  1. Glad to hear it is full speed ahead. Luckily the project I'm working on has no supply shortages except PCB companies who will make a PCB from an image file. The Z80 CPU, latches, and generic memory chips and counters are pretty much the only things used. If there was a PCB company who'd come to the party, we could prototype the SVGA output from this wizardry. The X16 is as good for games, but when the coming zombie apocalypse disrupts supply chains, look out ! Real chips like the Z80 will be the only thing to power the 150 foot high Mobile suit Gundams required to repel the raging hordes, if my calculations prove correct.
  2. +1 ! we need more goofy lore. (off to print that on T-shirts)
  3. Tony Kuphaldt has written some brilliant Electronics textbooks. Lessons In Electric Circuits there are link there to other free projects too.
  4. If you can post sufficiently hi resolution photos of both sides I'll tell you how to connect up a power supply. Worst thing that can happen is you'll be barbecued in a massive electrical fire, so may as well give it a go. No, seriously, post up some pictures. What is the part number, it may have obvious ques to the type. For example, you'd pick a name like TR-1201 for a 12volt AC 1 amp transformer, so when customers refer to it, you are prompted to know what it is.

  6. BGA to DIP adapters are available, but expensive. ( geared towards programming, so they are for repetitive use )
  7. Decoding the datasheets (they don't make datasheets like they used to) it has a 132 Ball pins on the IC. The pitch of (spacing between) the pins is half a millimeter. Regular DIP chips that people love to solder are spaced 2.54 mm apart. Thing is, it's a square array, so the next row is half a millimeter away. There are solutions, but they are fiddly enough to stop 98 % people doing anything with it. but not all bad news, there are big gaps in the ICE variant, so a designer could hack this at home, but it's beyond most hobbyists.
  8. From the number of logic elements, it's about comparable roughly to an 80's cpu afaik, but it runs at a whopping GHz. It is difficult to solder at home onto a board which is difficult to make at home. The price however, WOW that's cheap as chips ! With prices like that I would think to look at FPGAs for other projects... You need RAM. nothing that size can do decent video. yes yes huh and yes. I agree with this. I personally think that having an onboard bus for ram is a good option, because once you have the hardware available to access one Sram or Rom in DIP, that's the end of memory entirely, you no longer need to budget for larger memory so long as there is the Address and data bus exposed so that people can add their own. The project that shall not be named takes such an approach, because people will measure by the base model with un-expanded memory knowing full well that adding memory is a job a cat can do. (so long as a dog makes a tutorial video). PLUS there is the added benefit that you can try before you buy, or at least not get in as deeply as purchasing a fully expanded version. It's the investment barrier. You have to invest in learning all about FPGA and verilog and dip your toes in the YIKES! and then learn the actual programming to write your software, so is a scary, although perfectly do-able, option. Plus, once you have made the investment you're giddy with new knowledge and spaced out with imagination thinking of all the possibilities of what you can do with that new found knowledge and exploring beyond the X(men) projects. there are some clever solutions, but many people won't try them at home, they'd figure it too fiddly.
  9. no no, not that one, that was the one I got side-tracked to. The one I was searching for has little 3D printed keys, and the keys I don't think they have internal springs at all, they have tiny magnets in them, so when you press a key on the 3D printed keyboard, two magnets disconnect from each other, giving the tactile feel you are after, then when it descends there is another magnet that repels the moving part after you have lifted your finger off. That returns the key to the original position. No it's not off topic really, the X8/16 will of course need a look and image, the keyboard is part of it, and with low volume 3D printing takes to the fore.
  10. and thank you. I always thought toilet paper was a symptom of covid in 5 eyes countries. The rest of the world can't be bought so easily they know they won't run out of water. (for bidets and such). You learn something new everyday. I'm reminded of someone who complains that they hate their work. They go on about how "all day long I have to put up with people complaining they're sick" and how much they just hate that. I'm like "well isn't it a good thing you applied for a job as a receptionist at a medical center.

  11. More blender short films, SPRING, NextGen, Coffee run, Circle, Alike. Seems like someone is wanting names of short film projects that will get lost in a search engine.
  12. Free audiobook project for podcasts to listen to in the car can be found on libravox if you type the title into the browser carefully and correctly, otherwise Amazon jacks your browser and divertes you to a data and personal information credit card number collecting page with just two audiobooks as the cheese in the trap. Libravox looks like a forum like this website, the bait site looks like a give me all Ur stuffz site. Take care. On the actual site, there are nice audiobooks and here is a sample that I think is nice enough, but the quality varies quite a bit on there. Here is a link if you like that reader's voice and want more. This is the front door. This is the hijack site. Careful how you type. I've seen and read how many of the readers who volunteer and read the books on the real site are disappointed to find their work out on sale by amazon. Technically it is legal however, it disappoints many.
  13. Cosmos Laundromat is a very nice short movie. Also you should download Caminandes, which is totally cool and free, and Glass Half is awesome too. I look forward to seeing The Daily Dweebs and hero, I have seen agent 327 which is nice but short. These are nice example clips to pop into video folders that would otherwise be empty on distributions of operating systems. HAK5 is an ongoing weekly? show on the internet covering everything hacking and techno, it's been in business for decades, you can download, copy, distribute as you please for free.
  14. Free as in free to own and use as you like, not free as in you are the product ( facebook, youtube, etc ) Software : Linux operating system, everything you learn about it can always be useful even decades later because nobody can kill all of linux no matter how they try. In the sequel to the movie Tron, the son finds dads decade(s?) old linux machine which is strangely still powered up with dad trapped inside. He types linux commands into the old machine to get some info. I opened a terminal on my machine and copied each command from the screen, to my delight, they all worked, so over the decades, some things never change, and some things do change. Software Blender and GIMP : excellent programs to take the time to learn how to use. Free video to download, copy, distribute as you see fit, it's perfectly legal to do so : Short short movies from helpers who have learnt blender, Sintel, Elephants Dream, Buck Bunny, tears of steel not listed are examples of blender projects where you can download the actual files used in the short movies and play with the animations yourself. Have them act as you would like, or remake or expand on the movie as you tinker and learn on blender.Or you could take up smoking as a way to use up your free time, it's up to you. Some are other kinds of projects. Sintel, short story of a girl called Sintel who is searching for her dragon friend Scales. Three people searching a utopian society in northern Finland Valkaama; Route 66 -an American Dream is about Three Germans who try to explore the USA. Sita sings the blues is an 80 minute film based on the Indian Sanskrit epic The Ramayana. Massive movie created by a single person. Big Buck Bunny is about three critters that get their comeuppance. nice film, download it. Elephants Dream is a 10 minutes short movie analogues of the modern world, the generation gap, society... re_potemkin is a re-build of 1925 silent movie Battleship Potemkin which is public domain now. Produced by 100 Uni students. La chute dune plume is a French-speaking stop motion movie. A 20-minutes documentary about TINA festival in Australia. Filmed in 2002, This is one of the oldest open source documentaries that I could find. Boy who never slept about a writer Jathias Wager , the first Sci-Fi open source movie. “Stray Cinema is an open source film. It is an experiment that combines filmmaking with online information sharing.”
  15. I know where you're at there. Here is a good tip. All those little black power supplies that plug into the wall, keep a supply of white stickers in the house. When you do get the glasses and good light to see what is written on the power supply, Volts and Amps, scratch that information into the side of it in large writing and then add a sticker ( which may or may not fall off later ) with the same information in large writing. Not my intention I promise, however I am NO believer in the mind poison called self-esteem, it turns would be people into mindless trolls with no intention to improve themselves. I worry about the X projects. It is not good enough to think that a community IS the feature and will become a self-fulfilling selling point. also works if you buy something secondhand and clean it pricey though. I got a temperature controlled one recently, Oh luxury ! gas ones are good but don't last too long and some models are so have to choose carefully. I think I'd be in the market for trailer bumper stickers which read " WARNING - I WELDED IT MYSELF " . I know where you're at and I don't mind at all saying what I am not good at, I find pleasing ways to do it too. How about the question "If I wanted it and couldn't solder it, I'd buy it off someone who could if it was interesting. "
