This is just a brief discussion of some of the choices that were made in the design of this project.First and foremost, everything was designed to be fabricated and assembled by me, "in house" so to speak. That meant that any chips had to be hand-solderable,...
7/29/2013: As I stated; been working on the cabinet for the Mirror universe project. I bought a couple of "project" Bally Star Treks from a fellow pinball collector out of Shertz a few years ago. These have been setting in storage for a while... and...
The previous update looked at voltage ripple and transients. Another important area to investigate is the switching waveforms. This shows the switch node and gate voltages. ---------- more ---------- And a close up: The first thing to notice is that...
Mike Jouppi12:55 PM Mike Jouppi12:55 PMOk, here is the board stack up Sven F12:55 PMOK, thank you very much. Your links are already helping me! Do you know any surface mountabe heatsinks manufacturers, too? So far I used some BGA-heat sinks and mounted...
So basically for now I setup my flutter environment and IDE. I am using vscode on windows. The first 7 hours of this tutorial, will teach you everything you need to know. I did skip dart and some other stuff, but I recommend this guide.
So now the kid is three years old. Sorry for not updating this in so long.Everything works fine and I ended up scrapping the dual pwm, 16-bit setup because honestly the single pwm, 8-bit setup sounded better. 16-bit sounds much better on a high quality...
Today, the 3rd prototype seemed in place. No leaks, no drip. The plants looked well (or rather healthy enough).Everything in order. We ordered the material for the final structure (pipes and bends) and we started designing the Genuino flowchart. We checked...
I have everything on the schematic now that I think I will need for the TTL PCB. It only takes 8 pages and 36 TTL chips. Creating a PCB from the schematic shows me I have quite a lot of work ahead with routing the 16-bit memory bus and 8-bit...
I do want to have an upgrade to my aging X230 laptop ready in the next couple of years, so I don't anticipate this fizzling out, added that I refuse to give up the TrackPoint and classic keyboardI do anticipate the timeline changing depending on my available...
Here are some pictures of the assembling of 16 pads:Note the little bumps made for reading the cell letter in Braille:Making all these pads was a very time consuming task that took me almost five hours to finish. I had no time to make mistakes, luckily...
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...
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...
Title says it all - just placed the order for version two's PCBs and feeling cautiously hopeful. The hardware on this board is a major step up from the last:Two MAX 10 FPGAs (one as the CPU and the other as an I/O controller) vs. one Cyclone IV16K logic...
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...
