Today our local daily evening paper published a story about using the route HS2 to lay a water pipeline.
Full details here
Lets look at some of the numbers.
- HS2 (phase1) Length from Birmingham to London 191.5km
- Diameter of proposed water main 1.98m
- Total cost £1.1billion
- Cost per mile £7million
Thats a big pipe, going a long way. But how much water do you need to fill it. Well
Volume = Pipe Cross section x length
Pipe cross section = 3.07 square metres
Volume = 590,000 Litres
An Olympic swimming pool being 2,500 litres, so about 240 olympic swimming pools.
So while we’ve been waiting for Arduino ethernet to emerge, Project Nanode has been born. Again it brings ethernet functionality to the arduino platform, using a different ethernet chip
Thanks to the good work of Ken Boak (@Monsonite) and drivers from @andrewdlindsay it’s a arduino with ethernet for £22.
I’m hoping to bring a comparison of these two Ethernet enabled arduino offerings to you soon.
We first covered arduino with ethernet back in October, well now it’s finally here.
Priced €40 direct from the Arduino store. Still no details of TFTP bootloading.
Of course, things have moved on since October, and there are now alternatives available, offering arduino with ethernet connectivity.
With more of us making purchases on-line, many of us are now being hit with postage charges that are disproportionate to the actual costs of postage incurred by e-tailors.
Imagine my surprise when having selected 3 items at a new on-line retailer, 2 of which are smaller than a match box, the remaining item being about the size of a pack of cards. I happily supply my details, click thru to select my chosen shipping method and am presented with the following options.
A quick check of Royal Mails site, and £5.67 next-day tracked would post a package 1-1.25Kg in weight to anywhere in the UK, £6.54 0.5Kg Special Delivery by 1pm the next day, £8.95 2-4Kg standard first class postage.
This on-line shop actually listed the weights of the three items as
- 30 grams
- 4.2 grams
- 50 grams
Making a total of 85 grams plus packaging materials. Lets be kind, and say total package weight is 225 grams, and is no bigger than 35cm x 25cm x 20 cm (Large Letter in RM speak) this would imply the following postage charges
- 1st Class £.190
- Signed For £1.86
- Special Delivery Next day 1pm £5.90
- Standard Parcels £4.41
Nothing like the quoted prices, yes I appreciate that there is the actual cost of packaging, and the effort in actually packaging them. But there’s no reason why the ACTUAL postage price can’t be more transparent.
UPDATE: Changing the contents of my basket to the smallest and lightest item just 4.2 grams I now get the following postage.
- 1st Class £3.00
- Next Day Tracked £6.00
- Special Delivery £7.28
I should add that on both occasions my cart value was <£30 so no need for additional insurance on RM’s standard offerings.
