Buck Converter (DC-DC)

Alright! So hello everyone! Long time user, follower, commenter but first time iblest here! So for my first instructable I thought I'd share a recent simple project I made; a Buck Converter. Buck Converters are great! I use them all over the place in many of my nerdy, techy, geeky hobbiest projects. They also can commonly be referred to by other names, a DC-DC converter or a switching regulator. Essentially ...

The Advantages (and Drawbacks) of DC-to-DC Voltage Converters with Integrated Inductors

Such is the popularity of DC-to-DC voltage converters (“switching regulators”)––due to their high efficiency across wide input- and output-voltage ranges––that chip makers have focused a lot of research dollars on squeezing the essential components of the devices into modules. These modules typically include pulse-width-modulation (PWM) controllers and switching elements in a single, compact package, easing ...

Brushless DC (BLDC) motor with Arduino – Part 2. Circuit and Software

In this post I will describe the hardware and the software part of a project involving the use of BLDC (Brushless DC) motor salvaged from a broken XBox 360. This is a second installment in the series of posts related to Arduino and brushless DC motors. Please see the first part for a bit of info on the theory behind the commutation sequence. Once you understand the commutation sequence for the particular de ...

Improved Packaging and Control Generates Ultra-Fast DC/DC Converter

I wanted to have my personlal, nice looking Mediabox with a big display and remote control. I' ve been playing around with the Raspberry for a while so I decided this would be the platform of choice for this project. I' m actually a fan of Steampunk so I decided to use a Steampunkish style for the box. Features: Raspbmc user interface accessible via a 7" inbuilt display control via any IR remote control via ...
