An enclosure for the CHM

Now the CHM is completely functional, but it's a mess of circuits and flying wires, let's make a nice enclosure.

A nice enclosure for the CHM

Here's what you need:

• A plastic box big enough to fit all the components inside
• A perforated prototyping board
• Two banana jacks (male)
• Two panel mount banana jacks (female)
• 2.5mm panel mount power jack(female)

First of all cut a piece of perforated board the right size to fit inside the box, place the components and solder all in place. Follow these schematics:

Connect the mosfet module:

 Connect the HC-05 bluetooth module:

Drill three holes in the plastic box for the panel mount connectors, stuff the circuitry inside the box (hold things down with hot glue), solder the female banana plugs and the power jack, then close the box(To reduce the size a bit, I switched the Arduino Uno for an Arduino Nano, not a big deal since the pinout is the same):

Last steps are to screw the motor leads to the male banana connectors, power it with 12V / 2A power supply and test it out:

There you go! Now it's easier to store and ready to play whenever you need it.

CHM now on Github!

Good news! The CHM source code is now on Github under the opensource BSD 3-Clause License, feel free to take a look if you're into technical stuffs!
