Introduction: Raspberry Pi Alexa+Google Smart Speaker
In this project I will teach you how to make a budget smart speaker. The cost for this project should cost only around $30-$50 dollars depending on the materials and extra additional parts.
Raspberry pi zero
RGB light strip
1/4” thick by 3 1/2” wide by 24” long wood
Wood polish or stain depending on how you want it to look
3/4” thick by 24” Long by 3 1/2” wide wood
Step 1: Making the Measurements and Cutting
1. I use a spool of wire and traced around it to make a curve. The diameter of the circle is 3 1/2".
2. Next measure the distance between both sides. The distance between both sides is 6".
3. Afterwards draw the other curve for the other side
4. Cut this side off so you can trim it up.
5. Cut off the curved edges with a coping saw
6. Sand down the first one until the edges are smooth. Use p120 grit sandpaper. This piece will be your back.
7. Trace that wood 1 more time onto the 1/4" wood and sand the sides down. This piece will be your front .
8. next you want to take your 3/4" thick wood and use your 1/4" thick wood as a guide.
9. Next you want to draw another back piece but smaller and in the middle of the 3/4" thick wood.
10. use a coping saw to cut the center out.
11. Repeat steps
12. last you want to glue together the 2 middle pieces
13. (optional) cut a hole in the piece labeled back for a fan to go
14. Lastly I drilled a 3/16 inch hole in the back for USB port to go in
Step 2: Installing the Electronics
1.1st in the 3/16 hole that I drilled in the last step I inserted the USB wire into it.
2. next I cut a hole big enough for the USB port to go into on the back
3. Next I inserted the USB port In to the hole I drilled in the last step And then I hot glued it in
4. Next do you want to solder do USB wire to the USB port the image of a Bob will help you get the pin out right
5.next do you want to solder the positive and negative port of the fan to the positive and negative port to USB cable
6.now fan should turn on
7.(optional) Add on my blue indicator light on the back
8.now glue on the metal piece that are stacked together
9. Now screw on the front piece so you can sand everything
Step 3: Finishing the Body
1. Now you want to get a belt sander and yo want to sand down the sides
2. Now you want to take some wood putty and fill in all the cracks then sand it down
3.Now you want to take some polycrylic And put it on the speaker body
4. I put on five coats but you can put on as many as you want
Step 4: Installing the Electronics (continued)
1.next I install the speakers I took my speakers from a old set of speakers and I took the amplifier board out but you can buy your own amplifier board for it
2. Next you want to drill holes big enough to fit the speakers
3.now you want to glue in the speakers
4. Next I took a piece of plexiglass and cut the shape of the front piece out with the inner part also cut out
5.Then I glued the plexiglass on and took my RGB White strip and Wrapped it around the plexiglass and then hot glued it on
6. now you want to drill two holes for the volume up and volume down button’s
Step 5: Modding the Raspberry Pi
Step 6: Finished
