I found several different magnetometer designs on Internet, but I tend to be very picky. None of those was what I needed – something that is sensitive enough to record the small magnetic field variations where I live (San Jose, California), robust enough to work for long periods of time without constant maintenance, and relatively

I have seen many examples of microcontroller oscilliscopes on the web and have had an itch to build one myself. In order to accomplish this my initial thought is to sample an input (ADC) at consistant time increments and then display the waveform on a graphic lcd display. If I want to change the time

ABSTRACT The heart rate is an important measure of health and physical fitness. Medical professionals rely heavily on the rate as a measure of health status and use it to prescribe treatment to individuals. Athletes value the heart rate highly as a tool for regulating frequency and intensity of workouts because the rate provides a

The brushless DC (BLDC) motor is becoming increasingly popular in sectors such as automotive (particularly electric vehicles (EV)), HVAC, white goods and industrial because it does away with the mechanical commutator used in traditional motors, replacing it with an electronic device that improves the reliability and durability of the unit. Another advantage of a BLDC

This Programmer is powered by the RS-232 and it works with RS-232 levels at only < ±8.6V. It programs PIC12C5XX, 12C67X, 24CXX, 16C55X, 16C61, 16C62X, 16C71, 16C71X, 16C8X, 16F8X and ISO-CARD’s with ASF. Other serial programmable chips by adapter. The high Vpp is obtained by using negative voltage to drive the chip. The voltage is
