This is a video that explains the purpose and function of the signal interrupt module. This was the first module I developed and made as an effort to get familiar with KiCAD and other development instruments. It is a simple 8-channel 1:1 input to output signal interface unit that provides for signal interrupt and patch capabilities to external devices. The module also supports micro-patch capabilities from numbered input channels to differently designated channels via patch conductors and to 24-pin connector terminals.

Active Thermal Control for SBC Modules
This is a single-board computer (SBC) thermal management module loaded with variable controlled fans. Two manual settings for each fan at either high or low, provide for a steady level of cooling. Enable all fans at high or all at low for either maximum or minimum active cooling. Or assign each fan a high or low setting to get fully custom airflow as a fixed setting.
Conversely, continuously variable fan speed is possible from a sensor attached to each separate fan cooling channel. Each separate fan sensor is a positive temperature coefficient (PTC) thermistor rated at 60˚ Celsius. Attach any or all sensors to a thermally active device and the module increases or decreases assigned fans to an appropriately matched speed for optimum and efficient cooling.
