I got some PCBs made a couple of years ago from JLCPCB and it wasn't that expensive, with shipping, 5 boards of small size (cheapest ones, not suitable for every project) was about…

I've been prototyping for some time now and never really focused on getting my projects into PCBs. But yeah I guess you're right I can't really argue with you, I should improve my …

A Mister uses a more powerful FPGA + ARM CPU board along with extra SDRAM (I believe) to simulate known retro systems. This was a personal project to make a custom video game conso…

I knew what you meant by "easy" and I agree. Well, I think it isn't that hard to get an analog video signal going. Having a TV that took an RGB analog signal, meant that I could co…

Like I've said in a few other comments (I've been trying to answer some of the comments, everyone has been really nice and really interested), one book that got me started was "Mak…

Thanks :) Actually they are still being manufactured to this day, that's one thing I didn't mention in the blog post is that you can get a brand new Zilog Z80 today, the 6502 (the …

First of all thanks :) And if you do find some time that project seems really cool, I never really got to work with the STM32 micros, but they are really powerful and cool. Answeri…

Yeah I did put more memory than the old school consoles had, absolutely, however the RAM in those days was only used for data mostly because they also had the cartridge ROM (or ROM…

It looks awesome, congrats :) I'm sorry the hardware and code were stolen. And of course it's always worth reviewing, I got inspiration out of projects just like that and besides m…

Thanks for the comment :) I am proud and honestly reading all these comments of people like you saying awesome stuff and also saying this inspires them makes me even prouder :)

Thank you :) I am considering doing a series of blog posts, I don't know how often I could write them or if I could keep them going, but I will try. I'm not big in social media and…

Thanks :) I'm gonna try and keep posting.

Thank you :) I would love to learn more and be able to work with faster circuits like you. Yes it's way easier to work with "slow" digital circuits I had very little issues using b…

Thank you so much :) I'm actually a bit overwhelmed with all the comments and I'm trying to answer at least a few of them. Just wanted to say that, even without knowing you, I thin…

Yes the journey was very important, absolutely. Also I had set myself a specific set of goals that obviously are not going to make sense to most people and I understand that. It co…

Thank you, if it's something you like, you should try a hardware project, for sure :) And yes I am Portuguese, born and raised and I do know what you mean, there are mistakes that …

Wozniak is a legend and this no where near the quality of his work. The way he designed the Apple II was just amazing. Thanks for the comment :)

(I'm actually secretly a horrible person :P) Thanks for the comment :)

Thanks :) And yeah you're right...my bad... (EDIT) It should be a bit better now, thanks for the warning

Thanks :) Yeah, I already have another ongoing project based on a cheap FPGA board with a Cyclone II (quite old but it does the job), the idea is to keep it cheaper and much less c…

Z80 rules! Thanks :)

I'm really not that special, don't sell yourself short. And thanks :)

I thought about it, I really did, however, I really felt I didn't need the extra RAM, especially for the kinds of programs and games I was aiming for. And in this case "a handful o…

Like I wrote in another comment. There's a great book called "Make: Electronics". And you can get started with an Arduino kit, it comes with a book and several components. After th…
