Field Programmable Gate Arrays (FPGAs), are powerful programmable logic devices that are commonly used in high-performance / high-complexity low-volume electronic designs. FPGAs differ from many other programmable electronic devices, such as micro-controllers, as the software deployed to them doesn’t “execute”. This software actually configures the structure of the FPGA hardware, such that it can perform…
I’ve had some fun this weekend designing a cheap remote backup server for my parents based on Armbian running on a Rock Pi S (stay tuned). However for such a versatile little SBC, there is a surprising lack of free CAD models in the wild. So, since I needed to design a simple housing for…
It’s become apparent that a I need a configurable multipurpose embedded control system. This is something I have been theorizing the designs for since I was in university (See Butterfly Board). Now with me putting a more intense focus on developing out the NullTek open-ecosystem, I would like to design and build a controlling ‘hub’…
There are multiple situations where automated switching of low-voltage power supplies to equipment is required. Such as cycling power to UUTs in production test, or programatically enabling power to home automation systems to name a few.
