SSD1306xLED Tinusaur ATtiny85 Library for SSD1306

Story SSD1306xLED is a C library for working with the SSD1306 display driver to control dot matrix OLED/PLED 128×64 displays. It is intended to be used with the Tinusaur board but should also work with any other board based on ATtiny85 or similar microcontroller. The 128×64 OLED is controlled by a SSD1306 circuit and could be interfaced over I²C. The code could be divided in 3 pieces: Communication over I²C ...

Open Source IoT Platform

The Project Intended as open source for those who want to build their own dosimeter with their own tools, this is an IOT device that can take several sensors and have the data centralized online. The readings are accessible via a RESTful API, or by connecting directly to the KIT1 unit, in the local LAN. This is useful when you want to monitor several locations, and plot charts or analyze the data. By defaul ...

Goldilocks Analogue – Prototyping 3

Following my initial design article, and the follow up design article, I’ve put quite a lot of thought into how I can make this Goldilocks Analogue device best achieve my stated goals. Pictured is the new 3rd Goldilocks Analogue Prototype. I'm now working on the 4th Goldilocks Analogue Prototype. The PCB layout has been completed, and we're talking about how to produce it with a view that this will become t ...
