Fully 3D printed mini QuadroCopter

After some successful tests of my QuadroCopter I decided to make a step forward. The goal is to make a smaller UAV which would be able to fly around a house. Carried by this vision I designed a CAD model of the mini QuadroCopter.

RepRap losing steps

Some time ago I have written about my RepRap clogging problem. When I have switched to PLA I had some problems with extruder jams. It was solved by switching to different extruder and adding a fan for active cooling.

Securing Raspberry Pi from unauthorized access

If your Raspberry Pi is connected to the outside world it is vulnerable. In one of previous post I have described how to make web server out of the Raspberry Pi. There you can find how to make it visible using DDNS.

There are few simple steps which you should follow to secure up your tiny server.

Simple Dual Thermometer

I have done a few project based on AVR microcontrollers. Recently, I have given myself a chance to try out Arduino. After my home thermometer broke down I decided to make a new one. Also it had a few drawback which required fixing. After some time I decided to use Arduino and design a shield for it which would enable this board to measure the temperature and display it. So here it is:
