I'm a designer, here are my thoughts. It took me time to work out what your site is/does. I know that it's likely hardware/engineer-inclined people that would already be using the site, but if you want to appeal to the masses, you should put the 'About' paragraph in the footer up into the header so it's the first thing you really see. On the featured guides, I think you could include some engagement counters (number of views, number of likes etc) for social-proof. Also can be useful internally, to see the kinds of guides people are most interested in & you can start to target categories. To enhance the community aspect, you could feature how people have hacked products based on being able to pull them apart. I searched for 'iphone' & no guides came up. Fair enough if you don't actually have a guide, but for common gadgets, you could recommend 'similar guides' in the search results & bring up any phones for example (encourages users to stay on the site, even if they don't find exactly what they were looking for). I definitely think you need captions/instructions/tips etc on each image. The design is not great, but it is useable. Some of the above features are more pressing, but I would recommend doing a redesign soon, at least in the interest of the brand.
