    I've got "wave (2).asc" and I've got "wave (2)_VeeCAD_v2.pdf" and I'm using VeeCAD for CAD (veecad.com/downloads.html -- free version available, full version got some features, most notably skew components/wire vs just horizontal/vertical)
    so remove the .txt on the "wave (2)_VeeCAD_v2.per.txt" if you wanna boot it in VeeCAD,

    otherwise


    ANY help please

    What the circuit designed to do? What's the missing IC? Are we suppose to get out the crystal ball?

    huh!? it's a theremin designed to produce a fart sound, I'm building it for my niece, she's 6, hours of farting fun! On my side I've got 555 ICs in the .per .pdf and .asc file NE555, what do you mean by missing IC?

    Since I didn't want to load the program, I only looked at the pdf file. The breadboard layout doesn't list the IC.

    OK, sorry I didn't label the IC, but it's labelled in the LTspice .asc and really why do you need that information, we modelled the circuit in LTspice, it works, I only need a breadboard layout that works, because I tried 3 times on v1, (didn't think to version it) and once on v2 and I can't get the .asc file to be the same as the breadboard layout, so really I only need help placing the components on a breadboard circuit that works, help is straight up ?"this wire should go there on not here"? The circuit is sound, only porting it to the breadboard isn't.

    OK, I thought it was a theremin, it might not be, that's beside the point. This circuit is simulated to do what it should: fart no problem with the design, I can't draw a breadboard layout that works, I'm almost physically tired from trying, desperate would be the word

    Could you post a schematic -- i.e., a screen shot of the schematic as opposed to the design file for a particular simulator package?

    How do you know that it works based on simulation? How do you know the waveform displayed sounds like a fart? Did you get the waveform data into a sound file that you could play? If so, how did you do that (I'm curious, though writing a program to translate it wouldn't be too tough).

    What is the highest frequency component in any of your signals?

    Post a screenshot of your schematic.

    Here is what I could determine from you pdf breadboard pictorial diagram .... I'll wait on your screenshot to see how close I came. The software is pebble, if anyone is interested.

    LTspice simulates waveform aswell, so I know what it sounds like (SPICE directive ".wave out.wav 16 44100 V(out)")

    EDIT: sorry for the late reply, It was sleepy time ;-)

    How familiar are you with a breadboard? If this is your first time using one, maybe this tutorial will help. Of particular interest to me is the section on the anatomy of a breadboard, but read the entire article. Perhaps this will help you breadboard a working version of your schematic.

    I've done maybe 10 boards, will read after 18h00 SAST (GMT+2)

    yep, as I suspected, the pictorial needs work.

    I highly doubt there are too many humans that can fart for an infinite number of seconds.
