapacitors solve LED flash power issues in high res camera
phones -- Part 1
How do you get the high intensity flash needed for camera phones with more
than 2 megapixel resolution? Traditional LED flash driver circuits can
exceed the battery's capability but here's an excellent alternative solution
that meets the size limitations and power requirements.

Ideia de Montagem, circuito experimental

What Is an iButton? -  This application note is a broad introduction to the
iButton. It discusses the iButton basics: what it is, how it is constructed,
and some of its applications. It explains how a system can communicate to
the iButton through its 1-Wire interface. The note also describes: types of
iButtons; iButton durability; its guaranteed unique 64-bit serial number;
and available iButton accessories.

Configurable logic gates' Schmitt inputs make versatile monostables

Building a 1-Wire Temperature Logger Using the MAXQ3210  - This application
note describes a temperature logging application using the MAXQ3210
microcontroller and the DS1822 1-Wire Digital Thermometer. Temperature
values are logged into the MAXQ3210's internal EEPROM for later download and
analysis.
