1-Wire Barometer

Catagory : Physical instrument, Uncategorized
This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. The goal of this design was to make a simple reliable 1-Wire barometer with reasonable pressure resolution and one which could be constructed without a specialized printed circuit board by a hobbyist.This design uses a Motorola MPX4115 Silicon Pressure Sensor, a Dallas Semiconductor DS2438 Smart Battery Monitor (to perform 1-Wire analog to digital conversion), an operational amplifier, a voltage regulator, a diode, and several resistors and capacitors.

BASIC Stamp Seismometer

Catagory : Basic Stamp, Physical instrument
A simple, yet capable, seismometer that teachers can use to instruct the fundamental principles of seismology can be constructed using a Basic Stamp and two Memsic 2125 accelerometers.Each accelerometer has two axes. One accelerometer for the X and Y-axes and one accelerometer for the Z-axis were used in the prototype. The Memsic accelerometers are capable of measuring up to +/- 2 gs with a resolution of about .001 g. Taking into consideration the 32-bit limitation of the Basic Stamp and the 2uS resolution for measuring pulse width, the combo can resolve to around .002 g. [...]
