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.
More compact speedometer with OLED display and temperature measurement.
This is the version 2 of the ATtiny85 speedometer. It features an ATmega328p uC that has more memory, pin functionalities, higher frequency and to which you can easily find the needed libraries (the ATmega328p is used on Arduino Uno). A serial-to-USB converter is needed for programming. It has the previous version's batte...
ATtiny85 controlled FM radio with RDS (RDA5807) and integrated audio amplifier (XPT8871). You can directly connect a protected li-ion battery, a 3 W / 4 Ohm speaker and an FM antenna.

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...
