My bass setup

Image
Yamaha bass, Fender amp, my audience Grabbed a “starter” bass, the Yamaha BB234 , and paired it with a Fender Rumble 40 [1]. Added on the usual assortment of accessories, like a cable , strap , tuner , heavy picks (’cause the first song I’ve been learning is Opiate , and, well, Paul D’Amour plays with a pick ). For the Fender I also picked up the  099-4049-000 foot switch to toggle between its modes, and for convenience this  C14 to C13+NEMA 5-15R Y Splitter Power Plug Cord so I can plug in the NUX MG-300 Mk. II (which has some bass heads and IRs and pedals, to augment the basic massaging the Rumble 40 has built in), without running another cable back to the wall. I’ve also been using it with headphone amps: Boss Katana:GO (had picked up a discounted used one to use with guitar, but it’s got a good bass mode) with a pair of AKG K92 headphones (which I already had) (cable hell, but it can also be used as an audio interface)] Positive Grid Spark NEO  (better interface...

Cheaper stylus options for the Kobo eInk readers

Image
I have a Kobo Elipsa 2E  (came with a stylus) and I’m thinking about adding a Libra Colour , which also supports a stylus. (My Libra 2  does not ; the other models that do  are the discontinued Sage and the original Elipsa .) I want to be able to easily highlight text, and add notes. The official stylus is $70, but, it turns out it uses the Microsoft Pen Protocol (MPP) , so any stylus that works with a modern Microsoft Surface tablet should work with the Kobo. Like this $20 unit (or this $29 model ). (The former can be equipped with these replacement nibs ; not sure about the latter.) The $20 SKU, Amazon’s AI said it wouldn’t work, but multiple reviews said it works just fine (search for “Kobo” and use the “Show related customer reviews and Q&A” option); for the $29 product, Amazon’s AI offers: Yes, the ASUS Stylus Pen you're looking at works with Kobo devices! One customer specifically mentions it "works well with Kobo devices" in their review. Key features for Kob...

Integrated Circuits - A Brief History

Image
Very brief, and incomplete, but I’ll add to it as I go. In the beginning (the 1970s), CPUs shipped in Dual In-line Package (“DIP”) packaging: DIP These were ubiquitous in the late 70s and early 80s, but they became impractical above 40 pins, which led to some interesting design compromises, like the 24-bit address bus and 16-bit external data bus of the Motorola 68000: But these could be through-hole mounted, or socketed, and it was what it was. Following that, we start getting into interesting diversions, like 68-pin PLCC (Plastic Leaded Chip Carrier) and 68-pin Ceramic LCC (Lead Less Chip Carrier) packages, commonly seen on the 80286, starting in the early 1980s: PLCC CLCC Starting more-or-less around the era of the 80386 and the 68030, came Pin Grid Array, used for, e.g., socketed (and through-hole soldered) CPUs through the mid-2000s at least, when Intel switched to Land Grid Array (LGA) for the Pentium 4 (and a couple of years later, moved Xeon over) (AMD still uses PGA for ma...

Using Google Authenticator with a web browser

Image
I’ve been using Google Authenticator on my phone for sites that require MFA. But picking up my phone to obtain a code is fraught with potential distraction / derailment. (Kind of an event boundary / doorway effect kind of thing.) So I was stoked to figure out I can add an Authenticator extension to Chrome to retrieve tokens ( authenticator.cc ). To export my accounts from the phone app, I had to go through one by one to generate QR codes, AirDrop a screen shot of the code to my laptop, and then import in the extension. A bit clunky, but I really only have to do it once (well, once for every device you want to use the extension on, sigh...). Adding the extension In Chrome (or apparently, also, FireFox, though the instructions will differ somewhat), use the ⋮ menu, Extensions, Visit Chrome Web Store, and search for Google Authenticator. Add the authenticator.cc extension: Me, I like to have something I’m going to use that often, pinned to my toolbar: Exporting accounts from the iP...

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 . Edit: It’s not. The tip of the refill gets stuck going into the tip of the pen. Amazon’s AI suggests a Schmidt 888 , or the Graf Von Faber ...

Using an iPad as a second screen

Image
Not sure why it took me this long to learn how to do this (it took like 3 clicks). The Displays control panel in system settings Update: And then, inevitably, I started accessorizing. To put it at eye level when used with the arm-mounted monitor on my sit-stand workstation, or with a laptop elevated on a Moallia laptop stand / riser , I found this AiFeelife Height Adjustable Portable Monitor Stand to be the best compromise of quality, available height, reported durability, flexibility, and sturdiness ($38; make sure you get the one with the wingnut-looking “adjustment knobs,” the reviews of the ones that are Allen key adjusted are fairly negative). It should also fit my 16" portable 2K monitor, though I haven’t tried that yet. Dining Table Workspace: Portable monitor stand holding 10th gen iPad

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...
