HOW TO<br />
REPORT IN<br />
WITH iDATA<br />
TRUCK<br />
> STEP 01<br />
Press the button<br />
When Andy loads or unloads,<br />
he presses one of the four<br />
preselected buttons on the iData<br />
Truck so he can let his company<br />
know what he’s up to.<br />
Not only did the buttons tweet his<br />
current status, it emailed his office<br />
then I’ll be able to scan them. If it’s<br />
just scanning to say ‘start of day’,<br />
‘end of day’ or ‘on a break’, it will<br />
tweet that but not email it. If it’s<br />
‘running 30 minutes later’ or ‘box<br />
on’/‘box off’, it will still email it to<br />
the office. So there will be a split of<br />
what data gets sent where.”<br />
What’s next?<br />
Next on the list for Andy is a<br />
camera – Pi-powered, of course<br />
– in a blind spot of his lorry that<br />
will display on his dashboard<br />
and hopefully make it easier to<br />
manoeuvre while reducing the risk<br />
of accidents. He also has further<br />
plans for the iData Truck beyond<br />
his personal use of it.<br />
“I’ve approached the people that<br />
make the software that everybody<br />
uses in the industry and they said<br />
if one of their customers wanted to<br />
use that, then that’s fine, they’d<br />
support it... one person’s been in<br />
touch that can make the hardware,<br />
a box to put it in, the switches in<br />
the panel and the software, should<br />
I want to develop it further.”<br />
So next time you pass a container<br />
lorry on the M3, give it a wave and<br />
you might end up on iData Truck TV.<br />
> STEP 02<br />
Wait for the beep<br />
You need to hold the button down<br />
for half a second: “It kept getting<br />
really hot, so I had to put a delay in<br />
to stop the processor working so<br />
hard from all the loops!”<br />
> STEP 03<br />
Email and tweet sent<br />
An email is sent off to Andy’s<br />
company to let them know of<br />
his status, and a tweet is sent to<br />
the @idatatruck Twitter feed for<br />
everyone to see what he’s up to.<br />
Left The<br />
information on<br />
the iData Truck<br />
stream is always<br />
expanding.<br />
Andy initially<br />
had trouble with<br />
duplicate tweets<br />
until he started<br />
using timestamps<br />
