item	price
trinkey QT2040	$8 USD
0.96in OLED	$3 USD
4pin JST-SH StemmaQT wire	$3 USD
TOTAL: $14 USD

setup

1. solder the 4 pin JST-SH connector to the OLED screen - the pinout is here
2. connect the now modified OLED to your QT2040
3. flash a circuitpython .uf2 file from here
4. "flash" the repository by git cloneing the project to your circuitpython equipped trinkey
5. profit

usage

everything is controlled by one button (the BOOT button), as the reset button cant be used

tap once to go down one, hold for 1-2 seconds to run
hold 3-4 seconds to set a script to autorun on next boot
hold for 4+ seconds to clear the autorun

to clear the autorun script w/o running anything, go into programming mode (view section below) and it'll automatically clear entering it - just press the reset button and boom to not run anything on start, hold the boot button about half a second to 1 second after the orangeish light flashes

adding scripts/programming

to program your qtkunai after it's been "flashed", you have to hold the BOOT button after it's booted (contradictory)
an easy way to do this is to hold the boot button while the yellow light flashes
hold the button until the neopixel turns blue, then let go for it to turn purple, meaning its enabled it's usb storage

to add a duckyscript script, just put it in the /duckyscripts folder - it'll automatically restart the kunai and show up

duckyscript syntax

the syntax for this is similar to duckyscript 1.0, supporting REM, STRINGLN, and some other things
most payloads will be supported by the qt-kunai, and if not, require basic editing
numbers wrapped in parenthesis must be an integer, never a string
quick reminder to remove the parenthesis when using

script command	description	usage
REM	remarks/comments	REM i am a comment
STRINGDELAY	write a string, with a delay between each space set in miliseconds	STRINGDELAY (1000) hello world
DELAY	sleep for X miliseconds	DELAY (1000)
DEFAULTDELAY	delay inbetween each command, set as miliseconds	DEFAULTDELAY (1000)
STRING	write a string, not ending in a newline/enter	STRING hello world
STRINGLN	same as above, but ends in a newline/enter	STRINGLN hello world
REPEAT	repeats the previously executed line X amount of times	REPEAT (25)
COLOR	sets the color of the neopixel as RGB, no brightness	COLOR (255) (255) (255)
PRINT	prints to the display text at X and Y coordinates (no wordwrap)	PRINT (4) (8) hello world
SCNCLR	clears the OLED display	SCNCLR
LEFTCLICK	left click at current mouse position	LEFTCLICK
RIGHTCLICK	right click at current mouse position (how obvious)	RIGHTCLICK
WHEEL	scroll the mouse wheel - positive integer is up, negative is down	WHEEL (100)
MOUSEMOVE	move the mouse - view X,Y syntax here	MOUSEMOVE (100) (100)
GUI	press a key with the GUI key	GUI r
ALT	press a key with the ALT key	ALT F4
CTRL	i think you know what this one does	CTRL d
