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.

Ok wait, so when it says 2.1" that doesn't include the bezel? So the problem all along has been me reading it wrong? Thank you!

Bear in mind I’m just reading the product page specs here but if you want me to measure mine I can dig it up!

Ugh, u may not like the following but the devices you are using to get on the internet, are used to collect a treasure trove of information, to conduct information warfare. And regardless of whatever your bullshit political specrum is.... this is a platform for stalking, propaganda, tracking and killing Human Beings.

Period.

Street Cred: I have common sense.

There is only one outcome: Defense spending, Military Death.

You flash the OS (okay, admittedly, debian which is nice) onto it from windows with some lugubrious .exe https://www.unihiker.com/wiki/burner No linux/macos tool available. No thanks.

Hah. Way too misread the room, are they serious?

Who even develops Windows-exclusive apps these days, anyway? Even the average user these days seems to find it simply abhorrent.

It's so simple to create cross-platform applications these days, there's literally no excuse.

I can't imagine the thought process that went behind this beyond greed and profit, a little mind-numbing.

Excuse my ignorance, but what sort of applications benefit from hardware acceleration on limited SoC resources?

Inferencing neural networks is a big one. It's hard to get near real-time performance without it. Depending on the use case of course.

Why on earth would you run ML on a potato?

> The UNIHIKER's pins are compatible with micro:bit They really bury the lede here, awesome that there is already an ecosystem that exists for the edge connector.

It's the same connector as on the BBC Micro:bit, right?

I was thinking the same, and it is!

Edge Connectors Pin numbers are compatible with micro:bit, 19 independent I/O (Support 1 ×I2C, 1×UART, 2×SPI, 6×12-bit ADC, 5×10-bit PWM)

Note: The edge connector on the back has no electrical connection.

This device is similar to many hacker festival badges from the recent years. Just a bit more expensive. For example: - the Camp 2023 flow3r badge https://events.ccc.de/2023/06/05/camp23-the-flow3r-badge/ - the MCH2022 badge https://wiki.mch2022.org/Badge - the SHA2017 badge with E-Ink https://wiki.sha2017.org/w/Projects:Badge - the Camp 2011 badge R0ket https://events.ccc.de/camp/2011/wiki/R0ket The first three have…

"If your badge has been hit by ransomware, see how to enter Safe mode." What a world we live in...

It was a joke and part of the actual hacker festival.

I purchased a few ARM boards in the past and won't do it again. All became e-waste. Rockchip notably, great hardware on paper. Try developing something that needs hardware acceleration and it's a paper weight. It's a common cycle of broken promises to provide drivers by manufactures, rinse and repeat. The exception being raspberry pi or expressif. Depending on the application.

I've had the same experience with non Raspberry Pi boards. They've become useless thanks to endlessly broken software and zero support. My rpi's have been useful for years and are still getting regular updates. I think I too was drawn in by the performance claims made by those other manufacturers. I realized though that raspberry pi are very powerful computers. We just take the scale of modern computing for granted a…

> ...just take the scale of modern computing for granted and our software is the real problem.

I was thinking how I constantly find myself using GPT and Bard to prettify source code. Surely, not the most efficient use of compute.

Like some crude Parkinson's Law joke on more proficient algorithms.

I wish the RAM could be a bit more, at least 1G or 2G, so I can have a database on there without having to ship my data to the cloud. Then the system can really run isolated as much as possible, for security and privacy.

It has 16GB of flash. Can't you put your database there?

This. Back in the day when we lacked RAM, especially on *nix based systems, it's absolutely normal to use the disk/flash as pseudo-RAM. This was just...a normal part of computing at the time, heh.

Of course, applications would respond shit slow this way, but in the case of a DB it'd be more than fine, no?

I’ve become very cynical of these types of tiny computer products. These computers are like puppies that tech nerds will gush over and buy impulsively, do a couple small things with, then never use again.

It seems like the smaller it is, the crazier people get.
