Products needed for this DIY project:

1.      ESP8266 board

2.      High torque servo

3.      Wood

4.      Aluminium sheet

5.      Silicone mixture

6.      Epoxy

7.      Wood glue

8.      Gloves

9.      Amazon Alexa


Let’s get started with our DIY project!


Step 1:

First, you need to make a mold of your finger with silicone. You can easily buy some silicone mixture from a nearby store. Read the instructions on the silicone packet and mix the various liquids accordingly in a small plastic cup big enough to fit your finger. Once the silicone is ready, simply put your finger into it in a bent fashion and wait for the silicone to dry around your finger. Don’t forget to wear gloves while you do this step!

Step 2:

Once dried, pull your finger out and pour some epoxy into the mold and wait for it to harden. Later in this project, we will be connecting your fake finger to a servo and for that, you need to trace your finger on a sheet of aluminum, cut it out using a band saw or any other tool available to you and stick it into the epoxy that you poured in the silicone mold. Once the epoxy has dried, cut the silicone mold around it to reveal your fake finger!

Step 3:

Let’s move on to the electronics of this DIY project. We will be using an ESP8266 board that is an inexpensive, Aurdino compatible board that has Wi-Fi built on it. You need to program this board to suit the function you want your gadget to perform. This board needs to be connected to a high torque servo that will in turn be connected to your fake finger to perform the task when the voice command is given.

Step 4:

Take a small piece of wood enough for the servo and Aurdino compatible board to fit on. Glue on both these devices and stick some more pieces of wood on the sides to support the gadgets. Then connect your fake finger to the servo blades by using some small screws and a drill.

Step 5:

To connect your newly made device to Alexa, you need to program it and ask Alexa to explore local devices. The name that you have given this gadget will show up after which you will need to add it to your list of smart home stuff. Then you can simply activate it using voice command to perform whatever function you need it to perform.

Your DIY Alexa activated gadget is now complete! We’ve used this to automate a fake finger which can be used to press any buttons you want. You can use this to automate any gadget you want and make it perform any function that you want, it’s completely up to you! What is so unique about DIY projects is that you can customize them in any way, shape, or form that you want so let your imagination run wild. Enjoy your latest creation!
