"This blog serves a narrow but illustrious audience: the photographically inclined electronics hobbyist. Yes folks, I’m going for the masses here:) Kidding aside, if the line above describes you, or even if it doesn’t but you find yourself having to illustrate an article here and there with an analog oscilloscope screenshot, then this article is for you."

"The Witness Camera is a combination of a VGA CMOS camera, a passive-infrared movement sensor, a 1 GB SD-card (or bigger), and an AVR Mega32 microcontroller implementing a solid-state time-lapse recorder. It is a compact, complete, self-contained surveillance system designed with home users in mind."

"The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight, but mostly because they look cool. "

"An interesting project has come up as a fund-raiser for BuildBrighton members – to “hack” some alarm clocks and modify their behaviour so that instead of playing a single sample when the alarm sounds, one of up to seven different sounds can be played."

"Capacitors are one of the most common passive electrical components that are extensively used in all kinds of electronic circuits. In this project, we will discuss a technique of building a digital capacitance meter using a PIC microcontroller. This project can measure capacitance values from 1 nF to 99 uF, with a resolution of 1 nF."

"I got all the basic Arduino tutorials running, so I decided to try my hand at something a little tougher: a digital “faradmeter”, ie capacitance-measurer."

Can you believe it? We’ve reached the final lesson of our new PyroEDU course: An Introduction To Microcontrollers. In this lesson we will take a look at what is AVR vs Arduino. Here’s an overview of the lesson:

"The arduino platform uses the AVR ATMEGA328 microcontroller to provide an awesome introduction to using microcontrollers, but there actually exists a world underneath arduino: let’s take a look at it. "

"In this tutorial we are going to drive a Single unipolar stepper motor using PIC18F4550 Microcontroller in various different stepping modes. The source code and Project files are free to download at the end of this page."

"All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. The focus was on low cost and use of materials easily accessible in the local market."

"I’ve been messing around with electronics lately (after all, that’s what I’m studying 😛 ), and this is the result! A 32×8 LED Matrix controlled by a PIC18F2550. You can click in the pictures for full size! At the end of the post there is a video of the screen running."
