Interestingly, AMD's previous gen processors, the K6/K6-2/K6-III, were all lidded flip chips. A delidded K6-era CPU looks remarkably similar to the early Athlons which did away with the lid.

I don't think it's possible to partially decode/render a PNG in a way similar to JPEG. The only exception I can think of is adam7 interlacing, which _does_ store the initial pass as 8x8 blocks, but I'm pretty sure PNGs w

In 2014 I went to the open house event that NASA Ames had in honor of their 75th anniversary. They had the giant 80 by 120 foot wind tunnel open for viewing from the outside and I had a very hard time comprehending the visual size of it bec

Interesting that Gemini said it was infeasible. It should be aware that using a Pico W as a transparent ethernet bridge has been done several times over in open source projects, for example on BlueSCSI (emulating a Daynaport SCSI-Ethernet a

I use acme.sh for certs on my personal server and was a little surprised when it started using ZeroSSL by default. Despite being more "corporate" I decided to roll with it and it's worked just fine.

They've already released the ESP32-S31-WROOM-3 and two development boards based on it: the ESP32-S31-Function-CoreBoard-1 and ESP32-S31-Korvo-1. All are available on Espressif's official Aliexpress store.

I had a Cyrix 6x86 when Quake first came out. My disappointment at how poorly Quake ran on it was significant, especially because pretty much every other game at the time ran well on the Cyrix. The FPU performance in Quake was doubly handic

Thank you - you're the first one who suggested that implementing GUS on a Pico w/ PSRAM was a possibility. :)

The VST itself is $20 (to the end user). The Enigma Protector is the software that costs $200 (to the developer).

BTW I'm pretty well versed in getting laser cut and bent sheet metal made, both in China and via US-based providers like SendCutSend - my PicoIDE project uses a metal bracket. In fact when so many other projects were using 3D printed b

Thanks. Fixed!

The repo will be made public when the hardware is launched. Should be a few weeks.

A stamped steel plate is not possible at my planned price point. But one thing I will note is that this 3D printed front panel is only a prototype.

by polpo 10mo ago
The price will definitely be lower, and another difference is that PicoIDE will be entirely open firmware and hardware, while ZuluIDE is not.

Currently, it implements the ATAPI READ SUB-CHANNEL command and fully supports the current position data format code. Other format codes like ISRC and UPC currently return dummy data, but wiring that up would be pretty straightforward. Supp

Fun seeing this posted - I'm the creator of the project. While it's meant to be a generic IDE/ATAPI emulator the two main use cases I envisioned for the project are in the area of retro computing: CD-ROM under MS-DOS and Wind

Outside of the US, they have symbols: ⇥ intead of "tab", ⇪ instead of "caps lock", ⏎ instead of "return", etc.

Did you actually read the article? Doesn't seem like it, the author says he literally talked to Peri in it.

That's a very uncharitable way to put things. Since my original posts it looks like things have cooled and the worst of the tariffs have been walked back, but at the sky-high tariff rates from before today, my options would have been:

I switched to Aisler who are in Germany. They're certainly more expensive than China but still way less than quick turn options in the US. There will still be tariffs but they won't be nearly as high. There are also smaller PCB ve

As a maker of open source hardware, I and others in the US selling my projects stocked up before the de minimis threshold was eliminated on May 2. We're not increasing our prices until those stocks run out and we have to reorder - we d

I use this to remember what it does and also like thinking of XOR as an operation you can apply with a mask to flip bits (the linked article mentions this).

I don't mind calling the connector an RJ45, but calling this thing an "RJ45 dongle" makes my eye twitch. It's an Ethernet dongle - RJ45 can be used for a lot of other things. For example I've seen "RJ45 dongles

I’ve replaced battery backed SRAM in several game consoles and other devices with FRAM (Neo Geo CD, Sega Saturn, an HP oscilloscope) and for some it’s drop-in, and in a few you have to bodge some lines.
