The 3dm files can't be opened by any non-paid software and the laser cutting services I'm aware of don't take raster, only vector files so the PNG is not useful. SVG is kind of a lingua franca, everything can import it but DXF is also good.
There is a regulator in schematics(U2). What's that name? and you need a filter capacitor for Vın and Vout.

Don't know if it's my clone of board being milled a bit small but I'm about a tenth of a mm short which makes it a pain to solder one side (actually haven't managed it yet...).
Think it would be much easier if the landing pads were extended half a millimeter inwards giving a bit of tolerance.
Very happy with my Mitosis so far with one small exception: I left it on my shelf for ~2 months and the battery was dead. I thought it should get more like 6 in standby. The variant I got from Flashquark has a housing which needs to be removed to get at the battery; this is a tad inconvenient.
I'm looking at putting in a lipo so I can at least change it without taking the housing apart. Is 3.7V something the board can handle natively, or would I need to put in a 3 or 3.3v regulator as well? The nRF nRF51822 specifies Supply voltage range 1.8 V to 3.6 V
which feels like pushing my luck.
EDIT: I'm a goof, I forgot 3.7 was the uncharged voltage, and at full charge it's more like 4.2. Most likely that's too saucy for the nRF. Leaving issue just to point out the battery consumption and see if anyone else has encountered this.
I read somewhere that there were plans to move to kicad but since there is no issue here i am making one.
There is the altium2kicad and kissboard project which could be helpful.
Especially the as far as i understand still untested but really good looking kicad components of the mitosis based kissboard could be a big help.
I'm a bit of an electronics noob; but the BOM only lists "Arduino Pro Micro", with no link or anything …
Amazon lists a ton of clones for that search — is the implication that any one of them will work? (In particular, there's at least two for sale, directly from SparkFun, with substantially different specs: a 5V version @ 16MHz, and a 3v3 version @ 8MHz.
Plz help a noob! <3
The Caps and Layers led is on the receiver,what about the keyboard one(two...)?
Am I missing some lines of the code ?
I like how the pcb has break out parts for the top plate which made me think that it should be possible to have the receiver be a break out part as well.
Then you would only have to buy 10pcbs and have 2 keyboards as well as the receivers which would just be superb.
so we can make some beautiful Acrylic case.
It's Awesome.
What You thing about this layout?
Fully programmable (rotor for 3d manipulating objects, volume etc.)
It looks from the receiver schematic like Pro Micro pin 3 (PD0) is connected to P29 on the NRF51 module (labeled P-D3) but I don't see anywhere that that connection is being used. What is it for?
your keyboard is seems to fit alps skcm switch, and i want to change the plate a little bit, thank you!
