Very simple power board for a Wemos D1 to power a strip of LED's aimed to be used together with the WLED software project to control the strip.
Work In Progress and **NOT** tested yet, use with caution!

Custom instrument cluster utilizing LED and LCD displays for visual effects. Connected into internal OBD bus and PCM. Additional feed provided through GPS for geo-location, tracking and control is sent via SMS into phone or web server.
A ESP-12 IoT controller for RGB LED Stripe 5-12V.
3+1 channels through MOSFET, PWM and dimming functionality.
The MOSFETs can be replaced by NPN Power transistors (input resistors are as THT parts placed, the 10k pull down's not needed.
The 4th channel is a Logic level up-converter (3.3V->5V). Driven by a 2N7002, can be replaced with BSS138 or similar. Note that it's is a very small power output...
A dual microcontroller board for controlling "Neopixel" LEDs, with one micro dedicated to driving the LEDs while the other micro is busy reading push buttons, polling rotary encoders, reading IR remote signals etc etc.
The microcontrollers -two atmega328s -communicate with one another over their I2C bus. The very short wire run negates the need for the usual pull up resistors on the bus.
Change Log :
- More room for capacitor for being couched (flatter design)
- No more voltage divider on VESC Tx (VESC MCU is 5V tolerant)
- No more resistor for WS2812 Data line
- Pin mapping changed
- "SmartRing" label added
- "CH3" label changed to "PPM"
- Connector for BLE module (HM10) added
- Additional Switch button added
- Labels for identifying pins on IO, PPM and BLE connec...
An IoT board around ESP-12S module (with ESP8266) powered by a 9V-26V DC jack, with 3 signalling WS2812 RGB LEDs, 2 buttons, an OLED display, a beeper and an I2C temperature & humidity senzor (AM2320). The board is meant to act as a hub and connect to other devices with more sensors, or as a driver for an external device.
