Dave finally puts an end to the idea of Solar Roadways. We have the test results of the world’s biggest solar roadways project, the 1km long 336kW Colas Wattway project in Tourouvre France. Stand in awe at how impractical and expensive it is!, and SPOILER, how it won’t usher in a new era of renewable ...

Dave explains and demonstrates how out of phase digital signals can effectively double your voltage. The magic of moving your reference point. And how you can verify this with a differential probe. A question bought up in the comments of the previous LCD driving video. The HVP70 High Voltage Differential Probe Coupon code “bargainprobe”
