HotSpot MMDVM Case

thingiverse

This project is specifically designed for amateur radio use, requiring a valid HAM Radio license and callsign. I created this case in OpenSCAD as part of my MMDVM hotspot project, drawing inspiration from a similar design on Thingiverse (https://www.thingiverse.com/thing:2997294), but I took a different approach by designing it entirely from scratch. I want to acknowledge the original designer's work. This case is tailored for the Raspberry Pi Zero W board and a specific hotspot board purchased on eBay, accompanied by a 0.96" OLED display also sourced from eBay. Components needed: 1 Case bottom 1 Case top 1 Case frame 4 Standoffs 1 Raspberry Pi Zero W 1 Hotspot board (https://www.ebay.com/itm/For-Raspberry-pi-2018-Latest-MMDVM-Hotspot-Pi-star-Support-P25-DMR-YSF-Antenna/233145671274?hash=item3648909e6a:g:WgcAAOSww4Jcc8Wh) 1 OLED display (https://www.ebay.com/itm/US-0-96-I2C-IIC-Serial-128X64-LED-OLED-LCD-Display-Module-for-Arduino-White/322520336866) 4 M3 25mm hex socket cap screws It is worth noting that the power pins on my display were incorrectly configured and needed to be swapped when connected to the hotspot board. Otherwise, it functions perfectly. 04/26/2020 - For the display, I removed the 4-pin header and soldered in 4 short wires, which I then used to connect it to the HAT in the correct order. Additionally, you will require a micro sd card with at least 2GB of storage and an image from https://www.pistar.uk/ to activate the hotspot functionality.
