These days IR remote control is still the cheapest option for consumer electronics. I've long had the idea that Forth is ideal for scripting IR remote-controlled devices and I used the light bulb at my desk to learn how to do that with STM8 eForth. LED lamps of relatively high quality with a combination of white LED and RGB LEDs have a remarkable low price tag: the set below costs no more than a regular white LED lamp. In my experience service life is much better (maybe due to a switched mode power supply with constant DC voltage and µC PWM control). The option for occassional colorful illumination is a bonus.
This writeup covers analyzing light bulb IR remote control codes and using it with STM8 eForth . The code below also is a showcase for the expressive power of STM8 eForth on a cheap 8bit µC (e.g., STM8S103F3P6 w/ 8K Flash and 1K RAM).
