# 2022-09-14 Keyboard This board holds 99 keys total, spread out across a qwerty layout (64 keys), a "function key" row (14 keys), and a combined numeric/navigation block (21 keys). Keyboard board, frontKeyboard board, back Sidebar: Oh yeah, this...
Now connect the USB keyboard. Pass the USB plug through the side of the frame. Then poke the plug through the hole in the middle. Now plug it into the USB hub. Make a loop in the cable and secure it with a cable tie. Place the loop over one of the hex...
Today I integrated the keyboard into the frame I have constructed. The first thing I did was to remove the front most dowel and cut a notch in the side panels to accommodate the keyboard.Now I'd like to brag that I was thinking ahead about how...
I wired the keyboard up to the Raspberry Pi 4 I will be using to run the Sol-20 emulator. I did enough testing to ensure that all of the keys are working as expected. At first some of the keys were not responding, but with Dave's help I discovered I...
The C64 mini fake keyboard is a joke. My keyboard is going to be functional. However it's easier said than done. I've looked around, in fact I spent innumerable hours browsing for a passable switch that would work fine in a mini keyboard. I don't intend...
The keyboard caused me a lot of trouble throughout this project. It ended up being re-done twice!Reading a PS/2 keyboard is fairly straightforward. Here is a snip from my Project Details page:The PS/2 protocol consists of 2 signals: CLK and...
The keyboard encoder is expecting 5V while the Raspberry Pi 4 operates at 3.3V. So to overcome this I purchase a Voltage-Level Shifter Module from Amazon. I also printed a "caddy" to hold the Pi 4 in place and added a small 30 mm x 30 mm x...
The keyboard is attached via SPI, clocked at 8MHz. Pi Pico is SPI slave. Unlike most emulators that connect a PS/2 or USB keyboard, the keyboard matrix is scanned by the actual software. So each OUT to the column select port is sent over to the...
Merry X-Mas y‘all!For the first time the front of the DSKY is closed. I‘ve finished Keyboard v1.0. Althrough I‘m not completely happy it‘s a step ;-) ...some sanding needed but I‘m pretty sure that it will not be the last version...First attempt...
I added support for both the PSX Lightspan Keyboard & Saturn Keyboard in BlueRetro. See pre-release v0.9.1. N64, DC & GC keyboard only send the raw scan code and let the console software determine the key press and release. Saturn and PSX keyboard...
We have a bunch of cheap phones we’ve been tearing apart, and wanted to post a some pics. Particularly, we’ve been looking to see how they make the buttons and keypads. Teardown Pics This one is a fake Nokia. Of all the cheap phones we’ve torn apart,...
This project has had a side effect I did not expect when I started this project - I actually started selling hardware on Tindie! While I really appreciate that other people around the world are genuinely interested in what I am doing, I realized that...
Long time ago it all started with me trying to find new keyboard. After couple of weeks browsing through every possible manufacturer I got an idea: "How hard it can be to build my own keyboard! It's just few buttons connected to microcontroller, I'll...
People asked me how to assemble the keyboard. I am planning to shoot a new assembly video as soon as I can, but until then...The self-adhesive pads supplied with ELLO are mean to go on the back side of the front board (called Panel). The assembly of...
I've pretty much completed the core library code for the VGA out and PS/2 Keyboard input handling on the Pi Pico, to be used as an A/V support chip on my JJ65C02 system and figured it was time for an update and even a video. The Pico outputs basic VGA...
