U.S. Police Already Using ‘Spot’ Robot From Boston Dynamics in the Real World
Massachusetts State Police (MSP) has been quietly testing ways to use the four-legged Boston Dynamics robot known as Spot, according to new documents obtained by the American Civil Liberties Union of Massachusetts.
And while Spot isn’t equipped with a weapon just yet, the documents provide a terrifying peek at our RoboCop future.
EZBoard Lite – The most user friendly Ender 3 mainboard upgrade
The EZboard Lite is another drop in replacement 32 bit mainboard for the Ender 3, Ender 5 and CR-10. Just like it’s competitor the SKR Mini E3, it is a significant upgrade for a stock printer. In this video, I take you through installation, the very user friendly online firmware configurator and test the board stock, with EZout filament runout, the EZabl Pro and BLtouch.
The Lie That Helped Build Nintendo
The story of a man, a lie, a video game handheld, and a business empire.
Gesture Controlled Raspberry Pi Rover
In this video I demonstrate a gesture controlled Raspberry Pi rover I created as a pet project. I recently purchased a Adeept Mars Rover PiCar-B and thought to extend it by adding gesture control functionality to it.
For gesture recognition, I am using a NodeMCU wired to a GY-521 (MPU-6050) breakout board. The NodeMCU constantly reads the 3-axis accelerator readings and transmits them to the Raspberry Pi rover over MQTT channel.
Though I have used Adeept Mars Rover but this application is not specific to it. You can use any rover/car and customize the driving logic accordingly.
Launchpad || DIY or Buy || Keyboard Matrix & MIDI Tutorial
In this episode of DIY or Buy I will be showing you how I created my own launchpad. That means I will show you how I combined a design idea with 3D Prints, WS2812 LEDs, tactile switches and an Arduino to create a proper MIDI instrument. While building I will also tell you a bit about a keyboard matrix and in the end determine what advantages the DIY Launchpad offers. Let’s get started!
Building a MIDI Controller Using Arduino
What do you do when you don’t have enough controls on your MIDI keyboard? You build a MIDI controller of course! Using an Arduino and some basic components this is an easier feat than you may imagine!

Tricks to get local NTP time for the ESP32 and the ESP8266 incl. Summer- and Daylight Saving time
In many projects (Arduino IDE), we need accurate local time. With our ESP chips, we have some libraries to get NTP time, as I showed in video #67. Most of these libraries do not adjust for daylight-saving or summertime. Today we will change that by using standard ESP functionality.
LEDs and Whats Wrong with the Maker Movement.
About a week ago, Hackaday hosted the Superconference. Dubbed the “greatest gathering of hardware hackers, builders, engineers and enthusiasts on the planet”, it featured talks on subjects ranging from 3D Printing to Security to Augmented Reality (AR). Media outlets jumping on the tech buzzword of the day would undoubtedly have had a field day if they had just copied off the list of talk titles.
While Kitty Yeung and Pat Dooley’s talk introducing Quantum Computing serve to remind us of how little of the potential of computing we have uncovered, it was Mike Harrison’s talk on LEDs that first caught my eye.
