Lighting up a runway into the garage

[Timo] didn’t want to look like every other lighted driveway but using solar path lights. Instead he decided to light it up as if it were a runway. It’s easy to look at the result as cute and move on to the next hack. But look again. If you were going to do this yourself how would you implement it considering a car will drive over it, and it’s outdoors?

The first issue of protecting this from traffic is actually not too tough in this case. [Timo's] driveway is made of pavers and is not a solid sheet of asphalt or concrete. He drilled out some of the intersections to make just enough room for each of the PCBs he etched to house the LEDs and host the driver. These boards are inserted horizontally into the sand between the pavers like a fin, with the surface mount LED positioned along the edge. Power and control wires run along each line of lights. They are serial controlled which cuts down on the number of conductors needed. [Timo] didn’t mention weather proofing but we’d suggest casting them in crystal clear resin just like this headphone amplifier.
