Flash cart(ridge)

“Windows cannot open this file.”
That is one, but I can unpack it on my Smart PC 200D.

“This program in unavailable on this version of Windows.”
That is the other one.

It is the same reason you cannot run Turbo Pascal without a emulator.

I finally changed the expansion connector on my Arduboy to male so the flashcart can slot in :slight_smile:


even without a case I think it looks cool. Maybe it’s just because Blinky sitting there on top :smile:

Hope I get those buttons soon so I can send some to @n602 for a slick case design :wink:

Oh, it came out at last!:heart_eyes:
I am preparing for the time to come.


It seems that flash-cart does not generate so much heat, but whether to open some ventilation holes …:roll_eyes:

I see you’ve made another design with holes. Seeing the orange yellow render I can’t help myself thinking about swiss cheese :smile:

The flashcart consumes very little power and produces no heat. So ventilation holes are not really needed. It’s an interesting design though and may be good for moist or airpressure sensor or insert LEDs into them and make a really bright flash light accessory. the holes at rear side give me the idea of making a Knight Rider scanner :smiley:

Or a headphone jack output
Think we can stuff some fpga stuff into that port?

After a long holiday break there’s some more developments.

Just before I went on holiday those buttons did arrive and was able to send some flash carts to @n602 so he could perfect his case design.

Last week I received @n602 perfected case design and they really are perfect :smiley: This weekend I soldered up the remaining parts I had left to make some more flashcarts so I could put them all in the colored cases :heart_eyes:

I’ll make some kits including backplate soon. So if anyone is interested in pimping your Arduboy with a bigger battery and/or flash cart, send me a PM.

They look amazing.

I’m still actually waiting on some level shifters to arrive after being messed around by some sellers over the past couple of months.

Oh, a lot of Flash-Carts are finished !!

The Flash-Cart and backplate data for 3D printers has been uploaded to Thingiverse.
thing:2853120 , " Arduboy replacement face/back plate"

9/06/2018 : Update
-addition of casing parts for Mr. Blinky’s Flash Cart system.
_

_

-For detailed information
To summarize the requirements and how to make it will be a long document, it was made into PDF.
Please find a readme pdf file,
readme-CasingPartsForFLASHCART_20180909.pdfthing:2853120

And you can download CAD data in .stp (STEP) format.
If you are interested in it, please get it and edit and improve it.

Thanks,

-Additional notes:
I noted that the PDF requires a LiPo battery for replacement.
However, if you process parts as follows, you can use the original battery as it is.
I noticed this by pointing out from @Mr.Blinky , Thank you.


Please be careful about battery handling, contact with signal wires etc, short circuit of power supply line.

Just a small update.

I had made some minor revision to the board and ordered some more in red last month. They arrived yesterday and turned out good. I’ve updated the board design on my Github.

Carts carts and carts :stuck_out_tongue_closed_eyes:

more storage? or a smaller cartridge?

just cosmetic changes :slight_smile:

Is the ghost blushing with vias or is there an intentional reason you didn’t cap the vias with soldermask?

I intentionally placed the blinky ghost and vias there for the blushing effect.

Did I miss where you said how much additioanl space this takes up in every sketch?

0 bytes as the loader is built inside the Cathy3K bootloader. Oh wait I should say -1K :smile: as Cathy3K frees up 1K more space for sketches (standard caterina bootloader takes 4K)

Ah, right. Awesome work here - but if we had to switch to reading an SD card and dealing with FAT, etc. I doubt it would still all fit in 3kb. :slight_smile:

…and I doubt it would work as solidly and consistently as this does! @Mr.Blinky has engineered a great solution here - why would you want to switch to SD cards?

I have seen so many issues, even with massive commercial products, where a particular brand or size or even specific batch of SD cards just don’t work - and it becomes a guessing game / experiment for users to hope that theirs will… not to mention all the hidden / system files that infiltrate an SD card every time a user plugs it in to a different machine!

I think @Mr.Blinky made the absolute correct decision moving away from SD cards and towards this design. I remember reading some comments on reddit from BennVenn (who has ‘been there’, and done the work of implementing low-level FAT / SD libraries) that really cemented it for me:

Anyway, if this leads to further discussion then let’s agree now to start a new thread about it rather than fill this one up with tangential debate! :wink:

I’d definitely would need that spare 1K for that. But i’m not persuing the SD card idea. In a nutshell flash memory is more reliable, lightweight to interface with and convenient.

Yeah, it’s pretty awesome. I just can’t really see the Arduboy 2 going that way. It really doesnt fit in your pocket if it requires you to carry around 20 flash cartridges with it. Otherwise it’s awesome. So many amazing cartridge systems over the years.
