I took my first prototype to a meeting with Chris the other day and he was impressed with the progress. However there are still a lot of things I have to consider. Firstly, if I used bluetooth or a USB serial connection betwwen my device and a computer it kinda defeats the object of having a device…I might as well write an app. to log the data using the keyboard! Secondly, if I use a GPRS module to combat the first problem, there are issues with cost (£100 for the module + sim card and monthly service charges) and also I have to justify why I am using this device rather than just writing an app. for a java based phone that does essentially the same thing. The point of this device is that is a cheap, open source (to build and software) and most of all simple module to log analogue data. Another point hat was raised is whether to adapt the software I write for the button to work on a mobile phone or PDA and make it available for download alongside the device.
