| | | | | [AI summary] This is a detailed account of the design and implementation of a trailing edge dimmer circuit for a lamp. The author explored various components and concepts, including current sources, pulse generation, and the challenges of achieving a linear ramp for dimming. Despite the project's complexity, the author found the dimming performance to be less than ideal due to nonlinearity in the ramp and flicker in the output. The project concluded with a decision to pursue an alternative solution, such as a rotary switch, instead of a dimmer. | |

| | | | | [AI summary] The user is building a custom instrument that combines a current source/sink with measurement capabilities. They designed a front panel with cutouts for a display, buttons, and jacks, and used an aluminum PCB for the front panel with solder mask for silkscreen. They also designed a mounting flange for the front panel and a rear panel with cutouts for a fan and USB-C connector. The instrument uses an Arduino-based MCU for control and measurement, and includes a detailed mechanical and electrical design. The user is seeking feedback or comments on their project. | |
