Using Node-Red with Ciseco LLAP devices

I’ve been using the Ciseco wireless modules for a while now and after seeing Node-Red I wanted to use the Ciseco modules as both an input and output to the nodes. This post describes how to setup the Serial In and Serial Out nodes to use either the USB SRF Stick or the XRF and […]

Max1284 – The next step for opensource IoT Gateway

I’ve been helping with a small project over at to produce a cheap, modular Internet Of Things gateway. Progress can be followed on its dedicated page. So far it has support for a number of wireless connections including RFM12 for Jeelab related sensor nodes, XBee and XRF. The data, once collected can then be […]

A Slice of Pi – Interfacing the Raspberry Pi

Having recently acquired a Raspberry Pi on loan for a few days I decided to try some interfacing. The simple solution would have been to put together a cable and header plug to connect to the I/O pins on the Raspberry Pi. This would need a custom circuit each time I wanted to try something. […]

The basic code is able to run simple Basic commands and run small programs. What it lacked is a place to store programs […]

Remote sketch upload to Nanode

Recently I made a presentation to the Nanode application development weekend to demonstrate how to send a new sketch to a Nanode. The idea is that the nanode is a network connected device and with a small addition to the ENC28J60 library it would be possible for it to act as a simple TFTP server […]

Home-made Geek Advent Calendar

As I don’t normally get advent calendars myself I thought I’d do something about it this year. Instead of chocolate I’m using electronic parts that go to make up an breadboard based Arduino system, minus the usb to serial chip.

The main part of my advent calendar is made from two sheets of A3 foam […]
