Bellduino – The Internet connected handbell

I’ve recently been looking at alternative notification after seeing things like Bubblino created by Adrian McEwen, co-author of Designing the Internet of Things and the Cheerlights project from ioBridge labs. I had a gift ‘Ring for Beer’ bell that has been hanging around my desk for a couple of years now and decided to use […]

Over The Air Hackday challenge

I recently attended the Over The Air mobile development conference at the historic Bletchley Park, Home of the Codebreakers. This was a superb event including talks and hackday challenges covering a variety of categories. The challenge lasted just over 24 hours and in this time teams and individuals had to come up with something that […]

Programming Ciseco SRF LLAP Firmware

I’ve been using a number of Ciseco SRF Radio modules recently, including designing my own PCBs to produce temperature sensors and button sensors. The firmware used is for the XRF range of devices, but as they use the same chip, the firmware will mostly work. There are one or two exceptions, plus the fact the […]

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 […]

Simple Wireless Display using Ciseco RFu-328

The Idea

For a while I’ve been tinkering with the Ciseco RFu-328 Arduino compatible wireless module but hadn’t done much with one. I’d obtained a pair of 1.8″ SPI TFT displays via an eBay seller in China that I had previously used with Arduino and mbed modules. The displays are driven using the Adafruit ST7735 […]

Custom PCBs for Ciseco SRF Wireless modules

After my earlier experience of designing and having manufactured my own PCBs, I found I’d like to do more. This time using the Ciseco SRF surface mount wireless module. The company provide the EagleCAD schematic and PCB footprint for the module so it is a case of building the PCB around these. I did a […]

Using the Scrolling message display

Following on from a previous post describing the scrolling message display, I’m adding a few notes on how to use it with a service called If this then that (ifttt.com).

The idea behind IFTTT is tthat when an event occurs on one application or site it can trigger another application or event. There are a […]

mbed platform – FRDM-KL25Z

I’ve been using the mbed platform for a while now after receiving one to develop the IoT Gateway project. This was based on the NXP LPC1768 chip, the details can be found here. One of the downsides of this mbed was its price, even though the features are impressive for a microcontroller development board. Recently […]

The Coolcomponents 1Kg box of fun!

I recently spotted that Coolcomponents were offering a small number of 1Kg packages of cool stuff for the bargain price of £10. With the usual VAT and postage this was just under £20 for a 1Kg box of fun cool stuff that you’ve no idea what you’re going to get. The small number of boxes […]

Scrolling message display – From Meetup to Product

Introduction

I originally saw a demo of the Vodafone K3770 Mobile broadband dongle given by Ashley Mills of Vodafone at IoT London Meetup 9. In the demo the mbed was receiving SMS and outputting them to a printer. Shortly after this I got myself a Vodafone K3770 dongle and started to see what I could […]
