This is really impressive! Would you mind running it on:

https://github.com/Protospace/spaceport

This is a member portal for my local makerspace. Having a knowledge base will help other makerspace members contribute to the code.


Amazing, we are currently doing something very similar at our makerspace on a 1987 Road Kings pinball machine.

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


Can this be used on any System 11 game? And can it be used to read the current state of the alphanumeric display?


Yes, it should. As long as you can figure out the correct memory addresses to look at, you can tell the ATmega to send you the data.


Awesome! I really like the idea of scanning an RFID card to identify players.


Modern pinball machines already do this (not RFID, it's an optical reader for a QR code), implemented by the major manufacturer Stern Pinball. They have internet connectivity to log scores and achievements and tournament challenges and leaderboards. It adds a pretty cool dimension to the pinball scene.


Road Kings?!? :\


Nice work, Philipp! I wrote something similar at: https://notica.us

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.


Nice. Indeed quite similar. Great minds think alike hehe.

All of your examples include a "!", which is a special character in bash. Sure that works without quoting?


to save you the trouble of finding out for your self: yes, it works (! is not that special)


I eventually have to figure out what ! does. In my she'll it always leads to errors about some events and whatnot. I shall Google and find out ;-)


Oh wow ! is quite powerful. Some of these bang commands are quite questionable, but hey... Like !12 runs the 12th command from the bash history. That's seems super dangerous to me.


Here's a good collection of tricks like that:

Oh man I just found your other project: https://github.com/tannercollin/t0txt

I last have a command line pastebin called pcopy, which I host on https://nopaste.net

Great minds, I'm telling ya, great minds.


Oh wow, and your pcopy / ppaste combo is a similar set up to my other project, https://reg.t0.vc

I use it like this:

  cat example.txt | push
  pull > example.txt
Maybe we are long-lost brothers!


I wrote Notica (https://notica.us) to do something similar. It uses web browser notifications so it works on the servers you are SSH'd into and also to your phone.


I wrote https://notica.us to do something similar. It needs a web browser open, but works over SSH and to your phone.


Great work! I wrote something similar at:

https://reg.t0.vc

It's useful if you set up bash aliases like "push" and "pull" so you can quickly move snippets of text across servers.


Beautiful! We'll begin work on this as soon as we finish planetzero's idea, the isBool API.


Excellent idea, this will be our first milestone after we raise our seed round!


I got tired of seeing programmers struggle to tell if a given number is even, so I built this solution.

You can see an example here: https://github.com/BraydonKains/is-even/blob/master/python.m...

I'll be around for questions!


They were being fired for not knowing it so your contribution to society is legit.


> If anyone has any suggestions in the context of what I’ve posted, I’m all ears.

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.
