Unfortunately platform 21 has now closed, however the website is still worth a look if you're looking for inspiration for upcycling/ repairing objects.
Platform 21 also have an excellent repair manifesto, I particularly like point 2:
"Things should be designed so they can be repaired.
Product Designers: Make your products repairable. Share clear, understandable information about DIY repairs.
Consumers: Buy things you know can be repaired, or else find out why they don't exist. Be critical and inquisitive."
