So, further to the previous post earlier. I made a quick video showing the motor and code in action. Paper is on just to make it easier to see the motor moving.

So further to my previous video, where I measure out the required amount of Sodium Chloride, this video illustrates mixing the solution in a 100ml volumetric flask

Two parts to this video

1. Measuring Sodium Chloride
2. Making the actual solution

Depending on if you prefer Chemistry or Computer Science here are two takes on the Screaming Jelly baby.

Firstly Chemistry

Now lets look at the Raspberry Pi version. This is simply using a jelly baby as a switch to trigger a sound being played. So two wires inside the jelly baby connect together when the jelly baby is squeezed.

I prefer the Chemistry version, despite the fact it is probably far less interactive as in I don't think students are allowed to actually perform this demonstration.

Further to my post yesterday. I have been contributing to the Open Street Map project [1] with a few updates for the Torbay area, these are detailed on my OSM profile [2].

These are mostly :

• Adding website data for local schools
• Updating other data such as the School name if this has changed or different from the map listing
• Adding website data for other attractions
