The key point is that there is no iteration as is usually done. All alignment methods I have seen rely on measuring, tweaking, measuring, tweaking, etc. There are many problems with this: for the DIYer it means expensive tools or settling the suspension....

Cool little FM transmitter. Suitable for study purposes, you can use the RF part of this transmitter easily for your projects. However, unless you know how to build a serial data link and connect this LPFM transmitter to a PC or a microcontroller, you won`t....

Several years ago a colleague suggested that I should be using PICs for my hobby, which then was amateur television. I spent many hours developing and experimenting with video mixers, faders and effects (FX) units, and all this was done sing analogue and....
-
I designed this project for another boy who had a much bigger box of electronic scrap than me so he supplied most of the bits for it. I made it in few evenings besides doing my homework. We wanted it to play a bit of a tune so we looked through the Maplin....
-
All that remains now is for the code to be `, compiled and converted to a HEX file that the PIC can understand. This is achieved easily with the PIC compiler that comes with the PICBASIC package. The PIC is programmed with any of the parallel or serial port....

As I carry out a lot of repairs on C. B. and audio equipment, I need a variable power supply with very good current limiting and protection. The circuit I designed for this purpose is shown in the diagram below. This power unit will deliver a current from....

CMOS logic integrated circuits are extremely versatile devices which are used a great deal in modern electronic circuits. Like any logic circuits, those which employ CMOS devices can be difficult to test using an ordinary multi-meter as both static and....

Then iron the printed layout at minimum heat until the ink sticks to the PCB. It may take more than an hour to finish. Remove the transparent paper afterwards. 6) After that, submerge the PCB with Ferric Chloride Liquid until the expose copper is totally....

In order that the MonomeSerial software `sees` the monome clone, it`s necessary to change the serial number of the arduino`s EEPROM to resemble the serial number of a real monome. I successfully followed Melka`s instructions that have been posted on the....

The study of electricity revolves around a few common terms that describe the behavior of electrical charge. Electrical charge and its associated phenomena are a fundamental part of the world that we live in. The understanding and use of electricity is....

My major project over the last few months has been the construction of a small Tesla coil, having wanted to make one for many years now. My first experience was at a demo day at UNSW over a decade ago, and since then I`ve always had a bit of a fascination....

I just about the circuit you made. what kind of IC is 4029N & 4511N Is it a diver/decoder I tried to research on the datasheet but it cannot give exact specification. ..

Got a free treadmill. Here`s the diagram that came with it. Sorry about the size. I have a question about a board that is up in the console. It has four readouts, time, speed, distance and calories. Don`t need those. It also has a membrane panel with four....

I am interested in building a solid state control for my Warn 8274 self recovery winch. The current control scheme uses 4 constant duty 200 amp solenoids. 2 switched in parallel to connect the field 1 terminal on the motor to the armature for power in, and....

My question is what part of the circuit controls the lowest rpm that can be achieved with your circuit? I`m getting a range of 1400-3700 rpm on my motor with your circuit and want to tinker it a little bit for a slightly lower rpm...

My JD mower, for quite awhile now, has been very erratic at starting. Sometimes the starter will activate, but more often it will not. Yet after a long wait it will sometimes start. I found a tip on the internet, recommending puting a relay in the circuit.....

BD237 datasheet, .Selling leads from all over the world, ChinaICMart is the world`s biggest IC trading marketplace on the internet. We offer finest suppliers for BD237, you can also download the datasheet for BD237...

Look for the OSCCON register in the data sheet (as of this edit, page 19). This register, among other things, controls the speed of the internal clock. Upon startup, the processor runs at 31 kHz (way too slow. ) Using OSCCON, we can increase the speed to....

The concept of an AC model for the triode is presented and the equivalent circuit technique is described. Theoretical calculations for amplifier gain and frequency response are derived and compared to simulation results in the SPICE3 environment where good....
