Since I am autistic, I have trouble understanding when exactly someone is making fun of me or what tone they are using, especially trough text. For the sake of friendliness I shall assume that you said all of that in good spirit and were not condescending. I knew about Ben Eater for many years, I am extremely interested in microelectronics.. I am also interested in chemistry and creating your own transistors and stuff - silicon, etc. ... but that stuff FOR NOW is unimportant. Did not know about James Sharman, though. There was a dude whomst I forgot about; he created his own RISC-V CPU and hardware around it - motherborad, even add-in PCI-like daughterboards for stuff like VGA and keyboard support if I remember correctly. That computer was a intelligent multi-story, stacked tower - great design, keeps things separated, cool-looking and organized. And if I were to create something usable, I shall write a super ultra-simple guide on how to do it yourself - DIY - unlike best of best manual pages *cough* *cough*. So almost everyone could make such a thing at their own home, perhaps not the FPGA itself (which I plan on preferring), but everything around it? I am unsure of the complexity of working with FPGAs - software or hardware wise. I admit my lack of such, but not knowing has never before stopped me from learning, and it shall not stop you. Like said - we have a lot of existing CPU architectures and other designs, and we can extract the best of the best from everything, and combine everything into something just beautiful! Okay, I browsed the James Sharman's YT channel, and just by reading the video titles - I got extremely excited! The moment I read "Storage (SD Card Support)...", I remembered that there exist web-siteS that explain how you can add support to an >>FPGA<< from storage stuff (SD, HDD, SSD), to networking, etc., which is more valuable than fucking gold! Holy shit if I don't archive their web-sites and all media they have, that stuff cannot be allowed to stop existing!! Since I extremely-extremely love problem solving - creating and debugging hardware ought to be fun! I cannot wait to spent 5 hours figuring out how I missed 1 resistor or whatever :') Anyways - assuming you were serious and nice to me - fuck genius ass or rather geniuses fuck good ass? -- Anon Loli ######### This mortal strives for omnisciency.
