The classic Magic 8 Ball is an amusing toy for speculating about life's many questions. But it lacks versatility. So I removed the standard 20 side fortune die and replaced it with a digital picture keychain. Now instead of 20 responses, you have can have 60. It also allows you to change them whenever you want.
A glove box is a piece of equipment that lets you perform work on a subject while keeping it in isolation. A glove box is most commonly used to protect operators working with hazardous materials, but it can also be used to protect sensitive materials from the outside atmosphere.
In this project, I am going to show you how to make a DIY glove box. Since different applications require different degrees of isolation, inthis project I am going to demonstrate a variety of design features and how to implement them. You can then choose which features you want to use in your glove box.

No feature in a home captures the imagination like a secret compartment or secret passage. But no secret compartment is complete without a secret way to open it.
In this project, I share several ways that you can use a simple hanging candlestick (or anything else) to access a hidden compartment. There are a lot of ways that you can do this. You can use a candlestick to open physical latches and activate electrical circuits. The only limitation is your imagination. So use this as an excuse to have some fun and build a secret compartment in your house.

The heat of summer is upon us. So to help beat the heat, today I am going to show you how you can make your own custom soda cooler. As an example I decided to make a cooler that perfectly fits a pack of soda. That way you can take the whole pack out of the fridge, put it directly into your cooler and go.
There are a lot of different styles of cooler. But they all have some common features. First off, there must have a layer of insulating material to keep the drinks cold. Then on both sides of the insulating material you need a layer of waterproof material to keep it sealed. Then you need a method of attaching all the layers together. Lastly, you need a way of opening and closing the cooler. There are a lot of ways to make a cooler. So go make your own.

I am a big fan of garage sales, flea markets, and thrift stores. They are great places to find used parts and materials for your next project. But one problem that I often run into is not being able to test battery powered electronics to see if they work. Because there are so many different combinations of batteries that are used in portable electronics, it isn't really practical to carry around batteries for testing. One device may need 6 AA's and another may require 4 D's. So I came up with this simple pocket-sized variable power supply. It can plug into either a 9V battery or a 12V battery pack. You can then adjust the output voltage to match the device that you want to test and attach the output wires to the end terminals on the device's battery connectors. This lets you power the device long enough to see if it works.
