Just wanted to let you guys know I'm back working on the board again. I ended up having some work come up at the beginning of last week and haven't had any free time the past week. Now that things have calmed down I can finish the board up. :)

Thanks for the update, Tim. I still get a chuckle from your pretentiously polysyllabic profile prose. An amusingly astute archetype of alliteration it is.

Haha, thanks, glad someone gets it!

I came up with it about 10 years ago, back when blogs were at the peak of their popularity. A friend and I used to have a game where we'd try to find blogs with the most pretentiously verbose tag lines possible; run by people who think big words = smart. So anyway, I came up with that Polysyllabic Prose thing and used it as the heading on my website/blog for years, though I finally had to take it down awhile back, as I started using my site more and more for business.

Now I just use it on forums. At least people can see it here. :D

I've been occupied with other things the past couple of weeks too, but am still working away at the video version. I'm not going to bother with any more progress videos on YouTube; the next video will be of the completed machine.

My hand-drawn (scribbled) documentation was starting to get a mess and beginning to become a nightmare to prepare neatly by hand. Some of the schematics for various functional circuit blocks (the score counters for instance) take up multiple sheets of graph paper and stitching the pages together and trying to get the initial layout correct is too much of a PITA, so I've reverted to drafting all of the schematics for this project in CAD this time around. And with more than a weeks break I need to get orientated again. I'll hit the soldering iron again once the documentation for the currently completed circuitry is completed.

Attached is what I have completed so far. Full resolution versions currently here and being added:  http://www.glensstuff.com/videopong/

EDIT: Oops; several errors noticed in the "Paddle video generators" schematic. Fixed.

In what are those schematics drawn in? They have such a nice oldschool look to it. Like something you would find in a old service manual or magazene.

Protel 99SE, but I've made my own component libraries.

Just uploaded a bunch more schematics for preview & corrected some errors in the previous ones:

Looking very nice! Man, I wish the schematic capture part of DipTrace supported 45 degree wires. It looks so much nicer than the lopsided way I have to do it. :(

So I've spent the last two nights picking up where I left off with Scope Pong; I'll have a progress update soon. We're in the home stretch!

Yeah, LTspice doesn't support diagonal wires either, which annoys me. If you try to do X-ed wires it forces you to draw a Nazi swastika.

Yes it does.
To draw diagonal wires, hold down Ctrl while drawing the wire.

I believe you can hold down OPT (CTRL on the PC) to do diagonal wires in LTspice. :D

Just went and checked it, sure enough...there's your diagnol lines! That's just like the couple shortcuts I found in Solidworks the other day, totally changed my day-to-day work flow now. You're awesome Tim!

I've been using LTspice for years and still occasionally discover little secrets like that; it's especially bad on the Mac since there's no toolbar or real UI to speak of. Everything is shortcut keys or right click menus. It reminds me of a terrible Windows 3.1 program.

Though, once you get the hang of the shortcuts you can draft schematics pretty quickly. I wish I could do schematics as quickly in DipTrace!

Hi Timb,
How is the pcb layout progressing?

Yes, .......... Earth to timb, over.

I've been doing shack renovations, so have been a bit remiss on the video version. Getting back to it soon.

Yes, I'm getting back onto this soon! I've been going back and forth between two customer projects for the last month, but those jobs are done now and I've got a bit of free time to finish this up. :)

Sorry about the false start last time.

Hey guys, so I took time over the weekend to do a full review of the schematics and layout, in order to get back up to speed. It was well worth it, as I found several errors (one of them a showstopper). So now I'm proceeding with the final stages of layout (connecting all the blocks together) and hope to have progress by the end of the weekend.

Small update: I got a bunch of the remaining nets connected over the weekend and fixed all the errors I had found last weekend. Maybe July 4th will be Indepongdence Day? We'll see!

OK, that's good to hear  :)

I finally got back to the video version this weekend. After a late night this evening the colour video circuitry is all soldered up. I still have to reroute the interconnecting wires neatly, but it's currently fully operational. I opted for a green scoreboard/boundary, red paddles, a yellow ball and a white court net/divider.

Of the currently assembled panel, the colour video generation circuitry occupies the 150mm X 300mm board on the bottom left. The currently vacant 150mm X 150mm space directly to the right of this board will sport the regulated power supply electronics (+/-5V & +/-15V). Actually there are two independent composite video channels/outputs on the video board. One is the colour channel for colour monitors/televisions and the other is a monochrome output in which the luma component is only ever one of two levels - zero (black) or full amplitude white. I soldered up this additional monochrome channel as the colour video signal rendered in a greyscale when viewed on a monochrome TV doesn't look as good. Red, for example, has a rather low-level luma component (30% of peak white), and the paddles appear quite dark on a B&W display. For the monochrome channel the discrete video components for the paddles, ball, court net, etc, are simply logically ORed together. In the colour channel they are processed by a luma (Y) matrix to satisfy the PAL standard; Y = 0.3R+0.59G+0.11B.
     
The blank PCB currently tacked onto the top right of the assembled panel will sport the sound effects/synth circuitry and the remainder of the games control logic. That's the next part to get soldered.

I must admit it's all beginning to look a little complimicated now.......  :P

I'm not convinced the colour is really worthwhile - don't think it adds much to the overall experience and adds more complexity.

Actually the color generation circuitry does not look all that big. I would guess it mostly leverages signals from corresponding circuits that actually draw the objects, so it simply muxes in a different color tone depending on what is being drawn. PAL format is probably easier here.
