In this instructable I will show you how to make a really cheap but effective light box.
Its not the most glamorous of builds but it can be built from household objects and i have been using mine for quite some time with no complaints :)
Step 1: Tools and Materials
Pen or pencil
Box cutter or craft knife
A sheet of glass from a clip frame or plastic sheet
A box lid big enough to accommodate your glass plastic sheet with enough room for an overlap (or any part of the box where its a solid panel)
A positional lamp (I'm using a daylight bulb but any bulb will do)
Step 2: Getting Started
Place your sheet of glass on top of your box and carefully trace round the edges (marked here in red for ease of identification) minding that if your using glass it can be sharp around the edges
Measure roughly an inch or so inside of the red line and mark a smaller square (marked here in green for ease of identification)
Cut out the smaller square
Step 3: Taping It Down
Place the sheet of glass onto the lid so that there is an even cardboard border around its edges and tape it down with half the tape on the glass the other onto the cardboard. I added additional tape to take the tape over the edges of the box (not seen here but you will next page)
Step 4: How to Use It
Once your glass is taped down simply rest it on your lap with the lamp below it pointing up or as you can see here i have propped it between my lap and desk and voila! cheap light box!
For even better results use the light box in a darkened room
Point of note: if you are using glass please be careful when leaning on it. This is meant as a cheap alternative to light boxes which are generally built to be durable.
