Christmas tree ornament with (mostly) just a small number of through-hole components. Great for beginners. Might need a more experienced person to install the ATTiny841 and program it. There is an (optional) programming header to make in-circuit programming easy.
Unlike lots of other similar projects, the use of a micro-controller allows for smooth fading of the LEDs which makes for much more nat...
# Watering System #
This is a simple **wat**ering **sy**stem based on ATTinyX5 MCU.
Note: this project is intended to be powered by a 3xAA battery pack and a CR2032. The MOSFETs used in this project might not be able to dissipate power from voltage-stabilized source. This case was not tested.
The components are
- Control board (this project)
- 3V-6V powered DC motor water pump with flyback dio...
# Auto light
Attiny10 & APDS-9930 based automatic light/switch
This project utilizes small ATtiny10 mcu to work with APDS-9930 ambient light (AL) and proximity I2C sensor.
This is used for automatic "smart" light in a drawer. Once the drawer are open the APDS-9930 will notice proximity change
and trigger a pres...

ПРИНЦИП РАБОТЫ УСТРОЙСТВА
— очень прост – подаем на плату 12 вольт, вставляем в панельку «запорченный» микроконтроллер, нажимаем кнопочку «START» и через доли секунды получаем новенький рабочий микроконтроллер. Очень просто, даже не нужен компьютер (всегда возмущают псевдо навороты, в виде управления при помощи специальной программе на PC, там, где это в принципе...
This project was made as a challenge to see how small I can go with conventional soldering techniques, this uses an Attiny85 with a QFN-20 package.
Este es un proyecto para ver que tan pequeño podía diseñar un circuito y culminarlo con soldadura convencional. Usa un Attiny85 con empaque QFN-20.
This projects is a device controlled thru i2C, it has a set of instructions to control two leds, two buzzers and a combination of them.
The device uses an ATTiny85 and it connects to an RaspberryPi to send the commands.
The instruction for the device are:
- 0x00 --> Does nothing
- 0x01 --> All Buzzers ON, All LEDs OFF
- 0x10 --> Al Buzzers OFF, All LEDs ON
- 0x11 --> All Buzzers ON, All LEDs O...
kcx bt003 (BT and usb flash) and arduino nano, to Ford Sony, with Steering Wheel button controls.
Arduino reads wheel buttons and says BT what to do, next or prev track on phone or usb flash.
Buttons on PCB its volume up and down.
Quick-and-dirty little circuit to switch a garbage disposal from a low-voltage momentary button. PCB fits into junction box. For supporting files, refer to https://github.com/gutschke/garbagedisposal
I couldn't find all the parts that I wanted from LCSC. For now, I linked to DigiKey parts. If you have suggestions for suitable substitute parts from LCSC, please let me know.
I made reasonable acco...
