up to no good

i shouldn't be surprised that this works but i needed a win

i can now type a post with the nc100 keyboard

it's happening!!!

i need to make permanent fittings for everything and get much thinner and shorter cables to plug everything together without spaghetti spilling out of every orifice, and then figure out a power solution (i'd like something that the pi can battery monitor on, which seems like nobody has ever done, everybody just plugs a powerbank and prays) but the main concept is solid

and oh yeah the screen is capacitive touch so mouse input is sorted too

yes, it does

never assume that just because the connector is the same the polarity is.. i've now repinned the battery but not before probably killing this UPS HAT

which specifically has no diode protection

yep it's gotten here this morning and in less than a day i killed it

so these are the internals otherwise so far

• RPi 3B 1GB
• DietPi (might change my mind later)
• RPi Pico running a very quick slapdash circuitpython script to turn the unharmed NC100 keyboard into USB HID (charmed by how easy that was)
• a new dfrobot UPS HAT has been ordered, should give me I2C monitoring so i can get that into the OS
• 10000mAh battery (might been a mistake given clearances but i'm winging this
• screen is 1280x480, takes HDMI and USB for power and touch

currently everything is double-sided taped down, the internal USB stuff (keyboard, screen) has been soldered straight onto the removed headers to make clearances work, i have a flat cable breakout for hdmi to make that fit in

the ports at the back will be located with a 3D printed plate i need to design yet

i'm still not sure how the screen will attach because id like it to sit at an angle, need to think about a way to hold it in place

oh i also have a tiny mono audio amp coming and i plan to use the tiny little speaker that comes with the nc100

that's not bad for a dinky speaker that was rated only for bbc basic beeps
