OH HAI! on Windows 10 IoT Core

Oh, Hai Hai ('hi') is an integration point for several stand alone smart home technologies.  Hai runs on the Raspberry Pi and can be adapted to optimize electricity consumption (lighting/HVAC) and water usage (irrigation/rain collection) in a number of ways. Hai was originally envisioned for any Pi running Raspbian OS, but is also being ported over to utilize the new Windows IoT Core on a Raspberry Pi 2. Th ...

Persistence Of Vision

Persistence of vision is an optical illusion, it works on a simple phenomenon how our day to day television works. MY first pov was six months before with arduino uno and with motor. However it is best to have a small and portable device that can be carried anywhere and image can be seen without any external motors or fan. This small portable pov version uses attiny 85 ic, smaller variant of arduino uno tha ...

3D-Printed RGB Wallet

Stand out from the crowd with this unabashedly ostentatious excuse for a wallet. It's got plenty of space, RGB lights, and you can even put your name on it for added vanity. Interested? Keep reading! In the files section of this build you can find two things: a Fusion archive and some STL files. If you're just interested in printing a blank wallet without any text on it then download the STL files. Load the ...

nRF24L01+ with ATtiny85 3 Pins

This would be the continuation of my previous project Programming ATtiny85 with Arduino Uno. Now with cheaper ATtiny85 in place I was looking for cheaper ways to transmit the sensor data. Which brought me to nRF24L01+ a cheap, low power RF transceiver. This seemed to be the better solution for me. But there was one problem, limitation in number pins in ATtiny85. I can't connect both nRF24L01+ and the sensor ...

LED step-up converter with ATtiny85

Build a cheap and simple full software controlled step-up (boost) converter to drive a LED string of 10 LEDs. LEDs are used as string to light up a acrylic engraved plate placed in a holder (also made out 5 layers of lasered black acrylic glas). Step up is from 5V to about 30V, current regulated to about 20mA. Poti is for software features only. Current is measured by voltage at 10 Ohm resitor feedback to u ...

Mini weather station with Attiny85

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. In fact, if I combine two earlier instructables I wro ...

ATtiny85 Two-Channel Lead Acid Battery Charger

Winter just arrived. The enemy of all batteries. Last year this was the season the auxiliary battery of my T3 VW camper bus bit the dust. This likely happened because I neglected to take care of it over the winter months during which the bus is typically parked in my garage. When the auxiliary battery is really dead dead, aka croaked, it is not only not working, but it also prevents the main battery used fo ...

Stripboard Arduino shield for programming ATtiny45 and ATtiny85

This instructable (entered in the Arduino Challenge contest - you can vote for it above) shows how to make a stripboard Arduino shield for programming either ATtiny45 or ATtiny85 microcontrollers with an Arduino, as per these tutorials from the High-Low Tech group at MIT: Arduino board as ATtiny programmer Programming an ATtiny w/ Arduino 1.0 The top link shows a breadboard arrangement for the programming s ...

How to make and use the arduino as an Isp for an ATtiny85

In this instructable I will show you how you can make your own Atting programming shield for the arduino and then use the arduino as a programmer. Usually If you don't have a shield you can do a breadboard version to program the ATtiny. (Step1) But here I'll show you how to program it and with a couple of components make a nice shield for the arduino, which makes programming much easier! For more informatio ...

Arduino decision box (Attiny85)

So I was a bit bored this weekend (actually I wrote this some months ago) and since I had ordered a bunch of Attiny85 chips the week after I decided to make a quite random project with them. This is a decision box, it takes decisions for you by showing a green or a red light (it can also show orange if we programmed it to combine both colors). It's made from wood and it has an aluminum plate to cover it all ...
