Currently the OCI standard is to use QUCS as a simulation environment, and KiCAD as a design environment. However wouldn't it be nice if everything could all be done with a single tool? Well that may be a possibility worth exploring. The CERN group has put some work into integrating SPICE into KiCAD. Just check out the video below!

Jay Carlson on his site has compiled an extremely comparative report of a wide range of 21 microcontrollers that are less than $1 USD. Selecting microcontrollers can be a daunting task and this acts as a great reference. Check out his work below!
