UAV-MAG again in Australia

UAV fluxgate magnetometer from MAGLAB was flying again in south hemisphere, this time exploring the salty Acraman crater in South Australia. Worked nicely, see the pictures provided by Marian Takac. The recorded magnetic data are being prepared for publication…

UAV-MAG at Alaska

Another set of UAV-MAG triaxial fluxgate magnetometers from MAGLAB is measuring magnetic fields around the globe, recently close to Anchorage, Alaska, USA. The drone unit sensor got a nice skirt to help with stabilization during the flight. It helps to keep orientation steady which improves overall data quality (less disturbances caused by non-compensated residual non-orthogonalities […]

New 3D “Merritt” coils in MAGLAB

Generation of various magnetic fields is basic activity needed for magnetic sensors development testing and calibration. Ideally one can take advantage of a system that can generate an arbitrary vector of magnetic field. In this case a triaxial coil system is needed. Often the coils are made as Helm-holtz coil system (two circular coils per […]

Magnetic Field Probe with MMC5983

Created within the Team project in the first year of Master’s study program Cybernetics and Robotics at FEE, CTU in Prague – Authors: Roman Zima, Matúš Kaintz, Vít Machanec and Vojtěch Nydrle, supervised by Vojtech Petrucha (2021). It proved to be a useful tool to roughly check the magnetic field in various places as well […]

Inertial Cube

Česká verze níže… This post documents a fun demonstration experiment made for Maker Faire Prague 2021. Somewhere in our big faculty cellar we found an unused spare part of a flywheel intended probably for Mig-21 fighter jet attitude indicator. It looked as a very precisely made piece of engineering, so it would very inappropriate to […]

Magnetic field display

Bachelor thesis project by Vaclav Zeleny under a supervision of David Novotny – the goal was to design and manufacture a magnetic field display usable as a fun tool for discovering magnetism but also for serious applications (e.g. easy work with permanent magnets). A matrix of Hall sensors (8 x 8 in a single module) […]

STM32F042 based oscilloscope – F042scope

Software defined instruments are very useful tools, specific hardware can be used in many ways depending on the software (firmware). At the Laboratory of Videometry students are developing various SDIs under the supervision of Associate professor Jan Fischer. The instruments proved to be very useful both for home education as well as an entry level […]
