TinyCalibrator is an oscillator calibrator and high-voltage fuse resetter for 8-pin ATtinys based on an ATtiny44/84. Because the 8-pin ATtinys only have a few GPIO pins available, they are usually operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, t...
TinyHVSP is a stand-alone high-voltage serial programmer and fuse resetter for ATtiny 13/25/45/85. This project was superseded by the more versatile [TinyCalibrator](https://github.com/wagiminator/ATtiny84-TinyCalibrator).

# TinyICOC - AVR In-Circuit Oscillator Calibrator
Sometimes AVRs are operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, the oscillator can be calibrated, increasing its accuracy to +/-2% or better. There are a few ways to perform this manual calibration, but s...
The device is an addition to the gas handle of the electric bike, simulating the operation of the controller in the current control mode. Smooth start after a long standing on the spot and at the same time a quick set of turns after a short-term gas release and subsequent increase. The signal level is reset instantly, and the rise depending on the previous state in time. Does not require a real m...
This is a charlieplexing PCB. The figure is a black cat sitting on an unicorn ([on reddit](https://www.reddit.com/r/blackcats/comments/7opy9u/and_lo_i_saw_a_rider_on_a_pale_horse_and_the/)). The artwork was made by inkscape and EasyEDA.

TinyPlayer is an IR remote controlled and LiPo battery powered MP3 player based on ATtiny13A and DFPlayerMini module. The DFPlayer module is controlled via a simple cycle-precise software implementation of the UART protocol (8N1, 9600 BAUD) in half-duplex mode. The volume last set as well as the track number last played are saved in the EEPROM and automatically loaded the next time it i...
This is little board I made to help me with ATTINY chips projects.
It has 6 pin USBASP input and 4 pin headers for each of the pin of the chip times 3, which makes it easy to connect oscilloscope and put it on breadboard in same time and still have pins to connect to it external device. Also it has both SOIC8 and DIP8 packages support.
Tiny little helper.
