    As the European Parliament votes on the Withdrawal Agreement, history will record the language of friendship prevailing there, in sharp contrast to our own MPs' and MEPs' inane talk of bogus liberation from some phantom oppressor, they themselves created. A fitting punchline.

    Just watched the footage of Farage and his band of union jack-waving pricks. It’s so deeply embarrassing, so disrespectful, so undignified, shameful and insulting not only to the EU but to those of us in the UK they have represented. Good riddance to them.

    The Soyuz spacecraft used a digital clock on the control panel. Surprisingly complex, the clock had over 100 ICs and a switching power supply crammed inside. I open the clock and explain what all these chips do. Details:

    The Soyuz spacecraft clock is a gray box with two rows of LED digits on the front, as well as switches and buttons.
    The clock opened up. The circuit boards are fanned out, showing the circuitry inside the clock.
    The switching power supply board has transistors, inductors, ICs, and other components.
    One of the digital logic boards. It has rows of surface-mounted flat-pack integrated circuits.

    Nice tiger chip art on Dallas Semiconductor wafer from 1987. Interesting NPN/PNP transistor test circuit as well as feature widths from 50 μm down to 1 μm. "I'd rather be modeling." The 9256 and 2256 part numbers don't match products; maybe this was a development wafer?

    Test circuitry on an integrated circuit wafer. Square structures for NPN transistors and circular structures for planar PNP transistors.
    Text on a silicon chip wafer: "I'd rather be modeling" (C)(M) Dallas Semiconductor 1987
    Test circuitry has lines varying from very wide 50 μm line to very narrow spiraled 1μm line.

    The Dallas Semiconductor 2435 is a three-pin chip to identify a battery and sense its temperature over 1-wire interface. The die is surprisingly complex and has some interesting chip art: a padlock labeled "Security Products", a DIP with thermometer, and a battery(?) with dog tag

    Honestly this board is packed with sensors, runs CircuitPython, faster CPU, tensorflow lite, mp3 decoding, 1.3" LCD screen, Bluetooth, Sensors: colour, luxe, proximity, magentometer, 6 DOF motion sensor, pressure and temp, humidity, microphone...and it is the size of a micro:bit!

    A solid ring will be caught by a loop of chain if it tumbles during its fall. By Newton's Third law, when the ring twists into and hits the chain, the impact transfers momentum to the end of the chain, which rises up and over the ring
