Introduction
Build a Light Touch enclosure from a cotton bud packaging, tracing paper and a few other household items.
To begin this step you’ll need to have your Light Touch breadboard assembly already made (one or two of them depending on whether you are intending to pair them yourself, or pair remotely). You’ll also need to have ready the necessary tools and parts which can be sourced from a range of independent online retailers - click the parts links for more details including tailored options for certain countries.
-
-
Gather the parts and tools shown in the picture.
-
-
-
Apply two layers of tape to cover the whole container.
-
-
-
Choose a place roughly in the centre of where you would like the button to be and make a pencil mark.
-
Very carefully create a hole using a pointed tool such as a bradawl, sharp pencil or the point of a compass.
-
-
-
Mark a point towards the bottom of the container. In this example the hole is being created on the opposite side from the hole made for the button.
-
Create two small holes with your pointy tool.
-
Open the hole using scissors until it is large enough to pass smaller end of the micro USB lead through.
-
-
-
The breadboard will be mounted upright inside the container, so we need to bend the LED's as shown in the image so that they will face the lid.
-
-
-
Take a generous piece of Blu Tack and stick it to the bottom of the assembly, on the opposite end to the LED's.
-
Attach the micro USB lead to the ESP32 board and carefully lower the assembly into the container, using the Blu Tack to support it.
-
-
-
Take the white capacitive touch lead and place it through the hole made earlier.
-
Try to arrange the lead so that the pointy connector is resting against the outside of the container - in the next step we are going to place aluminium foil over the lead and it will puncture the foil if it is sticking out.
-
Use tape to secure the lead on the inside.
-
-
-
Take a piece of foil and cut out a square (or any other shape you like).
-
Use the glue stick around the outside of your shape, but not over the area that is going to touch the capacitive touch lead.
-
Stick the foil to the container, being sure not to get any glue between the foil and the capacitive touch lead.
-
-
-
Trace a circle on the tracing paper around the top of the lid and cut out using scissors.
-
Add a spot of glue the centre and place on the inside of the lid.
-
-
-
Carefully place the lid on the container and switch on.
-
You may wish to adjust the position of the LED's shining on the diffuser, which can be done by carefully bending them in the board (making sure not to twist them so that the pins touch).
-
-
-
The build is finished and ready to use.
-
Enjoy!
