3D Printed Cases For TinyTX and Tiny328

Another post I’ve been meaning to write for a long time. I finally got my Rigidbot 3D printer in August 2014 some 9 months later than the estimate but I was one of the lucky ones, many had to wait a lot longer and some have even had to pay extra for delivery, having already paid it once as the company […]

Wireless Sensor Battery Life 3+ Years On

I last blogged about this in December 2013 when the second version of my ATmega328 & DS18B20 based temperature sensor, installed on 29 December 2011, had just reached the 2 year mark on the original set of batteries. That’s pretty good going and I’d have been happy with that but how long would it last until those Energizer batteries […]

X10 and Home Easy with Node-RED

This is part of a series of posts I am doing describing some of the things I have been doing as part of the revamp of my home automation system. When I started on the home automation road in 2002 I began with a kit of 3 X10 modules and a CM12U PC interface which I […]

TinyTX & Tiny328 Sensors with Node-RED

Node-RED is currently taking the IoT world by storm, described as “A visual tool for wiring the Internet of Things” it is built on top of Node.js and is an open source project developed by IBM employees. It makes it easy to link various inputs and outputs adding simple or not so simple processing in […]

Tiny328 – A mini wireless Arduino clone

So here is the reason for the last couple of blog posts. This is my first venture into designing an SMT board and apart from the practice run I did with some breakout boards it is the first time I’ve attempted to solder anything as small as a TQFP package or the tiny 0603 passives (1.6 […]

OSWIN Gateway with RFM12B, SRF and OOK Support

So after getting an SRF based TinyTX and an OOK based one running I thought I should update the gateway code for my OSWIN gateway to support both types of sensors as well as the RFM12B. To receive the SRF node I’m using a Ciseco XRF in the Xbee socket and the OOK receiver is plugged in […]

Using a cheap OOK radio with the TinyTX

Going the opposite way to the last post this is a version of the TinyTX wireless sensor node using a very cheap radio setup. I first experimented with this 433MHz OOK/ASK radio pair a few years ago with an ATmega328 and the VirtualWire library but I never did much with it beyond a simple demo and […]

Using the Ciseco SRF with the TinyTX

I’ve been meaning to get round to this for a while. I bought one of Ciseco’s SRF transceivers when they first came out in October last year but didn’t get round to trying it until a couple of months ago when there were rumours of the RFM12B being discontinued and while that isn’t the case […]
