Linux Fu: Python GUIs for Command Line Programs (Almost) Instantly

Not every programmer likes creating GUI code. Most hacker types don’t mind a command line interface, but very few ordinary users appreciate them. However, if you write command line programs in Python, Gooey can help. By leveraging some Python features and a common Python idiom, you can convert a command …read more

Qt Arrives For Small Computers

There was a time when writing embedded systems meant never having to deal with graphical user interfaces, and spending long hours trying to free up a dozen bytes of ROM to add a feature. Nowadays, an embedded system is likely to have a screen and what would have been a …read more

ESP32 Gets Advance Windowed Apps Using This VGA GUI Library

We featured [Fabrizio Di Vittorio]’s FabGL library for the ESP32 back in April of this year. This library allows VGA output using a simple resistor based DAC (3 resistors for 8 colors; 6 resistors for 64 colors), and includes functions for PS/2 mouse and keyboard input, a graphics library, and …read more

The Mother of All Demos, 50 Years On

If you’re like me, chances are pretty good that you’ve been taught that all the elements of the modern computer user interface — programs running in windows, menus, icons, WYSIWYG editing of text documents, and of course, the venerable computer mouse — descended from the hallowed halls of the Xerox Corporation’s Palo Alto Research Center in the early 1970s. And it’s certainly true that PARC developed these technologies and more, including the laser printer and object-oriented programming, all of which would grace first the workplaces of the world and later the homes of everyday people.

But none of these technologies …read more

Arduino Provides Hands-Free Focus for Digital Inspection Scope

With surface-mount technology pushing the size of components ever smaller, even the most eagle-eyed among us needs some kind of optical assistance to do PCB work. Lots of microscopes have digital cameras too, which can be a big help – unless the camera fights you.

Faced with a camera whose idea of autofocus targets on didn’t quite coincide with his, [Scott M. Baker] took matters into his own hands – foot, actually – by replacing mouse inputs to the camera with an outboard controller. His particular camera’s autofocus can be turned off, but only via mouse clicks on the camera’s …read more
