A Pocket-Sized Terminal for Mobile Python Hacking

Inspired by the good old days when your computer would boot directly into BASIC, [Le Roux Bodenstein] has created a handheld device he calls “DumbDumb” that can drop you into a MicroPython environment at a moment’s notice. If that doesn’t interest you, think of it this way: it’s a (relatively) VT100 compatible serial terminal with a physical keyboard that can fit in your pocket.

Being essentially just a dumb terminal (hence the name), there’s actually not a lot of hardware on the board. Beyond the 320×240 NewHaven 2.4 inch LCD, there’s just an STM32G071R8 microcontroller and a handful of passives. Plus the 57 tactile buttons that make up the keyboard, of course.

The MicroPython part comes in thanks to the spot on the back of the board that accepts an Adafruit Feather Wing. In this case, it’s the HUZZAH32 with an ESP32 on board, but it could work with other variants as well. With the wide array of Feather boards available, this terminal could actually be used for an array of applications.

So even if fiddling around with MicroPython isn’t your idea of a good time, there’s almost certainly some interesting software you could come up with for a tiny network-attached terminal like this. For example, it might be just what you need to start working on that LoRa pager system.

Uber claims top spot in Indian ride-hailing market

Uber facilitated 14 million rides a week in India last year, the American ride-hailing firm said as it claimed the tentpole position in the key overseas market. In a report  (PDF) published on the sidelines of its quarterly earnings Thursday afternoon , Uber said that it commanded over 50% of the ride-hailing market in India — among some other regions — and was the category leader. The publicly listed company cited its internal estimations for the claim, it said. In comparison, Uber handled 11 million rides a week in India in 2018, a spokesperson told TechCrunch. The revelation is especially interesting, since both Uber and its chief local rival Ola have tended to avoid talks about the number of rides they serve in India. In a 2018 blog post , Ola revealed that its platform “moves over two million people every day.” A spokesperson for the Indian startup, which like Uber counts SoftBank as an investor, declined to reveal the new figures, but issued a statement in which it ...
