Finally, B1 and B2 are completed and they.... kinda work... Although I'm going to have to check quite a few things.Remember how B0 performed flawlessly, both when connected via the expansion port, and when replacing CIA#2? Well, that's no longer true....
Genesis V0.5 exhibits the following changes from Genesis V4The Tracks cable carrier is repositioned and now supported with teenuts and long M5 screws, just like on the GantryThe Z-axis motor mounting bracket has been made thicker and the holes for the...
When calculations are done 1 bit at a time, one should probably not expect blazing speed. To measure the clock cycles per operations, I simply baked a 8-digit BCD counter into the system and increment it at each cycle, and reset to 0 at each...
While whizzing through the keyboard stuff, there is some special handling of some keystrokes. This is by scan code, so it's difficult for me to puzzle out what they are. One exception, though, is for setting the 'send speed'. There...
Let's start with the result:You can see a Teensy 3.1 and a dipsy connected to it. The Teensy configures the Dipsy and then sends single bytes over the SPI to set LED brightness. Here's the teensy code:#include #include extern const uint8_t dipsy_bitmap[];...
So I've recently got a fully electrically and mechanically complete CAD model of Tetrinsic and was, once again, doing some research for Tetent, mainly because I don't like how this featureless flat face looks: It turns out that the eteeController...
The unusual geometry of plotbot means that one has to find a way to map the Cartesian coordinates of what shall be drawn to the coordinates of the steppers in a way that the tip of the triangle that is formed by the arms will follow the Cartesian coordinates...
The address thing of the past few logs is... cool-that-it's-possible. If you don't recall from a while-back, the idea was to use a *default* address-location to use as a jumping-point to all other address-locations. A bit simplified, I'd write to address...
Sunday, 20/08/2023, 15:02 There is no way I wil be able to finish this project log in a single day or even a single week, so I will just post this here, so if someone wonders "is this project still being actively worked on?" then, they will know...
As Michael mentioned, he somewhat nerd sniped me with the the idea of squeezing a Towers of Hanoi solver in not the Science Fair Microcomputer Trainer. As an avid fan of both the Gakken FX R-165 and the Science Fair Microcomputer Trainer, I could't let...
After I convinced myself that the emulator was probably OK, I turned back to the ROM. But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...
