It was a fine sunny day, I decided to try doing the 7 km round trip to the dermatology clinic on the mobility scooter. I turned around just after getting halfway there, the battery pack was probably not going to last. I distinctly remember connecting it to the charger after an 8 km outing yesterday but it was unplugged when I started it up today. It seems when I stepped off the thing I'd snagged the cable with my foot and dislodged the connector. I had enough time left to make the appointment time with five minutes to spare by taking the car.

Back in the days of the Roman Empire, the famous Emperor Nero instituted a new game. The players would take those little disks you set your glass on in order to protect the furniture, and see who could get the most distance rolling them across the floor.

They were the first roller coasters. Back in those days, the disks were made of iron, and they would bet on whose disk would roll the farthest.

They called them ferrous wheels.

I recently bought a pretty serious self-propelled cordless lawnmower. Because of my back and knee problems I can't use an ordinary push mower. This one has a 17-inch wide cut – other similar models have 19 and 21-inch widths.

About 20 years ago I was working beside a busy suburban arterial around peak hour, with four streams of traffic thundering by, most irritating. I had some cheap wired headphones with a noise reduction circuit so I wore those with NR on but not plugged into anything. I could see the traffic, I could feel the vibrations of its passing but the mind-numbing noise was quite faint.

These are over-the-ear types, a very different experience to tany earbuds.

One of the settings is an effective Transparency mode that allows ambient noise such as voiced through.

Package from Amazon arrived today: Anker Soundcore Space Q45 over-the-ear headphones. The device has a 50-hour battery on board and can connect to an audio source via 3.5mm stereo cable or Bluetooth. It can be paired with two different Bluetooth devices and switch between them by pressing the power button twice quickly. Charging is via USB-C cable and the associated mobile app can be used to set up a personalised sound profile based on emitted sounds, some of which are inaudible to your ears. There are 5 different levels of Active Noise Cancellation as well. They are comfortable to wear and sound really great. Test recordings using the microphone sounds quite good, too. Amazon has a special 25% Prime Members' discount which was nice, too.

I have just taken my own advice and purchased a set of Soundcore Space Q45 over-the-ear headphones from Amazon. Currently they offer a 25% discount for Prime members on this device.

No iPads support wireless charging.

Multi-media USB-C dongle connected to my M1 iPad Air with a Thunderbolt 3 cable from one of the USB-C ports of my Studio Display providing pass-through power to charge the iPad. Then added a USB-A to USB-C cable from the dongle to the iPad’s keyboard case thus charging both the keyboard and the iPad from a single source.
