The Kelvin Crazy Cricket Kit is easy to build, consisting of around 20 through-hole components. It runs celfrom a Lithium button cell and because it’s power efficient, you won’t have to change the cell too often. It’s a great project for beginners but experienced constructors will enjoy this one too. Talking about the temperature or cricket is always a good conversation starter although this may be a different kind of cricket. With Kelvin, the clever cricket, you can talk about both at once. Sure, you could check the temperature on your smart phone but that’s so. . . boring. Using an electronic cricket is a much more entertaining method and a bit of a conversation starter, too. Mind you, Kelvin is just like a real cricket in that he won’t make a single chirp in daylight. It needs to be dark before he finds his voice. Then you simply need to count the number of chirps Kelvin makes to obtain the temperature reading. We have included various chirping options to speed up this process. Includes CR2032 coin cell battery.
