467 robots are being installed at the Tesla Fremont factory prior to the start of Model 3 production.
Tesla’s Model S is a luxury sporting sedan – the Model 3 is a, “mass market”, car. To appeal to a mass market, the price has to come down – “$35,000 before incentives”,1,2 has been promised repeatedly, for the US market.
Make it smaller, make it out of steel
● Most obviously, reduce cost by decreasing size by 20% compared to the Model S.3
● Extensive use of steel, rather than the more expensive aluminium widely used in the Model S.4
Reduce battery pack cost
An electric motor is simpler & cheaper than an a comparable internal combustion engine – electric cars are more expensive largley because of battery cost. A $35,000 Model 3 will require a substantial reduction in battery pack cost. This will be achieved by:
● Battery costs have been coming down world-wide for some time – including 80% in six years.5
● Price will be driven down further by increased volume – i.e. Gigafactory.6
● Reduce cell count – Tesla has historically used commodity 28650 size lithium ion cells. Individual cells in the Model 3, will be 47% larger in volume, with a similar effect on storage capacity, for negligible increase in cell cost.7
● Each cell stores more power, so fewer are needed for a given pack capacity.7
● Assembling fewer cells to make a pack is faster & cheaper.7
● Smaller battery pack – two options, the larger of which will be, at most, the same size as the smallest currently available in the Model S – “The shorter wheelbase only allows for a 75 kWh pack in Model 3 at current cell/module energy densities.” – Elon Musk, Twitter8,9
Automate the production line
● 467 robots are being installed at the Tesla Fremont factory prior to the start of Model 3 production.10
● Level of automation will increase over time, with no people on the production line itself, “in a few more years”.10
● Increased automation is planned to ultimately yield a 20 times increase in production line speed, further reducing production cost.10
Simplify the production line initially
● Initially, the production line will be simplified by producing only rear wheel drive cars. First 4WD, “probably in 6 to 9 months.”9
Streamline the delivery process
● “We need to deliver three or four times as many cars. But we don’t want to have three or four times as many delivery centers.” – Elon Musk11
● “Less paperwork, less bureaucracy.”11
● Shorten the hand-over to customers: “... get people ready ahead of time with really well-produced instruction videos.”11__________

Hoverboard was a no-show in Back to the Future year.1 We’ve been waiting even longer for the flying car, but Uber has promised them for 2020.
As you’ve no doubt noticed, the problem is that the technology doesn’t exist. Uber’s way around this is something like an X-prize – competitive development of a device to carry out a defined task – in this case, a flying car. And the prize? Access to Uber’s world-wide client-base. Though, at this point only Dallas-Fort Worth & Dubai have indicated an interest.
Uber has signed deals with five companies – if they don’t deliver, an obvious contender would be the Lilium jet electric aircraft.2

Kitty Hawk Flyer
Credit: Kitty Hawk/YouTube/GeekWire
Some details of the, “flying car”, backed by Google co-founder Larry Page, have finally surfaced.
Available specs are thin on the ground:
● weighs 220 lbs (100 kg)
● single passenger
● altitude 15 feet (4.6 metres)
● 8 electric motors drive downward-facing propellers
Kitty Hawk claims that it is possible to learn to pilot the Flyer in minutes, & that it qualifies as an ultra light, so that no licence is required.
Consumer version is promised for the end of 2017.
Trusted Reviews – “Forget self-driving cars, the Kitty Hawk Flyer is officially off the ground”
The Verge – “This is the first footage of Larry Page’s ‘flying car’”
If the name rings a bell, Wright Flyer was the name of the first heavier-than-air machine flown by the Wright Brothers at Kitty Hawk in 1903.1

Although the Lilium aircraft is called, a “jet”, it would be more usual to describe its propulsion as, “ducted fan”.1
Advantages of ducted fans compared to conventional propellers1
● more, shorter blades allow higher speed of rotation & more thrust, without the problems caused by the tips of the blades approaching the speed of sound● reduced noise – especially when driven by an almost-silent electric motor
● surrounding shroud makes ducted fan safer
● occupies less space
In urban environments, where Lilium sees many of it's aircraft operating, these advantages are particularly valuable.
Conventional aircraft generate lift by using relatively few engines to produce thrust (jet &/or propeller) to drive the aircraft forward. Forward speed produces lift due to the motion of the wings through the air.2
A small number of engines is a limitation imposed by internal combustion engines. In an electric aircraft, many small motors can be used.2 Illustrations show the Lilium with 36. Many motors allow lift to be generated at low aircraft speed (even zero) because they can drive air over the wings at a speed independent of the aircraft’s forward motion.
Update – Other advantages of multiple engines include:2
● shorter (front-to-back & side-to-side) wing is lighter & generates less drag
● wings can be optimised for cruise, rather than take off & landing, improving overall efficiency
In an aircraft with few engines, the most difficult & dangerous parts of a flight are taking off & landing, due to the direct dependance of lift on speed. Wings are optimised for these purposes.
Multiple motors, by disconnecting lift & speed, increase safety at take off & landing. Wings can be optimised for cruise, increasing overall efficiency – wings are shorter & narrower & so lighter, with less drag. Check the image above & the video.
Such a configuration will have disastrous glide characteristics. Electric motors are very reliable, & 36 of them provide plenty of redundancy, but battery failure is a problem which does not appear to have been addressed. This is not surprising in a prototype with only one unmanned test flight to its credit. Two solutions which spring to mind are battery redundancy (which may already have been allowed for in the existing battery configuration) or a Cirrus Airframe Parachute System.3
Lilium has its ducted fans pivoted vertically, to direct thrust at a range of angles, including straight down, for vertical take off.
Multiple motors can be run at different speeds to turn the aircraft, eliminating the drag created by a vertical tail.
Drag is further reduced by a lifting body design4 – the body of the aircraft is shaped to produce lift – thus the wings can be smaller & lighter for the same total lift.
Lilium has backing from the European Space Agency.
Engadget – “Lilium's electric personal jet manages a vertical takeoff”
Futurism – “A Real Life, All-Electric Flying Car Just Took Off”
Manufacturer’s web site
1 Just to complicate things, almost all current jets are of the turbofan type, which is a ducted fan, where the fan is driven by a gas turbine – that is to say, a jet engine.
Wikipedia: “Ducted fan”, https://en.wikipedia.org/wiki/Ducted_fan
“The most common ducted fan arrangement used in full-sized aircraft is a turbofan engine, where the power to turn the fan is provided by a gas turbine. Turbofan engines are used on nearly all airliners, fighters, & bombers.”

Bright, shiny new mobile phone – but what to do with the old one? Some people have a drawer full of them. Two of the more popular options are: sell it, or pass it on to a family member or friend. These are obviously good options, depending on your circumstances, but there are others.
Keep it as a spare – that bright, shiny new phone, may suffer a misadventure – drop, or other physical damage, internal failure, loss or theft. In any of these circumstances, another phone to swap the SIM into, or a new SIM, depending on the misadventure, could be very useful.
Second phone – many have abandoned their fixed phone. A second phone with its own account can become a home phone. Some mobile phone providers have pay-as-you-go accounts, with no cost while the phone remains unused. I used such an account with an old phone, for several years, to contact family members at home, at no cost.
Use it as a mobile router – free public WiFi, is not always available when you need it, & is not secure1 – your own mobile data is a more flexible & secure choice. You can use the hotspot function of your mobile phone, or, if your data allocation is insufficient, an additional, data only account. Rather than buying a purpose-built mobile router,2 use your old phone at no cost.
Other possibilities include:
● add it to a multi-camera video shoot
● baby monitor
● video doorbell
● GoPro replacement
● dedicated VR headset
● white noise generator

Pebble 2 smartwatch – last model delivered
Credit: Best Buy
An update to the Pebble app for Android appeared on my phone today. Judging from dates on the comments, it appeared world-wide at the same time. I have no way of verifying this, but it appears that an update for iOS has also been released, or will soon.1
What will the update do for your Pebble?
“WHAT'S NEW” for the update says:2
We’ve updated our Android app to preserve the Pebble smartwatch experience & remove the dependence on cloud services.
The app lets Pebble devices keep working, even if online servers are not accessible for any reason. The login process can be skipped, apps can be side-loaded, & the latest watch firmware (including language packs) can be installed.
Visit developer.pebble.com for full details.
All of which promises to extend the useful life of Pebble watches.
All functions I use continue to work, including:
● notifications: incoming SMS & email
● phone calls
● music control
● step count (with sync to Google Fit)
● weather continues to update – temperature indication retains the inaccuracy which has always prevented me from using it – to be fair, it's no worse than almost every phone app I have tried● watch faces continue to be available for download

Scotty Allen is described by some as a hacker, but it there’s much more than that to him. To quote from his web site:
“I’ve always been an adventurer, maker, & hacker. From riding a $120 bike through Laos & Cambodia, to building & racing land yachts, to planting coral underwater in Borneo, I’ve always sought out the weird, wonderful, & out-of-the-way thing to do.”
“I used to be a software engineer in Silicon Valley, at places like Google & a few other prominent startups. I even started my own. But now I travel the world full time, seeking out the novel & the obscure.”
Some things he found out along the way
● investigated building his own logic board from bare board & chips – “a rabbit hole” – “way over my head” – “not impossible, it’s possible, but very difficult”
● other problem with building a logic board is that the logic board is uniquely paired with the TouchID sensor by Apple – for TouchID to work, logic board & TouchID sensor must be a matched pair – this is a security measure to prevent attackers from gaining unauthorised access by replacing the TouchID sensor
● similar to building a desktop computer, but much, much smaller & thus, much more difficult
● logic board & matched TouchID sensor
● screen – glass + digitiser + LCD + backlight + clear adhesive – had it built by people who had the equipment● back camera
● front camera
● bottom cable assembly, including lightning dock & headphone jack
● lots of tiny screws
● Cost: “I’ve spent over $1000 at this point, but a lot of it was duplicate parts I didn’t end up using & tools I didn’t end up needing. I’d estimate the cost of the actual parts that went into the phone at around $300, maybe a bit more (I wasn’t keeping perfect track).”
● Parts: obtained from the markets of Huaqiangbei Futian, Shenzhen, Guangdong Province, China1
● Time: project took two months, including time outside of China (when no progress was made), working out what was required, & procuring parts

Fuel cells are one third as efficient as lithium ion batteries. In practice, used to drive a car, they yield poor acceleration.1 These problems appear to be fundamental to the physics & chemistry of fuel cells. Or as hydrogen proponent David Wenger, CEO of Wegner Engineering, which developed the hydrogen fuel cell powertrain for the Mercedes F-Cell hatchback put it, “In total, the results are sobering, sadly. That really hurts.”2,3
Elon Musk understands fuel cells too:
Digital Trends – “Elon Musk on hydrogen fuel-cell cars: ‘I just think that they are extremely silly’”, http://www.digitaltrends.com/cars/elon-musk-says-fcvs-are-extremely-silly/
In light of the above, the apparent enthusiasm of some car makers for that technology is puzzling. Mercedes, though is showing signs of having seen the light:
Green Car Reports – “Did Mercedes turn its back on hydrogen fuel-cell vehicles?”, http://www.greencarreports.com/news/1109713_did-mercedes-turn-its-back-on-hydrogen-fuel-cell-vehicles

Tesla Semi truck unveil set for September. Team has done an amazing job. Seriously next level.— Elon Musk (@elonmusk) April 13, 2017
Electric semi has long been in the too hard basket:
● road-freight is low-margin
● making a profit depends on keeping the vehicle moving, which makes long charging times a problem● battery size & weight is less of a barrier in a such a big vehicle
● battery price remains a problem
● energy & maintenance costs will be significantly lower than internal combustion
● battery swapping has been demonstrated,1 but hasn’t taken off for electric cars – perhaps in this application, high utilization in freight centres may make it viable
● short-haul may be the best application for battery-electric prime movers, at least initially

MacBook connected to 29 inch monitor
Credit: The Gadgeteer
Laptop computers have a number of disadvantages compared to desktop equivalents. To a greater or lesser extent, these include:
● smaller screen
● smaller keyboard – keys themselves are not necessarily smaller, or closer together, but numeric keypad – almost never● less powerful processor
● easier to steal
● less bang for the buck
Despite all of these disadvantages, laptops are very popular. This popularity revolves around their portability. Amongst the most portable is Apple's MacBook 12 inch:1,2
● weight similar to a tablet – great choice if portability is at a premium
● 12 inch retina screen
● plenty of power for the tasks most people use a computer for – email, browsing, video, word processing
Below is a review from a new owner who wanted a computer for travel, but is now thinking about selling her MacBook Pro:

Have you noticed
● Easter is on a different weekend each year
● there’s often a full moon just before Easter
● there was a full moon on Tuesday of this week (11 April)● Easter is this weekend?
When is Easter? – simple answer
Easter Sunday is the first Sunday after the first full moon on, or after, 21 March each year. Other days of Easter are positioned around the date of Easter Sunday – Easter Friday (Good Friday etc.) is two days before – Easter Monday the day after, etc.
Applying this rule to 2017
● 12 March was a full moon
● next full moon (i.e. first on, or after, 21 March) was on Tuesday 11 April
● so Easter Sunday is the first Sunday after 11 April – Sunday 16 April 2017
Earliest possible Easter Sunday
“In 1818, as a paschal full moon fell on Saturday March 21 (the Spring Equinox), Easter was the following day – Sunday March 22 – the earliest date possible. It will not fall on this date again until 2285, a span of 467 years.” – Wikepedia1
Latest possible Easter Sunday
“In 1943 a full moon fell on Saturday March 20. As this was before the Equinox the next full moon, which fell on Sunday April 18, determined the date of Easter – the following Sunday, April 25. It will not fall on this date again until 2038, a span of 95 years.” – Wikepedia2

Tesla Model 3 interior as seen at the reveal event – notice centre screen & absence of any instruments in front of the driver. Notice too, the zero in the top left of the centre screen, which is a speed display.
Since the Tesla Model 3 reveal, there has been speculation about the 15" landscape centre screen & the possibility of other instruments in the production vehicle. One popular suggestion has been a head up display (HUD). With the benefit of hindsight, the engineer driving the prototype in my post about the Model 3 reveal was committed to the advantages of the centre screen & eliminating instruments in front of the driver.1
Recently, Elon Musk placed it beyond doubt in a Twitter exchange:
@nickg_uk No— Elon Musk (@elonmusk) March 28, 2017
“You won’t care”? – Elon Musk makes it clear that it doesn’t mean a HUD, but it does imply something in the user interface that will overcome objections to the absence of a speed display in front of the driver.
If, as the owner of a production Model 3, you do care, there are many existing add-on HUDs, including:
