This project creates a RGB LED lit love heart which is controlled by a PIC12F683 microcontroller.  I designed the project as a gift for my wife on our 15th wedding anniversary (since she puts up with my addiction to electronics I thought she deserved something in return!). The love heart is made from a 200x150x6mm […]

Lissajous Figures on 8X8 Led Matrix

Lissajous Figures on 8X8 Led Matrix

A point of light oscillating in 2 perpendicular axes draws a pattern named “Lissajous Figure” (1857) or “Bowditch Curve” (1815). Patterns range from simple to complex depending on the frequency ratio and phase of the 2 axes.A 1:1 ratio with 0 phase difference draws a straight line at 45° angle. In this project the frequency ratio of the 2

DMX 512 to Serial Adapter

DMX-512 to Serial Adapter

This device reads a DMX-512 signal and grabs a variable amount of channel data values and sends them at 57200 or 19200 baud to an external device, such as a 24 Channel High Current LED Controller, when a new data packet is requested. This allows any microcontroller(PIC, Arduino, ATMel, ect.) with TTL serial communication to accept

TINY OBSIDIANBOA DEV BOARD FEATURES ESPRESSIF SYSTEMS’ ESP32-S2 BOARD

Greg Davill has posted on GitHub an Espressif Systems ESP32 based development board called the ObsidianBoa. Recently Greg Davill had a successful OrangeCrab crowdfunding campaign, he has however directed his attention to the Espressif Systems ESP32. There are a lot of ESP32 development boards today in the market, however, there is only a handful with a tiny form factor, like the
