A New Plan

My rat detector doesn't work. I spoke to Simon recently and he gave me a great idea - what if the rat detector was a rat translator? I'm going to run with this idea and start researching about things that rats do, and what they are really (maybe) thinking. I have an idea for an old fashioned Victorian advert which I really want to make. I need to find a computer which can handle Photoshop. (Edit - done)

I probably ruined some of the components by soldering so slowly and overheating them.

Making a Poster

I decided to make a poster for my 201 project. It's meant to be in the style of a Victorian poster.

Here's how I did it.

I created a cream background. I applied clouds over the "paper" and added a border.

To give the "paper" an aged look, I increased the colour levels in the clouds and applied more clouds over a corner of the page and increased their colour levels.

Added text and an image!

About Bat / Rat Detectors

As scientists have used bat detectors to listen to rats, I thought I would try to build my own. A bat detector is a piece of equipment which detects ultrasonic noises and then converts these noises into something that we can hear. By using a detector you can find out if bats are nearby.

They have a limited range of around 25 to 30 meters. Many bat detectors are able to detect a range of ultrasonic frequencies. When using them with rats, they work best within a couple of feet, as bats are far louder and generally bigger than rats. Using a bat detector inside can also be problematic as electrical appliances create lots of ultrasonic background noise.
