1.5V battery powers white-LED driver
https://www.electronics-lab.com/1-5v-battery-powers-white-led-driver/
Although white LEDs are common in a variety of lighting applications, their 3 to 4 V forward-voltage drop makes low-voltage applications challenging. Charge pumps and other ICs are available for driving white LEDs, but they generally don’t work with the low supply voltage of 1.5 V in single-cell-battery applications. The low-voltage circuit of Figure 1 provides […]
Homebrew DMX-controlled RGB LED light
https://www.electronics-lab.com/homebrew-dmx-controlled-rgb-led-light/
Glen has written an article detailing his homebrew DMX-controlled RGB LED light: This project is a small DMX-512 controlled, color-changing RGB LED light. The light can be controlled via the DMX512 protocol or it can run a number of built-in programs depending on how the software is configured. The light incorporates an advanced 16-bit PIC24 microcontroller with […]
USB Stack Light Controller based on PIC16F1459
https://www.electronics-lab.com/usb-stack-light-controller-based-pic16f1459/
Glen Akins build a USB Stack Light Controller based on PIC16F1459 and documents the process on this personal blog. He writes: After using the PIC16F1459 to build numerous USB HID input devices including a giant keyboard, a tiny keyboard, and a big red button, it was time to see if the PIC16F1459 could be used […]
