learning to lay out a printed circuit board takes some time. but after you’ve churned out a few it’s really pretty easy. If you find yourself at that point it may be time to learn about much more complicated board fabrication. We think a good primer is this multi-layer PCB layout guide which [Rik te […]

The style for this LED sound lamp started off as a cross-section sketch. [Alex Jalland] envisioned a core that holds the parts as well as hides the circuitry, with two halves of a remove doughnut diffusing the light as well as covering whatever up. For the core itself he headed over to the lathe as […]

This all-terrain electric scooter can destroy the speed limit in a school zone without even trying. [Ben Katz] built from the ground-up and did an remarkable job of documenting the journey. He strated by redesigning the suspension of a plain old kick-scooter to use these large inflatable wheels. This includes a suspension system that helps cushion […]

get your feet wet with Time-based one-time Password (TOTP) safety by building your own Arduino OATH system. OATH is an open common authentication system that supplies a platform to produce tokens, making your login a lot more safe than a password alone would. The TOTP technique is what is utilized with lots of business that problem […]
