  • Terminal Zero: Building the Ultimate Raspberry Pi Zero Computer

    The new edition has no keyboard in favor of a touchscreen interface. The case is custom designed and no only has a huge selection of ports to access but also additional buttons. The unit is completely wireless, using a LiPo battery for power. There's a small speaker inside but you can also use headphones via a 3.5mm jack.

  • Will This Speed up Your Raspberry Pi Browsing by up to 1200%?

    Puffin manages these incredible speeds because the content is rendered remotely on their encrypted cloud servers. A JavaScript engine is used to pre-process and compress web pages before they arrive at your screen. This can be interpreted as a proxy server by some sites, and may affect the content that is available to you.

  • Odroid H2 as ventilator cooling ventilation airmachine

    finally summer and climate change have both reached Europe and had several weeks of 30 C straight…

    without ventilation, anything above 30 is just “too much to think” (so maybe the brain CPU also would need active cooling?)

    of course the user could buy a fan online… or try to use CPU fans to do the job

  • Track your punches with Raspberry Pi
  • Garage Minder

    A Raspberry Pi Zero W is used to open and close the garage door. I did not have a convenient outlet to plug in a power supply for the Pi. So my Pi gets its power from the existing garage opener control wiring for the wall button. Typically, there is 24 volt AC available here, though it may be a lower voltage in older openers. A Buck converter down-regulates this voltage to 5 v DC. A battery allows the Pi to continue when the wall button is momentarily pressed, and the power is shorted out. We need two diodes so that the forward drop (1.4v) stops the 6v battery from continuously discharging into the 5v power supply. The battery is barely used, so it should last for a long time. If an outlet is conveniently available, then a regular 5v micro USB charger can be used.

  • POSIX Compliance Explained: Does It Even Matter In 2020

    Like with the Unix Philosphy, POSIX compliance tends to get simplified far more than it really needs to which sort of makes it seem less important than it really is, so today I thought it would be a good idea to take the time to explain what it is and where it came from and why it was important in the early days of Unix and even now in the days of Linux and various BSD variants.
