London Makers, this looks like the event for electronics hobbyists, the first Arduino hacking workshop for advanced users in London (July 21st / 22nd – 10 am to 6 pm) –

Lead by Massimo ( also founder of tinker.it) and Matt Biddulph (CTO of web start-up Dopplr.com), they will assist a group of around 15 hackers in self-directed projects during these 2 days. We’ll be handing out tinkering gifts and also have the great pleasure of having Waldemeyer (waldemeyer.com) be a guest speaker and present some of his work in that field.
