Planning, construction and commissioning of an LED lighting-based high-speed data transmission link
Hardware construction, C/C++, possibly VHDL; Available immediately; Supervisor: Peter Zipf

Everything that can be done with an Arduino that is connected to a smartphone (iOS or Android) via Bluetooth LE/Bluetooth Smart. In particular, of course, recording sensor data, e.g. bio data ("tricorder") or environmental data, and controlling servos or motors (LEDs are also ok). The smartphone is either 'only' the GUI or serves to collect the data and as an internet uplink...

What ideas do you have?

... if possible, of course, with electronics on board, preferably self-built or with Arduino/Raspberry Pi.

Here we want to collect ideas on what can be done with our 3D printer. So far there is a construction plan for the housing of a controlled soldering station (control on a built-in Arduino board) and a support frame for a mini quadrocopter (approx. 15x15cm).

What ideas do you have? Do something with our printer!

For a quadrocopter that is as small as possible, an FPV system is to be assembled, built and put into operation. The smallest device we know of has a motor distance of 6cm... but the video transmission is not very good (and not digital either!).

Planning and setting up a smartwatch or fitness tracker, for example. Other gadgets are also permitted. The aim is to plan and build a functional prototype of such a device that implements all functions but is perhaps not yet miniaturized to market maturity.

A device for making bat calls audible, portable, battery-operated, with loudspeaker and headphone connection. The ultrasonic recordings are to be transformed live into an audible frequency range while maintaining as "natural" a sound image as possible. Previous knowledge/interests required: Electronic setups, programming of signal processors and/or FPGAs, digital signal processing (DSP).

An array of microphones is to be used to localize sound sources and draw them into a video image, which is also recorded, according to their volume. Required prior knowledge/interests: Electronic setups, programming of signal processors and/or FPGAs, digital signal processing (DSP).
