We first replaced the original RAM chip with a IDT 7132 SA100P dual-port RAM that sits on a breadboard:
The other port is accessed by an ATmega 1284 to the left of it. Its code responds to simple serial commands and can read and write to the RAM.
An ESP32 talks to the ATmega over UART and frequently asks it to dump 16 bytes at 0x00A0 to tell the game state and player number, and 0x0100 to get the four player scores. When it detects a new game, it offers the player a chance to scan their RFID member card and keeps track of their score:
After the game is complete, any players who have scanned in get their scores uploaded to our member portal where we can sort them by personal best:
We found there were sometimes read collisions and the ATmega would block the pinball machine from writing to RAM which would cause crashes or odd behavior. The latest version uses two RAM chips, one acting as a shadow copy -- similar to yours.
Eventually we'll make a PCB for it and open source everything. Currently only half the code (the ESP32) is on Github: https://github.com/Protospace/pinballwizard
I use it like this:
cat example.txt | push
pull > example.txt
I didn't write an app, however. I rely on the browser notification API which doesn't have the best support on mobile unfortunately. It works great on desktop.
My inspiration was the same though. I do most of my work over ssh, and wanted a local desktop notification when a slow command was finished running.
It's useful if you set up bash aliases like "push" and "pull" so you can quickly move snippets of text across servers.
You can see an example here: https://github.com/BraydonKains/is-even/blob/master/python.m...
I'll be around for questions!
I wrote this tool for accessing Standard Notes on the command line:
https://github.com/tannercollin/standardnotes-fs
I imagine it would integrate with bash_log quite well.
Back your data up first, and I'm guessing you could just `cd` into your notes folder then use bash_log straight from there. You could also set LOG_DIRECTORY in your .bashrc to be where ever you mount Standard Notes.
If you have a 1000 Ω path and a 10 Ω path (in parallel), current will go through both paths. However, much more current will go through the 10 Ω path.
The current through each path ends up being the voltage applied across the path, divided by its resistance.
