This document describes how to read a capacitive humidity sensor directly from a micro controller using 1 resistor, 1 diode the sensor and two IO lines. It does this without an ADC by measuring the amount of time it requires to charge the capacitor through a....

This is a chronological account of a project I am working on: to design and build my own digital clock. I was inspired by the KABtronics Transisitor Clock. That one is made completely from discrete components, but I wanted to do something less ambitious. I....

This receiver is a modification of Charles Wenzel`s Two Transistor Reflex Radio. Instead of a ferrite AM loopstick antenna, I use a magnetic loop antenna, and I added an LM386 amplifier stage to drive an 8-ohm speaker. There is a switch to select whether....

The input and output data streams of the I and Q data channels are shown in Pi/4DQPSK System: fc=990 MHz, Data rate = 48. 6 kbits/sec. Note the delay between the input and output data signals. This delay is due to the filters in the modulator and....

GMSK_Demod is a model of a suboptimal (an optimal receiver would require the Viterbi algorithm) coherent GMSK demodulator (refer to the GMSK_Recovery component). Noncoherent demodulation can be performed with the FM_Demod component. Pin 1 is the input for....

It`s based on an LM2917 and an SCR, which has the very nice side effect of being impossible to generate any mis-timed sparks, a highly desirable attribute for high output rotary engines. When the limit is reached by accelerating to the rev limit, the....

In this tutorial, I will show you how to write a very simple program. I am assuming that you have written ladder logic before, and that you have some basic familiarity with microcontrollers, but that you have never used LDmicro. If you don`t know very much....

555 Timers are very fun to encounter and experiment with. They can be used as a timer and can be set to a certain frequency. In Part II of Electronic Project I, we created a circuit that would get an LED to flash. This time we are going to add a speaker so....

Its a simple fly back tester, I believe you can built it, i use this circuit to test all of high freq transformer like SMPS transformer or fly back, this circuit is an astable multivibrator with about 90Khz freq, 12 vdc as vcc. To check SMPS transformer or....

I have a Power Factor Correction board that was taken from an old Sun Microsystem Spark450 power supply p/n 300-1359-xx. It has everything I need for a 650 watt inverter. The entire PFC circuit is not detailed in this image. The only part of the circuit I....

I am a mechanical engineering student, and for a part of my design project I wish to use a timer as so the motor switches off about 40-50 seconds after activation. The 555 timer chip is a rectangle with a indented o on the top, i assumed this was equivalent....

Here is a simple circuit diagram I think will work for the charger. I already have the transformer, two SCRs, maybe the capacitor, heat sink, and a case to mount it all in. If you go for lead- acid batteries and forget the SCR`s, or put them in a circuits....
