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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
I’ve been using GitHub for a couple of years now for distributing code, but for about the past 6 months I’ve started using Bitbucket, initially in a collaboration for http://max1284.homelabs.org.uk/. Both services offer similar features but at present neither ticks all the right boxes. Below is my comparison of the two.
Both services offer the [...]
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 [...]
Important Note: I have now stopped development work on the EtherShield library However, this is not the end for Arduino and ENC28J60 libraries. The excellent EtherCard library from Jeelabs. I have decided this is the library I am to use in my examples and future ENC28J60 developments.
As the two librariers are based on the [...]
I’ve been playing around with a couple of Nanode boards for a while now after having an early beta version. Check out the link for full details and specs. The latest version has a few options and I am using one in standard form to connect my CurrentCost electricity monitor to my local lan to [...]
