Hello, I’m interested in building my own [mechanical keyboard](https://www.apogeeweb.net/electron/what-you-need-to-know-about-the-hot-swap-pcb.html). My issue is that I want a tactile keyboard, but I also want it to be wireless because I’m tired of all the cords. I decided that making my own wireless keyboard would be the best option because the available wireless keyboards aren’t thick enough for me. Is there a way to make my own that is wireless? Are there any components on web pages dedicated to mechanical keyboards that could be used to implement this idea?

Hi Dan,

Welcome back 🙂

I haven’t seen much in the realm of DIY wireless keyboards - I’d say thats due to the smaller 2.4GHz receivers being a bit out of each for the hobbyist.

I came across [this Repo that uses BLE](https://github.com/T-vK/ESP32-BLE-Keyboard) - it would be a bit laggy though could work!  
This Reddit thread is also super interesting : [https://www.reddit.com/r/MechanicalKeyboards/comments/bby5y4/nrfmicro\_nrf52840based\_hardware\_usb\_support\_vs/](https://www.reddit.com/r/MechanicalKeyboards/comments/bby5y4/nrfmicro_nrf52840based_hardware_usb_support_vs/)

Also a notable mention is Zack Freedmans MiRage keyboard: [I Invented a Keyboard and Snapped it in Half (MiRage Mech Keyboard) - YouTube](https://www.youtube.com/watch?v=Fg0V5M0llaE)
