Hi sinn What kind of engine is this? A stationary engine? A truck engine? Any other kind of engine? Can this coils be removed in a simple way(without dismantling the engine)? Are they electrically insulated? Is it glow plugs, found in some diesel engines? Questions are many, since you didn't supply us with enough information in the beginning, before you can get an answer. //Staigen

?? ??? :P Who? Me? What do you mean? A link to the project would be nice! ??? //Staigen

Hi novoid2003 I have been looking in my english/swedish dictionary for the word "domotics", but did not found anything. What does the word mean? //Staigen

Hi frt

Hi Oops, that was a BIG question, there are written a whole book about it, but i will try to show you. first we have to talk a little about the transformer, it have 40 V out only at its rated current, at low or none current output it have larger output voltage, that you have to measure. But lets say that you have a ideal transformer that have 40V output at all its current output up to its rated load, then the rectified and smothed output DC voltage is 40 times 1.41 = 56.4 minus the drop over the rectifier diodes, about 1.2 V = 55.2 Volts at zero current. But, due to the transformer is rising its output at low or zero output the voltage is going to be higher. Hope this solve some of your questions. //Staigen

Hi dummer, velcome to the forum, nice to have you here ;D The DC voltage is roughly the square root of 2 times higher, minus the voltage drop across the rectifier diodes, when properly smoothed, and without a load. //Staigen

Hi robinnnn, and welcome to this forum, nice to have you here ;D I hope you will be active, and ask a lot of questions and answer to others when there is something you know, and participate in a lot of discussions and have fun. ;D Now to your question You have the IBM part number, why dont you use that one?

Hi Xenobius I would buy an extra IDE controller(is it IDE?) !!! ;D //Staigen

Hi sssaaa How is it going with your FM-DXing? //Staigen

Hi again jc_lim3 If you switch out your 74HC365 to a SN74LS07 it will work, at the same time remove the PNP transistor and the 2.2K and 10K resistors. connect the 4.7K resistor between 12V and the output of SN74LS07, also connect this to the mosfet gate. Maybee you should have a pair of complemantary driving transistors between the SN74LS07 and the mosfet's gate to increase the switching speed. //Staigen

Hi jc_lim3 You haven't suplied us with enough information! ??? The smitt-trigger, what is that, is it feeded from an input of a microcontroller? ??? What is the output from the smitt-trigger? Open collector? Also, the gate cap of the mosfet makes it switch slow. //Staigen

Oh, sorry, i read your post wrong, excuse me //Staigen

Hi Just post it, we are waiting! Get it elswere then! //Staigen

I also meant the essay above that Thanks again //Staigen

Hi Cryonic Thank you for sharing your nice thoughts I also like the warmth sound of a tube amp I have some tubes too, about 1000-1500 i belive Thanks again //Staigen

Hi Mr Heckles Good to hear that it works! Have a nice weekend, and good luck with your project! ;D //Staigen

Hi How did you make your -5Volt? //Staigen

Hi CPW, welcome to E-Labs Forum! ;D Nice to have you here! ;D ;D ;D //Staigen

Hi again Maybee there is an another solution after all, i didn't thought of it at first! The smitt-trigger- action resistors, do they need to be that big? Is it possible to rise them to, lets say, 100K or so? Than the current throu the switches are reduced, and also the voltage. Also an another possibillity come to my mind, that we take later. //Staigen

Hi The other method is called BFS and stands for Brute Force Solution, in other words, use a relay! At least for the malfunktion switches. A DPDT relay, together with the MAX333, or a 4PDT relay without the MAX333! Sorry

Hi again MrHeckles I belive i found one more error, the bases of your LED driving transistors is not protected, a reversed diode(1N4148 or similar) will help that! //Staigen

Hi MrHeckles I think i find one error, the pin number 5 of max333 shall be connected to a negative voltage, i

Hi Isn't that one similar to one of the amps here on this site? You cant use a simple telescope antenna for DX-ing! The circuit seems to be a working circuit, but aso check the cirquit, that is similar, here at E-Lab. And use a good antenna, else you won't be hearing anything! //Staigen

Hi I didn't get that! Are "limit" an input or outpt to the machine? Are "forward limit" an input or output to the macine? Are "reverse limit" an input or output to the macine? Maybee they should be ored or anded together? //Staigen
