STAVEBNICE PANDA PLANT GUARDIAN

The cutest solder kit is here to save your houseplants!

This panda shaped gadget has gold plated contact points or probes that can measure the humidity of a plants soil. The kit is very easy to assemble and once finished, you can simply stick it into the soil of your favorite houseplant. The bright RGB LEDs that mimic the pandas eyes will light up every 30 seconds to show the status of the soil. The soil is either too wet, too dry or perfect. A word of advice, you do not want the panda to stare at you with fiery red eyes so keep your plant happy!

Because each plant has different needs, we added two thumbwheels to adjust the sensitivity. The right wheel adjusts the distance sensitivity and the left wheel enables you to adjust the moist sensitivity. There will be no dead plants on this pandas watch!

The kit is powered by two CR2032 batteries (not incl.) and theyll keep the panda alive for at least two whole months.

Features
gold plated contact points or probes that measure the moisture level
2 x thumbwheels to adjust the range and sensitivity
2 x RGB LEDs that indicate the moisture level every 30 seconds:
green: perfect soil
red: too dry
blue: too wet
cute panda PCB design
no electrolysis
not suited for outdoor use

Specifications
dimensions: 76.4 x 142.5 x 10 mm
power supply: 2 x CR2032 batteries (not included)
current consumption: 100 µA
probe length: 42 mm
weight: 32 g

STAVEBNICE ELECTRONIC CICADA

Ring in the summer with this beautiful electronic cicada soldering kit.

The cicada consists out of three PCBs to mimic the shape of this popular insect as best as possible. The body is mat black and the two wings are shiny yellow with golden tracks. To finish off the design, you can use the included components to add legs to the cicada. This way, it will have a real-life look!

So how does it work? Theres an on-board phototransistor that makes the buzzer sound when its dark while an orange LED flickers along. Youll have everybody fooled!

The bug is powered by a 9 V battery (not incl.) which will last about 30 hours when constantly in use.

Features
produces the typical cicada sound when dark
buzzer
on/off switch
