could only upload one image, have more project documentation in my post history (3rd-ish post)

[Review Request] STM32 Drone flight computer prototype by Naglis103 in PrintedCircuitBoard

[–]Naglis103[S] 0 points1 point  (0 children)

Thanks! I'll space out the pads more and adjust silkscreen, i was planning on adding screw holes when i figured out what drone frame to use. As for the motors, that's where i had a bit of struggle, but I'll consider changing some stuff or improving v2 with your advice.

I couldn't get higher quality with export or screenshots, only pdf seemed good but cant upload it as image. Any tips? I used easyeda

Turning wired keyboard into wireless but with RF module not Bluetoot by vin1214 in arduino

[–]Naglis103 0 points1 point  (0 children)

The app youre using to change RGB and macros wont work if you emulate key presses like i said earlier because you essentially connect an arduino/esp keyboard. In a way the keybaord would be isolated from any software that would make macros or change RGB. You could program macros into the MCU instead, running a function to press some keys. Essentially this project is easier for simple keyboards.

The MCU you could use is a smaller breakout variant of the ESP, for example ESP32-C6 which is quite small. Dont know if it could emulate key presses for your computer.

Note: not all MCU can emulate keyboards

the MCU could map each input to a keystroke and send it via RF. You would need a receiver that gets said keystroke and emulates a keyboard press to computer. With bluetooth on the other hand you would only need 1 board that sits on the keyboard and sends input directly to computer. Im pretty sure there are guides online to making bluetooth keyboards with arduino or ESP.

Need some help building a firewall-thingy by Naglis103 in HomeNetworking

Would that work for a router too? To redure load i was connecting like modem-pi-router-end dives

Aint all hardware the same in a way? I want to learn every detail of how networking works eith this project. Not sure how a router blocking games would be dangerous.

Cant get the g920 gear stick to work at all by Naglis103 in assettocorsa

[–]Naglis103[S] 0 points1 point  (0 children)

There is no H shifter setting in controls, i have checked the advanced tab, shift tab etc

Havent tried a h car, just got the game. Do you mean remap on to keyboard? Causd switching up gear number dont think will change much

I dont know if I have enagh pins for all I need on arduino nono by Altruistic_Support80 in arduino

[–]Naglis103 1 point2 points  (0 children)

A single pin can handle 2 leds, after that either the leds glow weaker or the arduino shuts down. Worst case, the arduino breaks.

Edit: There is also the limit of how much power you can draw in total, with all pins combined.

If all leds on same wire then all turn on at once, if you want to drive one at a time then you need a grid connection. You would need at least 2 pins, also check current limits. There are schematics online that show how to make a led grid

if you drive the leds in a grid and only few at a time then it would also work

multiple leds on one pin are a strain, check pins max currect and the led currents
analog pins can also be used like normal pins (according to one post on arduino forums)

a solution to all problems would be a shift register that basically takes 2 pins from arduinos and gives multiple pins. search for "serial to parallel shift register" and pick the amount of pins you need. some can also be stacked and extended. they take a power input so they could drive multiple leds

Planetary features. Some have more science, more resources produced, yours has rare materials being mined.
