One point on the above, the FSW process is actually quite a good process to use and similar to welding. I worked on the Eclipse project which was really the first Aerospace application of FSW and the welds (if you can really call them that) were VERY clean. No HAZ to worry about because the...
... over my head? Understatement :)
As I was burning my fingers, I figured that turning on the IRF might be the issue and tried the same setup using a TC1427 inbetween the 74HCT175 and the IRFZ44 with the driver's Vdd at 10V. But still the same problem. I checked the gate voltage on my DSO and...
Ok... some time passed and I actually got the chance to work on this a bit more. So I've added a 74HCT175 flip flop and 10kHz square wave to the F/F Clock and Master Reset inputs (I might try adding a higher freqency to the clock and a lower one to the MR). I then ran the output from the...
Thanks... I guess you nailed the reason why this won't work like this. The LM324 (yes, that's what I meant) has a fairly low frequency response.
Now... what if I added a Schmitt trigger gate (like the 74AC14, and reversing the + and - inputs on the LM324)? That should get the switching times...
The idea behind the opamp is really to use it a bit like a PWM circuit. The Op Amp is being used as a comparator here, not as an amplifier. Take a look at the attached images of the circuit (parts aren't exactly what I'm using but fairly close) and plot that I got from LTSpice (green is the...
I'm working with a DC motor controller that requires an additional current limiting circuit. The value of the current doesn't have to be very exact as long as I can control it so it doesn't drastically overrun the specs (5A, 1ohm, 3mH).
What I have thought of is a opamp that has a potentiometer...
If I may throw in my 2cents on this, it appears that the problem is indeed somewhat simplified in that radiation seems to be ignored even though this is a very large pool of oil which is likely to have a high emissivity/absorption.
As a second point, it makes sense to look at the applicability...
