Planning, construction and commissioning of an LED illumination-based high-speed data transmission link
Hardware construction, C/C++, if necessary VHDL; To be assigned immediately; Supervisor: Peter Zipf

Everything you can do with an Arduino connected to a smartphone (iOS or Android) via Bluetooth LE/Bluetooth Smart. Especially of course sensor data, e.g. biodata ("Tricorder") or environmental data, capture and control servos or motors (LEDs are also ok). The smartphone is either 'only' the GUI or serves to collect the data and as 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 about what you can do with our 3D printer. So far there is a blueprint for the housing of a controlled soldering station (control on built-in Arduino board) and a support frame for a mini quadrocopter (about 15x15cm).

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

For a small quadrocopter a FPV system is to be assembled, gff. self-built and put into operation. The smallest device known to us has 6cm motor distance... but the video transmission is not very good (and also not digital!).

Planning and setup e.g. of a smartwatch or of a fitness tracker. Other gadgets are also allowed. The goal is to plan and build a working prototype of such a device that realizes all functions but may not yet be miniaturized to market readiness.

A device for making bat cries audible, portable, battery operated, with speaker and headphone jack. The ultrasonic recordings are to be transformed live into an audible frequency range, while maintaining a as "natural" sound as possible. Required Prior Knowledge/Interests: Electronic setups, programming signal processors and/or FPGAs, digital signal processing (DSP).

An array of microphones will be used to locate sound sources and draw them into a video image, also recorded, according to their loudness. Required Prior Knowledge/Interests: Electronic setups, programming signal processors and/or FPGAs, digital signal processing (DSP).
