Get Inspired
For her inventing badge Rose has been researching into female inventors by searching online.
She was interested in a famous actress named Hedy Lamarr, who as well as acting had a hobby of inventing things.
Her most famous invention was an extraordinary new communication system used with the intention of guiding torpedoes to their targets during the war. This invention used the idea of frequency hopping, which switched radio frequencies for both transmitter and receiver preventing them being intercepted. However this technology formed the basis of modern wireless communication we know and use today, WiFi and Bluetooth, which Rose uses to watch Netflix and play music in her bedroom.
While investigating about Hedy online, she discovered a fact that she may have been the inspiration for Snow White in the 1938 Disney cartoon.
For the next female inventor Rose took a real liking to was Nancy Johnson because, in 1843 she developed the first hand operated Ice cream maker, which is still used today. Ice cream was originally made using very intensive labor and it often took one individual hours to make. Johnson essentially provided another way to make ice cream faster and easier than by hand and without electricity.
As well as her Ice Cream invention which Rosie liked because she eats a lot, she liked the fact that she was also a social empowerer, teaching women of the era that they can make their own way for themselves, something which was very uncommon at the time.
Design
For her invention, Rose has designed a tamper alarm to alert her if anyone has been tampering with the secret drawer in her bedroom. The idea is that if the drawer is opened or there are any noises in her room while she is away it will sound an alarm and give an indication that the drawer has been tampered with.
Make
To make a prototype model of her design, Rose used a BBC Microbit because they are easy to program and have a built in accelerometer to measure movement and microphone to detect any noise. Rose used the online makecode website to program the microbit, with a bit of help from Daddy for the external electronics.
This is the code Rosie used for her project if anyone else would like to use it.. https://makecode.microbit.org/_iaFHv679rgaC
