Build log for the space cadet
Design principles
- non-split keyboard with a centered “thumb cluster” and side
Fnkeys. - Modifiers serve double duty (à la
xcape, although I currently employ a combination ofxcapeand a patchedevdevdriver).
Sourcing the material
Switches
I ordered 100 tactile gray from [http://www.doyustudio.com] and 100 super-heavy (150g) SPRiTs springs from [http://www.switchtop.com] I will use regular tactile gray for rows R1-R4, while the modded switches will be used for R5
Stabilizers
It was tricky to find Plate mounted stabs for the spacebar; I ordered a 60% set from [http://www.switchtop.com] and some OEMs from Vincent on AliExpress; he had 3u plate-mounted stabs! Hopefully they fit and I won't need to do any fiddling
Case
The case is a regular cheap acrylic case from KBDfans; it is 5 deg and I plan to 3dprint some feet to make it level
Plate
The plate was ordered through [http://www.lasergist.com]; ordered on [2017-11-06 Mon], shipped on [2017-11-08 Wed] and received on [2017-11-29 Wed]. The plate was received in the mail a bit warped; a bit of manipulation to straighten it up made it usable.
Controller
Teensy 2.0 ordered from [http://www.pjrc.com] on [2017-11-21 Tue], shipped on [2017-11-21 Tue], arrived on [2017-12-04 Mon]
Cabling
Re-purposing an ethernet cable (I guess it came with the Rogers router)
Keycaps
Round 5/6 leftovers from 7bit
Last batch arrived on [2017-12-04 Mon]

Programming the controller
Tools for flashing
There is a CLI interface available at [https://github.com/PaulStoffregen/teensy_loader_cli] and a GUI at [https://www.pjrc.com/teensy/loader_linux.html]; unclear if the sources are available
Emerging the cross-compilation
Following the guide at [https://wiki.gentoo.org/wiki/Arduino#Install_the_toolchain_using_crossdev]
We need to set up a cross-compilation environment; this can be done by emerging the package
sys-devel/crossdev, which seems to be just a wrapper script to emerge the right things
Let us see if this actually works; after emerging one supposedly has to run
crossdev -s4 --stable --portage --verbose --target avrand everything should be emerged… It FAILS, claiming that the avr-gcc cannot create executables; the workaround described in [https://bugs.gentoo.org/147155#c14] works

Issues
It turns out that crossdev needs to have its own overlay; we follow the recipies at [https://wiki.gentoo.org/wiki/Custom_repository#Crossdev]
mkdir -p /usr/local/portage-crossdev/{profiles,metadata};
echo 'crossdev' > /usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' > /usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev
