How to scavenge electronic parts quickly and safely

Hi again! If you are like me, sometimes you take electronic devices home just to tear them apart and scavenge some electronic components or some dc/stepper motors. It's always a great way to learn about electronics and to save some money. Sometimes you get to know some new IC... sometimes you get some really expensive IC... sometimes you get an IC that you couldn't even buy if you wanted just one or two... So, my advice for you if you like to make some circuits for fun is to start scavenging all the electronic devices that your friends and family throw away.

Until today I always desoldered the components with a desoldering iron and a desoldering pump but that's really slow, really tiring and sometimes it's also very annoying when you want to remove some component that just won't come out of the board or gets its legs ripped apart after 5 minutes of heating, pushing and pulling. Removing conectors or ICs with lots of pins is always very hard too. And the worst part.. it's not good for your health since it releases lots of dangerous fumes. But now I use a new technique! :D

zParts, an open source, cross-platform organizer for electronic components

Hi! This time I'm writing to talk about a great organizer for electronic components that I found, zParts. Some days ago I decided it was time to organize the lots of electronic components that I have in my home lab. I thought about developing an application were I could insert the parts references, the amount of each component I had, and also with some button to open the datasheet without having to browse the folder with lots and lots of datasheets. However, before developing the application I decided to search if no one had done that work before and I found zParts, by Jon Ziebell. I gave it a try, and that's exactly what I needed. It is written in Java, so it works in whatever operating system you have.

It's very simple to use and allows you to create categories of components, subcategories, and components with as many fields as you desire. You can also relate each component to an image and a datasheet. What else do you need? :D In my case I don't remember anything else I would need, but if you do, you can always program it yourself, since it is an open source project and its source is available in sourceforge. If you need to organize your components, give it a try! To run it just open a console, enter the folder where you extracted the zParts files and enter the following command

java -jar zParts.jar

If you have tested it, liked it and want to add a shortcut for zParts in Unity in Ubuntu 11.10 just do the following steps:

1. Create a file under /usr/share/applications named zparts.desktop and paste the following code into it 

   [Desktop Entry]
   Version=1.0
   Type=Application
   Terminal=false
   Icon[en_GB]=/usr/share/icons/hicolor/scalable/apps/gdu-category-multipath.svg
   Name[en_GB]=zParts
   Exec=/<path to folder where you have zparts>/zparts_start.sh
   Name=zParts
   Icon=/usr/share/icons/hicolor/scalable/apps/gdu-category-multipath.svg

   NOTE: Don't forget to put the correct path in the 'Exec' line. You can also change the Icon line with the path to the icon that you prefer.
2. Go to the folder where you have zParts and create a file named .zparts_start.sh and paste the following script into it 

   !/bin/bash
   cd <path to your zparts folder>
   java -jar zParts.jar

   NOTE: Don't forget to put the correct path in the second line.
3. Give the script permissions to be executed

   chmod +x .zparts_start.sh

   And that's it! Now when you open the Unity board and type zParts its shortcut will appear.

If you use M$ Window$ you can also try out Component Organizer, which is a similar free software developed by a portuguese guy (user msr @ the portuguese robotics forum Lusorobotica. You can check the entire thread about it here).
