Assembly guides

The Open Colorimeter is shipped fully-assembled and ready to use. However, we will be adding assembly guides to this page for users that want to learn how it is made, modify the unit, make their own from the open source design files or as a classroom teaching guide.

Installing the battery

The Open Colorimeter unit comes with a 3.7V 420 mAh lithium ion battery installed. These instructions are included as they could be useful for anyone that might need to change their battery or upgrade to a larger battery size.

Parts needed for attaching a battery to your Open Colorimeter: 3.7V 420 mAh lithium ion battery, 4 sets of screws and nuts, Open Colorimeter 3D printed parts & electronics

Step 1: The battery is connected to the back of the PyBadge. Insert the white battery cable connector into the black connector on the back of the PyBadge as shown here. It should fit snugly into position.

Step 2: If you have a two-sided foam pad, you can secure the battery onto the back of the PyBadge. This is optional but will help to keep the battery from moving around in the instrument.

Step 3: This next step is a little fiddly but basically you want to manage the excess PyBadge cable. We found the easiest way is to create a loop and push the looped extra cable length into the space underneath the cuvette holder, leaving the connector end free as shown in the image below.

Step 4: Once you have the excess cable managed, place the PyBadge into the enclosure as shown here.

Step 5: Place the cover over the PyBadge. You can see the connector end is still free. Place a screw into one of the corner holes and a nut in the recessed hole on the bottom. You will have to hold the nut in place with your finger and a screwdriver to tighten the screw. Repeat until all 4 corner screws are in place.

Step 6: Finally, plug in the connector to the sensor board

And that's it! You can switch on your Colorimeter and are ready to start using it.
