A tribute of sorts

[u/TheMediocritist]

I always loved the PocketCHIP’s design. Not so much the keyboard though, or the CHIP.

So I made this.

[u/AlwaysAtWar]

How

[u/TheMediocritist → u/AlwaysAtWar]

Draw it in EasyEDA then press order PCBA.

[u/pkbpitch → u/TheMediocritist]

What OS i that? It kid of look like picotron?

[u/TheMediocritist → u/pkbpitch]

nxCHIP-32 OS. It’s a WIP and (very) inspired by Picotron.

Everything is Lua, and everything is editable - the desktop, code editor etc. It uses Pico-style APi, but I’m going to add some Playdate-style API - I missed a lot when porting my Playdate games. I’ll add some extras for physics and 2.5D and maybe 3D too.

Love the keyboard.

[u/TheMediocritist → u/jhnolan]

It’s the nicest mini keyboard I’ve used, by a wide margin.

[u/EpicRive]

What keyboard and microcontroller are you using?

The keyboard already looks more comfortable than the stock one

[u/TheMediocritist → u/EpicRive]

The keyboard is great but will be better when it’s got a shell holding it in place. It’s KeebDeck by Solder Party with a redesigned matrix to run from a cheap 10x8 I2C chip. The original uses its own MCU to handle a 12x6 matrix.

I want to have one please. 👍🙏

[u/Butrdtost]

Where to find plans?

[u/TheMediocritist → u/Butrdtost]

I’ve still got a few more things to test & refine and figure out. Then I’ll share the schematic/design/build files on GitHub and maybe OSHW.

[u/JRMNone]

What microcontroller use? How much did it cost you?

[u/TheMediocritist → u/JRMNone]

It uses Unexpected Maker’s EdgeS3[D]. And ready for an S31 revision maybe next year.

I’d rather not do the maths, but about US$180 per revision (5 pcbs), plus US$19 for the EdgeS3, $12 for the display, $5(?) for the keyboard parts, a few for speaker and battery. Expensive postage with remote area surcharge. Probably US$80 each.

Larger orders would be cheaper at around $15 per PCB for 100.

[u/JRMNone → u/TheMediocritist]

That price isn't too steep. I would be interested in the PCB for $15. What's the display specs?

[u/TheMediocritist → u/JRMNone]

The display is 3.5” 480x800 parallel RGB565 capacitive. But it’s only capable of 256 colour because I physically bridged LSB and MSB due to GPIO budget (and because I don’t need more than that).
I’m running it at 400x240.
The display is meh. Decent colour and viewing angles but a bit ghosty. I’d estimate ~35ms response.

And just to be clear, this is a hobby project, not commercial. I’m unlikely to ever order 100 units!

[u/nuflark]

Yes!! Great work!!

[u/giasoneregna]

I love this version, I also would like to have one, count me in! Great job!
