Why vertical has more counter that the horizontal? Isn't the vertical contains less line than the horizontal? Edit: I don't know if this is the right answer but my guess is that one pixel contains rgb so there. So computer need to scan 3 times to display the correct pixel per row. The row he wants to display is 800 pixel, but divided by 4 is 200, match the hsync, and then times 3 (because it needs to scan the same horizontal line 3 times to display the correct r, g and b value), which is 600, match the vsync. Just as a guess. Or I'm just dumb and it's because there's 600 horizontal lines

Just connecting the horizontal pixel counter bits to the R G B monitor inputs should draw some nice stripes.

[@yueibm]

Brilliant! Vertical stripes, driven by higher bits buffered and voltage divided... 8 different color variations? More colors filling in going from left to right.

[@KuraIthys]

Hadn't thought of that. I figured you could just tie one or more of the RGB lines high (with suitable level conversion - though I assume the sync lines are at the same voltage level anyway) I actually thought the easiest thing to do with a design like this would be to wire some suitable pots to the R G B inputs, so you could arbitrarily change the colour of the whole display. The only thing I'm uncertain about is whether you actually have to cut the signal when outside the active display period. If not, you can literally just tie the inputs to an arbitrary voltage level (within the safe range of what VGA expects), otherwise you'd have to sync it with the timing counters somehow.

Hi Ben! I'm a high school student, going into my senior year this September. I took a computer engineering class back in grade 10, and struggled to find the motivation to complete my work and I lacked an overall interest in the subject. I recently found your channel from LiveOverflow, and your videos have personally sparked an interest into the world of computer engineering again. You take interesting topics, and explain them in such a way that even your most novice viewers can enjoy and understand. Thank you so much for the amazing content, and please keep it up!

it is too easy just a couple of transistors to make an amp cirquit

[@gayusschwulius8490]

@@SimonBauer7 Making a soundcard is anything but easy. You don't just need an amp, you also need some memory buffer that can be written to and read from at the same time and a DAC that is capable of holding a steady clock rate when producing signals. The amp is only the last stage of a soundcard (and, strictly speaking, it isn't even needed to qualify as a sound card, as you can also just use an external amp, we only integrate amps in sound cards for convenience sake). It's easier than making a video card, but not easy by any means.

[@TheChrisey]

@@gayusschwulius8490 The components required would completely depend on the rest of the computer ofc. If you used a modern CPU you'd have access to DMA and wouldn't need a memory buffer. Building a low quality soundcard is actually easy, more so than making the video card in this clip, but on the other hand, this video card isn't difficult, it's just tedious when you manually forge timers like this. Using more modern hardware you could simply use a fast enough microcontroller or FPGA and do almost all of it entirely by code and 1 single chip with a power supply. For a soundcard you could use a micro or FPGA with either an internal or external DAC simply using a decent crystal oscillator and prescalers. The sound card wouldn't need nearly as high of a frequency either. You could run it at something like 44KHz and just output a sample every tick in both directions. The key would be to find a DAC that is at least 16 bits

Everything looks great if you do all the work beforehand. its the julia childs method!

[@edgeeffect]
