Is LIDAR easy to use for hobbyists? DIY Roomba? Obstacle Avoidance System for Robotics

by

In this video we will have a closer look at a commercial LIDAR sensor for hobbyists. We will find out how the sensor manages to measure the distance to objects placed all around it and how we can use this data with a computer and an Arduino. At the end I will then create a small robot which uses the LIDAR system to “crudely” navigate through a room. Let’s get started!

Small Form Factor Gaming/ Emulation Build – Low Profile GTX 1650 + RYZEN 5 3600

This is Part 1 in a 2 part series In this video I put together a very small form factor Gaming / Emulation PC using an awesome HTPC case I found on Amazon known as the Goodisory A02 and it supports a low profile Dedicated GPU so a picked up as MSI GTX 1650 low profile Graphics Card and paired it up with the Ryzen 5 3600 and the results are way better then I expected! This build does an amazing job at 1080P gaming and it handles emulators like CEMU and RPCS3!

144 7-segment displays make up this delightful digital clock

by

Using 7-segment displays to make a clock is nothing new, but what if you combined 144 of them together to create an epic LED timepiece? That’s exactly how this project was made, allowing it to show surprisingly smooth mega-numbers and a colon set at an angle.

The build itself is controlled by an Arduino Nano, along with an RTC module for timekeeping and 18 MAX7219 drivers to activate over a thousand (1,008) individual segments.
