Project  ESPmeter

ESPmeter

“ESPmeter helps monitoring domestic gas consumption; a small device captures data from the gas meter which is then sent to a server via HTTP; a web application allows visualizing daily gas consumption with a granularity up to 5 minutes. Operating …

AVR ISP Programmer V2

“A programmer designed for easy programming of ATtiny13, ATtinyx5 series ATtinyx4 series, ATtiny2313, ATmega8 series, ATmega328, ATmega8515 Amtel AVR Microcontrollers come in a number of variants. The one most Arduino users know is the 28 pin ATmega328 variant. However AVR …

Snowflake Ornament

“Cute snowflake-shaped ornament with programmable LED sequence. Black solder mask and HASL finish complement this relatively small snowflake-shaped PCB. Powered by CR1220 3V battery in combination with ATtiny13 for easy LED sequencing. ISP pads are available to re-program the 6 …

ATtiny13-Based, Key-Controlled Simple Dimmer

“A tiny dimmer with corrected output for resistive loads. Controlled with 3 keys and showing current value on 8 tiny colored LEDs. Based on this project, I made a general purpose dimmer for incandescent bulbs or soldering irons with these …

A full-duplex tiny AVR software UART

“I’ve written a few software UARTs for AVR MCUs. All of them have bit-banged the output, using cycle-counted assembler busy loops to time the output of each bit. The code requires interrupts to be disabled to ensure accurate timing …

ATtiny13 TinyRemote SMD

“IR remote control based on an ATtiny13A powered by a CR2032 or LIR2032 coin cell battery. The code is a full implementation of the NEC protocol using only 370 bytes (36%) of program memory.”

Self-Calibrating USB Voltage/Current Meter

“With a code size of 1KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps. There are a lot of so-called “USB doctor” modules which are used for monitoring currents …

Animated Heart

“Just in time for Valentines day, a small gadget to be given to your sweetheart: a heart that loops through multiple animations. It nicely fits on a desk or table to have your loved one remember you! This animated heart …

Stopwatch with ATtiny13 and TM1637 LED Module

“A simple stopwatch. If you have 5v power source you do not need to build the LM7805 Voltage regulator circuit as in the drawing.”

The Cheapest and Simplest Pulse Counter

“This counter is made only from an ATtiny13 and LED diodes. Did you ever need a cheap and simple (with one digit only) pulse counter? This is the maximum optimization and simplification. Thanks to Charlie Allen.”
