Detecting Sarcasm with Deep Convolutional Neural Networks

An Austrian firm is building an electric firetruck! Another exceptionally loud diesel truck that spews cancer causing pollution can now be a much quieter electric truck.

Electric powered bicycles are interesting. Both electric and small engines have been used on bicycles for more than a century.

This kit looks interesting:

48V 1000W 26" Electronic Bike Conversion Kit for Front Wheel Motor ...

at a cost of ~$160 USD.  I wonder if it would be strong enough for a tricycle with a front and rear basket loaded with groceries, and/or other items.

The area I live in isn't bicycle (or foot traffic) friendly. The roads are too narrow and the traffic is too dense. There are a lot of tourists who don't know the roads and have visited wineries.

England has made some neat airplanes.  The Harrier vertical take of and landing plane was way ahead of it's time.  I think the Mosquito used during WWII was inovative.

Har har, har

Swarming gizmos may be more problematic.

Might be out of line, but Stephens post  "Hey Budd, Cand you Give Me a Hiand?

Reminded me of the following By Yip  Harburg - the songwriter for the Wizazard of Oz. - Who was black listed.

Doesn't mean much.

Davy,

What do you mean by O/P? Operational Parameters?

As you know transformers increase, or decrease AC voltage. Rectifiers convert AC to DC.

Perhaps it's a good idea to make the connectors different so people don't mistakenly plug their device into the wrong power supply. If they were interchangable it wouldn't matter.

It shouldn't be difficult to make a common power supply so different power supplies work from the same source to supply a variety of different devices.  USB seems to have helped for small devices.

Other battery supplied devices still have 'proprietary' voltages and adapters such that they aren't interchangable.

This is where IEEE  and other engineering standards may be helpful.

Chris 
What are the transformers used for? 

What are their O/P's AC or DC? 
Are they bare trannies?
