31 Unusual Uses For Coconuts



When I was in college, I got a job as a student researcher in my Engineering department. My job was to research coconuts. My professor was trying to find ways to turn coconuts into value-added products. The goal was help promote economic development in countries like Papua New Guinea where coconuts are plentiful but are not fully utilized. We researched all aspects of coconuts and how they can be used. As a result, I gained a lot of random knowledge about coconuts. So I thought that I would share some of the more interesting things that I learned in a project on Instructables.

Add Light Up Effects to Backyard Games Like Cornhole



Backyard games like Cornhole are a lot of fun. But you can make them even better by adding lights and sounds. By hooking up some simple electronics, you can make the board light up and play a victory fanfare whenever someone scores. Here is how to make it.

Collapsible Cornhole Boards



I wanted to make a set of cornhole boards that I could take with me to picnics and cookouts. Unfortunately, my car is too small to easily transport a set of standard cornhole boards. So I designed a set of board that will fold in half. That made them a lot easier to transport and store. Here is how I made them.

Electronic Water Tag Game



Everyone loves water gun fights in the summer. But you can always make something better by adding electronics to it. So I designed a set of water sensors and buzzers that will beep when they are hit with the spray of a water gun. This lets you play a game similar to laser tag but with water.

And if you want wondering, no it won't shock you or electrocute you. The circuit is well sealed in its housing and the amount of electricity that we are working with is so small that it couldn't shock you anyway.

Resistance Controlled Alarm



There are all kinds of locks and alarms that you can make. You can make alarms that are controlled with keys, keypads, remote controls, scanners, or anything else that you can think of. Just for fun, I designed an alarm that is controlled by resistors.

This is a basic motion sensing alarm that detects when someone enters the area. When an intruder is detected, it activates a siren. But what makes this system unique is that it is activated and deactivated by touching a resistor to a pair of metal contacts on the housing. This makes for an interesting kind of security system.

Make Your Own Box Set




Box sets are a great way to organize and display your collections of books, movies and magazines. But you can only get the box if you purchase the whole set together (usually as a special collector's edition). But what if you want to have a box set of items that you purchased separately. Well, why not make your own custom box set.

In this project, I am going to show you a simple method for creating custom box sets of whatever kind of media you are collecting.

Adjustable Temperature Controller For Heating Elements



There are a lot of different products that use heating elements. Unfortunately, many of them are not adjustable. For instance, most soldering irons are either on or off. It would be much more useful if you were able to change the temperature of the iron. This would allow you to use the soldering iron for lower temperature applications.

So I designed a simple control circuit that will let you adjust the output of a heating element.
