The lineup for the Newcastle Maker Faire, which will take place in two venues - the Centre for Life and the Discovery Museum - on 12 and 13 March has been announced.
More than 100 projects will be on show at the event, which is part of Newcastle Science Fest' 2011 , with items on display including a two-wheeled skateboard, a mechanical fire-breathing dragon and singing Tesla coils.
Gadget-builders - or 'Makers' - from around the country will be showing off their creations and visitors can learn how to solder their own gadgets, how to knit a neuron and how build a pinhole camera, among other things.
Artist Cassandra Harrison will be enlisting the help of visitors to the Faire to help create a large artwork called 'We built this city', using a special textile printing system from Japan called Gocco.
Justin Quinnell will be showing off his pinhole camera project, including a solargraph image of the Clifton Suspension Bridge in Bristol, recorded on the inside of a tin can over a matter of months.
At last year's show Matt Denton, owner of MicroMagic Systems showed off his IC Hexapod machine, a six-legged robot that has been designed to track and follow human faces.
Maker Faire runs from 10am to 5pm on Saturday 12 March and from 11am to 5pm on Sunday 13 March. Tickets can be bought on the day from either of the venues. Tickets cost £5 for an adult, £3 for a child and a family ticket is £10 and are also available in advance through the Newcastle Science Fest 2011 website.
