Why is there no OpenBanking API for personal use?
The recent news that MoneyDashboard is suddenly shutting down has exposed a gap in the way OpenBanking works. It is simply impossible for a user to get read-only access to their own data without using an aggregator. And there are very few aggregators around.
Why is it impossible for me to get programmatic access to my own data?
There are two interlinked reasons which I'd like to discuss.

Wired For Success
Our Qwiic connect system has not only taken our products by storm after being introduced by SparkX in 2017, but it's also being used across the industry as to simplify I2C for all types of applications!

PCIe / PCI Express: extenders and expanders
Continuing the series of blog posts on PCIe / PCI Express, this post looks at extenders and expanders. Note: Adafruit does not endorse any of the products in this post, links are for documenting sources.

Bleep Remover Censors Those **** Bleeps
One of the more interesting cultural phenomena is the ‘bleep’ that replaces certain words in broadcasts, something primarily observed in the US. Although ostensibly applied to prevent susceptible minds from being exposed to the unspeakable horrors of naughty words, the applied 1 kHz censoring tone is decidedly loud and obnoxious enough that its entertainment level falls somewhere between ‘truck backing up’ and ‘loud claxon in busy traffic’. There is thus a definite argument to be made to censor the censoring beep to preserve one’s sanity, which is the goal of [Oona Räisänen]’s Bleep-be-gone project on GitHub.

Using 5V Programmable Logic Here In The 2020s
Do you speak GAL? [Peterzieba] does, and has pulled together a collection of documents and tools so that you can too. There’s a dividing line in electronic engineering education, between those who were taught about FPGAs, and those who weren’t. Blurring that line slightly is gate array logic (GAL). These devices were a preceursor to the FPGA, with a much simpler structure, and usually in those days UV-erasable in the same manner as an EPROM. And oddly enough, they, or at least their successor compatible parts, are still available, and as handy DIP devices that talk to 5 volt logic.

LittleFS: The Emphasis Is On Little
It used to be that developing for microcontrollers was relatively relaxing. These days, even a cheap micro like the Raspberry Pi Pico has multiple cores, networking (for the W, at least), and file systems. Just like desktop computers. Sort of. I found out about the “sort of” part a few weeks ago when I decided to embark on a little historical project. I wanted a file system with a large file that emulates a disk drive. The Pico supports LittleFS, and I figured that would be the easy thing to do. Turns out the Little in LittleFS might be more literal than you think. On the plus side, I did manage to get things working, but it took a… well — dare I say hack? — to make it all work.

Autonomous Wheelchair Lets Jetson Do The Driving
Compared to their manual counterparts, electric wheelchairs are far less demanding to operate, as the user doesn’t need to have upper body strength normally required to turn the wheels. But even a motorized wheelchair needs some kind of input from the user to control it, which still may pose a considerable challenge depending on the individual’s specific abilities.
