AVR Programmer Shield


ohneschuh @ instructables.com has build a Arduino Shield that is able to program spare ATmega328 and ATtiny85 mcu using the ISP sketch.

Beside my Arduino instructables I also use pure ATmega328 and ATtiny85 microcontrollers. To program them I normally used a breadboard and the ArduinoISP setup with an Arduino UNO or NANO. But this was not the best solution.

So I build this programmer shield in my typical stripboard layout: Only straight lines – no crossings!

ATtiny 85 EMF detector


arduinomaster @ instructables.com has build an EMF detector based on ATtiny85 mcu able to detect signals from 0-999Hz. He writes:

An EMF meter can measure AC electromagnetic fields, which are usually emitted from manmade sources such as electrical wiring, while gaussmeters or magnetometers measure DC fields, which occur naturally in Earth’s geomagnetic field and are emitted from other sources where direct current is present.

ATtiny85 and SSD1306 wearable display

How to make wearable display – OLED SSD1306 display run by ATtiny85

Step by step tutorial, with no steps to skip.

The main goal of this tutorial is to show how to make wearable display run by Attiny85 and OLED display SDD1306.

Due to running campaign for ATtiny25/45/85 PCB TINY CHEAP VERSATILE Arduino compatible on Indiegogo I did prototype of wearable display base on natural leather, to show what is possible with ATtiny25/45/85 PCB.

How to program the ATtiny85 with the Arduino UNO board


by codebender_cc @ instructables.com:

In this tutorial we will use an Arduino board as an ATtiny programmer.

To do this we will use one Arduino UNO board as an ISP (programmer) and one ATtiny85 micro-controller.

We will use Codebender – online Arduino IDE.

With the following procedure you will be able to program easily the ATtiny45 and ATtiny85 micro-controllers.

ESP8266 + Attiny85 + DHT22 Temperature/Humidity Logger


by guibom @ github.com:

Basic ESP8266 + Attiny85 + DHT22 Temperature and Humidity logger. I’ve made this to experiment a bit with the ESP8266 wifi module, and hopefully make a remote sensor that posts the data to my server.

I wrote the code to work with both an atmega328 and a attiny85. The mcu sleeps in between readings, consuming about 35uA while powered down (the ESP module, even when chip-disabled, is responsable for about 80% of that).

The UDP messages are very specific to my use case; I have a node-red UDP listener that receives JSON strings from the logger and forward them as MQTT messages. But it should be very easy to change it to send whatever you might need.

Mini weather station with Attiny85


by diy_bloke @ instructables.com:

In a recent instructable Indigod0g described a mini weather station that works pretty well, using two Arduinos. Maybe not everyone wants to sacrifice 2 Arduinos to get humidity and temperature readings and I commented that it should be possible to do a similar function with two Attiny85’s. I guess talk is easy, so I better put my money where my mouth is.

Musical holiday card using microSD card


by Dmitry Griberg @ dmitry.gr:

You’ve probably seen various holiday or birthday cards that play a little jingle via beeps when they are opened. Last few years have brought new ones that play actual sampled music for a dozen seconds or so. I decided, for this new year’s celebration, to make a card that, when opened, will play a complete song in full fidelity. And the song it should play should be selected randomly each time of many. The project would be housed in a normal CD jewel case. The project was further complicated by the fact that it is impossible to predict shipping times during the holidays. Thus the task was to do all this, using nothing but whatever materials and components that I already had at home. I managed to do this successfully, and the project worked well. It is not the best designed or the most efficient, but it does work.
