Classroom HackSpaceChallenge/Buzzers/Buzzer

Hardware

4 buttons in some orientation

2 Leds ?

Buzzer or should that be in the hub?

Serialisation of data? Or should that be in the hub port?

Design

• Layers 1,2,4 = MDF/Acrylic
• Layers 2 = Laser Rubber.

Seems laser rubber is commonly ~2-3 mm. The top most layer will have to be thinner, MDF/plywood probably not a good idea. Will probably use 2 mm acrylic instead.

Thoughts

• Need some kind of status light in hub to say when handsets are connected.

Connections

• USB (micro or standard?)

Choice (a) student handset has a wire dangling out, that is plugged into the hub; choice (b) the hub has a wire dangling out that is attached to the students handset.

Either choice should have accomodation for tidying up trailing wires when not in use. Maybe use the same kind of design as most headphone-tidy wraps.

Ciarán - I'll try and design the case, electronics will need to be done by someone who know's what they are doing.
