Dunno. TI has a useful page though: https://www.ti.com/solution/hearing-aid That page basically says use an all in one "MSP430F5510" MPU with "CC2640R2F" Bluetooth.

Metal MILO [1] tins are pretty good. The tight fitting lid provides a continuous RF seal and being tin-plated you can solder though connectors in place, providing good ground continuity. [1] https://en.wikipedia.org/wiki&#

Fun fact: The original VW beetle could do this for half an hour or so [1]. There was a (1960s?) article in "Modern Motor", whereby someone tested it and found that there was at least some control, as the tyres provided enough pad

I'm not thinking that battery replacement would be seen as a way of recharging or be done on the road. It would be infrequently done, when a change in capacity/technology is required or the module is worn out. The interface speci

Not the entire battery. Something in between an individual cell and an entire battery. Small enough to provide practical manual handling and some granularity in total capacity. Big enough that a reasonable number of them add up to a full

Why don't electric cars use replaceable battery modules with a standard form factor? Advantages would include: 1) It allows the battery to be easily replaced as the car gets older. 2) With a suitable generic form factor, it would allo

And here's a video of them milking the snakes: https://www.youtube.com/watch?v=8JDwMDlcBhE It's nuts. Hats off to Zac the snake handler. Stats from the video: 1 vial of antivenom requires 20 milkings. Worst case

If you're in Sydney, Australia, head an hour north to visit the Australian Reptile Park. It's a small zoo that additionally specialises in snakes and spiders that can kill you. It is the sole source of the venom that gets used t

I've been happy with the half dozen Kobos in my house. Weirdly, about half of them have developed a problem after about 5-7 years, whereby they intermittently stop charging. Replacing the battery doesn't seem to fix it. Might be

Same reason we use binary computers? The greater noise margin on each bit typically offsets the requirement to have more/smaller/shorter bits compared to a multilevel signal.

Is there a Moore's Law for qbits, meaning do they increase exponentially with time? If so, we are halfway there, from when we stated with 1 qbit. log(133)/log(10000) is approximately 0.5.

Also keep in mind that wall studs are usually a standard distance apart (600mm or 450mm in Australia), so such pictures have an "inbuilt" tape measure.

In Australia it can cost $0, including home visits after hours. The actual cost is between 2% and 3.5% of your taxable income. A person on the average Australian salary of A$90,000/year would pay $A1800/year. For that you get d

It's deeper than that. You can't have advanced communications without gleaning the information needed to form a 3D image. To get maximum data throughput, modern communications systems measure how the channel (ie. environment) cha
