We see startups encountering the same set of roadblocks over and over again. Here are the three biggest sore spots and our advice on how to get around them.

This tendency to want to innovate around every single aspect of a product stems from passion for the product and its mission. But while passion is indispensable, it needs to be tempered with rational thinking.

I’ve always wanted to make a product of my own — something small I could manage — and this seemed like a perfect opportunity. I decided to design a Raspberry Pi case that’s functional, affordable, quirky, and fun.

Having done all the research and scaled the considerable Kickstarter learning curve, I wanted to compile what I found to be the most useful resources.

The biggest pitfall for aspiring hardware entrepreneurs isn’t the funding part; it’s the hardware part and clearing the production hurdles.
