Beaglebone black based heating controller
BBB based heating controller
[22 Aug 2016]
I fixed the ULN2803 package and GND on P20. Still need to investigate if there is a pull down resistor needed for Q1
Issues found during assembling the PCB:
- ULN2803 package is incorrect - it should be SOIC18. I will correct the PCB soon
- GND pin in the P20 5V/12V connector is not actually connected to GND
- The heartbeat LED is on...

Overview:
ESP32-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
At the core of this module is the ESP32-D0WDQ6 chip*. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individu...

ESP8266 Sensor Board
This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...
Solar panel li-po low power charger for esp8266
Solar system power for esp8266 device like weather sensor. You need 5V 0.15W solar panel and small li-po battery for example 200mAh. Zener diode stabilizes voltage on 4.3, schottky diode give 0.15-0.2V voltage drop because 4.3V is too much for li-ion battery and prevents lekage current from battery. You can use panel also like binary(0/1) light sensor.

ESP8266 RGB LED-Controller
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...
OneCellLight
ATTiny 25/45/85 & WS2812/PL9823 breakout board powered by an AA cell.
I also use the board lightly modified with a LDR as a firefly simulator and with a radio module as an IOT sensor.
SKETCH
Preliminary edition of the hardware platform for Ethernet connected IoT devices with configurable additional ESD protection. Has 40 pin application interface. Based on STMicroelectronics STM32F405RGT6 microcontroller and Microchip ENC28J60 IEEE 802.3 controller.
Order the design to me.
RGB Headboard Lights
RGB PWM controller. Uses ESP-01 to control the colour of the Leds. Uses MQTT protocol to connect to my smart home server to be controlled over the network.
