Making Old Telephones Great Again (MOTGA)

You have no idea how bad I want you right now.

[Mister Obvious]

LMFAO...

[user113]

I will name you George, and I will hug you and pet you and squeeze you.

[Mister Obvious]

Oooooo! Squeeze me!

BWAHAHAHAHAHA, GOOD ONE!!!!!!!!!!!!!!!!!!!

Dude I JUST THOUGHT OF THAT SONG like an hour ago when I was watching something else.

WTF!!!!!!!!!!????????

[Mister Obvious]

I made a music video for it once but it was blocked in all countries.

[user113]

I've been thinking about that song all day. LOL

And this one.

[Mister Obvious]

Debbie Harry was hot as fuck in that music video...

I want to do Debbie Harry in the worst possible way. But that ain't what this here post is about.

I've finished up the circuit boards. They're spread out on the coffee table. First time I've cleaned the coffee table in probably two years. Thank God for interesting projects, huh?

There's not enough light today to take decent pictures on account of it's overcast, but I'll get some up soon.

I need to order another USB hub to connect all of these circuits to the main computer, which will probably be a C.H.I.P., as I'm using my Raspberry Pi as a file server and development system, and don't want to dismantle that setup. Here's the C.H.I.P., in case you're wondering what it is:

That looks tedious and intricate bro. I respect your skillz.

[user113]

Thank you. That means a lot to me coming from the Supreme Webmistress of the known universe.

[Mister Obvious]

ROFLMAO OMG I love you.

[Mister Obvious]

You don't have to answer.

I can see it in your eyes.

It's still overcast, and this hole actively repels light. I put a 25W LED lamp directly on the subject, and this is the best photo I could get.

Top of photo, left to right: LED display for the digit receiver; line finder and digit receiver on one card; 8x8 crosspoint switch; 4 SLICs on one card; ringer; call progress tone generator.

Bottom: 60 watt powered USB hub, C.H.I.P. single-board computer.

I think we've discussed everything except the line finder and digit receiver.

The line find simply polls the switch hooks of the SLICs in an endless loop to determine which lines are off the hook.

The digit receiver counts the pulses from a rotary dial and translates them into the digits of a telephone number. The phones in this system will have 4-digit numbers. I obviously could've given them one-digit numbers in a system this small, but dialing the number is part of the fun, right?

Rotary dialing works by disconnecting the phone line very rapidly. For instance, if you dial a 5, the line is disconnected and reconnected 5 times. You could actually dial a number by jiggling the switch hook if your timing was precise enough. Most people's timing wasn't that precise, which is why they invented the rotary dial.
