Porsche pen

Image
The rOtring Freeway is ... fine ... but it’s feeling kinda loose and needed replacement in my daily carry kit. Wanted something inexpensive and stumbled across this Porsche Crest Carbon-Look Ballpoint Pen ($25). (Echos of the Porsche Design Tec Flex Steel Ballpoint Pen someone got me after I got my first Porsche, the 968 Cabrio.) Only ... it’s not a ballpoint pen. It’s a roller ball. Which is what I wanted. The included refill writes fine and is about as generic as you can get (it’s got a green “quill” logo with an ®, 2025-04 marking, and reads “International Roller Pen Refill 0.7.” I tried the Pilot, G2 Gel Ink Refill and it  almost  fits, but the tip is recessed a bit into the pen and the diameter is like a hair’s breadth too thick (it got stuck in the tip). It appears this is probably equivalent to a Schmidt 5888M rollerball refill.

The Hailo 10H is out in an RPi bundle

Image
Per Slashdot : Raspberry Pi is launching a new add-on board capable of running generative AI models locally on the Raspberry Pi 5. Announced on Thursday, the $130 AI HAT+ 2 is an upgraded -- and more expensive -- version of the module launched last year, now offering 8GB of RAM and a Hailo 10H chip with 40 TOPS of AI performance. Once connected, the Raspberry Pi 5 will use the AI HAT+ 2 to handle AI-related workloads while leaving the main board's Arm CPU available to complete other tasks. Unlike the previous AI HAT+, which is focused on image-based AI processing, the AI HAT+ 2 comes with onboard RAM and can run small gen AI models like Llama 3.2 and DeepSeek-R1-Distill, along with a series of Qwen models. You can train and fine-tune AI models using the device as well.   $130 is lower than I expected, based on the price for the other Hailo stuff. More on the Hailo H10 . Could probably put together a “play around with” setup for ~$200, a bit less than I ultimately have invested...

Update: Using a Tesla level 2 charger with the Solterra

Image
Solterra charging The cheap BLRENT charger lasted about a year. The cable started to separate from the charging box (I think just the insulation, but it was still unnerving to look at), and then one day I couldn't get the J-1772 plug to disconnect from the car charging port, it had become slightly separated and the push-button wasn’t providing enough leverage to disconnect the latch. Sigh. It was ... fine? ... while it lasted. (About the same price as a tank of gas for my old Jeep, so I can’t complain too loudly.) This time around I decided to go as inexpensive as possible while doing things “more right.” I also figured I’d future-proof a bit in the process. Folks recommended the Grizzl-E stuff (and the Mini looked like it could have worked, for $479), but I don’t see that it works with the L6-30 plug I have access to at the office. Primecom ships an L6-30 24A unit , but it too is $449. Instead, I went with a used Tesla Gen 2 Mobile Connector I found on Facebook Marketplace, fr...

AI wrote a Firefox extension for me

Image
Well, wrote it and then helped me tweak it. The prompts were easy. The code pretty straightforward. The functionality is very basic. It just takes the current page title and URL and, using the things:/// URL scheme , adds an item to the inbox. (Yeah, in Safari, the “Share ... Add to Things” option does the same thing in Safari. But I’m not using Safari.) This cleans up after itself, closing the tab that was opened to call the Things URL integration a second after it’s finished loading. I’m generally happy with it, with a couple of “punch list” items. https://pastebin.com/ckfftFfc ChatGPT: Original extension creation Modifying it to auto-close the newly opened tab  To do: Need to figure out why the keyboard shortcut isn’t working (“ keyboard shortcuts do work , but   only if the extension is installed as a permanent add-on , not as a temporary add-on via   about:debugging .”) Need to modify it to use the contents of the clipboard rather than the URL, if on certain cites (l...

New Guitar Day (H-1001). Guitar straps.

Image
Yesterday I stumbled across a great deal on an ESP LTD Deluxe H-1001 in “Violet Andromeda Satin finish.” ESP LTD H-1001 in Violet Andromeda Satin finish This thing is  sweet :  The first thing you’ll notice about the new LTD Deluxe H-1001 is its Violet Andromeda Satin finish. The Andromeda finish makes the guitar appear various shades of blue, violet, and even green as light is reflected from various angles. The H-1001 is the first LTD version of this outstanding design in a satin finish. It also features a set of direct-mount Seymour Duncan Sentient (neck) and Pegasus (bridge) pickups with push-pull coil splitting, a Hipshot bridge with string-thru-body, and stainless steel frets.   Maybe someday, this will be me?  Anyway. It checked  almost  all of my boxes:  ☐ Made in Japan ☑ Made in Korea ☑ Passive pickups ☑ Non-Floyd Rose (i.e., hard tail, Tune-o-Matic, EverTune [1]) ☑ Set-thru neck ☑ Locking tuners My (at this stage in life) dream g...
