Everybody wants to give FPGA development a try and here’s a great way to get into it. You can build your own Persistence of Vision display using a $30 dev board. It’s a fun project, and you’ll learn ...

The Flipper Zero can do all kinds of neat stuff, like helping you cut keys or decode various radio transmissions. However, until now, it hasn’t been particularly adept at persistence of vision tasks.

Persistence displays retain waveform traces on the screen, allowing them to decay over a user set time duration, they allow users to see a history of signal variations on the screen. This feature is ...
