I’m still trying to get a Rock 5B to boot from NVMe. By all appearances they included a USB Type-C port that doesn’t work, so the system never pulls sufficient power not to boot loop. Apparently even after a firmware update. To be totally f

Our (Pi compatible) HyperPixel Round is just shy of 3” if you count the thick, black border around the edges. Actual screen is 2.1” but diameter is 71.8mm.

It’s been possible to use Bluetooth for a while, but a bug prevented Bluetooth and Wifi from running stably at the same time. I threw together a Bluetooth speaker firmware - for some of our (Pimoroni) boards - with FFT visualisation quite s

Airmash still lives at https://airmash.online/ and there’s also a space mod - Starmash - at https://airmash.cc/ I apologise in advance for the hours you’ll lose to these (again?)

Secret Lab Chairs still get away with listing totally imaginary “Non-Direct Pricing” despite the ASA saying- and I quote- “we think it likely to have breached the Advertising Codes (“the Codes”) that we administer.” And their 5-year warrant

Oh wait, did I forget about the Pi, Pi[co], Pi[nout] logo?- I was thinking of the earlier pixel-Raspberry logo.

Thanks! Aha, that was made in a bit of a hurry for pinout.xyz back in July 2013 when uhh I fell afoul of Raspberry Pi trademark terms! Necessity is the mother of invention.

That’s a good question- it could probably adopt some of the things I’ve learned from the Pico layout (light/dark modes for starters) but it’s left-aligned in order to fit text and details about individual add-on boards. It also once ha

How do I summon Jeff Geerling - he just interviewed Eben on this very topic. I can say that we - by which I mean my employer Pimoroni - will now sell you a whopping TEN Pi Zero W boards in one order.

It takes some time to decode, but I can grab- for example- this 259k JPEG: http://placekitten.com/3840/2160 And display it from the microSD card with this code: https://gist.github.com/Gadgetoid/0b

Yeah, they are very definitely not production grade! But we had laser cutters, mylar sheets, pots of solder paste, questionable quality spatulas and way too many different prototype PCBs. A means to an end.

It didn’t really stay personal, but I built a very basic Raspberry Pi Pinout website hosted on a Raspberry Pi [1] back in 2013. The intent was to collect the pinouts for some boards I was tinkering with at the time. It got wildly out of han

Laser cut Mylar stencils are an acceptable method of applying solder to pads if you have the means. And solder paste syringes are pricy but very, very handy if you need a little extra paste somewhere specific. Great little project! It’s bee

The frustrating twist is that - under the hood - this screen is CMYK. There’s a magenta “ink”, which would fill out a huge gap in the colour gamut, that we can’t even use. The same applies to cyan. Both colours are fundamental to the disp

I don't know. If I claimed to uphold the sacred tenets of free speech and expression I probably wouldn't want to be associated with a website that has a profound chilling effect on free speech and expression. Is hate and ridicule

I fear the definition of legal speech on our respective countries differs too vastly for me to venture any reasonable answer to this. I suspect our personal interpretations for what constitutes censorship might also. To lay out my position-

There’s no support for mapping external memory but you can apparently get creative: https://github.com/yocto-8/yocto-8/blob/main/doc/extmem.md

I haven’t come across an RP2040 I couldn’t overclock to 250+ MHz. Couple that with DMA into the PIO state machines and it smashes through stuff like the weird WS281X timings, HUB75 matrix scanning and even DVI and usually has a whole spare

Not quite the same ballpark yet, but I sincerely hope they get there. System76 are rolling their own distro - Pop!_OS - and their own tiling window management add-on - Pop! Shell - both of which I've switched to using even on a non S

I worked for ~3 months exclusively on the N5000 version, writing C++ drivers for the RP2040 (in VSCode) and binding them to MicroPython, plus tending our 32blit (STM32-based) project. Sure I would have used something a lot beefier if I had

I managed to hit power and enter in quick succession on the Mk III accidentally just a day or two ago so... yeah... I'd be in strong support of putting it somewhere less under my fingertips. Confused the heck out of me, I thought the b
