Tesla Model 3 Torn Down, Hacked and Set On a Dynamometer, Exposing Unusual Tech Details (electrek.co)
Rei writes: With an estimated 8,670 Model 3s delivered, a race is on as competitors and owners work to figure out its limits and explore the tech behind it. Many-time Tesla teardown expert "Ingineerix" has posted a series of videos and discussed his findings on Reddit. Among them: what appears to be the industry's first switched reluctance motor, a massive "smuggling compartment" allocated for a future front-wheel motor, no physical fuses (all solid-state), significant wiring harness length reductions via the use of multiple body controllers, a swappable crash energy absorption system, a liquid-cooled compute unit, and redundant controllers for all safety-related systems. He followed up by posting a screenshot of the car tricked into "factory mode" to reveal its internal specs, including a 1200A max discharge current, 370kW max discharge power, and a 76 kWh pack with 72,5kWh usable. Meanwhile, Munro and Associates tore down a Model 3 for an undisclosed, "not Tesla" client, releasing a video criticizing its build quality and for difficulty in accessing the HV cables in the event of an accident (Munroe's claims were dismissed by Ingineerix). Meanwhile, engineers from German automakers were extremely impressed by what they found during their teardown -- particularly the power electronics system, which they described as "compact, expandable, fully integrated, modular, easily accessible, well-protected, reasonably priced and astonishingly clever in many details." Other owners have been putting their cars on dynamometers to measure their power. Drag Times suffered some skid and measured a conflicting 281 / 327.6 hp with 552 lb-ft torque. Contrarily, Tesla Repair Channel found consistent readings around 250hp when starting from 30mph, but consistently around 390 hp when starting from 10mph. The reason for the discrepancy is not yet clear. -
Eyes on Karamba
An anonymous reader writes "dot.kde.org posted an interview with Hans Karlsson, the author of the now pretty popular KDE clone of Samurize, Karamba, which is responsible for the recent craze at kdelook.org. An interesting interview well worth a read which shows that even today most open source programs still start as tiny hobby projects after all." -
Bluetooth, GSM, and Gameboy
brnsurgon1 writes ""The aim of the project was to investigate mobile gaming over GSM- and Bluetooth- networks, by developing a concept prototype, connecting a Gameboy to a mobile phone over Bluetooth. The results show that it is possible to connect two Gameboy Color over a GSM network by connecting to the phone using the Bluetooth plugin we developed for the Gameboy."" A couple other have submitted this story - it looks interesting. But, heck, I'm still trying to finish Golden Sun on my GBA.
