    Engineering Help on simulating a circuit - First attempt didn't work

    I did the circuit in LTSPICE, but here's the schematic of my circuit, which the professor said looks good: http://l.bitcasa.com/X-bpPMWt But here is the error dialog that pops up whenever I try to run the simulation: Circuit: * C:\Users\user\Documents\waterlevelcontrollercircuit.asc Error...

    Engineering Help on simulating a circuit - First attempt didn't work

    I am working with a spice model for NE555, but it looks like this: http://en.wikipedia.org/wiki/File:555_Pinout.svg Instead of this: http://www.circuitstoday.com/wp-content/uploads/2011/04/water-level-controller-circuit.pngI can't find a NE555 spice model timer with that specific arrangement...

    Engineering Help on simulating a circuit - First attempt didn't work

    The simulation software only had an IC 555 timer that had 7 outputs, and they weren't even numbered, whereas the example schematic had 8 outputs and were numbers. Can you recommend me a circuit simulation software that can do just that? Why 7 and not 8? Why the strange th, tr, ctl, labels? Why...

    Finding Thevenin Voltage w/ Voltage Sources & Zener Diode

    http://l.bitcasa.com/h1JexqbW Refreshed the page, solved the equation with different variables using the same methods above, including Vth - Rth*Id - Vz, and it still did not work and it gave me a wrong answer. It's practically mocking me. Something is wrong with the computer system this...

    Finding Thevenin Voltage w/ Voltage Sources & Zener Diode

    http://l.bitcasa.com/7wz_SYeM I've tried solving for it again, but to no avail. Must be something wrong with the computer system as I may have been on the problem for too long.
