The post comprehensively explains a simple electric match igniter circuit which can used for implementing a foolproof ignition of a series of Ematches through a microcontroller based control system. The idea was requested and explained by Mr. Jerry ShallisThe details may be understood by reading the following email discussion between Mr. Jerry and me. Hi Swagatam, I've just been looking at all the useful stuff on your site, and I'd start by thanking you for putting it all in the public domain. I.......

The LTC®4232 is an integrated solution for Hot Swap applications that allows a board to be safely inserted and removed from a live backplane. The part integrates a Hot Swap controller, power MOSFET and current sense resistor in a single package for small form factor applications. The LTC4232 provides separate inrush current control and a 10% accurate 5A current limit with foldback current limiting. The current limit threshold can be adjusted dynamically using an external pin. Additional feature.......

Variable lab power supply 0-24V / 4A, it is a laboratory power supply with output voltage continuously adjustable from 0 V to 24 V DC, remote voltage sense capability (Sense internal/external). It has output current limit which is continuously adjustable from 0. 04 A to 4 A and output current which can be limited continuously or output shut down (Limit/cut). Remote sensing mean.......

The final part of the lap timer build along is also the easiest part, involving only the IR Detector and an optional LED with current limiting resistors. The previous steps can be found in the project index section of RC Arduino -https://rcarduino.blogspot.com/p/project-index. htmlA good introduction to IR Detectors is provided on the Ada Fruit website here -https://learn. adafruit.com/ir-sensorTo start our build we need a small section of strip board and a set of three wires for power, ground a.......

Apologies for the long delay in posting. . . I'm currently writing 3 books and all of them seem to have had major chapters due on the same day this past week. . . and before you say "Are ya crazy?! 3 Books!" - I've got a fourth book that started yesterday and a fifth book looking to start in a month. It's insane. (Fortunately 2 of my current books are looking like they'll finish in the next week or two. . . but still. . . )I've also been working on a "very special project" - Arduino-related, of .......

As I've mentioned before, in my current job I get to visit and interact with many people and companies involved with product development; several every week. Most of these people/companies use history-based modeling of some kind as their primary design tool. As I walk through their processes and tool usage, I am continually amazed at how little value most companies get from their history based design tool and the resulting structured model, considering the level of investment that goes into the .......
