I’m working on an open source 3D printed vacuum cleaner robot: https://github.com/CodileAB https://www.instagram.com/wolley.xyz/ I’ve been working with it on and off for two years …

Yes, the container tabs are really nice if you want to make tracking harder for advertisers, LinkedIn etc.

I like the name, it means "Pictures" in Swedish. Is that intended?

Five years ago, I would have recommended AlphaMail, a service me and some others were building. However, it does no longer exists...

I totally agree! That is how I did it :-)

I had the N9 with MeeGo, best OS for phones I have ever used. Also very beautiful and easy to use.

I was just about to mention Digital Ocean. Very simple and easy, but MySQL is eating all my available memory...

I see that it could be true for many desktop and mobile phone applications but who should develop the operating systems, embedded applications and backends? It is a full time job j…

Well, typing is more of a motorical skill than programming. Almost everyone can learn to drive a car (manual gearbox) but the same could not be said for programming where problem s…

Do you mean the text? I was writing the text for me, as some kind of project log. Actually, I found a couple of errors in the design while writing which I wouldn't have found if I …

Thank you, it was exactly the look I was after :-) But the logo was supposed to be copper but it is "silver". I don't really know why... This was the effect I was looking for: http…

Sound like you have the right mindset ;-) The most boring part of the project was routing of all the bus lines in KiCad, but I knew that if a kept on working, the reward would be b…

Yes :-) Five PCBs cost me $250, but they can be made cheaper. Otherwise the price depends a lot on the components. Ceramic ones are very expensive and the whole computer would prob…

Sounds great :-) Only problem is the "not-so-great" keyboard :-/

Yes, the programming is the fun part so if you don't want to design a new computer from ground up, a kit or a complete computer is to recommend :-)

Wow, really cool. Do you have more documentation about the ISA bus implementation? :-)

Thank you :-) I think that the 68k will be more fun to write OS and other software for as it is 32-bit, has memory protection, and can run UNIX :-)

The easiest way is probably to buy an old computer from the eighties, but they can be very expensive :0 I don't know much about other homebrew computers, but mine (Calculon/80) cou…

Thank you, I will write and publish much more documentation as soon as possible :-) It is a four layer PCB, one for Vcc, one for ground and the other two for signals. I designed it…

I have not heard of BLS Pascal, but it is possible to run Turbo Pascal (version 3, I think) on CP/M, which I intend to do when I have the OS in place :-)

I actually own a Ti-82, but I have never programmed it :-)

I think maybe the regular black would be more beautiful than the matte black, it wasn't really what I expected. Adding fewer labels makes the task easier for me ;-)

It is a really fun project to do, so I think you should continue :-) I'm going to add more documentation on the website, like timing diagrams etc. that may be useful for other peop…

Yes, the composite solutions sounds more fun :-)
