This cool simple hack, allows you to pick a Master Lock padlock, using a beer can. The hack involves making the beer into a flat sheet of aluminum, then cutting out a simple pattern. Once the pattern is made it can be bent to work as a padlock shim. This is a very simple hack and it works very well, i have tried it. No more worrying about forgetting the combination to your padlocks anymore.

If you are in need of a bench top power supply for all your electronic projects, this stabilized unit from hobby-elec.org might be worth building. As a undergraduate in college I based my senior project on this example. I needed a good power supply to test many of my other projects. I figured that I might as well just make something that can be useful even after I graduated. I did my research and found this power supply circuit example. the project was a bench top power supply, 5v – 30v @ 4A max. It was based around a switching power regulator. The guide shows how to complete the whole project and even test it.
This is not a simple project for the first time electronic enthusiast, but it is something that could be very valuable when completed. This guide is a translation from the original Japanese site.

Great article by Seiichi Inoue of www.hobby-elec.org. The article goes thought the process of building a bender to bend acrylics sheets. Perfect if you need to create project boxes or even custom computer cases. This information on this website is well presented and challenging. The bender is basically an aluminum square tube with a electric filament going through the center. The circuity controls the whole process and protects the circuit in case of a failure. I have seen generic benders on the web, but this is by far the most professional.
