Made a new video of my small 3D printed self-balancing robot running a simple obstacle avoidance behaviour using two analog Sharp IR sensors.

Quadcopter FPV video – Autumn flight
Edited from a single flight with one of my 3D printed quadcopters with carbon fibre motor arms. Info about my 3D printed quadcopters here: 3D printed quadcopter page
Flying at my local RC flying club Gamen. The video is recorded with the Eken H9 action camera.
Mini balancing robot with TMC2100 on an inclined plane
Made a new video of my mini balancing robot. I am now using TMC2100 stepper motor drivers, which makes the robot very silent and also steadier. I have also returned the PID values and increased the loop speed slightly in the software. A new version of the code is available on the Mini balancing robot page.
Obstacle avoidance robot
This is my attempt at building a really good obstacle avoidance robot. The robot is built to drive around a normal indoor environment without getting stuck on stuff. The robot uses an Arduino Maga 2560 and several sonar sensors to detect obstacles.
This robot also has a Raspberry Pi and camera module, that will be used for computer vision experiments in the future.

Arduino based DIY clock
I made a simple DIY clock based on Arduino. It uses a RCT module with battery backup, and a serial 7-segment LED display. More information including code, schematic and STL file download are available here: Arduino clock page
Simple mini balancing robot
I have created a small and simple balancing robot. It uses a single Arduino, an MPU-6050 and stepper motors. All the design files, code and schematic are available for download. Read more here: Mini balancing robot page

Assembling a 3D printed quadcopter
I made a video showing the process of assembling one of my 3D printed quadcopter frames with carbon fiber tubes. Read more about this quadcopter frame here: Quadcopter page
3D printing a fidget spinner
This video shows the process of 3D printing and assembling a fidget spinner. I have designed the spinner using Autodesk Inventor. The spinner is slightly asymmetric, making it easy and comfortable to start it. I use a ceramic ball bearing in the centre and normal bearings as weights. I always use Cura to slice my parts before 3D printing. To print in different colors, I manually edit the generated G-code file using Notepad++. Cura automaticly puts a comment in the G-code file at the start of each new layer. I use the search function to find a specific layer and insert a couple commands to lower the printbed and pause the machine so I can change the filament.
The STL files for the spinner is available on Thingiverse here.
