Alexa-controlled wheel of fortune

Build your own wheel of fortune that can be controlled via Alexa

Alexa-controlled

wheel of fortune

se an Alexa device to spin a wheel

of fortune! It not only tells you what

your future holds, but also gives you

a random number or answers a

yes/no question. All you have

to do is say, “Alexa, spin the

wheel” (or any voice prompt you want). See

the complete wheel in Figure 1.

Let’s get started. The first thing we’ll

need is the 3D-printed parts. You can

download the printable files from

hsmag.cc/issue12 (see Figure 2).

The circular frame glues onto

the back plate; try to make sure it’s

central and evenly positioned. Then

glue the pointer to the top centre of

the frame. Finally, glue the frame to

stand (see Figure 3).

Insert and secure the servo so the

shaft is in the centre of the back plate.

Secure the shaft to the back plate using

either glue or a couple of small screws.

My screws stuck out through the back

plate, so I filed them down.
