  • Budgerigars (small parrots).

    They’re active, smart, and social. They fly.

    So I made them a flight cage that takes up most of the room they’re in. I’d prefer a full walk-in aviary, but don’t have room in my apartment.

    Cleaning isn’t bad, I just shop-vac out the litter tray & refill it with a 20lb bag of corn cob bits. Fresh food in the mornings, take it out & replace with pellets around noon. Clean water daily. Millet treats when I let them out (about an hour per day to interact with them).

    Feathers get everywhere when they molt. And feather dust. Their room has its own HEPA filter.

    Vet appointments are more expensive for exotics than cats & dogs. There are fewer exotic vets, and I always go to a board certified avian vet. Boarding when I go on vacation is also more expensive (about $50/day), especially since they’re flighted.

    They’re not anywhere near as loud or destructive as larger parrots, but that doesn’t mean they’re quiet. Just means they might not damage your hearing from the next room. They wake up with the dawn, and let you know about it.

    They’re extremely sensitive to airborne toxins (avian respiration is rather different from mammalian). That means absolutely no teflon cookware use, no air fresheners, etc.









  • Also bleeding-edge processes mean smaller, thinner gates. That’s what gives them the fast switching speeds, but it reduces the max allowable voltage. For parts that need to handle more than 1.8V or so a modern 5nm process will just end up using bigger gates than the process is optimized for. May as well go with an older process (bigger minimum gate size) that’s better suited to switching the voltage needed. For Bosch (automotive parts, power tools, etc) they’re making a lot of parts with really big output transistors (switching 14V, 48V, etc) and not super high-performance processors.

    The big disadvantage with particularly old processes is that they used smaller wafers. So fewer chips per wafer processed, meaning lower overall yields and higher price/chip. The switch from 200mm wafers to 300mm in 1999 meant the wafer area increased by a factor of 2.25! 300mm wafers also required fully-automated factories due to the weight of a wafer carrier (a front opening wafer pod, or FOUP, is 7-9kg when loaded with 25 wafers), which save on labor costs. So processes older than 1999 (around the 180nm node) are sometimes not worth it even for power electronics.
