Here is a complete list of all circuits designed and built by Open Source Instruments Inc. (OSI) since its foundation in 2004. Circuits designed and built by OSI employees while working for the Brandeis University High Energy Physics laboratory during the years 1995-2021 are listed on our BNDHEP Electronics page. We provide a list of almost all the electronic components used in all these assemblies in a single Data Sheet Library.
