Very impressive stuff! There are so many stupid comments here.

After reading the post, i was under the impression that the author really did some shopping for major components and assembled everything into a fun shape. Obviously i know nothing about electronic board design, so could you explain which extraordinary skill this required ? EDIT : ok, i missed the part where he actually designed the whole board, obviously..
Embedded systems engineers are (usually) paid a lot less than full stack engineers. Edit: I seem to be getting (a lot!) of downvotes on this. I thought it was quite well known, but apparently not. Full Stack Engineer salary: $93,598 [1] Embedded Software Engineer salary: $74,758[2] [1] https://www.payscale.com/research/US/Job=Full_Stack_Engineer...

Don't know why the downvotes either. Its not intuitive, but a sad fact of life and just the way supply and demand works.

Yeah, maybe it's a "I don't like this" vote. I tend to agree - I find embedded software engineering skills quite intimidating. Nevertheless, the market demand just isn't as high.

ethernet on a business card is just not as viable.

I think it's very considerate to not add lead to a business card people may put in their pockets.
Lead is restricted because of what happens to it when PCBs are landfilled, not because it is harmful to touch.
Washing your hands after handling solder seems to be a fairly universal recommendation. It's not a concern for normal products because the users do not touch the bare PCB.

#47Waw, I wasn't expecting the components to be that cheap. That said I haven't bought such components in a very long while.
It’s QFN though so you need a reflow oven to make the boards at home.
I’ve had bad experiences with the allwinner chips (the boards I had years ago were very unstable) but the mainline kernel support is very exciting. That you can order a few phones built around them now too is just awesome.

#48My eyebrows went up when I saw the processor was so cheap, but then I went and found a datasheet for it and...
$1.42 buys
- ARM926EJS core at 900MHz consuming 54mA when on and idle
- 32MB DDR RAM
- 720p H264 @ 30fps hardware decode
- Audio DAC capable of 192kHz over I2S
- USB OTG (not full host)
- LCD RGB (FPC) interface at either 1024x600 or 1280x720 @ 60fps
- Touchpanel I/O

My version of this would have a tiny LCD, buttons, and a Wi-Fi interface. I know all of those exist in incredibly inexpensive formats. Adds to todo list

That’s if you even have a USB A socket anymore!
I don't see why you were downvoted. I fully get why the blog writer didn't include USB-C with this awesome project. But there's now a growing group of people who simply can't use USB-A anymore with their laptops. Most will have an adapter, but not all.

Electronic waste, which is even worse than thoughtless waste. All this just so that he/she could “impress” potential employers.
Major Buzzkill is bucking for a promotion!
Truth being flagged just because it doesn’t look “cool”. This profession desperately needs a re-do. Otherwise I’m pretty sure that the person that flagged my statement really cares about the environment and recycles religiously.
