I want to get this really old graphics chip working with my RC2014. I have a breakout board that I designed but I've also got emulation hooked up in MAME of a reference design (34010 GSP with an 8-bit RAMDAC and 256K of VRAM) that I implemented as an RC2014 card. I got a toolchain going in Dosbox (with help from Bitsavers, who found the C compiler and assembler/linker somewhere) and now I'm able to produce really fast rectangles. I'm doing my usual bit of reverse-engineering Quickdraw, since this chip was pretty much designed to implement Quickdraw primitives in hardware. https://twitter.com/LuigiThirty/status/1244184548730179584?s=20

Did you buy one of those sets of PLCC vertical breakouts for breadboards, yet? Do it! It makes things so much easier. I will warn you that you end up constantly disconnecting the breadboard wires directly in front of the PLCC when you take it in and out of the socket, though. I finally bit the bullet and dusted off my old Twitter account for all of my project stuff. If you want your daily dose of hardware  , well... there you go:https://twitter.com/DrHendersa/status/1243708242234159106

I can’t seem to find the magic words to find vertical breakouts, but I found a manufacturer of PLCC to DIP adapters (Aries P/N 68-653000-11-RC) that has a few units in stock. Where did you find the vertical ones?

https://twitter.com/LuigiThirty/status/1250355564678246401?s=20 About 10-15fps on a 50MHz 34010 at the moment. Graphics primitives are in 34010 ASM, the rendering engine is in C for now. Engine operates in terms of S15.16 fixed-point numbers.

So with me and (most of) my team on furlough, I wanted a way to keep us all together while also being, ya know, safe. I do a ~2h team event every month, and sometimes we do couch co-op/vs video games or board/card games. I've been scratching my head about doing all this remotely, because I don't want to choose a game that anybody would need to shell out any money for, and it needs to be something 10 people can play. Codenames is one of the team favorites. It's got a simple concept, is quick and easy to set up, and despite saying 2-8 players you can really play with any number of people (but at least 2). My first idea was to use this keycard generator and stream a webcam of the physical cards over YouTube or something. The keycard generator is great, but with my only webcam built into a laptop, I couldn't get a good angle of view on the cards for the stream. So I booted up Unity and spent a couple of hours yesterday building a Codenames board generator. It uses a dictionary file I found online to make a deck, shuffle, and put down the "cards" in the grid. Then, I can click on cards to change their colors when selected. Since the cards are double-faced, going to the next board will flip the cards, then deal out new cards, etc, until the deck is used up, then it reshuffles and starts over. With this, I can share my screen over Discord so everybody can see the board, and nobody needs to download anything for this to be just like playing all together in person. It was pretty fun putting this together. I should do more stuff like this.

A small directory/drive usage application that i've been working on for the last few days. The lockdown has been ... not kind for my sanity.

The lower ones are supposed to be lighting around seating, the upper ones are soffit / ceiling lights. edit: made the gates look less basic,

I made a little tool to help you memorize long passages of text -- by forcing you to concentrate harder to read them. You incrementally ramp up the difficulty at your own pace by highlighting and corrupting portions. I made it as a small plugin to Notepad++, which I take notes in a lot.  It also kind of reveals to you if you're overconfident about having finished learning a section, if you come back the next day and find that you can't mentally fill in all the gaps. You could also use it to encode text that only you can read, because you're the only one who got to see its incremental corruption. The GitHub explains how it works: https://github.com/encyclopedia-of-code/memorization

pretty cool, can you limit the output characters to just a-z so the corrupt version looks more just like regular language?

Charlatan Eschaton posted:pretty cool, can you limit the output characters to just a-z so the corrupt version looks more just like regular language? Sure! Sometimes my own notes have actual numbers mixed in, so I wanted that, but it's up to you. For (lowercase) letters only you'd just replace the expression "chr( random.randint( 0x20, 0x7E ) )" in the code with "chr( random.randint( 0x60, 0x7A ) )". Or, replace it with a slightly more complex code expression if you want uppercase letters too. Happy Thread fucked around with this message at 04:00 on May 3, 2020 |

i installed notepad++ to mess with it, its fun! the only other thing that i think might help with memorizing longer stuff is adding a command to ignore spaces and maybe punctuation so that words stay separated. That way you're losing the letters but can still see word length and paragraph structure.

As someone with zero coding education, anything with more than 10 lines of coding is a chore, but I wanted some home-made creative backgrounds and I got bored of indoor photography. I still want to add color, and embed the equations and parameters as meta data into the images, but it's not critical.

More updates on the BeagleBone Black-based SatellaView clone that I've been putting together!  - I have a preliminary hardware design done, and the prototype PCBs have been sent out for fabrication. Everything is designed using through-hole soldering and components, which I did so that I can easily attach logic analyzer probes during debugging and development. - I registered a domain (https://www.beaglesatella.org) and have been writing the content for it the past few nights. - I've been getting the PCB, CPLD, and firmware files all together for preliminary upload to a GitHub repo. - I finalized the BeagleBone Black kernel's device tree overlay for the pin multiplexing. - I've been spending a lot of time designing the remoteproc interface between the BeagleBone Black PRU firmware and a kernel driver. This is my first project using KiCad, and I've found that it is pretty decent. I always used Eagle in the past, but this design was too big for the freebie license. I think that all PCB design software has product-specific quirks, and KiCad is no exception, but it is what it is. This is also my first project that uses a snap-off panelized design, so I'm curious as to how that is going to turn out. At least having the PCB will allow me to focus on the software and not on maintaining this breadboarded monstrosity:  Yeesh.

I've been pecking away at a Doom level editor to feel my way back into Mac programming. Probably should have used Swift instead of Obj-C but oh well. It's fun playing around with the Doom specs and WAD files, feels like I'm 15 again. All the memory/pointer poo poo in C comes back pretty quick and you have to do a bunch of goofy poo poo to get palette-based DOS VGA graphics on an actual NSImage. Doom stores sprites in a goofy custom format so I was working through glitches like:

Then I can shift focus over to kernel driver development and some more PRU firmware development. I'm pretty excited that it didn't catch on fire.
