Just in time for the holidays! The Smart Home Kit enables you to turn any household object into an internet-connected device.
The perfect gift for the DIYer on your holiday gift list.
Modify your voice by experimenting with the Microphone and the Synth Kit. Add echo and feedback with the delay and change the sound’s character with the filter.
Start by building the circuit: power + split + microphone + wire + filter + delay + wire + speaker. To the other side of the split, add an rgb led.
Test out the circuit. When you speak into the microphone and turn up the feedback, you should here your voice start to echo. Adjusting the time will make your voice sound low and deep or high and fast depending on which direction you turn the knob. Make sure to adjust the filter as well - it is a little tricky. Make sure the cutoff is in the middle range and peak is not too high.
The Synth Speaker was not as loud as we wanted it to be for this project so we plugged external speakers into the output jack. This helps to get a much louder and dynamic voice changing sound.
Make a base structure for your microphone. We used the top of a round metal box. We drilled holes in the base for the knobs on the Filter and Delay, a small hole for the Synth Speaker wire to pass through, as well as a hole to secure the neck of the loudspeaker.
Note: Be careful when working with littleBits and Metal. The modules should never touch metal, as this will cause them to short. If you do work with metal, make sure to encase the modules in such a way that they can’t touch the metal surface.
Secure the Filter, Delay, and Synth Speaker to the base of your loudspeaker using tape or glue dots. The knobs should be sticking out of the holes you just drilled. You can disconnect the wire on the speaker from the base of the Synth Speaker Module in order to have the speaker sit on top of the base. Feed the wire back down through the hole and make sure to reconnect it underneath.
We then closed up the bottom of the base structure with a circle we cut out of wood.
Fix the neck of your loudspeaker to the base structure. We fed a metal tube through the hole in the metal box top and secured it in a collar we made on the wooden circle. You could also use epoxy to hold it in place.
Attach a small box to the top of the neck. We used wire to fix a small textured metal box in place. We also line the box with black paper to give it the look of a microphone and to protect the Bits Modules from making contact with the metal.
Place the microphone at the front of the small box. If you would like to conceal the wire going up the neck of your loudspeaker, you can disconnect the JST connector on the wire at the base of your loudspeaker and feed the wire up through the metal tube. Once out through the other side, reconnect the JST connector.
Place the rgb led on top of the small box and use glue dots to hold it in place. Then make a housing for it. We cut the words “on air” out of black paper and backed it with a red film. Then we totally encased the rgb led. This makes it so “on air” glows red when we power up the circuit.
Place the power and battery in the small box.
Customize your loudspeaker. We laser cut a plate with the names of the knobs on the Filter and the Delay. We also used the 3d printer to print custom knobs.
What will you say “on air”?
