FPGAs For MCU Guys

by Max Maxfield @ eeweb.com: A little while ago, it struck me that I was getting tired of explaining what FPGAs are and how they work their magic to those of my chums who — thus far — have worked only with microcontrollers (MCUs), so I decided to write a three-part mini-series of...

Amplifier requires no dc bias

john guy @ edn.com writes: Intrinsically capacitive transducers and other high-impedance signal sources usually require ac coupling and a buffer amplifier to condition the signal for further processing. Buffers take many forms, but most of them compromise signal quality through the...

Simple negative resistance oscillators

Bob tipped us about a simple oscillator that uses negative resistance: Normally -according to the Ohm's law- when the applied voltage is increasing, the current is increasing too, however some components can break this law. When the voltage increases, current decreases. This is...

Latching Relay Module

govindanunni@ instructables.com has build a latching relay module using 555 timer IC that is also able to interfaced to a microcontroller. In this instructable I will show you how to use a non-latching relay as a latching bistable relay by designing a simple electronic module which...

The Making of a Cooled CMOS Camera

landingfield.wordpress.com shows us their progress on how to make a cooled CMOS camera able to be used for astrophotography. In the last post, I uncovered a bug in the Vivado implementation which accidently removes the DIFF_TERM from my input buffer. With that problem solved, I...

LC-04 4 Channel Logic Converter 3.3V – 5.0V

If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The LC-04 bi-directional logic level converter is a small device that safely steps down 5V signal to 3.3V and steps up 3.3V to 5V at the same time. In this instructable, mybotic explained...
