DipTrace – This is the electronics PCB design software I use for all of my designs.  I love DipTrace because its powerful, intuitive to use, and very affordable.  Most other circuit design programs are overly complex and very awkward to use.

Diptrace is a suite of programs including schematic capture, PCB layout, a component editor, and a package pattern editor. It’s very affordable compared to other PCB design packages which cost several thousand dollars, and it is available in several upgrade levels.

Each Diptrace level has a certain limit on the number of pins and layers allowed.  The most basic Starter edition costs only $75 but is limited to 300 pins and 2 levels.  Most PCB layouts need at least 4 layers which requires the Standard edition at $345.  The Full edition at $895 allows unlimited pins and unlimited layers.

Arduino and Raspberry Pi – The further you can take your product’s development on your own the more you’ll save once you need to hire an engineer to finish it.  The are several development kits available now that are designed to be used by tech-savvy people who aren’t necessarily engineers.  If you’ve done some computer programming and are open to learning something new that’s moderately complex then you may want to consider trying one out.  It will take you some time to learn, but if your budget is limited this can save you some engineering costs.

Arduino, Raspberry Pi, and BeagleBone are the three most popular development kits.  I use Arduino and Raspberry Pi for some projects as a proof of concept (I’ve never used a BeagleBone). Arduino is the easiest to learn and is a microcontroller based kit.  The Raspberry Pi and BeagleBone are more like a complete computer and are much more powerful. – A great website for learning basic electronics. Some really nice tutorials. – A fantastic online publisher for those wishing to either learn electronics design or to expand on their current knowledge.
