This is continued from my previous post about using Inkscape to draw pcb and front panel designs.
When I last left you, I had created a multi-layered inkscape drawing that had front and back designs for the PCB along with a drill pattern for the panel. First I’m going to get out my Toner Transfer paper. This is thick stock paper with a water soluble coating. It allows you to fuse a printed image to a surface and then remove the paper when submerged in water. The stuff is a little pricey at about $1 a page, but it’s well worth it for making good clean transfers. I’m using my home laser printer to make the PCB transfer.
I start the print job and manually feed the Toner Transfer paper. The print out looks good! Print Resist Directly on PCB with Modified Ink Jet Printer. Ryan Pourcillie hacked his inkjet printer to have a straight through path so that he could print resist directly onto a copper clad board to make a custom PCB.
He then uses special ink in the printer which can act as a resist since the normal ink jet ink would just be eaten away in the etchant tank. Converting an Inkjet Printer to Print PCBs : Removing the Print Head Assembly. The next step is where you roll up your sleeves and start the cutting and modifying process.
It's also the step where you need to pay attention to what you're doing as you could seriously injure yourself and/or ruin your printer modification completely. As such you should be wearing safety glasses or goggles during the cutting process and keep your hands away from the cutting disc. Also for those unfamiliar with using a Dremel tool when you cut through the metal sections of the printer body you will create a rain of sparks and small flakes of sharp metal. As I said before be careful and wear safety glasses, you don't want any of this stuff in your eyes.
Modifying an Epson printer to print PCBs-Engineering/Technical- PCBway. Here I'll post step by step modification on my Epson S22/T22 to a PCB printer.Below is a Epson S22/T22:Taking bits apart: Power Module off: Pull the pins/plug off the board, then pull the power module out.
I put 2 washers under each point where the screws are, to raise the X-rail or the head rail, 1 washer = 1.04mm... I got an error and my guess was that I raised the rail a bit too high, so I changed the washers to a thinner one, 1 washer = 0.75mm. Some people would raise the printer Head rest mechanism the same height as the washers, but I'm not doing that. Just few minutes ago I was trying out Epson printing options to get the best result of black ink on to the copper clad board, started by choosing Quality option---> photo the paper option--->Epson Photo--->print, then back to paper option--> Epson Glossy-->print and so on. Pcb-pool PCB Printer [shackspace wiki] Epson Stylus Photo R800 Reset-chip mod - you can ignore empty-ink warnings All ink cartridges except for the black ones are empty Special heat-drying ink for use as etch resist (Tritron N-GEN XN 00070 Black, Info) Primer (PPA5, CATS+) PPA5 is 95% Ethanol with some chemicals to make the ink stick.
Primers are made specifically for Tritron ink. Alternatively use a mix of Ethanol with a pinch of Glycerin. Adjust workflow: do not swipe but dab alternative primer onto board. 3DMegaAutomations: Direct PCB Printer - T22.

Project Selection. Project selection is the first important part of project portfolio management.
Who is responsible for the selection and review of projects? The responsibility is with the leadership team of the organization. Typically, they establish a steering committee that overlooks the process of selecting projects, including project monitoring, and directly reporting to the CEO – if the CEO is not a member of that steering committee already. Application sample – competency based questions. Competency based questions can sound a little scary as they are so involved.
However, they are just a way for employers to make sure you know what you’re talking about – complete with detailed explanations. Make sure that you answer these questions properly and you’ll be in with a great chance of getting an interview! Q: Describe a situation where you have worked as part of a team to achieve something.

Streaming over LAN with local RTMP server. Flash-based audio and video communication. How to do two-party video call? You can do live video call by having two instances of VideoIO application, one capturing live camera view and microphone audio as local stream to the media server, and other playing the video and audio of the remote stream from the media server. Please see How to work with media server? On details of installing and configuring a media server. For illustrations in this section we assume that you have a media server running on 188.8.131.52 and that has an application called myapp which allows you to do live media stream. Thus, your media server application should be reachable at " In real deployment you will use the real host name or IP address of your media server. The src property of the VideoIO application can be set to enable the local (publish) or remote (play) mode.
The user interface will typically have two VideoIO instances - one for local video and other for remote video. The following user interface embeds two VideoIO instances.

This tutorial will explain how to use the popular video conferencing software Skype(tm) in order to stream or broadcast a VGA, DVI, or HDMI video source signal to a remote viewer. Advantages of using Skype include ease of use and accessibility (multi-platform, including mobile devices). Furthermore, Skype is free and supports 2-way audio and video communication. Thus, you can see and hear feedback from the viewer. At the same time, Skype has a disadvantage - sharing screens is no longer free, and has performance trade offs when the same computer is screen scrapping and encoding audio-video for Skype. With this architecture, the quality of video may suffer and is completely out of the user's control.
Ltd - Applications - PC Images over IP. Full High Definition (HD) 1080P Video, Audio and PC graphics over IP This article describes the benefits of sending Full HD 1920 x 1080 Video and PC graphics at 1280 x 1024 over an IP link, compared to traditional analogue cable methods. This paper shows 3 practical examples of sending images either from cameras or PC monitors at very high quality and frame rates over a standard 10/100 ethernet IP Network.As more and more large or small users of CCTV and PC based security systems wish to integrate , distribute or centralise monitoring, Video over IP appears an ideal solution. Video quality has until recently been limited to VGA or PAL/NTSC which has been inadequate to send todays high graphics content found on Personal Computer screens.

A recommended practices document is being created covering interconnection of professional audio equipment. Many shield-wiring practices exist in the audio industry today. Over the years, the declining cost of professional audio equipment has facilitated its use in more and more home studio environments.

Microsoft sent me a RoundTable system for review. I figured I may as well install it in one of TMC's two conference rooms to have some "real world" testing scenarios. After plugging in the various cables, including a USB cable to the host PC, I then installed the Microsoft Office Live Meeting 2007 (LM 2007) beta software client, which was designed to handle the RoundTable's 360° panoramic cameras.
