Why I would love to win a zing laser cutter...
Since I was little, I have been taking things apart; for years, I have been looking through and learning from Instructables. I love inventing, prototyping, designing. I love it so much I started a very small product design business with my wife from my home, where we design, cottage manufacture, and sell my own original products. As with most dreams lots of work is involved. Any help I can get that lets me focus more time on designing innovative products and less time on the day to day mechanics of putting those designs into action will allow me to reach my dreams.
A laser cutter would speed up my prototyping phase of product design. With more efficient prototyping, I can increase my output and troubleshoot faster. A laser cutter means more opportunity and faster innovation. I can certainly get my business going on my own, but it won't be as fast or as fun as if I won a zing laser cutter!
What I did to show my skills...
In this Instructable, I will show you how I created a great magnetic combination lock that be can be installed in an application, where you would like to leave no evidence of a keyhole or combination lock with the same security of both.
Inspiration came from a book my wife bought me on vacation from a thrift store: The Boy Mechanic: Volume 1 by Popular Mechanics Co. A very fascinating book detailing projects that popular mechanics published around the turn of the 20th century for boys to build. One project shows how to build a wooden combination lock. That intrigued me, so I built a simple version out of scrap wood. That got me thinking about locks. What I thought would be really great would be a magnetic version of the combination lock. So you could pull the key off, and no one would know it was even a combination lock. So after lots of tinkering, drafting, and failing I departed a long ways from the wooden combination lock design they had and came up with my original Magnetic Combination Lock. I am sure somebody may have done something similar somewhere, but I am unaware of it.
Before we get into the details, please check out the video down below so you can see the finished product and how it works. I would like to point out that the goal of my build was not to create an indestructible safe, but rather to prove my concept of a magnetic combination lock that was functional enough to keep honest people honest. However, the design can easily be implemented with much sturdier materials with little modification to make a safe that would keep dishonest people honest.
--Please read the safety disclaimer at the bottom before attempting to build.--
SAFETY DISCLAIMER: (Not many people like this part, but when you use big tools you take big risks when handled poorly)
If you attempt to reproduce this instructable, you will most likely be using sharp, pointy, dangerous, fast spinning, grown-up-person tools that can cause serious harm or death to yourself and others, especially if not trained properly on how to use them. You should have read all the safety warnings for your tools and understand how to use them. You should also use your tools as intended by the manufacturer with the the proper safety equipment.
Also, you may purchase powerful magnets that can cause serious injury to yourself or others if handled inappropriately (E.G. inadvertently or intentionally allowing them come together too quickly which can cause the magnets to violently explode and send little tiny sharp metal shrapnel bits into your eyes.) You should read all the safety warnings and understand proper magnet handling protocol to reduce the risk of injury to yourself or others. Please use appropriate safety equipment (e.g. protective eye ware, etc...)
I am not responsible legally or otherwise for any harm, injury, damage to property physically, financially, or any other unfortunate thing you may do. If you choose to build from this instructable. PROCEED AT YOUR OWN RISK!
