Just found this Chinese Open Source HardWare site and wanted to share this cute project with you.

That is an incredible price.

Add transport, tariffs and vat, and you could as well buy a cheap Android tablet from Walmart.

The comment section say they were using second hand component. Basically salvage yard parts.

also, they were taking advantage of free sampling of JLCPCB in China. The main pcb is basically free

The right device at the right time can spur all kinds of revolutions. Sous vide water bath cooking was based on a laboratory immersion heaters, the WRT54g router spawned OpenWRT et al., commodity arc welders became a key part of carbon 60 research, XBox Kinect sensors got repurposed for all sorts of proximity hacks. The recent fad for particular brands of child oriented power banks in the through hiking community is the most recent one I can think of.

So therefore it’s a long shot, but this device or a device like it could be the mutation that causes a Cambrian explosion in mobile hardware, albeit one where you ahen apparently need to glue the screen on yourself, post delivery. (See the below-fold video.)

I cross every one of my fingers!

Now it needs a 4G / 5G modem, and a camera, and it could be a compact phone,

This sounds interesting. Can you elaborate?

It doesn't fit into the list as a revolution (or even 'evolution') as it's just a high-density, compact and cheap battery [1] that turns out to be quite unsafe [2].

It's probably a reference to the Haribo power bank thing (which appears to be poorly made and dangerous).

gorgoiler2• 8 months ago

Through a chance piece of design, the leading power pack in terms of energy density is made by / branded on behalf of Haribo, a confectionary company:

What’s interesting is, like the other products, it was designed and marketed for one purpose but has become very popular for another. (Although in this case it could well just be a fashion, especially given how uniquely identifiable the product is.)

for me it's 11" tablet, I'm saving for this. prey for me y'all.

russdill• 8 months ago

Seems like there's still a bit of work to go:

1. The device restarts after running for a while after Wi-Fi is enabled. The problem may be due to insufficient power supply. 2. Overheating: The chip may overheat and restart.

But can they run Half-Life 2?

What about it? The site's in Chinese.

This looks like the perfect thing to replace my POS Jenn-Air oven's defective touchscreen control panel...

wronglebowski• 8 months ago

The RK3568 is an interesting choice, why no the H700 or something with a good amount of mainline kernel support already?

le-mark• 8 months ago

I don’t know about the h700, but some of those allwinner chips used to be super cheap around Covid. I checked and didn’t find prices? Does anyone know where the price is now?

NewJazz2• 8 months ago

Rk3568 doesn't have good mainline support??

plipt• 8 months ago

Site says it runs Linux

Does anyone have insights on how compatible that hardware might be? Or how it might compare to something like a Pinetab?

For some years I have been looking for a low cost tablet with good Linux support for use in home automation or information displays. Surprised there is still nothing like this in the Raspberry Pi ecosystem.

NewJazz2• 8 months ago

Pinetab 2 is the very similar rk3566 chip, so support would be somewhat similar (probably a lityle worse, since the device trees haven't had as much attention).

How does one get a board like this one made?

tuetuopay2• 8 months ago

Send it to JLCPCB + JLCSMT. The board was made with EasyEDAY (JLC's web PCB tool) which has a one-click "manufacture" button.

tuetuopay2• 8 months ago

What I find most impressive is the design was made using EasyEDA, JLC's web PCB design tool, and only on a four layer board. That BGA with DDR4 on 4 layers is something!

ACCount372• 8 months ago

Why people actually use those clunky web-based tools is beyond me. It's like using a normal design tool but worse in every conceivable way.

Renaud• 8 months ago

Is it though? EasyEDA is more than sufficient for most uses that don’t require large amounts of layers or components. It’s easy to pickup by a novice, has basic ERC, well integrated into LCSC ecosystem.

It doesn’t have the versatility of KiCAD but is lighter and easier for light use or occasional design of moderate complexity.

dsvf• 8 months ago

I keep wanting to get into Kicad, and the learning curve did become easier in the last years. But what I _want_ is to get a usable board into my hands, not just create a beautiful layout file. Historically, my pain points were were footprints, parts sourcing and SMT soldering. From a hobbyist-with-limited-time perspective, EasyEDA and the integrated JLCPCB assembly flow solved all these problems good enough that the hurdle to figure out how to do it with KiCAD was always higher. The minute I find a similar level of convenience in KiCAD + plugins, I'll gladly ditch being tied to online.

IgorPartola2• 8 months ago

I tried to start with KiCAD so many times and never could fully figure out how to do the basics of what I wanted to do. Mind you I was designing absolutely basic boards using capacitors, MOSFETs, resistors, some basic SMD sensors and ESP8266 modules. EasyEDA has a downloadable version that is significantly less clunky and the UI makes a lot of sense to an amateur. Plus of all the things I had tried it had me spend the least time finding footprints for components that were actually available and affordable. Nothing quite like picking out a capacitor just to find out that it costs $0.84/each while an equivalent but slightly different one would be $0.0037/each.

fainpul• 8 months ago

What worries me is that a lot of resistors / capacitors are placed at seemingly arbitrary angles. It looks messy and unprofessional. I wouldn't be surprised if this has many electrical problems due to amateurish PCB design.
