Designing for this project required many different approaches. Sometimes it was easy enough to take measurements, design the part in question and make it according to those dimensions. Other times it would be exceedingly difficult to measure all aspects...
I decided to release version 0.91 - the previous should be 0.90, then.No matter what, I added some more devices - 205 devices supported in total.I also changed somehow serial port handling, resulting in higher programming speed, especially under windows....
I did decide to use just 128 RGB LEDs in a 8*16 Matrix. This reduces the the circuit to drive them. I think I will use one 16Bit shift register (MBI5026 or compatible) for each color and multiplex over the lines. The current for each color can than bes...
At the Rogue One premiere Chopper experienced a failure of a shoulder bolt that nearly caused a catastrophic crash. So, the entire month of January was spent beefing up the shoulder linkage and redesigning his stance to use a better center wheel. Here...
So, I split my Sketchup file into a couple STLs, then imported them into XYZware.When I went to print the rails/corners/connectors in the previous log, my printer went BONKERS!!6 attempts and cleanings and still getting bird's nests. Tried different...
I think I've completed the (Tilelink) IFU design. I emphasize "think", because without the rest of the processor being built, it's not yet possible to know if I'm truly done or not. My next major step is to work on the IXU design. But, before...
Finished modeling the two axis motors today and came up with a first pass at the motor to slide holder interface. It's not pretty but it should get the job done, assuming it isn't too much friction for the tiny Y-axis motor to handle. I'll print these...
I played around with the code and a Game Boy Camera module, but it all was very weird. I was able to read the header once, and only after I unsucessfully read parts of RAM I was able to read the header again. I'm testing cartridges with RAM modules and...
Don't need much RAM - there are two slots for DDR2, could put everything into RAM but likely won't for now. So, will just put some 512MB sticks in there, test them one-by-one. Found one:Good! Tested it for 8 more hours, works nice. Found one more:okay...
Here's a realistic 3D printable case idea. Larger than I want for a final design, it will be sufficient for a prototype.It's 4.6" W X 6.2" H X 1.25" D. It would use 3D printed keys as well.There's still a lot of mechanical design that will have to be...
Some OpenSource/DIY software projects, containing legacy C code have been rewritten into C++. There is no any reasons to stay on C if C++ available on target platform. It has everything that C has and many "free" features, which cost 0 extra bytes and...
Unfortunately, Amazon shipped me the wrong breakout board from Adafruit. Not an uncommon occurrence these days. That said, I will likely spend some time to probe and record signals on each of the connectors coming into PB121. Just to make sure I understand...
What's up guys!It's midnight here and I just launched the Indiegogo campaign for my shield. Check it out here and be sure to share the link on social media because every view counts for me! Contributions are also greatly appreciated and will help me...
I've been building the GTXL one step at a time and checking as I go. So far, the power system, clock, program counter, IR/D registers, and control system is working. I made one mistake with the diodes. The artwork is reversed, so I installed...
