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...

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...
