Halliday, Welcome to this forum. Are we talking communication or cooking?

No bother at all Micke, here is some additional info: http://goncom.co.kr/pdf/abco/2_02.pdf http://www.elexp.com/t_induct.htm http://www.coilcraft.com/?source=looksmart http://users.pandora.be/educypedia/electronics/coilsrelay.htm Please keep us posted on the outcome of your project!

Kain, If you refer to the schematic I made I have marked it

Well, if it has a name you can by one! ;D

Sorry for butting in like this but I must add to this that the pin connections is written on the cap. Look at the top picture

Sorry huzefa, but you are in the wrong department!

The TL431B can be viewed here: http://www.wb-power.com/bbs/u/20/1093886118.pdf If you f ex change R6 to 15k the output voltage will be 5Volts. Just below the message window is the Attach window, here you can add your picture.

Last chance, go here and ask for a schematic: http://www.wimtv.be/techniforum/index.php you have to register, but its free. Good Luck!

Oh yes, you can measure inductors if you have the equipment for if. There are some multimeters that have ranges for inductors. I suggest you take a look here: http://www.elfa.se/en/ and chose

Under normal circumstances I have no problems reading peoples minds when someone is visualising stuff but in this case the distance between us is too big. ;D ;D OK, so constant voltage but with the option to be able to change it. We have to establish in which range you like to change the voltage f ex (12

This document (page 11) contains an application for a Minitel.pdf

OK, page 29 to page 59 I get it. Are you planning to make a PSU without a

John, It should be possible to post up to 3000kb! "Allowed file types: txt,jpg,gif,pdf,mpg,png,zip Maximum attachment size allowed: 3000 KB "

Kumar, Yes you can raise the voltage to more than 24 volts but there is a very low current output from the ICL7660/62. The PC PSU is a SMPS. 7A is not a problem. Yes negative supply is also available.

Hi Newguy, I don

Dazza, There is nothing wrong with looking ahead, but it

Dazza, I had a long look at the PWM circuit and there are a couple of things I can

Kumar, You must use a motor rated for the load in your application then you can stop it just by stopping the pulses. PWM is used for other kinds of motors. If you exceed the holding torque by applying more current you will damage the motor in a very short time. It is possible to use some kind of mechanical brake to hold the shaft but this will complicate the construction.

Hi Rhonn, I can

It doesn

What is the application? In what kind of equipment is the TEA2018A used?

Mud is the word my friend, ;D on some points I can see what you are aiming for. If you want an indication that the engine has started just use the charge indicator light. This takes no sophisticated electronics to achieve. When the ignition is turned on (see picture) the charge indicator lamp gets positive from the battery and negative through the alternator (not charging). When the engine is

Emiliano, 1.Yes bigger filter capacitors will improve the ripple rejection but so will a series inductor (choke). 2.The inrush current will increase with bigger caps so a bigger bridge is necessary. 3 It is possible to use one half of the transformer for a
