Desert plants: a puncturing hazard

A thorn, presumably from a desert plant clipping lying on the road, punctured my inner tube. I found the tiny hole in the tire, but I’d forgotten to include tire levers in the kit I’d brought from home. So, I walked the bike over to a bike shop. I left with a new tube (installed) and these very red tire levers.

Oops, closed Wednesdays

Cycled down to Moorten Botanical Garden. Of course, Wednesday is the one day of the week it’s closed. Continued our bike ride, then got haircuts and did the weekly laundry.

Stalled by joint play in a LEGO mechanical computer

All logic functions can be constructed using AND and NOT logic gates. Modern smartphones contain billions of logic gates. However, the LEGO machine I constructed today only has four AND and four NOT gates to perform binary addition on two single-bit binary numbers. As the signal propagates from the inputs on the left to the outputs on the right, the cumulative effect of joint play leads to unreliable output movements. I need to redesign the machine.

Home for the Holidays

The two of us are cooking up a storm just for ourselves. Santa’s received the “please, no gifts” notice. “I do not want what I haven’t got,” as sung by Bettye Lavette, sums it up. Grateful and contented, I am.

The Future of Work

On my walk home from a medical appointment, I passed food delivery robots idly waiting for their next gig. I opted to dine in and enjoy a lunch I’d ordered through an app, as in-person ordering wasn’t an option. Meanwhile, back at our building, a drone was conducting an exterior inspection, scanning for any maintenance issues.

Monthly Routine

Every four weeks, I undergo testing for a clinical trial. Today’s lineup: lab tests and two full-body scans. The scans show my tumors aren’t growing or spreading, thanks to a promising new therapy. While there’s no cure, we’ve successfully managed this for eight years. I’m grateful.

Bugs, Bills, and Beer

Over a welcome beer at our local, Dwight described his time at the greenhouse battling pests and mold on these grapevines. Meanwhile, I’d been caught in a Catch-22, ping-ponging between a vendor and Amex over fraudulent charges. Eventually, Amex took responsibility and issued a refund, leaving me free to enjoy my beer.

Practical Physics

Downtown had its head in the clouds, it rained pretty much all day: time for LEGO. Instead of relying solely on a solid state gyroscope, I wanted to develop a better intuitive grasp of the physics involved. So, I built a test rig with an actual spinning flywheel. It flew apart, leaving my electronic robot…… Continue reading Practical Physics

Aftermath of a Stormy Night

A storm raged overnight, leaving the odd downed tree to navigate around on our hot and steamy Sunday morning walk. We’re grateful to still have power, knowing many are facing outages today.
