Since June 2022 we work on LVICE2 – Lunar VIcinity Complex Environmental Explorer – mission to visit near-Moon space and gather some interesting data there. MAGLAB is responsible for development and delivery of two magnetometers. The first one, fluxgate sensor based, will be used to study plasma and solar wind turbulences. The second, AMR based […]

ECC is a popular device that nicely demonstrates the laws of physics. We decided to build a small one for the pre-Christmas physics show here at the Faculty of Electrical Engineering, Czech Technical University in Prague Fyzikální čtvrtky | FEL ČVUT . Warning: The device is extremely dangerous in terms of electric shock hazard. Do […]

What happens when electronics, programming, physics and mathematics come together? LED-CUBE – the final project of Honza Hřebec from the subject “Laboratory of Industrial Electronics and Sensors” from the Cybernetics and Robotics study program. Six panels, each with 64 Neopixel LEDs, are connected to a Raspberry Pi Pico microcontroller along with a three-axis AMR magnetic […]

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 […]

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 […]

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 […]

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 […]

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) […]
