Over the past few months:
- the controller that came with our central heating system, which for some reason the builders had not installed and used a different one instead. The box was knackered, but the controller looked okay, so I put it on ebay rather than chuck it in a skip. £44.
*bunch of random girlguide badges/patches thrown out by daughter who went off the whole guiding thing quite quickly. £23 
*Obsolete battery/tape style dictaphone, used but still in box. £46. 
*Random bits of Star Wars Lego (minifigs generally £5- £10 each). 
Anyone else want to share some inspiration?
