Kiri is a visual tool designed for reviewing schematics and layouts of KiCad projects that are version-controlled with Git.

Pythonic wrapper API for KiCAD's pcbnew v5/6/7 used for action plugins, GUI scripting, and batch processing

Digital controller for laser intensity stabilization based on the RedPitaya STEMlab 125-14 board

Use the HMC439 phase-frequency detector to phase-lock a laser beat note to an external reference frequency between 10MHz and 1.3GHz.

Low-noise transimpedance amplifier optimized for the photodiode SFH203.

Fast photodiode for PDH-laser-locking

Module for AOM-based modulation transfer spectroscopy (MTS) signal generation.

LM399 based 10 V/15 V sub-ppm stable reference

Alternative version of the MTS module (https://github.com/TU-Darmstadt-APQ/MTS_module) for 80 MHz and 200 MHz AOMs.

Front switch for the phase-frequency_detector

Produces a PDH error-signal using MiniCircuits SYPD-1+ phase detector and LT1568 4th order low-pass filter. To be used with a AD9959 DDS board.
