As a substitute of rooting an Android cellphone, Brian Benchoff designed a $15 transportable pc. Its description is one which solely Benchoff might write. He describes that it’s gradual, there is no such thing as a GUI, and it doesn’t value $15 (to construct in a amount of 1). However, it does slot in your pocket, runs Linux, and may play a model of Doom!
The $15 pc options an Allwinner F1C100s system-on a chip (SoC) working at 533 MHz with 32 megabytes RAM. A possible improve is a pin-compatible chip with twice the RAM (F1C200s.) Moreover, this SoC incorporates a single USB PHY, which Benchoff related to a USB-A port.
That USB connector and some GPIO pins allow loads of connectivity choices. For instance, you could possibly add a WiFi adapter and use the membrane-style keyboard to carry out command-line actions like pinging a server. Or join an I2C-based sensor to the header pins and information log to the onboard microSD card.

At the moment, the $15 pc runs Buildroot, a Linux model that targets small embedded programs just like the F1C100s SoC. Because the 2.3″ IPS TFT display screen isn’t touch-capable, Benchoff has no plans to incorporate a GUI.
Not like most gadgets we see at present, Benchoff has no Lithium or LiPo battery assist plans. As a substitute, the battery of alternative for this pc is AAA-sized NiMH batteries. This older expertise doesn’t present the identical power density as a Lithium battery, however they’re very low-cost and have fewer delivery restrictions.
So is $15 the precise value, and may you get one? Type of and possibly. To attain a $15 value level, you should buy the parts in giant portions. (And, presently, they’re obtainable!) To get one, Benchoff says he plans to promote the gadget ultimately. Regardless the design will probably be open. For extra info, go to this web page.
After lacking in motion on the final earnings name, Elon Musk was again to offer his tackle Tesla’s This autumn name yesterday. As all the time, he added fairly a little bit of coloration (and humor) to his evaluation. Tesla’s “technoking” had rather a lot to be pleased with — particularly in gentle of one other loopy 12 months for Crew Earth.
The auto business, as many are conscious, was stricken by a important chip scarcity. In line with Musk, “final 12 months was chip hell,” it was nothing wanting “chip drama central.” Even so, Tesla was “capable of develop nearly 90% whereas at the least nearly each different producer contracted final 12 months.”
So will the chip scarcity lastly abate? Musk appears to assume so, and made a fairly amusing analogy. He defined, “I feel there’s some extent of the bathroom paper downside as properly, the place, you recognize, there was a bathroom paper scarcity throughout COVID, and like, clearly, it wasn’t actually, definitely, an amazing enhanced want for ass wiping.”
He continues, “It’s simply folks panicked … and obtained each paper you possibly can probably wipe your ass with mainly. … So [it was] an odd selection for folks to panic about … if [the] finish of the world is coming, having bathroom paper is the least of your issues.”
So, very like the bathroom paper fiasco within the shopper items sector, within the auto business, “I feel we noticed simply loads of firms over-order chips … [but] we’re seeing alleviation.” As well as, “It’s not a long-term factor [anyhow] as a result of there’s going to be — there’s a large amount of chip fabs being constructed, which is nice.”
Tesla’s CFO Zach Kirkhorn sees a vibrant future forward. He famous, “As we glance ahead, we anticipate 2022 to be one other important and thrilling 12 months for the corporate. We proceed to drive for car quantity development at or above 50%, as Elon talked about, and our plans present that that is truly achievable with simply our Fremont and Shanghai factories.” In the meantime, Giga Austin and Giga Berlin will certainly speed up development this 12 months.
On one other entrance, as soon as full self-driving is achieved, in accordance with Musk, “in the event you run the numbers on robotaxis, it’s type of nutty — it’s nutty good from a monetary standpoint.” He continues, “the automobiles within the fleet primarily changing into self-driving by a software program replace, [which] I feel, would possibly find yourself being the most important enhance in asset worth of any asset class in historical past.”
Musk provides that transitioning from a “dumb” automobile to a robotaxi adjustments it from having, “a utility of maybe 12 hours per week per passenger automobile to perhaps round 50 or 60 hours per week [which is] a 5 instances enhance within the utility of the asset. [Yet] the price didn’t change.”
Musk additionally has excessive hopes for Tesla’s robotic — internally nicknamed, tongue-in-cheek, Optimus Subprime. He believes it might outpace the corporate’s automobile enterprise. In line with Elon, “The muse of the economic system is labor. Capital tools is distilled labor. So what occurs in the event you don’t even have a labor scarcity? I’m undecided what an economic system even means at that time. That’s what Optimus is about, so [it’s] crucial.”
In the long run, there’s lots to be enthusiastic about in regard to Tesla’s highway forward. In line with the electrical automobile firm’s This autumn shareholder letter, “Whereas 2021 was a defining 12 months for our firm, we consider we’re simply on the very early levels of our journey. Thanks for being a part of it.”
