Cambridge is our best uni for mechanical engineering but they'd rather push our best young minds to MEMS than the traditional career paths (Lotus, RR etc). Bristol may be doing the latter but I have not bumped into any Mech Eng from Bristol yet.

the Warrior is good for off roading: You may have seen it already in Leigh. The motor is Bafax MaxDrive G330, 48V 12AH battery, range about 35-40 miles. Price: £1,299. A bargain.

how many pins on your motor cable? 3, 6 or 9? if it's 3 or 6, you don't have Halls. If 9 then you need to check the Hall sensors first. After that, you need to check the coils. Set the volt meter to 20V, spin the motor. You should see some voltage between 2 pins of the 3 phase wires / fat pins.

artificial intelligence is not yet intelligence at present but it is progressing fast. We have made good progress in agriculture. Starting with driverless plough tractors a few years ago, now we have robots to pick fruits and plant seedlings. You see the progress to level 4 driverless with very...

your controller may have died.

all the objects are detected as your vehicule sees the landscape and already registered in the driving database. The 10ms is enough to update its database with the changes and comes to its decision. Speed is not the problem, we have plenty of computing power. What we don't have is the artificial...

this image gives an idea the field of vision for a driverless car:

it's about 10 milliseconds at present.

eg you set the microwave on for 2 minutes, if it does not stop, it'll burn your food.

it's going to be effective in the entire European Union's Customs Union, that includes also Turkey, the Channel Islands, IOM, Gilbraltar. I don't know about Norway and Switzerland. It could well be that you can buy Chinese e-bikes cheaper in Switzerland, the country that the EU Commission uses...

cameras and all types of sensors get better all the time.

that's the same situation with all kinds of computer based systems in daily use. If your microwave's clock goes wrong, you may set fire to your house etc. the datastream from an incoming car includes the transponder ID, the reference system eg WGS1984, satellites identification and readings...

where has all our energy gone? to the city. Just like my son with his degrees. He went to Bengladesh to build a wheelchair for Bengladeshi women and got a distinction for his project then went to the city to work for GS.

there is nothing to change. When you ride on a flat road at 15mph, you use about 200W less your own pedaling effort, you will never break the law on electric bikes. When you climb a steep hill, as long as you do not exceed 15mph, you are temporarily allowed to use more than 250W.

he is going to see an awful lot more conversions by this time next year when the huge anti-dumping duty on Chinese e-bikes kicks in by this time next month. Kits are still not hit by anti-dumping.

bike components are high tech, bike assembly is low tech. UK don't have any bike component industry and can't compete on low tech because of the favoured status afforded to developing countries (Vietnam, Cambodia, Bengladesh etc). By this time next month, Chinese e-bikes are going to be hit by a...

that's just a common flaw with crowd funding projects. They usually involve small companies with little experience in software design, same with material selection and the design of the physical lock itself. If you take for example a card key hotel door lock, it's not so easy to break in.

I see a few uses that would pay for driverless car technology at level 4 while waiting for level 5: 1. drive itself to the charging station and come back to the house while you sleep. 2. take over the driving when you are on a motorway so you can have a nap 3. cheap taxi in small villages to...

not much wiring: only the speed sensor cable is getting muddy, in this it's no worse than an average factory made bike, the excess of the battery cable and LCD cable that is normally tucked away inside the frame on a factory bike can be tucked into a little seat post box/bag.

he's made it easy although not strictly enforceable beside the 25km/h. If you have a certificate of conformity, he's unlikely going to book you if it does not say 36V (eg 24V or 48V or anything in between), or the missing CE logo or you have a twist or a thumb throttle.
