FPGA Mister OZ case by Zemciko

Last crawled date: 3 years, 3 months ago

This is my complete case for mister FPGA computer. Design is inspired by my old Atari 800XE.
It uses only de-10 nano and small 32Mb module (not aditional mister board or mister usb hub), module for realtime clock is optional. Keys and LEDs are connected directly to board throu available 40pin connector. There is no on/off switch on case, so you need one directly on your 5v power supply. Printed parts are upper case part, lover case part. 2 small holders, one for micro sd extender and one for usb hub, 3 keys (reset, menu a user) and transparent block for two LEDs. You need to buy several other parts (most of them from ali or ebay):
(DE-10 nano .... 130$, 32MB ram module ... 25$)
40x40x10mm, 5v fan (i preffer something like sunon brand) .. 2-5$
rj45 extension cable with holes for screws - 0.3m RJ45 Male To Female Screw Panel Mount Ethernet LAN Network Extension Cable" ..... 1,7$
TF to micro SD card Flex Extension cable Extender Adapter ... 2,2$
USB hub (Micro USB To 4 Port OTG Hub - (all external pastic parts removed) .... 3,4$
2pc 5mm 2v LEDs (green + red) + 2x +-500ohm resistors ... 0,5$
cables/wires simple with connector to wire switches and leds to DE10 nano 40pin 2,54mm terminal pins. ... 0,5$
3pc cherry type keys (im using cheap brown ones) ... 1$
14 screws 4 smaller ones into de nano legs to secure board into lowec case. 4 bigger 3,5mmx20 "self taped" both with conical head. 4-6 small self taped like 2,5x15mm for securing usb/sd holders inside case. 2x M3x8 with conical head for securing rj45 extension cable.
Im using my own steel plate as fan holder (just cut from old power supply 0,5mm metal sheet) and small aluminium heatsing for fpga chip, something like 22x22x10mm to fit under metal plate and fan.
