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.
maualy fire any channel
> 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.
4 steppers direct ESP32 GPIO and 2 via I2S shift register
shift register PWM for 4 mosfet, 4 servo outputs
mixed voltage: two power rails
current and voltage monitor for two power rails and IC power
all parts available through lscs.com
I2C OLED and output for TFT+touch
ATtiny85 IR remote LED controller - mainly for ambient light behind a TV
Single colour LED
On first power up
Press PROG button to enter program mode
Programming can be over written once the PROG button is pressed
Press ON/OFF assigned button
LED fades in to set brightness value
Default to 50% 
Once the di...
Seconsor controlled relay to be used for pump, main switch etc. S1 switch to be replace by magnetic water sensor (sump), photocell etc. For sump (drain pump) a timer might be needed to delay the start. This depends on the lenght of the sensor.
STM32 RGB generic control module (the one found on the cheap online retailers). Paths and some parts may not be accurate as they do vary, but the schematic was recreated based on the P9813 datasheet for the +12V power source. Note that this chip takes in power from 9V all the way up to 30V or so (check datasheet for specifics), and that the paths/chip locations are not perfectly representative of...
This electronic system is used in staircases or some other places where it is needed to have an automatic light switching controller. It's a device which turns on the light only when there is dark around and the switch is pressed. It will be turned off after the high state on the output of 555 has been over, according to the formula: t=1,1R2*C5. If you want to control some LED eg. COB instead of s...
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...
