Oh hey that’s my Floppy8! Never woken up to find my stuff on HN before! So cool!

I actually just released a video earlier this week about the progression of my SD card based cartridges[0] which started with the floppy cartridges for this. If you like the Floppy8 you’ll probably enjoy seeing the dozen iterations I went through after this blog post haha

I’m mostly a YouTuber not a blogger so I have a bunch of other projects on my channel[1] in a similar vein which you might enjoy as well.

Looks like Germany Navy[0] want to some how emulate floppy disks. Maybe the you can make a living out of that.

Heh, was just about to post that this design ended up having issues with chafing between the sdcard read and the sdcard and that the new design (for the reader part at least) addressed this. I love the new version and have been contemplating making one myself. Very nice videos and description, so thank you for sharing your projects

Haha yes, I'm still not used to people knowing so much about my projects, thank you for watching!

How did you find the servo to eject the cartridge? You mentioned occasional jams, is that because of the style of cog, or the lack of pressure from the servo? I wonder if there is some tensing or alignment issues from the plastic cog..

I wonder if metal would better.

It actually never jammed I was just afraid that it would! It's just a generic micro servo, I think from Adafruit probably.

Ohh I mis-read that then. Thanks for the reference. I'm just getting into electronics myself and that site looks great.

You are absolutely insane. Bravo!

Which temperature-sensitive filament did you use for the thermal test?

It was the AMOLEN Color Change PLA. Sadly I just took a quick look and don’t see it available anymore, but I might be missing it.

Thanks, I did a quick search and I only saw TPU options.
