Back in 2015 we told you about a very cool lighting system -- i-Brix -- that powers lights wirelessly, thus negating the need to route wires through your models.
The 2015 campaign was unsuccessful, but it's just been re-launched on KickStarter and this time it looks like it'll reach its more modest funding goal: it's already half-way to achieving it with 45 days to go.
The i-Brix system consists of a 10" 'Power Base Plate' that you position under your model, and small LED lights fitted in transparent 1x1 bricks. They are powered wirelessly from the plate, and can be positioned up to 8"/20cm above it. You can illuminate static models without the need for cables everywhere but also you could light up a moving fairground ride or similar which would be tricky using wired lights.
It's exciting stuff, so I encourage you to read more on Kickstarter and pledge your support.
