Braces have come to our household, and with them, the need for an electric toothbrush and water flosser. So there’s the Sonicare, three heads, the water flosser with three tips, and a tube of toothpaste. The bathroom counter was getting kind of crowded!

To keep the clutter under control, we printed an organizer on the 3D printer. It’s pretty specific to the Sonicare I and this Zerhunt Cordless Water Flosser, so I won’t put the files on Thingiverse. Just drop me an email if you have a need for the files.

cup holder sleeve (Tesla Model S 2015)

I like bottled water. Yes, I know most of it is just filtered and flavored tap water, but so is Coca Cola. I keep a few bottles of Crystal Geyser in my car and always have an open bottle in the cupholder. I recently got a fresh ride, however, and the cupholders were a bit too generous for the water bottles, which would tilt and spill when I cornered.

mouse rack

No, it’s not a device for making rodents confess.

I use a MacBook Pro as my main computer, and I really love the trackpad. I only use a mouse for gaming and the occasional bit of high-resolution CAD work. I have really limited desk space, though, so the mouse was often unused but in the way.

This dirt-simple print (I don’t think it took me five minutes to design it in FreeCAD) lets me stow the mouse out of the way when I’m not using it.

Source and mesh files for your 3-D printing pleasure are on Thingiverse.

last gas

Back in April I decided to put down a deposit on a Tesla Model 3. When my number came up, though, the price for even a minimally-configured unit was far more than I was willing to pay, so I put off the purchase.

thought innovation

Sometimes, it’s simple things. We’re surrounded by wonders like smart phones and miracle drugs, but sometimes innovation can come entirely from just thinking about a problem differently. If you took an iPhone X 30 years into the past, it wouldn’t do much. Oh, it might be a shiny curiosity, but its function would be limited. Nor would someone in 1988 be able to disassemble it, discover its “secret” and make more of them: the main secret is layer upon layer upon layer of incremental improvements in processor design, chip fabrication, wireless technologies, display mechansims, battery capacities, operating system architecuture… the list goes on and on.

measuring cup rack

In spite of having cleaned up my container lid drawer, I still have problems with drawer clutter. One place I particularly notice is when looking for measuring cups. I like to bake, and so individual-size cups are essential, but I hate pawing through the drawer looking for the right one.

spamassassin update

Most email users are blissfully unaware of the magnitude of the spam problem. Major email providers do a pretty good job of filtering, so you might see little or no spam in your inbox. Even the stuff that gets sent to your “spam folder” is only a tiny fraction of the spam that gets sent to you. That hides the magnitude of a really big problem, and one you pay for even if you don’t realize it.

IPv6If you don’t know what IPv4 and IPv6 are, this post isn’t for you.

If you know, and are wondering how you might implement IPv6, this might be of interest. We handle http/https requests using a white box router running Debian. Until recently, we were IPv4 only, and the router used NAT to connect to an existing subnet with a local IPv4 address space (in the 10.x.x.x range). What makes it odd is that the subnet is also reachable through a different IPv4 address and NAT—it’s ancient history in a network that has been running since the 1990’s.
