  I know I don't really post here much anymore and I am still trying to figure out if I want to come back in any real capacity but I wanted to break my mostly-silence to announce that I brought up the memory interface board for #MiniDragon last night, integrated it this evening and successfully ran a small test program! The program is one that I wrote based on the instructions that I have brought up so far, assembled using the assembler I previously wrote and then burned to an EEPROM! The Mini...

  dear birds, why are you so full of noise?! sincerely, a dragon :dragnloaf:

  Hey y'all! I'm having another open house on Saturday May 23rd. These events usually kick off around 2:00pm and go until the last person taps out. I'm located in central Vermont off of interstate 89. It's about a 3 hour drive from Boston, just over an hour from Burlington, 45 minutes from West Lebanon and a little under 2 and a half hours from Montreal. My house has an arcade with almost 50 games mainly focused on older rhythm games from the BEMANI series but inclu...

  Okay, bringing up the shift instruction boards for the #MiniDragon if you want to come hang out! https://streaming.dragonminded.com/dragonminded/

• Post #1061300

  Today the shift instruction PCBs came in the male so I brought two of them up and verified them! These will handle the shift left, rotate left, rotate with carry left, shift right, rotate right and rotate with carry right instructions in the #MiniDragon CPU. The CPU only allows shifting left or right by 1 bit so these are pretty simple circuits. Once I get these on an acrylic board and integrated with the physical layout the ALU will be 100% complete and tested, so somewhat of a big milestone re...

  Finished laying out and wiring the very simple shift and compare acrylic. Part of the reason why it's so simple is that I don't actually have a design for or need for the comparison circuit at the moment. That's in a branch that I'm going to go back to after I finish getting the base #MiniDragon up and running properly. For now, the ALU cannot compare numbers so comparisons are provided by stdlib functions and called by the compiler. Once I design the CMP instruct...

  It's been roughly a month since my last post on #CritterChat so I figure it's time for another update post! Here's the changes since then: - Private group conversations are now supported including a room invite system! - Introduced privacy settings so users can control whether they're seachable or invitable on an instance. - Several usability tweaks, several UI layout tweaks, several small bug fixes (none big enough to warrant their own call-out) - Emoji upda...

  I'm still on the fence as to whether I should add SQLite as a supported database to #CritterChat so it's time for a poll! Feel free to boost if you think your followers care enough to answer. As a reminder, the repo for CritterChat is here: https://github.com/DragonMinded/critterchat If you have a more nuanced take or don't see an option here, feel free to reply. In terms of your desire and willingness to run a CritterChat instance:

  Six years ago to the day, this is what the #MiniDragon CPU looked like. One instruction (an older version of LOADI that only set the bottom 6 bits of the A register), two registers (A and B), two control signals (A load and reset), and only the bare minimum of support circuitry. No table to mount things to, and I hadn't switched to clear acrylic for the boards. No dedicated PSUs yet either, I was powering it off of a bench PSU. Missing was all of the 16 bit address registers, all other 8...

  Riding the coat tails of the latest Discord news to remind people that I'm working on a self-hosted chat service called CritterChat that prioritizes experience, ease of use and refusal to collect private information. I made the decision early on not to obsess over E2EE, we have plenty of services that support this and all of them suffer in every other dimension. I also made the decision not to sit atop one of the many larger JS frameworks that cause issues on lower-spec computers and spo...

  Spending a little bit of time finishing the wiring for this instruction decoder board on the #MiniDragon finally. I hope it works, because I'd like to be done with it and get it integrated into the layout.

  I guess the SAVE act is back up again and passed the house. This will disenfranchise millions of voters, including women who don't have passports but changed their name when married, active deployed troops who cannot come home to register to vote, and trans people who cannot get passports. Call your senators, urge them to vote no. It's easy. Just look up their phone number (either their state office or their office in DC), call in and state that you would like to offer an opinion...

  Restock time! #MiniDragon

• Post #587537

  These RTL circuits that I use in the #MiniDragon continue to prove themselves indestructible. Just reversed polarity on the new decoder board on accident and the only thing that happened was the voltage sagged in that corner of the CPU and the power wires got real hot. Found the mistake, reversed the wires and it's running like nothing even happened. This is about the dozenth time I've done this. Not once has it damaged anything beyond once melting through a DuPont header that I...

  Alright, finally got done diagramming the new #MiniDragon boards so onto the physical layout the last one goes! It's tested working as well! I also took the time to update the README with recent progress. Remember that the project is documented essentially down to the transistor at https://github.com/dragonMinded/minidragon

  I know this is last minute, but if anyone is going to be in central Vermont area on Saturday and wants to come over to an open house, hit me up (DMs open). I'm going to be turning on all of the arcade games (there's almost 50, focused heavily on Japanese rhythm games) and console games. Pizza hopefully available, but with nobody that delivers this is contingent on logistics day-of. #Bemani #Arcade

  It's been just over two weeks since my last post on CritterChat so I wanted to brag a little bit with a list of changes since then: - Emoji message reactions! - Country flags added to emoji search and reactions - Lots of UI design and QOL tweaks - Docker, thanks to @ThawnyRose - Better server CPU utilization - Several bug fixes to bugs found by members of the alpha test instance - Instance information is now displayed to new users and available at any time to logged-in users - B...

  Okay, a thing I've been wondering about with CritterChat is the implementation of private conversation invites. Right now anyone in a conversation can invite somebody else and anyone in a conversation can cancel an invite. That includes cancelling an invite you did not issue. The argument for is as follows: Private conversations are an equal footing in terms of ownership. There is no moderation and everyone equally can choose to change the group information, choose to leave, choose to i...
