Breaking all the rules to create an arbitrary clock signal
Have you ever needed a clock speed that wasn’t easy to generate? What if you wanted to build and run your own PLL? Within an FPGA?? As an example, many of my favorite FPGA boards have 100MHz clocks coming into them.

Evolutionary FPGA Simulation on DE1-SoC
Our ECE 5760 Final Project uses the Terasic DE1-SoC’s Cyclone V FPGA and Cortex-A9 cores to fully simulate a Xilinx XC6200 FPGA. We test the functionity of the hardware-simulated FPGA and experiment on its ability to discern between input frequences using a genetic algorithm.

SKiDL
Never use a lousy schematic editor again! SKiDL is a simple module that lets you describe electronic circuits using Python. The resulting Python program outputs a netlist that a PCB layout tool uses to create a finished circuit board.

FPGA Soft CPU Is Superscalar
We will admit it: mostly when we see a homebrew CPU design on an FPGA, it is a simple design that wouldn’t raise any eyebrows in the 1970s or 1980s. Not so with [Henry Wong’s] design, though. His x86-like design does superscalar out-of-order execution, just like big commercial modern CPUs.

Copy Protection In The 80s, Showcased By Classic Game Dungeon Master
Making a copy of a purchased game used to be as simple as copying a disk. As the game industry grew, so did fear of revenue loss which drove investment in countermeasures.

Booting The Game Boy Advance Into Bluetooth
While it might not be quite as revered as its predecessor, the Game Boy Advance is arguably the peak of “classic” handheld gaming, before things got all 3D and dual screen on us.

Dumping Commodore 64/1541 Disks with Errors
Many old Commodore 64/1541 disks have read errors, but this doesn’t mean the data isn’t recoverable – with the right nibtools settings and some cleaning. The ZoomFloppy adapter is the de-facto standard for connecting Commodore disk drives to modern computers, using a USB connection.

A Tetris Clock
We have had no shortage of clock projects over the years, and this one is entertaining because it spells the time out using Tetris-style blocks. The project looks good and is adaptable to different displays.

RPi – IoT Weather Station
On this tutorial we will get data from several different sensors, sending them to an IoT service, ThingSpeak.com and to a mobile App (Thingsview), where we can log and play with data. We will explore several different communication ways of connecting sensors to a Raspberry Pi, as:
