To USB or Not to USB


USB on Bikes, In Ice, and some Ice Jokes

USB on Bikes

So I went to buy new lights for my bicycle. I turns out all the new rechargeable lights use USB. In fact, they use the original mini-B connector. This is the larger, more sturdy connector. If you have a Samsung phone or android phone, it likely uses the micro-B connector which is thinner.

Anyways, I asked the bike tech, and he said,  “You just bring it inside the house and charge it like your phone”   Since the battery life is about 20 hours or more, this means really you only need to bring it in for charging depending on how much you actually bike at night. So it’s not bad.  The best thing, is that that lights are super bright compared to the lights you can support with an LED and AA batteries.  (I probably still prefer to use rechargeable, removable AAA or AA batteries).  I bought a tail light and head light, and installed them on my son’s bike.  Then I followed him and could much more easily see him from over ½ mile away compared to his old LED + Button battery lights.

I’m quite happy with them. My only concern is charging them so they are always ready to use at night.

This also means I need yet another multiport USB charger to charge more USB devices.

Everyday USB

I’m writing mostly about USB everyday. We are working on so many projects in Automotive, Consumer, IoT, and other areas. I can’t talk about them or even point in the right direction.

Also, it’s surprising hard to blog every week about something new and relevant to you. So I’ll just blog about something neat that I learned or used, or bought, or experienced, so something that someone threw at me in the hallway.



And if you want Crystal Clear Ice Cubes, you can buy this this $120 Ice Sphere mold and cooler at

And you can go to Wikihow and use your household items to do the same thing.

There’s no USB anywhere in that Ice making thing.

I just thought this was a great idea.  The science is simply, you freeze your water from top to bottom or bottom to top (not uniformly from all sides at once).  By freezing unidirectionally, (Like a USB Transmit path for USB 3.0), the air bubbles can escape.

If you have bunch of extra cash and the space for this Styrofoam cooler and mold, I say you should buy it immediately.  At least buy it in the US before the tariffs go up on all imports.  You’ll need to make clear ice to go with all the cheap vodka we will be getting from the (New!) Soviet Union (Now with extra Crimea!)


And here’s what I’m listening to this week, all week, the week of January 22-27 because it makes me happy.  I’ve almost met this singer. He’s as genuinely happy and cheerful as he is in these videos.
