Walking robots were once the purview of major corporations spending huge dollars on research programs. Now, they’re something you can experiment with at home. [Technovation] has been doing just that with his micro quadruped build. The build runs twelve servos – three per leg – to enable for a great range of movement for each limb.

We’ll admit we are suckers for clock projects, and the more unusual, the better. We liked the look of [Peter Balch’s] astronomical clock, especially since it was handcrafted and was a relatively simple mechanism. [Peter] admits that it looks like an astronomical clock, but it isn’t the same as a complex instrument from medieval times. Instead,

One of the most beautiful features which the ESP32 has over the ESP-12e is the fact that, asides the WiFi, it has two other communication modules onboard. The ESP32 comes with an onboard Classic Bluetooth and Bluetooth Low Energy modules. For today’s tutorial, we will explore how the Bluetooth Low Energy Module onboard the ESP-32 can be used in projects. INTRODUCTION TO BLUETOOTH LOW ENERGY

Our first thought was that having big fins coming out of your VR goggles might not look very cool. But then we realized if you are wearing VR goggles, that’s probably not your biggest concern. (Ba-doom, tss.) Seriously, though, high-intensity graphics can cause your phone or device to get pretty toasty up there pressed against
