Red Pitaya based low-cost SDR platform

In this project, a large-bandwidth low-cost SDR architecture is developed based on a Red Pitaya board. The components of this architecture are chosen so that the bottleneck in the transmit/receive chain will be the board.

Keyboard technology: A 3D printed piano action and self-tuning controller​

How could a 3D-printed piano action help achieve the goal of creating a keyboard instrument that can withstand extreme humidity and temperature while offering enhanced musical adaptability? The self-tuning experimental setup uses a Red Pitaya unit to collect data from the piano strings.

BCI with the Red Pitaya
STEMLab 125-10

In this work, an EEGNet-based architecture is implemented on the FPGA of the Xilinx Zynq 7010 system-on-chip (SoC), the core of the Red Pitaya STEMLab 125-10. To achieve this, two optimization strategies are explored: some data reduction techniques to control the size of the model, and the fixed-point representation of the network.

Stepper Motor Controller using PYNQ-Z2

Implementing a softcore stepper controller on FPGA and running a custom overlay on PYNQ to control the motor using Python programming. One of the benefits of this method would be to easily scale up the stepper controller design and implement multiple of them on digital logic.

Noise Generator Circuit

Noise. It's everywhere and is inevitable, but it comes essential sometimes specifically and is fun to play with randomness. I am using a 2 transistor noise generator circuit which in fact induces noise in one transistor with an open collector and the other one amplifies it to provide the noisy output. The output is random and peaks are over around 0 to 30kHz(in the spectrum waterfall chart).

DIY Crystal Tester Circuit

Xtal are found in most RF and processing circuitry as an external component to provide clock and time reference for synchronization of internal system operations. Easy to find, get and collect, but testing them isn't that straightforward which is precisely what the project is about.

Particle Accelerator Simulator

The Particle Accelerator Simulator is an application that uses a Red Pitaya STEMLab 250-12 to set the parameters on a Libera Spark, an Instrumentation Technologies' beam position monitor particle accelerator. Red Pitaya sets Spark's machine clock on output 1 and triggers on output 2. It also sends SCPI commands to Rigol or Rohde & Schwarz's signal generator to generate RF signals.
