C Sharp Development 101 – A Tutorial Series

In this tutorial series we are going to look at C# Development using the Visual Studio 2010 Express editions.  This will take you from the basics of installing Visual Studio 2010 Express, to the Object Oriented Programming style associated with C# and other languages, dabble in some database access (Access & SQL Server Express) and finally, design a project that will pull all of our knowledge together into a final solution.

The Spindicator

oooh shiny

[Harvey] wrote in to share the Spindicator with us. The spindicator is a hard drive activity activity indicator built in a ring to resemble a dekatron. Using the pulses from the hard drive activity LED, [Harvey] tested several different methods of interpreting that data for display. The final version, negative edge triggered with a lowpass filter can be seen after the break.  It is nice and smooth and vaguely reminiscent of many programs’ loading screens.

He has pictures and tons of detail on the project including videos of previous versions that acted quite erratically.

EEVblog dissects a kindle 3

guts!

[Dave] over at the EEVblog did a review of the kindle 3 recently, but never got to the good stuff, the guts.  He is now rectifying this with a full video dissection of the eReader. Full of details on how to open it up as well as specifics on the internals, this is a fun video to watch. One thing that caught our attention was the RFID tag on the inside of the case.  It is probably for inventory tracking, but we can’t help but have a few tinfoil hat type thoughts. You can watch the video after the break.

Controlling the power of a flash with a tv remote

For those who do fancy photography, setting up the lighting ends up being one of the larger tasks of each session. There are flashes out there that can be controlled via a remote control to help ease the process, but they can cost a considerable amount more. [Dsvilko] shares with us a fairly simple circuit that allows you to use a tv remote to control your flash. He’s using a picaxe 08m and he states that before this project, he had never messed with microcontrollers. We say great job on your first microcontroller project. You can catch a video of it in action after the break.
