Nice easy electronic kit build. This unit simulates the sound made by the Cicada - a large insect found in warm countries, that produces a high continuous sound (apparently). In part 3, we hear the not-entirely-realistic output from the cicada simulator 🙂

Where I can get the kit???
I live in ohio, and we love hearing cicadas.. they come out in the summer.. the sound you played doesn't sound like the ones we have over here..
Whenever i hear them it reminds me of home
Complete garbage of a kit lol
Cicada's sound really different in China.
In the USA, Cicadas have a different accent.
It sounds NOTHING like a Cicada. It sounds like Lego men (and women) emergency vehicles.
Well, cicada sure have changed ^^
I'm buying one of these kits and running it off solar so my @#%hole neighbor can enjoy this year round >:)
Can't help but smile to a complete waste of time….LOL Perhaps some sort of entry alarm would be a good use. Nice vid series!!
They probably messed up the values of capacitors. Probably floating point at wrong place )
I want to hear cicadas ALL THE TIME! Although the sound isn't quite right here, I still love the sounds they make in the NC summers. For so long I had wondered where that sound went and then finally they came back! I have them on an 8 hour video for sleep.
Speaker polarity does not matter only in mono.
Alice has a batch of speakers with special low temp solder on the inner pads ready to ship just for you!
I haven't heard real cicadas (long a) since I was a kid when we had a huge outbreak of them in Wichita. Now I feel nostalgic for that sound. The bugs, not the fire alarm.
They're loud, but they sing with each other in a rhythm so it's kind of relaxing. Unless you step on them, then they get cross.
We also had hundreds of WW2 era air raid sirens to warn of tornados, which was the coolest sound in the whole world. The sirens I mean, not the tornados.
I think this device wants to be a Wichita simulator but it falls a bit short of both the cicadas and the sirens, I'm afraid.
To improve the circuit, perhaps they should dispense with that expensive speaker and instead drive a periodic 1KV pulse into a cicada.
