Ok I will

Many thanks

I guess what its sayning that the current out is the sum of current in and since my trasistor choise has nothing to do with the currents flowing into it then the only thing that matters is whether is a NPN or PNP as long as its rated to survive the currents in the system. Br, Peter

I personally don't see any reason why they should not be interchangable and I guess its only a plus that my Continuous Collector Currents are rated higher than the ones in the sketch as I suppose it means that they can handle more current without the magic smoke.. Br, Peter

Hi Borek Thanks for the reference, but I don't feel that it answers my question specific to the circuit that I'm looking at. Br, Peter

No, the BC327 is a PNP and the other a NPN

Hi, I'm about to build an autopilot remote for my boat, manual found here: http://www3.sympatico.ca/ericn/Files/Other/DIY Autohelm ST4000.pdf In the scheme I need to use two transisters, a 2N4402 (PNP) and a 2N4400 (NPN) as illustrated here: As I don't have these transisters can I use a...

So you are saying that the fit depends only on the number of points in a variable, and not on the number of variables nor the variable dependencies - that sounds pretty strange. Doesn't the N-1 rule apply to only a single variable with N values? The purpose of the program would be to discover...

Hi all I have a lot of data, and was thinking if there exists a program that will apply a type of brute force regression tool to basically try any thinkable combination of variables and mathematical expressions to minimize the error between Y and Y_predicted. The data [(x1 vs Y) (x2 vs Y)...

So something that I am not sure I understand - and that the work performed... If the kite moves nearly infinitely slow over 100 meter (case 0), then it will have performed 1007x100 Joule but if it moves at the speed of the wind it will have performed ZERO Joule due to the force being zero. Does...

Yeah that's what I figured. That means that I need to move towards some type of kite design that loops in figures 8's as there are a ton of people who already does. I guess I can't use the simple drag equation to calculate the force made by a kite.. I need to think about this.. Thanks a lot...

Hi all I have been looking at understanding power for a simple energy generation concept, and I think that I originally made an error in my calculations because I wasn't considering the relative velocities. So I basically generated the force made by a kite in static conditions, but if I need to...

So this problem is actually not that much for the sake of programming but more the solution of the analytical mathematical problem.. e.g. through graph theory... /Peter

by the way - it is written in Perl.

Ok thanks.. I don't have time to check it out right now but I will take a look at it later. If anyone should be interested this is how I solve the problem right now: First I create a list with programme seen below (maybe it is bad coding - I wrote in 10mins). When this programme has created...
