Might be relevant for your schools project? Liquid Crystal expansion for the AlarmClock project is 4 quid.

It could easily be simplified, though, as most of that code is for handling commands to set the clock over serial.

For capacitive sensing it can be quite important to keep the wiring paths separate. I think your duff banana could be because a cable is draped over it. Unlike conductive sensing, there's kind of a sensitive aura around the device as you influence its capacitance in various ways.

Cheers Cefn, never knew that :)

Great work. There's something there for everyone! Thought I'd share a few ideas, inspired by watching your video, which might be relevant the next time you rework the build.

Wondering whether something based on a dual-170 (docked) breadboard like the Memory Game... http://shrimping.it/blog/memory-kit/ ...might work for this project layout. Could be potentially quite elegant by eliminating the majority of jumper cables, though the 170s don't have power rails, which can be a pain. I suspect you'd just get away with it for the number of ground pins needed in this circuit. I pick 170s up at £0.60 each when buying a bunch in one go, so the approach is competitive to cheaper breadboards, especially given the saving on jumpers. On the other hand, some people like plenty of space with their prototyping.

When workshopping with solderless breadboards I also use these useful switches, which use less space and simplify layouts as they only have two legs! http://www.taydaelectronics.com/tact-switch-6-6mm-5mm-through-hole-spst-no.html
On the 7th of September the Surrey & Hampshire Hackspace will be showing at the Brighton Mini Maker Faire . We'll have a few things on show and one of them is an Arduino Shrimp based kit. I've spent the last few weeks workin...

Thanks for the tip on the switches and the alternative breadboards. Definitely interested in sourcing the 2 wire switches. It's great to find out about other layouts 

For Brighton our goal is for people to go away with not just the specific activities in the kit but also something that is adaptable and reusable so the 840 would give them more room for reuse. We've also gone for the fully protected Shrimp so they can add more powerful components without it causing too much trouble.

Looking at the video the mess of wires is mainly due to using standard jumper wires rather than routing.  
It the wiring neater the layout doesn't look so crazy.

Search for "Shrimp Memory Game" and you'll find the kit which was developed from this experiment. There are full details of the layout, suppliers and the code to download, (it depends on a non-blocking rtttl supporting library which I produced for the project which is also linked). The layout can be trivially transferred to stripboard/veroboard if you wish.

A great location for views over the Lake District, although during the summer a very busy road makes the outdoor tables less pleasant (more of an indoors, winter venue). I judge a place by its coffee and service, and they failed on both counts with a very small and literally half-filled cup of cappucino for over £2.00. They blamed the machine, yet refused to even fill the cup by hitting the button again, unless I paid for two coffees! It would be easy and cheap to do better, Broadway. Couldn't bring myself to call on the manager, so this Morecambe resident just won't be going back.

It's an amazing location, and should be a well-catered pub with river view. DIsappointed on all fronts. Turns out the Golden Ball don't sell either Orange juice or Coffee! Only diluted juice or cordial and a spoon of Nescafe! Black sheep ale was cheap, though. Was a lovely sunny day so we stepped outside to the beer garden, where we had to listen to 15-20 jetski riders circling around just off the river launch point about 100 feet away. They have about 5 miles of river, but like to show off, so they can ruin everyone's day immediately next to the beer garden. Don't go to enjoy the river if it's nice weather or a weekend, unless you like watching badly silenced Jetskis right in your ear for hours at a time. Don't go at all if you like coffee or fruit juice.
