Creation Factory: December 2014
http://creationfactory.blogspot.com/2014_12_01_archive.html
A blog devoted to the use of engineering and creativity for the construction of ideas worth spreading. Friday, December 26, 2014. Listening to Digital Radio Mondiale. The versatility of the Software Defined Radio doesn't seem to have boundaries. While exploring the HF bands, I tried to decode the occasionally received signal from Vatican Radio ( http:/ en.radiovaticana.va/. Which as of this writing was the only station I could identify as sometimes transmitting in DRM. Wednesday, December 3, 2014. Long d...

Creation Factory: Custom Camera for Image Stacking
http://creationfactory.blogspot.com/2015/03/custom-camera-for-image-stacking.html
A blog devoted to the use of engineering and creativity for the construction of ideas worth spreading. Saturday, March 28, 2015. Custom Camera for Image Stacking. Being an interesting candidate for astrophotography. My task was to adapt an aluminium enclosure to contain the camera sensor and the control keypad:. A special nut to attach the body to a tripod was also added. In my setup I have used a T-Mount to C-Mount adaptor in order to fit my Samyang F6.3 500 mm catadioptric lens into this camera:. The s...

A blog devoted to the use of engineering and creativity for the construction of ideas worth spreading. Sunday, March 29, 2015. Exploring light wavelengths beyond what our eyes can see constitutes an interesting domain, because in a scientific perspective it can reveal characteristics of the imaged objects, that our eyes and/or visible light based cameras cannot see. While not having specialized gear for UV photography I decided to give it a try with a UV power LED that I had laying around:. First steps w...

Creation Factory: June 2014
http://creationfactory.blogspot.com/2014_06_01_archive.html
A blog devoted to the use of engineering and creativity for the construction of ideas worth spreading. Saturday, June 14, 2014. Reflashing a quad ESC to BLHELI firmware in an attempt to solve pancake motor cogging issues. As this quadruple ESC is based on Silabs MCUs, using SimonK would be out of question as it is only developed for Atmel AVR MCU's (besides of course its bad reputation in respect to pancake motors). Doing this however would be no easy treat, as first of all I had no Silabs specific progr...

In this age of mass consumption and programmed obsolescence, it is not surprising that a few years after you shell out money for a printer, the availability of its consumables starts to decrease, followed by an increase of the associated price. Indeed this is quite a rich piece of kit: a control board, the electronic heart of the printer, where everyt...

A blog devoted to the use of engineering and creativity for the construction of ideas worth spreading. Monday, December 30, 2013. Gathering with fellow pilots and Multicopter improvements. Today I just look for a safe and calm place to fly. Unlike a fixed wing aircraft, the ground requirements for an helicopter are rather modest. After having found that my colleague at work Luis Sismeiro (check out in his blog the post about this encounter, including photos and filming of the quadcopters: http:/ sismeiro...

BEC's, which is short for Battery Eliminator Circuit is a fancy RC hobby term for a DC-DC converter that steps down the voltage to a given value used for example by servos and control electronics such as radio gear and flight controllers. The result of this circuit was a very steady video signal which is totally unaffected by motor currents, even when pulling harder on the thro...

Creation Factory: Drone Recovery Parachute
http://creationfactory.blogspot.com/2015/04/drone-recovery-parachute.html
A blog devoted to the use of engineering and creativity for the construction of ideas worth spreading. Thursday, April 2, 2015. Failure is a concern that is always present in the operation of a drone. Given the continued increase in acquisition and use of these devices by the general public, safety is of paramount importance. Even the smaller devices of about 2 kg of total weight, in case of total failure at altitude, will fall like a brick and cause damage to whatever is below. The release mechanism is ...
