I've been working towards building a [Null 2 ](https://www.null2.co.uk/) for a few weeks now! The Null 2 is a [Raspberry Pi Zero 2 W](https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/) powered device, which means most of the tools and software is open source! Null 2 uses [RetroPie](https://retropie.org.uk/) which is a custom built OS on-top of Debian for running different emulators! The Pi Zero 2 should be performant enough to run up to some Playstation 1 games. I've started by ordering the entire list of part of parts which include: Included in the Null 2 kit: - 1 x Null 2 PCB - 2 x SMD buttons - 3 x Right-angled buttons - 2 x Right-angled switches - 1 x Set of rubber membranes - 1 x TP4056 charger (the blue board) - 1 x 3R9 SMD resistor - 1 x 3.2” ili9341 screen - 1 x PAM8403 (the green board) - 1 x PCM5102A (the headphone board) with headers - 2 x Speakers - 4 x M3 20mm acrylic nuts and bolts Not included in the kit: - 1 x Raspberry Pi Zero W - 1 x [1000mAh battery (5x34x50mm)](https://www.aliexpress.com/item/3-7V-1000mAh-503450-Lithium-Polymer-LiPo-Rechargeable-Battery-li-ion-cells/32838577178.html?spm=2114.search0104.3.114.6cc4136ayNI30z&ws_ab_test=searchweb0_0,searchweb201602_3_10065_10068_10130_318_10547_319_10548_317_5728815_10696_450_10192_10190_10084_10083_10618_452_535_534_10307_533_5025915_10820_532_10301_10821_10303_204_10059_10884_323_10887_100031_320_321_322_10103_448_449,searchweb201603_55,ppcSwitch_0&algo_expid=b89df036-19e7-47fb-b03f-ca6537777682-17&algo_pvid=b89df036-19e7-47fb-b03f-ca6537777682&transAbTest=ae803_4) - 1 x Set of 3mm/0.118” clear acrylic parts - 1 x Set of 5mm/0.220” clear acrylic parts - 1 x Micro SD card Tools/materials needed: - Anything you need to solder - Double-sided tape - Kapton tape - 1mm thick foam tape (optional) - Masking tape - A multimeter - Flush cutters - Acrylic solvent (e.g. Weld-on 4) - A piece of single core wire - Sandpaper You'll also obviously need a Raspberry Pi Zero 2W which.. are very hard to find right now. If you want to pay a really high premium you can always checkout eBay. Another option is to stay up-to-date on stock by using www.rpilocator.com. In some future notes I'll write about the process of getting the OS installed, building the case, soldering the components and installing the ROMS!
