VGA on an FPGA
I have been working with my FPGA boards to attempt to display a test pattern on a VGA monitor. For my experiments, I bought a small VGA monitor*. It has a VGA input, as well as a HDMI input, so…

Up until this weekend, I had never learned how to use a groovebox. My computerrecently died, so I decided that instead of spending money on a new computer,I’d spend it on an MPC One. I’m glad I did. I havenot…
I just spent four days disconnected from the Internet. It was strange. I also forgot and left my power brick for my laptop at home. So all I had was a Raspberry Pi 400 single board computer. It has a…
About a year ago, I built a SC131 Pocket Sized Computer designed and developed by Stephen C Cousins on Tindie. I soldered the kit and got it up and running, but left it alone for a long time. I bought…
I recently purchased a virtual reality headset. I remember dreaming about a future when this technology would be possible. When I was a kid (back in the 1980’s), I used to follow the scientific advancements on head and hand tracking….
I recently purchased an electronics kit for sending and receiving morse code. It has a port where you can plug in a telegraph key (I bought a red aluminum Iambic paddle), and a headphone jack. It comes as an unassembled…
Back in the day… When I was a kid (back in the 80’s), I used to come home from school and watch a great TV show about future technologies. I don’t remember the name of the show, but it had…
In a previous post, I covered the wiring diagrams, finite state machines, and LED segment encoding for the MAX7219 display module wired up to the Mojo FPGA. In this post, I will cover the Lucid HDL code used to implement…
I recently ordered a few LED display modules based on the MAX7219 chip. When they arrived, I immediately began putting together projects to use them. The first project was to wire one up to my Raspberry Pi and use C…
When I was in my early 20’s, I setup my Korg Poly-Six synthesizer so that the audio output fed into a Radio Shack (Realistic) Reverb Machine with the output of that going back into the synthesizer input (a modification that…
