ViewSonic22 " LCD with DVD player

Image
We still haven't been able to shake the ViewSonic dragon from our memory, but we're attempting to move on with our lives by directing our attention (however briefly) to the N2201w. This so-called "3-in-1" LCD TV packs a 22-inch 1,680 x 1,050 resolution panel, a 5-millisecond response time, 1,000:1 contrast ratio and a built-in NTSC / ATSC / QAM TV tuner. You'll also find an integrated DVD player and an HDMI port, and just to prove it really is multifaceted, there's a PC input to boot. No telling if the picture quality is anything to write home about, but the $429 price tag sure is palatable.

We've been waiting ever patiently for this to get official, and at long last, that Project Projector we saw leaked in July has been revealed. Formally christened the M109S, this 0.8-pound beamer arrives with a native 858 x 600 resolution, a projection distance of up to 94.5-inches and a mercury-free LED light source that lasts up to four years. Moreover, it packs the ability to suck power from a Latitude or Vostro AC adapter if you're caught in a pinch, and yes, it's available today for $499 in the United States. As for the rest of the world, you wait.

Make PCB at home :Low cost way

Image
In india, a DIY enthusiast faces one common problem that is to get the PCB done. There are lot of firms that manufacture PCB but the ordered quantity required is very high else order value should be minimum 5 to 6k . This poses a big problem and also ordering 100/200 pcs of pcb for a experimental project is meaningless. Here I present a guide that will help to fabricate PCBs in quantities of 1-2 pcs at home . ~IRON-ON PCB FABRICATION~ It is based on the fact: "Laser printers and photocopiers use plastic toner, not ink, to draw images. Toner is the black powder that ends up on your clothes and desk when replacing the printer cartridge. Being plastics, toner is resistant to etching solutions used for making PCBs - if only you could get it on copper!"

what is Hot plug in Linux

Just like windows Plug n Play , "Hotplugging" today is mainly "dispatch device events from the kernel to userland" and not only loading modules. If you only need to autoload modules, you can do this with one damn simple generic binary or script pluggged into /sbin/hotplug. But if you need to hook into event to notify system daemons or run programs for specific devices, forget the whole old hotplug package and /sbin/hotplug and run the udev daemon and specify rules to plug into the device events.

Writing a script to simulate the hot plug for linux USB

Writing a script to simulate the hot plug for linux USB Here is a script you can use ... Give name myusbmonitor # to run $>myusbmonitor 1 / $>myusbmonitor 0 #!/bin/sh #Description: A prototype script to demonstrate insertion/removal any usb device \ using udev frame work of linux # #Note: Use this script when you have following lines to \ /etc/udev/rules.d/50-udev.rules # # ##Added by Manjunathan Padua ACTION=="add", SUBSYSTEM=="usb_device", RUN+="/sbin/myusbmonitor 0" ACTION=="remove", SUBSYSTEM=="usb_device", RUN+="/sbin/myusbmonitor 1" # if [ $1 -eq "0" ]; then echo "usb was inserted into the PC " >> /tmp/usb ; #log the usb found event else echo "usb was removed from the PC" >> /tmp/usb ; #log the usb removal event fi

Linux system programming : linux kernel concurrency

The main difference of kernel threads with user space processes is concurrency ! user space programs run from the beginning to the end, without any need to worry about what else might be happening to. But for kernel drivers ,naturally, Linux systems run multiple processes, more than one of which can be trying to use your driver at the same time. Most devices are capable of interrupting the processor; interrupt handlers run asynchronously and can be invoked at the same time. Because of this Linux kernel code, including driver code, must be reentrant—it must be capable of running in more than one context at the same time.

Linux system programming : Differences between User Space and Kernel Space

Here we list a few : >userspace :the processor regulates direct access to hardware and unauthorized access to memory. >kernel space : access to the hardware is possible directly , depends upon previledge levels > both have different address space >user spece request is translaetd to a system call that lets the processor to switch mode to enter the kernel space , here kernel threads handle the execution > exceptions in user space are less fatal .. while kenel space exceptions will kill the process >kernel space supports module load /unload
