A Saturday morning puzzle on my FPGA

I woke up this morning with a desire to solve a puzzle. I decided that I'd make a simple LED chaser on a 7-segment LED display using my Mojo FPGA (now that I have everything working in Windows 10 again…

Pong on the Mojo Revisited

In my previous post, I briefly discussed the implementation of a pseudo-pong game on my Mojo FPGA developer board. I was able to implement the VHDL version that I linked to later in the post and it works much better.…

Creating PONG on the Mojo FPGA

I recently found an old VGA monitor on the side of the road and it inspired me to see if I could get my Mojo FPGA board to output a VGA signal. I took the monitor apart and wired its…

Custom Fritzing part for Mojo v3

There is a great tool called Fritzing that allows you to create a breadboard view of circuits that you can use for documentation. I really wanted to use it to document the breadboard for my post on setting up a…

Reversible Binary Counter on the Mojo FPGA

After playing around with the Binary counter implementation from a previous post: Implementing a simple binary counter in the Mojo FPGA IDE, I wanted to make the LEDs display a count down in response to a switch position. I decided…

How I accidentally learned something unexpected from a simple binary counter

In my previous post, I talked about how I implemented a binary counter with my Mojo FPGA board. I am working on a follow-up post on implementing a reverse binary counter with a switch that lets you change between the…

Implementing a simple binary counter in the Mojo FPGA IDE

I recently purchased a Mojo FPGA development board based on the recommendation of my good friend Keith Rome. He's been very helpful in getting me started on my journey into this bizarre technical realm. I've also had a lot of…

I have been a computer nerd since I was ten years old. I begged my parents to buy me a computer for Christmas. In 1982, I was the proud owner of a Texas Instruments TI-99/4A. I've been coding since.
