Update 07 July: crowd funding period has ended, with over half a million dollars raised, but you can still pre-order on Indiegogo – see below.

● Short enough to fit into your backpack – 7 fret version is just 18 inches (45.7 cm) long – but if you’d prefer, the 12 fret version is 24.5 inches (66.23 cm)


● Length is OK, but where’s the body? – add on body available for both models



● Teaches you to play with software for iOS & the Chrome browser


● Never needs tuning – overcoming a significant barrier for many beginners – & very unlikely to ever need strings replaced


● Already a player? ‘Jamstik 12 is designed as a no-compromise MIDI controller that simply, “works” with the studios & production software producer-guitarists are used to. Finally, a way for guitarists to express themselves the way keyboardists & drummers have been able to for years.’

Elon Musk: Tesla compact car, battery energy density, Elon time & improvements in the Model S

At the Q&A following the Tesla Shareholders’ Meeting on Tuesday, some interesting questions were raised & some even more interesting answers were forthcoming. See the video below, or more briefly:

Will Tesla build a compact car – around the 00:30 mark – “... compact car in less than 5 years …”

Autopilot remains a work in progress, with no promise of a major improvement any time soon – 00:45

Steering wheel – 13:16 – “Model Y ... will not have any leather in it … in the steering wheel, even if it does have a steering wheel.”

Battery energy density – 13:45 – “Twice as much is tricky, but we can certainly see a path to about a 30% improvement, maybe a 40% improvement in energy in the same size battery pack, that’s technology we are confident does work & needs to be scaled up & made very reliable … 2-3 years to get to about a 30% improvement in volumetric energy density … 6 to 8 years to get to a doubling … highly dependant on … lithium anode …”

Tesla time estimates – “Elon time” – 23:37 – “I think I do have like an issue with time [laughter & clapping] … my brother used to, like when we were catching a bus to school, he would lie to me about the time … & then we’d actually be able to catch the bus.”

Will Tesla make a motorcycle – 25:30 – “… used to ride motorcycles when I was a kid … dirt biking … had a road bike until I was 17 & was almost killed by a truck, so we’re not gonna do motorcycles.”

Improvements in Model S1 – 29:45 – “One thing we haven’t been good at educating people on is that the Model S ... has improved very dramatically from 2012 … arguably on version 3 or 4 of the Model S right now ... really a gigantic improvement … I really encourage anyone who’s got an early Model S to test drive the current version. I think you’ll be blown away by how much it has improved.”

1 It’s easy to forget that the Model S has been in production since 2012 – partly because the original aesthetics were so good (after 6 years, it still looks as fresh as tomorrow). To the casual observer, the only change has been the revised nose in 2016.

For anyone following the Tesla story, there have been many improvements, including:

Supercharger network – wasn't even promised when the first owner took delivery – not a change to the car per se, but as important to the long-range driving experience as petrol stations (gas stations, service stations – what ever they are called where you live) are to a fossil car

● Greatest available battery capacity has jumped from 85 kWh to 90 & most recently, 100 kWh

● 4 wheel drive

● Software, including Autopilot has seen many upgrades,2 which has necessitated;

● Computer upgrades – more than 40 times increase in computing power in October 20163 & a further upgrade in February 20184

Autopilot hardware upgrade – increase in the number of cameras (8 cameras provide 360° vision) & other sensors3

● Redesigned seats

● Adjustable air suspension
