There are (at least) two new “Maker Spaces” in or near to Peckham…
In Peckham’s Bussey Building there is the new Hub Workshop which opened in 2015, I think. They have a laser cutter, 3D printer, CNC router and some other cool things. Very excited about this as it’s just a 10 minute walk from my house! Not sure they have much in the way of electronics test tools?
In Herne Hill there’s the new South London Makerspace. They also have a 3D printer, laser cutter and other tools and a bunch of electronics test tools. They opened in 2014.
There are also a number of other cool workshops near Peckham. Take a look at the Open Workshop Network map
