The project it’s based on a nice little 3-axis accelerometer from STMicroelectronics with a SPI bus, which makes it handy for interfacing in microcontroller style applications. This device could be interfaced with an AVR, but the author chose to interface it with the Arduino, since it’s pretty easy to get up and running in that environment.

This project will make use of the MAX6675 Cold-Junction-Compensated K-Thermocouple-to-Digital Converter. It basically takes the millivolts produced by a standard K-type thermocouple, amplifies it, and outputs it’s temperature reading. This reading is received by a microcontroller, which then displays the reading on an LCD display. This unit will be capable of reading temperatures up 1800 degrees fahrenheit.
As you can see the author of this project also used adapters for smd parts. Myself i like to work directly with SMD parts, but sometimes it’s just not possible, especially when prototyping because you always have to tweak something.

This is actually version 2 of the syringe logic probe, so it has some improvements over the first one. The advantages of using a syringe as a logic probe are obvious, you can reach small pins or solder points. The probe wassn’t yet tested at high frequencies, but it works well enough for sniffing AES keys from an SPI bus.

This simple circuit is designed to report the temperature via any standard FM broadcast band radio at regular intervals. It uses a simple low bit rate tone signalling scheme which can be interpreted easily by both humans and machines. Such a device can be used stand-alone or as part of a PC-based weather station or HVAC system.
There are endless practical applications for such a device, just think about how many time you wanted to measure a temperature and for that you needed to run wires to the sensor. Now with this circuit you can place the device where you need the temperature reading and no more wires need to be connected.

At this thermometer, the IC thermo sensor (S8100) or the diode (1S1588) is used as the thermo sensor. When using the IC thermo sensor, the thermometry to +100°C from -40°C is possible. Also, when using the diode, the measurement to +150°C from -20°C is possible. Both sensors are contained in the kit.
