//// Vox Populi is an open source project based in DIY interaction designs to fight advertisement and corporate branding in our streets.////
Step 1: Connect the Components
_Voice synthesizer type Cebek ref. C9701 or similar. (Basically a 20seg voice rec+play)
_Speaker (as big as you want, consider 4 cm /1.6inch diameter minimum)
_Infrared sensor (I used CROW ref. SPR-100, but any alarm infrared sensor should work also tiny like cebek ref.7288)
_Batteries (depending of synthesizer and infrared)
_Polyurethane foam, sold in spray avaliable in any drugsore
_Half plastic bottle
_Silicone mould (optional)
Step 2: Change Speaker and Rec Button
Change also the rec button for a lamp switch to make an easier interaction.
The switch is going to work better if you stick it to a piece of wood or plastic as a lever.
At the end, secure the connections with the gluegun to make sure it's going to work.
Step 3: Change Play Button
Follow the connections of the original play button and exchange them for the infrared. Remember to use the Relay.
Step 4: Protect
Step 5: It's Foam Time
If everything it's ok, then find a silicone mould (any pastry-mould should work) or any other PP / PE packaging (foam is not going to stick to it). You can also work without mould, by putting trhe foam directly on the electronics.
*Foam is not only going to keep things together but to protect them from weather
Wait util the foam is completely dry (also inside) - usually takes from 6 to 12 hours (see foam spray instructions)
Step 6: Battery Location
Step 7: It's Done!
(stick them to the walls with some more foam)
*depending on the batteries should work for a week at least
