Wireless digital scale

F9IVS3JIO7EMPYQ.MEDIUM

This is a wireless digital scale using ATTiny85 microcontroller and HM-10 Bluetooth low energy transmitter/receiver:

This scale is wireless. It may be useful where you can’t operate a normal scale, due to the weather outside, or if you don’t want to scare birds or other creatures away. With this scale you can weigh them. In this instructable, I used a 0 to 1 Kg load cell since I wanted to weigh hummingbirds and orioles that visited our nectar feeder.

ATtiny85 Boost Converter

FAAOBO2IO6DZTEB.MEDIUM

GreatScottLab @ instructables.com build a step up dc-dc converter with the help of ATtiny85 microcontroller.

In this project I will show you an efficient and common way how to step up DC voltages. I will also demonstrate how easy it can be to build a boost converter with the help of an ATtiny85. Let’s get started!

USB Power Meter

8347081450814343498

Daniel Grießhaber @ hackaday.io has published his build of a USB power meter. His device is based on ATTiny 85 mcu and 0.96″ OLED Display and is able to measure voltage, current and power output from USB port.

Since USB has become more and more a power delivery standard, it would be nice to have a convenient way to measure the power consumption these devices need. Of course there are already power meters out there, but they are just boring or don’t have all the features I like.

Programming an ATtiny with Arduino board

Screen-shot-2011-06-06-at-1.46.39-PM

This detailed tutorial shows how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software.

The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. It does, however, have some limitations relative to the ATmega328P on an Arduino Uno. There are fewer pins, meaning you can’t connect as many components.

ATtiny85 Game Console

IMG_0165B

webboggles.com has designed a SSD1306 OLED Screen based game kit using an ATtiny85 microcontroller. They also sell it as a kit to assemble it yourself.

The new snap case has been updated to allow enough height for the screen header as well as a factory made CR2032 battery holder.
The buttons have been concealed to prevent spontaneous button presses inside bags and pockets.

ATTiny85 board A First Look and review

educ8s.tv wanted to take a look at this tiny board for a long time. It is very small size, it is low cost and it uses a different processor than the Arduino boards. It uses the ATTiny 85 microcontroller chip, which can operate at a frequency up to 20Mhz. It has 8Kb of flash memory, 512bytes of RAM memory and 6 I/O pins 2 of which can implement the I2C protocol. It is very small in size and has low power requirements. We can program it using the Arduino IDE, which makes things so much easier! I got this tiny board with a USB interface in order to be easier to program. You can find a link for this ATtiny85 board in the description of the video.

educ8s.tv wanted to test if the ATtiny85 board is a good option for simple projects and if we achieve longer battery life with this board that a standard Arduino mini. Let’s find out together.

Polyphonic Synth Cable

Polyphonic MIDI Synth on an ATtiny2313:

This is the fourth synthesizer cable I’ve built, the first three being based on the ATtiny85. I have been looking into ARM chips but haven’t gotten to grips with them just yet. Instead, I decided go back to the ATtiny2313, which has a quarter of the memories of the tiny85, but a hardware UART port and more pins.

DIL-Duino – Arduino in a DIL shape

3895531450822949600

DIL-Duino is a complete Arduino environment in a DIL-8 form factor based on the DigiSpark Hardware. by Daniel Grießhaber:

DIL-Duino uses the QFN Version of the ATTiny85 and a USB Bootloader to provide the easy to use Arduino stack in a single DIL-8 Package Footprint.
To fit the Micro-USB socket on the board, it was necessary to make the actual board bigger than the DIL Package, but after development the Board is perforated to break the USB Socket and get the desired footprint.

DIY Wearable Posture Sensor

IMG_6986

With the help of this wearable device you can improve your posture as it will remind you whenever you slouch. The device is based on ADXL335 accelerometer and Attiny85 microcontroller and a vibration motor will get you notified.

Posture sensors/monitors have been a recurring theme on this blog. They are supposed to remind you of your posture and prevent you from slouching, which can be a cause for back pain and headaches.While my previous sensors were either fixed to a chair or desk, this time I wanted to create a wearable version, that would allow for free movement. As always, one of the main goals was to make this project cheap and easy to reproduce.

ATtiny85 Ring Watch

FUWFMUQIKFQ06NI.MEDIUM

This is a great ATtiny85 watch that uses a SSD1306 OLED display and is powered by a CR1220 battery.

Today core subject, ATtiny85. Someone suggest me to use SOIC version to reduce the watch size and I found the coin cell mAh calculation method will count the battery voltage down to 2.0 V, so this watch require a low voltage version MCU to keep it stable. So I have ordered an ATTINY85V-10SU. (much expensive $_$)
