Join Collin Cunningham as he explores the oh-so-tiny world of surface mount electronics. Follow along as he constructs what may be the world’s smallest phototheremin all in super-macro detail – plus learn why adhesive poster putty is so darn useful.
Learn the basics of controlling a grid of LEDs, then use one as a miniature game machine and more, as Collin Cunningham takes a look inside the LED Matrix.
The deceptively simple wire coil that proves incredibly useful in the world of electronics – the inductor’s ability to store energy in an electromagnetic field is the key to making transformers, electromagnets, and many more components. It truly is an awesome device!

A brief introduction to the tech that makes it possible for today’s electronics to do so much in very little space — the Integrated Circuit
On uC Hobby, they took apart an old desk phone, scavenged it for parts, and wrote up what they found: The easiest way I have found with modern technology to identify parts is to type all of the markings on the part into a Google search, and refine your search from there. If you then […]
Dave Fowler, of uC Hobby, sent us a link to this java app for determining resistor code values. There are a lot of these resistor ID tools floating around, in different formats — it’s nice to have the option to use which one works best for you and your circumstances (for instance, I don’t have […]
