Use The Build Upon Bricks To Add LEDs To Any LEGO Project


As creative as LEGO has been with regards to producing their different pieces, there have been notable omissions that third-party vendors have decided to take advantage of, whether it be LEGO-compatible carbon fiber bricks or gold-plated tiles. Here’s another one we really like: Build Upons.

Yeah, I don’t get the name either, but it’s a set of bricks that let you add lighted sections onto any LEGO creation. Whether you want to make a building that looks occupied (lighted windows), a car with actual headlights, or a robot with glowing eyes, these bricks let you do it when combined with a regular set of LEGO pieces.


Build Upon consists of three types of bricks: LED, Power, and Bridge. LED bricks are 1x1 bricks that house a small LED inside; Power is a 3 x 3 brick that supplies power to the bricks, which it draws via wires from a connected battery pack that houses three AAs; and Bridge is a conductive brick that transfers power from the Power brick to the LED brick. Using Bridges, you can connect up to 10 LED bricks to each Power brick, which can keep them lit for up to 120 hours on a fresh batch of AAs.


Granted, having to plug in the power brick to a separate battery pack doesn’t quite make for the most seamless design. If you put in some planning before starting a build, though, you could very well hide the battery pack somewhere in the design (e.g. hide it under the bricks or inside a structure), so those creative enough could still build some pretty nifty-looking projects even with wires in tow.

A Kickstarter campaign is currently running for Build Upon. Pledges to reserve a unit starts at $25.

    This is really cool, and definitely would come in handy for those of us that make LEGO-MOVIES. I think it adds a nice touch to making a ‘live’ set with your figurines or creations–and like that it’s not too bright. It looks like it’s made pretty well, and wouldn’t be difficult to conceal the wiring for. I don’t know how durable these look, but they’re not too expensive either–is this for an individual or a set? I guess my only concern would be the fire-hazard factor of this, and also it’s safety-rating or variable for usage by and with children. Also, if you can leave them out over time or overnight without it getting to hot or becoming a hazard? It’d be really neat to invent and use solar-powered one’s of this technology. Perhaps soon to come!

    these don’t look very well built! i don’t see them lasting long, but i guess its a cool idea. not really something i’d invest in for my tikes, and honestly i’d be more scared of them electrocuting themselves with it or trying to chew on it out of boredom or something idk

    I like this. Now I can add some spooky lighting to my halloween legos. It will be easy enough to hide the battery pack behind a miniature wall and maybe add some reflection to it for a better look. It doesnt look all that appealing as displayed in the photo, but these are a really nice addition to the kazillion lego kits I have.
