Welcome to Clifton Laboratories, the page of Jack Smith, K8ZOA, author of Programming the PIC Microcontroller with MBasic. This site documents my past and present projects in the worlds of PIC microcontrollers and amateur radio.

Click on any of the images below to learn more about it, or follow the navigation links to the left.

And you can search my site via the search box at the top of this page.


The updates page is my daily (more or less) journal of what I'm up to. It's the best starting point to learn what's new at Clifton Laboratories.

The Current Products page links to the kits I have available for sale.

Visit Larry, N8LP's page to see his PIC Microntroller ham radio projects I've known Larry since we were both college age ham operators in suburban Detroit in the 1960's. You'll like his projects. Here’s his latest project, the LP100 wattmeter, a state-of-the-art HF wattmeter kit, with real-time R+jX impedance display as well as power and SWR.
