Spookytron 1.0 parts list

I've been asked what I built the Spookytron with so here's a parts list. Lots of it came from eBay because I'm lazy.

• A biscuit tin.
• Four old PC speakers.
• A simple DPDT switch for on/off.
• Three 10K potentiometers and some guitar knobs.
• An 8-way RJ45 module pulled out of an old network patch panel.
• An Arduino Uno clone.
• A four way opto-isolated relay module.
• An Adafruit Wave Shield kit for Arduino.
• An Arduino stackable prototyping shield.
• A 1W amplifier kit. I would not use this again as it's not really loud enough, but I needed to be able to pick this up over the counter on the day.
• Four PIR modules.
• Two 6xAA battery holders and PP3 clips.
• Some RJ45 sockets.
• Loads of CAT5 cable.
• Other generic jumper wire.
• A small SD card.

In total this cost me about £70 before you consider things I had kicking around or got for free like the CAT5 sockets or speakers.

So a fun project but not one that's overly good value. If I refresh it I'll use an Arduino Mega for the extra pins and memory. The Wave Shield eats memory leaving you even less than usual to play with.
