I'm not sure what Design Spark Electrical is for but are there any plans for some sort of EDA programme like Multism, Orcad etc.I have recently been using Tina-TI a free cutdown version of Tina supplied by Texas Instruments as I need to simulate circuits for audio work.I think something like this would fit perfectly into the Design Spark suite of tools and there are few free alternatives to the big and expensive simulation programmes aside from Tina-TI as far as I am aware. I'm sure something like this would be very popular and open up more customers to RS components.
