I2C OLED and output for TFT+touch
IR RBG LED Strip Arduino Controller
Full build and instructions on [Youtube Video] or [Instructables.com]
LED controller for LED-strings, -strips and -rings with individually addressable LEDs.
The controller offers a wide spectrum of usefull functions:
- I²C front panel connector for a on display UI and rotary controller.
(for use with DUPPA.NET's I²C rotary controller and a I²C OLED Screen)
- WIFI AP AND Standard Mode, for use with and without existing Wireless network infrastructure.
> I got a lot of messages about the project, or the code, but the situation was I put the project on hold for a while, when waiting for parts to arrive, then modified multiple times without documenting etc... the project got finished working well, heat up quickly, but when I have time I will make a fully documented mark 2 version.
AxH is an Italian Community of homebrewing passionates.
AxHTherm is a smart device born to help home brewers to take control of their fermentation chambers.
It allows to define temperature steps, temperature ramps, and gravity set points to guide your fermentations!
You don't have to be nearby your fermentation chamber anymore! With AxHTherm you can remotely manage your fermentations, and trac...

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...
Controller for the **LinuxCNC** (Ethernet + STM32). This project is in progress. Schematic isn't tested yet. Use carefully (:
- Fast and powerfull STM32 microcontroller (STM32F429IGT6, 180MHz)
- Ethernet 10/100 connection with any PC or ARM board
- 6 output channels of PWM/step/direction/enable (steps rate up to 2 MHz)
- 6 inputs channels for ABZ encoders (TTL5V and differen...
This is a basic firework launch controller based around an arduino nano/ micro. It can also be used to controll any dc appliance in a timed sequence, up to 24A/10A. The boards are designed with osome costumizability, as it is'nt a completeed project (there will more then likely be a v3.0) and has a lot of unused pins on ics and connectors.
