Have you ever seen a Weevil? It's a pretty under-appreciated beetle, so we thought it deserved a kit. Okay, so we just kind of like the name and think it makes a cute board.
The WeevilEye is a through-hole soldering kit designed for the beginner. It has a low parts count so even young kids can easily complete it. Once it's put together the red LED "eyes" light up brighter or darker according to how much light is getting to the photosensor.
This kit comes with all of the parts you need to build your own WeevilEye as well as an instructional kit card that will guide you through the assembly process. You will need a soldering iron and some solder, an inexpensive choice for the beginner is the 30W Soldering Iron listed below.
Note: The "built-up" picture is of an earlier version of this kit. The current version does not have sewable tabs on the sides and instead has an attached coin cell battery. We're working on updating this picture.
