   The GPT Golden Goose consists of 2 parts: 1. Smart people with the knowledge and motivation to build the Goose. 2. The compute required to create Eggs. MSFT now has both. I don't see how any regulatory framework could have prevented th

   There is a lot of 'it depends' on the efficiency of solar in winter. Solar is actually more efficient in winter, but depending on your latitude you get less hours of sun, and a lower angle of incidence. Heat pump up-front cost are

   Everyone that has > 5KWp solar and a heatpump is laughing right now.

   Agreed. Maybe some are not as sensitive to this, but it is a major energy suck for me. A little post-processing on noise and compression would come a long way. This recording is as raw as the Ramsey meme.

   I went to several demoscene parties in the late 90's. It was the most inclusive crowd I've ever been part of. People from all countries, walks of life and genders. There was a place for any kind of freak. It really learned me to a

   I used Home Assistant to create a play about Judy Resnik, an amazing engineer that died on board of Space Shuttle Challenger.

   Running your own Zigbee network is not that hard. I am a Home Assistant fanboy, but you can just use it to bridge your Zigbee network to Homekit without having to know how it works.

   I love home assistant, but I wonder for whom this is. I presume this is for non-tech people, but how are they going to discover it? Without brick and mortar distribution, this is not going to fly imo.

    Arduino is in the lifecycle stage where they need to accelerate extraction. Unfortunate for some maybe, but as a hobbyist, the ESP hardware and software offerings are miles ahead anyway.

    Thanks! I wish I learnt more control theory in my education, this is helpfull.

    Thanks, I never really understood feed-forward well, but modeling the thermal mass makes a lot of sense for keeping the terms in check. (As I understood it in Betaflight, it overrides the PID controller and mixes setpoints directly into the

    Yes, you're correct. I think you never see them in practice since MCU's are cheaper, but it is totally doable.

    Actually the article is wrong about this. "...compared to traditional thermostats found in many older espresso machine steam boilers". Older espresso machines mostly use a "pressostat": an adjustable pressurized diaphrag

    I'm familiar with algorithmic and manual tuning, and the more latency the system has, the more time consuming and harder it is to get right. Genuinely curious how a block diagram would help?

    PID controllers require more tuning, which becomes harder with more latency in the system. They are more susceptible to integral windup: https://en.wikipedia.org/wiki/Integral_windup They require an MCU, whereas a bang

    When your espresso machine has some thermal mass (eg E61 group head), then a simple bang-bang controller performs just as well as a PID. After tweaking PID controllers in drones, HVAC systems and my espresso machine, my experience is that P

    I really, really don't understand why these simple-ass microcontrollers are running proprietary software instead of something open source like ESPHome or Tasmota. There is no added value in the proprietary software running on an MCU wi

    I love the look of 7-segment displays. If you want one that is WiFi controlled via an ESP32, check out my blog post: https://willem.vooijs.eu/posts/cute-astronaut3/

    I wonder who this is for. It could be a great homelab server, but only 16GB of mem ruins that idea.

    Very true, this can be a nuisance. Most of the times I plop it in my backpack (which I always carry). When at a bar or restaurant this is fine, but walking with it is certainly not ideal.

    I have one with a detachable battery. Apart from the charging convenience this brings, it also makes the bike way less attractive to steal.

    I made my own electric bike by purchasing a brand new Stevens City Flyer and mounting a TongSheng Tsdz2 Mid Drive motor to it. It is light, fast, and really easy to maintain. I've been riding it daily for the past 3 years and it has br

    All of those are absolutely real. There is a lack of economics and a surplus of optics in the game for all players.

    Europe’s lack of proper launch locations inhibits startups from attracting talent. So ESA sticks with Airbus since that’s the only option.
