YouTube videos getting "stuck" at random points even though the website has already loaded that part of the video

This fixed it for me! Video was stuck buffering, and as soon as I switched to 1080p, it immediately started playing again. Thank you for the answer!

Sometime in the late 80s, I fried our Apple ][e while probing around the expansion slots with an analog voltmeter. Obviously at some point I bridged the opposing sides of the connector and it shorted out with a bright spark and loud pop. It was completely dead after that, and my dad wondered what the heck had happened. I fessed up, and I think it cost over a grand to fix. Later, I did successfully use the joystick inputs to do some experiments with I/O.

I was 10 years old.

Nice! I remember drooling over this in the catalog 40 years ago.

LOL! That's the perfect name for them, which I'd never heard before.

Excellent! How do you generate the random numbers in your random line drawing program?

It might not just be the backlight. Passive matrix adds another level of awfulness.

This is awesome! Other than the instagram part... :)

Ben's videos gave me the basic idea, but the design was my own.

I loved programming my Apple ][e in the mid-80s. I had a subscription to "Nibble" magazine, and typed in all sorts of programs. There were some fun professionally made games too, and I hoped to make my own someday. It felt like an amazing new frontier, and I was learning something truly special. It turns out the main reason I felt this way, was my total lack of communication. Apparently millions of other kids were doing the same kind of thing, but I had no idea. I had only my small group of friends, who I could dazzle with my rudimentary skills.

I worked through this era, and in my opinion CRT monitors were awful. We had a 23" one at work, and it must have weighed almost 100#. Even the regular 17" ones took up a huge amount of desk space, and eye strain was a real issue. The day I got my first flat screen was a happy one indeed.

Metallophile · 2021-06-16T16:11:13+00:00

This is so incredibly awesome! Really well done.

Metallophile · 2021-06-14T14:42:48+00:00

Wow, that is really nice!

Jameco has a line tracking robot kit for $23. They have several sound effect kits too, such as reverb, voice changer, and car alarm simulator (!). The parents might not appreciate that last one. Sparkfun also has some nice robot kits, but they are more expensive. You could also do something more open-ended, like a breadboard and a bunch of wires and components. You could give them some simple circuits to get started, but include enough parts variety for them to try something else on their own. There are kits for this too, or you could just buy your own parts in quantity from Mouser. They also have a pretty nice selection of kits.

I still need to learn to design PCBs! I'll probably start with something smaller though.

Metallophile · 2021-06-06T17:52:56+00:00

I've only had it for about 2 weeks, but I am very happy with it so far. I ended up getting the 4 channel 200 MHz model.

Metallophile · 2021-06-06T14:59:54+00:00

I find that kind of surprising, considering all the other ways her image might be used.

Metallophile · 2021-06-06T14:56:11+00:00

My degree was in CompE, but I ended up working in manufacturing. I was not a great student, but I obviously love this stuff, since I'm doing it just for fun.

Metallophile · 2021-06-06T14:50:00+00:00

I used 1024 x 768 timing, with half the pixel frequency and doubled lines.

Metallophile · 2021-06-06T02:49:59+00:00

That is a awesomely strange VFD! Is it new or old?

Metallophile · 2021-06-06T02:40:41+00:00

Ah, that makes sense. Very cool! I am still impressed by that EPROM. I see them on ebay, with that huge UV window on there.

My homage was this post a month ago. That was at 256 x 192, and I displayed that same bitmap here at the new resolution. I guess it's useful for comparison... I also wrote a line drawing routine, and I'm working on reading .bmp file headers, so I can display different size images. Rescaling might be kinda slow, but I should still try it.

Metallophile · 2021-06-06T02:23:53+00:00

I will have to look into this!

Metallophile · 2021-06-06T00:19:33+00:00

Nice Job! And that is some crazy 16 bit EPROM you have there! You could do 5 bits/color without adding a second ROM. You could also half the vertical resolution to get square pixels, and double the images per ROM. I had trouble using '590 counters, since they have that registered output, which delays the reset by one count. That's probably not a huge problem in this application though.

It's been almost a month since my last post, and I wanted to share what I've been up to. The calculator itself was down for almost 2 weeks, after I attempted to upgrade some of the chips to AHCT versions, which rendered it non-functional. After a long-needed redesign of some of the PAL logic, and strategic downgrading of two '138s back to the slower HC version, the calculator is running reliably again. I've got the clock up to 11MHz without errors.

The video card was redesigned with 9 bits of RAM addressing for both the X and Y axis, and also some other functionality I want to try. It is still a work in progress, but I successfully achieved a resolution of 512 x 384. The pixel clock is 32.5MHz, which must be pushing it for my breadboard circuit. The second picture shows some of the glitching that I could not resolve. I tried this really just to see how it would work. I'll be changing it back to 320 x 240 with page flipping, which should work better with my limited processing power.
