Particle Photon Batman lamp

Introduction

This project is to upgrade a basic looking Batman Lamp and create a WiFi Connected lamp. The original lamp was plain white in colour and not very interesting. The idea was to add a microcontroller with WiFi capabilities and a number of RGB LEDs. This is to be controlled via a MQTT message topic. […]

Home made reflow oven in use

Building the reflow oven is the easy part, but how do you use it to produce PCBs?

When getting PCBs produced, if you plan to build more than one board, then getting a stencil at the same time is a good idea. The one here is made from stainless steel. Using a flat surface, surround […]

Building a Reflow oven

I’ve recently had a need to produce a number of PCBs with a large number of surface mount components. After having struggled to hand solder the components, I decided to build a reflow oven and use solder paste. There are a number similar projects on the web, after looking at these I put together my […]

Arduino Yún WiFi Autobot Lamp

Introduction

This project is to create a WiFi Connected lamp from a Transformer themed lamp. The original lamp was plain white in colour and not very interesting. The idea was to add a microcontroller with WiFi capabilities and a number of RGB LEDs. This is to be controlled via a simple web page running on […]

Thing Innovations

Its been a little while since there has been any updates here, but I’ve mainly been working on the IoT Consultancy part of my company which is over at thinginnovations.uk. This is trying to work in the IoT area with new and innovative solutions. The first major project that I’m involved with is the Oxford […]

Resin.io and the OpenPi

Introduction

Following on from a previous post on Using Redin.io with Node-RED I have been given a Wireless Things OpenPi device. This is based on the Raspberry Pi Compute Module and hence is a different beast to put software on compared to the regular Raspberry Pi models. The big difference here is that there is […]

Using Resin.io with Node-RED

I’ve been involved with Oxford Flood Network which is currently one of the showcase projects in the recently opened Digital Catapult Centre. For about a year now I’ve been using Node-RED, including developing the Twilio node for sending SMS. Node-RED is being used on the Raspberry Pi as a gateway between the sensor nodes and […]

Oxford Flood Network Sensor build

These are the first draft of the detailed build instructions for the V3 Oxford Flood Network river level sensor. The sensor uses an ultrasonic transceiver measure the distance from the sensor to the water. The changes in the water level are registered as changes in the distance measured. This can then be used to calculate […]

What to do with surplus dev boards

I’ve been using Arduino boards for a few years now and it re-kindled my interest in microcontroller systems after having worked in the field quite a few years ago. Since then I’ve also used various Arduino compatible boards, shields and d-i-y boards, I’ve created libraries, published code and generally had a lot of fun with […]

Remote controlled LED Kitchen lights

Introduction

Over the Christmas and New year holiday I’ve been doing a little kitchen refurbishment. This included the usual repaint and replacement of cabinet doors and handles. As an extra I decided to add some additional lighting above the cabinets to illuminate the ceiling. This is achieved using a more than 5m of 12V RGB […]
