I uploaded an alternate version of this video without any background music during the narration: kzbin.info/www/bejne/g2e7mpqfnN9khdk

It would be interesting to have a video explaining the logic of the pixel generator and what discrete chips and IC it would have required. The convertion to GAL logic would also be interesting, but there are a lot of video on that subject.

Awesome progress, Dave. Very impressive!

Thanks, Troy! I've started working on the PCB. I think it's going to be pretty challenging to make everything fit. (BTW, I'd love to see a video about your Pi Pico TMS9918A replacement project.)

@davehohacks it's coming... I'm a big-time procrastinator. 🤣 The project itself is going great though. I finally have the single board version with the RP2040 onboard working.I have a few short, unedited, unlisted videos linked in the GitHub repo.

@@TroySchrapel I procrastinated on my display controller for 2 years, so I think you're making rapid progress. Looking forward to seeing it!

Fantastic work. Amazingly stable video. Another request for less music please!

Noted. I'm planning to post alternate versions of Episode 03 and 04 without the background music (I hadn't realized that so many people felt strongly about this.)

@@davehohacks I figured it was probably best worth saying. I don't tend to like commenting negative things on videos, because boy it can hurt on the other end. But your content is so good otherwise I thought it was worth pointing out. I'm really enjoying this project!

Great work! Congrats on the successful design! Good luck with the PCB design! Question: why jump to FPGA and not go through a 5v CPLD design phase using something like an Altera MAX7000 series device? A 10ns EPM7128 may be large enough and fast enough to incorporate most if not all your VGA hardware logic.

@davehohacks 3 ай бұрын

Thanks! Using a CPLD is an appealing idea. My main motivation for using an FPGA is the availability of an open-source toolchain for the Lattice ICE40 series. I think you're right that the current design wouldn't require a large device.

@@davehohacks the old Altera MAX7000 series is supported by older tools that are now free but not open-source, such as Quartus. however, they do offer a lot of design and simulation facilities that you may find useful.

idk if it's just me, but the background music makes it hard to listen.

Good point.

Not hard to listen to, but not needed at all.

Hey Dave, meant to ask last time, but please can you consider not including the "elevator music" in the background? 🙏 I realise I'm just one, but being _very_ hard of hearing (essentially deaf) and on the spectrum, I find it almost impossible to process what you're saying. I love your videos and have been subscribed for years (since covid, iirc), but I haven't been able to watch episodes 3 or 4 because of it … 😊🙏 (Edit: just read further comments and see I'm not alone. 👍)

That music is simply killing me thankfully it stops after 5 minutes

@davehohacks 3 ай бұрын

Maybe I'll post a combined video for episodes 3 and 4 without the background music.

@rogerramjet8395 3 ай бұрын

Hey@@davehohacks … no worries for this one. (When I get some time, I'll mute it and read the subtitles …) But, I and clearly a few others would appreciate leaving it out next time. 👍🙏

@@rogerramjet8395 I think I will release alternate Episode 03 and 04 videos without the background music. Also, if you look at the "Episode03/Materials" and "Episode04/Materials" directories in the Github repo, there are scripts with the narration.
