Latest in the dspod series of digital audio experiments - the dspod UP5k based on an iCE40 UP5K FPGA. It's also got flash, PSRAM, ADC, codec, digital I/O, USB fullspeed and a programmable clock generator. These FPGAs are neither fast nor particularly "roomy", but I'm curious to see how much I can cram into one in this context.
I'm particularly pleased with how the assembly went on this - reflowed all the SMT parts rather than doing some by hand and I think it turned out very nicely. Now to test.

I've been doing more work on my 40x8 LED clock. I'm using a Pico W with firmware written in Rust on embassy-rs. Got NTP syncing working, web control with a single page app and it has a useful API. Happy!

The enshittification escalates...

I walked away from tech almost four years ago with a case of burnout you could see from space.

The intervening three years have only made me more grateful that I left when I did.

(I wish all my friends and colleagues still chained to the oars had my opportunity.)

AWS Fired the One Employee Who Gave a Damn

Remember Tarus Balog, the AWS employee who rescued my deleted account when nobody else would? AWS just fired him. His proudest accomplishment in four years was saving my data. Leadership didn't care. The finale of a trilogy nobody asked for.

Remember 100 years ago when radiation was new and exciting and poorly understood, and companies were putting radiation into everything?

Thankfully we learned our lesson and will never make that mistake again.

My pico-clock that uses WiFi and NTP to give you accurate time. It also has a captive portal to allow you to set it up, and a cap-sensitive button along the top to show its current IP so you can connect to its web portal to adjust the timezone, disable the animations and adjust the brightness. I want to add an LDR so the display dims at night etc. Pretty happy with it.

And it’s not a bad thing.

EDIT: mad props to @tg for writing one of the best things I’ve read in ages. We remember the old ways!

The Boring Internet

The internet you grew up on isn't dying. A commercial veneer glued on top of it is. A visual essay about what actually persists.

@alangarf I've done a similar project, but worked within the confines of the 32x8 array by slightly squishing the seconds digits a bit, which I didn't hate in the end. Implemented using ESP8266s, and they contact NTP servers and automatically shift for daylight savings time. First one uses a WS2812 array, the second simple led arrays.

OMG…most of us would struggle to get such a great picture from a pitch back night on terra firma
