thingiverse

2019-03-02 Update: - Added LCDBezel-TouchVersion.stl: Bezel which works with the HyperPixel 4 Touch version. - Added Support1_v2.stl: Adds additional clearance around the border of the HyperPixel4 PCB. This is a case used in a proof of concept build for the Teensy Thumb Keyboard PCB. More info at: https://hackaday.io/project/162281-teensy-thumb-keyboard https://github.com/AnthonyDiGirolamo/teensy-thumb-keyboard I wanted a small tactile keyboard with a comfortable layout that could be used in any handheld based project. BASIC game console, graphing calculator, PDA, Raspberry Pi PocketCHIP replacement, etc. The main use case is a PocketCHIP replacement device using a Raspberry Pi 3 B+. I'd like it to feel better than my PocketCHIP "Mechanical" Keyboard design. There are a couple things that I plan on fixing before recommending anyone print this: 1. Add a slide switch cutout to the back of the case. 2. Create an LCD bezel compatible - DONE! 2019-03-02 Additional Parts: **Teensy 3.2** OR **Teensy LC** - https://www.pjrc.com/store/teensy32.html - https://www.adafruit.com/product/2756 $19.80 - https://www.pjrc.com/teensy/teensyLC.html $11.65 **HyperPixel 4.0** - https://shop.pimoroni.com/products/hyperpixel-4?variant=12569485443155 - https://www.adafruit.com/product/3578 $49.95 **PowerBoost 1000 Charger - Rechargeable 5V Lipo USB Boost @ 1A - 1000C** - https://shop.pimoroni.com/products/powerboost-1000-charger-rechargeable-5v-lipo-usb-boost-1a-1000c - https://www.adafruit.com/product/2465 $19.95 **Lithium Ion Polymer Battery - 3.7v 2500mAh** - https://www.adafruit.com/product/328 $14.95 **Slide Switch** - https://shop.pimoroni.com/products/spdt-mini-power-switch - https://www.adafruit.com/product/805 $0.95 **Panasonic EVQ-PAC04M Tacticle Switches** - https://www.mouser.com/ProductDetail/667-EVQ-PAC04M - https://www.digikey.com/products/en?keywords=EVQ-PAC04M 60x $0.0177 (order extras) **1N4148 Zener Diodes** - https://www.amazon.com/gp/product/B06XB1R2NK 10x $0.02 **Raspberry Pi 3 - Model B+ - 1.4GHz Cortex-A53 with 1GB RAM** - https://www.adafruit.com/product/3775 - https://shop.pimoroni.com/products/raspberry-pi-3-b-plus $35 **SD Card** - https://www.amazon.com/Samsung-MicroSD-Adapter-MB-ME32GA-AM/dp/B06XWN9Q99 $6.99 **Steel Thread Rolling Screw for Plastic, Zinc Plated, Pan Head, Phillips Drive, #2-28 Thread Size, 5/16" Length (Pack of 100)** - https://www.amazon.com/gp/product/B00GDXU4WM/ **M2.5 Machine Screws 6mm to 8mm long and matching hex nuts** - https://www.amazon.com/Hilitchi-400pcs-Phillips-Washers-Assortment/dp/B06Y3TVKMR/
