You may well have seen the Micro Journal device before as it’s featured heavily over on Hackaday and been picked up by lots of sites. It’s a fabulous concept for those looking to dramatically reduce distraction whilst writing. Built around an ESP32 microcontroller and a display with an SD card, slot the Micro Journal adds mechanical keyswitches to round out this chic portable device. Often sold as a complete device, it’s great to see this Micro Journal DIY Kit version hit the Tindie shelves.
The kit supplies the majority of the bill of materials needed to create a revision 6 build of the Micro Journal. This includes the custom PCB for the mechanical keyboard, the enclosure parts, the ESP32, the display and SD card holder, the battery holder and all the fixings and fasteners. You’ll need to add an 18650 cell which are pretty common to source; you’ll also need to add the Cherry MX (or compatible) keyswitches and keycaps of your choice to round out the build.
The onboard SD card acts as local storage and, as Micro Journal is all text based, even a tiny 2GB card is going to be able to contain an individual’s lifetime of work. Yes, it will hold around 400 million words! For ease of use though you can set up Micro Journal to sync to your Google Drive (and, presumably, other similar services) meaning your work is near instantly available for further editing.
An 18650 cell will give around 30 hours of distraction free writing time and due to the nature of the ESP32 and firmware the device is instant on, meaning it’s ready whenever and wherever you are when inspiration strikes. You’ll need a few basic tools like screwdrivers and a glue gun to assemble the kit but the build process and the whole project is well documented. Just check out the GitHub and documentation links on the product page!
