Tinkering with Neopixel LED-strips

Details: Category: UAV; Created on Tuesday, 11 June 2013 19:30; Written by Stefan Gofferje

During my LED-googling, I also ran across the Neopixel light strips. Those are strips made of WS2812 LEDs - RGB LEDs with integrated 2811 controller. Thanks to Adafruit there also is a control library, which makes it reasonably easy to control those things with an Arduino.

Control high power LEDs (1W, 3W) from the APM 2.5 LED output

Details: Category: UAV; Created on Tuesday, 11 June 2013 19:10; Written by Stefan Gofferje

I was looking for a way to make the ARM and GPS LED signals more visible for quite a while. Ideally, I thought, I could drive high-power LEDs somehow from that outputs. A short question in the comments of my blog post with the LED poles at DIY-Drones didn't yield any results except the reflex-like pointing to the jDrones JDIO board.

Suomalaista poliisia ei tarvitse pelätä

Saksassa saa soittaa hätänumeroon, kun löytää kadulta setelin, Afganistanissa taas ei tunneta rajavartiolaitosta. Viranomaiset ja käytännöt ovat eri maissa erilaisia, eikä maahanmuuttaja välttämättä Suomeen tullessaan tiedä, että täällä ei tarvitse pelätä poliisia.

MF450 Quad - Loiter test, flyaway, RTL and crash

Details: Category: UAV; Created on Sunday, 19 May 2013 18:43; Written by Stefan Gofferje

Went out flying today again and - it happened again. This time I had a flyaway due to strong wind and quickly lost orientation and the copter was over 1,5km away. I switched to RTL and the copter started fighting the wind.

Replaced RCTimer EPP props with RCTimer CF props, made anti-vibration mount for APM. Still bad crash in the end.

Security warning: Microsoft uses confidential data from Skype chats

Security warning

Already on December 16th, 2012, I predicted that nothing good can come from Microsoft's taking over Skype. Now my prediction came true. German IT News Agency Heise Online has proven that Microsoft doesn't only record all Skype chats. They actively use the data and seem especially interested in confidential information like encrypted sites, cloud storage and access codes.
