Oscilloscope XY Outputs are Working!

Using two PWM outputs and using a couple of simple RC circuits on the board, we have managed to get the XY outputs working well enough to display on any oscilloscope! I now feel that the hardware is feature-complete!

PC Fan - One-to-Many

Sorry that it has been so long since our last post. I have been out on vacation for a bit with some family and am just getting back into the swing.

PC Fan Controller

I recently wished to add a fan to my PC and I realized that I only …

SolidWorks/Inkscape/Ponoko

Intro

In this article, I am going to guide you through an easy way to transfer your SolidWorks design into Inkscape in preparation for laser cutting. There is already some information out there, but the guides appear incomplete, so I'm tossing in my $0.02.

This will not be a …

Modeling Software

I am a big fan of SolidWorks as a 3D design package. I am completely untrained, yet with a few hours of practice, anyone can pick up the software and do something useful. After a while, you can start to do some really nice things with it!

Repository Adjustments

Design Refinement

There have been a couple more patch wires and a bit of scope creep, but no show-stoppers and a fair amount of added functionality.

Since the last post, we have:

  • Added a three-terminal mode which …

Prototype tkinter frame layout

Making Progress on the GUI

As you can see, the visualization tool is becoming more mature. We have taken the visualization scaffolding developed in the last post and added a few elements to each frame. It is amazing what a few buttons and menus will do for the looks of …

Vision

For some time, I have been working in small portions on Dispatch as a serial library for the curve tracer. Initially, I thought that the serial library would be limited in scope to that particular project, but I began to see that the library could, potentially, be very useful …

Python Logo

The title pretty much says it all! I have put my first package on PyPI! This is something that I have been curious about for quite some time, but never had the need to do until this project.

I had to rename the python port to "serialdispatch" since "pydispatch" was …
