I'm testing Adlink's Ampere Altra Developer Platform. This machine has a 96-core Arm CPU, but now they sell a 128-core version. Apple also recently released the M2 Ultra Mac Pro, so the model I'm testing isn't the "fastest in the world" like I could boast a couple months ago... but it's close, and I actually doubled my performance from last time—I'll show how later.
Last year, due to some extreme luck and help from a viewer, I picked up an AMD RX 6700 XT for MSRP (around $500).
My initial goal was to see if I could get the card working on a Raspberry Pi. Though my initial effort was fruitless, I've since hacked the driver to work through at least a few 'rings' of AMD's doorbell init process.
Update: I was able to get everything to work—but I couldn't get the RX 6700 XT's drivers installed in Ubuntu. There are probably a few reasons for that... but it definitely wasn't as straightforward as I had hoped. I'll post an update soon.
Last year, in my work towards bringing up a graphics card on the Raspberry Pi, I was fortunate enough to acquire an AMD Radeon RX 6700 XT at near-retail price (thanks to a viewer who assisted my luck!).
This year, as part of a slightly-zany video building a Raspberry Pi into a standard desktop PC, I was able to gather enough parts to make up a halfway-decent gaming/creative PC centered around the RX 6700 XT, and instead of putting it together myself, I thought I'd share in the potential disaster in a live stream—tune in at 10 a.m. US Central time on March 3 (or watch below):
I often like exploring what's possible on a Raspberry Pi (or other low-end hardware). One area I haven't explored much is GPU performance. I typically run my Pi's headless, and have only dabbled in embedded machine vision with Pi cameras, so most of my experience is on the programming / software side.
But seeing Apple's 120 Hz 'ProMotion', and ever-higher refresh rates in the enthusiast gaming realm (we may hit 480 Hz soon!), I wanted to see how a tiny Raspberry Pi could perform in this realm.
The Pi's VideoCore GPU can output 1080p at refresh rates up to 120 Hz—at least there's a setting for it. But I'd never tried it. The hardest I pushed a Pi was 4K at 60 Hz for my Pi 4 a Day challenge, and that didn't go as well as I'd hoped.
As a kid, I never had a Game Boy, Game Gear, or any other handheld console. Heck, as luck would have it I've never owned a Nintendo Switch, either.
I've played console and PC games, I've only used handhelds twice: once in middle school, when a friend let me borrow his Game Gear for a day, and last year year when my dad brought over his Nintendo Switch—which my kids quickly commandeered.
I guess out of a sense of jealousy, I decided the first thing I should do with Raspberry Pi's latest hardware, the Pi Zero 2 (see my review here), is build myself a handheld retro gaming console.
And what better way than with the Null 2 kit (pictured above, from it's Tindie page), a kit integrating off-the-shelf components on a custom PCB, wrapped up nicely in a custom acrylic case.
I've watched a few episodes of 'The Minecraft Project' on YouTube for inspiration, and I occasionally play Minecraft for an hour or two as a diversion (it's like LEGOs on a computer, but much more fun, because there are zombies!).
My humble little Minecraft farm.
One thing I've always liked is The Minecraft Project's look and feel, mostly due to syndicate's use of the DokuCraft Light texture pack. However, getting that texture pack to work along with other mods and patches (especially the automatic tool switcher mod) took some work on my Mac, and I thought I'd post my process for getting everything to work here, for the benefit of others having the same troubles (especially those getting the 'Use the patcher noob' messages where water, lava, etc. are supposed to appear):
About a month ago, when I was settling down with my wife to watch a quick episode of Cake Boss via Netflix, I turned on the Xbox 360, but all the sudden, I received (for the third time on this Xbox) a nice present from Microsoft: the dreaded red ring of death (RROD).
"Not to fear!" said I, "I'll get a free warranty repair, like I did the first two times this happened!"
Little did I know. Luckily, however, I found a guy via Craigslist who repairs Xboxes and lives in St. Peters, MO (not too far from here!).
