    Wien bridge oscillator, diode stabilized, inconsistent amplitude b/w breadboard and PCB

    I am building a wien bridge oscillator using an LMV751 opa with an output frequency of 20khz. The breadboard version of the circuit above works perfectly, the output voltage is around 400mV pp at 20kHz. The breadboard version uses the SMD version of the LMV751 on a breakout board, and 1N4148...

    Scripting for Solidworks

    Hello, I am looking into how I can create scripts that would generate a text file which can then be read in by Solidworks to create the 3d model. I need to be able to create multiple iterations of a model (a solenoid winding) with different parameters (such as number of turns, wire thickness...

    Eliminate twisting from sweep around a helix

    Hello, I am having trouble modeling a multi-layered solenoid in solidworks. The issue arises when I sweep a sketch around a 3D curve that describes my helix. Although the sweep is done as “follow path” the shape is produced correctly for the first turn after which it starts sloping instead of...
