   So 260 instead of 1500 model 3's. Bootstrapping has a lot of uncertainties so that's not very unlikely even. What's stood out to me was this, > In total, we expect to deliver about 100,000 Model S and X vehicles in 2017, w

   A thing I hadn't really thought of was that perhaps the main goal from Uber wasn't to explicitly gain access to Waymo secrets (as in documents etc) but simply how to recruit the whole self-driving cars team from Waymo. Uber trying

   No problem, I'm happy to share what I've learned! Yeah, connecting to the web can be stressful to a small device, but it's very feasible. A basic OS that handles timers, a communication stack, a way to abstract tasks and comm

   Also, > THEC64® Mini will hit the shops in early 2018 with a suggested retail price of £69.99/$69.99/€79.99. And the controller looks similar to a Tac 2, which is a win in my book :).

   In style with NES Classic and SNES Classic, now comes the C64 in similar style - small package with a couple of controllers and HDMI. Keyboard support to write Basic. A handful of built-in games. I guess it's basically the same inside

   The steady-state static draw is the current consumption that is always there even if nothing is going on. Everything else that happens is added on top of it, so to speak. When the microcontroller is at sleep it will consume a certain amount

   You need a gateway more or less since the devices don't use the same physical means of communication as the other ones on the network. The mesh network devices in this post use a 802.15.4-compatible radio, which doesn't work with

    Yes, a transmit-only approach would be the most power-saving approach here, but you'd lose the ability to adjust configuration on-the-fly, and firmware updates over the air (FOTA), among other things. LoRa has excellent long-range prop

    Thanks! You are correct, the li-poly I've looked at specify basically the same operating temperatures, discharge: -20 to +60 deg C charge: 0 to +40 deg C Exactly, the energy density is much less with lead acid, and they also have poor

    Such a solar panel is quite large/powerful and you can drive quite a lot on that, depending on how and where you deploy it. One of the most important factors on how to make it live longer is to limit the steady-state static draw (ie en

    Even if it operates in the unlicensed freq. bands, ie ISM bands, there are still limitations to how much you may interfere with others, expressed in eg duty cycle requirements (ie not sending too long at a time) and energy levels (ie not se

    Aha, I always figured that was primarily due to the risk of mold and unwanted organic events in the dust compartment. It's interesting, air and cooling. I read that a problem that might occur if you are changing to wider tires on the c

    Dyson might find a niche as a motor vendor to others that build the rest of the car, instead of actually building cars. I can see that as a better thing.

    I wonder how much of their knowledge of motors and batteries are usable in cars though. The power draw and load characteristics must be very, very different and I don't think it simply scales up. A fan or vacuum motor is basically ramp

    Thanks for the link, great overview. I think this ominous line rings particularly dark and gruesome, "Cassini reconfigures from an orbiter to an atmospheric probe".

    For us on the hither side of the pond, "7:55 eastern time" means 13:55 Stockholm time. Since the US is so vast in all directions, "your" time references always confuse me. 0 days, 21 hours, 42 minutes, and 10 seconds. Th

    I really like and appreciate the notion that a project could/should state what the assumptions are, where applicable. And, perhaps point out weak spots that could be important to users. If nothing else, it sets the expectations right.
