ATtiny OLED Watch Core

FDE7JXRIILZRAY9.MEDIUM

陳亮 @ instructables.com shows us his ATtiny85 OLED display build on a breadboard:

This instructable show how to use an ATtiny85 to create a tiny watch core that can run over 1 year before recharge or replace battery.

The instruction to make the watch case may be in next instructable.

I have made a few Arduino watch before, but I found the watch using ATmega boards or ATmega chips are a little bit too big to wear. So I would like to make it with a smaller chips.

ATiny does 170×240 VGA with 8 Colors

main

AtomicZombie @ avrfreaks.net used an ATtiny85 ATMEL microcontroller to produce a 170×240 VGA signal and also send audio along with video.

The original plan was to just bit bang some mono VGA and do up a Pong or Tetris game, but things went MUCH MUCH further than I ever thought possible, so over the next few weeks I will detail this fun project here. I call it The QUARK-85 VGA DEMO System.

So what can one do with an ATTINY-85 and no other external components, an 8 pin package that leaves ONLY 4 IO lines after you feed it a clock??

How about 4 color rock solid VGA with stereo sound!!!

MagSpoof – Wireless credit card/magstripe spoofer

magspoof

MagSpoof is a device that can spoof/emulate any magnetic stripe or credit card you currently own. It can work “wirelessly”, even on standard magstripe/credit card readers, by generating a strong electromagnetic field that emulates a traditional magnetic stripe card.

Note: MagSpoof does not enable you to use credit cards that you are not legally authorized to use. The Chip-and-PIN and Amex information is not implemented and using MagSpoof requires you to have/own the magstripes that you wish to emulate. Simply having a credit card number and expiration is not enough to perform transactions.

AVR Programmer Shield

F9HXII0IH3T87N2.MEDIUM

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

F9EA26GIGZIZHK0.MEDIUM

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.

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

FBKHKPPIFMTRL67.MEDIUM

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

FXFROUOIA3YJYFN.LARGE

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.
