With some function modules, we can build certain funny objects. Here I will introduce you a wooden recording box which looks like an antique_radio. Assemble the 6 wooden plates and stick other function modules together by using a glue gun. The box can record your voice when pushing the “Record” button. After that, pressing Button module and you can hear the voice you recorded. If you don’t like this sound, you can record them again. The recorder modules are repeated. You can make a wish or record what you want to express. You can give it to your friend as a present with or without simple packaging. However, funny box or your wish voice, I think they like it very much. Now let’s take a look how to make this project!
With CAD design software, you can design a shell to packaging the other modules together. You must think about distribution of all parts. Where can I plan the recorder module and how to layout the speaker holes. Having a logo and texts are good. You could add whatever you can think of.
Please see the 2D schematic diagram of the wooden box below. It is applied to Laser cutting. It is very easy to transform 3D to 2D with CAD software. By setting the export paramater, CAD software can export 2D data of .dwg/.dxf format automatically.
This job takes only 5 minutes. Please pay more attention to the holes’ state when cutting them. The power of laser cutting must be enough to clip the needless wood.
High speed, sharp milling cutter is good for the process, because the wood is tough. There are burring over the slots after milling.
You might know how to connect the wooden plates when you see the regular shape. Using the glue gun to make them connect stronger. Then install the other modules according to your design. Finally push the back plate along the two side slots.Just speaking, recording and listening. The wooden recording box is belong to you.
