In this video, I take on a challenge: Can I build a $400 ZSA Voyager inspired mechanical Keyboard on a $100 budget?! Spoiler alert — absolutely, and it's awesome! I walk through each step of the build process, from designing the layout and PCB to creating a 3D printed case and writing the firmware. By the end, we'll have a functional (and beautiful) one of a kind DIY ergonomic mechanical keyboard that feels super premium without breaking the bank! If you’ve been thinking about getting into custom mechanical keyboards, or just want to see what’s possible when you combine DIY spirit with a tight budget and a dream, this video is for you. The upgraded version of this project, the Mantaray Pro Wireless, is now available! It's a split wireless board with the same great layout, and packed with features. You can pick one up at If you'd like to build your own Mantaray Keyboard and want to support the channel, consider picking one up on my store using the link below.
