Modification of a telescope motor controller for autoguiding
This page describes how I have modified my SkyWatcher dual axis EQ5/EQ4 motor controller to allow autoguiding through the parallel port from a PC. The modification allows the RA+, RA-, Dec+ and Dec- buttons to be activated from the PC via the parallel port and a cheap IC. I have tested the modification together with K3CCDTools v3. 0. 1 with good...
L297/298 Stepper Motor Controller
A better way to make a stepper motor controller is to make a printed circuit board, and then simply drop the components in. After making the PCB, placing the components and soldering them hardly takes any time at all, in contrast to the proto board which took a ton of time to make. Here`s a picture of the first stepper motor controller I made in...

Simple DC motor PWM speed control
The 555 Ic is wired as an astable and the frequency is constant and independent of the duty cycle, as the total resistance (R charge + R discharge, notice the diode) is constant and equal to 22Kohm (givin a frequency of about 1Khz, notice the hum). When the potentiomenter is all up, the Rcharge resistance is 1, 0 Kohm (the diode prevents the capaci

Ultrasonic distance finder circuit
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is measured. There are three main categories of distance measurement methods in use: a) By...

Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...
