T12 Quick Heating Soldering Station featuring
- Temperature measurement of the tip
- Temperature control via rotary encoder
- Boost mode by short pressing rotary encoder switch
- Setup menu by long pressing rotary encoder switch
- Handle movement detection (by checking ball switch)
- Iron unconnected detection (by idenfying invalid temperature readings)
- Time driven sleep/power of...
This is my atmega8 (and ATmega328 compatible) development board.
As it has the uart connector, you can program it in the arduino ide, if you are into that. You just need to download the bootloader through isp programming.
(I personally prefer to do it the expert way)
I added some connectors according to what I usually use:
I2C (also pull ups)
SPI (with an extra pin for devices such as nrf24,...
ATtiny controlled and LiPo battery powered MP3-Player using the DFPlayerMini-module featuring:
- Micro-SD-card slot,
- battery charging and protection circuit,
- battery level detection,
- OLED display,
- on/off switch,
- volume control,
- 3 push buttons to control the player.
You can directly connect a 3.7V LiPo battery and a 3W/4Ohm speaker to the board.
The firmware is written for the folder-p...
Small version of the famous Transistor Tester developed by Markus F. and Karl-Heinz Kübbeler featuring automatic detection of NPN and PNP bipolar transistors, N- and P-channel MOSFETs,
JFETs, diodes, double diodes, N- and P-IGBTs, thyristors, triacs, inductors, resistors and capacitors.
|Resistors|100mOhm – 50MOhm|

TinyLoad is a simple electronic constant current dummy load. The ATtiny85 measures voltage, current and temperature of the heat sink, calculates power, energy and battery capacity, controls the fan and displays all relevant data on the OLED. The button is used to switch between power/restistance and energy/capacity display.

This is a Raspberry Pi Zero W hat/shield with USB MIDI input, stereo audio output, 3 user-configurable buttons and OLED display.
To use as an audio card, enable PWM audio output by adding `dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4` at the end of *config.txt* file.
Remeber that HDMI audio output is the default; use `raspi-config` to force output to 3.5mm audio jack.
If you can't find 47uF...

The ATtiny85 USB Phone Charge Guard controls and monitors the charging of phones and other devices. Voltage, current, power and energy are constantly measured via the INA219 and compared with the user limit values. It cuts off the power supply via a MOSFET when a condition selected by the user is reached. The user settings are saved in the EEPROM.

Compact speedometer with OLED display and temperature measurement.
It features an ATtiny85 uC with USB programming and battery charging and protection circuitry. I will be using it to measure the speed of my bicycle and determine the temperature around me on my rides.
The project consists of 2 pcbs: the sensor that will be mounted on the wheel of my bike and the actual speedometer.
