Dear Rusty, all you've to do is make a subinterval division of your operating temperature range, in my case 10 iunterval was fine to reach a maximum error less than 1 %. My setup was a simply 5 V reference with a 1% resistor in series with the thermistor then the intermediate point between the...

For a my old design I've to retrieve the temperature from a NTC thermistor using a PIC microcontroller. I've solved it by sampling the NTC characteristics in several point (10 interval from 0 to 150 °C) and after that I've calculated the linear approximation coefficient for every interval. To...

Hehe you're right, I can put the book at 100meter and the release it and use the potential stored into the book to move the car, of course the final efficiency is very little because I've also to take in account the work that I've did to put the book at 100 m. Then what can be a logical...

@thaddeus Thanks for your reply, well, take a look at my previous email, my think is how I can estimate the total energy that can be sourced from the Troy Reed magnetic motor and if this solution is really or just another joke. Regards Grinch

I'm totally agree with you, but the point is if the energy that can be feed from the magnet should be able to build a real working magnet motor and if this is true how I can estimate the life of this system. To see a case that I'd like to investigate take a look at the attached paper and also...

Dear all, from some time I'm reading about this (may be) new type of technology useful to produce clean energy. You Tube have plenty of video about this type of motor but I've not found anywere a theoretical explanation about how this type of motor is able to work. Then I like to know what is...

Dear all, I've also started in learing VHDL, at first I've do some simulation of vhdl code by using Modelsim, after that I've do the synthesis stage by means of synplify (with this tool you can also look at the RTL view to see the equivalent gate level transposition of your VHDL code), after...

Dear Crosson, first we like to thank you for your time, after that your phrase give me some comfort: I'm totally agree with you, the power extracted from the wind is just a theoretical calculation, in other word I'll expect to extract a maximum power equal to the calculated one if I'm able to...

I'm sorry to boring again, could someone take a look at my question? Tnx Grinch

Dear all, I'm just doing some thinking around the maximum theoretical power that can be extracted from wind by using a wind plant. Derivation of the power inside a block of wind is not difficult then I'll simply report some consideration regarding this subject (look at the attached paper for...

Well, I've started the design. At now my idea was set a simple circuit into the Maxwell Circuit Editor and then make the magnetics componenents into the Maxwell 3D simulation evironment. I've do this step: 1. draw the circuit 2. set the component name 3. export the circuit netlist I've...

As useful reading I'd like also to suggest this book: "VHDL", Third edition, Douglas Perry ISBN: 0-07-049436-3 McGraw-Hill may be there is a new edition, I do't know, make a check for this. Cheers Grinch

Dear all, I'm a new user and I like to exchange information about the use of this tool. From my point of view tool using should be done by suitable tutorial or guide but for this type of software I was unable to find anything useful in that sense. I'm a electronic engineer and like to know...
