Well, who isn't high if you're using Alpy for Android? 🏔️ Have you tried it yet? I dare you. 🤭😜

My dad gave me this wee barometer/altimeter, made about 1890. Took it out in the Mull hills yesterday - it's as accurate, and smaller, than mobile phone GPS 🤩 🥰 . The longevity and reliability of this 130-year old technology seems inconcievable today. And no spurious precision! 🤓 #InstrumentationDoneRight #Altimeter #Barometer #Mull #Antique

#applewatch series 7 #altimeter isn’t working correctly. It’s showing 955ft #elevation as of yesterday when I know I live at around 520ft. I’ve unpaired/repaired… same issue. Same exact wrong reading in fact..

Any ideas my 7 followers? 🤷‍♂️

Greedy Receivers: FCC Considers Regulating Receivers After Altimeter Showdown

Recently, the media was filled with articles about how turning on 5G transmissions in the C-band could make US planes fall out of the sky. While the matter was ultimately resolved without too much fuss, this conflict may have some long-term consequences, with the FCC looking to potentially address and regulate the root of the problem, as reported by Ars Technica.

At the heart of the whole issue is that while transmitters are regulated in terms of their power and which part of the spectrum they broadcast on, receivers are much less regulated. This means that in the case of the altimeters in airplanes for example, which use the 4.2 GHz - 4.4 GHz spectrum, some of their receivers may be sensitive to a part of the 5G C-band (3.7 GHz -3.98 GHz), despite the standard 200 MHz guard band (upped to 400 MHz in the US) between said C-band and the spectrum used by altimeters.

What the FCC is currently doing is to solicit ways in which it could regulate the performance and standards for receivers. This would then presumably not just pertain to 5G and altimeters, but also to other receivers outside of avionics. Since the FCC already did something similar back in 2003 with an inquiry, but closed it back in 2007 without any action taken, it remains to be seen whether this time will be different. One solid reason would be the wasted spectrum: a 400 MHz guard band is a very large chunk.

Thanks to [Chris Muncy] for the tip.

Battery-less Bike Computer Gets Power and Data from the Wheels

Bicycle generator technology has advanced far beyond the bottle dynamos of years past, which as often as not would introduce enough drag when engaged to stall the bike. Granted, it's not as much of a current draw as a big old incandescent headlight, but this wheel-powered cyclocomputer is a great example of harvesting both power and data from the rotation of a bike's wheel.

While there are plenty of cyclocomputers available commercially, [Lukas] was looking for some specific features. His main goal was something usable at night, which means a backlit display, ruling out the usually coin-cell power sources. His bike's hub dynamo offered interesting possibilities -- not only does it provide AC power, but its output frequency is proportional to the bike's speed. This allows him to derive speed, distance, RPM, time-in-motion, and other parameters to display on the 1×8 character LCD display. There's some clever circuitry needed to condition the output of the hub dynamo, and a 1.5 farad supercapacitor keeps the unit powered for about four days when the bike isn't in motion.

As for measuring the frequency of the dynamo's output, [Lukas] simply used a digital input on the MSP430 microcontroller, with a little signal conditioning of course. He also added a barometer chip for altitude data, plus an ambient light sensor to control the LCD backlight. Everything lives in a clever 3D-printed case with a minimalist but thoughtful design that docks and undocks from the bike easily; [Lukas] assures us that a waterproof version of the case is in the works.

We really appreciate the elegance of this design, and the way it uses the data that's embedded in the power supply. While [Lukas] appears to have used a commercially available generator, we've seen other examples of home-brew hub dynamos before -- even one that offers regenerative braking.
